CROSS-REFERENCE TO RELATED APPLICATION

[0001] This application claims priority from and the benefit of U.S. Provisional Patent Application No. 63/525,084, entitled “HEAT PUMP AND HEAT STORAGE FOR HVAC&R SYSTEM,” filed July 5, 2023, which is hereby incorporated by reference in its entirety for all purposes.

BACKGROUND

[0002] This section is intended to introduce the reader to various aspects of art that may be related to various aspects of the present disclosure, which are described below. This discussion is believed to be helpful in providing the reader with background information to facilitate a better understanding of the various aspects of the present disclosure. Accordingly, it should be understood that these statements are to be read in this light, and not as admissions of prior art.

[0003] A heating, ventilation, air conditioning, and refrigeration (HVAC&R) system may utilize a working fluid (e.g., a refrigerant) that changes phases between vapor, liquid, and combinations thereof in response to exposure to different temperatures and pressures within components of the HVAC&R system (e g., vapor compression system). The HVAC&R system may place the working fluid in a heat exchange relationship with a conditioning fluid (e.g., water) to heat and/or cool the conditioning fluid and may then deliver the conditioning fluid to various destinations to be utilized. For example, the HVAC&R system may include a heat pump system (e.g., heat pump vapor compression system) that includes one or more heat exchangers, where each heat exchanger is configured to receive a respective flow of working fluid and a respective flow additional fluid and to place the working fluid in the heat exchange relationship with the additional fluid. [0004] In general, energy transferred by a first heat exchanger of the heat pump system (e g., heat transferred from the working fluid to a first additional fluid) may be approximately equal to a combination of energy transferred by a second heat exchanger of the heat pump system (e.g., heat transferred from a second additional fluid to the working fluid) and energy consumed by a compressor of the heat pump system. However, heat pump systems may be utilized in applications having variable cooling loads and/or heating loads. Thus, existing heat pump systems may operate inefficiently in various operating conditions. Accordingly, improved heat pump systems that more efficiently and/or effectively satisfy varying heating and/or cooling loads are desired.

DETAILED DESCRIPTION

[0018] One or more specific embodiments will be described below. In an effort to provide a concise description of these embodiments, not all features of an actual implementation are described in the specification. It should be appreciated that in the development of any such actual implementation, as in any engineering or design project, numerous implementation-specific decisions must be made to achieve the developers’ specific goals, such as compliance with system-related and business-related constraints, which may vary from one implementation to another. Moreover, it should be appreciated that such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking of design, fabrication, and manufacture for those of ordinary skill having the benefit of this disclosure.

[0019] When introducing elements of various embodiments of the present disclosure, the articles “a,” “an,” and “the” are intended to mean that there are one or more of the elements. The terms “comprising,” “including,” and “having” are intended to be inclusive and mean that there may be additional elements other than the listed elements. Additionally, it should be understood that references to “one embodiment” or “an embodiment” of the present disclosure are not intended to be interpreted as excluding the existence of additional embodiments that also incorporate the recited features.

[0020] Embodiments of the present disclosure relate to a heating, ventilation, air conditioning, and refrigeration (HVAC&R) system. The HVAC&R system may include a vapor compression system (e.g., a vapor compression circuit) configured to circulate a working fluid (e.g., a refrigerant, water) to cool and/or heat a conditioning fluid (e.g., water, water and alcohol mixture). In particular, the vapor compression system may be a heat pump system that includes one or more heat exchangers, where each heat exchanger is configured to receive a working fluid and a respective additional fluid and to place the working fluid in a heat exchange relationship with the additional fluid. The heat pump system may be a generally thermally balanced system. For example, energy transferred by a first heat exchanger of the heat pump system (e.g., heat transferred from the working fluid to a first additional fluid) may be approximately equal to a combination of energy transferred by a second heat exchanger of the heat pump system (e.g., heat transferred from a second additional fluid to the working fluid) and energy consumed by a compressor of the heat pump system. It is now recognized that heat pump systems may be more efficiently implemented with processes and/or applications having a heating load and a cooling load. For example, in accordance with present techniques, a heat pump system may be implemented with a distillation system to provide heating and/or cooling that enables distillation of a fluid (e.g., a liquid). In this way, distillation operations may be performed more efficiently, at reduced cost, and with reduced energy consumption.

[0021] As described herein, a heat pump system may be incorporated with various distillation systems to enable distillation operations (e g., distillation process, process for distilling and/or concentrating a mixture or liquid, evapo-concentration, desalination, water distillation). In such applications, the heat pump system may operate to supply heat and/or steam (e.g., vaporized water, vaporized water and alcohol mixture) to a distillation vessel (e g., distillation column) and to cool and/or condense a vaporized fluid (e g., alcohol vapor). Unfortunately, heating loads (e.g., target temperatures, desired heating loads and/or temperatures) for some stages (e.g., steps, operations, batch stages) of the distillation operations may vary. Thus, existing heat pump systems may cause inefficiencies in certain stages of the distillation operations. In particular, a heating load of the heat pump system may be higher or lower than a target heating load (e.g., target temperature, 70° Celsius (C), 70°-80° C, etc.) of one or more of the distillation stages of a distillation operation. For example, excess heat may be produced due to a heat load of the heat pump system being higher than a target heat load of the one or more of the distillation stages. Therefore, improved heat pump systems that more efficiently and/or effectively satisfy (e.g., match, correlate) the varying heating and/or cooling loads of distillation operations are desired.

[0022] Accordingly, embodiments of the present disclosure are directed to an HVAC&R system that may include a heat pump system and a heat storage system configured for operation with a distillation process. The heat storage system is configured to remove and store excess heat (e.g., rejected heat, as a heated fluid) from the heat pump system to enable the heat pump system to more efficiently and/or effectively satisfy (e.g., match) the varying target heating and/or cooling loads of the one or more stages of the distillation operations. Thus, the heat storage system increases the efficiency (e.g., energy efficiency) and cost effectiveness of the heat pump system with the distillation process. In addition, the heat storage system may be configured to enable use of the stored heat in various stages or operations associated with the distillation process, such as sanitizing (e.g., cleaning) components of the distillation operation (e.g., the distillation vessel) between batch processes and/or for pre-heating the components of the distillation operation (e.g., during initiation of a new batch process). In some embodiments, the heat storage system may be configured to enable use of the stored heat in other processes and/or operations of the HVAC&R system. In this way, the heat storage system with the heat pump system may further increase the efficiency (e g., energy efficiency) of the distillation operations by using the stored heat (e.g., excess heat) in various distillation stages, such as stages having a target heating demand higher than the heating output (e.g., current heating output) of the heat pump system.

[0023] For illustrative purposes, the following discussion is directed to a heat pump system and a heat storage system integrated with or configured to operate with a distillation system or process. However, it should be appreciated that the disclosed features and techniques may be used with other systems and processes. In particular, the heat pump system and the heat storage system may be implemented with other types of processes that include varying heating and/or cooling loads. In addition, the heat pump system and heat storage system may be integrated with or configured to operate with systems and/or processes in which heat is applied (e.g., by the heat pump system and/or heat storage system) to a mixture to enable separation of the mixture into its constituents and produce a more purified and/or more concentrated end product. For example, the heat pump system and heat storage system may be integrated with or configured to operate with an evaporation-concentration system or process, a desalination system or process, a water distillation system or process, a water purification system or process, a system or process for distilling and/or concentrating a mixture or liquid, and the like. As with the distillation system or process, the disclosed features and techniques may increase the efficiency and cost effectiveness of these processes by enabling the heat pump system and heat storage system to more efficiently and effectively satisfy (e.g., correlate, match) the varying heating and/or cooling loads of these processes. In addition, heat stored by the heat storage system may be used in various stages or operations associated with these processes, such as stages having a target heating demand higher than a heating output (e.g., current heating output) of the heat pump system (e.g., sanitization processes, between batches, initiating a new batch, and/or pre-heating components used in these processes.)

[0024] Turning now to the drawings, FIG. 1 is a perspective view of an embodiment of an environment for a heating, ventilation, air conditioning, and refrigeration (HVAC&R) system 10 in a building 12 for a typical commercial setting. The HVAC&R system 10 may include a vapor compression system 14 (e.g., a heat pump system) that supplies a chilled liquid, which may be used to cool the building 12. The HVAC&R system 10 may also include a boiler 16 to supply warm liquid to heat the building 12 (e.g., principal location) and an air distribution system which circulates air through the building 12. The air distribution system can also include an air return duct 18, an air supply duct 20, and/or an air handler 22. In some embodiments, the air handler 22 may include a heat exchanger (e.g., plate heat exchanger) that is connected to the boiler 16 and the vapor compression system 14 by conduits 24. The heat exchanger in the air handler 22 may receive either heated liquid from the boiler 16 and/or chilled liquid from the vapor compression system 14, depending on the mode of operation of the HVAC&R system 10. The HVAC&R system 10 is shown with a separate air handler on each floor of building 12, but in other embodiments, the HVAC&R system 10 may include air handlers 22 and/or other components that may be shared between or among floors.

[0025] FIGS. 2 and 3 are schematics of embodiments of the vapor compression system 14 that can be used in the HVAC&R system 10. The vapor compression system 14 may circulate a working fluid (e.g., refrigerant, water) through a circuit starting with a compressor 32. The circuit may also include a condenser 34, an expansion valve(s) or device(s) 36, and a liquid chiller or an evaporator 38. The vapor compression system 14 may further include a control panel 40 that has an analog to digital (A/D) converter 42, a microprocessor 44, a non-volatile memory 46, and/or an interface board 48.

[0026] Some examples of fluids that may be used as working fluids in the vapor compression system 14 are hydrofluorocarbon (HFC) based refrigerants, for example, R- 410A, R-407, R-134a, R-1234ze, R1233zd, hydrofluoro olefin (HFO), "natural" refrigerants like ammonia (NH3), R-717, carbon dioxide (CO2), R-744, or hydrocarbon based refrigerants, water (e.g., water vapor), a water mixture (e.g., water and alcohol mixture), or any other suitable working fluid. In some embodiments, the vapor compression system 14 may be configured to efficiently utilize working fluids having a normal boiling point of about 19 degrees Celsius (66 degrees Fahrenheit) at one atmosphere of pressure, also referred to as low pressure working fluids, versus a medium pressure working fluid, such as R-134a. As used herein, "normal boiling point" may refer to a boiling point temperature measured at one atmosphere of pressure.

[0027] In some embodiments, the vapor compression system 14 may use one or more of a variable speed drive (VSDs) 52, a motor 50, the compressor 32, the condenser 34, the expansion valve or device 36, and/or the evaporator 38. The motor 50 may drive the compressor 32 and may be powered by a variable speed drive (VSD) 52. The VSD 52 receives alternating current (AC) power having a particular fixed line voltage and fixed line frequency from an AC power source, and provides power having a variable voltage and frequency to the motor 50. In other embodiments, the motor 50 may be powered directly from an AC or direct current (DC) power source. The motor 50 may include any type of motor that can be powered by a VSD or directly from an AC or DC power source, such as a switched reluctance motor, an induction motor, an electronically commutated permanent magnet motor, or another suitable motor.

[0028] The compressor 32 compresses a working fluid vapor and delivers the vapor to the condenser 34 through a discharge passage. In some embodiments, the compressor 32 may be a centrifugal compressor. The working fluid vapor delivered by the compressor 32 to the condenser 34 may transfer heat to a cooling fluid (e.g., water or air) in the condenser 34. The working fluid vapor may condense to a working fluid liquid in the condenser 34 due to thermal heat transfer with the cooling fluid. The liquid working fluid from the condenser 34 may flow through the expansion device 36 to the evaporator 38. In the illustrated embodiment of FIG. 3, the condenser 34 is water cooled and includes a tube bundle 54 connected to a cooling tower 56, which supplies the cooling fluid to the condenser 34.

[0029] The liquid working fluid delivered to the evaporator 38 may absorb heat from another cooling fluid, which may or may not be the same cooling fluid used in the condenser 34. The liquid working fluid in the evaporator 38 may undergo a phase change from the liquid working fluid to a working fluid vapor. As shown in the illustrated embodiment of FIG. 3, the evaporator 38 may include a tube bundle 58 having a supply line 60S and a return line 60R connected to a cooling load 62. The cooling fluid of the evaporator 38 (e.g., water, ethylene glycol, calcium chloride brine, sodium chloride brine, or any other suitable fluid) enters the evaporator 38 via return line 60R and exits the evaporator 38 via supply line 60S. The evaporator 38 may reduce the temperature of the cooling fluid in the tube bundle 58 via thermal heat transfer with the working fluid. The tube bundle 58 in the evaporator 38 can include a plurality of tubes and/or a plurality of tube bundles. In any case, the vapor working fluid exits the evaporator 38 and returns to the compressor 32 by a suction line to complete the cycle.

[0030] FIG. 4 is a schematic of the vapor compression system 14 with an intermediate circuit 64 incorporated between condenser 34 and the expansion device 36. The intermediate circuit 64 may have an inlet line 68 that is directly fluidly connected to the condenser 34. In other embodiments, the inlet line 68 may be indirectly fluidly coupled to the condenser 34. As shown in the illustrated embodiment of FIG. 4, the inlet line 68 includes a first expansion device 66 positioned upstream of an intermediate vessel 70. In some embodiments, the intermediate vessel 70 may be a flash tank (e.g., a flash intercooler, an economizer, etc.). In other embodiments, the intermediate vessel 70 may be configured as a heat exchanger or a “surface economizer.” In the illustrated embodiment of FIG. 4, the intermediate vessel 70 is used as a flash tank, and the first expansion device 66 is configured to lower the pressure of (e.g., expand) the liquid working fluid received from the condenser 34. During the expansion process, a portion of the liquid may vaporize, and thus, the intermediate vessel 70 may be used to separate the vapor from the liquid received from the first expansion device 66.

[0031] Additionally, the intermediate vessel 70 may provide for further expansion of the liquid working fluid due to a pressure drop experienced by the liquid working fluid when entering the intermediate vessel 70 (e.g., due to a rapid increase in volume experienced when entering the intermediate vessel 70). The vapor in the intermediate vessel 70 may be drawn by the compressor 32 through a suction line 74 of the compressor 32. In other embodiments, the vapor in the intermediate vessel may be drawn to an intermediate stage of the compressor 32 (e.g., not the suction stage). The liquid that collects in the intermediate vessel 70 may be at a lower enthalpy than the liquid working fluid exiting the condenser 34 due to the expansion in the expansion device 66 and/or the intermediate vessel 70. The liquid from intermediate vessel 70 may then flow in line 72 through a second expansion device 36 to the evaporator 38.

[0032] It should be appreciated that any of the HVAC&R systems discussed above may be utilized in accordance with the present techniques. For example, the present techniques may incorporate embodiments of the HVAC&R system 10, the vapor compression system 14, the boiler 16, a chiller, a heat pump, and/or other HVAC&R equipment discussed above. As briefly discussed above, present embodiments are directed to embodiments of the HVAC&R system 10, which may include a heat pump configured to be incorporated with a distillation system (e.g., distillation operation). In particular, as discussed herein, the heat pump may include a heat storage system configured to extract and store excess heat (e.g., rejected heat, as a heated fluid) to enable the heat pump to more efficiently and/or effectively satisfy (e.g., match) the varying target heating and/or cooling loads of stages or operations of the distillation process. In addition, the heat storage system may be configured to enable use of the stored heat in desired stages of the distillation process, such as sanitizing (e.g., cleaning) components of the distillation system (e.g., the distillation vessel) between batch processes and/or for pre-heating the components of the distillation system (e.g., during initiation of a new batch process). In this way, the heat storage system of the heat pump system may further increase the efficiency (e.g., energy efficiency) and the cost effectiveness of the distillation process by capturing and storing the excess heat when the target heating load of the distillation process is lower than the heating load (e.g.., heating output, heating capacity) of the heat pump system, and by using the stored heat (e.g., excess heat, rejected heat) in distillation stages when a target heating demand of the distillation process is higher than the heating output of the heat pump system (e.g., working fluid circuit).

[0033] It should be appreciated that the present systems and techniques, as applied to distillation processes, may be incorporated with or configured to operate with other processes including, but not limited to, evaporation-concentration systems or processes, vacuum and/or rotary evapo-concentration systems or processes, desalination systems or processes, water distillation systems or processes, water purification systems or processes, systems or processes for distilling and/or concentrating a mixture or liquid, and the like. For example, a heat pump system and/or a heat storage system may be configured to efficiently and effectively satisfy (e.g., correlate, match) heating and/or cooling loads associated with evaporation-concentration systems or processes. The evaporation concentration systems may be used to separate contaminates (e.g., impurities, pollutants, debris, solvent) from a liquid substance or mixture. In such processes, heat may be used or applied to a mixture containing the contaminates (e.g., under vacuum) to vaporize the liquid and separate out the contaminates from the mixture. The contaminates may be removed, leaving a more purified (e.g., more concentrated) liquid substance. For desalination and/or water distillation systems or processes, a heat pump system and/or heat storage system may be incorporated with or configured to operate with the foregoing systems or processes to provide heat to vaporize or distill a water mixture to remove any impurities (e.g., pollutants, debris, contaminates, salts, etc.) within the water mixture, leaving a more purified or more concentrated water product. Thus, present systems and techniques may increase the efficiency (e.g., energy efficiency) and the cost effectiveness of various industrial processes, such as evaporation-concentration systems or processes, vacuum and/or rotary evapo-concentration systems or processes, desalination systems or processes, water distillation systems or processes, water purification systems or processes, systems or processes for distilling and/or concentrating a mixture or liquid, and the like, by capturing and storing (e.g., via the heat storage system) the excess heat when the target heating load of the industrial processes is lower than the heating load (e.g.., heating output, heating capacity) of the heat pump system, and by using the stored heat (e.g., excess heat, rejected heat) in various stages of these industrial processes when a target heating demand of the industrial processes is higher than the heating output of the heat pump system (e.g., working fluid circuit).

[0034] With the foregoing in mind, FIGS. 5 and 6 are schematics of embodiments of the HVAC&R system 10 including a heat pump system 100 incorporated with a distillation system 102 (e.g., distillation operation, distillation process). In particular, FIG. 5 illustrates the heat pump system 100 as being configured to receive, as indicated by arrow 104, a first fluid flow (e.g., water and alcohol mixture, a conditioning fluid) from a distillation vessel 106 (e.g., distillation column, vessel, evaporation-concentration vessel, tank, desalination vessel, water distillation vessel) of the distillation system 102. The heat pump system 100 is also configured to heat the first fluid flow and supply, as indicated by arrow 108, a heated and/or vaporized first fluid flow (e.g., steam, heated water and alcohol mixture) to the distillation vessel 106. Furthermore, the heat pump system 100 is configured to receive, as indicated by arrow 110, a second fluid flow (e.g., alcohol vapor, a conditioning fluid) from the distillation vessel 106 of the HVAC&R system 10 and to cool (e.g., condense) the second fluid flow. The heat pump system 100 may then supply, as indicated by arrow 114, a cooled second fluid flow to the distillation vessel 106. The distillation vessel 106 of the distillation system 102 may receive a first process fluid flow (e.g., mixture of water and alcohol), as indicated by arrow 122, and through a distillation process within the distillation vessel 106 (e.g., utilizing the heat pump system 100), supply a second process fluid flow (e.g., product, more concentrated alcohol), as indicated by arrow 124. [0035] The illustrated embodiment of the heat pump system 100 is a closed (e.g., closed loop) heat pump system 120 incorporated with the distillation system 102. The closed heap pump system 120 may include at least a vapor compression circuit 126 having a first heat exchanger 128 (e.g., an evaporator, operating as an evaporator), a second heat exchanger 130 (e.g., a condenser, operating as a condenser), a compressor 132, and an expansion valve 134. The closed heat pump system 120 (e.g., the vapor compression circuit 126) is configured to circulate a working fluid (e.g., a refrigerant, water) to cool and/or heat one or more fluids (e.g., first fluid flow, second fluid flow, water, water and alcohol mixture, alcohol vapor), such as fluids and/or fluid mixtures received from the distillation vessel 106. In particular, the first heat exchanger 128 and the second heat exchanger 130 may each be configured to receive the working fluid and a respective flow of fluid and to place the working fluid in the heat exchange relationship with the respective flow of fluid. For example, the first heat exchanger 128 (e.g., evaporator) may receive, as indicated by arrow 110, the second fluid flow (e.g., a flow of fluid, a flow of alcohol vapor, partially condensed alcohol vapor) from the distillation vessel 106 of the HVAC&R system 10 and may place the second fluid flow in a heat exchange relationship with the working fluid. In this way, heat (e.g., thermal energy) may be transferred from the second fluid flow to the working fluid to condense the second fluid flow (e.g., condense the alcohol vapor). The first heat exchanger 128 may then supply and/or return, as indicated by arrow 114, the condensed second fluid flow to the distillation vessel 106. In addition, the second heat exchanger 130 (e.g., condenser) may receive, as indicated by arrow 104, the first fluid flow (e.g., a flow of fluid, a flow of water or water and alcohol mixture) from the distillation vessel 106 of the distillation system 102. The second heat exchanger 130 may place the first fluid flow in a heat exchange relationship with the working fluid. In this way, heat (e.g., thermal energy) may be transferred from the working fluid to the first fluid flow to generate vaporized first fluid flow (e.g., vaporized water and/or vaporized alcohol) and/or a heated first fluid flow (e.g., heated water and alcohol mixture.) The second heat exchanger 130 may then supply, as indicated by arrow 108, the heated and/or vaporized first fluid flow to the distillation vessel 106. [0036] The closed heat pump system 120 may operate in a closed loop (e.g., closed circuit, closed flow) configuration, such that the closed heat pump system 120 may circulate a fixed or constant volume of the working fluid (e.g., water). In addition, the working fluid of the closed heat pump system 120 may not mix with and/or contact fluid (e g., fluid mixture) within the distillation vessel 106 of the distillation system 102. In this way, the working fluid of the closed heat pump system 120 may be a different fluid or may be the same fluid as the fluid within the distillation vessel 106. For example, in some embodiments, the working fluid of the closed heat pump system 120 may be water. In other embodiments, the working fluid (e.g., refrigerant) may be a hydrofluorocarbon (HFC) based working fluid, such as R-410A, R-407, R-134a, hydrofluoro olefin (HFO) based refrigerant, such as R-1234ze, R1233zd, a "natural" working fluid, such as ammonia (NH3), R-717 or carbon dioxide (CO2), R-744, or any other suitable working fluid. The fluid within the distillation vessel 106 and circulated through the first heat exchanger 128 and the second heat exchanger 130 may be any suitable fluid, such as water, a water and alcohol mixture, a fluid to be distilled or concentrated via a distillation process (e.g., evapo- concentration process, desalination process, water distillation process), or any combination thereof.

[0037] FIG. 6 illustrates an embodiment of the heat pump system 100 configured as an open (e.g., open loop) heat pump system 140, in accordance with the present techniques. The open heat pump system 140 may include at least a portion of a vapor compression circuit 142 having a heat exchanger 144 (e.g., an evaporator), a compressor 146, and an expansion valve 148. The open heat pump system 140 (e.g., the vapor compression circuit 142) is configured to circulate a working fluid (e.g., water, water and alcohol mixture) to cool and/or heat one or more fluids (e.g., distillation process fluids, water, water and alcohol mixture), such as fluids and/or fluid mixtures received from the distillation vessel 106. In particular, the heat exchanger 144 may be configured to receive a flow of the working fluid and a first fluid flow from the distillation vessel 106 and to place the working fluid in a heat exchange relationship with the first flow of fluid. For example, the heat exchanger 144 (e.g., evaporator) may receive, as indicated by arrow 110, the first fluid flow (e.g., alcohol vapor, vaporized alcohol and water mixture) from the distillation vessel 106 of the HVAC&R system 10 and place the first fluid flow in a heat exchange relationship with the working fluid. In this way, heat (e.g., thermal energy) may be transferred from the first fluid flow to the working fluid to cool (e.g., condense) the first fluid flow. The heat exchanger 144 may then supply and/or return, as indicated by arrow 114, the condensed first fluid flow to the distillation vessel 106.

[0038] In addition, the open heat pump system 140 may receive, as indicated by arrow 104, a second fluid flow (e.g., water, a water and alcohol mixture, working fluid) from the distillation vessel 106 of the distillation system 102. The open heat pump system 140 may circulate the second fluid flow through the expansion valve 148, the heat exchanger 144, and the compressor 146 to heat (e.g., increase thermal energy) the second fluid flow to generate vaporized second fluid flow (e.g., steam and/or vaporized water and alcohol mixture.) The open heat pump system 140 may circulate the second fluid flow through the heat exchanger 144 as the working fluid described above. In other words, the open heat pump system 140 may circulate the second fluid flow through the heat exchanger 144 (e.g., evaporator) to enable transfer of heat from the first fluid (e.g., alcohol vapor) to the second fluid flow (e.g., the water or water and alcohol mixture). The compressor 146 may then supply, as indicated by arrow 108, the heated and/or vaporized second fluid flow (e.g., heated and/or vaporized water or water and alcohol mixture, steam) to the distillation vessel 106.

[0039] The open heat pump system 140 may operate in an open loop (e.g., open circuit, open flow) configuration. That is, the open heat pump system 140 may circulate the second fluid flow (e.g., water, water and alcohol mixture) received from the distillation vessel 106 (e.g., as a working fluid) and may place the second fluid flow in a heat exchange relationship with the first fluid flow (e.g., alcohol vapor) to condense the first fluid flow, whereby the first fluid flow and the second fluid flow are both directed to the open heat pump system 140 from the distillation vessel 106. In particular, the working fluid (e.g., the second fluid flow) and the distillation fluid (e.g., the first fluid flow) may both originate from the same fluid (e.g., the distillation process fluid, the received first process fluid (arrow 122)). The open heat pump system 140 configuration may be beneficial, for example, by virtue of the simplification in circulating different flows of fluid from the distillation vessel 106 and enabling heat exchange therebetween to facilitate a distillation process.

[0040] As discussed herein, loads (e.g., heating loads, cooling loads, heating demands, cooling demands) for certain stages (e.g., steps, operations, batch stages) of distillation processes of a distillation system may vary. In addition, outputs (e.g., heating outputs, cooling outputs) of existing heat pump systems may vary and/or not correlate (e.g., match, satisfy) with the varying loads associated with the distillation processes. As such, existing heat pump systems integrated or incorporated with distillation systems may cause inefficiencies during operation of the distillation systems. In particular, a heating output or capacity of a heat pump system may be higher or lower than a target heating load (e.g., heating demand) of one or more of the distillation stages. For example, if a heating output or capacity of the heat pump system is lower than a heating demand of a distillation stage, such as an initial start-up stage (e g., between distillation batches), a pressure of a fluid from the distillation system that is circulated through the heat pump system (e.g., water, water and alcohol mixture, second fluid flow) may decrease, which may cause a vaporizing temperature of the fluid to be lower than a target vaporizing temperature. In addition, in some instances, if a heating output or capacity of the heat pump system is higher than a heating demand of a distillation stage, such as may occur during regular distillation operations, a pressure of the fluid circulated from the distillation system may increase, which may cause a vaporizing temperature of the fluid to be higher than a target vaporizing temperature. In other words, excess heat may be produced due to a heating output of the heat pump system being higher than a heating demand of a distillation stage. Therefore, improved heat pump systems that may more efficiently and/or effectively satisfy (e.g., match, correlate) the varying heating and/or cooling loads of the distillation system are desired. [0041] With the foregoing in mind, FIG. 7 is a schematic of an embodiment of the HVAC&R system 10 including the heat pump system 100 incorporated with the distillation system 102. The heat pump system 100 also includes a heat storage system 150. In particular, the heat storage system 150 is integrated with an embodiment of the heat pump system 100 configured as a closed heat pump system 160 (e.g., closed heat pump system 120) incorporated with the distillation system 102. The heat storage system 150 is configured to collect and store excess heat (e.g., rejected heat, as a heated fluid) to enable the heat pump system 100 (e.g., closed heat pump system 160) to more efficiently and/or effectively satisfy (e.g., match, correlate) the varying target heating and/or cooling demands of stages of the distillation system 102. In addition, the heat storage system 150 may be configured to enable the stored heat to be used in various stages, operations, and/or processes of the distillation system 102, such as sanitizing (e.g., cleaning) components of the distillation system 102 (e.g., the distillation vessel 106) between distillation batches (e.g., between normal distillation operations) and/or for pre-heating components of the distillation system 102 (e.g., the distillation vessel 106, pipes/conduits/plumbing, heat exchangers 154, 156, and/or 174, compressor 158, for example, during initiation of a new distillation batch). To this end, the heat storage system 150 may store a heated fluid that is generated via operation of the heat pump system 100. In some embodiments, the stored heat (e.g., stored heated fluid) may be used in other processes, and/or another process or operation of the HVAC&R system 10. In this way, the heat storage system 150 of the heat pump system 100 may increase the efficiency (e.g., energy efficiency) and cost effectiveness of the distillation system 102 by capturing and storing the excess heat (e.g., rejected heat) when a target heating load or heating demand of the distillation system 102 is lower than a heating output or capacity of the heat pump system 100. The heat storage system 150 also enables use of the stored heat (e.g., excess heat) during stages, operations, and/or processes (e.g., distillation stages) when a heating demand of the distillation system 102 is higher than a heating output of the heat pump system 100. Accordingly, present embodiments enable increased efficiency and reduced energy consumption while also enabling satisfaction of varying loads on the heat pump system 100 and various processes associated with the heat p ump system 100 and/or the distillation system 102.

[0042] Continuing with FIG. 7, the closed heat pump system 160 may include a vapor compression circuit 152 including at least a first heat exchanger 154 (e.g., an evaporator 154), a second heat exchanger 156 (e.g., a condenser 156), a compressor 158, and an expansion valve 162. The closed heat pump system 160 (e.g., the vapor compression circuit 152) is configured to circulate a working fluid (e.g., water) to cool and/or heat one or more fluids (e.g., first fluid flow, second fluid flow, water, water and alcohol mixture, alcohol vapor), such as fluids and/or fluid mixtures received from the distillation vessel 106. In particular, the first heat exchanger 154 and the second heat exchanger 156 may each be configured to receive a respective flow of the working fluid and a respective flow of fluid from the distillation vessel 106 and to place the working fluid in a heat exchange relationship with the respective flow of fluid. For example, the first heat exchanger 154 may receive, as indicated by arrow 164, alcohol vapor from the distillation vessel 106 of the distillation system 102 and place the alcohol vapor in a heat exchange relationship with the working fluid. In this way, heat (e.g., thermal energy) may be transferred from the alcohol vapor to the working fluid to further cool and/or condense the alcohol vapor. The first heat exchanger 154 (e.g., evaporator) may then supply and/or return, as indicated by arrow 166, the condensed alcohol to the distillation vessel 106.

[0043] In addition, the second heat exchanger 156 (e.g., condenser) may receive, as indicated by arrow 168, a flow of water or a water and alcohol mixture from the distillation vessel 106 of the distillation system 102 and place the flow of water or water and alcohol mixture in a heat exchange relationship with the working fluid. In this way, heat (e.g., thermal energy) may be transferred from the working fluid to the water or water and alcohol mixture to generate steam and/or vaporize the water and alcohol mixture. The second heat exchanger 156 may then supply, as indicated by arrow 170, the heated and/or vaporized water or water and alcohol mixture (e.g., steam) to the distillation vessel 106. [0044] The closed heat pump system 160 may operate in a closed loop (e.g., closed circuit, closed flow) configuration. That is, the closed heat pump system 160 may circulate a fixed or constant volume of the working fluid. In addition, the working fluid of the closed heat pump system 160 may not mix with and/or contact the fluid (e.g., fluid mixture) of the distillation vessel 106 of the distillation system 102. In this way, the working fluid of the closed heat pump system 160 may be a different fluid or may be the same fluid as the fluid or fluid mixture within the distillation vessel 106. For example, in some embodiments, the working fluid of the closed heat pump system 160 may be water. In other embodiments, the working fluid may be a hydrofluorocarbon (HFC) based working fluid, for example, R-410A, R-407, R-134a, hydrofluoro olefin (HFO) based working fluid, for example, R-1234ze, R1233zd, a "natural" working fluid, such as ammonia (NH3), R- 717, carbon dioxide (CO2), R-744, or any other suitable working fluid. The fluid within the distillation vessel 106 and circulated through the first heat exchanger 154 and the second heat exchanger 156 may be any suitable fluid, such as water, a water and alcohol mixture, a fluid to be distilled or concentrated via a distillation process (e.g., evapo- concentration process, desalination process, water distillation process), or any combination thereof.

[0045] In addition, the HVAC&R system 10 includes the heat storage system 150 coupled (e.g., thermally coupled, fluidly coupled to) to the closed heat pump system 160 incorporated with the distillation system 102. Further, the heat storage system 150 may also be fluidly coupled to the distillation system 102, in some embodiments. The heat storage system 150 includes a heat exchanger 172 (e.g., plate heat exchanger) and a heat storage vessel 174 (e.g., tank, container). In particular, the heat storage vessel 174 may contain (e.g., store) a heat storage fluid (e.g. water, heated fluid, storage fluid) that may enable the heat storage system 150 to receive and store excess heat from the closed heat pump system 160. For example, the heat exchanger 172 may receive at least a portion of a flow of the working fluid from the compressor 158 (e g., discharged from the compressor, before the flow of the working fluid is directed to the second heat exchanger 156, downstream of a discharge port of the compressor 158). The heat exchanger 172 may also receive a flow of heat storage fluid (e.g., water, storage fluid) from an external source 178 (e.g., a utility water source, ground water source) and may place the working fluid in a heat exchange relationship with the heat storage fluid received via the external source 178. In this way, heat (e.g., thermal energy) may be transferred from the working fluid of the closed heat pump system 160 to the heat storage fluid of the heat storage vessel 174. In some embodiments, the flow of heat storage fluid may be received by the heat exchanger 172 from the heat storage system 150 (e.g., from the heat storage vessel 174). As such, a thermal energy (e.g., heat) of the heat storage fluid may progressively increase during operation of the closed heat pump system 160 and the heat storage system 150. In some embodiments, the flow of heat storage fluid received by the heat exchanger 172 may be a combination of a flow of fluid from the heat storage vessel 174 and a flow of fluid from the external source 178.

[0046] A flow (e.g., an amount) of the working fluid directed to the heat exchanger 172 of the heat storage system 150 (e.g., from the compressor 158, downstream of the compressor 158) may be controlled (e.g., adjusted), such as via a valve 176. In some embodiments, the amount of working fluid flow directed towards the heat exchanger 172 may be controlled (e.g., via a controller, control system 250) based on a temperature and/or pressure (e.g., detected by a sensor communicatively coupled to the controller, sensor 252) of one or more fluids (e.g., water, alcohol, water and alcohol mixture) of the distillation system 102 (e.g., within the distillation vessel 106, circulated from the distillation vessel 106 to the heat pump system 100), a stage of the distillation process of the distillation system 102, a temperature and/or pressure of the working fluid of the closed heat pump system 160, another suitable operating parameter, or any combination thereof.

[0047] Further, a flow (e.g., an amount) of the heat storage fluid received via the external source 178 and directed to the heat exchanger 172 of the heat storage system 150 may be controlled (e.g., adjusted), such as via a valve 180. In particular, a position of the valve 180 may be controllably adjusted (e.g., via a controller, control system 250) to adjust the amount of heat storage fluid received by and/or directed to the heat exchanger 172. The amount of heat storage fluid received via the external source 178 (e.g., received by the heat exchanger 172) and/or a position of the valve 180 may be controlled (e g., by a controller, control system 250) based on one or more operating parameters of the heat pump system 100 and/or the distillation system 102, such as an amount of superheat (e.g., 2 Kelvin [K], 4 K, 3 K, 2 to 4 K) and/or a temperature of fluid (e.g., the heat storage fluid, detected by a sensor, sensor 252) output by the heat exchanger 172 (e.g., received by the heat storage vessel 174). In particular, an increase in a valve opening of the valve 180 (e.g., increased flow of received heat storage fluid from the external source 178) may cause a decrease in the amount of superheat of the vaporized fluid output by the heat exchanger 172. In such instances, an amount of vaporized fluid (e.g., vaporized fluid mass) may decrease, and an amount of liquid fluid flow (e.g., liquid fluid mass) may increase. On the other hand, in response to a decrease in the valve opening of the valve 180 (e.g., decrease in flow of received heat storage fluid from the external source 178), the amount of vaporized fluid flow may increase and the amount of liquid fluid flow may decrease.

[0048] To controllably actuate the valve 176 and/or the valve 180, the HVAC&R system 10 may include a control system 250 (e.g., a controller, an automation controller, an electronic controller, a programmable controller, a valve controller, a cloud-computing device, control circuitry) communicatively coupled to and configured to operate the valve 176, the valve 180, or both to regulate or adjust a respective opening (e.g., position) of the valve 176, the valve 180, or both. In this way, the control system 250 may be configured to adjust an amount (e.g., flow rate, volume) of fluid through the respective valves (e.g., valve openings.) In particular, as discussed herein, the control system 250 is configured to control or adjust an amount of working fluid directed from the vapor compression circuit 152 to the heat exchanger 172 (e.g., downstream of the compressor 158) by controllably adjusting an opening or position of the valve 176. To this end, the control system 250 may be communicatively coupled to one or more sensors 252. The one or more sensors 252 may be configured to detect a temperature and/or pressure of fluid within the HVAC&R system 10. [0049] In particular, the sensor 252 may detect a temperature and/or pressure of fluid (e.g., working fluid) within the closed heat pump system 160 and the control system 250 may receive the detected temperature and/or pressure of fluid from the sensor 252 as sensor data. Furthermore, the control system 250 may compare the detected temperature and/or pressure of the fluid to one or more thresholds, heating or cooling demands or loads of the distillation system 102, or the like. In addition, the control system 250 may controllably adjust the valve 176 based on the comparison. For example, the control system 250 may determine that the detected temperature and/or pressure of the working fluid of the closed heat pump system 160 is greater than a threshold or greater than a heating demand of the distillation system 102. The control system 250 may adjust the valve 176, based on or in response to determining that the temperature and/or pressure of the fluid is greater than the threshold or greater than the heating demand, to increase an amount of working fluid directed towards the heat exchanger 172. In this way, the control system 250 may enable the HVAC&R system 10 to off-load, reduce, an/or store excess heat from the closed heat pump system 160, and transfer (e.g., collect) the excess heat from the working fluid to the heat storage fluid (e g., via the heat exchanger 172.) Thus, the HVAC&R system 10 may enable the close heat pump system 160 to efficiently and effectively match (e.g., correlate) heating and/or cooling demands or loads of the distillation system 102.

[0050] In a similar way, the control system 250 is configured to control or adjust an amount of heat storage fluid directed from the external source 178 to the heat exchanger 172 by controllably adjusting an opening or position of the valve 180. To this end, the sensor 252 may detect a temperature and/or pressure of fluid (e.g., superheat of the heat storage fluid) output by the heat exchanger 172 (e.g., received by the heat storage vessel 174) and the control system 250 may receive the detected temperature and/or pressure of fluid from the sensor 252 as sensor data. Furthermore, the control system 250 may compare the detected temperature and/or pressure of the fluid to one or more thresholds. In addition, the control system 250 may controllably adjust the valve 180 based on the comparison. For example, the control system 250 may determine that the detected temperature and/or pressure of the heat storage fluid output by the heat exchanger 172 of is greater than a threshold temperature and/or pressure. The control system 250 may adjust the valve 180, based on or in response to determining that the temperature and/or pressure of the fluid is greater than the threshold, to increase an amount of heat storage fluid directed towards the heat exchanger 172 (e.g., from the external source 178). In this way, the control system 250 may enable the HVAC&R system 10 to maintain a consistent or desired ratio of an amount of vaporized heat storage fluid flow (e.g., vaporized fluid mass) and an amount of liquid heat storage fluid flow (e.g., liquid fluid mass) stored in the heat storage vessel 174. Thus, the HVAC&R system 10 may enable the heat storage system 150 to efficiently and effectively maintain a desired ratio of vaporized form versus liquid form of the heat storage fluid flow.

[0051] The control system 250 may include a memory 254 and processing circuitry 256 (e g., a microprocessor, one or more processors, processor). The memory 254 may include volatile memory, such as random-access memory (RAM), and/or non-volatile memory, such as read-only memory (ROM), optical drives, hard disc drives, solid-state drives, or any other non-transitory computer-readable medium storing instructions that, when executed, control operation of the valve 176, the valve 180, or both. The processing circuitry 256 may be configured to execute such instructions. As an example, the processing circuitry 256 may include one or more application specific integrated circuits (ASICs), one or more field programmable gate arrays (FPGAs), one or more general purpose processors, or any combination thereof.

[0052] The one or more sensors 252 may be configured to transmit an indication of a fluid parameter, such as temperature, volume, pressure, and/or flow rate, of the fluid within the HVAC&R system 10 to the control system 250. In some embodiments, the one or more sensors 252 may be configured to transmit the indication when a monitored value of a fluid parameter falls outside of a desired range of values, is above a threshold, is below a threshold, or any combination thereof. For example, when the one or more sensors 250 detects that a fluid parameter value is below a threshold value (e.g., lower limit of the desired range of values) and/or detects that an operational condition value is above a threshold value (e.g., upper limit of the desired range of values), the one or more sensors 250 may be configured to transmit the fluid parameter valve, and indication of the fluid parameter value being outside the desired range, or both to the control system 250. In either case, the control system 250 may be configured to transmit control signals to the valve 176, the valve 180, or both, to adjust an amount of fluid flow through the respective valve based on the received data and/or indication.

[0053] In some embodiments, the one or more sensors 252 may be temperature sensors configured to detect a temperature associated with the HVAC&R system 10, such as a temperature of the working fluid at particular points within the vapor compression circuit 152, the distillation system 102, and/or the heat storage system 150. For example, the one or more sensors 252 may detect a compressor discharge temperature, an evaporator discharge temperature, a heat exchanger discharge temperature, a heat storage vessel temperature, an intermediate vessel discharge temperature, and/or a suction inlet temperature. Additionally or alternatively, the one or more sensors 252 may be pressure sensors configured to detect a pressure of the working fluid at particular points within the vapor compression circuit 152, the distillation system 102, and/or the heat storage system 150. For example, the one or more sensors 252 may detect a compressor discharge pressure, an evaporator discharge pressure, a heat exchanger discharge pressure, a heat storage vessel pressure, an intermediate vessel discharge pressure, and/or a suction inlet pressure.

[0054] Furthermore, the heat storage vessel 174 may be fluidly coupled to one or more components of the distillation system 102 and/or the closed heat pump system 160. For example, in some embodiments, the heat storage vessel 174 may be fluidly coupled to the distillation vessel 106 and be configured to direct a portion of the heated storage fluid (e.g., heated water) to the distillation vessel 106. For example, the HVAC&R system 10 may include one or more additional valves 258 configured to adjust or control an amount of heat storage fluid directed to the one or more components. In particular, the control system 250 may be communicatively coupled to the one or more additional valves 258 and configured to adjust a respective position or opening of the one or more additional valves 258. In this way, the control system 250 is configured to control an amount of the heat storage fluid directed to the one or more components. In some embodiments, the control system 250, may adjust one or more of the additional valves 258 based on data or feedback from a sensor (e.g., one or more sensors 252, temperature sensor, pressure sensor, volume or flow rate sensor), based on an indication of a new batch and/or initiation (e.g., start-up operation) of the distillation process, based on indication of a cleaning, sanitizing, or preparation operations, based on received user input (e.g., from an operator of the distillation system 102), or any combination thereof.

[0055] In this way, as discussed herein, the stored heat (e.g., captured and stored via the heat storage system 150) may be used to provide additional heat (e.g., as a heated fluid) to the distillation vessel 106 (e.g., pre-heat the distillation vessel 106 and/or conduits of the HVAC&R system 10) prior to initiation of a new distillation batch, during initiation process of a new distillation batch, in between distillation batches, for cleaning and/or sanitizing the distillation vessel 106, or any combination thereof. Similarly, in some embodiments, a portion of the heated storage fluid (e.g., heated water) may be directed towards the first heat exchanger 154, the second heat exchanger 156, the compressor 158, or any combination thereof, to provide additional heat to heat and/or pre-heat the first heat exchanger 154, the second heat exchanger 156, and/or the compressor 158, such as prior to initiation of a new distillation batch, in between distillation batches, for cleaning and/or sanitizing the first heat exchanger 154, the second heat exchanger 156, and/or the compressor 158, or any combination thereof. For example, the heated storage fluid may be used to provide heat to the distillation process fluid (e.g., water and/or alcohol mixture of the distillation system 102) and/or to the working fluid (e.g., of the heat pump system 160) of the first and/or second heat exchangers 154, 156. In some embodiments, one or more additional heat exchangers may be used in parallel to the first and/or second heat exchangers 154, 156 to transfer heat from the heated storage fluid to the process fluid and/or the working fluid of the respective first and/or second heat exchangers 154, 156. [0056] FIG. 8 is a schematic of an embodiment of the HVAC&R system 10 including the heat pump system 100 incorporated with the distillation system 102. The HVAC&R system 10 also includes a heat storage system 181. In the illustrated embodiment, the heat storage system 181 is integrated with an embodiment of the heat pump system 100 configured as an open heat pump system 190 (e.g., open heat pump system 140) incorporated with the distillation system 102. The heat storage system 181 is configured to store excess heat (e.g., rejected heat) to enable the heat pump system 100 (e.g., open heat pump system 190) to more efficiently and/or effectively satisfy (e.g., match, correlate) the varying target heating and/or cooling demands of stages of the distillation system 102. In addition, the heat storage system 181 may be configured to enable the stored heat (e.g., stored heated fluid) to be used in various stages of the distillation system 102, such as sanitizing (e.g., cleaning) components of the distillation system 102 (e.g., the distillation vessel 106) between distillation batches, during initiation processes of a new distillation batch, and/or for pre-heating components of the distillation system 102 (e.g., the distillation vessel 106, pipes/conduits/plumbing, heat exchanger 184, compressor 186, during initiation of a new batch). In this way, the heat storage system 181 of the heat pump system 100 may increase the efficiency (e.g., energy efficiency) and the cost effectiveness of the distillation system 102 by capturing and storing the excess heat when a target heating load or a heating demand of the distillation system 102 is lower than a heating output of the heat pump system 100. The heat storage system 181 also enables use of the stored heat (e.g., excess heat) during stages, operations, and/or processes (e.g., distillation stages) when a heating demand of the distillation system 102 is higher than a heating output of the heat pump system 100.

[0057] Continuing with FIG. 8, the open heat pump system 190 may include a portion of a vapor compression circuit 182 having a heat exchanger 184 (e.g., an evaporator 184), a compressor 186, and an expansion valve 188. The open heat pump system 190 (e.g., the vapor compression circuit 182) is configured to circulate a working fluid (e g., water, water and alcohol mixture) to cool and/or heat one or more fluids (e.g., water, water and alcohol mixture), such as fluids and/or fluid mixtures received from the distillation vessel 106. In particular, the heat exchanger 184 may be configured to receive a first fluid flow from the distillation vessel 106 and a second fluid flow from the distillation vessel 106 and to place the first fluid flow in a heat exchange relationship with the second fluid flow. For example, the heat exchanger 184 (e.g., evaporator) may receive, as indicated by arrow 192, the first fluid flow (e.g., a flow of alcohol vapor) from the distillation vessel 106 of the HVAC&R system 10 and place the first fluid flow in a heat exchange relationship with the second fluid flow (e.g., working fluid, water or water and alcohol mixture) received from the distillation vessel 106 (e.g., via the portion of the vapor compression circuit 182.) In this way, heat (e.g., thermal energy) may be transferred from the first fluid flow to the second fluid flow to cool and condense the first fluid flow. The heat exchanger 184 may then supply and/or return, as indicated by arrow 194, the condensed first fluid flow to the distillation vessel 106. In addition, the open heat pump system 190 may receive, as indicated by arrow 196, the second fluid flow (e.g., water or water and alcohol mixture) from the distillation vessel 106 of the distillation system 102. In particular, the open heat pump system 190 may circulate the second fluid flow (e.g., water or water and alcohol mixture) through the expansion valve 188, the heat exchanger 184, and the compressor 186 to heat (e.g., increase thermal energy) the second fluid flow and generate a vaporized second fluid flow (e.g., steam and/or vaporize the water and alcohol mixture.) The compressor 186 may then supply, as indicated by arrow 198, the heated and/or vaporized second fluid flow to the distillation vessel 106.

[0058] The open heat pump system 190 may operate in an open loop (e.g., open circuit, open flow) configuration. That is, the open heat pump system 190 may circulate the second fluid flow (e.g., water, water and alcohol mixture) received from the distillation vessel 106 (e.g., the distillation system 102) and may place the second fluid flow in a heat exchange relationship with the first fluid flow (e.g., vapor alcohol) received from distillation vessel 106. In this way, first fluid flow and second fluid flow circulated through the open heat pump system 190 (e.g., through at least one component of the open heat pump system 190) may both be received from the distillation vessel 106. In particular, the working fluid (e.g., the second fluid flow) and the distillation fluid (e.g., the first fluid flow) may both originate from the same fluid (e.g., the distillation process fluid, the received first process fluid, as indicated by arrow 122). The open heat pump system 190 configuration may be beneficial, for example, by virtue of the simplification in circulating different flows of fluid from the distillation vessel 106 and enabling heat exchange therebetween to facilitate a distillation process.

[0059] In addition, the HVAC&R system 10 includes the heat storage system 181 coupled (e.g., thermally coupled, fluidly coupled to) to the open heat pump system 190 incorporated with the distillation system 102. Further, the heat storage system 181 may also be fluidly coupled to the distillation system 102. The heat storage system 181 includes a heat exchanger 200 (e.g., plate heat exchanger) and a heat storage vessel 202 (e.g., container, tank). In particular, the heat storage vessel 202 may contain (e.g., store) a heat storage fluid, such as water, that may enable the heat storage system 181 to receive and store excess heat from the open heat pump system 190. For example, the heat exchanger 200 may receive a portion of the second fluid flow from the compressor 186 (e.g., discharged from compressor, before the flow is directed to the distillation vessel 106, downstream of a discharge port of the compressor 186). The heat exchanger 200 may also receive a flow of heat storage fluid from an external source 206 (e.g., a utility water source and/or ground water source) and may place the second fluid flow in a heat exchange relationship with the heat storage fluid received via the external source 206. In this way, heat (e.g., thermal energy) may be transferred from the second fluid flow(e.g., working fluid of the open heat pump system 190) to the heat storage fluid that is directed to the heat storage vessel 202. In some embodiments, the flow of heat storage fluid may be received by the heat exchanger 200 from the heat storage system 181 (e.g., from the heat storage vessel 202). As such, a thermal energy (e.g., heat) of the heat storage fluid may progressively increase during operation of the open heat pump system 190 and the heat storage system 181. In some embodiments, the flow of heat storage fluid received by the heat exchanger 200 may be a combination of a flow of fluid from the heat storage vessel 202 and a flow of fluid from the external source 206. [0060] A flow (e.g., an amount) of the second fluid flow directed to the heat exchanger 200 of the heat storage system 181 (e.g., from the compressor 186, downstream of the compressor 186) may be controlled (e.g., adjusted), such as via a valve 204. Furthermore, the amount of the second flow of fluid directed towards the heat exchanger 200 may be controlled (e.g., via a controller, control system 250) based on a temperature and/or pressure (e.g., detected by a sensor communicatively coupled to the controller, one or more sensors 252) of one or more fluids (e.g., water, alcohol, water and alcohol mixture) of the distillation system 102 (e.g., within the distillation vessel 106, circulated from the distillation vessel 106 to the heat pump system 100), a stage of the distillation process of the distillation system 102, a temperature and/or pressure of the second fluid flow within the open heat pump system 190, or any combination thereof.

[0061] Further, a flow (e.g., an amount) of the heat storage fluid received via the external source 206 and directed to the heat exchanger 200 of the heat storage system 181 may be controlled (e.g., adjusted), such as via a valve 208. In particular, a position of the valve 208 may be controllably adjusted (e.g., via a controller, control system 250) to adjust the amount of heat storage fluid received by and/or directed to the heat exchanger 200. The amount of heat storage fluid received via the external source 206 (e.g., received by the heat exchanger 200) may controlled by a controller based on one or more operating parameters of the heat pump system 100 and/or the distillation system 102, such as an amount of superheat (e.g., 2 Kelvin [K], 4 K, 3 K, 2-4 K) and/or a temperature of fluid (e g., the heat storage fluid) output by the heat exchanger 200 (e.g., received by the heat storage vessel 202). In particular, an increase in a valve opening of the valve 208 (e.g., increased flow of received heat storage fluid from the external source 206) may cause a decrease in the amount of superheat of the vaporized fluid output by the heat exchanger 200. In such instances, an amount of vaporized fluid (e.g., vaporized fluid mass) may decrease and an amount of liquid fluid flow (e.g., liquid fluid mass) may increase. On the other hand, in response to a decrease in the valve opening of the valve 208 (e.g., decrease in flow of received heat storage fluid from the external source 206), the amount of vaporized fluid flow may increase and the amount of liquid fluid flow may decrease. [0062] Similarly as discussed with respect to FIG. 7, to controllably actuate the valve 204 and/or the valve 208, the HVAC&R system 10 may include the control system 250 (e.g., a controller, an automation controller, an electronic controller, a programmable controller, a valve controller, a cloud-computing device, control circuitry) communicatively coupled to and configured to operate the valve 204, the valve 208, or both to regulate or adjust a respective opening (e.g., position) of the valve 204, the valve 208, or both. In this way, the control system 250 may be configured to adjust an amount (e.g., flow rate, volume) of fluid through the respective valves (e.g., valve openings.) In particular, as discussed herein, the control system 250 is configured to control or adjust an amount of working fluid directed from the portion of the vapor compression circuit 182 to the heat exchanger 200 (e.g., downstream of the compressor 186) by controllably adjusting an opening or position of the valve 204. To this end, the control system 250 may be communicatively coupled to the one or more sensors 252.

[0063] In particular, the sensor 252 may detect a temperature and/or pressure of fluid (e.g., working fluid) within the open heat pump system 190 and the control system 250 may receive the detected temperature and/or pressure of fluid from the sensor 252 as sensor data. Furthermore, the control system 250 may compare the detected temperature and/or pressure of the fluid to one or more thresholds, heating or cooling demands or loads of the distillation system 102, or the like. In addition, the control system 250 may controllably adjust the valve 204 based on the comparison. For example, the control system 250 may determine that the detected temperature and/or pressure of the working fluid of the open heat pump system 190 is greater than a threshold or greater than a heating demand of the distillation system 102. The control system 250 may adjust the valve 204, based on or in response to determining that the temperature and/or pressure of the fluid is greater than the threshold or greater than the heating demand, to increase an amount of working fluid directed towards the heat exchanger 200. In this way, the control system 250 may enable the HVAC&R system 10 to off-load, reduce, an/or store excess heat from the open heat pumps system 190, and transfer (e.g., collect) the excess heat from the working fluid to the heat storage fluid (e.g., via the heat exchanger 200.) Thus, the HVAC&R system 10 may enable the open heat pump system 190 to efficiently and effectively match (e.g., correlate) heating and/or cooling demands or loads of the distillation system 102.

[0064] In a similar way, the control system 250 is configured to control or adjust an amount of heat storage fluid directed from the external source 206 to the heat exchanger 200 by controllably adjusting an opening or position of the valve 208. To this end, the sensor 252 may detect a temperature and/or pressure of fluid (e.g., superheat of the heat storage fluid) output by the heat exchanger 200 (e.g., received by the heat storage vessel 202) and the control system 250 may receive the detected temperature and/or pressure of fluid from the sensor 252 as sensor data. Furthermore, the control system 250 may compare the detected temperature and/or pressure of the fluid to one or more thresholds. In addition, the control system 250 may controllably adjust the valve 208 based on the comparison. For example, the control system 250 may determine that the detected temperature and/or pressure of the heat storage fluid output by the heat exchanger 200 of is greater than a threshold temperature and/or pressure. The control system 250 may adjust the valve 208, based on or in response to determining that the temperature and/or pressure of the fluid is greater than the threshold, to increase an amount of heat storage fluid directed towards the heat exchanger 200 (e.g., from the external source 206). In this way, the control system 250 may enable the HVAC&R system 10 to maintain a consistent or desired ratio of an amount of vaporized heat storage fluid flow (e.g., vaporized fluid mass) and an amount of liquid heat storage fluid flow (e.g., liquid fluid mass) stored in the heat storage vessel 202. Thus, the HVAC&R system 10 may enable the heat storage system 181 to efficiently and effectively maintain a desired ratio of vaporized form versus liquid form of the heat storage fluid flow.

[0065] The one or more sensors 252 may be configured to transmit an indication of a fluid parameter, such as temperature, volume, pressure, and/or flow rate, of the fluid within the HVAC&R system 10 to the control system 250. In some embodiments, the one or more sensors 252 may be configured to transmit the indication when a monitored value of a fluid parameter falls outside of a desired range of values, is above a threshold, is below a threshold, or any combination thereof. For example, when the one or more sensors 250 detects that a fluid parameter value is below a threshold value (e.g., lower limit of the desired range of values) and/or detects that an operational condition value is above a threshold value (e.g., upper limit of the desired range of values), the one or more sensors 250 may be configured to transmit the fluid parameter valve, and indication of the fluid parameter value being outside the desired range, or both to the control system 250. In either case, the control system 250 may be configured to transmit control signals to the valve 204, the valve 208, or both, to adjust an amount of fluid flow through the respective valve based on the received data and/or indication.

[0066] In some embodiments, the one or more sensors 252 may be temperature sensors configured to detect a temperature associated with the HVAC&R system 10, such as a temperature of the working fluid at particular points within the vapor compression circuit 182, the distillation system 102, and/or the heat storage system 181. For example, the one or more sensors 252 may detect a compressor discharge temperature, an evaporator discharge temperature, a heat exchanger discharge temperature, a heat storage vessel temperature, an intermediate vessel discharge temperature, and/or a suction inlet temperature. Additionally or alternatively, the one or more sensors 252 may be pressure sensors configured to detect a pressure of the working fluid at particular points within the vapor compression circuit 182, the distillation system 102, and/or the heat storage system 181. For example, the one or more sensors 252 may detect a compressor discharge pressure, an evaporator discharge pressure, a heat exchanger discharge pressure, a heat storage vessel pressure, an intermediate vessel discharge pressure, and/or a suction inlet pressure.

[0067] Furthermore, the heat storage vessel 202 may be fluidly coupled to one or more components of the distillation system 102 and/or the open heat pump system 190. For example, in some embodiments, the heat storage vessel 202 may be fluidly coupled to the distillation vessel 106 and may be configured to direct a portion of the heated storage fluid (e.g., heated water) to the distillation vessel 106. For example, the HVAC&R system 10 may include one or more additional valves 258 configured to adjust or control an amount of heat storage fluid directed to the one or more components. In particular, the control system 250 may be communicatively coupled to the one or more additional valves 258 and configured to adjust a respective position or opening of the one or more additional valves 258. In this way, the control system 250 is configured to control an amount of the heat storage fluid directed to the one or more components. In some embodiments, the control system 250, may adjust one or more of the additional valves 258 based on data or feedback from a sensor (e.g., one or more sensors 252, temperature sensor, pressure sensor, volume or flow rate sensor), based on an indication of a new batch and/or initiation (e.g., start-up operation) of the distillation process, based on indication of a cleaning, sanitizing, or preparation operations, based on received user input (e.g., from an operator of the distillation system 102), or any combination thereof.

[0068] In this way, as discussed herein, the stored heat (e.g., captured and stored via the heat storage system 181) may be used to provide heat (e.g., as a heated fluid) to the distillation vessel 106 (e g., pre-heat the distillation vessel 106 and/or conduits of the HVAC&R system 10) prior to initiation of a new distillation batch, during initiation process of a new distillation batch, in between distillation batches, for cleaning and/or sanitizing the distillation vessel 106, or any combination thereof. Similarly, in some embodiments, a portion of the heated storage fluid (e.g., heated water) may be directed towards the heat exchanger 184 and/or the compressor 186 to provide additional heat to heat and/or pre-heat the heat exchanger 184 and/or the compressor 186, such as prior to initiation of a new distillation batch, in between distillation batches, for cleaning and/or sanitizing the heat exchanger 184 and/or the compressor 186. For example, the heated storage fluid may be used to provide heat to the distillation process fluid (e.g., water and/or alcohol mixture of the distillation system 102) and/or to the working fluid (e.g., of the heat pump system 190) of the heat exchanger 184. In some embodiments, one or more additional heat exchangers may be used in parallel to the heat exchanger 184 to transfer heat from the heated storage fluid to the process fluid and/or the working fluid of the heat exchanger 184. [0069] The heat exchanger 172 and/or the heat exchanger 200 may be a plate heat exchanger (e.g., comprise a plate arrangement.) In particular, the plate heat exchanger includes a series of plates (e.g., metal plates) arranged such that they form a channel (e.g., void, space) between each two consecutive plates. In addition, the plate heat exchanger includes an arrangement of ports (e.g., with gaskets, openings, in or through the plates) that allows fluids to flow through the channels. For example, a flow of the working fluid received from the heat pump system 100 (e.g., closed heat pump system 160, open heat pump system 190) may flow in a first direction through a first set of the channels (e.g., through every other channel) and along the plates, and an additional flow of the heat storage fluid received may flow in a second direction (e.g., opposite the first direction) through a second set of the channels (e.g., every other channel opposite of the first set of channels) and along the plates. In this way, the plate arrangement of the plate heat exchanger allows for efficient and effective transfer of heat in a counter-flow arrangement. Additionally, in some embodiments, the plates may be corrugated plates (e.g., comprise ridges, fluted, channeled, grooved) that increase turbulence in the fluids as the fluids flow through the plate heat exchanger (e.g., through the channels and along the plates.) The increase in turbulence may increase a heat transfer coefficient of the plate heat exchanger, thus improving efficiency of the transfer of heat from the working fluid to the heat storage fluid. The plate arrangement of the plate heat exchanger may also be more compact and lower in cost to implement as compared to other types or arrangements. In addition, the plate arrangement of plate heat exchanger may enable sufficient separation of the fluids received by the plate heat exchanger, thus decreasing mixing and/or cross-contamination of the fluids. It should be understood that the heat exchanger 172 may be an suitable heat exchanger to transfer heat from the working fluid of the heat pump system 100 to the heat storage fluid, such as a tube and shell heat exchangers, plate fin heat exchangers, regenerative heat exchangers, double pipe heat exchangers, etc.

[0070] In the manners described above, present embodiments include a heat storage system that enables a heat pump system to more efficiently and/or effectively satisfy (e.g., match) varying heating and/or cooling demands during various stages of distillation operations of a distillation system. In particular, the heat storage system is configured to capture and store excess heat, such as when a target heating load or a heating demand of the distillation system is lower than a heating output of the heat pump system. The heat storage system also enables utilization of the stored heat (e.g., excess heat) captured (e.g., received) via the heat storage system for various purposes with the distillation system, such as during distillation stages when a target heating load or a heating demand of the distillation system is higher than a heating output of the heat pump system. In addition, the heat storage system may enable the stored heat to be used in other manners associated with the distillation process, such as sanitizing (e.g., cleaning) components of the distillation system (e.g., the distillation vessel) between distillation batches and/or for preheating the components of the distillation system (e.g., during initiation of a new distillation batch). In this way, the heat storage system may provide an increase in efficiency (e.g., energy efficiency) and cost effectiveness of the distillation processes and thus, the distillation system.
