Description

Heat pump system {HEAT PUMP SYSTEM}

The present invention relates to a heat pump system configured to transmit a low temperature heat source to a high temperature or a high temperature heat source to a low temperature.

The heat pump system refers to a device that transfers heat energy from a low temperature to a high temperature. For example, it is a device that generates high-temperature heat by absorbing unused energy such as air, river water, and waste heat, and low-temperature heat sources of new and renewable energy such as geothermal and solar heat. It plays the role of a heat conversion device that supplies heat in the form of heat.

In the conventional heat pump system, when the evaporation temperature is constant in an air-cooled refrigeration cycle, and the state of the suction gas of the compressor is dry saturated steam, when the condensation temperature changes, the change on the Molière diagram shows the refrigeration cycle. Drive in the state of. However, in the summer, when the outside air temperature is high, the condensing capacity of the condenser decreases, and when a higher condensing temperature and pressure is required, the pressure rises. In this way, the increase of the condensing pressure increases the compression ratio to increase the discharge gas temperature, decreases the refrigeration effect, and increases the compression work, resulting in a decrease in the coefficient of performance.

In addition, when the condensation temperature is kept constant in the air-cooled refrigeration cycle and the evaporation temperature is changed, the change in the Moliere diagram is as follows. The state of the suction gas to the compressor is dry saturated steam. It operates in the state of the refrigeration cycle, and the evaporation temperature decreases and the evaporation pressure decreases according to the change in the cooling condition of the evaporator (for example, decrease in the outside temperature in winter). In this way, the reduction of the evaporation pressure increases the compression ratio and increases the discharge gas temperature to reduce the volumetric efficiency of the compressor.In particular, the reduction of the suction pressure to the compressor increases the specific volume of the refrigerant vapor, resulting in a decrease in the amount of refrigerant circulation and the refrigeration effect. Also degrades.

On the other hand, in summer, the relative humidity of the outside air is high, so dehumidification is required, and in winter, the outside air is dry, so humidification is required. When the cooling operation is performed in the heat pump system, the indoor temperature decreases and the humidity decreases. In the air conditioning diagram, it can be seen that the relative humidity decreases as the temperature decreases, and the cooling dehumidification effect is shown. However, a relatively large amount of power consumption of the compressor is required, which increases the power consumption. Therefore, there is a tendency to use a dehumidifier with relatively low power consumption only for dehumidification. In addition, in the case of a system applied to building air conditioning, the functions of dehumidification and humidification are implemented in the air conditioner, but there is a disadvantage in that the installation area and cost of the air conditioner are large.

Meanwhile, in the liquid dehumidifying agent-linked heat pump system, air conditioning is achieved through heat exchange and heat exchange with the three fluids, liquid dehumidifying agent, refrigerant, and air. Since it is sensitive to outside temperature and humidity conditions, it is necessary to control each cycle according to changes in temperature conditions for smooth air conditioning. In addition, since the outside air cooling and heating load is constantly changing, it is difficult to optimize the entire heating and cooling cycle energy balance without the operation control logic according to the outside air load condition.

On the other hand, when the temperature of the solar cell module increases by 1℃, the output decreases by about 0.5%. The output characteristics of the solar cell module change as the atmospheric temperature rises and falls when solar energy is incident, and this is also related to the thermal characteristics of silicon properties. Also, the MPP (Maximum Power Point) of the module changes according to the temperature.

In addition, in the case of water cooling, cooling water is sprayed in order to reduce the temperature of the surface of the solar cell module. Accordingly, it is necessary to consume a lot of cooling water in the place where the solar cell array is installed, and it is difficult to manage and operate because irregular facility operation for spraying cooling water is required due to changes in external environment that are difficult to predict. In addition, even if the cooling water sprayed on the module is pure, water scale occurs, and sediments such as evaporation residues lower the light incident efficiency.

An object of the present invention is to recover heat that is unused energy of a solar cell and utilize it for operation of a heat pump system, and to improve the operation efficiency of a heat pump system by using a liquid dehumidifying agent, while reducing the amount of insolation and seasonal outdoor temperature changes.

In the second mode of the heat pump system 100, the flow of the liquid dehumidifying agent D is a dilute solution at the bottom of the evaporating unit 120, the liquid dehumidifying agent heat exchanger 161, the pump 162, and the condensing unit 120. ) Of the first nozzle 123, the condenser 120a, the agricultural solution at the bottom of the condensing unit 120, the liquid dehumidifying agent heat exchanger 161, the pump 162, the second nozzle 143 of the evaporation unit 140, It may be formed in the order of the evaporator 140a and the dilute solution at the bottom of the evaporator 140. Here, the indoor air flow is supplied to the room (heating/humidifying) after passing through the shell side of the condenser 120a after mixing the exhaust air and outdoor air recovered from the air mixing chamber 150. In addition, the outdoor air flow is mixed with the exhaust air recovered from the air mixing chamber 150, the indoor air, and the outdoor air, passes through the shell side of the evaporator 140a, and then is discharged to the outside.

Hereinafter, the operating principle of the heat pump system 100 in the first mode will be described.

Looking at the cooling operation principle in the first mode of the heat pump system 100, from the side of the evaporator 120, which is an indoor unit, the air (indoor air and outdoor air) mixed in the air mixing chamber 150 is the evaporator 120a. As it passes through the shell side, the air temperature decreases, resulting in a cooling effect.

In addition, the liquid dehumidifying agent D sprayed through the first nozzle 123 absorbs moisture contained in the indoor air to generate a dehumidifying effect, and the air cooled and dehumidified in this way is supplied to the room.

In addition, the liquid dehumidifying agent (D), which has adsorbed moisture while passing through the shell of the evaporator 120a, decreases in temperature, becomes a Weak Fluid, and is collected under the evaporator 120. Before the dilute solution of the evaporation unit 120 is transferred through the pump 162, the liquid dehumidifying agent of a strong fluid supplied from the condensing unit 140 at a relatively high temperature through the liquid dehumidifying agent heat exchanger 161 ( D) and the suction side of the pump 162 is made to perform heat exchange while being mixed directly. The larger the capacity of the heat pump system 100, the greater the effect on efficiency improvement. At this time, the temperature of the liquid dehumidifying agent (D) of the dilute solution is increased, which is supplied to the shell side of the condenser (120a) through the first nozzle (123) of the condenser (120).

On the other hand, the liquid dehumidifying agent (D) of the strong fluid in the condensing unit 120 is transferred through the pump 161 and is a relatively low temperature dilute solution liquid dehumidifying agent (D) through the liquid dehumidifying agent heat exchanger 161 The temperature of the liquid dehumidifying agent (D) of the agricultural solution decreases while exchanging heat with and is supplied to the shell of the evaporator 140a through the second nozzle 143 of the evaporator 140.

Therefore, in summer, the indoor air supplied to the evaporator 140 is cooled and dehumidified to be supplied back to the room, and the liquid dehumidifying agent (D) removes moisture from the air and generates an effect of continuously supplying low outside air temperature. It is possible to reduce the power consumption of the compressor 110, which is the heart of the pump system 100, which leads to an increase in the efficiency of the heat pump system 100.

On the other hand, on the side of the condensing unit 120 that is an outdoor unit, the liquid dehumidifying agent D of the ash solution supplied from the evaporating unit 140 is supplied to the first nozzle 123 of the condensing unit 120 through the pump 162 Is sprayed. The sprayed liquid dehumidifier (D) passes through the heat supply unit 125 to which the heat generated through the solar cell 10 and the heat recovery device 11 is supplied, and collects moisture through the auxiliary heat source unit 124 and the condenser 120a. Existing liquid dehumidifier (D) is regenerated to release moisture.

In addition, the liquid dehumidifying agent (D) from which moisture has been removed while passing through the condenser (120a) shell side increases in temperature and becomes an agricultural solution, and is collected under the condensation unit (120). In addition, the air in which the outdoor air and the air in which the heat is mixed in the summer season passes through the shell side of the condenser 120a and is discharged to the outside while performing air-cooled heat exchange.

The higher the outdoor temperature in summer, the higher the temperature of the condenser 120a, and the compressor 110 uses a lot of power.The low-temperature liquid dehumidifier (D) supplied to the condenser 120 serves to lower the outdoor temperature. (110) increases efficiency while consuming relatively little power.

Hereinafter, the operating principle of the heat pump system 100 in the first mode will be described.

Looking at the heating operation principle in the second mode of the heat pump system 100, from the side of the condensing unit 120, which is an outdoor unit, air mixed in the air mixing chamber 150 in winter (the above arrangement and indoor air and outdoor air). As the air passes through the shell side of the condenser 120a, the temperature of the air increases, thereby generating a heating effect.

In addition, the liquid dehumidifying agent (D) sprayed through the first nozzle (123) generates a humidification effect by additionally supplying more water than the ratio of regenerating the liquid dehumidifying agent (D) in the adsorbed indoor air and the condenser (120a). The heated and humidified air is supplied to the room.

In addition, the liquid dehumidifying agent (D), which has regenerated moisture while passing through the condenser (120a) shell side, increases in temperature, becomes an agricultural solution, and is collected in the lower portion of the condenser (120). The agricultural solution in the condensing unit 120 is transferred through the pump 162 and exchanged with the liquid dehumidifying agent (D) of the ash solution supplied from the evaporation unit 140 at a relatively low temperature through the liquid dehumidifying agent heat exchanger 161. While the liquid dehumidifying agent (D) temperature of the ash solution is lowered, it is supplied to the shell side of the evaporator 140a through the second nozzle 143 of the evaporator 140.

Meanwhile, the liquid dehumidifying agent (D) of the ash solution of the evaporation unit 140 is transferred through the pump 162 and heat-exchanging with the agricultural solution liquid dehumidifying agent (D) of a relatively high temperature through the liquid dehumidifying agent heat exchanger 161 The liquid dehumidifying agent (D) temperature of the ash solution is increased, which is supplied to the shell side of the condenser (120a) through the first nozzle (123) of the condenser (120).

Therefore, in winter, the indoor air supplied to the condensing unit 120 is heated and humidified to be supplied back to the room, and the liquid dehumidifying agent (D) achieves a humidification effect with additional water supply, and a high outside temperature is continuously supplied. By generating an effect that can reduce the power consumption of the compressor 110, this brings about an increase in the efficiency of the heat pump system (100).

And, from the side of the evaporation unit 140, which is an indoor unit, the liquid dehumidifying agent (D) of the agricultural solution supplied from the condensing unit 120 is supplied to the second nozzle 143 of the evaporation unit 140 through the pump 162 And sprayed. The sprayed liquid dehumidifier (D) is absorbed to remove moisture. In addition, the liquid dehumidifying agent (D), which has absorbed moisture while passing toward the shell of the evaporator 140a, decreases in temperature and becomes an ash solution, and is collected under the evaporator 140. In addition, outdoor air in winter passes through the shell side of the evaporator 120a and is discharged to the outside while performing air-cooled heat exchange.

Meanwhile, the first outside temperature may be set to 30°C, and the second outside temperature may be set to 7°C.

Hereinafter, the operation logic of the heat pump system 100 during winter season will be described with reference to FIG. 9.

9 is, in the second mode of the heat pump system 100 shown in FIGS. 1 and 2, when the solar radiation exceeds the first solar radiation level, when the solar radiation is less than the second solar radiation level, the solar radiation is less than or equal to the first solar radiation level. In addition, it is a flow chart showing the operation logic of the heat pump system 100 under the condition of the second solar radiation level or higher.

Referring to FIG. 9, in the second mode of the heat pump system 100, when the insolation exceeds the first insolation level, the controller is less than the second insolation level, the insolation amount When the first insolation level is lower than the second insolation level or higher, the heat pump system 100 may be controlled differently according to a condition for the outside temperature.

First, when the outside temperature is less than the second outside temperature, the degree of operation of the compressor 110 is controlled to 100%, the degree of operation of the outdoor fan 121 is controlled to 100%, and The degree of inflow of the array is controlled to 100%, the degree of inflow of the outdoor air into the air mixing chamber 150 is controlled to be 0%, and the agent supplied from the air mixing chamber 150 to the evaporation unit 140 2 It can be made to control the supply of mixed air to 100%.

Meanwhile, the first outside temperature may be set to 30°C, and the second outside temperature may be set to 7°C.

According to the control method of the control unit according to the outdoor environment variable described above, in the summer of the first mode, when excessive heat recovery heat for regeneration of the liquid dehumidifier is introduced under high temperature conditions, the heat pump refrigerant cycle load increases. do. When the amount of heat recovery heat flows in more than the amount of heat the refrigerant cycle can handle, the temperature of the refrigerant cycle rises and cooling becomes impossible. Therefore, by controlling the heat recovery inflow amount with a damper according to the temperature condition, the load of the heat pump cycle can be reduced, power consumption can be reduced, and the refrigerant cycle can be stabilized.

In addition, in the case of a relatively low temperature summer season, it is possible to increase the amount of heat recovery inflow and use it for regenerative heat, and by reducing the operation of the heat pump compressor 110 according to temperature conditions, excessive power consumption can be prevented in advance.

On the other hand, in the winter season, the load of the compressor 110 increases due to low temperature conditions. In order to solve this problem, heat can be obtained at a higher temperature than outside air by supplying the recovered heat to the outdoor heat exchanger. Accordingly, the load of the compressor 110 can be reduced and power consumption can be reduced.

For example, when the summer outside temperature operating in the first mode is 30°C and the solar radiation is 900W/m ² , in the case of the heat recovery fan 11a, the module temperature of the solar cell 10 decreases. Accordingly, 100% of the heat recovery fan 11a can be operated. At this time, the flow rate through the heat recovery fan 11a ^{may be 35CMM (m 3} /min). In addition, the inflow flow rate of the regeneration unit, that is, the first outlet 151c, is the heat pump system (approximately 50 to 65°C) when excessive heat (approx. The temperature of 100) is too high. Therefore, it is possible to optimize the energy balance of the heat pump system 100 by opening the heat inlet 151a for regeneration by 50% and discharging the heat flow rate of about 17.5CMM to the outside air. In addition, in the case of the inflow flow rate of the dehumidifying unit, that is, the second outlet 152c, the internal air inlet 152a and the second outdoor air inlet 152b are provided so that 70% of ventilation and 30% of outdoor air can be introduced to improve indoor air quality. Adjust at a ratio of 7:3 (ventilation flow rate: 84CMM/ outside air flow rate: 36CMM)

In addition, in the operation of the heat pump system 100, the compressor 110 is operated at about 45 Hz, and the outdoor fan 121 may be operated 100% in order to reduce the load of the compressor 110.

On the other hand, when the outside temperature of the winter season operating in the second mode is 7°C or less, and the solar radiation is 400 to 900 W/m ² , in the case of the flow rate of the heat recovery fan 11a, high heat dissipation (about 20 to 25°C), the heat recovery fan 11a may be operated by 40%. At this time, the flow rate through the heat recovery fan 11a ^{may be 14CMM (m 3} /min). In addition, the inflow flow rate of the humidifying unit, that is, the second outlet 152c, opens 100% of the heat inlet port 151a to recover the heat at 20 to 25°C, so that all of the heat flow rate of about 14CMM flows into the humidification unit. Can be supplied indoors.

In addition, in the operation of the heat pump system 100, the compressor 110 is operated at about 45 Hz, and the outdoor fan 121 may be operated 100% in order to reduce the load of the compressor 110.
