Description

Heat pump system {HEAT PUMP SYSTEM}

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

A heat pump system is a device that transfers thermal energy from a low temperature to a high temperature. For example, a heat pump is a device that generates high-temperature heat by absorbing low-temperature heat sources from unused energy such as air, river water, and waste heat, and from renewable energy such as geothermal and solar heat. It acts as 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 cooled by air and the suction gas state of the compressor is dry saturated steam, when the condensation temperature changes, the change in the Moliere diagram shows the change in the refrigeration cycle. drive in the state of However, in summer, when the outside air temperature is high, the condensing capacity of the condenser is reduced, and a higher condensing temperature and pressure are required, the pressure rises. As such, the increase in the condensing pressure increases the compression ratio to increase the discharge gas temperature, reduces the refrigeration effect, and at the same time increases the compression work, and consequently reduces the performance coefficient.

In addition, the change in the Moliere curve for the case where the evaporation temperature is changed while the condensation temperature is constant in the air-cooled refrigeration cycle is as follows. The state of suction gas to the compressor is dry saturated steam. While operating in the state of the refrigeration cycle, the evaporation temperature decreases and the evaporation pressure also decreases according to a change in the cooling state of the evaporator (eg, decrease in the outdoor air temperature in winter). As such, the reduction in evaporation pressure increases the compression ratio and raises the discharge gas temperature, thereby lowering the volumetric efficiency of the compressor. also lowers

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 and humidification is required. When the heat pump system performs cooling operation, the indoor temperature decreases and the humidity decreases. On the air conditioning diagram, it can be seen that the relative humidity decreases as the temperature decreases, and the cooling and dehumidifying effect is shown. However, the power consumption of the compressor is relatively large, so the power consumption increases. 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 air conditioning in a building, 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.

On the other hand, in a liquid desiccant-linked heat pump system, air conditioning is achieved through three fluids, liquid desiccant, refrigerant, air, and heat exchange, and if one of the three fluids changes, the entire cycle changes. Since it is sensitively affected by the external temperature and humidity conditions, it is necessary to control each cycle according to the change in temperature conditions for smooth air conditioning. In addition, since the outdoor air conditioning load is constantly changing, it is difficult to optimize the energy balance of the entire heating and cooling cycle if there is no operation control logic according to the outdoor air load condition.

On the other hand, when the temperature of the solar cell module increases by 1°C, 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 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 irregular facility operation for cooling water injection is required according to the unpredictable change of the external environment, which causes difficulties in management and operation. In addition, even if the coolant sprayed on the module is pure, water scale occurs, and deposits such as evaporation residues lower the light incident efficiency.

One object of the present invention is to recover heat, which is the unused energy of a solar cell, and use it for the operation of the heat pump system, and to improve the operation efficiency of the heat pump system by using a liquid desiccant, while also responding to changes in solar radiation and seasonal outdoor temperature.

And, in the second mode of the heat pump system 100, the flow of the liquid desiccant (D) is a dilute solution at the bottom of the evaporation unit 140, the liquid desiccant heat exchanger 161, the pump 162, the condensing unit 120 ) of the first nozzle 123, the condenser 120a, the concentrated solution at the bottom of the condensing unit 120, the liquid desiccant heat exchanger 161, the pump 162, the second nozzle 143 of the evaporator 140, The evaporator 140a and the dilute solution at the bottom of the evaporator 140 may be formed in this order. Here, the flow of indoor air is supplied (heating/humidifying) into the room after passing through the shell side of the condenser 120a after the exhaust air recovered from the air mixing chamber 150 and the outdoor air are mixed. In the flow of outdoor air, the exhaust air recovered from the air mixing chamber 150, indoor air, and outdoor air are mixed, passed through the shell side of the evaporator 140a, and then discharged to the outdoors.

Hereinafter, an 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, on the side of the evaporator 140, which is an indoor unit, the air (indoor air and outdoor air) mixed in the air mixing chamber 150 is transferred to the evaporator 140a. As it passes through the shell side of the air, the temperature of the air decreases, resulting in a cooling effect.

And the liquid dehumidifying agent D sprayed through the first nozzle 143 adsorbs moisture contained in the indoor air to generate a dehumidifying effect, and the cooling and dehumidified air is supplied to the room.

In addition, the liquid desiccant (D), which has absorbed moisture while passing through the shell of the evaporator 140a, is reduced in temperature and becomes a weak fluid, and is collected in the lower portion of the evaporator 140 . The dilute solution of the evaporation unit 140 is supplied from the condensing unit 120 at a relatively high temperature through the liquid desiccant heat exchanger 161 before being transferred through the pump 162. The liquid desiccant of strong fluid ( D) and the pump 162 are directly mixed at the suction side to exchange heat. As the capacity of the heat pump system 100 increases, it has a great influence on efficiency improvement. At this time, the temperature of the liquid desiccant (D) of the dilute solution increases, which is supplied to the shell side of the condenser 120a through the first nozzle 123 of the condensing unit 120 .

On the other hand, the liquid desiccant (D) of the strong fluid of the condensing unit 120 is transferred through the pump 161 and the liquid desiccant liquid desiccant (D) at a relatively low temperature through the liquid desiccant heat exchanger 161 The temperature of the liquid desiccant (D) of the concentrated solution is lowered while exchanging heat with the liquid, and this is supplied to the shell side 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 dehumidifier (D) removes moisture from the air while generating an effect of continuously supplying a low outdoor temperature to heat. It is possible to reduce the power consumption of the compressor 110 , which can be said to be the heart of the pump system 100 , and this results in 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 the outdoor unit, the liquid desiccant D of the ash supplied from the evaporator 140 is supplied to the first nozzle 123 of the condensing unit 120 through the pump 162 and is sprayed The sprayed liquid desiccant (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 absorbs moisture through the auxiliary heat source unit 124 and the condenser 120a. The liquid desiccant (D) is regenerated to release moisture.

And the liquid desiccant (D), which removes moisture while passing through the condenser (120a) shell side, increases in temperature and becomes a concentrated solution and is collected under the condensing unit (120). In addition, the air in which the outdoor air and the above-mentioned heat are mixed in summer passes to the shell side of the condenser 120a and is discharged to the outside while performing air-cooling heat exchange.

The higher the outdoor air temperature in summer, the higher the temperature of the condenser 120a rises, so that the compressor 110 uses a lot of power. (110) increases the efficiency while consuming relatively little power.

Hereinafter, an operating principle of the heat pump system 100 in the second 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, the air (the arrangement and the outdoor air) mixed in the air mixing chamber 150 in winter is converted into the condenser ( As it passes through the shell side of 120a), the temperature of the air increases, resulting in a heating effect.

In addition, the liquid desiccant (D) sprayed through the first nozzle 123 generates a humidifying effect by additionally supplying more water than the moisture in the adsorbed indoor air and the rate at which the liquid desiccant (D) is regenerated by the condenser 120a. The heated and humidified air is supplied to the room.

In addition, the liquid desiccant (D), which regenerated moisture while passing through the shell of the condenser 120a, increases in temperature and becomes a concentrated solution, and is collected in the lower portion of the condensing unit 120 . The concentrated solution of the condensing unit 120 is transferred through the pump 162 and heat exchanged with the liquid desiccant (D) of the ash solution supplied from the evaporation unit 140 at a relatively low temperature through the liquid desiccant heat exchanger 161. While the temperature of the liquid desiccant D 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 .

On the other hand, the liquid desiccant (D) of the ash solution of the evaporator 140 is transferred through the pump 162 and exchanges heat with the concentrated solution liquid desiccant (D) at a relatively high temperature through the liquid desiccant heat exchanger 161 The temperature of the liquid desiccant D of the ash solution increases, which is supplied to the shell side of the condenser 120a through the first nozzle 123 of the condensing unit 120 .

Therefore, in winter, the outdoor air supplied to the condensing unit 120 is heated and humidified and supplied back to the room, and the liquid dehumidifier (D) achieves a humidifying effect together with the additionally supplied water supply, and a high outdoor temperature is continuously supplied. It is possible to reduce the power consumption of the compressor 110 by generating an effect that increases the efficiency of the heat pump system 100 .

In addition, on the side of the evaporator 140 which is an indoor unit, the liquid desiccant D of the concentrated solution supplied from the condensing unit 120 is supplied to the second nozzle 143 of the evaporator 140 through the pump 162 . and sprayed The sprayed liquid desiccant (D) is absorbed to remove moisture. And the liquid desiccant (D) adsorbing moisture while passing through the shell side of the evaporator (140a) is reduced in temperature and becomes a ash solution and is collected in the lower portion of the evaporator (140). In addition, the outdoor air in winter passes through the shell side of the evaporator 140a and is discharged to the outside while performing air-cooling heat exchange.

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

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

FIG. 9 is a diagram illustrating a second mode of the heat pump system 100 shown in FIGS. 1 and 2 , when the amount of insolation exceeds the first level of insolation, when the amount of insolation is less than the second level of insolation, the amount of insolation is less than or equal to the first level of insolation. It is a flowchart showing the operation logic of the heat pump system 100 under the condition in which the second insolation level is higher than the second insolation level.

Referring to FIG. 9 , in the second mode of the heat pump system 100 , when the amount of insolation exceeds the first level of insolation, when the amount of insolation is less than the second level of insolation, the amount of insolation When the first solar radiation level is less than or equal to the second solar radiation level or higher, the control of the heat pump system 100 may be differently performed according to the conditions for the outdoor temperature.

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

According to the control method of the control unit according to the outdoor environment variables described above, in the summer season of the first mode, when heat recovery heat for liquid desiccant regeneration is excessively introduced under high temperature conditions, the load on the heat pump refrigerant cycle is increased. do. If more heat recovery heat flows in than the amount of heat that the refrigerant cycle can handle, the refrigerant cycle temperature rises, making cooling impossible. Therefore, it is possible to reduce power consumption by reducing the load on the heat pump cycle by controlling the amount of heat recovery inflow with a damper according to the temperature condition and to enable stabilization of the refrigerant cycle.

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 regeneration heat, and it is possible to prevent excessive power consumption by reducing the operation of the heat pump compressor 110 according to temperature conditions.

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

For example, when the outdoor temperature in summer operating in the first mode is 30° C. and the amount of insolation is 900 W/m ² , in the case of the heat recovery fan 11a, the module temperature of the solar cell 10 decreases in efficiency. Accordingly, the heat recovery fan 11a can be operated 100%. In this case, the flow rate through the heat recovery fan 11a may be 35 CMM (m ³ /min). In addition, the inflow flow rate of the regeneration unit, that is, the first outlet 151c, is the heat pump system ( 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 a heat flow rate of about 17.5 CMM 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 indoor 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 in the 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 operates at about 45 Hz, and the outdoor fan 121 may be operated 100% to reduce the load on the compressor 110 .

On the other hand, when the outdoor air temperature in winter operating in the second mode is 7° C. or less and the amount of insolation is 400 to 900 W/m ² , in the case of the flow rate of the heat recovery fan 11a, high heat (about 20 to about 20 25 ℃), the heat recovery fan 11a may be operated by 40%. In this case, the flow rate through the heat recovery fan 11a may be 14 CMM (m ³ /min). And, the inflow flow rate of the humidifier, that is, the second outlet 152c, 100% open the heat inlet 151a to recover the heat of 20 to 25° C. It can be supplied indoors.

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