The utility model provides a heat energy comprehensive utilization system based on a composite air conditioner, which is suitable for an application scene of recycling condensation heat in the composite air conditioner system, and can recycle the condensation side heat energy of the composite air conditioner system for industrial heat supply or living heat supply, thereby realizing the recycling of the heat energy and further solving the problem of serious heat energy waste of the condensation side of the traditional composite air conditioner system.
Referring to fig. 1, in the present embodiment, a heat energy comprehensive utilization system based on a compound air conditioner includes a coupled water-cooled condenser 1, a compound refrigeration cycle system 2, and a heat-taking side water supply system 3.
Specifically, the coupling water-cooled condenser 1 includes an air-conditioning condensing side hot-flow passage 101 and an air-conditioning condensing side cold-flow passage 102;
the composite refrigeration cycle system 2 comprises an air-conditioning compressor 201, an air-cooled condensing assembly 202, a fluorine pump 203, an air-conditioning throttling device 204 and an air-cooled evaporating assembly 205 which are sequentially communicated to form a cycle; wherein, the air-conditioning condensing side heat flow channel 101 and the air-cooling condensing assembly 202 are connected in parallel between the air-conditioning compressor 201 and the fluorine pump 203;
the heat-taking side water supply system 3 comprises a heat-taking water tank 301 and a heat-taking water pump 302; wherein, the hot water taking tank 301, the hot water taking pump 302 and the cold flow channel 102 on the condensing side of the air conditioner are sequentially communicated to form a circulation.
Further, an air-cooled electric control valve 206 is arranged between the air-conditioning compressor 201 and the air-cooled condensing assembly 202; a water-cooling electric control valve 207 is arranged between the air-conditioning compressor 201 and the air-conditioning condensation side heat flow channel 101. The air-cooled electric control valve 206 is selectively opened singly, the water-cooled electric control valve 207 is opened singly, or the air-cooled electric control valve 206 and the water-cooled electric control valve 207 are opened simultaneously, so that the refrigerant sent by the air-conditioner compressor 201 can flow into the air-cooled condenser assembly 202 singly, flow into the coupled water-cooled condenser 1 singly, or flow into the air-cooled condenser assembly 202 and the coupled water-cooled condenser 1 simultaneously.
The heat energy comprehensive utilization system based on the composite air conditioner provided by the embodiment has the following working process:
s10: in general, the air-cooled electric control valve 206 is opened, the water-cooled electric control valve 207 is closed, the air-conditioning compressor 201 heats the refrigerant and then sends the refrigerant into the air-cooled condensing assembly 202, the air-cooled condensing assembly 202 blows out hot air (which is equivalent to the heat energy in the refrigerant being dissipated into the atmosphere in a hot air manner), the refrigerant is throttled and depressurized by the air-conditioning throttling device 204, evaporated and vaporized by the air-cooled evaporating assembly 205, and then flows back into the air-conditioning compressor 201 to complete the cycle;
optionally, the inlet side of the fluorine pump 203 is provided with a refrigerant storage tank 208, so as to avoid cavitation problem of the fluorine pump 203 caused by insufficient refrigerant at the suction side;
s20: when the heat energy of the condensation side needs to be recovered, the water-cooling electric control valve 207 can be opened (the air-cooling electric control valve 206 can be kept fully opened, the opening degree is reduced or directly closed as required), so that part or even all of the refrigerant enters the air-conditioning condensation side heat flow channel 101 of the coupled water-cooling condenser 1 through the water-cooling electric control valve 207;
meanwhile, the hot water taking pump 302 works, water with lower temperature in the hot water taking tank 301 is supplied into the cold flow channel 102 on the condensation side of the air conditioner of the coupling water-cooled condenser 1, the temperature of the water rises after the water absorbs heat energy in the coupling water-cooled condenser 1, and then the water returns to the hot water taking tank 301, and the water in the whole hot water taking tank 301 can be gradually heated and raised without stopping circulation, so that the recovery and storage of the heat energy on the condensation side are completed.
Therefore, the heat energy comprehensive utilization system based on the composite air conditioner provided by the embodiment can recover heat energy at the condensation side of the composite air conditioner system and store the recovered heat energy in a hot water mode, so that the problem of serious heat energy waste at the condensation side of the conventional composite air conditioner system is solved.
Further, when the air-cooled evaporating assembly 205 is used for cooling a place such as a data center, the problem of heat energy waste is particularly serious because the data center needs to perform continuous cooling throughout the year, especially in a medium-low temperature environment, the demand of cooling load is small, but the cooling load is also performed at low frequency and continuous, so after the heat-taking side water supply system 3 is additionally arranged, annual heat recovery can be realized, and meanwhile heat pump heat supply in partial medium-low temperature environment is supplemented, so that energy saving is realized.
Optionally, when the condensation temperature of the composite refrigeration cycle system 2 is higher, the grade of the heat energy that the refrigerant can provide in the coupled water-cooled condenser 1 is higher (the temperature is higher), at this time, if the heat energy is directly stored in the heat-taking water tank 301 in a hot water manner, the volume of the heat-taking water tank 301 is greatly increased, and the high-grade heat energy is wasted, so referring to fig. 2, a plurality of heat recovery heat exchangers 303 can be connected in series and/or in parallel between the heat-taking water pump 302 and the heat-taking water tank 301, so that the heat water with higher grade after leaving the coupled water-cooled condenser 1 enters each heat recovery heat exchanger 303 first, and after meeting the industrial heat supply purpose, the heat energy is reduced to the heat water with lower grade, and then stored in the heat-taking water tank 301, thereby realizing the graded utilization of the high-grade heat energy.
Optionally, the heat recovery heat exchanger 303 is a shell-and-tube heat exchanger or a plate heat exchanger, and further, a hot-flow side pipeline of the heat recovery heat exchanger 303 is connected between the hot-water taking pump 302 and the hot-water taking tank 301, and a cold-flow side pipeline can be connected into industrial equipment needing heat, such as a steam turbine set, a preheating heat exchanger, and the like.
It should be noted that, the working state of the composite refrigeration cycle system 2 will change throughout the year, so the condition of receiving heat in the cold flow channel 102 of the condensation side of the air conditioner is unstable, and the availability of unstable heat energy is poor, so the heat-taking water tank 301 needs to be set to store the heat received in the cold flow channel 102 of the condensation side of the air conditioner, so as to supply heat stably and outwards subsequently, and reduce the difficulty of heat utilization.
Optionally, a water source heat pump unit 304 and a heat pump water pump 305 may be added to utilize the low-grade heat energy of the hot water in the hot water tank 301 again, and convert the heat energy into the heat energy in the domestic water required by the residential user.
Specifically, the water source heat pump unit 304 includes a heat pump compressor, a heat pump water-cooled condenser, a heat pump throttling device, and a water-cooled evaporator;
the heat pump water-cooling condenser comprises a heat pump condensation side heat flow channel and a heat pump condensation side cold flow channel 3041, and the water-cooling evaporator comprises a heat pump evaporation side heat flow channel 3042 and a heat pump evaporation side cold flow channel;
the heat pump compressor, the heat pump condensation side heat flow channel, the heat pump throttling device and the heat pump evaporation side cold flow channel are sequentially communicated to form a cycle (the cycle is a common heat pump refrigerant cycle, and description is omitted in this embodiment), and it should be noted that in the cycle, the heat pump evaporation side cold flow channel is required to absorb heat energy to complete evaporation and vaporization (the evaporation temperature is generally lower, therefore, even if the temperature of hot water in the hot water tank 301 is lower, the requirement of the evaporation temperature can still be met), and then the heat pump condensation side heat flow channel can release heat to the heat pump condensation side cold flow channel 3041;
the heat-taking water tank 301, the heat pump water pump 305 and the heat pump evaporation side heat flow channel 3042 are sequentially communicated and form a cycle, and the cycle has the meaning that the hot water in the heat-taking water tank 301 can be fed into the heat pump evaporation side heat flow channel 3042 so as to provide heat energy for the heat pump evaporation side cold flow channel, so that the heat pump condensation side heat flow channel releases heat to the heat pump condensation side cold flow channel 3041.
After the heat energy conversion of the water source heat pump unit 304, the heat energy in the hot water tank 301 is already transferred to the cold flow channel 3041 on the condensation side of the heat pump, so the user water tank 306 and the user upstream water pump 307 are required to be set to recover the heat energy in the cold flow channel 3041 on the condensation side of the heat pump. In this embodiment, the user water tank 306, the user upstream water pump 307, and the heat pump condensation side cold flow channel 3041 are sequentially connected and form a cycle, and the cycle can convert the heat energy in the heat pump condensation side cold flow channel 3041 into the heat energy of the water in the user water tank 306.
After the water in the user water tank 306 is heated, a subsequent domestic water usage scheme can be implemented, specifically, a user downstream water pump 308 and a user water device 309 are set, and the user water tank 306, the user downstream water pump 308 and the user water device 309 are sequentially communicated and form a circulation.
Optionally, the user water device 309 includes at least one of a floor heating water pipe, a heating fan coil, a radiator, a heating fin, and the like, which are disposed in parallel. The user downstream water pump 308 supplies the hot water in the user water tank 306 directly to a floor heating water pipe, a heating fan coil, a heating fin, or the like, i.e., provides heat energy directly to residential users.
In this embodiment, a differential pressure bypass pipeline 310, which is parallel to the user water tank 306, is further connected between the user downstream water pump 308 and the user water tank 306, and when the differential pressure between the outlet side of the user downstream water pump 308 and the inlet side of the user water tank 306 is too large, it is indicated that the water intake of the user water tank 309 is insufficient, and in order to avoid damaging the user downstream water pump 308 and related pipelines, the differential pressure bypass pipeline 310 should be opened, so as to skip the user water tank 309, and directly convey water from the outlet side of the user downstream water pump 308 to the inlet side of the user water tank 306.
Optionally, the differential pressure bypass line 310 is provided with a mechanical differential pressure valve, and when the differential pressure reaches the designed working differential pressure of the mechanical differential pressure valve, the differential pressure bypass line is automatically opened; alternatively, in some other embodiments, the differential pressure bypass line 310 is provided with two water pressure sensors, a bypass electric control valve between the two water pressure sensors, and a control device electrically connected to the two water pressure sensors and the bypass electric control valve, and when the control device detects that the differential pressure between the two water pressure sensors reaches a preset value, the control device controls to open the bypass electric control valve.
Optionally, two, three or even more heat flow channels 101 on the condensation side of the air conditioner may be further disposed in the coupling water-cooled condenser 1, which is not limited in this embodiment.
The heat energy comprehensive utilization system based on the composite air conditioner provided by the embodiment has the following advantages:
