Suitable operating mode is changed to, intelligence degree is higher, especially suitable for large-scale multi-gang air conditioner, to further increase air-conditioning
Annual Energy Efficiency Ratio, reduce the energy consumption of air-conditioning.
By taking embodiment illustrated in fig. 3 as an example, cyclic process of the air-conditioning system under different refrigeration work modes is as follows:
When outdoor temperature is higher or indoor/outdoor temperature-difference is smaller, air-conditioning system runs on compressor mode, compressor 10, section
Fluid element 30, water pump 50, the first valve port 81 of the first triple valve and the second valve port 82, the second valve port 92 of the second triple valve and
Three valve ports 93 are opened, and the third valve port 83 of the first triple valve, the first valve port 91 of the second triple valve are closed.At this point, refrigerant is logical
Overcompression machine 10 is compressed into 21 access of refrigerant after high temperature and high pressure gas by check valve 150 into condenser 20, refrigeration
Agent carries out heat exchange with the cooling water in water passage 22 in refrigerant passage 21, condenses heat release into cryogenic high pressure liquid, then into
Enter the throttling of restricting element 30 into low temperature and low pressure liquid, enters in evaporation coil 40 be evaporated heat exchange with room air later, steam
Gaseous refrigerant after hair returns in compressor 10 and completes one cycle.Meanwhile the cooling water flowed out from cooling tower 70 is in water pump
Enter the water passage 22 of condenser 20 under 50 driving, cooling water in water passage 22 with the refrigerant in refrigerant passage 21 into
Row heat exchange, becomes the higher water of temperature, enters back into cooling by the second valve port 92 of the second triple valve and third valve port 93 later
Heat exchange is carried out with outdoor air in tower 70, completes one cycle.
When outdoor temperature is lower or indoor/outdoor temperature-difference is larger, air-conditioning system runs on the cold mode of nature, water pump 50, first
The second valve port 82 and third valve port 83 of triple valve, the first valve port 91 of the second triple valve and third valve port 93 are opened, compressor
10, the second valve port 92 closing of restricting element 30, the first valve port 81 of the first triple valve, the second triple valve.At this point, from cooling tower
The cooling water of 70 outflows enters nature cooling coil 60 under the driving of water pump 50, is evaporated heat exchange with room air, becomes temperature
Higher water is spent, later successively by the first valve of the third valve port 83 of the first triple valve and the second valve port 82, the second triple valve
It is again introduced into cooling tower 70 after mouth 91 and third valve port 93, heat exchange is carried out with outdoor air, completes one cycle.
When outdoor environment is in transition season, air-conditioning system runs on mixed mode, compressor 10, restricting element 30, water
Pump the first valve port 81, the second valve port 82 and the third valve port 83 of the 50, first triple valve, the first valve port 91 of the second triple valve, the
Two valve ports 92 and third valve port 93 are opened.At this point, refrigerant is compressed into after high temperature and high pressure gas by compressor 10 by list
To valve 150 enter condenser 20 refrigerant passage 21, refrigerant in refrigerant passage 21 with the cooling water in water passage 22
Heat exchange is carried out, condensation heat release enters back into the throttling of restricting element 30 into low temperature and low pressure liquid, enter later at cryogenic high pressure liquid
It is evaporated heat exchange with room air in evaporation coil 40, the gaseous refrigerant after evaporation, which returns to, completes once to follow in compressor
Ring.Meanwhile the cooling water flowed out from cooling tower 70 enters the water passage 22 of condenser 20 in the driving next part of water pump 50, it is cold
But water exchanges heat in water passage 22 with the refrigerant in refrigerant passage 21, becomes the higher water of temperature, later by the
The second valve port 92 and third valve port 93 of two triple valves enter back into cooling tower 70 and carry out heat exchange with outdoor air, complete primary
Circulation;Another part enters nature cooling coil 60, is evaporated heat exchange with room air, becomes the higher water of temperature, Zhi Houyi
It is secondary by the third valve port 83 of the first triple valve and the second valve port 82, the second triple valve the first valve port 91 and third valve port 93 after
It is again introduced into cooling tower 70, heat exchange is carried out with outdoor air, completes one cycle.
