Embodiment Construction

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0014] see figure 1 . An air conditioning system with subcooling comprises a low pressure liquid storage tank 24, a compressor 1, an oil separator 2, a four-way valve 3, an outdoor heat exchanger 4, a subcooling heat exchange device 18, a first outdoor electronic expansion device connected in sequence Valve 6 , high pressure liquid storage tank 7 , second outdoor electronic expansion valve 8 and indoor heat exchanger 9 .

[0015] The top of the subcooling heat exchange device 18 is provided with a condensate water inlet 17 that communicates with the indoor unit condensate pipe 12, and the lower portion is provided with a condensate water outlet 20 whose opening is slightly smaller than the water inlet. The position of the condensate water outlet 20 is slightly lower than the level of the subcooling coil 5 arranged in the subcooling heat exchange device 1...

Abstract

The invention discloses an air conditioning system with super cooling, which comprises a low-pressure liquid storage tank, a compressor, an oil separator, a four-way valve, an outdoor heat exchanger, a super cooling heat transfer device, a first outdoor electronic expansion valve, a high pressure liquid storage tank, a second outdoor electronic expansion valve and an indoor heat exchanger, wherein the super cooling heat transfer device comprises a condensate water inlet, a condensate water overflow port, a condensate water drainage port, a drain outlet and a super cooling coil, one or more indoor unit condensate water drain pipes are arranged between an indoor unit and the super cooling heat transfer device, and the indoor unit condensate water drain pipes which come out from an indoor unit pressure water container enter the condensate water inlet of an outdoor unit super cooling heat exchange device after being connected in parallel. Refrigerant circulation of the air conditioning system is consistent with a traditional air conditioning refrigerant system. The air conditioning system with super cooling has the advantages of simple and reasonable structure, high work efficiency, obvious effect, and wide scope of application.

Description

technical field [0001] The present invention relates to an air conditioning system with supercooling. Background technique [0002] At present, common air conditioners use the outdoor unit condenser several long U pipes to set air-cooled high-temperature and high-pressure refrigerant at the outlet of the condenser, or use a low-pressure tank as a regenerative device to cool the high-temperature and high-pressure refrigerant at the condenser outlet. There is also a separate regenerator (plate exchange or sleeve) to realize the supercooling of the high temperature and high pressure refrigerant at the condenser outlet and the superheating of the return gas. There are also manufacturers who use the condensed part of the refrigerant to first throttle and then use it to cool the remaining condenser outlet refrigerant. These air-conditioning systems with supercooling can, to a certain extent, have the effect of re-cooling the high-temperature and high-pressure refrigerant at the o...
