[0039] Based on the first embodiment, in the second embodiment, one end of the third solenoid valve 13 is connected to the outlet of the outdoor heat exchanger 3 in heating mode. When the outdoor ambient temperature further decreases, the amount of refrigerated oil stored in the outdoor heat exchanger 3 increases, so that the refrigerant rich in refrigerated oil in the outdoor heat exchanger 3 cannot efficiently pass through the bottom interface of the outdoor heat exchanger 3 The third solenoid valve 13 , the second solenoid valve 12 and the first solenoid valve 11 enter the compressor 1 . In this embodiment, one end of the third solenoid valve 13 is connected to the outlet of the outdoor heat exchanger 3 in heating mode. When the air conditioner is running in heating mode, the flow direction of the refrigerant is as follows: image 3 As indicated by the middle arrow, the refrigerant rich in refrigerant oil in the outdoor heat exchanger 3 enters into compression from the out...

[0046] Based on the third embodiment, in the fifth embodiment, one end of the third solenoid valve 13 is connected to the bottom interface of the outdoor heat exchanger 3, and one end of the second solenoid valve 12 connected to the third solenoid valve 13 is also connected to the indoor heat exchanger. The middle interface of the heater 4 is connected. In this embodiment, the end of the second solenoid valve 12 connected to the third solenoid valve 13 is also connected to the middle interface of the indoor heat exchanger 4 . When the air conditioner is running in heating mode, if Figure 6 As shown by the middle arrow, the high-temperature and high-pressure refrigerant discharged from the compressor 1 enters the indoor heat exchanger 4 through the first stop valve 9 to complete the heat exchange, and then the refrigerant rich in refrigerant oil in the indoor heat exchanger 4 passes through the second solenoid valve 12, the second A solenoid valve 11 enters the compressor 1 ....

Abstract

The invention discloses an enhanced vapor injection air conditioner. The enhanced vapor injection air conditioner comprises a compressor, a four-way valve, an outdoor heat exchanger, a flash evaporator, an indoor heat exchanger, a first electromagnetic valve, a second electromagnetic valve and a third electromagnetic valve. One end of the third electromagnetic valve is connected with a bottom port or an outlet of the outdoor heat exchanger in a heating mode, the other end of the third electromagnetic valve is connected with one end of the second electromagnetic valve, and the other end of the second electromagnetic valve is connected with one end of the first electromagnetic valve. The invention further discloses a control method of the enhanced vapor injection air conditioner. By means of the enhanced vapor injection air conditioner, a refrigeration-oil-rich refrigerant of the outdoor heat exchanger can enter the compressor through the third electromagnetic valve, the second electromagnetic valve and the first electromagnetic valve, deposition of refrigeration oil in a heating circulating system of the air conditioner is reduced under a low environment temperature, the compressor can be lubricated, and meanwhile the heating efficiency of the air conditioner is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air injection enthalpy increasing air conditioner and a control method thereof. Background technique [0002] Existing air injection enthalpy-increasing air conditioners generally include a compressor, a four-way valve, an outdoor heat exchanger, a flash evaporator, an indoor heat exchanger, a first solenoid valve, and the like. At low ambient temperature, as the outdoor ambient temperature drops, the viscosity of the refrigerant oil in the air-conditioning heating cycle system increases and its solubility decreases, resulting in a large amount of refrigerant oil being stored in the air-conditioning heating cycle system, thereby affecting the heating of the air conditioner performance. In addition, the accumulation of refrigerated oil in the air-conditioning heating cycle system also affects the lubrication effect of the compressor. Contents of the invention [00...
