Problems solved by technology
[0006] Since the inner chamber of the compressor 13 will generate periodic pressure pulsations during the refrigeration / heating cycle, therefore, in the above two cases, the periodic pressure pulsations will directly act on the spool of the solenoid valve 12, The spool of the solenoid valve 12 is pushed back and reset repeatedly, resulting in periodic abnormal mechanical noises in the air-supplementing and enthalpy-enhancing air conditioning system
In addition, the solenoid valve 12 only has the function of opening and closing, which makes it impossible to flexibly control the amount of air in the air supply circuit

The embodiment of the present invention discloses an air-conditioning system for replenishing air and increasing enthalpy and an air conditioner, which are used to avoid periodic abnormal mechanical noises caused by the periodic pressure pulsation generated in the inner cavity of the compressor, and inability to flexibly Occurrence of the problem of controlling the amount of supplemental air in the supplementary air circuit. The system includes: a compressor, an air supply circuit and a control system; the air supply circuit includes: a flasher and a first electronic expansion valve; one end of the first electronic expansion valve is connected to the air supply port of the compressor, and the The other end of the first electronic expansion valve is connected to the air supply outlet of the flash evaporator; the first electronic expansion valve receives the control command sent by the control system; the first electronic expansion valve is adjusted according to the control command opening. The embodiment of the invention is applicable to the technical field of air conditioning and refrigeration engineering.
Description
technical field [0001] The invention relates to the technical field of air-conditioning and refrigeration engineering, in particular to an air-conditioning system for supplementing air and increasing enthalpy and an air conditioner. Background technique [0002] The supplementary air enthalpy air-conditioning system is widely used because of its ability to improve the cooling / heating effect. Air-enhancing air conditioning system refers to changing the ordinary compressor in the conventional air-conditioning system into a compressor with the function of air-increasing enthalpy (hereinafter referred to as "compressor"), and adding air on the basis of the main circuit The air conditioning system formed after the loop. [0003] Such as figure 1 Shown is a schematic structural diagram of an air-conditioning system for supplementing air and increasing enthalpy. Wherein, the supplementary air loop is made of flash evaporator 11 and solenoid valve 12; the main loop includes compr...
