Problems solved by technology

[0002] The current air-conditioning refrigeration system does not optimize the cycle design of the gaseous refrigerant after throttling and before entering the evaporator, which causes the gaseous refrigerant to affect the heat transfer performance of the evaporator and increase the compression power consumption of the compressor, thus affecting the energy efficiency of the air conditioner
Air injection enthalpy increase and two-stage compression technology can improve the heating capacity of the air conditioning system at low and ultra-low temperatures, but for the cooling conditions often used by air conditioners, the energy efficiency improvement is very limited

Abstract

The invention discloses a single-refrigeration type air conditioner and a control method thereof.The air conditioner comprises a double-cylinder compressor, an outdoor heat exchanger, an indoor heat exchanger, a gas-liquid separator and a cold medium cooler.The gas suction opening of a first cylinder is communicated with a first liquid storage device.The exhaust volume ratio of a second cylinder to the exhaust volume ratio of the first cylinder ranges from 1% to 10%.The gas-liquid separator comprises a gas outlet, a first connector and a second connector.The gas outlet is connected with the second cylinder.A first throttling element for fixing the opening degree is connected between the first connector and the outdoor heat exchanger in series.A second throttling element for fixing the opening degree is connected between the second connector and the indoor heat exchanger in series.The cold medium cooler is connected between the first throttling element and the first connector in series, or the cold medium cooler is connected between the second throttling element and the second connector in series.The efficiency of the single-refrigeration type air conditioner is effectively improved.

Description

technical field [0001] The invention relates to the refrigeration field, in particular to a cooling-only air conditioner and a control method thereof. Background technique [0002] The current air-conditioning refrigeration system does not optimize the cycle design of the gaseous refrigerant after throttling and before entering the evaporator, which causes the gaseous refrigerant to affect the heat transfer performance of the evaporator and increase the compression power consumption of the compressor, thus affecting the energy efficiency of the air conditioner . Air injection enthalpy increase and two-stage compression technology can improve the heating capacity of the air conditioning system at low and ultra-low temperatures, but the energy efficiency improvement is very limited for cooling conditions where air conditioners are often used. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a...
