Problems solved by technology

[0002] Generally, when the air conditioner is cooling, the refrigerant throttled by the throttling element directly enters the indoor heat exchanger for heat exchange. Since the throttled refrigerant is mixed with a part of gaseous refrigerant, it enters the indoor heat exchanger. The gaseous refrigerant not only affects the heat exchange effect of the indoor heat exchanger, but also increases the compression power consumption of the compressor and reduces the energy efficiency ratio of the compressor, thus affecting the energy efficiency level of the air conditioner.

Abstract

The invention discloses a single cooling type air conditioner and a control method. The single cooling type air conditioner comprises a double-cylinder compressor, an outdoor heat exchanger assembly and an indoor heat exchanger assembly, wherein the double-cylinder compressor comprises a shell, a first cylinder and a second cylinder; the value range of the volume ratio of the first cylinder to the second cylinder is 1 to 20; a first end of a first outdoor heat exchange part and a first end of a second outdoor heat exchange part of the outdoor heat exchanger assembly are connected with an exhaust hole; the two ends of a first indoor heat exchange part of the indoor heat exchanger assembly are respectively connected with a first air suction hole and a second end of the first outdoor heat exchange part; the two ends of a second indoor heat exchange part are respectively connected with a second air suction hole and a second end of the second outdoor heat exchange part; and a throttling element is in series connection between the first indoor heat exchange part and the first outdoor heat exchange part and between the second indoor heat exchange part and the second outdoor heat exchange part. According to the single cooling type air conditioner, the energy efficiency level is high, and the energy saving effect is good.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a cooling-only air conditioner capable of improving the energy efficiency of the air conditioner and a control method. Background technique [0002] Generally, when the air conditioner is cooling, the refrigerant throttled by the throttling element directly enters the indoor heat exchanger for heat exchange. Since the throttled refrigerant is mixed with a part of gaseous refrigerant, it enters the indoor heat exchanger. The high gaseous refrigerant not only affects the heat exchange effect of the indoor heat exchanger, but also increases the compression power consumption of the compressor and reduces the energy efficiency ratio of the compressor, thus affecting the energy efficiency level of the air conditioner. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. For this...
