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 refrigeration-only air conditioner and a control method of the refrigeration-only air conditioner. The refrigeration-only air conditioner comprises a double-cylinder compressor, an outdoor heat exchanger and an indoor heat exchanger assembly. The double-cylinder compressor comprises a shell, a first air cylinder and a second air cylinder, and the value of the volume ratio of the first air cylinder to the second air cylinder ranges from one to twenty. The outdoor heat exchanger is provided with a flow-in port and two flow distribution ports. The indoor heat exchanger assembly comprises a first indoor heat exchange portion and a second indoor heat exchange portion, wherein the two ends of the first indoor heat exchange portion are connected with a first air suction portion and one of the flow distribution ports respectively, the two ends of the second indoor heat exchange portion are connected with a second air suction portion and one of the flow distribution ports respectively, a throttling element is arranged between the first indoor heat exchange portion and the outdoor heat exchanger in series, and a throttling element is arranged between the second indoor heat exchange portion and the outdoor heat exchanger in series. The refrigeration-only air conditioner is high in level of energy efficiency, and good in effect of energy saving.

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...
