Problems solved by technology

[0002] When the existing double-row heat exchanger (composed of the first heat exchanger and the second heat exchanger in series) is used as an evaporator, the refrigerant flows through the first heat exchanger and the second heat exchanger in sequence, and the refrigerant First, after heat exchange in the first heat exchanger, a gas-liquid two-phase refrigerant is formed, and the heat transfer efficiency of the gas-liquid two-phase refrigerant is low, resulting in low heat transfer efficiency of the refrigerant in the second heat exchanger

Abstract

The invention relates to the field of air conditioners. A heat exchanger assembly comprises a first heat exchanger, a second heat exchanger, a first valve, a second valve and a gas-liquid separator. The two ends, in the refrigerant circulation direction, of the first heat exchanger are provided with a first connector and a second connector correspondingly. The two ends, in the refrigerant circulation direction, of the second heat exchanger are provided with a third connector and a fourth connector correspondingly. The first connector and the third connector are in communication through a firstpipeline, and the first valve is arranged on the first pipeline. The first connector and the gas-liquid separator are in communication through a second pipeline, a liquid outlet of the gas-liquid separator communicates with the third connector through a third pipeline, and the second valve is arranged on the second pipeline or the third pipeline. Due to the arrangement of the gas-liquid separator, when the heat exchanger assembly serves as an evaporator to be used, the evaporation efficiency is higher, and the heat exchange efficiency of the heat exchanger assembly is higher; and when the heat exchanger assembly serves as a condenser to be used, the gas-liquid separator does not influence refrigerant circulation from the second heat exchanger to the first heat exchanger.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to a heat exchanger assembly and an air conditioner. Background technique [0002] When the existing double-row heat exchanger (composed of the first heat exchanger and the second heat exchanger in series) is used as an evaporator, the refrigerant flows through the first heat exchanger and the second heat exchanger in sequence, and the refrigerant First, after heat exchange in the first heat exchanger, a gas-liquid two-phase refrigerant is formed, and the heat transfer efficiency of the gas-liquid two-phase refrigerant is low, resulting in low heat transfer efficiency of the refrigerant in the second heat exchanger . Contents of the invention [0003] One of the objectives of the present invention is to provide a heat exchanger assembly with high heat exchange efficiency. [0004] In order to achieve the above object, the heat exchanger assembly provided by the present invention ...
