Air conditioner with double heat exchangers and control method thereof

Abstract

The invention relates to the technical field of refrigeration, and discloses an air conditioner with double heat exchangers and a control method thereof. The air conditioner with the double heat exchangers comprises a compressor, a reversing device, an outdoor heat exchanger, a first heat exchanger, a first throttling device and a second heat exchanger which are sequentially connected through pipelines. One end of the second heat exchanger is connected with the reversing device through a pipeline, the first throttling device and the second heat exchanger are connected with a first adjusting valve in parallel, and the first throttling device and the first heat exchanger are connected with a second adjusting valve in parallel. According to the air conditioner, refrigerant distribution of the two heat exchangers can be adjusted according to actual needs, unnecessary refrigerant flow is reduced, energy saving is facilitated, meanwhile, dehumidification can be carried out under the condition that cooling is not carried out, and the implementation mode is simple and reliable.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to an air conditioner with double heat exchangers and a control method thereof. Background technique [0002] In order to meet the temperature regulation needs of large spaces, there are air conditioners with multiple air outlets on the market, such as an air conditioner with two air outlets respectively connecting the living room and the dining room. An air conditioner with multiple air outlets can usually only distribute the same cooling capacity to different air outlets, and cannot freely adjust the cooling capacity distribution. However, due to the different time when people move in different spaces (such as dining room and living room), the required cooling capacity The quantity is inconsistent, resulting in inaccurate cold delivery, which is easy to cause energy waste. In order to solve this problem, some air conditioners adopt the method of adjusting the amount of refr...

Problems solved by technology

An air conditioner with multiple air outlets can usually only distribute the same cooling capacity to different air outlets, and cannot freely adjust the cooling capacity distribution. However, due to the different time when people move in different spaces (such as dining room and living room), the required cooling capacity The quantity is not consistent, resulting in inaccurate cold delivery, which is easy to cause energy waste

In order to solve this problem, some air conditioners adopt the method of adjusting the amount of refrigerant distributed to different heat exchangers, but the existing adjustment method is relatively complicated, which brings additional costs, and improper settings are prone to reliability problems such as liquid return

At the same time, when the existing air conditioners dehumidify, they usually use cooling methods to condense the moisture in the indoor air, and the indoor temperature will drop significantly while dehumidifying, which cannot meet the needs of users for dehumidification alone.
