Air conditioner

Abstract

The invention discloses an air conditioner and relates to the field of refrigeration. The air conditioner applies to single room of an ordinary family, has high comfort in use and comprises a compressor, a four-way reversing valve, a radiation heat transfer plate, a first throttle mechanism, an indoor heat exchanger, a second throttle mechanism, an outdoor heat exchanger as well as a refrigerant pipeline for connecting all the parts into a loop. The air conditioner further comprises a control valve group used for controlling the flowing direction of a refrigerant, so that the refrigerant in the refrigerant pipeline flows into the radiation heat transfer plate firstly and then flows into the indoor heat exchanger in a refrigerating state and a heating state. With adoption of the air conditioner, the radiation heat transfer plate and the indoor heat exchanger are connected in series and bear the indoor load jointly. Further, by the aid of the control valve group, during cooling or heating, the refrigerant flows into the radiation heat transfer plate firstly and then flows into the indoor heat exchanger, the temperature of the radiation heat transfer plate is guaranteed, and the heat transfer efficiency of the radiation heat transfer plate is improved.

Description

technical field [0001] The invention relates to the refrigeration field, in particular to an air conditioner. Background technique [0002] Air conditioner, also known as air conditioner, air conditioning device. Air conditioners are divided into two categories: traditional household air conditioners and radiant air conditioners. [0003] At present, traditional household air conditioners generally have the problems of strong blowing sensation, high noise, and the wind directly acts on the human body during heating, resulting in poor comfort. [0004] Radiant air-conditioning systems usually used in centralized or semi-centralized cooling / heating systems mostly use cold / hot water as the heat exchange medium, and the temperature and humidity are independently controlled or used in conjunction with other fresh air systems. Due to the disadvantages of the radiant air-conditioning system, such as easy condensation on the surface of the radiant heat exchange plate and small hea...

AI Technical Summary

Problems solved by technology

Due to the shortcomings of the radiant air-conditioning system, such as easy condensation on the surface of the radiant heat exchange plate and small unit heat transfer, there is a large initial investment cost in applying the radiant air-conditioning system to a single room in an ordinary family, and it is impossible to maintain the set temperature of the room. Disadvantages such as closing it at any time, it is generally not applied to a single room in an ordinary family
