Problems solved by technology

[0002] In the existing air conditioning system, the flow direction of the refrigerant in the outdoor heat exchanger is different during cooling and heating, and the heat exchange effect of the outdoor heat exchanger is best only when the flow direction of the refrigerant is in the opposite direction to the wind direction. The flow direction of the refrigerant in the outdoor heat exchanger is different when it is hot, so that there is only one case in which the flow direction of the refrigerant in the outdoor heat exchanger is opposite to the wind direction during cooling and heating, which causes the existing air conditioning system to focus on heating when the cooling effect is The effect will be worse, and the cooling effect will be worse when the heating effect is emphasized. For this reason, in the prior art, it is usually to find the balance point of the cooling and heating effects to adjust the flow path so that the cooling and heating effects are balanced. But this leads to the cooling effect and heating effect of the air conditioning system can not reach the optimal state

Abstract

The invention provides an air conditioner and a heat exchange system thereof. The heat exchange system of the air conditioner comprises a closed pipeline formed by a compressor, a four-way valve, an outdoor heat exchanger, a throttling device and an indoor heat exchanger in sequential arrangement. Refrigerant flows in the closed pipeline, and a reversing device is arranged between an inlet and an outlet of the outdoor heat exchanger to enable same flowing direction of the refrigerant in the outdoor heat exchanger when the heat exchange system of the air conditioner is in a refrigerating status and a heating status. Owing to the reversing device is arranged between the inlet and the outlet of the outdoor heat exchanger, flowing directions of the refrigerant in the outdoor heat exchanger are same and both opposite to the air direction when the heat exchange system of the air conditioner is in the refrigerating status and the heating status, heat exchange effects of the outdoor heat exchanger are guaranteed to be always optimal, refrigerating and heating effects of the heat exchange system of the air conditioner are improved, energy efficiency in refrigerating and heating is improved, and accordingly service quality of the air conditioner is improved.

Description

technical field [0001] The invention relates to the field of household appliances, and more specifically, to an air conditioner heat exchange system and an air conditioner. Background technique [0002] In the existing air conditioning system, the flow direction of the refrigerant in the outdoor heat exchanger is different during cooling and heating, and the heat exchange effect of the outdoor heat exchanger is best only when the flow direction of the refrigerant is in the opposite direction to the wind direction. The flow direction of the refrigerant in the outdoor heat exchanger is different when it is hot, so that there is only one case in which the flow direction of the refrigerant in the outdoor heat exchanger is opposite to the wind direction during cooling and heating, which causes the existing air conditioning system to focus on heating when the cooling effect is The effect will be worse, and the cooling effect will be worse when the heating effect is emphasized.
