Abstract

The invention provides an air conditioner heat exchange system and a control method thereof. Cold accumulation heat exchangers for cooling ordinary water to a supercooling state (supercooled water below zero) are added in the air conditioner heat exchange system; particularly, when the air conditioner heat exchange system is in a heating mode, the cold accumulation heat exchangers are in parallel connection with two ends of an outdoor heat exchanger so as to absorb and store part of refrigerating capacity, and the aims of delaying system frosting and prolonging heating time are achieved; and when the air conditioner heat exchange system is in a refrigeration mode, the cold accumulation heat exchangers are in series connection between the outdoor heat exchanger and a restrictor so as to release the refrigerating capacity stored in the cold accumulation heat exchangers, and the aims of increasing the refrigerating capacity, achieving supercooling of the system and reducing power are achieved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to an air-conditioning heat exchange system and a control method thereof. Background technique [0002] During the use of current heating and cooling air conditioners, when the air conditioner operates in the cooling mode, the heat exchange system of the air conditioner is prone to insufficient subcooling, which leads to insufficient capacity of the air conditioner heat exchange system. For example, in the multi-connected system, there are long piping, high drop and multiple evaporators, and the uneven flow of refrigerant is very serious, resulting in low efficiency of the multi-connected system. Contents of the invention [0003] In view of this, it is necessary for the present invention to provide an air-conditioning heat exchange system to effectively solve the aforementioned problem of insufficient subcooling in cooling mode and reduce power consumption of the air...
