Abstract

The invention provides an air conditioning system and an air conditioning system control method. The air conditioning system comprises a compressor, a four-way valve, an indoor heat exchanger and outer heat exchangers. The outdoor heat exchangers comprise the first outdoor heat exchanger and the second outdoor heat exchanger which are independently arranged. Moreover, when the air conditioning system conducts refrigeration operation, the first outdoor heat exchanger and the second outdoor heat exchanger are used as condensers, and the indoor heat exchanger is used as an evaporator. When the air conditioning system conducts heating operation, the first outdoor heat exchanger and the second outdoor heat exchanger are used as evaporators, and the indoor heat exchanger is used as a condenser. When the air conditioning system conducts defrosting operation, one outdoor heat exchanger is used as a condenser, the other outdoor heat exchanger is used as an evaporator, and the indoor heat exchanger is used as a condenser. The outdoor heat exchangers are divided into two parts, and normal heating of an inner machine during defrosting is guaranteed.

Description

technical field [0001] The invention relates to the field of air-conditioning equipment, in particular to an air-conditioning system and a control method for the air-conditioning system. Background technique [0002] Currently, air conditioning systems usually have both heating and cooling functions. When the air-conditioning system is in heating operation, due to the low outdoor temperature, frost will form on the surface of the outdoor heat exchanger, and after frosting, the heat transfer will deteriorate, the frost layer will thicken rapidly, and the heating capacity of the system will rapidly decay. Therefore, the air-conditioning system needs to be defrosted regularly . [0003] The traditional defrosting method is to use a four-way valve to change direction, and the system changes from a heating cycle to a refrigeration cycle. At this time, the heat exchanger of the external unit becomes a condenser, and the high-temperature and high-pressure gas is used to quickly me...
