Abstract

The invention discloses a control method of an air conditioning system. The air conditioning system comprises an outdoor heat exchanger and a throttling component. The control method comprises the steps of detecting the outlet temperature of the outdoor heat exchanger when the air conditioning system enters the defrosting mode; judging the outlet temperature of the outdoor heat exchanger when the condition of exiting the defrosting mode of the air conditioning system is met; beginning timing when the outlet temperature of the outdoor heat exchanger is higher than the preset temperature and controlling the air conditioning system to enter the heat generation mode when the accumulated time is longer than the preset time. According to the control method of the air conditioning system, the problem that the air conditioning system operates abnormally when the output power of the air conditioning system is too low in the heat generation process can be solved, and the air conditioning system can operate stably and reliably. The invention further discloses a control device of the air conditioning system.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a control method of an air conditioning system and a control device of the air conditioning system. Background technique [0002] At present, the destruction of the ozone layer and global warming have become increasingly serious global environmental problems, and the refrigerants R22 and R410A commonly used in the refrigeration industry will have an impact on the environment. [0003] Due to the excellent environmental friendliness of hydrocarbon refrigerants HCs, that is, low GWP (Global Warming Potential, global warming potential value) and ODP (Ozone Depletion Potential, ozone depletion potential value) is 0, more and more applications in refrigeration in the industry. With the use of HCs refrigerants in compressors, there are still many problems to be solved. For example, under low-temperature heating conditions, the output power is too low after defrosting and heat...
