Control method and air conditioning system for controlling operation of air conditioning system

Abstract

The invention relates to a control method for controlling the operation of an air conditioner system and the air conditioner system. According to one embodiment of the invention, the control method for controlling the operation of the air conditioner system (AC) is provided. The air conditioner system (AC) comprises a first heat exchanger (10) and second heat exchangers (30) which are arranged in a circulating loop (CL) of the air conditioner system (AC); and when flowing through the first heat exchanger (10), working fluid in the circulating loop (CL) absorbs heat, but when flowing through the second heat exchangers (30), the working fluid releases heat. The control method comprises the following steps: detection of the first heat exchanger, namely detecting operation parameters of the first heat exchanger (10), and adjustment of the second heat exchangers, namely adjusting the operation of the second heat exchangers (30) according to the operation parameters of the first heat exchanger (10); and therefore, the operation parameters of the first heat exchanger (10) are changed into a preset parameter range. According to the control method, the freezing resistance and / or the refrigeration property adjustment performance of the air conditioner system can be improved.

Description

technical field [0001] The present invention relates to the field of air conditioning, in particular to a control method for controlling the operation of an air conditioning system and an associated air conditioning system that improve the antifreezing and / or cooling capacity adjustment of the air conditioning system. Background technique [0002] Under the condition of low ambient temperature, the reliability of the air conditioning system using the compression refrigeration cycle is poor due to the influence of the environment. At this time, an air conditioning system with a natural cooling cycle can usually be used to provide cooling. In an air conditioning system with a natural cooling cycle, the refrigerant (working fluid) is condensed in, for example, a fin heat exchanger, thereby exchanging heat with the environment and transferring heat to the environment. Afterwards, the refrigerant is pressurized by the refrigerant pump and then enters, for example, the shell-and-...

AI Technical Summary

Problems solved by technology

However, since the air-conditioning system with a natural cooling cycle loop is used to provide cooling, the ambient temperature is low, so the temperature of the refrigerant entering the shell-and-tube heat exchanger is also low, so there is a risk of freezing and cracking the heat exchange tubes
