Abstract

The invention discloses a control method and an air conditioning system. The air conditioning systems comprises an outdoor unit, and the outdoor unit comprises a plurality of external heat exchangers.The control methods comprises the steps: when the air conditioning system operates, the number of the currently started external heat exchangers is determined; the exhaust pressure and exhaust overheating degree of the air conditioning system, or the exhaust overheating degree, the system temperature and the outdoor ambient temperature are obtained; and the number of the started external heat exchangers is adjusted according to the number of the currently started external heat exchangers, the exhaust pressure and the exhaust overheating degree, or according to the number of the currently started external heat exchangers, the exhaust overheating degree, the system temperature and the outdoor ambient temperature. The operation state of the external heat exchangers is adjusted according to the actual needs of the air conditioning system for the external heat exchangers, and thus reliable and stable operation of the air conditioning system can be guaranteed; and thus, the air conditioningsystem can flexibly meet the actual using needs, and meanwhile the reliability of system operation is guaranteed.

Description

technical field [0001] The invention relates to the technical field of air conditioning equipment, in particular to a control method and an air conditioning system. Background technique [0002] In the related art, an air conditioning system is a device for cooling and heating indoor spaces, such as interior spaces of houses, restaurants and offices. In order to efficiently cool and heat an indoor space divided into several rooms, an air conditioning system that cools and heats each room simultaneously and independently has been developed. Specifically, a plurality of indoor units are connected to one outdoor unit, and the indoor units are installed in respective rooms. Each indoor unit operates in a cooling mode, or operates in a heating mode, and regulates the temperature of the air in the indoor space. However, due to the different occasions where the air conditioning system is used, there will be low-temperature refrigeration, even ultra-low temperature refrigeration, ...
