Abstract

The invention discloses an air conditioning system control method and device and an air conditioning system. The method comprises the steps that the indoor environment temperature and a user set temperature of the air conditioning system are obtained; the difference value between the indoor environment temperature and the user set temperature is determined; and the evaporating pressure or saturation temperature corresponding to the condensing pressure of the air conditioning system is controlled according to the operation mode and the difference value of the air conditioning system. According to the scheme, the defects of poor energy saving effect, inconvenient application, poor user experience and the like in the prior art can be overcome, and the beneficial effects of good energy saving effect, convenient application and good user experience are achieved.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a control method and device for an air conditioning system and an air conditioning system, in particular to a control method for an energy-saving operation multi-connected air conditioning system, a device corresponding to the method, and a multi-connected device with the device Air Conditioning System. Background technique [0002] Multi-connected central air conditioner is a type of household central air conditioner, commonly known as "one-to-many", which means that one outdoor unit is connected to two or more indoor units through piping. A primary refrigerant air conditioning system in the form of direct evaporative heat exchange. [0003] The current multi-connected air conditioning system will control a constant evaporating pressure or condensing pressure in order to achieve a certain cooling or heating effect during cooling and heating operations, but ...
