Operation control method and device, storage medium and multi-split system

Abstract

The invention discloses an operation control method and device, a storage medium and a multi-split system. The method comprises the steps that the outdoor environment temperature, the target temperature and the indoor environment temperature of the multi-split system are obtained; the multi-split system is a cascade circulation system and comprises a first temperature level circulation system anda second temperature level circulation system; the operation working conditions of the multi-split system are determined according to the outdoor environment temperature and comprise the first set working condition, the second set working condition and/or the third set working condition; under the determined operation working conditions, the operation modes of the multi-split system are determinedaccording to the target temperature and comprise the first set mode, the second set mode, the third set mode, the fourth set mode and/or the fifth set mode; and under the determined operation modes,the operation process of the multi-split system is controlled according to the indoor environment temperature. According to the scheme, the problem that the comfort requirements of users under different environments cannot be met can be solved, and the effect of meeting the comfort requirements of the users under different environments can be achieved.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to an operation control method, device, storage medium and multi-connection system, in particular to an ultra-high temperature cascade central multi-connection system and an operation control method, device and storage medium of an energy utilization mode and multi-line systems. Background technique [0002] The functions of some household water machines are relatively old, and the internal and external units cannot be linked together. They only provide a fixed water temperature for cooling, which is less comfortable. Some multi-connected units use refrigerant as the refrigerant to achieve indoor cooling or heating effects, but the temperature difference of the outlet air of this kind of multi-connected units is relatively large, the operation process is unscientific, and the energy saving performance is poor, especially bad usage habits are more likely to cause...
