Heating ventilation air conditioning system, control method, device and apparatus thereof, and storage medium

Abstract

The invention relates to a heating ventilation air conditioning system, a control method, device and apparatus thereof, and a storage medium. The control method comprises the steps that load change information of the heating ventilation air conditioning system is determined; whether the operation number of units in the heating ventilation air conditioning system is adjusted or not is determined according to the load change information; if it is determined that the operation number of the units in the heating ventilation air conditioning system is adjusted, whether operation information of theheating ventilation air conditioning system meets the preset unit adjusting condition or not is judged; and if the operation information of the heating ventilation air conditioning system meets the unit adjusting condition, the start-stop state of a target unit in the heating ventilation air conditioning system is adjusted, and thus the phenomenon that unit start-stop is improper, or the number ofthe operating units cannot be adjusted in time when user demands are changed is avoided. By adopting the technical scheme, it can be ensured that the output capacity of the heating ventilation air conditioning system is met under reasonable energy consumption, and the service life of the units in the air conditioning system is prolonged.

Description

technical field [0001] The present invention relates to the technical field of HVAC systems, in particular to an HVAC system and its control method, device, equipment and storage medium. Background technique [0002] With the improvement of people's living and working standards, more and more air-conditioning systems have been put into use. Among them, the application of HVAC systems using water as a cold and heat source is becoming more and more extensive. [0003] The unit in the HVAC system is the single device with the largest energy consumption, and the general HVAC system is composed of multiple units. In the existing technology, users often start the required number of units according to their needs. However, various reasons often lead to improper start and stop of the unit or changes in user needs, resulting in the inability to adjust the number of operating units in time, which may cause the problems of high energy consumption and insufficient output capacity of th...
