Clustered heat pump unit control method, device and system and air conditioning equipment

Abstract

The invention relates to a clustered heat pump unit control method, device and system and air conditioning equipment. The method comprises the steps that the first environment temperature of the environment where each unstarted unit is located and the second environment temperature of the environment where each started unit is located are obtained in real time; according to all the first environment temperatures, all the second environment temperatures and a sorting rule corresponding to the current working mode, unstarted unit sorting information and started unit sorting information are determined; if the current running state meets the unit starting condition, heat pump units are controlled to be started according to the unstarted unit sorting information and the target unit sorting information; and according to the current starting number, the maximum starting number, the started unit sorting information and the target unit sorting information of the heat pump units, the target unit sorting information is updated. According to the scheme, the units are sorted according to the real-time environment temperatures of the units, sorting is dynamically corrected, the starting sequence of the heat pump units is controlled according to sorting, and the heat exchange efficiency and the use effect of a heat pump are improved.

Description

technical field [0001] The invention relates to the technical field of heat pump control, in particular to a control method, device, system and air conditioning equipment for clustered heat pump units. Background technique [0002] A heat pump is a high-efficiency energy-saving device that makes full use of low-grade heat energy. It uses a reverse cycle to force heat to flow from a low-temperature object to a high-temperature object. It only consumes a small amount of reverse cycle net work to obtain a large heat supply. It can effectively utilize the low-grade heat energy that is difficult to apply to achieve the purpose of energy saving. [0003] The air conditioning project of a large building requires the installation of a large number of heat pump units. For the convenience of installation and management, the units are usually installed in a specific area to form a cluster of heat pump units. With the increase in the number of heat pump units, long-term acquisition (re...
