Multi-split heat pump system, control method thereof and computer readable storage medium

Abstract

The invention discloses a control method of a multi-split heat pump system. The multi-split heat pump system comprises a compressor, at least one hydraulic module and at least one air conditioner indoor unit, wherein the at least one hydraulic module and the at least one air conditioner indoor unit are both connected with the compressor. The method comprises the steps that first energy demand information of the at least one air conditioner indoor unit and second energy demand information of the at least one hydraulic module are obtained; the first energy demand information represents the heating capacity demand condition of the at least one air conditioner indoor unit, and the second energy demand information represents the heating capacity demand condition of the at least one hydraulic module; and the operation frequency of the compressor is adjusted according to target parameters corresponding to the first energy demand information and the second energy demand information. The invention further discloses the multi-split heat pump system and a computer readable storage medium. According to the multi-split heat pump system, the control method thereof and the computer readable storage medium provided by the invention, the output capacity of the compressor is accurately matched with the actual indoor heat exchange requirement, and indoor environment temperature adjustment and hydraulic module heat supply are effectively considered.

Description

technical field [0001] The present invention relates to the technical field of multi-connection heat pump systems, and in particular to a control method of a multi-connection heat pump system, a multi-connection heat pump system and a computer-readable storage medium. Background technique [0002] With the development of economy and technology, multi-connected heat pump systems are more and more widely used in daily life. For example, the air source heat pump adds a hydraulic module to provide capillary floor radiant heating, radiator heating, etc., and can also provide a heat source for the domestic water storage tank. [0003] At present, in a multi-connected system with an indoor air duct unit and a hydraulic module, the operating frequency of the outdoor compressor is generally adjusted according to the preset fixed exhaust pressure or the temperature in the middle of the coil of the air duct inner unit, which is easy. The output capacity of the compressor does not matc...

Problems solved by technology

[0003] At present, in a multi-connected system with an indoor air duct unit and a hydraulic module, the operating frequency of the outdoor compressor is generally adjusted according to the preset fixed exhaust pressure or the temperature in the middle of the coil of the air duct inner unit, which is easy. The output capacity of the compressor does not match the actual heat exchange demand in the room, resulting in the inability to effectively balance the indoor environment temperature regulation and the heat supply of the hydraulic module
