Abstract

The invention discloses a control method and device of a heat pump unit. The method comprises the following steps: acquiring an outdoor ambient temperature; determining a frequency regulating parameter according to the outdoor ambient temperature, wherein the frequency regulating parameter is used for regulating and correcting compressor running frequency; utilizing the frequency regulating parameter and the compressor running frequency determined at the last moment to calculate compressor running frequency at the current moment; and controlling a compressor work according to the compressor running frequency at the current moment. The control accuracy of the compressor running frequency is better, and the control precision of indoor ambient temperature is higher.

Description

technical field [0001] The invention relates to the technical field of heat pumps, in particular to a control method and device for a heat pump unit. Background technique [0002] In recent years, the application of heat pump technology in residential heating in winter has become the mainstream. Considering the comfort of water system heating, most of them use heat pump water heaters. Since in the process of practical application, the building envelope and the heating end of the user end are different, how to control the heat pump host to match the heat load required by the building to meet the comfort required by the user has become a major research direction. At present, the control of heat pump units usually takes the outlet water temperature as the control target, and the operating frequency of the compressor is controlled by detecting the outlet water temperature. However, for different building envelope structures and heating terminals, the outlet water temperature is...
