Abstract

The invention discloses a heat pump system control method, comprising: detecting the outlet water temperature of a unit in the heat pump system in real time; judging whether the outlet water temperature is greater than a preset temperature threshold, and if so: generating a first control signal based on the first A control signal reduces the operating frequency of the fan in the heat pump system until the outlet water temperature is lower than a preset temperature threshold. The invention can effectively solve the protection problem of the unit due to high outlet water temperature of the unit due to engineering abnormality, thereby improving the reliability of the unit. The invention also discloses a heat pump system control device.

Description

technical field [0001] The invention relates to the technical field of heat pump control, in particular to a heat pump system control method and device. Background technique [0002] At present, as people's requirements for environmental protection are getting higher and higher, the energy-saving and environmental protection features of heat pump water heaters make them more and more popular among users. Due to the relatively high installation requirements of large-scale heat pump projects, the non-standard installation of many projects leads to the selection of project water pumps or water pipes is too small, which in turn causes the outlet water temperature of the unit to exceed the range of the unit. It is easy to cause damage to the unit. Contents of the invention [0003] The invention provides a control method for a heat pump system, which can effectively solve the protection problem of the unit due to high outlet water temperature of the unit due to engineering abn...
