摘要
The present invention relates to an apparatus and a method for detecting refrigerant leakage in an air source heat pump system. The method for detecting refrigerant leakage in an air source heat pump system includes the following steps in a cooling mode: S110: obtaining a running parameter of an air source heat pump system, wherein the running parameter at least includes a compressor rotational speed; S120: comparing the running parameter with a preset running parameter range; S130: updating a cumulative score when the running parameter falls within the preset running parameter range; and S140: when the cumulative score exceeds a predetermined cumulative score, determining that refrigerant leakage occurs, and when the cumulative score does not exceed the predetermined cumulative score, return to step S110. The apparatus and method for detecting refrigerant leakage in an air source heat pump system according to the present invention have the advantages of being simple and reliable, easy to implement and convenient to use, and can automatically detect refrigerant leakage, thus improving the running efficiency and safety of modules.
