Abstract

The invention belongs to the field of refrigeration appliances, in particular to a control method and control system for condenser temperature protection. The control method for the condenser temperature protection comprises the following steps that real-time temperature of a condenser is detected by a temperature sensor, sampling is performed on obtained temperature data by a sampling unit according to a sampling period, the temperature data are transmitted to a main control unit, and the main control unit controls the operation state of a compressor according to the change rate of the temperature data; when the rising speed of the temperature of the condenser is judged to be too high, the compressor is controlled to be closed down; if the rising speed of the temperature of the condenser is not out of a normal range, the compressor is controlled to be operated normally. Accordingly, the temperature change of the condenser can be monitored in real time, the operation state of the compressor can be controlled through the change rate of the temperature data, the misinformation rate is reduced, and the stability and reliability of a refrigeration system are improved.

Description

technical field [0001] The invention belongs to the field of refrigeration household appliances, and in particular relates to a control method and a control system for condenser temperature protection. Background technique [0002] For high-power refrigeration appliances such as air conditioners and refrigerators, their safety and reliability are issues that researchers are very concerned about. During the refrigeration process, the refrigerant releases heat in the condenser, which will cause the temperature of the condenser to continue to rise. Long-term operation of the condenser at excessively high temperature will affect its own life, and even cause fire, leakage and other safety accidents. [0003] At present, the general practice is to set high temperature protection on the condenser, that is, install temperature sensitive elements on the condenser. When the temperature exceeds a fixed value, the main control unit sends a signal to control the compressor to stop, and...
