Abstract

The invention is suitable for the technical field of energy, and provides a method and a device for monitoring the condensation approaching temperature of an electric refrigerator in real time. The method comprises the steps that the real-time condensation saturation temperature of a refrigerant is obtained; the real-time outlet temperature of cooling water of a condenser is obtained; the real-time load percentage of an electric refrigerator is obtained; based on the load percentage, a condensation approaching temperature calculation formula is obtained; and based on the condensation saturation temperature, the outlet temperature, the load percentage and the condensation approaching temperature calculation formula, the condensation approaching temperature is determined, and the condensation approaching temperature is displayed. The condensation approaching temperature is calculated by obtaining the condensation saturation temperature, the cooling water outlet temperature and the load percentage, so that the condensation approaching temperature is monitored in real time, and a prompt can be given for abnormal heat exchange of the condenser.

Description

technical field [0001] The invention belongs to the field of energy technology, in particular to a method and device for real-time monitoring of the condensation approach temperature of an electric refrigerator. Background technique [0002] In the evaluation parameters of electric refrigerators, the heat transfer effect of the condenser is often evaluated by the approximation of the condensation temperature. When the condensing temperature approach is higher than the reasonable range, it often means that the heat transfer effect of the condenser is poor, which may be caused by the dirty blockage of the condenser affecting the efficiency of the refrigerator. If the customer is not reminded to clean in time, the scale inside will accumulate more and more, causing the water system to be affected accordingly, which will affect the operation effect of the air conditioning system; it will also cause the refrigerator to run at low efficiency for a long time, thus As a result, the...
