Description

Technical Field

[0001] The present application relates to the technical field of water heater testing devices, and in particular to a water tank temperature simulation device. Background Art

[0002] When testing circulating heat pump water heaters, since the standard water tank is generally located in the laboratory equipment room, the water tank temperature sensor that comes with the heat pump can only be placed in the laboratory, and the water tank temperature cannot be accurately monitored, which has an adverse effect on the entire operation process of the heat pump. Using this device, the real-time water tank temperature value of the heat pump during laboratory operation can be simulated, thereby improving the test accuracy and ensuring that the heat pump operates according to the factory preset working conditions; most of the existing tests place the heat pump water tank temperature sensor in the laboratory environment. Since the laboratory environment is constant, the water tank temperature value monitored by the heat pump is also constant, but in fact the water tank temperature value will continue to increase with the operation of the heat pump. Especially for variable frequency heat pumps, the size of the water tank temperature is an important reference for the adjustment of the prototype parameters; some laboratories will place the water tank temperature sensor in the standard water tank of the laboratory, but due to the deviation of the sensor temperature value, the prototype will be shut down before reaching the laboratory specified temperature, which seriously affects the test results.
