Embodiment Construction

[0025] The refrigerator of the present invention comprises a refrigerating system, the refrigerating system comprises a compressor, a chamber electromagnetic valve, a chamber temperature sensor and an ambient temperature sensor, which are respectively connected with a controller, and simultaneously, the controller is connected with a condensing temperature sensor, a power sensor and Return air temperature sensor. Taking a refrigerator with three temperature zones as an example, the chamber solenoid valves include refrigerating chamber solenoid valves, freezer chamber solenoid valves and variable temperature chamber solenoid valves; the chamber temperature sensors include freezer chamber temperature sensors, refrigerator chamber temperature sensors and variable temperature chamber temperature sensors .

[0026] see figure 1 , the control method of the above-mentioned refrigerator comprises the following steps:

[0027] (1). Start the refrigerator with electricity;

[0028] (...

Abstract

Its controller not only is connected with traditional compressor, cavity chamber electromagnetic valve, cavity chamber temperature sensor and ambient temperature sensor in the refrigeration system, but also is connected with condensing temperature sensor, power sensor and return-air temperature sensor, so that in the control process the information of internal temperature of refrigerator, external ambient temperature, condensing temperature, return-air temperature and compressor power, etc. can be monitored, and the optimum working mode can be selected according to the monitored result.

Description

technical field [0001] The invention relates to a refrigerator and a frequency conversion control method of the refrigerator. Background technique [0002] In the current existing technology, traditional refrigerators are matched according to certain standard requirements under specified working conditions, but in practical applications, refrigerators are rarely used under matching working conditions, that is to say, in practical applications The match in the refrigerator is often not optimal. The invention of patent No. 00110830.1 published on July 18, 2001 describes a frequency conversion control method for a refrigerator. on As a benchmark, set up a temperature segment at every interval of an increase range t until it is greater than a fixed maximum temperature point T max So far, each temperature segment corresponds to the working speed N1, N2...N of a compressor max , and then through the temperature sensor to detect the internal temperature T of the refrigerator and...
