Abstract

The invention discloses a temperature control method and device and refrigeration equipment, relates to the field of temperature control and is used for reducing power consumption and noise of a compressor. The temperature control method comprises the following steps: acquiring first power, first output voltage and second power; the first power is the power of the frequency conversion circuit in the first time period, and the first output voltage is the output voltage of the frequency conversion circuit in the first time period; the second power is the power of the frequency conversion circuit in the second time period; predicting a second output voltage according to the first power, the first output voltage and the second power; the second output voltage is used for determining the operation frequency of the compressor in the third time period. According to the temperature control method, when the operation frequency of the compressor is determined, the operation frequency of the compressor is dynamically adjusted according to the power of the frequency conversion circuit, and compared with the condition that the rotation speed of operation of the compressor is a fixed value in the prior art, the power consumption and noise of the compressor can be reduced through the temperature control method.

Description

technical field [0001] The invention relates to the field of temperature control, in particular to a temperature control method, device and refrigeration equipment. Background technique [0002] At present, home appliances such as frequency conversion refrigerators or frequency conversion freezers usually include frequency conversion circuits. The frequency conversion circuit is connected with the temperature controller and the compressor. When the frequency conversion circuit recognizes that the thermostat is closed, the frequency conversion circuit can control the operation of the compressor, thereby controlling the temperature of the frequency conversion refrigerator or the frequency conversion freezer. [0003] However, the rotational speed at which the compressor operates is usually a fixed value, and the high rotational speed will result in large power consumption of the compressor and high noise of the compressor. Contents of the invention [0004] The invention p...
