Problems solved by technology

[0003] However, when heating with an electric heating tape attached to the outer surface of the compressor, a large part of the heat generated by the electric heating tape will be absorbed by the external environment, causing the external temperature of the compressor to be high, while the internal temperature is low, thus making the heating less efficient

Abstract

The invention provides refrigeration equipment and a heating control circuit and a heating control method of a compressor thereof. The heating control circuit is used for controlling the compressor of the refrigeration equipment for heating. The heating control circuit comprises a driving unit and a power supply module. The driving unit is used for controlling the power supply module to supply power to two phases of windings in a winding unit of the compressor in sequence when the refrigeration equipment is in a standby state and receives heating signals so that the winding units are heated, and the compressor is heated. The invention also provides the refrigeration equipment applied to the heating control circuit and the heating control method. According to the refrigeration equipment and the heating control circuit and the heating control method thereof, the heating of the compressor can be controlled, and the heating efficiency is high.

Description

technical field [0001] The invention relates to a refrigeration device, in particular to a refrigeration device with a heating control circuit for controlling heating of a compressor and a heating control method. Background technique [0002] When the air conditioner is on standby at a low temperature, in order to prevent the lubricating oil and refrigerant inside the air conditioner compressor from freezing, it is usually necessary to heat the compressor. The existing compressor heating technology is to use a relay to control the electric heating belt attached to the outer surface of the compressor to heat the compressor shell, and then heat the lubricating oil and refrigerant inside the compressor from the outside to the inside through heat transfer. [0003] However, when heating with an electric heating tape attached to the outer surface of the compressor, a large part of the heat generated by the electric heating tape will be absorbed by the external environment, causin...
