Problems solved by technology
[0003] 1. There is a crankshaft heating belt around the compressor, because the heating heat needs to go through a thick outer wall of the compressor to be transmitted to the oil layer inside the compressor, so the heating efficiency will be greatly reduced and the power consumption will be large;
[0004] 2. The control method of using the heating belt of the crankshaft is: when the compressor is turned off, the heating belt of the crankshaft is turned on; when the compressor is turned on, the heating belt of the crankshaft is turned off. If the temperature exceeds 10°C, there is no need for external heating. If the crankshaft heating belt is at an ambient temperature exceeding 10°C, it will also be turned on when the compressor is stopped at a constant temperature, which will cause energy waste.

Embodiment Construction
[0036] refer to figure 1 , the present invention a kind of compressor coil heating control method, comprises the following steps:
[0037] When it is detected that the compressor is turned off, the heating control of the compressor coil is carried out according to the coil heating condition;
[0038] When it is detected that the compressor is turned on, the heating of the compressor by the compressor coil is turned off by stopping the power supply to the compressor coil.
[0039] refer to figure 2 , further as a preferred embodiment, the heating control of the compressor coil is performed according to the coil heating conditions, which specifically includes:
[0040] Detect the current ambient temperature, real-time coil temperature and compressor oil temperature;
[0041] According to the current ambient temperature, real-time coil temperature and compressor oil temperature, it is judged whether the coil heating conditions are met. If so, the compressor coil is supplied w...

The invention discloses a compressor coil heating control method and a system. The method comprises the following steps: when a compressor is closed, the heating control of a compressor coil is performed according to coil heating conditions; and when the compressor is opened, the power supply to the compressor coil is stopped to close the compressor coil to heat the compressor. The system comprises a compressor closing state control unit and a compressor opening state control unit. The method and the system use the compressor coil in the compressor for heating an oil layer in the compressor, directly perform the internal heating to totally convert heat, improve the heating efficiency, and reduce the power consumption. The method and the system performs the heating control for the compressor coil through the set coil heating conditions, improve the control accuracy, prevent the energy waste caused by heating the compressor under the condition of not needing heating, and largely reduce the energy consumption. The method and the system can be widely applied to compressor protection.
Description
technical field [0001] The invention relates to the technical field of compressor protection, in particular to a compressor coil heating control method and system. Background technique [0002] In a heat pump system, in order to prevent the compressor from being unable to start or liquid hammer in a low-temperature environment, it is usually realized by surrounding the compressor with a crankshaft heating belt, although adding a crankshaft heating belt ensures the safety and stability of the compressor in a low-temperature environment Running, but it has the following problems in heating efficiency and control method: [0003] 1. There is a crankshaft heating belt around the compressor, because the heating heat needs to go through a thick outer wall of the compressor to be transmitted to the oil layer inside the compressor, so the heating efficiency will be greatly reduced and the power consumption will be large; [0004] 2. The control method of using the heating belt of t...
