Embodiment Construction
[0021] In order to make the object, technical solution and advantages of the present invention clearer, the method for controlling the start and stop of the refrigeration compressor of the present invention will be further described in detail through the following embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0022] At present, the minimum running time of compressors in the refrigeration industry is generally limited to 6 minutes, and the minimum downtime is 3 minutes. For condensing units used in cold storage, if the target storage temperature is reached, even if the compressor does not run for 6 minutes, it must be forced to run for 6 minutes until the unit has a low-voltage protection shutdown. The compressor control method of starting 6 stopping 3 above is not suitable for condensing units. If the user ...

The invention provides a start and stop control method of a refrigeration compressor. The control method comprises the steps that S1, Ton is set as the shortest operation time of the refrigeration compressor, and Toff is set as the shortest stop time of the refrigeration compressor; S2, timing is started when the refrigeration compressor is started, the time from operation to stop of the refrigeration compressor is recorded as t; and S3, when t is smaller than Ton, the refrigeration compressor can be started again only if the stop time meets Toff, and when the situation that the operation time t is smaller than Ton occurs n times within an hour, the compressor is locked and started again after being stopped for to, wherein n is equal to or larger than one and equal to or smaller than ten, to is from half an hour to two hours. By adoption of the control method, the phenomenon that the compressor is started too many times within an hour can be avoided, reliable operation of the compressor is ensured, and the service life of the compressor is prolonged.
Description
technical field [0001] The invention relates to a compressor control method, in particular to a refrigeration compressor start-stop control method. Background technique [0002] At present, the minimum running time of compressors in the refrigeration industry is generally limited to 6 minutes, and the shortest stop time is 3 minutes. For condensing units used in cold storage, if the target storage temperature is reached, even if the compressor does not run for 6 minutes, it must be forced to run for 6 minutes until the unit has a low-voltage protection shutdown. The compressor control method of starting 6 stopping 3 above is not suitable for condensing units. If the user chooses too large a model, the unit may be under low pressure protection within 6 minutes, and it will be turned on again 3 minutes after the protection, and the compressor will start and stop frequently. short. Contents of the invention [0003] Based on this, it is necessary to provide a compressor co...
