Abstract

The invention discloses a refrigerator temperature control system which comprises a compressor. The refrigerator temperature control system is characterized by further comprising a temperature sensor, a PLC (programmable logic controller), a refrigerant and a touch display for human-computer interaction, the PLC outputs control signals to the compressor by controlling temperature of a refrigerator, the refrigerant realizes refrigerating by being liquefied and then gasified through the compressor, the display is connected with one communication port of the PLC to monitor and input temperature data, and the temperature sensor is connected with another communication port of the PLC to collect temperature and transmit the same to the PLC for processing. The refrigerator temperature control system is simple to operate; the PLC is used in the control system, so that when the refrigerator is in a failure, the display can display errors, the refrigerator can be maintained timely, and the refrigerator temperature control system has a detection function.

Description

technical field [0001] The invention relates to a temperature control system, in particular to a refrigerator temperature control system. Background technique [0002] At present, with the continuous progress of society, the refrigerator has become one of the most widely used electrical appliances, and it has also become a must for every family. Due to the fresh-keeping function of the refrigerator, the food is not easy to spoil and deteriorate, avoiding a lot of unnecessary waste . [0003] The temperature of the refrigerator is set during work, but if the refrigerator breaks down and stops working, the problem cannot be found in time. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a refrigerator temperature control system with detection function. [0005] In order to solve the above-mentioned technical problems, the present invention provides a refrigerator temperature control system, which includes a compre...
