Abstract

The invention discloses a control method for a refrigerating system of a high-low-temperature box. The control method for the refrigerating system of the high-low-temperature box comprises the steps that the internal temperature of the high-low-temperature box and the back temperature of an air return pipe of a compressor are detected through sensors, and current temperature differences between current temperatures and corresponding preset temperatures of the two components are calculated; a control method for electromagnetic valves of all the components is determined according to the relationship between the current temperature differences and corresponding preset temperature differences; and the on-state of the electromagnetic valves of the corresponding components in the refrigerating system is controlled according to the electromagnetic valve control method. According to the control method for the refrigerating system of the high-low-temperature box, part of the electromagnetic valves in the refrigerating system are controlled by detecting the temperatures of relevant components, so that the temperature of the high-low-temperature box is rapidly and effectively adjusted.

Description

technical field [0001] The invention relates to the technical field of high and low temperature boxes, in particular to a control method for a refrigeration system of a high and low temperature box. Background technique [0002] When working in the high and low temperature test chamber, the refrigeration system will control the dynamic balance between the cooling process and the constant temperature process according to the settings of the high and low temperature test chamber. In the current high and low temperature test chambers, in order to achieve the cooling effect and avoid temperature fluctuations, the refrigeration system often needs to output excessive cooling capacity, but this will lead to too low temperature, so it is necessary to balance the surplus by heating with electric heating tubes. Cooling capacity. However, the heating of the electric heating tube will cause additional power consumption, which will greatly increase the power consumption of the whole mac...
