Refrigerating system for refrigerating device

Abstract

The invention discloses a refrigerating system for a refrigerating device. The refrigerating system comprises a compressor, an evaporator and a temperature controller, wherein the temperature controller comprises a temperature sensing bag, an evaporator temperature sensing tube which is arranged on the evaporator, is used for sensing the temperature of the evaporator and is connected with the temperature sensing bag, an outer temperature sensing tube which is used for sensing the temperature in the outer environment of the refrigerating device and is connected with the temperature sensing bag, and a contact sheet, the temperature sensing bag and the contact sheet are connected, and the contact sheet is driven by the temperature sensing bag through the expansion and the contraction to switch on or off the compressor power supply loop of the compressor. According to the refrigerating system for the refrigerating device, control buttons and manual adjustment are not required, temperature control of a refrigerator is completely automatic, the compensation action is played to the changes of environment temperature through the arrangement of the outer temperature sensing tube, the accurate temperature control of the temperature in the refrigerator can be realized, and temperature deviation caused by the manual adjustment is avoided.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a refrigeration system for refrigeration equipment. Background technique [0002] At present, there are two types of temperature control in the refrigerator: mechanical temperature control and electronic temperature control. The electronic temperature control is automatic control with high control accuracy, but the system is complex and the reliability is low; the mechanical temperature control is manual adjustment control with simple structure and high reliability. High, but the control accuracy is low. Electronic temperature control is commonly used in high-end air-cooled refrigerators, while mechanical temperature control is mostly used in ordinary direct-cooling refrigerators. [0003] Generally, when the refrigerator leaves the factory, the temperature control knob is set to the mid-range (MID), and the ambient temperature is about 25°C. When using the refrigerator, ...

Problems solved by technology

However, when the knob is manually adjusted, the adjustment range is often too large or too small, causing the temperature in the refrigerator to be too high or too low; and when the ambient temperature changes and the user forgets to adjust the knob, the temperature in the refrigerator will also be too high or low
