Refrigerant throttling device with temperature monitoring function

Abstract

The invention discloses a refrigerant throttling device with a temperature monitoring function. The device comprises a refrigerant throttling device, wherein a refrigeration controller is also arranged on the lower surface of the front side of a valve body of the refrigerant throttling device, a main body of the refrigeration controller is a rectangular fixed support frame, the thin end of the fixed support frame is provided with a screw positioning hole, a screw passes through the screw positioning hole to be fixed on the valve body, a thermistor is arranged in the valve body in a position near the liquid state end connecting opening of an evaporator, and two signal wires connected with the thermistor are respectively led out from a hole arranged at the thick end of the fixed support frame. The refrigerant throttling device provided by the invention solves the problem that the existing refrigerant throttling device cannot realize the direct temperature monitoring, an additional temperature monitoring device is omitted for the refrigeration system, the hardware cost and the use space are saved, the temperature of the refrigerant can be directly monitored in the temperature monitoring position, and the temperature monitoring accuracy is improved.

Description

technical field [0001] The invention relates to a refrigerant throttling control device, in particular to a refrigerant throttling device with a temperature monitoring function. Background technique [0002] In the refrigeration system, the throttling mechanism, the compressor, the condenser, and the evaporator are called the "four major parts" of the refrigeration system. They are one of the essential components in the refrigeration system. Controls the flow rate of the evaporator refrigerant and the superheat of the evaporator outlet. The existing throttling mechanism cannot directly monitor the refrigerant temperature, and an additional temperature monitoring device needs to be added during use to detect the temperature difference between the throttling mechanism and the evaporator, which not only increases the hardware cost but also increases the use of space, and because the refrigeration control The device does not directly test the refrigerant, but tests the temperat...

AI Technical Summary

Problems solved by technology

The existing throttling mechanism cannot directly monitor the refrigerant temperature, and an additional temperature monitoring device needs to be added during use to detect the temperature difference between the throttling mechanism and the evaporator, which not only increases the hardware cost but also increases the use of space, and because the refrigeration control The detector does not directly test the refrigerant, but the temperature of the refrigerant circulation pipe, and the tested temperature is different from the actual refrigerant temperature.
