Problems solved by technology

When the compression ratio is large or the superheat of the return air is large, such as in low-temperature refrigeration fields such as oil-gas separation, the discharge temperature of the compressor will increase significantly at this time, and the working environment of the compressor will deteriorate sharply. If measures are not taken to control it in time, it may Carbonization of compressor lubricating oil and serious consequences of compressor burnout due to poor lubrication

Abstract

The invention provides an adjustable cooling device for a vehicle-mounted cold storage area. The adjustable cooling device comprises a cabinet, wherein a refrigeration chamber and a cold-hot air exchange chamber are formed in the cabinet; the cold-hot air exchange chamber is provided with an air inlet and an air outlet; air channels are formed in two sides of the cabinet; the upper ends of the airchannels are connected with fans; the air inlet is connected with one air channel; a temperature sensor is arranged in the cabinet; a control device is arranged above the cabinet; a compressor, a condenser, an expansion valve and an evaporator which are connected sequentially by a refrigeration pipe are arranged in the refrigeration chamber, a connecting pipe is arranged on a low-pressure gas pipe between the evaporator and the compressor, a solenoid valve is arranged on the connecting pipe, and the control device is connected with the temperature sensor and the solenoid valve. The cold-hot air exchange chamber is arranged specially, so that cold-hot air exchange is performed in special closed space, and service life is prolonged; temperature difference in the chamber is monitored by thetemperature sensor, so that the temperature in the refrigeration chamber is controlled more precisely, and food protection is safer.

Description

technical field [0001] The invention belongs to the technical field of refrigerating devices, and in particular relates to an adjustable cooling device for a vehicle-mounted refrigerating area. Background technique [0002] At present, various vapor compression refrigeration devices are more and more widely used, and their operating conditions are becoming more and more complicated. When the compression ratio is large or the superheat of the return air is large, such as in low-temperature refrigeration fields such as oil-gas separation, the discharge temperature of the compressor will increase significantly at this time, and the working environment of the compressor will deteriorate sharply. If measures are not taken to control it in time, it may The carbonization of the compressor lubricating oil and the serious consequences of the compressor burning out due to poor lubrication occur. Contents of the invention [0003] In view of this, the present invention aims to propo...
