The open throttling refrigeration device comprises a refrigerant storage bottle, a double-pipe heat exchanger, a filter, a solenoid valve, a temperature controller, a capillary tube, a first-level heat exchanger, a constant pressure valve, a second-level heat exchanger, a third-level heat exchanger and an injection pipe. The refrigerant storage bottle, a refrigerant control valve and a thermal fluid pipe inlet end of the double-pipe heat exchanger are connected through pipelines in turn; a thermal fluid pipe outlet end of the double-pipe heat exchanger, the filter, the solenoid valve, the capillary tube, the first-level heat exchanger, the constant pressure valve, the second-level heat exchanger and a cold fluid pipe inlet end of the double-pipe heat exchanger are connected through pipelines in turn; the cold fluid pipe inlet end of the double-pipe heat exchanger, the third-level heat exchanger and the injection pipe are connected through pipelines; a high-voltage pressure gage is arranged between the refrigerant control valve and the pipeline of the double-pipe heat exchanger; and the temperature controller is connected with the solenoid valve through a data line. The open throttling refrigeration device has the characteristics of convenient installation and maintenance, low power consumption, high efficiency, and capacity of meeting different temperature demands.
Description
technical field [0001] The invention relates to an open throttling refrigeration device, which belongs to the field of refrigeration. Background technique [0002] Although mechanical refrigeration has been widely used, the method of directly using refrigerant evaporation to generate cooling capacity is still used in some special occasions. Such as transportation refrigeration systems, air conditioning systems in emergency shelters, etc. [0003] This type of refrigeration system generally consists of a refrigerant storage bottle 101, a temperature controller 102, a solenoid valve 103, an evaporator 104, and the like. Specifically, the refrigeration process of the truck refrigeration system is as follows: figure 1 shown. [0004] There are many refrigeration methods for truck refrigeration systems, one of which is to use liquid nitrogen or liquid carbon dioxide to freeze and refrigerate goods. Its main components are refrigerant storage tank, control solenoid valve, temp...
