Abstract

The invention discloses a unit type refrigerator. The unit type refrigerator is characterized by mainly comprising a direct current inverter compressor, a four-way reversing valve, a heat exchanger, an oil separator, a liquid accumulator, a filter, sight glass, stop valves, an electronic expansion valve and an air cooling fan, wherein the direct current inverter compressor communicates with the oil separator, the oil separator communicates with the four-way reversing valve, the four-way reversing valve communicates with the heat exchanger, the direct current inverter compressor and the stop valves respectively, the heat exchanger communicates with the liquid accumulator, the liquid accumulator communicates with the filter, the filter communicates with the sight glass and the two stop valves respectively, and the two stop valves are connected with the air cooling fan. Through matching of the electronic expansion valve and the four-way reversing valve, the system operates more stably andmore reliably, and by means of combination with an intelligent controller, the system has higher efficiency during refrigerating.

Description

technical field [0001] The invention relates to a unit refrigerator, which belongs to the technical field of refrigeration engineering. Background technique [0002] A refrigerator is a mechanical device that uses a compressor to change the pressure of a refrigerant gas to achieve low-temperature refrigeration. The compressor used is different from ordinary air compressors because of its different operating conditions and compressed working media. According to the difference in the structure and working principle of the refrigerator, it is similar to the air compressor, and can also be divided into several different forms such as piston type, screw type, and centrifugal type. The freezer is one of the most important components in compression refrigeration equipment. Refrigerators are composed of five parts in series: compressor, condenser, evaporator, dry filter, and expansion throttle valve. The right amount of refrigerant is injected into it, and the electrical appliance...
