[0002] Refrigeration equipment refers to equipment mainly used for food refrigeration, refrigeration of various types of goods and indoor air conditioning in summer. It is mainly composed of a compressor, expansion valve, evaporator, condenser and accessories, and pipelines. Common refrigeration equipment is mostly a single-circuit system, using a single capillary tube and thermostat, which is difficult to adapt to equipment with both freezing and refrigeration needs. For this reason, a dual-circuit refrigeration refrigeration equipment came into being. It is a dual-circuit system consisting of two capillaries, two thermostats and a two-position three-way solenoid valve. It reasonably solves the diversion of refrigerant to the evaporators of the refrigeration and freezer compartments, and achieves matching between the refrigeration compartment and the freezer compartment.
