Principle of Refrigeration System and Electric Circuit Diagram

The compression refrigeration system operates in four steps: compression, condensation, throttling, and vaporization. The compressor turns coolant into high-pressure gas, which condenses into liquid, then throttles through a capillary device before vaporizing in the evaporator, absorbing heat. The cycle repeats.

Circuit Diagram

Diagram shows the refrigeration cycle components: evaporator, capillary device, drying filter, condenser, and compressor, along with the electrical circuit diagram for the compressor, starter, capacitor, and probes.

Major Parameters

Note: Final specifications are on the product nameplate. Designs may be improved without notice. Damaged supply cords must be replaced by qualified professionals.

WARNING: The freezer uses R290, a flammable refrigerant. Take precautions against fire.

Disposal Instructions

Do not dispose of electrical appliances as unsorted municipal waste. Use separate collection facilities. Contact local government for collection systems. Improper disposal can release hazardous substances into the environment. Check with retailers for haul-away/recycling programs and local regulations.
