The energy-saving design practices for direct cooling refrigerator

The area of evaporator on cold storage chamber was added under a constant total evaporator area. Composite and stereoscopic structure with laminated exchanger flake was used on evaporator of freezing chamber. Wing - flakes were fixed outside the refrigerant pipe coil with a S-type to increase the refrigeration capacity of the top part and the bottom part of freezing chamber. The refrigeration cycle of double path was adopted on project study. By the optimizing design of the condenser structure and circling - gas exchanger, direction and position of anti - condensation pipe and evaporator pipe, by matching the load of compressor, condenser and evaporator, a new type of direct cooling refrigerator was recently developed. It consumes 0.39 kWh per day under the maximum load.
