摘要： A refrigerator includes a secondary cooling path for circulating liquid coolant through the refrigerator wherein the liquid coolant is cooled by the freezer compartment and wherein the liquid coolant cools the ice maker and the ice bin as the liquid coolant circulates through the secondary cooling path. A pump is positioned along the secondary cooling path for pumping the liquid coolant through the secondary cooling path. A tube having a first end proximate the pump and an opposite end exposed to atmosphere may control suction pressure associated with the pump. The refrigerator reduces frost build up through configuration of the secondary cooling path or performing ice harvesting operations which melt frost. The secondary cooling path may be used to provide for circulating hot liquid. The secondary cooling path may be used to provide for circulating liquid coolant during a power outage.

摘要： A refrigerator is provided that includes a low energy defrost system and method for melting frost formed on an evaporator of a cooling system for the refrigerator. The low energy defrost system includes using air from the refrigerator compartment or external air adjacent the refrigerator to be directed to the evaporator and passed adjacent the evaporator coils to melt any frost formed thereon. As the air is above freezing temperature, it will melt any frost formed on the coils without the need of use an electrical heater. Re-cooled air from the melted frost may then be directed back into the refrigerator compartment to be used to aid in cooling the refrigerator compartment or keeping the refrigerator compartment at the programmed or predetermined temperature.

摘要： Systems and methods for refrigerating crops and other goods and for defrosting a refrigeration system. A refrigerant is circulated between a condenser and a refrigerator to cool air in the refrigerator. Heat is removed from the refrigerant at the condenser. Periodically the cycle of refrigerant and air can be reversed to melt frost in the refrigerator. Frost can be detected by a sensing mechanism and the refrigerant and air cycles can be reversed in response to detecting the frost. The frost can be removed quickly without removing the goods from the refrigerant.

摘要： The present invention discloses a defrost operating method for a refrigerator which performs a defrost operation by controlling operations of a compressor and a fan on the basis of a continuous operation time of the compressor and surface temperatures of evaporators to prevent frost from being formed on the evaporators, when cool air is generated in a freezing chamber and a refrigerating chamber by circulating refrigerants through a refrigeration cycle built in a refrigerator main body and forcibly circulated bX rotating the fan. The defrost operating method for the refrigerator can omit a general defrosting heater by performing the defrost operation by using the compressor and the fan. In addition, the defrost operating method for the refrigerator improves heat exchange efficiency and reduces power consumption by efficiently performing the defrost operation.
