Abstract

The invention relates to a hybrid cooling system, a refrigerator and a freezer using the system. The hybrid cooling system includes: a refrigerant circulation type cooling system; a thermoelectric type system which comprising a thermoelectric module having a heat absorption surface and a heat delivery surface; a first blower which is arranged on the heat absorption surface and / or the heat delivery surface of the thermoelectric module; wherein, the thermoelectric module is cooled by the air cooled through the refrigerant circulation type cooling system, the air is circulated through the heat exchange between the first blower and the thermoelectric module. Through mounting the blower on the heat absorption surface of the thermoelectric module, thereby improving the cooling speed of cooling the air which is cooled by the refrigerant circulation type cooling system again by the thermoelectric module, further improving the thermal efficiency of the whole system and obtaining ultralow refrigerant temperature of -30 to -80 DEG C.

Description

technical field [0001] The present invention relates to a hybrid refrigerating system and a refrigerating device such as a refrigerator and a freezer having the hybrid refrigerating system, more particularly, a refrigerant circulation type refrigerating system and a thermoelectric type refrigerating system are used in the hybrid refrigerating system, thereby obtaining Ultra-low temperature cooling effect. Background technique [0002] At present, various refrigeration systems are used in refrigeration devices, which are generally refrigerant cycle refrigeration systems such as compression refrigeration systems and absorption refrigeration systems, and thermoelectric refrigeration systems. [0003] A traditional refrigerant cycle refrigeration system generally adopts a compression refrigeration system, which includes a compressor, a condenser, an expansion device, and an evaporator, which form a refrigeration cycle to perform operations of compressing, condensing, and evapora...
