Latest Patents

The available information identifies one patent associated with Ijuin: Refrigeration cycle device. The invention describes a first refrigeration cycle with a compressor, radiator, air-conditioning expansion valve and evaporator, and a first expansion valve and evaporator. Its first refrigerant evaporates in at least one of the two evaporators, absorbing heat either from ventilation air or from outside air.

A second refrigeration cycle includes a compressor, radiator, expansion valve, and evaporator. A heat transfer portion can switch the heat-radiation destination from the first radiator to the second refrigerant in the second evaporator or to outside air. The second radiator transfers heat from the second refrigerant to ventilation air, supporting air conditioning through coordinated heat exchange.
