Latest Patents
Inaba's latest patents include an air conditioner and a defrosting operation method. The first patent describes a hot gas bypass circuit that connects the discharge side of the compressor to a portion between the heat source side heat exchanger and the expansion valve. This system includes an on-off valve that opens and closes the channel of the hot gas bypass circuit, along with a control device that selects between hot gas bypass defrosting and reverse cycle defrosting based on the frosting amount on the heat source side heat exchanger. The control device ensures that a portion of the refrigerant discharged from the compressor is supplied to the heat source side heat exchanger via the hot gas bypass circuit.
The second patent focuses on an air conditioner with both indoor and outdoor units. In this design, the average refrigerant exit temperature is determined by averaging the temperatures of the refrigerant exits of indoor heat exchangers in multiple indoor units. The system controls the indoor expansion valves to maintain the temperature difference within a predetermined range, enhancing the efficiency of the air-warming operation.
