Latest Patents

One of Nakano's latest patents is a refrigeration cycle apparatus. This apparatus includes a refrigeration cycle circuit, a liquid receiver, a first valve, and a second valve. The refrigeration cycle circuit consists of a compressor, an outdoor heat exchanger, and an indoor heat exchanger. The liquid receiver is strategically placed in a section of the refrigeration cycle circuit that does not extend through the compressor. The first valve, which can be a solenoid or motor valve, is located in a section that connects the outdoor and indoor heat exchangers through the compressor. The second valve, positioned between the liquid receiver and the indoor heat exchanger, can be an electronic expansion valve, solenoid valve, or motor valve.

Another notable patent is related to air conditioner and expansion valve control. This air conditioner allows refrigerant to circulate through its components, including a compressor, a first heat exchanger, a first expansion valve, a second heat exchanger, and a controller. The controller adjusts the opening degree of the first expansion valve based on the temperature difference between the target temperature and the refrigerant's temperature discharged by the compressor. This innovative control mechanism enhances the efficiency of the air conditioning system.
