Latest Patents
One of Nagai's latest patents is for a vehicle air-conditioning system that incorporates multiple heat-enhancing means. This system utilizes a hot gas heater cycle to heat air blown into the passenger compartment by directly introducing discharged gas refrigerant from a compressor into an interior heat exchanger. Additionally, an electric heater serves as another means of enhancing passenger compartment heating. This dual approach allows for optimal temperature control, ensuring that the driver does not experience adverse effects from fluctuating compartment temperatures. Furthermore, the system effectively manages vehicle window fogging associated with the operation of the hot gas heater cycle.
Another notable patent by Nagai involves a vehicle air conditioner that features a refrigerant cycle system capable of switching between a cooling refrigerant cycle and a hot gas heater cycle. This innovative design includes a mechanism to determine the quantity of retained water in the interior heat exchanger during heating mode. By intermittently controlling the operation of the compressor, the system ensures that the temperature of air blown from the interior heat exchanger remains lower than that of the vehicle windshield, thereby enhancing safety and comfort.
