Latest Patents

One of his latest patents is for a refrigerant circuit with a passageway control mechanism. This innovative design includes a compressor, a condenser, and an evaporator connected in series. The passageway control mechanism is strategically placed between the outlet side of the evaporator and the inlet side of the compressor. It operates by adjusting the size of the opening area of the passageway in response to the pressure difference between high and low pressure areas within the compressor.

Another significant patent is for an automatic expansion valve for a refrigeration circuit. This invention pertains to an automotive air conditioning system that includes a compressor, a condenser, an expansion valve, an evaporator, and an accumulator arranged serially. The system features a fan that controls the air flow volume of the evaporator based on the operation of a transfer switch. The expansion valve is equipped with two orifices and an actuator that opens and closes one orifice, with the actuator being electrically controlled in response to the transfer switch's operation. This design allows for the use of a smaller accumulator volume while maintaining a simple expansion valve construction.
