Latest Patents
One of Iijima's latest inventions is a temperature control apparatus designed for automobile air-conditioning systems. This innovative system incorporates a temperature setting device to establish a desired compartment temperature, along with a temperature sensing device that monitors the actual temperature inside the vehicle. The apparatus generates a difference signal based on the discrepancy between these temperatures and utilizes an air flow control device to adjust the blower's air flow rate accordingly. Notably, the system maintains a predetermined air flow rate when the temperature difference exceeds a specified threshold, thereby improving comfort while optimizing performance.
His second patent details an advanced evaporator design that plays a crucial role in the air conditioning process. This evaporator features a side plate with several openings that securely house U-shaped refrigerant tubes. The design includes a cover plate with recesses to create interconnecting bend sections for refrigerant flow. This configuration allows for effective distribution and collection of refrigerant, ensuring efficient cooling within the vehicle. The flow dynamics enable the refrigerant to transition into a gaseous state, which is then collected and directed to complete the cooling cycle.
