Title: Takeharu Asaoka: Innovator in Refrigeration Technology
Introduction
Takeharu Asaoka is a notable inventor based in Toyota, Japan. He has made significant contributions to the field of refrigeration technology, holding a total of 3 patents. His innovative designs focus on improving the efficiency and performance of refrigeration systems.
Latest Patents
One of Asaoka's latest patents is an ejector cycle that features a nozzle for decompressing refrigerant. This design includes a receiver for storing refrigerant, which is positioned at the refrigerant outlet side of a condenser. The system incorporates a bypass passage and a switching valve that allows high-temperature refrigerant discharged from a compressor to be introduced into an evaporator while bypassing the condenser during defrosting operations. When the defrosting operation is activated, the switching valve opens, and a fan blows cool air to the condenser. This process enables a portion of the refrigerant discharged from the compressor to flow into the evaporator, effectively removing frost from its surface.
Another patent by Asaoka involves an ejector cycle that enhances circulation performance within the evaporator. In this design, the refrigerant outlet is located above the refrigerant inlet, which improves the flow of refrigerant. This innovation ensures that even with a reduced pumping capacity generated in the ejector, a sufficient amount of refrigerant can still be drawn into the ejector from the evaporator. Additionally, a control unit regulates the amount of cooling air supplied to the condenser based on the temperature of the cooling air, optimizing the refrigerant state introduced to the nozzle. This results in an increased pressure in the ejector and improved power consumption in the compressor.
