Title: Satoshi Ohya: Innovator in Refrigeration Technology

Introduction

Satoshi Ohya is a prominent inventor based in Gunma, Japan, known for his contributions to refrigeration technology. With a total of 4 patents to his name, he has made significant advancements in the field, particularly in the development of efficient refrigerating systems.

Latest Patents

One of his latest patents is a refrigerating apparatus and method of controlling refrigerating. This innovative apparatus is designed to respond accurately and swiftly to transient changes in a refrigerant circuit or accumulated deviations in the degree of superheat of a refrigerant. It effectively prevents the return of liquid refrigerant to the compressor and mitigates overheating issues. The system includes a refrigerant circuit composed of a condenser, an expansion valve, and an evaporator, all connected in series. It features means for detecting the evaporating temperature of the refrigerant and the exit temperature of the evaporator, along with a control mechanism that adjusts the expansion valve based on these temperatures using fuzzy reasoning.

Another notable patent is a defrosting controller for refrigeration systems. This controller calculates the frost melting period by measuring the evaporator temperature during defrosting through an evaporator temperature sensor. It establishes a refrigerating operation rate, which is the ratio of the frost melting process duration to the total open period of an electronic motor-driven valve during refrigeration. This innovation allows for intelligent decision-making regarding whether to skip the next defrosting operation.
