Title: Yuji Ohba: Innovator in Air Conditioning Technology
Introduction
Yuji Ohba is a prominent inventor based in Kawasaki, Japan. He has made significant contributions to the field of air conditioning technology, holding a total of 10 patents. His innovative designs focus on improving the efficiency and effectiveness of air conditioning systems.
Latest Patents
One of Yuji Ohba's latest patents is an advanced air conditioning system. This system is designed to suck air exhausted from an information processor and cool it down before exhausting the cooled air. The air conditioner is capable of acquiring a cooling state and determining whether its cooling capacity exceeds an upper limit value. If it does, the system reduces the volume of exhaust air accordingly. The air conditioner calculates a thermal load based on the volume of exhaust air and the temperature difference between the exhaust and suction air. It can also measure the temperature of the exhaust air to ensure optimal cooling performance.
Another notable patent is the air conditioning control apparatus and method. This apparatus controls an air conditioner in a room that houses a computer. It repetitively obtains detected values of total power consumption for both the computer and the air conditioner, as well as the air temperature at the air inlet. The system stores these values in memory and determines an approximate expression representing the relationship between total power consumption and air temperature. By using this expression, it calculates the air temperature that corresponds to the lowest total power consumption and adjusts the air conditioner accordingly.
