Latest Patents

One of Takahiko Ao's latest patents is an "Air conditioner and refrigerant heater outlet temperature control method." This innovative air conditioning system includes an outdoor unit and at least one indoor unit connected to each other. The outdoor unit features a variable capacity compressor, a four-way valve, an outdoor heat exchanger, and a refrigerant heater, while the indoor unit contains an indoor heat exchanger. A saturation temperature calculator computes the saturation temperature at the refrigerant heater outlet pressure. Additionally, a refrigerant heater outlet temperature detection circuit detects the refrigerant temperature near the refrigerant heater outlet. A superheating calculator calculates refrigerant superheating at the refrigerant heater outlet based on values supplied from the detection circuit and saturation temperature calculator. A compressor frequency control circuit then adjusts the compressor frequency to maintain the calculated refrigerant superheating at a specific level.

Another significant patent is for a "Multi-room air conditioning system." This system includes an outdoor unit and multiple indoor units connected in parallel to the outdoor unit. A compressor frequency and combustion control calculator reads the load level for each indoor unit from a load coefficient table using a differential temperature calculated by a differential temperature calculator and a rated capacity stored in a rated capacity memory. The calculator multiplies the sum of the load levels by a predetermined constant and adds a compensation value to obtain a frequency value, which is used to control the compressor. Furthermore, the calculator sets a target combustion level using the frequency value for controlling a refrigerant heater mounted in the outdoor unit.
