The influence of the operating parameters high pressure and suction gas superheat (“internal parameters”) plus the heat source temperature, the heat sink inlet and outlet temperatures and the compressor speed (“external parameters”) on the COP and heating capacity are studied using data from ...
In addition to the working fluid composition, the study also addressed the effect of the mixture's mass fraction, which ranged from nearly pure refrigerant to nearly pure CO2, turbine inlet pressure and the heat source's temperature on the thermal performance of the cycle. The results obtained ...
3. The ultrasonic receiver 30 will produce a voltage that varies with the sound pressure incident upon it, and the resulting signal is applied to a preamplifier/high-pass filter including components 31, 32, 33, and 34. The output of the preamplifier/high-pass filter is then fed through a...

The compression unit (30) displaces the high pressure refrigerant into the interior of the hermetically sealed container (11). Refrigerant R32 (difluoromethane) is used as a refrigerant. The compression unit (30) is driven at a predetermined speed or below its level at the start of the ...
To provide a refrigerant containing HFO-1132(E) which suppresses disproportionation when a pressure of the refrigerant is 3.0 MPa, and a new refrigerant containing HFO-1132(E).SOLUTION: There is provided a method for suppressing a disproportionation reaction of HFO-1132(E) includes a step of ...
