Refrigeration Cycle Training Equipment R1234yf
This is a device that uses R1234yf, a refrigerant developed as a substitute for HFC-134a. Compared to HFC-134a, it has a lower ozone depletion potential and global warming potential, making it an environmentally friendly refrigerant. The refrigeration system using R1234yf (refrigerant for car air conditioners and vending machines) is clearly arranged on a tabletop base. The high-temperature, high-pressure refrigerant gas (superheated vapor) discharged from the compressor passes through the dryer, solenoid valve, and sight glass, where it is cooled and condensed into a liquid (subcooled liquid) in the condenser. The low-temperature, low-pressure liquid refrigerant (saturated liquid) that passes through the capillary tube (expansion valve) via the sight glass enters the evaporator, where it undergoes heat exchange with air, providing latent heat of vaporization to the air. The vaporized refrigerant (superheated vapor) then returns to the compressor through the sight glass and solenoid valve. A P-h diagram (pressure-enthalpy diagram) is created from the measured pressures and temperatures of each component, and the coefficient of performance (COP) of this device is calculated from the inlet pressure and temperature of the compressor and the compressor efficiency.
