9PRACTICE PROBLEM
The refrigerant used in air-conditioning systems can easily undergo vaporization at atmospheric pressure and compression at higher pressures. The system then acts as a closed system consisting of the refrigerant undergoing these two stages. The vaporization occurs in an expansion chamber at low pressures. The compression of the vapor back to its liquid phase occurs in a compression chamber at high pressure.
