The increase in Pressure and Temperature

P-H chart shows us, at first glance, changes of pressure, the saturation temperature and enthalpy of the refrigerant as it passes through each of the four components. Here we see that the compressor accept low pressure and low temperature of superheated refrigerant gas, in the point 2, after she disappeared in the evaporator and increases its pressure and the saturation temperature. - It gets rid of the refrigerant, in point 3, as high pressure, high temperature, hot gas, and sends it to the condenser where it condenses back into a liquid.

The pressure and temperature of saturation increased substantially. Its enthalpy also increased. Comfort, air-conditioning compressor using R-22 and the air cooled condenser is usually causes the changes shown in the table.
