Industrial Ammonia Refrigeration Systems | AFO-USA.comAmmonia as a Refrigerant Each part of a refrigerator is designed to change the state of the gas in some way. By changing the state of the gas, the system also changes its temperature and how much heat it carries. The compressor, for instance, makes the gas hot and raises its pressure, enabling it to hold larger amounts of heat.

CENTRIFUGAL COMPRESSOR APPLICATIONS—UPSTREAM AND MIDSTREAMdesign parameters [i.e., gas composition, suction temperature and pressure, discharge pressure], whereas the definition of the polytropic head requires the additional knowledge of the compressor efficiency or the discharge temperature.

Supercharger - WikipediaThe rise in temperature is due to its rise in pressure. Energy is being added to the air and this is seen in both its energy, internal to the molecules (temperature) and of the air in static pressure, as well as the velocity of the gas. Inter-cooling makes no change in the density of the air after it has been compressed.
