Electrical Wiring Diagrams for Air Conditioning Systems

A heating, ventilating and air-conditioning (HVAC) system is a simple system of heating and cooling exchangers using water or refrigerant (direct expansion system) as the medium. Pumps move the heated or cooled water to the exchangers. Fans then move the warmed or cooled air created at the exchangers to the occupied building interiors.

Refrigeration - Wikipedia

The term refrigeration means cooling a space, substance or system to lower and/or maintain its temperature below the ambient one (while the removed heat is rejected at a higher temperature). In other words, refrigeration is artificial (human-made) cooling. Energy in the form of heat is removed from a low-temperature reservoir and transferred to a high-temperature reservoir.
