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. So there are two stages to heating and cooling 1. Water stage: water is the most efficient and inexpensive medium that we can cool directly (through a chiller) or heat (through a boiler).

Resistance (R) is defined as the opposition to the flow of electrons and is measured in ... The motor is connected to a high voltage electrical supply of 680V. When this motor is energized, it must draw enough current to ... damages the switch by severely burning the contact points.
