The device in an air conditioner or heat pump through which the refrigerant is circulated and releases heat to the surroundings when a fan blows outside air over the coils. This will return the hot vapor that entered the coil into a hot liquid upon exiting the coil.
Tubing made of either copper or aluminum situated in the condenser or outdoor unit. Hot refrigerant gas is pumped through these coils from the condenser; the heat from the gas is dispersed by circulating air over the coils. The heat transfers from refrigerant to air and is released outside. This heat dissipation converts the refrigerant from a gas into a liquid. Go to the ‘ How air conditioners work' page to learn more.
Part of the outdoor portion of a heating or cooling system, that releases or collects heat from the outside air.
