Air Conditioning and Global Warming Air conditioning systems use energy to remove heat from a given location‚ transferring it to the exterior in the form of exhaust. Some of the energy is invariably wasted as heat‚ and this additional heat must also be exhausted. Thus‚ air conditioning results in net heat release to the environment. The warming effect is aggravated‚ moreover‚ because higher forms of energy such as electricity are used to power air conditioners. Generating and transmitting this

Air Conditioning and Heat Pump Systems Clinton Ward COM155 February 17‚ 2013 Joyce Keeling Air Conditioning and Heat Pump Systems Air conditioners and heat pump systems are used by most people in the world today. They are used to cool in the summer time and to heat in the winter time. These machines are bought and used when most people do not even understand the principle on which they work. The machines are expected do what they are designed to do‚ and when they cease to do this‚ they can
