WebThis window air conditioner is a typical example of a machine in which two very efficient heat exchangers are used. Air conditioners exploit the feature of phase conversion. When a liquid converts from a liquid phase to a gas phase, it absorbs a tremendous amount of heat. When the refrigerant evaporates, it takes heat from the room it cools. WebAir conditioner and heat pump follow the similar law of thermodynamics. The air conditioner removes heat from the room and maintains it at a lower temperature by throwing the absorbed heat into the atmosphere. The heat pump absorbs heat from the atmosphere and Web20 jul. 2024 · The Second Law: Heat cannot, of itself, pass from a colder to a hotter body. or It is impossible for any system to operate in a thermodynamic cycle and deliver a net … pinball outlet
