Heat recovery ventilation — (also known as a heat exchanger, air exchanger or air to air exchanger) is a ventilation system that employs a counter flow heat exchanger between the inbound and outbound air flow. HRV provide fresh air and improved climate control, while also… … Wikipedia
Heat transfer — is a discipline of thermal engineering that concerns the exchange of thermal energy from one physical system to another. Heat transfer is classified into various mechanisms, such as heat conduction, convection, thermal radiation, and phase change … Wikipedia
heat pipe — n. a thin, sealed metal tube that efficiently transfers heat without a pump, using a fluid that vaporizes at the hot end, condenses as it reaches the cooler end, and returns to the hot end by capillary action through a wick or along tiny grooves… … Universalium
Heat pump — A heat pump is a machine or device that moves heat from one location (the source ) to another location (the sink or heat sink ), using work. Most heat pump technology moves heat from a low temperature heat source to a higher temperature heat sink … Wikipedia
Heat transfer coefficient — The heat transfer coefficient, in thermodynamics and in mechanical and chemical engineering, is used in calculating the heat transfer, typically by convection or phase change between a fluid and a solid::Delta Q=h cdot A cdot Delta T cdot Delta… … Wikipedia
Heat pump — 1) (air source) An air source heat pump is the most common type of heat pump. The heat pump absorbs heat from the outside air and transfers the heat to the space to be heated in the heating mode. In the cooling mode the heat pump absorbs heat … Energy terms
