In engineering, however, the term heat pump is generally reserved for equipment that heats for beneficial purposes, rather than that which removes heat for cooling only. Learn more about ASHRAE Conferences at ashrae.org. Flexible Design. It's also worth noting that ASHRAE provides two different metrics for each equipment class: recommended and allowable. Learn More With more than 50,000 members from over 130+ nations, ASHRAE is a diverse organization dedicated to advancing the arts and sciences of heating, ventilation, air conditioning and refrigeration to serve humanity and promote a sustainable world. An applied heat pump requires competent field engineering for the specific application, in contrast to the use of a manufacturer-designed unitary product. The allowable metric is essentially a broad range within which the equipment can be expected to function properly. Fluid FlowFlowing fluids in HVAC&R systems can transfer heat, mass, and momentum. Invite your colleagues to join the ASHRAE community today. Also called "loose fit, long life," this design principle anticipates and allows for future adaptations needed to extend a building's useful life. This has been an excellent experience, and both instructors have the rare ability to know HVAC and communicate to us. In the past, this was accomplished by drawing a continuous stream of water from a utility water supply or a natural body of water, heating it as it passed through the process, and then discharging the water directly to a sewer or returning it to the body of water.
