Heat pump From Wikipedia‚ the free encyclopedia Jump to: navigation‚ search For theoretical background‚ see Heat pump and refrigeration cycle. Outdoor components of a residential air-source heat pump A heat pump is a machine or device that transfers thermal energy from one location‚ called the "source‚" which is at a lower temperature‚ to another location called the "sink" or "heat sink"‚ which is at a higher temperature. Thus‚ heat pumps moves thermal energy opposite to the direction that

Through common practise of Centrifugal pump operating characteristics is it possible to determine the optimum conditions of particular conditions. The results of typical characteristics are expressed on this work in terms of pump discharge pressure‚ pump efficiency‚ and power demand at various pump speeds of verses pump discharge.
