WATER TO WATER HEAT PUMP Deluxe

A heat pump is a machine whose prime function is to absorb heat from a low-grade source and deliver it at a useful temperature — for example, suitable for space heating or domestic hot water. This unit has been designed specifically to allow students to obtain an overall understanding and appreciation of the performance and characteristics of a heat pump working on the vapour compression cycle with an electrically driven compressor. The low-grade heat source is water, which may be obtained from the local water supply. Learn about WATER TO WATER HEAT PUMP refrigeration India for optimal educational outcomes.. Alternatively, an optional Ground Source Simulator is available, providing a recirculated glycol/water source with a large container that may be filled with locally sourced soil, sand, or water to simulate a static heat source. Heat delivered by the unit is in the form of water at up to 55°C, depending upon the water source temperature. Learn about WATER TO WATER HEAT PUMP specifications for optimal educational outcomes.. The work input is in the form of electrical energy supplied to a hermetically sealed compressor.
