Product number: R560

A heat pump is a machine whose prime function is to absorb heat from a low grade source, and to deliver heat at a useful temperature, e.g. suitable for space heating or domestic hot water.

The R560 Hilton Water to Water Heat Pump 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 and having an electrically driven compressor.

The low grade heat source is water. This may be obtained from the local water supply or alternatively the Optional Hilton RE590 Ground Source Simulator is available. This provides 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. The work input is in the form of electrical energy supplied to a hermetically sealed compressor.
