MECHANICAL HEAT PUMP

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 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. It is suitable for all course levels, from vocational to undergraduate. Learn about MECHANICAL HEAT PUMP price for optimal educational outcomes.. The low-grade heat source is air from the atmosphere. Heat delivered by the unit is in the form of water at up to 55°C, depending upon the source (air) temperature. Learn about MECHANICAL HEAT PUMP for educational labs for optimal educational outcomes.. The work input is in the form of electrical energy supplied to a hermetically sealed compressor. This unit also incorporates internal coupling points and adapters that allow installation of an optional Computerised Data Acquisition Upgrade.
