Dimensions and weight

LxWxH: 1630x800x1900mm

Weight: approx. 195kg

Electricity meter: Watt-hour type recording

electrical input to the compressor using a digital wattmeter


designed to allow students to gain a common understanding and assessment of performance and

characteristics of a heat pump operating on a steam compression cycle and with an electric drive

compressor, and is suitable for all levels of the course, from professional education to students.

Atmospheric air is of poor quality


Work is introduced as electrical energy

into a hermetically sealed compressor


Panel: High quality ABS.

Compressor: fully sealed single cylinder

reciprocating type. Engine displacement about 8.85 cm³ revolutions

Condenser: water refrigerant


Fluid receiver: with valves. Contains all refrigerant charge if required.

Evaporator: air to refrigerant


Digital thermometer: resolution 0.1 ° C, with switch on select from six thermocouples

Flow meters x 2: type of variable area – indicate

R134a and H2O costs.

Gauges x 2: to indicate the pressure of R134a to the evaporator and condenser.


Safety Features: – High Pressure Capacitor Switch

and compressor thermal switch. – Residual current switch. – Combined bipolar trunk

circuit breaker and overload disconnected
