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
