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
