The hermetically sealed refrigerant compressor incorporates a brushless three phase DC electric motor that is driven by a variable speed controller. Compressor speed and power supplied is displayed on the PC.
The condenser and evaporator are brazed plate heat exchanger and utilize a large common reservoir of water to minimize changes in water temperature during operation. The refrigerant exiting the compressor passes through a condenser, receiver, filter, variable area flow meter, expansion valve and evaporator before retuning to the inlet side of the compressor.
The refrigeration circuitry includes a water cooled condenser complete with isolating valves, manual expansion valve, evaporator, variable area flowmeter for mass flow of refrigerant, filter/drier unit, sight glass and over pressure cut-out for unit protection. The unit is designed to use Tetrafluoroethane as the refrigerant with a twin cylinder reciprocating compressor, belt driven by the variable speed dynamometer.
The evaporator coil is mounted in an electrically stirred water/glycol mixture contained in a thermally insulated, stainless steel tank. The water/ glycol mixture is protected from over temperature conditions by a thermostat should the heater should be left on when the compressor is not circulating refrigerant. Heating of this water/glycol mix is infinitely variable enabling balanced experimental conditions over a wide range of temperatures to be obtained.
Experimental Capabilities:
Determine the Mechanical, Thermodynamic (Isentropic) and Volumetric efficiencies.
Estimate the rate at which heat is transferred to the system from the surrounding environment.
Determine the energy flows and coefficient of performance for given operating instructions.
Operate the refrigeration unit over a range of conditions.
Estimate the Heat Transfer Coefficient.
Compile an energy balance under light load and full load conditions.
Examine the behaviour refrigerating cycle under variable loads and speeds.
