Water-Water Heat Pump Test Rig

Water-Water Heat Pump Test Rig

Range Of Experiments

• To observe the working principal of heat pump cycle.
• To determine Actual cooling C.O.P, Carnot C.O.P., Theoretical C.O.P.,
• Actual heating C.O.P., Relative C.O.P., Ton of Refrigeration Etc.
• To determine the efficiency of the heat pump system.
• Observe the working of refrigeration cycle also.

Experimental Setup :

• Compressor : ½ Tone, Hermetically sealed compressor, Make Emmelsion – Coplend/equivalent.
• Condenser : Coiled Tube Heat Exchanger acts as a condenser. Copper coil is merged in water tank to cool down the gas temp. Continuous water flow circulation is required to extract the heat of gases.
• Expansion device : Thermostatic expansion valve.
• Evaporator coil : Coiled Tube Heat Exchanger copper coil is merged in water tank to extract the heat from water tank. Same can be mentioned by electric heater.
• Electric Heater : For Balancing refrigerating effect produced.
• Rotameter : For measuring liquid flow of Refrigerant (Eureka Make ).
• Energy Meter : One each for power measurement of compressor & heater.
• Pressure Gauge : 2 Nos. for H.P., L.P. measurement
• HP/LP cutout : 1 No. to suit compressor, Ranko/Equiv.
• Service valve needle type : 1 No.
• Thermostat : 1 No.
• Suitable filter/drier Make Indfoss.

Control Panel :

• 12 Channel Digital Temperature Indicator
• Dimmerstat : 230 V. AC single phase for heating control
• Main On/Off Switch.
• Voltmeter : 0 - 250 V.
• Ammeter : 0 - 15 A.
