WATER-WATER HEAT PUMP TEST RIG

/in /by

RANGE OF EXPERIMENTS :

  1. To observe the working principal of heat pump cycle.
  2. 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.
  3. To determine the efficiency of the heat pump system.
  4. Observe the working of refrigeration cycle also.

EXPERIMENTAL SETUP :

  1. Compressor :          ½ Tone, Hermetically sealed compressor, Make

Emmelsion – Coplend/equivalent.

  1. 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.

  1. Expansion device : Thermostatic expansion valve.
  2. 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.

  1. Electric Heater :           For Balancing refrigerating effect produced.
  2. Rotameter  :           For measuring liquid flow of Refrigerant (Eureka Make ).
  3. Energy Meter :           One each for power measurement of

compressor & heater.

  1. Pressure Gauge : 2 Nos. for H.P., L.P. measurement
  2. HP/LP cutout :           1 No. to suit compressor, Ranko/Equiv.
  3. Service valve needle type : 1 No.
  4. Thermostat :           1 No.
  5. Suitable filter/drier Make Indfoss.

CONTROL PANEL : 

  1. 12 Channel Digital Temperature Indicator
  2. Dimmerstat :           230 V. AC single phase for heating control
  3. Main On/Off Switch.
  4. Voltmeter :           0 – 250 V.
  5. Ammeter :           0 – 15 A.

SPACE REQUIRED :           1.5 m. (L) x 1.0 m (W).

WEIGHT                     :           @ 170 Kg

SERVICE REQUIRED: 1. Power Supply : 440 V. A.C., 50 Hz.

Water Supply              :           @ 20 LPM.
