AIR CONDITIONING CYCLE TEST RIG

RANGE OF EXPERIMENTS: 

1. To study all components used in Air Conditioning system.
2. To study the Vapor compression Refrigeration cycle.
3. To study the cooling, humidification,& dehumidification process.
4. To determine the Refrigeration Effect, Work Input, Actual C.O.P., Carnot C.O.P., Theoretical C.O.P., Relative C.O.P., Ton of Refrigeration, and Plant Efficiency.

EXPERIMENTAL SETUP : 

1. Compressor : Hermetically sealed compressor.
2. Condenser : Air Cooled condenser made

out of copper pipe & Aluminum fins of matching

capacity with fan cooling.

3. Evaporator : Air calorimeter type evaporator. The air passed by a fan through duct.

The expanded refrigerant passes through evaporator

coils, fixed in the duct. The passing air comes in contact with the coils & gets cooled.

4. Expansion device : Thermostatic expansion valve.
5. Energy Meter : For power measurement of compressor.
6. Pressure Gauge : 2 Nos. for H.P., L.P. measurement
7. Hand Shut Off type Service valve.
8. Electric Heater : Finned type heater for air heating.
9. Rotameter for Refrigerant flow measurement.
10. Duct : Air duct of size 250 x 250 make out of

CRC sheet in which evaporator is fitted.

11. Baby Boiler : Electrically fired small baby boiler for

maintaining humidity of air with electrical heater

12. Blower : 1 HP capacity centrifugal blower with air

control arrangement.

CONTROL PANEL :

1. 12 Channel Digital Temperature Indicator
2. HP-LP Cutout: Make Ranco /Danfoss or Equivalent.
3. Switches: For compressor, condenser fan,

Dehumidifier Heater, blower & boiler heater.

4. Voltmeter: 0 – 250 V.
5. Ammeter: 0 – 15 A.
