Water Chilling Plant Test Rig

This unit consists of a hermetically sealed compressor with air cooled condenser. A capillary or expansion valves are next to condensers following by medium temperature evaporators. Evaporator is surrounded to water tank. Electrical energy supplied to compressor can be measured by energy meter. This apparatus is used to perform the following experiments:
 To study the water chilling plant.
 To determine COP of unit.

 Compressor : 1/2 ton (2612)
 Air cooled condenser : Suitable for above compressor with suitable cooling fan.
 Expansion device: Capillary tube.
 Evaporator coil: Suitable for above compressor surrounded to water tank.
 Water Tank: Water tank surrounded by evaporator having inlet and outlet of water. A agitator motor is fitted to agitate the water.
 Refrigerant : Freon-12
 Energy meter : For power measurement of compressor
 Pressure gauges: 2 Nos. for high pressure for low pressure.
 Digital Temperature Indicator 5 channel.
 Temperature sensor (Thermocouple) - 5 Nos.
 Service valve : 3 Nos. Needle type (Indfos make)
 Ammeter : 1 No.
 Voltmeter : 1 No.
 Thermostat : 1 No.
 Filter/Drier : 1 No.

The equipment is mounted on a sturdy frame with control panel.
