REFRIGERATION AND AIR CONDITIONING LAB
RAC-101 Vapour Compression Test Rig
The trainer examines a refrigeration circuit under an adjustable load. The refrigeration circuit consists of a compressor, a condenser with fan, a thermostatic expansion valve and a coaxial coil heat exchanger as evaporator. A water circuit serves as load, consisting of a tank with a heater and a pump. The temperature in the tank is adjusted at a controller. The purpose of this refrigeration circuit is the production of cold water. The water flows through the jacket of the coaxial coil heat exchanger, transfers heat to the refrigerant and thereby cools down. All relevant measured values are recorded by sensors and displayed on the digital displays
WATER TO WATER HEAT PUMP (CODE:-RAC-104)
Heat pump & the refrigeration machine basically work on one and the same principle and with the same components. Heat pump is a machine, which deliver heat at a temperature suitable for domestic, industrial & commercial purpose. By added work input from the motor or engine it extract heat from low grade sources. In many circumstances heat pumps can make valuable contribution to energy conservation. The majority of heat pump operate on the vapour compression cycle using a refrigerant as the working fluid. Heat pump is fully sealed R-134A refrigerant system using water to water pumping principle the equipment produce realistic results and has low thermal inertia so that unit stabilize very quickly and enables student’s maximum experimentation’s.
ICE PLANT TRAINER (CODE:-RAC-103)
The unit enables the student to study the basic principles of ice plant cycle within a short period. The test rig is designed for the study thermodynamics of vapour compression refrigeration cycle by the way of demonstration & experimentation. It has the facility to measure various parameters for the experimentation & demonstration. Ice cans are kept in liquid tank, which is cooled by the refrigerant evaporator. As convectional ice plant can take 12 to 24hours to complete the cycle, this ice plant is specially designed to demonstrate process of ice information to be complete with in period of 4 hours & hence it is most suitable for laboratory use .
AIR CONDITION TEST RIG (CODE:-RAC-102)
Air condition test rig unit is required to conduct experiments and demonstrate the process of cooling of atmospheric air. The unit will be fitted with all instruments facilities so that temperature, pressure etc. may be measured at different points in the air conditioning system.
REFRIGERATION TEST RIG (CODE:-RAC-101)
The setup demonstrates the student about the basic principal of refrigeration cycle. The test rig is designed for the supply of thermodynamics of vapor compression refrigeration cycle by way of demonstration & experimentation. It has facility to measure various parameters for experimentation.
