Product Description

Ours is a pioneering organization of this domain which engaged in manufacturing and supplying Refrigeration Trainer. Owing to its accurate design, it is widely used in various colleges, universities and other academic institutions for teaching functionality, structure and basic concepts of a refrigeration system. We offer this apparatus at competitive prices in order to suit the varying demands of our clients. Offered Refrigeration Trainer is widely acknowledged for its high efficiency, longer service life and outstanding performance.

Test Rigs enables the students to study and interpret Vapor Compression Cycle, its factors, working and principle. All the components are affixed on rigid steel framing. The trainer incorporates the tightly sealed compressors; filters / driers, forced convection air-cooled condensers, flow meters, expansion devices and shells and coil type evaporators. Abstracted pressure gauges are given to record pressure level, discharge pressures and digital temperature indicants for assorted temperatures.
The refrigerants utilized are environment friendly.

The calorimeter feature insulated stainless steel tanks. The evaporator conduits are fabricated with refrigerated grade tempered copper tubes. These are the is a direct expansion types evaporators. The heat engrossed by the refrigerants is counterbalanced by heater input. The heater is sinking type resistive water heaters. The calorimeter temperatures can be set with the assistance of digital thermostats. Capable safety devices such as heating thermostats, HP/LP cut-out, and overload protection for mechanical devices are attached for the prevention of any malfunctioning of the system.
The Refrigeration Test Rigs work on vapor compression cycles. The cooling is completed by endlessly circulating, condensing and evaporating a fast supply of refrigerant in a blocked system. Evaporation happens at a low pressure and low temperature while condensation happens at high pressure and temperatures. Thus it is manageable to transfer heat from an orbit of low temperature to a sphere of high temperature.
The compressors drive the low-pressure refrigerants from the evaporator through the accumulators, increases its pressure, and discharges the high-pressure gas to the condensers. The accumulators precludes liquid refrigerant entering the compressor. In the capacitor, the refrigerant rejects its heat to the surroundings by putting air over it. At that particular pressure, the refrigerant keeps its inactive heat and liquidizes. Then the refrigerant move through the drier/filter where any residuary moisture or foreign molecules present, these are stoppered. The flowing of refrigerant into the evaporators is managed by expansion devices where its pressure level and accordingly temperature is raised to the saturation temperature at the related pressure. The low temperature refrigerant get into the evaporator where it assimilates heat from the surrounding medium and gets evaporated. The compressor suctions the cold vapors and the cycle get repeated.
The needed instrumentation is given to measure the different parameters at assorted points. This includes temperature indicators, energy-meters, pressure gauges and controllers, heaters for utilizing load and flow meter to compute the refrigerant flow.

Operating Procedures:

Put the machine in the comely position where its level is crosswise and it is well vented. The machines must have at least 1.5 meters intervals from all laterals.

  • Give 50Hz, 230 volts and 1 phase supply to the unit.
  • Inbound cable should be of capable size (at least 4 sq. mm) to prevent the overheating of it.
  • The electrical points feature MCB of 16 Amps rating.
  • Insure proper earthing.
  • Water tanks should be cleaned with water.
  • Start the operating compressor by swing the switch ON.
  • Switch on the heater that will start mechanically at set point.
  • Control the water flowing to heat exchanger approximately 3 LPM.
  • Record all the readings as per the measuring table.
  • Calculate the outcomes as per the activity remarked at assorted points.
