DOMESTIC REFRIGERATOR TRAINER

PRODUCT DESCRIPTION & PRINCIPLE OF OPERATION
This Refrigerator Works on simple Vapour Compression Cycle. Continuously circulating, evaporating, and condensing a fixed supply of refrigerant in a closed system accomplish mechanical refrigeration. Evaporating occurs at a low temperature and low pressure while condensation occurs at a high temperature and pressure. Thus, it is possible to transfer heat from an area of low temperature (i. e. refrigerator cabinet) to an area of high temperature (i.e. kitchen) Beginning the cycle at the evaporator inlet the low pressure liquid expands, absorbs heat, and evaporates, changing to a low pressure gas at the evaporator outlet. The Compressor pumps this gas from the evaporator through the accumulator increases its pressure, and discharges the high pressure gas to the condenser accumulator is designed to protect the compressor by preventing slugs of liquid refrigerant from passing directly into the compressor. An accumulator should be included on all systems subjected to varying load conditions or frequent compressor cycling. In the condenser, heat is removed from the gas which then condenses and becomes a high pressure liquid. In some systems this high-pressure liquid drains from the condenser into the liquid storage or receiver tank. On other systems, both the receiver and the liquid line valve are omitted. A heat exchanger between and the liquid line and the suction line is also an option item which may or may not be includes in a given system design. Between the condenser and the evaporator an expansion device is located. Immediately preceding this device is a liquid line strainer/ drier which prevent plugging of the valve or tube by retaining scale, dirt and moisture. The flow of refrigerant into the evaporator is controlled by the pressure differential across the expansion device or, in the case of a thermal expansion valve, by the degree of superheat of the suction gas. Thus, the thermal expansion valve shown requires a sensor bulb located at the evaporator outlet. In any case, the flow of refrigerant into the evaporator load increase as the evaporator load increases. As the high pressure liquid refrigerant enters the evaporator it is subjected to a much lower pressure due to the suction of the compressor and the pressure drop across the expansion device. Thus the refrigerant tends to expand and evaporate. In order to evaporate the liquid must absorb heat from the air passing over the evaporator.
Eventually the desired air temperature is reached and the thermostat or cold control will break the electrical circuit to the compressor motor and stop the compressor. As the temperature of the air through the evaporator rises, the thermostat or cold control remakes the electrical circuit. The compressor motor and starts, and the cycle continue

REFRGERATION TEST RIG

PRODUCT DESCRIPTION:
The Refrigeration Test Rig works on vapor compression cycle. The refrigeration (i.e. process of maintaining a closed space temperature below ambient temperature) is accomplished by continuously circulating, evaporating and condensing a fixed supply of refrigerant in a closed system. Evaporation occurs at a low temperature and low pressure while condensation occurs at a high temperature and pressure. Thus it is possible to transfer heat from an area of low temperature (in this case calorimeter) to an area of high temperature (the surroundings).
The required instrumentation is provided to measure the various parameters at different points. This includes pressure gauges, temperature indicators and controller, energy-meters, heater for applying load and flow meter to measure the refrigerant flow

VAPOUR ABSORPTION TEST RIG

PRODUCT DESCRIPTION
“Vapour Absorption Refrigerator” earlier known as “Electrolux” refrigerator is a self contained refrigerator working on absorption technology. In the absence of a compressor or pump, the circulation takes place by density difference. The system is pre-charged with three fluids namely water, ammonia and hydrogen. Hydrogen is used as an “inert gas” and does not undergo any phase change and heat transfer processes. Its purpose is to keep the pressure of the system constant. It uses an electrically operated generator, where, the ammonia vapours dissolved in water are separated and pure ammonia vapours enter the condenser. In the condenser, the high pressure vapours reject its latent heat to the surroundings and get liquefied. The liquid ammonia expands through expansion device where its pressure and temperature is reduced and cold low pressure vapour enters the evaporator where it absorbs heat from the space to be cooled and then vaporized ammonia absorbs in water. This strong solution then enters the generator and the cycle repeats.

PRINCIPLE OF OPERATION
Electrolux principle works on 3-fluid system. There is solution circulation pump. Total pressure is the same throughout the system. The third fluid remains mainly in the evaporator thus reducing partial pressure of refrigerant to enable it to evaporate at low pressure and hence low temperature.
The schematic diagram of the Electrolux refrigerator working on NH3-H2O system with H2 as the third fluid is shown in figure. Liquid NH3 evaporates in the evaporator in the pressure of H2.Hydrogen is chosen as it is non –corrosive and insoluble in water.
A thermosyphon bubble pump is used to lift the weak aqua from the generator to the separator. The discharge tube from the evaporator the generator is extended down below the liquid level in the generator. The bubbles rise and carry slugs of weak NH3-H2O solution into the separator.

Two U-bends are provided as vapour- locks to prevent H2 from getting into the high side or solution circuit.

Partial pressure of H2 provides the pressure difference of NH3 between the condenser and evaporator. Accordingly, we have:

In condenser pure NH3 vapour pressure = Total pressure
In evaporator NH3 vapour pressure = Total pressure - partial pressure H2

For example, consider the condenser temperature at 50 0C, and evaporator temperature as -15 0C. The corresponding vapour pressures of NH3 are:
Condenser, Pk = 20.33bar; Evaporator outlet, Po2 = 2.6bar
The approximate pressures in various parts of the system then will be as given in the table.

It has been assumed that vapours leaving generator top are in equilibrium with entering rich solution at 40 C, at which temperature saturation pressure of NH3is 15.45bar. It has also been assumed that the temperature at evaporator inlet is -25 C at which temperature saturation pressure of NH3 is 1.516bar.
