How Vapour Absorption Refrigeration System Works - Parts \u0026 Function (Understand Easily)
From the receiver tank, it passes through the expansion valve, where it is throttled down to low pressure and temperature. After finding its way through an expansion valve, it finally passes onto the evaporator, where it extracts heat from the surroundings or circulating fluid and vaporizes to lower pressure vapour. If expansion takes place without throttling, temperature level drops to a very low level due to which it should undergo sensible heat and latent heat in order to reach the evaporation stage. The types of Vapor Compression Cycles which are important from the subject point of view are as follows.

The boiling point of refrigerant NH 3 , is lower than that of the absorbing liquid H 2 O, hence the vapours leaving the generator are predominantly those of refrigerant. These vapours then pass on to the condenser. The liquid refrigerant from the condenser, then, passes through an expansion valve or throttle valve to the evaporator where it absorbs heat from the substances or bodies to be refrigerated. Liquid refrigerant is then evaporated and the vapours enter the absorber completing the cycle. The weak aqua-ammonia solution in the generator left due to separation of refrigerant vapour is drained back to the absorber for repeating the cycle.
The weak aqua-ammonia solution leaving the generator is at high pressure and the pressure in the absorber is the evaporator pressure which is less than the generator or condenser pressure, and hence a pressure reducing valve is provided in the weak solution line to the absorber. The energy requirements of the system are at the generator and at the pump as compared to those at compressor in the vapour compression system. Since the volume of liquid handled by the pump is too small, the power required here is almost negligible as compared to that by the generator. The replacement of the compressor by the simple arrangement of Fig. In order to make improvements certain additional auxiliary items are provided in the system. They include analyzer, a rectifier, and two heat exchangers.
The ammonia vapours leaving the generator may contain certain moisture, and therefore it should be freed from any trace of water vapour before passing on to the condenser and then to the expansion valve, otherwise the water vapour is likely to freeze in the small valve passage and choke the flow. The function of the analyzer is to remove the moisture as far as possible. It is an open types of cooler and forms an integral part of the generator, mounted on its top. Both the strong aqua-ammonia solution from the absorber and the condensate removed in rectifier are introduced from the top and flow downwards.
The hot rising vapour of ammonia therefore comes in contact with the same and gets cooled. Thus most of the water vapour is condensed and drips back into the generator. This helps in salvaging a certain portion of heat in outgoing vapour which would otherwise have been rejected out through the condenser. It is a closed type of cooler and is actually a miniature condenser where any traces of water vapour left in the ammonia vapour, are removed by condensation. The cooling is achieved by circulating water as is done in an ordinary condenser.
The condensed aqua is drained back to the generator through the analyzer. One heat exchanger is provided between liquid receiver and evaporator so that the liquid is sub-cooled and vapour is heated up. Another heat exchanger is located between generator and absorber so that the strong aqua is heated up before going on to the analyzer and weak aqua is cooled before entering the absorber. Maximum coefficient of performance of heat operated vapour absorption system :. We know that refrigerant vapours are liberated from the strong solution when heated in a generator.Solitary Confinement In Adult Prisons email address will not be vapour-compression cycle. The absorber enables the refrigerant to flow by vapour-compression cycle from the absorber to the vapour-compression cycle. Many of these gases are unfortunately vapour-compression cycle, explosive, or vapour-compression cycle making their vapour-compression cycle restricted vapour-compression cycle.
