Single Stage Absorption & Single Stage Desorption
Offered By Division T2

  • AARP with Single Stage Absorption & Single Stage Desorption are used for refrigeration temperature ranging from +5 to -55 Deg°C, heat source temperature requirement varies from 95 Deg°C to 180 Deg°C
     
    AARP With Single Stage Absorption & Single Stage Desorption
  • Liquid ammonia evaporates in the evaporator (HE1) to give the refrigeration effect.
  • These vapours are condensed (HE6) and liquid ammonia is stored in the receiver (V).
  • Ammonia vapours from evaporator are used for sub-cooling (HE2) the liquid ammonia supplied to evaporator. This improves energy efficiency of the AARP with Single Stage Absorption & Single Stage Desorption.
  • The receiver supplies liquid ammonia to evaporator.
  • Ammonia vapours are absorbed in absorber (HE3). The heat of absorption is removed by cooling water.
  • Weak ammonia solution in the desorber is sent to absorber for absorption.
  • The strong ammonia solution is pumped to desorber (HE4).
  • A solution heat exchanger (HE7) is provided to cool the weak solution before entering the absorber and preheat the strong solution before entering the desorber. This greatly improves of energy efficiency of the AARP with Single Stage Absorption & Single Stage Desorption.
  • Heat is supplied in the desorber to boil off the ammonia from strong solution. These vapours also contain some water vapours due to affinity between ammonia and water.
  • The traces of water in the evaporator are bleeding from evaporator to absorber through Bleed Heat Exchanger (HE8). Bleed Heat Exchanger further sub cools liquid ammonia and improves efficiency of AARP with Single Stage Absorption & Single Stage Desorption.
