Energy consumption in buildings has been increased due to HVAC systems in recent years with the development of the economy worldwide Air-conditioning is provided by electrically-driven vapor-compression air conditioning unit especially during the summer. Electrically driven VCR requires high grade energy and it also damage our environment. On other hand thermally driven adsorption refrigeration and absorption refrigeration systems got considerable attention nowadays not due to its manufacturing simplicity, but also having environment friendly adsorbent/refrigerant pairs. The present work is focused towards the development of a prototype of vapour adsorption refrigeration system and design of the innovative vapor absorption system using aqua ammonia and a prototype of 1 KW capacity has been designed, developed and tested in the laboratory for vapour adsorption as well as absorption systems. In the present work the heating time required to achieve the cooling effect is around 10 minutes. The COP of the system is in the range of 0.08 to 0.190. The major problem in absorption system is that, along with the ammonia, water also enters into the condenser and the evaporator tube which hampers the cooling effect.

Keywords: Absorption, Adsorption, Ammonia-water
