Techniques related to elimination of environmental pollution are divided into two main trends. These are primary and secondary solutions. Primary solutions are based on the creation / selection of technologies that do not emit pollutants, secondary solutions are used in the situation that pollutants are already generated. Elimination is made by selected technological processes. When using residential, office or industrial buildings, emissions are primarily associated with the use of energy carriers such as electricity, heat or cold. During electricity production, pollution is related mostly to the atmosphere degradation. Thus, any solution that reduces energy consumption or improves the energy efficiency of buildings is the primary method of environment protection. This article proposes and investigates an idea of cold storage system based on an adsorbent bed (silica gel), which aims to reduce the energy consumption of the domestic air conditioning system. As a result of experimental research, it was shown that for a building with a volume of 1000m 3 and multiples of air exchanges at 0.5 level, a silica gel bed with a volume of 1.63 m3 is required in order to continuously unload the air conditioning system for 8 hours (while outside air temperature exceeding 25oC).
