Energy storage is one of the most important issues related to modern energy. The major change from sources of
constant generation energy into favor of sources with variable powers (wind or solar power plants) causes a greater than
before need for energy storage systems. The article focuses on averaging energy consumption by air-conditioning
installations in a single-family house. In a standard air conditioning system based on a compressor device, the demand for
electric power is proportional to the demand for cooling power. If a cold store is used, it is possible to balance the electricity
demand. The use of a cold storage in the form of a sorption bed means that the building uses a constant amount of electric
energy just for ventilation system. The analysis showed that if there is needed to store 47.8 kWh of cold, its volume (in case
it is built of silica gel) must be 3.78 m3. This solution not only causes that the energy consumption is equalized, but also
significantly reduces electricity consumption.
