Thermal Behaviour of a Heat Storage Floor Heated by an Air Flow

摘要

In the report, the heating system based on the circulation of air through a wall or a floor is considered theoretically. The energy consumption of a building can greatly be decreased throughout the year. The energy demand decreases during the spring and the autumn due to the solar heat without essential additional expenses. During the winter, the energy consumption can greatly be decreased by the intensification of the intermittent heating. During the summer, the energy consumption of the building can be decreased by storing the renewable cooling energy of the cooler nights for the day. The low temperature level of the heating system is also advantageous in connection with the district heating, the heating with biomass fuels, in heat pump heating and the solar heating. It is easy to add an electronic filter in the air based heating system, and the need for ventilation can be decreased, which causes additional savings. A computer program applicable for microcomputers is developed.
