Calculation of phace change heat accumulator in complex of energy efficient ventilation system

The classification of the main seasonal heat energy storage batteries is given, and the modern circuit diagram of the phaseshift battery as part of the system with a heat pump and a solar collector is considered. The disadvantage of water heaters istheir large volume in most cases. By utilizing the accumulated latent heat of substances, a significant reduction in capitalcosts is achieved. The possibility of creating energy-saving ventilation systems with the use of a seasonal heat accumulatorworking on phase transformations of heat-accumulating material is considered. The linear stationary mathematical model ofthe battery thermal balance is made and on the basis of the calculation results graphs and diagrams are constructed enablingtoanalyze the work of the heat accumulator during the year. The classification of the main seasonal accumulators of thermalenergy and ventilation systems with a ground heat exchanger use is considered. In the article the theoretical andcomputational research of the seasonal heat accumulator creation and application possibility working on phase transitions ofheat-accumulating substances (water) in the ventilation system of a residential individual house is given.
