Rational technology of effective application of thermal accumulator in the system of conditioning andhot water-supply of building in a warm period of year is analytically analyzed and grounded. Analyzed thepossibility of applying such an unconventional method as daily accumulation of thermal energy of the building'sair-conditioning system during the warm period with its subsequent use in the hot water system. Two technologiesfor heat recovery of the air conditioning system for hot water supply of a building using a heat accumulator wereinvestigated: with a constant volume of heat accumulator and variable condensing temperature of the refrigerantof the air conditioning system depending on the outside air temperature and heat recovery technology with avariable volume of heat accumulator and constant temperature condensation temperature of the refrigerantsystem conditioning. The research results showed the most efficient technology for utilization of heat from an airconditioning system with a variable volume of a heat accumulator, which is 35% more cost effective than atechnology with a constant heat accumulator cost of reference fuel. The possibility of real application of thesetechnologies, both in individual houses and apartments, was also grounded. Using the developed automatedmethod, it was certain that application of thermal accumulator in the complex system of conditioning and hotwater-supply in a warm period would allow assured to provide by hot water of users due to the system ofconditioning and will economize from 74% to 82 % conditional fuel as compared to a chart with a caldron andconditioner without a thermal accumulator.
