Abstract

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