FIELD: heat and hot water supply systems.
SUBSTANCE: invention relates to heat and heat water supply systems of dwelling houses and production complexes. Proposed self-contained heating and hot-water supply of dwelling house includes use of heat of combustion products of heat generator for heating air and water heat carriers. In summer and in heating periods, combustion products are cooled in water heater consisting of convection, condensing stages and contact chamber to temperature at which vapors are condensed on heating surface of condensing stage. In summer these vapors are removed through contact chamber, and water designed for hot water supply is heated. Said water is heated by counterflow in succession in condensing and conversion stages of water heater by heat of combustion products. In heating period, contact chamber is disconnected, and heating of water for hot water supply is carried out as in summer period, and through air heater in form of tube-in-tube recuperative heat exchanger consisting of set of sections of heat exchanger elements of convection and condensing stages and contact chamber in between, combustion products heat successively air heat carrier by counterflow. Amount of heat received by each heat carrier is regulated by bypass gas line connecting convection and condensing stages of water heater. Air heating system for implementing proposed method is described in invention.
EFFECT: elimination of heat losses from air heater owing to arrangement of all devices and communications inside house, reduced cost of heating and hot water supply.
