FIELD: heating.
SUBSTANCE: group of inventions relates to a heating device with irreversible thermodynamic cycle. The device comprises a low-temperature circuit and a high-temperature circuit, where first and second working media circulate accordingly. Each circuit comprises a facility of evaporation, compression, condensation and expansion of the appropriate working medium. The low-temperature circuit absorbs heat from supplied water flow for evaporation of the first working medium. Heat extracted during condensation of the first working medium is used to evaporate the second working medium. At the same time heat extracted in process of condensation is used to heat the supplied water flow. In accordance with the invention two working circuits contain each a cooling facility placed between the appropriate means of condensation and expansion. Such cooling device is in thermal contact with independent partial flows of supplied water flow for heating of the latter in general due to heat removed from working media circulating in two circuits.
EFFECT: group of inventions is aimed at provision of simultaneous generation of high temperature of supply and high values of heating installation transformation ratio.
