SUB-ATMOSPHERIC SYSTEM OF HEAT AND COLD SUPPLY Russian patent published in 2018 - IPC F24D1/02 F25B29/00 F25B15/04 

FIELD: ventilation.

SUBSTANCE: sub-atmospheric system of heat and cold supply for air conditioning relates to heat power engineering, namely to power-saving technologies, and is intended for usage in autonomous heating, hot water supply and cold supply of residential, public and industrial buildings. To implement effective heat supply, a vacuum-steam method of heat transfer by steam with an adjustable depth of vacuum is applied, efficiency of heat supply subsystem reaches 0.9.

EFFECT: combined with the subsystem of heat supply, the subsystem of cooling supply, including the installation of a pumpless absorption water-cooling refrigerating machine and the system of air coolers of indirect evaporative cooling in a vacuum environment, while ensuring energy efficiency with an EER of 12, 5 kW/kW.
