ECO-FRIENDLY INDEPENDENT ENERGY-SAVING SYSTEM FOR COLD AND HEAT SUPPLY TO ROOMS WITH ARTIFICIAL ICE Russian patent published in 2014 - IPC F25D31/00 

FIELD: heating.

SUBSTANCE: system of cold and heat supply to rooms with artificial ice includes a low-temperature refrigerating machine with an evaporator, in which an antifreezing agent is cooled, which is used for artificial ice cooling, and heat that is emitted to atmosphere is formed in a condenser. A water cooling condenser is used in a low-temperature refrigerating machine. In a supply pipeline for discharge of heated water from it there installed are three outlet pipelines that are in-series connected to heat exchangers of induction terminals, an air heater of an air supply unit and to the heat exchanger, the second passages of which are connected as per a plenum pattern to a tap water supply pipeline. An outlet of the second passages for tap water heated in it is connected to the water condenser inlet of the refrigerating machine, the outlet of which is connected to a distributing header of a room hot water supply system. A drain place of warm water used in rooms is connected to a riser that supplies collected warm water to a receiving tank, to the lower part of which there connected is a pipeline with a supply pump of discharge heated water to the refrigerating machine evaporator, and the evaporator outlet is connected to a waste water outlet sewage collector.

EFFECT: use of this invention allows excluding natural environment pollution.
