HEAT ACCUMULATOR Russian patent published in 2009 - IPC F24J3/08 

FIELD: heating.

SUBSTANCE: invention refers to heat power engineering and can be implemented in installations cooling living spaces and other premises in warm season of year and heating these premises in cold season. The heat accumulator consists of above ground heat exchanger coupled with a reverse cooling device along heat flow and also of buried into soil underground heat exchanger, forming a closed system together with pipelines connecting heat exchangers; the system is filled with working agent in form of fluid or its fumes; the underground heat exchanger is made in form of lowered and lifted pipes; the lowered pipe freely communicates with the above ground heat exchanger, while the lifted pipe communicates with above the ground heat exchanger via a facility containing accumulating-displacing vessel with devices facilitating motion of working agent in the direction from the lifted pipe to the accumulating-displacing vessel and in the direction from the accumulating-displacing vessel to the above ground heat exchanger and preventing motion of working agent in a reverse direction; also the accumulating-displacing vessel is either equipped with a facility of periodic heating and cooling of the vessel, or it has a branch with an evaporating section, communicated with the accumulating-displacing vessel; further the heat accumulator consists of a condensing section located behind the evaporating section and contacting with a source of heat energy, and of an accumulating-displacing section contacting with the source of heat energy and located behind the condensing section; the accumulating-displacing section is equipped with a device for periodic heating and cooling.

EFFECT: installation increases efficiency of cooling device in summer due to reduced temperature of condenser at withdrawing heat energy into soil in comparison of transferring heat energy to atmospheric air.
