AIR CONDITIONER-HEATER Russian patent published in 2007 - IPC F24F5/00 F24D15/04 

FIELD: mechanical engineering; reversible air conditioners.

SUBSTANCE: proposed air conditioner-heater consists of heat exchanger installed inside room and operating in summer period as evaporator, and external heat exchanger with fan operating in summer period as condenser, working medium, compressor with electric drive, four-way valve and branch pipes connecting above-indicated sets into common plant with possibility of reversing to make external heat exchanger operate as evaporator in cold seasons. Air conditioner-heater includes therosiphons in form of vertical gravity heat pipes whose evaporating parts are driven into ground, and condensing parts project over surface of ground being furnished with heat exchangers with air. Condensing parts of heat pipes with heat exchangers are enclosed, together with outer heat exchanger and fan, in sealed heat-insulated hood furnished with hatches to pass outer air into inner space of hood, when hatches are opened.

EFFECT: increased thermal energy transformation coefficient.
