AIR CONDITIONER WITH HEAT EXCHANGE IN SOIL AND WATER ENVIRONMENT Russian patent published in 2021 - IPC F24D3/18 F25B30/02 F25B30/06 

FIELD: thermal power engineering.

SUBSTANCE: invention relates to the field of thermal power engineering, in particular to installations that convert a low-potential thermal resource of the environment in order to ensure specified temperature conditions indoors. An air conditioner with heat exchange in the soil and water environment, containing a heat pump with a heat exchanger in the external environment and in the room air conditioning system, is made to form a single unit, including a housing inside which a heat-insulated cylinder is fixed coaxially with it, at the upper end of which a section with a diaphragm and an annular anchor, upper and lower parts are movably installed. The upper part is equipped with a heat exchanger, behind the inner wall of which there is a condenser, the lower part, immersed in an aqueous medium or in a water-saturated soil in heating mode, performs the function of an evaporator. An annular electromagnet, a fan and a compressor are placed on the upper end of the housing. The air conditioner is designed with the ability to switch the operating mode from heating to cooling by changing the transition between the evaporator and the condenser in the refrigerant circulation channel by closing or opening the free passage of the internal channel of the section into the condenser.

EFFECT: simplifying the design and ensuring the maintenance of a comfortable temperature regime in the premises at any time of the year.
