AIR CONDITIONER

FIELD: air conditioning. ^ SUBSTANCE: invention pertains to the technology of air conditioning. The air conditioner has a heat source device and a terminal device, joined by connection pipes for a coolant, in which there is exact determination of whether the contour of the coolant has the required amount of coolant or not. The conditioner can work, when switched in any of the normal working modes, in which the heat source device, consisting of a compressor and a lateral heat exchanger of the heat source device, is joined to terminal devices, consisting of lateral expansion valves and terminal lateral heat exchangers, using connection pipes. Each device is controlled depending on the work load of the terminal devices, or the working mode is determined by the quantity of the coolant, in which the terminal devices carry out cooling operations, and the running power of the compressor is regulated such that, the pressure during evaporation of terminal lateral heat exchangers is constant with control of lateral expansion valves such that, the degree of super heating on outlets openings of terminal lateral heat exchangers have a positive value. ^ EFFECT: accurate determination of whether the coolant contour has the required amount of coolant in a monofunctional conditioner. ^ 12 cl, 10 dwg
