AIR CONDITIONER WITH HYBRID DESICCANT AND EVAPORATIVE COOLING SYSTEM Russian patent published in 2017 - IPC F24F5/00 

FIELD: ventilation.

SUBSTANCE: air conditioner with a hybrid system of desiccant and evaporative cooling contains supply and exhaust chambers separated by a horizontal intermediate partition with a main and additional windows, a desiccant and evaporative cooling system, an exhaust air heater unit, and two adiabatic humidifiers of exhaust and supply air. The supply and exhaust chambers contain inlet and outlet nozzles, air cleaners, and fan units. The system of dessicant and evaporative cooling is made hybrid; in the main window of the partition the recuperative heat exchanger is placed, which is made in the form of a plate-type three-stage counterflow recuperator of V-type design, containing two plate-type counterflow heat exchangers, arranged vertically and in a row, and hermetically connected to them from below through intermediate nozzles closing diagonally installed plate-type cross-flow heat exchanger. In addition, the main window in the air conditioner partition is made with two vertical transverse walls lowered downwards, the ends of which are hermetically connected to the side walls of the air conditioner, and is separated by a vertical transverse partition that is made over the whole width of the air conditioner, and on a horizontal link, that connects two vertically arranged plate-type counterflow heat exchangers, a vertical transverse partition, with a connecting groove in its upper part, is installed. The floor panel of the air conditioner is equipped with a mounting window with flanges, and the hanging housing of the plate-type three-stage recuperator is hermetically connected by its flanges to the flanges of the mounting window in the floor panel of the air conditioner with the additional integration of the two lowered vertical transverse walls of the main window of the horizontal intermediate partition of the air conditioner into the connecting grooves of the vertical links of vertically mounted plate-type counterflow heat exchangers of a three-stage plate-type recuperator, and integration of the lower end of vertical transverse partition of the air conditioner into the connecting groove of the vertical transverse partition of the three-stage plate-type recuperator shell, with the formation of three hermetic connections "to the lock" and output air channels from the three-stage plate-type counterflow heat exchanger to the exhaust and supply air chambers.

EFFECT: increasing the energy efficiency of the desiccant and evaporative cooling system of air conditioner in the cold and warm periods of the year.
