Основной поток воздуха поступает в осушитель 1, где в процессе тепломассообмена с водным раствором хлористого лити , охлаждаемого обо ротной водой, происходит осушение воздуха и обводнение раствора. Затем осушенный воздух нагреваетс  в регенеративном теплообменнике 1, а при необходимости догреваетс  в подогревателе 2 и поступает в камеУдал емый из камеры воздух охлаждаетс  в теплообменнике 8, отдава  тепло воздуху, поступающему в десорбер 5. В результате тепломассообмена между воздухом и раствором, нагреваемым теплоносителем от внешнего источника, н десорбере происходит нагрев и увлажнение воздуха влагой , испарившейс  из раствора. Влажный нагретый-воздух через теп лообменник 7, где он охлаждаетс ,ОТ дава  тепло осушенному воздуху основ ного- потока, выбрасываетс  в атмосферу , а раствор, потер вший часть влаги, смешиваетс  с обводненным рас вором из осушител  1 и насосом подаетс  на обработку воздуха в осушителе 1 и десорбере 5б результате дополнительной установки двух регенеративных теплообмен ников и прин той схемы их размеще64 ни  расход тепла сокращаетс  на 600 ккал/г на 1 кг удал емой из продукта влаги. Формула изобретени  Установка дл  тепловлажностной обработки воздуха, содержаща  последовательно установленные по ходу основного потока воздуха осушитель, подогреватель и камеру с выт жным воздуховодом и десорбер, св занный контуром циркул ции абсорбента с осушителем, отличающа с  тем, что, с целью повышени  экономичности , она снабжена двум  регенеративными теплообменниками, один из которых установлен на выходе осушител  и десорбера, -а другой - в выт жном воздуховоде и подключен к входу десорбера. Источники информации, прин тые во внимание при экспертизе 1. Проспект фирмы А Johson Со. London Ltd, английское дочернее предпри тие Axel Johnson Group, Лондон, 1977, с. 3-18.The main air flow enters the dehumidifier 1, where in the process of heat and mass transfer with an aqueous solution of lithium chloride cooled with circulating water, the air is dried and the solution is flooded. The dried air is then heated in the regenerative heat exchanger 1, and, if necessary, it warms up in the heater 2 and enters the chamber. The air removed from the chamber is cooled in the heat exchanger 8, releasing heat to the air entering the desorber 5. As a result of heat and mass transfer between the air and the solution heated by heat carrier from the outside The source, on the desorber, heats and moistens the air with moisture evaporated from the solution. The moist heated-air through the heat exchanger 7, where it is cooled, FROM giving heat to the dried air of the main stream, is emitted into the atmosphere, and the solution, the lost part of the moisture, is mixed with the watered solution from the dryer 1 and the pump is fed to the air in the the desiccant 1 and desorber 5b as a result of the additional installation of two regenerative heat exchangers and the received scheme of their location64; the heat consumption is reduced by 600 kcal / g per 1 kg of moisture removed from the product. Claims An installation for heat-humid air treatment comprising a desiccant, a preheater and a chamber with an exhaust duct and a desorber connected in series along the main air flow, is connected to the circuit of the absorbent with a desiccant, which is equipped with two regenerative heat exchangers, one of which is installed at the outlet of the desiccant and desorber, and the other in the exhaust duct and connected to the desorber inlet.
