Claims (2)

Кроме того, дл  работы установки необходимы насос 18 дл  -перекачивани  слабого раствора из абсербера 8 в генератор 3, распределительный коллектор 19, вакуумнасос 20 и трубопроводы 21 и 22 соответственно дл  теплой технологической воды, поступающей в испаритель 9 и дл  охлажденной воды, отход щей от испарител  9. Установка работает следующим образом . Летний период. Насосом 18 из абсорбера 8 забираетс  слабый водный раствор хлористого лити  и нагнетаетс  через теплообменник-регенератор 7 по линии б в распределительный коллектор 19, откуда сливаетс  в генератор 3, размещенный на крыше 1 здани  2. Слива сь вниз по поверхности генератора 3,раствор частично «обезвоживаетс  под действием солнечной энергии, поступающей в генератор 3 через прозрачный экран 4,и под действием предварительно нагреваемого воздуха на участке зачерненной плиты 11, котора  в свою очередь нагреваетс  солнечной энергией, проход щей через прозрачный экран 12. В это врем  продухи 14 и 15 закрыты заслонками 16 и 17. Наружный воздух поступает в нижнюю часть Г-образного канала 13 и выходит в атмосферу насыщенным вод ными парами из его верхней части. Образующийс  в генераторе 3 крепкий раствор по линии 5 поступает через теплообменник-регенератор 7 в абсорбер 8, в котором, слива сь по теплообменной поверхности, охлаждаемой водой, поглощает пары технологической воды, котора  самоиспар етс  под глубоким вакуумом, и охлажденным направл етс  к потребителю холода по линии 22. В корпусе 10 имеетс  глубокий вакуум, при котором тепла  технологическа  вода, поступающа  по линии 21 в испаритель 9, самоиспар етс , охлажда сь до 10-12°С, и используетс  дл  кондиционировани  воздуха в здании 2. Дл  удалени  проникающего в корпус 10 воздуха служит вакуумнасос 20. Зимний период. Заслонки 16 и 17 открыты и образуют замкнутый контур циркул ции воздуха через Г-образный канал 13, продухи 14 и 15 и внутренний объем здани  2. При этом воздух нагреваетс  в Г-образном канале 13 проникающей через прозрачные экраны 12 и 4 солнечной энергией и после этого отапливает внутренний объем здани  In addition, for the operation of the installation, a pump 18 is required for pumping a weak solution from the aberber 8 to the generator 3, the distribution manifold 19, the vacuum pump 20 and the pipes 21 and 22, respectively, for the warm process water entering the evaporator 9 and for the cooled water coming from evaporator 9. Installation works as follows. Summer period The pump 18 from the absorber 8 takes a weak aqueous solution of lithium chloride and is pumped through the heat exchanger-regenerator 7 through line B to the distribution manifold 19, from where it is poured into the generator 3 located on the roof 1 of the building 2. The drain is down the surface of the generator 3, the solution is partially " dehydrated by solar energy entering generator 3 through transparent screen 4, and under the action of pre-heated air in the area of blackened plate 11, which in turn is heated by solar energy passing through Res transparent screen 12. At this time, the air holes 14 and 15 are closed valves 16 and 17. Outside air enters the bottom of the L-shaped channel 13 and exits to atmosphere saturated water chambers pairs of an upper portion thereof. A strong solution formed in generator 3 through line 5 flows through heat exchanger-regenerator 7 to absorber 8, in which, draining from heat-exchanging surface cooled by water, absorbs process water vapor, which self-evaporates under high vacuum, and is cooled to the consumer of cold through line 22. In case 10 there is a deep vacuum, in which the process water coming through line 21 to the evaporator 9 is self-evaporated, cooled to 10-12 ° C, and is used to condition the air in the building 2. For and penetrating into the housing 10 serves as the air vacuum pump 20. The winter period. The dampers 16 and 17 are open and form a closed loop of air circulation through the L-shaped channel 13, ports 14 and 15 and the internal volume of the building 2. At the same time, the air is heated in the L-shaped channel 13 by solar energy penetrating through the transparent screens 12 and 4 this heats the internal volume of the building 2. Холод в это врем  не производитс , насос 18 не работает. Экономический эффект от внедрени  изобретени  выражаетс  в снижении стоимости тепла и холода, вследствие круглогодичной эксплуатации установки.
