Description

Изобретение относится к холодильной технике, конкретнее — к способу работы гелиоэжекторной холодильной фашины.The invention relates to refrigeration, and more particularly, to a method of operating a solar ejector refrigeration fascia.

Известен способ одновременного получения холода и горячей воды с помощью компрессионных холодильных машин, при котором одновременное получение холода и горячей воды обеспечивается работой холодильной машины и отводом горячей воды от конденсаторов с водным охлаждением £1J .A known method for the simultaneous production of cold and hot water using compression refrigeration machines, in which the simultaneous production of cold and hot water is provided by the operation of the refrigeration machine and the removal of hot water from condensers with water cooling £ 1J.

Однако температура горячей воды, полученной таким способом, ограничена 30-40°С, так как повышение температуры конденсации приводит к снижению энергетической эффективности холодильного цикла.However, the temperature of the hot water obtained in this way is limited to 30-40 ° C, since an increase in the condensation temperature leads to a decrease in the energy efficiency of the refrigeration cycle.

По своей механической сущности наиболее близок к предлагаемому способ одновременного получения холода и горячей воды с помощью солнечной энергии путем кипения холодильного агента в генераторе при нагреве его теплоносителем, подаваемым из солнечного нагревателя, отсоса и' сжатия пара из испарителя в эжекторе, сжижения смеси в охлаждаемом водой конденсаторе с последующей подачей одной части холодильного агента через регулирующий вентиль в испаритель и эжектор, а другой — в генератор £2] .By its mechanical nature, the closest to the proposed method is the simultaneous production of cold and hot water using solar energy by boiling a refrigerant in a generator when it is heated with a coolant supplied from a solar heater, suction and compressing steam from an evaporator in an ejector, and liquefying the mixture in cooled water a condenser with the subsequent supply of one part of the refrigerant through the control valve to the evaporator and ejector, and the other to the generator £ 2].

Однако в нем не предусмотрено использование тепла, выделяемого в конденсаторе, так как охлаждение конденсатора осуществляется либо оборотной водой, либо’отепленная в кон.» денсаторе вода сбрасывается в водоем.However, it does not provide for the use of heat generated in the condenser, since the cooling of the condenser is carried out either with circulating water or “heated to the end.” water is discharged into the reservoir.

^υ Цель изобретения — повышение экономичности. ^υ The purpose of the invention is improving efficiency.

Поставленная цель достигается тем, что воду после конденсатора подают в солнечный нагреватель, затем в ка15 честве теплоносителя — в генератор, после чего направляют ее потребителю.This goal is achieved by the fact that the water after the condenser is supplied to the solar heater, then, as a heat carrier, to the generator, after which it is sent to the consumer.

На чертеже представлена машина, в которой осуществляется предлагаемый способ.The drawing shows a machine in which the proposed method is implemented.

Машина содержит солнечный нагреватель 1 и водяной насос 2, а также последовательно · расположенные генератор 3 рабочего пара, эжектор 4, 25 конденсатор 5 с водяным охлаждением, регулирующий вентиль 6, испаритель 7, насос 8 для подачи жидкого холодильного агента в генератор 3.The machine contains a solar heater 1 and a water pump 2, as well as sequentially arranged working steam generator 3, an ejector 4, 25 a water-cooled condenser 5, a control valve 6, an evaporator 7, and a pump 8 for supplying a liquid refrigerant to the generator 3.

Способ осуществляется следующим образом.The method is as follows.

Насыщенный рабочий пар из генера-т тора 3 подают в эжектор 4, где он отсасывает пары из испарителя 7, сжимает их и направляет на сжижение в конденсатор 5, после чего одну часть холодильного, агента через регулирую- щий вентиль 6 подают в испаритель 7, ^Эа другую насосом 8 в генератор 3. Охлаждающую воду после конденсатора 5 направляют насосом 2 в солнечный на‘греватель 1, а затем-в генератор 3, где она отдает часть тепла кипящему холодильному агенту и подается потребителю. Регулирование давления в генераторе осуществляется байпасированием части горячей воды.Saturated working steam from the generator 3 is fed into the ejector 4, where it sucks the vapors from the evaporator 7, compresses them and directs them to liquefaction in the condenser 5, after which one part of the refrigerant is fed through the control valve 6 to the evaporator 7, ^E and another pump 8 to the generator 3. The cooling water after the condenser 5 is sent by the pump 2 to the solar heater 1, and then to the generator 3, where it gives part of the heat to the boiling refrigerant and is supplied to the consumer. The pressure in the generator is regulated by bypassing part of the hot water.

Таким образом, вследствие исполь- 15 зованкя ранее сбрасываемого тепла конденсации (количество которого равно сумме количеств тепла, подведенных в генераторе и испарителе), и повышения его температурного уровня 20 в солнечном нагревателе, гелиоэжекторная машина производит не только холод, но и горячую воду.Thus, due to the use of the 15 filling of previously condensed heat (the amount of which is equal to the sum of the amounts of heat supplied in the generator and the evaporator) and the increase in its temperature level of 20 in the solar heater, the solar ejector produces not only cold, but also hot water.

Claims
