Description
Изобретение относитс к холодильной технике, а точнее к способам получени холода в абсорбционной холодильной установке .The invention relates to refrigeration, and more specifically to methods for producing cold in an absorption refrigeration unit.
Известны способы получени холода в абсорбционной холодильной установке путем двухстадийного выпаривани раствори: на первой стадии теплотой, выдел ющейс при абсорбции в цикле «превышени температур , а на второй - посторонним теплоносителем с одновременны.м отбором паров, образующихс на первой стадии выпаривани и подачей их в паровой поток, образующийс во второй стадии, последующей ректификации , дефлегмации и конденсации паров и испарени полученной жидкости при низком давлении с производством холода 1.There are known methods for obtaining cold in an absorption refrigeration unit by two-stage evaporation of the solution: in the first stage, the heat released during absorption in the cycle of temperature rises, and in the second stage by an external heat carrier with simultaneous removal of vapors formed in the first stage of evaporation and feeding them into vapor stream formed in the second stage, subsequent rectification, refluxing and condensation of the vapor and evaporation of the resulting liquid at low pressure with the production of cold 1.
Недостатком известных способов вл етс их мала экономичность вследствие больщой величины теплоты дефлегмации.A disadvantage of the known methods is their low efficiency due to the large heat of reflux.
Целью изобретени вл етс повыщение экономичности способа путем снижени теплоты дефлегмации.The aim of the invention is to increase the efficiency of the process by reducing the heat of reflux.
Указанна цель достигаетс тем, что отбор паров, образующихс на первой стадии выпаривани раствора, осуществл ют наThis goal is achieved in that the selection of vapors formed in the first stage of evaporation of the solution is carried out on
различных температурных услови х, и подают их на процесс ректификации в соответствующие температурные зоны потока паров хладагента, образующихс на второй стадии выпаривани .various temperature conditions, and they are fed to the rectification process to the corresponding temperature zones of the refrigerant vapor stream formed in the second evaporation stage.
На чертеже схематично представлена установка , в которой осуществл ют описываемый способ.The drawing shows schematically the installation in which the described method is carried out.
Установка содержит генератор I, ректификатор 2, дефлегматор 3, конденсатор 4, испаритель 5, абсорбер 6, теплообменник-регенератор 7, паровой перео.хладитель 8, смеситель 9, насос 10, отборы 11 -13 паров .хладагента и дроссельные вентили 14-16.The installation contains a generator I, a rectifier 2, a reflux condenser 3, a condenser 4, an evaporator 5, an absorber 6, a heat exchanger-regenerator 7, a steam re-cooler 8, a mixer 9, a pump 10, selections 11-13 refrigerant vapor and throttle valves 14-16 .
Установка работает следующим образом.The installation works as follows.
Пары хладагента из испарител 5 поступают частично в абсорбер 6, а оставша с часть - Б смеситель 9, где поглощаетс слабым раствором, который сюда поступает через дроссельный вентиль 14 из генератора 1. Выдел юща с при этом теплота абсорбции используетс на частичное выпаривание крепкого раствора, подаваемого в теплообменникрегенератор 7 насосом 10 из абсорбера 6.The refrigerant vapor from the evaporator 5 comes partly to the absorber 6, and the remaining part - B mixer 9, where it is absorbed by the weak solution that flows through the throttle valve 14 from generator 1. The heat of absorption absorbed is used to partially evaporate the strong solution, supplied to the heat exchanger regenerator 7 by the pump 10 from the absorber 6.
