Description
Известен способ получени -низких температур в холодильных установках , у которых примен ютс термодинамические циклы с неазеотролными смес ми.A known method of producing low temperatures in refrigeration units, in which thermodynamic cycles with non-azerol mixtures are used.
Предлагаемый способ получени низких температур в одноступенчатой пароком прессорной холодильной установке отличаетс использованием в качестве рабочего тела неазеотропной бинарной смеси холодильных агентов, один из которых вл етс вьгсококип щим, а второй-низкокин щим с температурой испарени на 8-10° ниже минимальной требуемой температуры.The proposed method for producing low temperatures in a single-stage steam pressory refrigeration unit is characterized by using non-azeotropic binary mixture of refrigerants as working medium, one of which is ultra-low boiling and the second low-condensing with an evaporation temperature 8-10 ° below the minimum required temperature.
Это позвол ет снизить температуру испарени при допустимой степени сжати одноступенчатого компрессора.This makes it possible to reduce the evaporation temperature at a permissible degree of compression of the single-stage compressor.
Кроме этого способом предусмотрена возможность конденсации низкокип щего компонента путем использовани холода высококип щего компонента, а конденсацию высококип щего компонента осуществл ть в конденсаторе, охлаждаемом водой.In addition, the method provides for the possibility of condensation of a low boiling component by using the cold of the high boiling component, and the condensation of the high boiling component in a condenser cooled by water.
По предлагаемому способу высококип щий компонент, конденсируемый в конденсаторе, проходит через конденсатор-испаритель и отсасываетс компрессором. Низкокип щий компонент конденсируетс в конденсаторе-испарителе за счет холода испарени высококип щего компонента и нанравл етс в рессивер, откуда дросселируетс в испаритель . По выходе из испарител нары низкокип щего компонента проход т через змеевик, встроенный в его рессивер, выполн ющий роль рекуператора холода, и отсасываютс компрессором.In the proposed method, a high boiling component condensed in a condenser passes through a condenser-evaporator and is sucked off by a compressor. The low-boiling component is condensed in the condenser-evaporator due to the cold evaporation of the high-boiling component and put into the receiver, from where it is throttled into the evaporator. Upon leaving the evaporator, the bunks of the low-boiling component pass through a coil built into its receiver, which acts as a cold recuperator, and is sucked off by a compressor.
Система регулирующих вентилей дает возможность направл ть в основной испаритель как один из компонентов, так и х смесь, что позвол ет легко регулировать температурный уровень аппарата, получать оптимальные разности температур и различные значени холодоп р оиз водител ьности.The system of control valves makes it possible to direct both one of the components and the mixture to the main evaporator, which makes it possible to easily control the temperature level of the apparatus, to obtain optimum temperature differences and different values of the cooling system.
