Description

Изобретение относитс  к области холодильной техники и направле)ю па снижение металлоемкости испарител , хладагентом в котором  вл етс  вода.The invention relates to the field of refrigeration and the direction of reducing the metal intensity of an evaporator, in which water is a coolant.

Известны способы интенсификации теплообмена в испарителе абсор.бционной холодильной машины, например бромистолитиевой , путем введени  в хладагент присадок.Methods are known for intensifying heat transfer in an evaporator of an absorber chiller, for example, a bromine lithium cooler, by introducing additives into the refrigerant.

Предлагаемый способ позвол ет повысить коэффициент теплоотдачи. Это достигаетс  тем, что в качестве присадок используют поверхностно-активные .вещества, например алкилсульфонат , который ввод т в количестве 0,2-0,5% от веса воды в испарителе.The proposed method allows to increase the heat transfer coefficient. This is achieved by using surface-active substances as additives, for example, an alkyl sulfonate, which is introduced in an amount of 0.2-0.5% by weight of water in the evaporator.

Способ осуществл ют следующим образом.The method is carried out as follows.

В испаритель бромистолитиевой абсорбциоиной холодильной установки, в которой хладагентом  вл етс  вода, ввод т поверхностно активное вещество - алкилсульфонат (СпП2п+ 5ОзМа) в количестве 0,2-0,57о от веса воды , залитой в испаритель.In the evaporator of a bromide-lithium absorption refrigeration unit, in which the refrigerant is water, a surfactant, an alkylsulfonate (SpP2p + 5OzMa), is added in an amount of 0.2-0.57 ° by the weight of water poured into the evaporator.

Указанное вещество обеспечивает развитое пузырьковое кипение и повышает коэффициент теплоотдачи от стенки к воде в 1,9-6 раз при нзменении тепловой нагрузки в 13 раз (3200-40000 Вт/м2).The specified substance provides developed bubble boiling and increases the heat transfer coefficient from wall to water by 1.9-6 times with a 13-fold decrease in heat load (3200-40000 W / m2).

Ф О р м} л а изобретен и  F.Orm} l and invented

Способ интенсификации теплообмена в испарителе абсорбционной холодильной машины , например бромистолитиевой, путем введени  в хладагент присадок, отличающийс  тем, что, с целью повышени  коэффициента тенлоотдачи при использовании в качестве хладагента воды, в качестве присадок используют поверхностно-активные вещества , например алкилсульфонат, который ввод т в количестве 0,2-0,5% от веса воды в испарителе.A method of intensifying heat exchange in an evaporator of an absorption chiller, for example, bromole-lithium, by introducing additives into a refrigerant, characterized in that, in order to increase the coefficient of tenloration when using water as the refrigerant, surfactants, such as alkyl sulfonate, are used as additives in the amount of 0.2-0.5% by weight of water in the evaporator.
