在我们生活中的所有机器中,冷凝器是常用的类型之一,它根据各地的要求而有所不同。冷凝器的类型与产品的功能不同。我们生活中四种冷凝器的功能是什么?

Among all the machines in our life, condenser is one of the commonly used types, which varies according to the requirements of different places. The type of condenser is different from the function of the product. What are the functions of the four condensers in our life?

冷凝器作为制冷系统的重要组成部分之一,是一种热交换器。它还可以将气体或蒸汽变成液体。管中的热量通过淬火和回火的圆钢快速传递到管附近的空气中。由于冷凝器的工作过程是放热过程,因此冷凝器温度很高。

As an important part of refrigeration system, condenser is a kind of heat exchanger. It can also change gases or vapors into liquids. The heat in the tube is quickly transferred to the air near the tube through the quenched and tempered round steel. Because the working process of condenser is exothermic, the temperature of condenser is very high.

发电厂中使用了许多冷凝器来冷凝涡轮机排出的蒸汽。在制冷设备中,冷凝器用于冷凝制冷蒸汽,例如氨和氟利昂。在石油化学工业中,冷凝器用于冷凝碳氢化合物和其他化学蒸汽。在蒸馏过程中,将蒸汽转化为液体的装置也称为冷凝器。

Many condensers are used in power plants to condense the steam from the turbine. In refrigeration equipment, condenser is used to condense refrigeration steam, such as ammonia and Freon. In the petrochemical industry, condensers are used to condense hydrocarbons and other chemical vapors. In distillation, the device that converts steam into liquid is also called condenser.

冷凝器的不同类型及各自的作用

Different types of condensers and their functions

以上用于不同行业的所有冷凝器都是通过带走气体或蒸汽的热量来运行的,但是它们可以分为不同的类型。一种是水冷冷凝器,其中制冷剂释放的热量被冷却水带走。冷却水可以使用一次或循环使用。根据其结构的不同,可分为立式壳管型,卧式壳管型等。

All of the above condensers used in different industries operate by removing heat from the gas or steam, but they can be divided into different types. One is a water-cooled condenser in which the heat released by the refrigerant is taken away by the cooling water. Cooling water can be used once or recycled. According to the different structure, it can be divided into vertical shell and tube type, horizontal shell and tube type, etc.

另一个是风冷冷凝器,其中制冷剂释放的热量被空气带走。空气可以是自然对流,也可以是风扇强迫流动。它主要用于供水不方便或困难的氟利昂制冷设备中。

The other is an air-cooled condenser in which the heat released by the refrigerant is carried away by the air. Air can be either natural convection or forced flow by fans. It is mainly used in freon refrigeration equipment with inconvenient or difficult water supply.

还有一个水风冷冷凝器,其制冷剂同时由水和空气冷却,但主要取决于传热管表面上冷却水的蒸发,并从制冷剂中吸收大量热量侧为水汽化潜热;空气的作用主要是加快水的蒸发并带走水蒸气。

There is also a water air cooling condenser, whose refrigerant is cooled by water and air at the same time, but it mainly depends on the evaporation of cooling water on the surface of heat transfer tube, and absorbs a lot of heat from the refrigerant, and the latent heat of water vaporization is on the side; the role of air is to accelerate the evaporation of water and carry away water vapor.

因此,这种冷凝器的耗水量非常小,是空气干燥,水质低,水温低,水量不足的地区的首选冷凝器。这种冷凝器根据其不同的结构可分为蒸发式和淋水式。

Therefore, the water consumption of this kind of condenser is very small, and it is the first choice for the areas with dry air, low water quality, low water temperature and insufficient water quantity. This kind of condenser can be divided into evaporation type and drenching type according to its different structure.

此外,蒸发冷凝式冷凝器也是最常用的型号之一。它将依靠由另一制冷系统中的制冷剂的蒸发产生的冷却效果来冷却在热传递壁的另一侧上的制冷剂蒸汽,从而使后者冷凝并液化。级联制冷机中的蒸发是所用冷凝器的类型。

In addition, evaporative condensing condenser is one of the most commonly used models. It will rely on the cooling effect produced by the evaporation of refrigerant in another refrigeration system to cool the refrigerant vapor on the other side of the heat transfer wall, thus condensing and liquefying the latter. Evaporation in a cascade refrigerator is the type of condenser used.
