水冷式冷水机如何工作?
 
How does water cooled chiller work?
 
正如其名称所示,水冷式冷水机组使用循环水来带走工业设备或工艺产生的热量,而空气冷水机通过空气散热。
 
As the name suggests, water-cooled chillers use circulating water to remove heat from industrial equipment or processes, while air chillers dissipate heat through air.

How does water cooled chiller work?
 
 
如上所述,水冷式冷水机组的工作周期如下:冷却蒸发器中的工艺用水后的制冷剂蒸汽被吸入压缩机,压缩机的压力和温度都升高。
 
As mentioned above, the working cycle of the water-cooled chiller is as follows: the refrigerant steam after cooling the process water in the evaporator is sucked into the compressor, and the pressure and temperature of the compressor increase.
 
然后将高压高温形式的制冷剂排放到冷凝器中。在那里,通过冷却水除去热量,冷却水通过连接到室外水塔的另一个循环。
 
The refrigerant in the form of high pressure and high temperature is then discharged into the condenser. There, the heat is removed by cooling water, which goes through another cycle connected to the outdoor water tower.
 
 
然后制冷剂冷凝成液体并落在冷凝器的底部。通过孔(膨胀阀,履带管),低压制冷剂以蒸汽的形式进入蒸发器以执行其工作 - 冷却工艺用水,然后重复循环。
 
The refrigerant then condenses into a liquid and falls on the bottom of the condenser. Through the hole (expansion valve, track pipe), the low-pressure refrigerant enters the evaporator in the form of steam to perform its work - cooling the process water and then repeating the cycle.

因此,我们可以将冷水机组拆分为以下主要部件:压缩机,冷凝器,膨胀阀,蒸发器,以及冷却塔循环,冷却塔及其辅助设备。
 
Therefore, we can divide the chiller into the following main components: compressor, condenser, expansion valve, evaporator, cooling tower circulation, cooling tower and its auxiliary equipment.
 
 
压缩机:
 
compressor:
 
 
由于喜好,在水冷式冷水机组中使用各种类型的压缩机用于不同的情况。离心式,螺旋式,涡旋式或往复式是最常用的类型。每个人都有自己的优点和缺点。
 
Due to preference, various types of compressors are used in water-cooled chillers for different situations. Centrifugal, spiral, scroll or reciprocating are the most commonly used types. Everyone has his own advantages and disadvantages.
 
 
压缩机提供冷水机的制冷功率。通过产生压力差,它使制冷剂在系统周围移动。
 
The compressor provides the cooling power of the chiller. By creating a pressure difference, it moves the refrigerant around the system.
 
 
压缩机通常安装在蒸发器和冷凝器之间。它作为驱动力连接到内部或外部电动机。
 
The compressor is usually installed between the evaporator and the condenser. It is connected to an internal or external motor as a driving force.
对于水冷式冷水机组,它采用水冷式壳管式冷凝器。
 
For water-cooled chiller, it adopts water-cooled shell and tube condenser.
 
 
壳管式冷凝器连接在压缩机和膨胀阀之间。其功能是去除制冷剂从蒸发器中的工艺用水中吸收的热量。
 
The shell and tube condenser is connected between the compressor and the expansion valve. Its function is to remove the heat absorbed by the refrigerant from the process water in the evaporator.

在压缩机压缩制冷剂并将其送至冷凝器后,冷凝器使用空气或水冷凝冰箱。
 
After the compressor compresses the refrigerant and sends it to the condenser, the condenser uses air or water cooled condenser.
 
 
对于水冷式冷水机组,冷凝器在室外与水塔连接,并将热量从制冷剂传递到水塔。
 
For water-cooled chillers, the condenser is connected to the water tower outdoors and transfers heat from the refrigerant to the tower.
 
 
在冷凝水循环中,水在冷凝器和水塔之间重复地在管道内流动。水和制冷剂被管壁隔开。
 
In the condensate cycle, water flows repeatedly in the pipe between the condenser and the tower. Water and refrigerant are separated by pipe walls.
 
 
水在管道内流动,而管道上的制冷剂。制冷剂冷却后,落入冷凝器的槽中并被收集。
 
Water flows in the pipe, and the refrigerant on the pipe. As the refrigerant cools, it falls into a slot in the condenser and is collected.

热膨胀阀:
 
Thermal expansion valve:
 
 
膨胀阀是水冷式冷水机组非常重要的制冷备件。
 
Expansion valve is a very important spare part of water-cooled chiller.
 
 
它位于冷凝器和蒸发器之间。它起到降低压力和增加制冷剂体积的作用,该制冷剂在先前的连杆 - 冷凝器中冷凝成液体。
 
It is located between the condenser and the evaporator. It reduces the pressure and increases the volume of refrigerant, which condenses into a liquid in the previous connecting rod condenser.

通过膨胀阀,制冷剂可以作为蒸汽进入蒸发器并从过程水中吸收热量。可提供不同类型的膨胀阀,例如热力膨胀阀,电子阀,先导式膨胀阀和孔式膨胀阀,履带式管道等。
 
Through the expansion valve, refrigerant can enter the evaporator as steam and absorb heat from the process water. Different types of expansion valves are available, such as thermal expansion valve, electronic valve, pilot expansion valve and orifice expansion valve, crawler type pipeline, etc.
 
最受欢迎的热膨胀阀品牌是丹佛斯和艾默生。
 
The most popular thermal expansion valve brands are Danfoss and Emerson.

蒸发器:
 
Evaporator:
 
 
蒸发器是通过制冷剂提取工艺用水的热量的连接,并且冷却的工艺用水被泵送到需要的地方。
 
The evaporator is connected by extracting heat from the process water by refrigerant, and the cooling process water is pumped to the required place.
 
 
 
工艺用水在冷却循环中进出蒸发器。在蒸发器中,制冷剂在管道中运行,而壳体中的水则在管道中运行。
 
The process water flows in and out of the evaporator during the cooling cycle. In the evaporator, the refrigerant runs in the pipe, while the water in the shell runs in the pipe.
 
 
 
水冷式冷水机有三种类型的蒸发器,带线圈的不锈钢水箱,闭环壳体,管式热交换器和不锈钢板式换热器。
 
Water cooled chillers have three types of evaporators, stainless steel water tanks with coils, closed-loop shells, tubular heat exchangers and stainless steel plate heat exchangers.
 
 
 
这取决于客户要求和项目现场条件,以选择适合您的水冷式冷水机的冷凝器类型。
 
This depends on customer requirements and project site conditions to select the type of condenser suitable for your water-cooled chiller.
