    水冷式冷水機如何工作?
     
    How does water cooled chiller work?
     
    正如其名稱所示,水冷式冷水機組使用循環水來帶走工業設備或工藝產生的熱量,而空氣冷水機通過空氣散熱。
     
    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,水冷式冷水機組的工作周期如下:冷卻蒸發器中的工藝用水后的制冷劑蒸汽被吸入壓縮機,壓縮機的壓力和溫度都升高。
     
    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.
     
    然后將高壓高溫形式的制冷劑排放到冷凝器中。在那里,通過冷卻水除去熱量,冷卻水通過連接到室外水塔的另一個循環。
     
    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.
     
     
    然后制冷劑冷凝成液體并落在冷凝器的底部。通過孔(膨脹閥,履帶管),低壓制冷劑以蒸汽的形式進入蒸發器以執行其工作 - 冷卻工藝用水,然后重復循環。
     
    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,我們可以將冷水機組拆分為以下主要部件:壓縮機,冷凝器,膨脹閥,蒸發器,以及冷卻塔循環,冷卻塔及其輔助設備。
     
    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.
     
     
    壓縮機:
     
    compressor:
     
     
    由于喜好,在水冷式冷水機組中使用各種類型的壓縮機用于不同的情況。離心式,螺旋式,渦旋式或往復式是最常用的類型。每個人都有自己的優點和缺點。
     
    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.
     
     
    壓縮機提供冷水機的制冷功率。通過產生壓力差,它使制冷劑在系統周圍移動。
     
    The compressor provides the cooling power of the chiller. By creating a pressure difference, it moves the refrigerant around the system.
     
     
    壓縮機通常安裝在蒸發器和冷凝器之間。它作為驅動力連接到內部或外部電動機。
     
    The compressor is usually installed between the evaporator and the condenser. It is connected to an internal or external motor as a driving force.
    對于水冷式冷水機組,它采用水冷式殼管式冷凝器。
     
    For water-cooled chiller, it adopts water-cooled shell and tube condenser.
     
     
    殼管式冷凝器連接在壓縮機和膨脹閥之間。其功能是去除制冷劑從蒸發器中的工藝用水中吸收的熱量。
     
    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.

    在壓縮機壓縮制冷劑并將其送至冷凝器后,冷凝器使用空氣或水冷凝冰箱。
     
    After the compressor compresses the refrigerant and sends it to the condenser, the condenser uses air or water cooled condenser.
     
     
    對于水冷式冷水機組,冷凝器在室外與水塔連接,并將熱量從制冷劑傳遞到水塔。
     
    For water-cooled chillers, the condenser is connected to the water tower outdoors and transfers heat from the refrigerant to the tower.
     
     
    在冷凝水循環中,水在冷凝器和水塔之間重復地在管道內流動。水和制冷劑被管壁隔開。
     
    In the condensate cycle, water flows repeatedly in the pipe between the condenser and the tower. Water and refrigerant are separated by pipe walls.
     
     
    水在管道內流動,而管道上的制冷劑。制冷劑冷卻后,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.

    膨脹閥是水冷式冷水機組非常重要的制冷備件。
     
    Expansion valve is a very important spare part of water-cooled chiller.
     
     
    它位于冷凝器和蒸發器之間。它起到降低壓力和增加制冷劑體積的作用,該制冷劑在先前的連桿 - 冷凝器中冷凝成液體。
     
    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.

    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.

    蒸發器是通過制冷劑提取工藝用水的熱量的連接,并且冷卻的工藝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.
     
     
     
    工藝用水在冷卻循環中進出蒸發器。在蒸發器中,制冷劑在管道中運行,而殼體中的水則在管道中運行。
     
    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.
     
     
     
    水冷式冷水機有三種類型的蒸發器,帶線圈的不銹鋼水箱,閉環殼體,管式熱交換器和不銹鋼板式換熱器。
     
    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.
