工业冷水机您知道多少?

    螺杆式冷水机的主要技术参数

    For all,外行看热闹 内行看门道,在机械工业领域,要是想详细的了解机器的话,最好的就是了解它的技术参数,工业冷水机也不例外,我们现在很多人都开始使用螺杆式冷水机,但是我们了解螺杆式冷水机吗?知道它的技术参数吗?小编就带你走进无锡朝腾机械了解一下工业冷水机的主要参数简单介绍一下:

螺杆式冷水机

     一、制冷能力

    它是螺杆式冷水机一个很重要的技术参数,其可以关系到整台机组的工作效率。制冷能力主要表现在制冷量,也就是在一定工况下,冷水机组单位时间内从被冷却物体吸取的热量,单位为kw/h,我们也会经常使用Kcal/h(1kw/h=860Kcal/h)。制冷量是随着冷水机组类型和规格的不同来决定,所以用户想要达到自己的制冷需求,应该根据实际需求选择适合自己的冷水机组。

    二、输入功率、耗电量

    对于螺杆式冷水机而言,输入功率是指所有压缩机轴功率之和,单位为kw。用户购买的冷水机组型号不同,温度要求不同,输入功率会有所变化,具体的输入功率大家可以参考压缩机厂家资料(东跃进常用的螺杆压缩机品牌是台湾汉钟、德国比泽尔)。

    耗电量则是指机组在设计工况下,单位时间的总用电量,单位为kw。

    三、冷冻水、冷却水流量

    这个是指机组在设计工况下,分别通过蒸发器、冷凝器的水流量,单位为m3/h。从蒸发器通过的水流量,我们称之为冷冻水流量;从冷凝器通过的水流量,我们称之为冷却水流量。螺杆式冷水机通常是选择壳管式蒸发器/冷凝器,对于有特殊要求的机组,也会选择采用不锈钢板式蒸发器(根据客户使用行业来具体选择)。

    四、水压降、制冷性能系数等

    螺杆式冷水机的主要技术参数表现在以上三部分,当然也还有我们比较耳熟的水压降,或是制冷性能系数等等。水压降是指机组在设计工况下,水流经蒸发器、冷凝器的压力损失,单位为mH2O;制冷性能系数是指制冷量与输入功率之比,W/W。

    螺杆式冷水机是工业制冷中最为常用的一款设备,由于制冷功率较大,因此常被用于油墨印刷厂、电池制造厂、混凝土搅拌站、化工厂、汽车制造厂、中央空调系统等大功率制冷需求场合。关于螺杆式冷水机使用中应注意事项,可持续关注东跃进。 螺杆式冷水机定做!欢迎关注无锡朝腾机械有限公司。

Main technical parameters of screw chiller

For all, laymen watch experts see road, in the field of mechanical industry, if you want a detailed understanding of the machine, the best is to understand the technical parameters of the industrial chiller is no exception, we are now a lot of people are beginning to use the screw type cold water machine, but we understand the screw chiller? Do you know its technical parameters? Xiao Bian will take you into Wuxi, Teng machinery, to understand the main parameters of industrial water chillers, a brief introduction:

Screw chiller

I. refrigerating capacity

It is an important technical parameter of screw chiller, and it can be related to the work efficiency of the whole unit. The refrigeration capacity mainly in refrigeration, which is under certain conditions, the chiller unit time from the object to be cooled absorbs heat, the unit kw/h, we will often use Kcal/h (1kw/h=860Kcal/h). The refrigerating capacity is decided by the type and the specification of the chiller. Therefore, if the user wants to meet his own refrigerating demand, he should choose the chiller according to the actual demand.

Two 、 input power and power consumption

For a screw chiller, the input power is the sum of the power of all the compressor shafts, kw. Users buy different type water chillers, temperature requirements are different, the input power will change, we can refer to the specific input power of the compressor manufacturers data (East Yuejin common screw compressor brand is Taiwan Hanbell, Germany Bitzer).

Power consumption refers to the total power consumption per unit time of unit under design conditions, and the unit is kw.

Three. Chilled water and cooling water flow

This refers to the unit in the design conditions, respectively, through the evaporator, condenser water flow, the unit is m3/h. The water flow through the evaporator, which we call the chilled water flow, is the flow of water through the condenser, which we call cooling water flow. Screw chillers usually choose shell tube evaporators / condensers, and stainless steel plate evaporators are chosen for special requirements.

Four, water pressure drop, coefficient of performance of refrigeration, etc.

The main technical parameters of screw chiller performance in the above three parts, of course, also we compare the familiar pressure drop, or coefficient of performance etc.. Hydraulic pressure drop refers to the pressure loss of the flow through the evaporator and condenser under the design condition. The unit is mH2O; the coefficient of performance is the ratio of the refrigerating capacity to the input power, W/W.

Screw chiller refrigeration industry is most commonly used in a refrigeration equipment, the power is larger, so it is usually used to ink printing factory, battery manufacturing plant, concrete mixing station, high power chemical plant, automobile factory, central air-conditioning refrigeration demand occasions. Attentions should be paid to screw chillers in the process of sustainable development.
