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：
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:
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.
