CDU cold quantity distributes unit: CDU cold quantity allocates unit type selecting and pipeline design point
In system of industrial automation control, CDU cold quantity allocates unit to acting crucial role. CDU, namely cold quantity distributes unit, the cold quantity in basically be being used at adjust and controlling refrigeration system allocates. The type selecting that the article will distribute unit around CDU cold quantity and pipeline design point spread out thorough analysis, with period the reference that provides major for the reader.
One, CDU cold quantity allocates unit type selecting point
1.Decide refrigerating capacity according to systematic demand
CDU cold quantity allocates unit type selecting to want to decide refrigerating capacity according to effective demand of the system above all. Generally speaking, refrigerating capacity needs to satisfy the requirement that the system moves, consider certain redundant coefficient, in order to ensure the system moves normally in height period of time.
2.Consider equipment dimension and installation space
CDU cold quantity allocates unit type selecting to still need to consider equipment dimension and installation space. Equipment dimension should with spot condition conform to, facilitating installation and safeguard.
3.Choose right refrigeration dose and compressor
The choice of refrigeration agent and compressor affects CDU cold quantity to allocate unit function and energy-saving effect directly. Should mix according to systematic characteristic moving environment, choose right refrigeration dose and compressor.
4.Notice the function index of equipment
In the type selecting process that in CDU cold quantity distributes unit, still need to pay close attention to the function index of equipment, be like effect comparing, noise, can oscillatory etc. Function shows the equipment of elevation can provide more high grade experience for the user.
5.Consider the price of equipment and after service
The price and after service are the main factor that CDU cold quantity assigns unit type selecting. Below the premise that assures equipment performance, as far as possible alternative price compares expensive product, pay close attention to the after service of the manufacturer.
2, the pipeline that CDU cold quantity distributes unit designs a point
1.Layout of sound program pipeline
CDU cold quantity allocates unit pipeline design to want overall arrangement of sound program pipeline above all, ensure the system moves smooth. Pipeline layout should as far as possible concise, intuitionistic, prevent across and collision.
2.Choose right tubal capable person and join way
Tubal material and join means allocate unit function and security to have main effect to CDU cold quantity. Should mix according to systematic characteristic requirement, choose right tubal capable person and join way. Commonly used canal material has copper pipe, aluminous canal, stainless steel canal to wait.
3.Consider pipeline pressure loss
Pipeline pressure loss is the crucial factor that affects systematic performance. In designing a process, want loss of mature pipeline pressure, ensure the system moves normally.
4.The setting expands reasonably cistern and pressure watch
Expand cistern and pressure watch are the important fittings that CDU cold quantity distributes unit. The setting expands reasonably cistern and pressure watch, conduce to the stability that improves a system and security.
5.Prevent leak and pollution
When design CDU cold quantity allocates unit pipeline, want to take effective measures to prevent leak and pollution. If use the data such as fluid sealant, spacer, ensure pipeline connective dependability.
3, summary
CDU cold quantity allocates unit to have important place in system of industrial automation control. The type selecting that distributes unit through cold to CDU quantity and pipeline design point undertake an analysis, conduce to increase systematic performance and stability. In type selecting and design process, need to consider the factor such as space of performance of systematic demand, equipment, installation integratedly, ensure CDU cold quantity allocates unit to produce a result in applying actually.
