People often ask about the problem of cooling and cooling in the chemical fiber industry, and what is the good problem of water cooling. Let's discuss it with everyone. The following discussion is based on practical experience. (Considering that the number of air-cooled condensers of large refrigeration units is too large, it is usually difficult to arrange. On the other hand, too small water-cooled refrigeration units are also unfavorable for use, so for medium air-cooled units and the same water-cooled refrigeration units. Compare.)
Jincheng Chemical Fiber Industry Refrigeration Air Cooling Module Chiller
The chemical fiber industry refrigeration air-cooling module cold water system is composed of outdoor units, end devices in each room (fan coils and ducts, etc.), water pipe systems, circulating water pumps, etc. The chilled water is sent to different areas through circulating water pumps to connect different forms. The end device sends hot and cold air through the end device and the pipeline to adjust the indoor temperature, and each fan coil can be independently controlled.
Jincheng Chemical Fiber Industry Refrigeration Water Cooling Screw Type Chiller
Chemical fiber industry refrigeration water-cooled screw type chiller is a traditional air conditioning system with water as cooling medium. It is composed of cooling tower, water-cooled screw unit, indoor end device (including fan coil and air handler), air duct system and water pipeline. System, circulating water pump set and other components. Compared with the same cold air-cooled unit, the condenser and the evaporator are made of special high-efficiency heat transfer tubes, which are compact, small in size and high in efficiency, and are suitable for central air conditioning systems and process chilled water systems.
Common advantages of chemical fiber cooling and air cooling in chemical fiber industry
The chemical fiber industry refrigeration air-cooled chilled water system and the water-cooled screw system have the following advantages:
First, save investment
Because the refrigeration and heating conversion and the operating principle are the same, the water is used as the brine to transport the cold heat to the room. The construction and equipment and materials are very low. The same system can be used for both cooling and heating. Heating facilities save initial investment.
Second, a wide range of applications
It is especially suitable for air-conditioned occasions such as villas, hotels, hospitals, office buildings, entertainment venues, restaurants, supermarkets, etc.
Third, flexible layout
Different types of indoor units can be selected to meet the indoor requirements of different decorative styles; when the decoration pattern changes, air conditioners can be configured according to different decoration patterns.
Comparison of refrigeration air cooling and water cooling systems in chemical fiber industry
First, the system structure
The chemical fiber industry refrigeration air-cooled unit adopts air cooling mode (fan cooling);
The chemical fiber industry refrigeration water cooling unit adopts cooling water cooling mode, and the water pump plus cooling tower and circulation pipeline cool down the unit.
Therefore, the air-cooled unit only needs an air-cooled condenser or a fan. Water-cooled chillers need to be equipped with cooling towers, pumps and circulation lines. Water cooling from the structure is more complicated than air cooling.
Second, the scope of application
The chemical fiber industry refrigeration air-cooled refrigeration unit is suitable for areas where the water source is located in a tight area. The longer the annual operating hours, the more favorable the air-cooled refrigeration unit is.
The annual comprehensive cost of the chemical fiber refrigeration refrigeration air-cooled refrigeration unit is lower than that of the water cooling system. However, if the water cooling system is managed and the water supply is controlled below 3%, the annual cost of the water-cooled unit is lower than that of the air-cooled system.
The chemical fiber industry refrigeration air-cooled chiller adopts air cooling mode, which eliminates the cooling tower, cooling water pump and pipeline system that are essential for the cooling water system, avoids condensation of the condenser, blockage of water pipes, and saves water in areas with poor water quality. Resources are the economical and simple models for maintenance and repair in current refrigeration equipment products.
Third, from the perspective of cold
For example, 20HP Bitzer medium and high temperature compressor 4NCS20.2, when the evaporation temperature is 0 degrees, the condensation temperature is 50 degrees, it is 38.6KW cooling capacity, the power is 13.65KW, while the water cooling is 44.5KW, the power is 12.1KW in the same working condition. .
It is slightly better than the air-cooled unit in terms of cooling capacity and power consumption. However, the power of the water cooling pump power cooling tower fan has not been added to the calculation.
Chemical fiber industry refrigeration water cooling system Disadvantages: Since the cooling water absorbs heat, it is in contact with air, CO2 escapes into the air, and the dissolved oxygen and turbidity in the water increase, causing four major problems in the cooling circulating water system: corrosion, scaling, and algae breeding. And sludge. If the water quality is not treated, the refrigeration equipment will be seriously damaged, and the heat exchange efficiency will be greatly reduced, resulting in waste of energy. Therefore, it is very important to carry out corrosion inhibition, scale inhibition, sterilization and algae treatment on the system water.
Disadvantages of refrigeration and air-cooling systems in chemical fiber industry: The power consumption per unit of refrigeration capacity of air-cooled refrigeration units is slightly higher than that of water-cooled units, but the annual comprehensive cost of air-cooled units is basically the same as that of water-cooled units. The results of technical and economic analysis show that it is reasonable to configure air-cooled condensers for medium and small refrigeration units. The longer the annual operating time of the refrigeration unit, the more favorable it is to adopt air-cooled condensation.
According to the research results of the research institute's research on the economics of air-cooled and water-cooled systems, the results show that:
Through the evaluation of the test, the water-cooled condenser refrigeration system is superior in the cooling medium with excellent heat transfer performance of the condenser. The water-cooled condenser refrigeration system has a large cooling capacity coefficient.
Air-cooled condensers are the easiest to operate and maintain, and have low equipment investment. They are suitable for use in areas where water resources are scarce.
The water-cooled condenser is suitable for applications where the condensing load is high and the ambient temperature is high.
For applications:
The chemical fiber industry refrigeration water cooling is suitable for medium and small systems, and one tower can be used for multiple machines.
The chemical fiber industry refrigeration air cooling is applied to small and medium-sized units, a condenser and one unit.
