Introduction of water-cooled chillers.
The water-cooled chiller perfectly combines the advantages of high reliability, high efficiency, and high automation.
It is a more convenient and reliable air-conditioning host.
This product is widely used in shopping malls, hotels, theaters, hospitals, large factories, and high-rise buildings, and other occasions that require air conditioning.
Important features of the water cooled chiller
Water cooled chiller classification
According to different compressors, it is divided into two categories:
Water-cooled screw chiller
water-cooled reciprocating chiller
The water cooled chiller specifications are complete, and customers have a lot of room for choice
1. The cold water produced by the water-cooled unit is sent to the client through the refrigeration pump, exchanged with the cold water with a higher temperature, and returned to the chiller.
2. Then the heat of the high-temperature chilled water is transferred to the low-temperature cooling water through the chiller, and the cooling water becomes the high-temperature cooling water.
3. The high-temperature cooling water is sent to the cooling tower through the cooling pump, and the heat is discharged to the outdoors through the cooling tower, turning into low-temperature cooling water and returning to the chiller.
Start sequence of water-cooled chiller system
Open the cooling and freezing pumps water inlet and outlet valves
Open the chiller water inlet and outlet valves
Open the cooling tower water inlet and outlet valves
Start the cooling tower
Start the cooling pump
Start the refrigeration pump
Start the chiller
The reason for opening the inlet and outlet valves of the main engine, cooling pump, refrigeration pump, and cooling tower first
The refrigeration of the water-cooled chiller system is mainly transmitted by water
Water is transported by pumps and pipes
Therefore, before the water pump is started, the valve should be opened first to ensure the smoothness of the pipeline.
If the pipeline is blocked, once the water pump starts. The pipe will burst under huge water pressure
Turn on the cooling tower again, turn on the cooling pump, turn on the refrigeration pump, and turn on the water-cooled chiller.
1. The cooling tower must ensure that the cooling water can dissipate normally
2. The cooling pump must ensure that it can circulate and absorb the heat conducted by the chiller
3. The refrigeration pump must ensure normal circulation and release heat through the chiller
Water-cooled chiller system refrigeration system stop sequence
Stop the chiller host
Stop the refrigeration pump
Stop the cooling pump
Stop the cooling tower
Close the cooling pump and the water inlet and outlet valves of the refrigeration pump
Close the inlet and outlet valves of the chiller host

Comparison of water-cooled screw unit and lithium bromide unit
1. The advantages of water-cooled screw chillers
Water-cooled screw chiller is a kind of refrigeration unit that uses water as the cold source (exhaust heat source). The compressor is screw type. It has two water systems, namely the chilled water system to the air-conditioning room; and the cooling water for heat rejection System, the cooling water system is equipped with a cooling tower or uses ground water.
Features of this unit:
1. It can only be used as a single cooling machine, not heating. Boiler or urban heating network must be used for heating in winter
2. Small size, large capacity, compact structure, smaller than a lithium bromide unit with the same capacity.
3. The high efficiency ratio is generally 4.4, and the highest can reach 4.8, which is significant in energy saving.
4. It can automatically adjust the output corresponding cooling capacity according to the heat load of the air conditioner. There are 25%, 50%, 75%, 100% stepless energy adjustment and 0~100% stepless energy adjustment. Significant energy saving, avoiding energy waste.
5. The compressors used in water-cooled screw chillers are produced by world-renowned manufacturers Taiwan Fusheng and Taiwan Hanbell. Four-way reversing valve, expansion valve, solenoid valve, check valve, stop valve, sight glass and other valve parts are also produced by world-renowned manufacturers, such as American Aike Company, Japan Saginomiya Company, Danfoss Company of Denmark, etc. The unit is of high quality, reliable performance, and a life span of 15 to 20 years.
6. Fully automated, computer controlled, no need for human supervision.
It is widely used in summer air conditioning of large buildings such as office buildings, hotels, restaurants, hospitals, schools, dance halls, theaters, residential buildings, shopping malls, etc. The water-cooled screw chiller produced by our company has 11 specifications, with a capacity of 110~3200KW, and a single unit can supply 1300~8000 m2 of building air conditioning. Multi-functions can be used for air conditioning in buildings of tens of thousands of square meters.
The characteristics of lithium bromide unit
1. The service life and cooling capacity attenuation of the unit
Lithium bromide chillers have high vacuum requirements, but limited to the current technological level of some companies, it is difficult to maintain a high vacuum for a long time.
According to relevant information, for a unit of 100×104kcal/h, if 20 grams of air leaks in, the unit cannot be cooled.
In actual projects, there have been instances where refrigeration cannot be performed for the first time in official operation.
In the presence of air, the lithium bromide aqueous solution is very corrosive to the materials used in the manufacture of lithium bromide units, such as carbon steel, copper and other metals. If the vacuum of the unit is not well guaranteed, the unit will soon be scrapped.
The life of lithium bromide units produced by general manufacturers is only about 10 years without reliable materials and technical guarantees.
Due to corrosion, fouling, blockage, reduced vacuum and other reasons, the cooling capacity of lithium bromide units has a large attenuation.
The units produced by manufacturers with general conditions have the problem of cooling capacity attenuation, and some cooling capacity attenuation reaches 15-20% per year.
Some manufacturers, due to the use of some special technical processing, and the sample calibration value is lower than the maximum refrigeration capacity of the refrigerator, so that the actual cooling capacity attenuation during operation is not significant.
There are also individual manufacturers who claim to have no cooling capacity attenuation, which should be the goal and guarantee for unit production in the future.
For the problem of cooling capacity attenuation, engineering designers must make correct judgments after site inspection and in-depth understanding, and include them in the selection calculation, otherwise problems will occur during long-term operation.
Although the air-conditioning load of some projects is too large or too large to cover up the seriousness of this problem, you should keep a clear understanding of each account.
2. Energy consumption and power consumption of the unit
Since the lithium bromide chiller achieves the purpose of cooling at the expense of heat energy, its power consumption is very small (only about 2% of the compression type), but its heat consumption per unit of cooling capacity is large, that is, its refrigeration coefficient Smaller, the current domestic maximum value is only about 1.2, while the compressor unit is above 3.5.
Therefore, the lithium bromide unit only uses less electricity and cannot save energy.
Therefore, the best use conditions for this unit are occasions with waste heat, waste heat or power shortage areas, and its development cannot replace compression refrigeration, but can only be developed accordingly.
Chilled water outlet temperature in practical applications, the level of chilled water temperature affects the determination of air-conditioning methods, the layout of air-conditioning systems, and the selection and calculation of air-conditioning equipment.
Most of the air-conditioning equipment information we usually encounter is based on the supply and return water temperature of 7/12℃.
If the chilled water prepared by the lithium bromide chiller in the actual project is 10/15℃, the cooling capacity of each air conditioning equipment and the final state point of air treatment must be rechecked and calculated.
For some engineering designs, since the main air-conditioning and refrigerating machine room are not designed by the same unit, and the main body is followed by the machine room, the above situation may occur at this time.
If the outlet water temperature of the chiller does not meet the main design requirements, the main air conditioner cannot be guaranteed.
