How Does a Water Cooled Chiller System Work?

How does a water cooled chiller work?

water cooled chiller system uses water and the refrigeration cycle to achieve cooling.

In other words, it helps to cool your machines or room.

How a typical GesonChiller water cooled chiller system working principle.

The cooling process cools down the water from the evaporator, once the refrigerant gets to the important part of the refrigeration cycle.

Then, a pumping machine will circulate it from the chiller system to the process.

Because the water is cool, it will absorb heat from the process and become warm, then it returns to the chiller.

So the water is the secondary refrigerant, water cooled chiller systems remove heat from processes or rooms, achieving cooling.

1. Air-cooled chiller

The medium of heat exchange is air, which uses special fans for chillers and variable-frequency axial fans, so it is called air-cooled

2. Water-cooled chiller

The use of water to exchange heat requires the installation of a special cooling tower for the chiller. The source is water, and the special cooling tower is equipped, so it is called “water cooling”.

Two, the design principle is different

1. Air-cooled chiller

The air-cooled machine takes away heat through the flow of air,
and the air through the condensing coil to take away the heat,
and the refrigerant inside the machine is cooled.

2. Water-cooled chiller

Through the cooling water circulation of the water cooling tower,
the heating is taken away,
then the chilled water is chilled.

Three, the installation method is different

1. Air-cooled chiller

The role and requirements of cooling towers and cooling pumps

1. The high-temperature cooling water from the water-cooled chiller, the cooling pump sends the high-temperature cooling water from the chiller to the cooling water tower
2. The cooling tower returns to the chiller after cooling the cooling water
3. The pressure difference between the cooling water inlet and the cooling water return water is about 3-4kg.

The role and requirements of the refrigeration pump.

1. The role of the refrigerating pump is to deliver low-temperature chilled water to the client, and then return to the chiller after the heat is exchanged
2. The pressure difference between inlet and return water is about 3-4kg

The role and requirements of the water-cooled chiller.

• 1. Function: absorb the heat of high-temperature chilled water and transfer it to low-temperature chilled water
• 2. The temperature difference between freezing and cooling water is 4-6 degrees Celsius

Principle of the water-cooled chiller system.

• 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

1. Open the cooling and freezing pumps water inlet and outlet valves
2. Open the chiller water inlet and outlet valves
3. Open the cooling tower water inlet and outlet valves
4. Start the cooling tower
5. Start the cooling pump
6. Start the refrigeration pump
7. Start the chiller

The reason for opening the inlet and outlet valves of the main engine, cooling pump, refrigeration pump, and cooling tower first

1. The refrigeration of the water-cooled chiller system is mainly transmitted by water
2. Water is transported by pumps and pipes
3. Therefore, before the water pump is started, the valve should be opened first to ensure the smoothness of the pipeline.
4. 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

1. Stop the chiller host
2. Stop the refrigeration pump
3. Stop the cooling pump
4. Stop the cooling tower
5. Close the cooling pump and the water inlet and outlet valves of the refrigeration pump
6. Close the inlet and outlet valves of the chiller host
7. Close the water inlet and outlet valves of the cooling tower

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~KW, and a single unit can supply ~ 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.

This makes it lighter and ideal for use on a sealed compartment.

Are There Any Drawbacks to a Screw Chiller?

While there are plenty of advantages that you can get with the use of a screw compressor chiller, there are also a few things you need to be on the lookout for. Given the benefits that you can get, expect to pay a higher price for this type of chiller. It is more expensive than a piston compressor operation since the parts are more expensive.

What Need to Care of Screw Water Chiller System?

Another downside to the use of a screw type chiller is that it requires higher lubricant consumption. Its use of a complicated lubricating system enables it to endure for many years even with regular use. At the same time, the installation process is quite complicated. You need to hire someone who is an expert with this type of chiller to do the installation.

What Types of Screw Chillers?

There are two types of screw chillers: air cooled screw chiller and water cooled chillers. In order to understand how this type of chiller works, it is important to look closely into each type.

The water cooled screw chiller uses water in order to generate the cooling effect. The screw compressor takes the low temperature refrigerant in the evaporator and directs it into the cylinder until it goes through the compressor steam. The refrigerant passes through the condenser and into the exhaust pipe wherein it exchanges heat with the cooling water. It goes through another process that condenses the refrigerant gas into a high pressure liquid. It goes through several more processes of continuous circulation until the cooling of water is achieved.

How Does It Work?

The next type is the air cooled screw chiller that consists of the semi-hermetic screw type compressor as its primary component. The working principle of this unit starts with the compressor and then moves to the condenser and evaporator before it goes through expansion valve. From there, it enters the dry filter and passes through the pump.

What Are The Different Types of Chillers?

In general, there are two types of chillers available in the market,

The screw type chiller and the piston chiller. These two types of compressors are designed to convert a power source into stored energy consumption through compressed air. Choosing between the rotary screw and piston type compressor will depend on your needs and the purpose for using the system.

What is Piston Type Chillers?

The piston type or reciprocating chiller involves the movement of pistons in a downward motion. The up and down motion of bringing gas into the system is the reason why it is called a reciprocating motion. It has plenty of moving parts such as the piston, crankshaft, piston ring, valves, connecting rods, and more. Due to the number of parts, it is very prone to breaking down, especially when one of these parts are not in proper placement or are not functioning properly. This is one of the reasons why many industries have done away with the piston type chiller since it is not very reliable. At the same time, it is also very large in size so you need a separated compressor compartment, which also helps to reduce noise and vibration.

The second type of chiller is known as screw type chiller. It utilizes a rotary compressor, which is also known as a roller. Unlike the piston type chiller, the rollers sit off-center so that one of them comes into contact with the wall. This movement mimics the function of the reciprocating compressor, which allows gas to come in and out. The basic principle of the two moving parts is that they move towards the opposite direction so that air can be drawn in between.

Scroll chillers start at 20 tons and go up to 200 tons in size. It is important to understand that screw chillers only have one compressor used for cooling, so if this goes down then the entire capacity of the chiller would be lost.A screw chiller has excellent full-load and part-load power/ton efficiencies.

What is the difference between screw chiller and centrifugal chiller?

Centrifugal compressors have improved full load efficiency, but screw compressors are not far behind. They’re also comparable in part load efficiency. And in part-load applications, they’re better because they’re stable down to 10% capacity, where centrifugal compressors can start to produce surges at 20% up to 40%.

What Features To Look For in Air Cooled Screw Chiller?

When investing in air cooled screw chiller, there are a few features to look for. The first one is the high-efficiency compressor. This is vital as it ensures stable operation, the efficiency of cooling performance, and the ability to save energy consumption.

Another feature to look for is the frosting method. It optimizes the defrost cycle so as to ensure that the unit can perform optimally at all times. Other features to take into account include the motor cooling unit and the heat exchange tubes. The latter is particularly important because a sealed and reliable tube can increase efficiency by 5%.

What Is The Four Pre-cooling Processes For Poultry Chicken Slaughter？

Poultry chicken slaughter will enter the pre-cooling stage after passing through processes such as stunning, feathering, wax immersion, and evisceration. The main purpose of pre-cooling is to cool the carcass, so as to ensure the quality of the products after processing and leaving the factory. The specific operation is to place the carcass in a low temperature environment of 0~5°C for a period of time to reduce its temperature to below 8°C. At present, the most commonly used pre-cooling methods mainly include air cooling, water cooled, wet cooling and spray cooling.

1 The air cooled Screw Chiller For Chicken Processing type uses air circulation to cool the carcass, which is a more economical pre-cooling method with early investment. The disadvantage is that the gas circulation will not only take away part of the heat, but also take away a lot of water. The carcass is in an air-dried environment, which has a greater impact on the quality of poultry meat.
　　
2 The water cooled Screw Chiller For Chicken Processing type is to put the chicken and poultry body in cold water for cooling, which in a certain sense makes up for the shortcomings of the air cooled screw chiller type. But its disadvantage is that the pre-cooling process consumes a lot of water and is relatively poor in energy consumption saving; the carcass is soaked in water for too long, which will affect the texture and taste of the meat and reduce the quality of the meat.

　　
3 The wet cooled method uses damp and cold air to cool the carcass. This method has a better cooling effect and has little effect on the meat. It is suitable for the cooling process of fresh products, but the initial investment cost is higher.
　　
4 The spray cooling type combines the advantages of air cooling and water cooled. It can maintain the moisture content of the carcass surface in a normal state without affecting the meat. It also has excellent performance in energy consumption saving and consumption reduction, and it can shorten the cooling time. The pre-cooling method is widely used.

What is Load Cooling Capacity?

Load cooling capacity is the amount of heat that a chiller can remove from the building’s mechanical room.

How Screw Chillers Improve Capacity

Screw chillers are the most efficient way to chill water in an industrial or commercial setting. They can be used to take the temperature of water down to 4°C (39°F) for cooling purposes. The water is pressurized and forced through a rotating screw inside of a closed chamber where it goes through an evaporative process. This process creates cold temperatures for this process, which in turn produces chilled or cold water.

The deliver optimal efficiency of screw chiller comes from its ability to self-trim when running at high-pressure. When the pressure is high, the amount of heat that is lost will decrease due to reduced friction between the screw and pipe wall when rotating at high speeds.
