Water chiller is one of many systems available in the market for industrial cooling and other similar applications. It is a system consisting of many components that allows a refrigerant to travel from one component into another with the goal of generating chilled air to maintain a low level of temperature on any given space.
Find out what are the processes involved behind the operation of a water chiller. Most importantly, you will discover how the refrigeration cycle works and why it is an integral part of any chiller systems.
What Is Refrigeration Water Chiller System?
The refrigeration cycle is a critical component of a water chiller and its performance. It employs the principle of thermodynamics utilizing the concepts of heat of vaporization, pressure changes to a boiling liquid, the transfer of heat energy, and the absence of heat.
The process starts by using heat to turn liquid into a gas form. This is achieved only once a liquid reaches its boiling point – also known as evaporation. The next step involves manipulating the pressure of a refrigerant of a water chiller in order to start the refrigeration cycle. This process also eliminates heat from the refrigerant and dispersing it somewhere else.
All of the above processes result in the absence of heat in the refrigerant. This helps to produce the cooled effect that air conditioning and chiller systems are known to produce. When heat is removed, you can expect a cooler room.
What Is The Refrigeration Water chiller Principle?
The refrigeration process in a water chiller system is the most important processes involved to generate proper cooling. This process refers to the removal and relocation of heat from the refrigerant. In order to generate cool air, heat must be removed and then that heat is dissipated somewhere else.
In order to understand the refrigeration process of a water chiller, it is important to take a closer look into the working principle behind it. It starts with the method of measuring heat, which is known as the British Thermal Unit (BTU). This unit of measurement refers to the amount of heat needed to transfer heat onto a medium, such as a liquid refrigerant. This is also the standard of measurement in the cooling industry.
The BTU concept applies for boiling water, which must be 212 degrees Celsius to reach boiling point. It won’t reach anywhere beyond that; instead, water transforms into vapor. This process is known as the Latent Heat of Evaporization. Therefore, this is what happens during the refrigeration process of a water chiller refrigerant. The application of pressure to the air molecules enables the liquid state to turn into gas.
In order to facilitate the process described above, a water chiller is made up of several components. Each of these components performs a cycle of removing and relocating heat from a refrigerant to produce a cooling effect.
What Is Air-Cooled Refrigeration?
Air-cooled refrigeration is one of many types of water chiller types. It works by absorbing heat from the process water before the excess heat is transferred back to the surrounding air. It is commonly used wherever the excess heat that is discharged is not a factor.
This type of refrigeration unit requires less maintenance than other types of water chiller refrigeration. It also does not require the use of a cooling tower and uses up to 10% less power than water-cooled chiller.
What Is Water-Cooled Refrigeration?
Another example of a water chiller refrigeration process is one that is water-cooled. This type of chiller absorbs heat from the process water and then transfers it to a cooling tower (or a separate water source). This is designed for large cooling capacities or in situations wherein the use of an air-cooled chiller system would prove difficult or impossible.
A condenser water treatment is needed for this type of water chiller in order to prevent the buildup of minerals. When there is too much mineral deposit, it can result to poor heat transfer that eventually lowers the efficiency of the unit.
What Are The Types Of Water Chiller System?
There are two types of refrigeration for a water chiller: vapor compression and absorption.
The vapor compression cycle involves passing the refrigerant through four major components: evaporator, compressor, condenser, and expansion valve. The absorption cycle requires the refrigerant to go through five main components: solution pump, condenser, evaporator, generator, and absorber.
What Is A Vapor Compression Chiller System?
The vapor compression cycle involves processing the refrigerant by flowing through the four main components of the water chiller. It starts off with the low pressure liquid refrigerant passing through evaporator wherein it absorbs heat and transforms into vapor form. From there, it enters the compressor and the low pressure vapor is changed into a high pressure one.
Once the high pressure vapor exits the compressor, it goes to the condenser wherein it is cooled. Once cooled, it releases any excess heat and passed on to the expansion device. From there, it repeats the same process to generate a consistent cooled air with the water chiller.
What Is An Absorption Chiller System?
The absorption cycle is the next type of refrigeration cycle commonly employed in a water chiller. It has different components than a vapor compression cycle: evaporator, condenser, generator, and absorber. It also comes with a solution pump.
The solution pump is where the lithium bromide is collected while in its diluted form. It is transferred through a shell and into a tube heat exchanger. From there, the diluted solution enters the generator before being passed onto the condenser. The heat is removed with the help of the cooling water and then moves to the evaporator. The refrigerant liquid is boiled to achieve the refrigerant effect. The final process is when the refrigerant vapor is passed onto the absorber.
What Refrigerants Are Commonly Used In Water chiller?
There are many types of refrigerants used in a water chiller. The type of refrigerant used will be determined by the required cooling temperature for a given application. One of the most common types of refrigerants used in commercial and residential chillers are CFCs, or more commonly known as Freons.
To choose the right refrigerant, it is important to check the Ozone Depletion Potential (ODP) and the Global Warming Potential (GWP). Other factors to consider when choosing a refrigerant for a water chiller include the type of compressor, design of compressor, required cooling, load requirement, maintenance, and availability of facilities like water or power.
Aside from CFC, the other types of refrigerants used for a water chiller include R11, R12, R502, R21, and R22.
What Are The Types Of Chiller Based On Driving Force Of Refrigeration?
There are two types of chiller based on the driving force for refrigeration: mechanical compressor chiller and absorption chiller.
The mechanical compressor chiller is a type of water chiller that relies on a compressor to boost the pressure of the refrigerant. Under this type of chiller are many other sub-categories. These sub-categories of chillers that are equipped with a compressor make them suited for a variety of industrial applications.
The absorption chiller is any type of water chiller that employs heat-driven concentration that enables the refrigerant vapors to be transported from one component to another. Water is the most common type of refrigerant used.
What Is Mechanical Compression Chiller?
A mechanical compression chiller relies on the use of a compressor in order to facilitate the movement of the refrigerant through various components. It is also responsible for increasing the pressure and temperature of the refrigerant to make it suitable for cooling a given space.
There are many types of mechanical compression water chiller in the market. It is important to know the difference in order to choose the most appropriate one to use. They are classified based on the compression type.
The reciprocating chiller works in the same way as a car engine, which is also why it is also called as the piston-type compressor. It is composed of multiple pistons that are powered by an electric motor. This action enables the pistons to compress the gas to heat it before it is discharged to the condenser. It goes through an unloading process that will enable a single compressor to produce a wide range of capacities that match the system’s load.
The rotary type compressor is another type of mechanical compression water chiller. It is made up of a helical or screw-type compressor. These two rotors move but they never come into contact with each other (unlike the piston-type). It can produce a capacity of up to 450 tons.
The centrifugal is the third type of mechanical compression water chiller. This one comes with a compact design with high cooling capacity. It is made up of inlet vanes and valves that enable it to control the chilled water capacity. It can generate more than 150 tons for various applications.
The frictionless centrifugal is the last type of mechanical compression water chiller. It is also the most energy-efficient that uses magnetic bearing technology. It does not require the use of a lubricant and can generate up to 300 tons in capacity.
What Is Absorption Chiller?
An absorption chiller is the second type of water chiller based on the driving force behind its refrigeration. It uses a heat-driven concentration in order to push the refrigerant to move from one component to another.
It starts off by diluting the refrigerant before heat is introduced in order to increase its concentration. There are different types of absorbent and refrigerants used for commercial chiller applications. For smaller applications of water chiller, ammonia is the common type of refrigerant. Lithium bromide is the top choice for absorbent because it is non-toxic and relatively inexpensive.
There are two general types of absorption chillers in the market. The single effect units employ low-pressure gas to drive the refrigerant. The double effect units are gas-fired or utilize high-pressure steam.
How Do You Select Industrial Water chiller?
Choosing the right industrial water chiller is more complex than it seems. The most important factor for choosing is the size of the chiller. The size must be appropriate for the intended use to ensure that it can generate enough cooling for the desired operation.
Otherwise, it is not only lacking in energy efficiency.
But it can affect the industrial processes that require cooling.
If you do not choose the right size of industrial water chiller, this could mean more power is required for the system to operate and maintain the cooling temperature.
Can You Use Water Chiller In HVAC Systems?
There are many uses and applications for a water chiller. Yes, it can be used for air conditioning units and other forms of HVAC systems.
There are also many other applications for the water chiller across numerous industries. One of its most common applications is for cooling in the plastic industry. The process of cooling plastic after injection molding is highly important as it makes the resulting product very sturdy and durable. It is also beneficial in cooling the equipment used for the manufacture of plastic since they generate a lot of heat.
The use of water chiller is also common in the plastic industry.
As well as in the use of high-powered electric equipment for medical use.
It is essential to achieve proper cooling in diagnostic tools and equipment such as MRI and PET, to name a few.
Safe Operation Regulations of Industrial Water Chiller
Precautions for Air Water Chillers installation:
Please choose a stable foundation before installing the air-cooled chiller.
The surrounding air is unblocked, the air is pollution-free, and the place with little oil
The canopy should be more than 1.5 meters above the machine platform,
If you still find the surrounding air is muggy during use,
Please install an exhaust fan to maintain air convection,
Or exhaust the hot air to the outside with an exhaust pipe,
This will not only increase the service life of the ice water machine,
And can improve efficiency and reduce costs.
The ambient temperature during installation is preferably below 35℃,
Ensure that the machine is effective.
The power supply, load, and grounding parts shall be constructed in accordance with relevant laws and regulations.
The first operation must check the following items are correct:
- Whether the power supply voltage and a number of phases meet the model specifications, please refer to the nameplate.
Note that the power supply of chillers above 3HP is three-phase, voltage 380-415V,
The 50HZ power phase is R.S.T, the neutral line (zero line) N, and the ground line is E.
- Whether the make-up water inlet has been connected to the pipeline, and the water source must not be shut off
- Fill the ice water tank with water before starting the water pump.
- Please pay attention to whether the water pump and fan motor are running in the reverse direction.
If it is reversed, any two of the power bit lines must be exchanged, and then closed again.
- Turn on the water pump switch. At this time, please note that the ball valve at the inlet and outlet of the chilled water must be opened.
- Finally, turn on the compressor switch, the compressor and fan will run automatically,
Please check and adjust the required temperature.
- When shutting down, please shut down in the reverse order.
