Recirculating Water Chiller-The Ultimate FAQ Guide by TopChiller

In laboratories and laser manufacturing units, machines like light microscopes and mass spectrophotometers are continuously running and they produce a huge heat load.

A Recirculating Water Chiller can be used to displace this heat through its cooling and HVAC function.

It is important to have precision and sharp temperature regulation for applications like laboratories, and laser industries to obtain accurate results and maximum output.

The Recirculating Water Chiller uses a stable supply of water and is very convenient to control the temperature in the most effective way.

Here is the complete guide about the Recirculating Water Chiller, its working principle, construction and maintenance, and a lot more.

What is a Recirculating Water Chiller?

A Recirculating water Chiller is a very efficient cooling assembly that is preferred for internal cooling applications.

It can provide excellent cooling for long hours and is frequently used in laboratories.

In laboratories, a Recirculating Water Chiller makes sure that the experimentation can be carried out under precisely controlled conditions and the working personnel is safe in the environment.

Due to the chemical reactions and the continuously running machinery, the temperature of the laboratory tends to rise.

A Recirculating Water Chiller is best for high heat loads. It works best at temperatures -130º and 302º Fahrenheit and comes with a built-in high-pressure pump.

What are the Main Components of a Recirculating Water Chiller?

Different components combine to form a Recirculating Water Chiller. These components include:

• Compressor:

The main function of the compressor is to create a pressure difference that will allow the movement of refrigerant.

It is always installed between the condenser and the evaporator. In most cases, the condenser is partly insulated and is attached to an electric motor which provides the driving force.

• Condenser:

Below the compressor and above the expansion valve lies the condenser. It works for removing heat from the refrigerant that is coming from the evaporator.

In a Recirculating Water Chiller, the condenser water is repeatedly cycled between the condenser and the cooling tower. With the help of this cycle, the temperature of the hot refrigerant coming from the compressor is lowered.

This is done by transferring the refrigerant heat to the condenser water from where it is sent to the cooling tower and removed.

Here an important thing to keep in mind is that a pipe wall separates the refrigerant and the water so that they do not mix.

On the inside of the pipe moves water while on the outside moves the refrigerant.

• Expansion valve:

The expansion valve is present between the evaporator and the condenser. The main function of this valve is to carry out refrigerant expansion which is followed by its pressure decrease and volume increase.

This helps the refrigerant to absorb the excess heat gathered in the evaporator.

• Evaporator:

Between the compressor and the expansion valve lies the evaporator. The evaporator works for gathering the excess heat from the industrial environment and sending it to the refrigerant from where it is passed to the cooling tower and removed.

As refrigerant takes this heat the temperature of the water drops. This chilled water is then used to keep the industrial area cool.

• Power unit:

It is optional to either directly attach the power unit with your Recirculating Water Chiller or to install it on the wall and build a powerful connection between them.

The power unit consists of a starter, speed controller, circuit breaker, and power monitoring equipment which help in controlling the overall power flow.

• Control Unit:

The control unit is adjusted according to industrial needs. It improves the performance and maintains the efficiency of the Recirculating Water Chiller.

The control unit also consists of alarms that help in the protection of the equipment and prevent damage to the Recirculating Water Chiller and also allow its remote monitoring and controlling.

• Water box:

The water box is installed on the condenser and helps in the direct fluid flow.

Another main role of the water box is to create a separation between the entrance and the exit allowing only controlled fluid flow through holes.

You can also cover these holes for redirecting the fluid flow.

Recirculating Water Chiller Sensors

How a Recirculating Water Chiller is better than an Air-Cooled Chiller?

A Recirculating Water Chiller is better than an Air-Cooled Chiller because of the following reasons;

• Stable performance

A Recirculating Water Chiller uses recycled water for its function and does not depend upon ambient air temperature.

Therefore, it is best to be used even if industrial and commercial air conditioning is required with fluctuating ambient temperature.

• Condenser

The presence of a water-cooled condenser that is connected to a cooling tower, in a Recirculating Water Chiller makes it efficient enough to work in the condition where there is just sufficient water supply.

• Size, Capacity, and Design

A Recirculating Water Chiller has a wide variety of sizes and capacities and you can choose the one that fits your needs and applications.

Mostly, Recycling Water Chillers are stationary but you can also get a portable one.

• Longer Lifespan

It is usually installed in an indoor setting and therefore it stays protected against rain, storms, sunlight, and other elements.

• Applications

A Recirculating Water Chiller is specially designed for moderate to large heat loads and therefore it can be used for bigger applications, whereas an air-cooled water chiller can only cater to small heat loads and it may collapse when put in a situation where it has to deal with increased load.

• Dependence on Ambient Air

A Recirculating water Chiller is independent of ambient air because it works by using water instead of air.

Also, you don’t need to invest in propeller fans to deal with the ambient air.

However, you might have to invest in a cooling tower but it is a one-time thing and it pays you off well.

• Indoor Installation

It is best for indoor installation and it also adds to the life of the laboratory Chiller since it remains protected.

You just have to establish a good water connection and you are good to go.

Air Cooled Chiller

How does a Recirculating Water Chiller Work?

To enhance the speed of the heat-removing process, a Recirculating Water Chiller uses the high-pressure flow and coolant circulation.

The four primary components take part in the working of Recirculating Water Chiller and these components are explained later in the text.

• The coolant is first fed into the compressor and is converted into a high-temperature and high-pressure gas.
• It is then moved to the condenser where it gives off its heat with the help of ambient air or water.
• Here, in the condenser, the gas is again converted into a liquid.
• In the next step, the refrigerant is run through the thermostatic expansion valve, and here, the temperature and the pressure of the refrigerant are decreased, which makes the fluid evaporate into a gas.
• Then this refrigerant in the gaseous form is again returned to the compressor and the process is repeated.
• No wastage of the refrigerant is seen in the case of a Recirculating Water Chiller as the refrigerant is recycled. Also, it recycles the water so there is no wastage of water as well.

What are the Applications of a Recirculating Water Chiller?

A Recirculating Water Chiller is specially designed to meet the requirements of high cooling loads such laboratories and laser industries, that too using the minimum quantity of refrigerant and water.

As a Recirculating Water Chiller works by circulating a fluid medium between +5 to +35 degrees Celsius, it is best for closed systems and the places where there is not an abundant supply of water.

• Laboratories

A Recirculating Water Chiller is ideal for laboratories and university research programs. Because of its decent design and appropriate size, it can be placed inside a laboratory to deal with the excess heat produced by the running machinery like the microscope, etc, and the heat produced by the reaction being carried out.

It is highly reliable to be used in a laboratory and also very convenient.

• Laser and Semiconductor Industries

The use of lasers itself produces a lot of heat and this heat must be removed to maintain an ideal environment in the industry.

Semiconductor industries also prefer a Recirculating Water Chiller because of its conventional design and effective operation. A Recycling Water Chiller is portable as well as stationary, so it can be used following the need.
