What is a Glycol Chiller System?

A Glycol Chiller System is a well-designed refrigeration system and sometimes it uses antifreeze for low-temperature cooling requiring applications that provide a cooling device having a constant current, constant temperature, and constant pressure.

A Glycol Chiller System has an internal water tank that keeps the injected water.

The already running refrigeration system cools the injected water. The chilled water is then sent to the application to be cooled by using a circulating water pump.

When the cooled water reaches the application, it removes all the heat from the system and absorbs itself.

The hot water is then sent again to the water tank of a glycol chiller machine.

The regular water chiller uses water as cooling media to cool down the equipment.

But Glycol Chiller System uses a mixture of water and water-miscible chemical compound (Glycol) as a heat transfer medium.

Two types of glycols can be used as a cooling medium in a Glycol Chiller System.

These are ethylene glycol and propylene glycol. They can be used when mixed in the water to maintain the temperature even below zero degrees.

What are the Working Principles of the Glycol Chiller System?

A Glycol Chiller System is used in different industrial sectors to provide coolant to the products machinery, mechanisms, etc. It uses a mixture of water and glycol in the process.

A refrigeration system of this type removes the heat from the process using fluids as a heat transfer medium. A Glycol Chiller System processes the water and obtains heat from the system and ejects the heat into the air with the help of a heat exchanger.

The working of a Glycol Chiller System is mostly the same as of other industrial chiller systems. It uses for basic components to execute the mechanical cycle through which the refrigerant passes.

The process starts with the evaporator. The evaporator of a Glycol Chiller System evaporates the refrigerant that is flowing over the evaporator tube bundle.

During this process, the process water is continuously in a cycle through the bundle. The mixture of glycol and water absorbs the heat.

So, the process mixture of glycol and water cooldowns your application before it returns to the process again. On the other side, the vapor produced by the evaporator is pulled to the compressor.

The compressor compresses the refrigerant and increases the pressure and temperature.

Then this high-pressure refrigerant is sent to the condenser. The condenser of a Glycol Chiller System removes the heat of the refrigerant by using glycol.

The condenser condenses the refrigerant vapor into the liquid form and then transfers this liquid to the expansion valve.

The expansion valve then decreases its pressure and the small amount of refrigerant boil into the air, and the remaining refrigerant becomes cooler to attain the desired temperature.

All the above cycle repeats continuously according to the requirement of your application.

How to Determine the Capacity of your Glycol Chiller System?

You can calculate the capacity of a Glycol Chiller System by using the information required by this guide.

The capacity of the Glycol Chiller System depends on different factors and calculations like volume, mass, time, etc.

When you’re going to have an energy-efficient and inexpensive coolant for your Application .it is necessary to be guided completely.

The capacity of a Glycol Chiller System mainly depends on its ability to dissipate heat or the total amount of work done by it.

Here is a simple formula to measure the heat load capacity of a Glycol Chiller System for your application.

There is no need to be an expert. Anyone can easily calculate these values to find accurate results.

The following calculations are needed to calculate the capacity of a Glycol Chiller System.

• You need to measure the flow rate of coolant being processed in Gallons per minute (GMP)
• Second, calculate the temperature differential of the process coolant.

The flow rate can be measured by using a flow meter and temperature differential can be easily measured by subtracting the inlet Glycol/Water temperature from the required temperature of Glycol/Water refrigerant.

Here is the formula

 Q = M * C * ΔT

In this formula:-

Q = Heat load capacity of Glycol Chiller System

M = Flow rate of the coolant Gallons per hour (GPM)

C= Specific heat of the glycol/water mixture

ΔT = Temperature difference between the inlet Glycol/Water temperature and the required temperature of Glycol/Water refrigerant.

For example: If the flow rate of a coolant is 45 GPM and the ΔT is 15 °F then:

Q = 500 BTU per gallon per hour * 45 GMP * 15 °F = 337500 BTU per hour

Converting BTU per hour into Tons per hour = 337500 BTU per hour / 12000 = 28 Tons/hr.

This will be the capacity of Glycol Chiller with a flow rate of 45 GMP and ΔT 15 °F.

How to Select an Efficient Glycol Chiller System for your Application?

When it comes to choosing an efficient Glycol Chiller System for your application. It seems a bit difficult task.

This guide will help you properly about how can you choose the right Glycol Chiller System for your application to attain maximum results.

Here are four steps to reach your Glycol Chiller System to meet the requirements of your applications.

• Calculate Coolant Temperature:

When you are going to choose a Glycol Chiller System for your application it is important to calculate the inlet coolant temperature for your application.

The glycol coolant travels from your Glycol Chiller System to your application. It can cause a temperature rise.

If you will place your application far away from the Glycol Chiller System, it can increase the potential of heat gain.

The potential heat gain can be minimized by placing the Glycol Chiller System closer to your application.

• Figure Out the Heat Load:

The amount of heat that needs to be removed from your application is important to be calculated.

You can calculate the heat load of your application to choose an efficient Glycol Chiller System by the given formula:

Heat Load = Fluid Density * Flow Rate * Fluid Specific Heat

                                                            * Constant * ΔT°.

The heat load is commonly expressed in watts or BTUs per hr. The heat load value is mostly proved by the manufactures.

• Calculate the Coolant Flow and Pressure:

The coolant flow and pressure are a function of the heat transfer and surface area features of your application that is going to be cooled.

These parameters are commonly provided by manufacturers. A Glycol Chiller System needs to provide the coolant at the proper pressure and flow rate.

If your Glycol Chiller System will provide high heat and flow rate than required for your application, it may damage.

And if these parameters are less than the required coolant flow and pressure. It may not remove properly heat.

• Heat Dissipation of a Condenser:

A Glycol Chiller System you are going to choose for your application must have a high-quality condenser that exhausts the heat into the atmosphere and can dissipate heat into the water supply.

How to Choose the Right Size of Glycol Chiller System for your Application?

After the selection of your Glycol Chiller System, this is another important step to choose the right size of your Glycol Chiller System.

• The required glycol/water temperature for your application.
• The coolant flow rate

Here is a simple and easy formula for you to calculate the size of your Glycol Chiller System according to the need of your application.

1. Calculate the value of temperature difference in degree Fahrenheit as (The input glycol/water mixture temperature (°F) – The required glycol/water temperature (°F)) =ΔT°F.
2. Now, determine the value BTU/hr. = Gallons per Hour * 8.33 * ΔT°F
3. Calculate the value of cooling capacity in tons = (BTU/hr.)/12000
4. Oversize the value by 20% = Ton capacity into 1.2
5. Round of the value if the answer is in decimal.
6. This will be the final size according to the requirements of your application.

For example, what size of Glycol Chiller System is required to cool 11 GPM from 73 °F to 59°F?

• ΔT°F = 73°F – 59°F =14°F.
• BTU/hr. = 11gpm * 60 * 8.33 * 14°F =76969 BTU/hr.
• Cooling Capacity Ton = (76969 BTU/hr.) / 12000 = 6.414 Tons.
• Oversize by 20% = 6.414 * 1.2 = 7.6968.
• A 7.6968 or 8-Ton Glycol Chiller is required.
