When you figure out cooling capacity, you make sure your chiller is the right size. The right size keeps your system working well and saves money. If you choose the right cooling capacity, you do not waste energy or money. Picking the right chiller helps your company work better and save money for a long time.

How to Choose a Chiller

Assess Cooling Needs

You should first know your cooling needs. This helps you not buy a chiller that is too big or too small. Here is a simple guide to help you:

Find all things that make heat in your building. Machines, lights, and people all add heat.
Measure the space you want to cool. Bigger spaces need more cooling.
Check what you store in the area. Some things give off more heat than others.
Decide what temperature you need to keep. This will help you pick the right chiller.
Notice how often doors open and close. More people coming in and out means more heat.
Think about your local weather. Hot places need more cooling.
Look at how well your building is insulated. Good insulation keeps heat out.
Review your daily work. Equipment and lights can make extra heat.

Tip: Write down all these things. This list will help you find the right cooling size and pick a chiller that fits your needs.

Determine Water Temperature

You need to know what water temperature your process or building needs. The difference between water going in and out changes how much energy you use. Colder water uses more energy. Warmer water can save energy but might not work for your needs.

Check what your process needs for water temperatures.
Use a thermometer to see the water temperature now.
Write down the temperature range you want.

Note: Picking the right water temperature helps you use less energy and get good results.

Calculate Chiller Capacity

Finding the right size is very important. If your chiller is too big, you waste energy. If it is too small, it will not cool enough. Use these easy formulas to help you:

Formula Description	Formula
Chiller Capacity (kW)	Q = TR × 3.517
Power Requirement based on COP	Power = Cooling / COP
Cooling Load Calculation (TR)	TR = Area (sq.ft) / 500
Air Flow Calculation (CFM)	CFM = 400 × TR
Chiller Power Calculation (kW)	kW = TR / COP
Energy Efficiency Ratio (EER)	EER = Cooling Capacity (BTU/hr) / Power (W)

Example:
If you have 5,000 square feet to cool, use this formula:
TR = Area (sq.ft) / 500
TR = 5,000 / 500 = 10 tons
To change tons to kW:
Q = TR × 3.517 = 10 × 3.517 = 35.17 kW
This tells you how much cooling your chiller needs.

Evaluate Chiller Components

Check the main parts of each chiller before you buy. Look at the compressor, condenser, evaporator, and controls. Good parts help your chiller work better and last longer.

Pick compressors that use less energy. Scroll and screw types are good choices.
Choose condensers that move heat well. This helps save energy.
Make sure the evaporator fits your needs.
Get chillers with smart controls. These help you watch and change how your chiller works.

Callout: Always look for certifications and ask how long each part should last.

Select Chiller Type

Pick a chiller that fits your building and weather. There are two main types: air-cooled and water-cooled. Each type has different needs for energy and care.

Chiller Type	Energy Efficiency	Maintenance Requirements
Air-Cooled Chillers	Lower efficiency; uses outside air	Needs less care; no extra systems needed
Water-Cooled Chillers	Higher efficiency; cools better	Needs more care; uses pumps and towers

Air-cooled chillers are good for small spaces and cool weather. They are easy to take care of.
Water-cooled chillers work better for big buildings or hot places. They need more care and extra equipment.

Key comparison factors: Always check energy use, care needs, and cost before you pick a chiller.

Rules about the environment also matter. Many places now want chillers with low-GWP refrigerants. The EU started to stop using high-GWP refrigerants in 2015. By 2020, many companies used safer ones like R290. So, you should look for chillers with low-GWP refrigerants to follow the rules and save energy.

Note: Picking the right chiller and refrigerant helps you save energy, spend less money, and follow the rules.
