What Is a Chiller and Why Is It Important?

A Chiller is a refrigeration unit that removes heat from water or a secondary cooling medium through a vapor-compression refrigeration cycle. The chilled water is then circulated through the building or industrial process to absorb heat and maintain the required temperature.

In commercial HVAC, chillers are used for:

shopping malls

hotels

hospitals

office buildings

apartments

schools

restaurants

commercial complexes

In industrial process cooling, chillers are used for:

plastic injection molding

electroplating

electronics manufacturing

chemical processing

food and beverage

pharmaceutical production

mechanical processing

data centers and communication rooms

laboratories and precision manufacturing

A correctly selected Chiller improves product quality, stabilizes process temperature, reduces equipment failure and helps lower long-term operating costs.

HISURP Chiller Product Family

HISURP provides four major chiller categories to match different project needs:

[Air Cooled Scroll Chiller] Suitable for small and medium commercial HVAC, modular cooling/heating systems, water-limited areas and projects requiring easy installation without cooling towers.

[Air Cooled Screw Chiller] Suitable for larger buildings, factories, data centers, process cooling and projects needing high-capacity outdoor cooling. Optional free cooling is available for year-round cooling applications.

[Water Cooled Scroll Chiller] Suitable for compact industrial process cooling, plastic molds, electroplating tanks, electronics, food preservation and medium/small capacity production cooling.

[Water Cooled Screw Chiller] Suitable for large commercial buildings and heavy industrial cooling projects requiring high efficiency, stable chilled water and large cooling capacity.

How to Choose a Chiller?

1. How to choose a Chiller for my project?

To select the correct Chiller, buyers should confirm the following information:

Required cooling capacity

Chilled water inlet and outlet temperature

Cooling water temperature if water cooled

Ambient temperature if air cooled

Cooling medium: water, glycol solution or brine solution

Application: comfort cooling or process cooling

Installation location: indoor, outdoor, rooftop, equipment room

Power supply: voltage, phase and frequency

Noise requirement

Water availability

Need for heating or hot water

Need for remote control or BMS communication

Special requirements such as low temperature, anti-corrosion, free cooling or modular combination

If the project lacks cooling tower water, an Air Cooled Scroll Chiller or Air Cooled Screw Chiller is usually easier to install. If the project has cooling water available and prioritizes high energy efficiency, a Water Cooled Scroll Chiller or Water Cooled Screw Chiller may be a better choice.

2. What is the difference between air cooled and water cooled chillers?

An air cooled chiller rejects heat to outdoor air through condenser fans. It does not require a cooling tower, cooling water pump or complicated cooling water system. It is simple to install and especially suitable for water-scarce areas.

A water cooled chiller rejects heat through cooling water and usually works with a cooling tower. It can achieve higher energy efficiency in many projects, especially large-capacity systems, but requires more water-side equipment and regular water treatment.

3. What is the difference between scroll chiller and screw chiller?

A scroll chiller is usually compact, low noise, easy to operate and suitable for small to medium cooling capacity. It is commonly used in light commercial HVAC and industrial process cooling.

A screw chiller uses screw compressors and is better suited for medium to large cooling capacity, continuous operation and applications requiring capacity regulation. Screw chillers are widely used in hotels, hospitals, factories, shopping malls, office buildings, data centers and industrial cooling plants.

4. Which Chiller is best for industrial process cooling?

For small and medium process loads, such as plastic molds, electroplating tanks, electronics equipment and food cooling, a Water Cooled Scroll Chiller or air cooled scroll industrial chiller is often suitable. For larger process cooling systems in chemical, pharmaceutical, semiconductor, data center or industrial plants, an Air Cooled Screw Chiller or Water Cooled Screw Chiller is recommended.
