Cooling Efficiency with Ventco Engineering
In Singapore’s tropical climate, where high humidity and soaring temperatures are a daily norm, effective cooling systems are essential for maintaining comfortable indoor environments – whether in commercial buildings, industrial facilities, or healthcare institutions.
At Ventco Engineering, we specialise in providing complete cold room solutions, commercial refrigeration systems, and chilled water systems that are tailored for Singapore’s unique operating conditions. This article explains how chillers work, their different types, and why chilled water systems are increasingly favoured across various industries.
What Is a Chiller?
A chiller is a sophisticated machine designed to remove heat from a liquid – usually water – and circulate that chilled water throughout a building or facility to absorb ambient heat. It forms the core of a chilled water system, which provides reliable cooling across multiple zones in a property.
Using the principles of the refrigeration cycle, chillers transfer heat from water to the surrounding air or another cooling medium. This chilled water is then distributed through a network of insulated pipes to air handling units, fan coil units, or process equipment, depending on the application.
Chillers are commonly used in:
- Commercial buildings (e.g. office towers, malls, hotels)
- Data centres
- Industrial and manufacturing facilities
- Hospitals and laboratories
Chiller vs Chilled Water System: What’s the Difference?
While a chiller is the main unit that performs the heat removal, the chilled water system refers to the entire cooling infrastructure. This includes:
- Chillers
- Chilled water pumps
- Cooling towers (for water-cooled systems)
- Insulated piping network
- Air handling units or fan coil units
Think of the chiller as the “engine” and the chilled water system as the entire “vehicle” that delivers cooling throughout a building.
Common Types of Chillers
Different applications require different types of chillers. At Ventco Engineering, we offer a range of customisable chiller solutions based on your operational needs:
-
Centrifugal Chillers
- Uses centrifugal force from a high-speed impeller to compress refrigerant.
- Best suited for large buildings and facilities due to high cooling capacity.
-
Oil-Free Centrifugal Chillers
- Utilises magnetic bearings and direct-drive technology to eliminate oil use.
- Offers lower energy consumption and less maintenance.
-
Modular Chillers
- Flexible, scalable units suitable for smaller buildings or where space is limited.
- Can be stacked or expanded as your cooling demands grow.
- Often uses low-GWP (Global Warming Potential) refrigerants for environmental compliance.
-
Absorption Chillers
- Runs on heat rather than electricity (e.g. gas, hot water, steam).
- Ideal for facilities with waste heat or where sustainability is a priority.
Why Choose a Chilled Water System?
Chilled water systems offer several strategic advantages, especially for large or complex buildings in Singapore:
-
Energy Efficiency
Centralised systems use less energy compared to multiple standalone air-conditioning units. This can significantly reduce long-term operating costs — especially important with rising electricity rates.
-
Scalability
Easily expandable or downsized to meet changing cooling demands. Perfect for buildings undergoing renovation, expansion, or retrofitting.
- Zoning Capabilities
Allows for precise temperature control across different areas or floors of a building. This improves occupant comfort and reduces energy waste.
-
Lower Maintenance
Fewer moving parts and centralised control systems mean reduced maintenance requirements, saving both time and cost over the system’s life cycle.
-
Sustainable Cooling
With greater compatibility for energy-efficient and low-GWP refrigerants, chilled water systems are more environmentally friendly and align with Singapore’s Green Mark and BCA sustainability goals.
Where Are Chilled Water Systems Used in Singapore?
Chilled water systems are widely adopted across sectors that demand reliable, efficient, and large-scale cooling:
- Commercial Office Buildings
- Shopping Malls & Retail Centres
- Hospitals & Healthcare Facilities
- Hotels, Resorts & Convention Centres
- Data Centres
- Industrial Plants & Manufacturing Facilities
These systems are particularly popular in Singapore due to their ability to perform well in high humidity and urban environments where cooling efficiency is crucial.
