Chiller Fundamentals
What is a Chiller System
At Abontika HVAC Engineering, we deliver complete chiller system solutions from cooling load calculation and equipment supply to full integration, commissioning, and maintenance support.
What is a Chiller System?
A chiller system is a central air conditioning solution that removes heat from a building or industrial process using chilled water circulation. It is commonly used in large-scale facilities where conventional air conditioning systems are not efficient or practical.
Chiller systems operate by transferring heat through refrigerant cycles and distributing chilled water to Air Handling Units (AHU) or Fan Coil Units (FCU) to maintain controlled indoor temperatures.
A properly engineered chiller system delivers centralized cooling, reliable operation, and the flexibility required for large buildings and critical facilities.
Why Chiller Systems Matter in Bangladesh
In Bangladesh's high-temperature and high-humidity climate, large buildings and industrial operations require reliable and efficient cooling systems. Chiller systems provide stable cooling for large floor areas, efficient energy consumption for long-term operation, better control for temperature-sensitive environments, and scalability for future expansion.
