What Is an Absorption Chiller? A Comprehensive Review of Advantages, Operation, and Applications | Sari Puya Absorption Chillers
With rising energy costs and the increasing importance of efficient energy utilization, selecting the right cooling system has become a key concern for employers and project managers. In this context, the absorption chiller, as a low-power and environmentally friendly cooling solution, has gained a significant position in industrial and commercial projects.
Sari Puya, as a specialized manufacturer of HVAC equipment, designs and produces various types of absorption chillers, offering professional and cost-effective cooling solutions for large-scale projects.
In this article, we comprehensively explain what an absorption chiller is, how it works, its advantages and disadvantages, and why Sari Puya absorption chillers are considered a reliable and smart choice.
What Is an Absorption Chiller?
An absorption chiller is a cooling system that, unlike vapor compression chillers, uses thermal energy such as steam, hot water, or gas instead of electricity and a mechanical compressor to generate cooling.
In absorption chillers manufactured by Sari Puya, a water–lithium bromide (LiBr) solution is commonly used as the refrigerant and absorbent pair, ensuring safe, stable, and long-term operation.
How Does an Absorption Chiller Work?
The operation of an absorption chiller is based on heat absorption and heat rejection and includes the following main components:
- Generator
In the generator, the lithium bromide solution is heated by a thermal energy source (steam, hot water, or direct flame), causing the refrigerant to separate from the solution. - Condenser
The refrigerant vapor enters the condenser and releases heat, condensing into a liquid. A cooling tower is typically used at this stage. - Evaporator
The liquid refrigerant enters the evaporator and evaporates by absorbing heat from the chilled water circuit. As a result, chilled water is produced and supplied to the cooling distribution system. - Absorber
The refrigerant vapor is absorbed again by the lithium bromide solution, and the cycle continues.
Sari Puya absorption chillers are engineered with precision to ensure high operational stability and minimal wear and maintenance.
Types of Absorption Chillers Manufactured by Sari Puya

By leveraging these benefits, Sari Puya absorption chillers are an excellent solution for industrial, commercial, and infrastructure projects.
Disadvantages of Absorption Chillers
Despite their benefits, absorption chillers also have certain limitations that must be considered:
Requirement for a cooling tower
Higher water consumption compared to air-cooled chillers
Higher initial investment cost
Through optimized engineering design and proper equipment selection, Sari Puya effectively minimizes and manages these limitations.
Applications of Absorption Chillers
Absorption chillers are commonly used in projects where thermal energy is readily available, including:
Power plants
