Single Effect Absorption Chillers: Efficient Cooling Solutions for Facilities
When it comes to facilities management, maintaining optimal indoor temperatures is crucial. This is where absorption chillers come into play. One type of absorption chiller commonly used is the single effect chiller.
So, what exactly is a single effect absorption chiller? Well, unlike its counterparts, the single effect chiller uses a simple cycle to produce chilled water. It relies on heat energy to drive the cooling process instead of relying solely on electricity.
In a single effect absorption chiller, the refrigeration cycle consists of an absorber and generator. The absorber absorbs vaporized refrigerant from the evaporator section while mixing with a solution known as absorbent.
This mixture then flows down to the generator where heat energy is applied. As a result, the refrigerant separates from the absorbent and becomes vapor again. This vapor then travels back to the condenser where it releases heat and turns into liquid form once more.
One advantage of using single effect absorption chillers in facilities management is their efficiency in utilizing waste or low-grade heat sources like steam or hot water for operation. This can lead to significant energy savings compared to traditional electric-driven chillers.
Furthermore, these chillers are environmentally friendly since they don’t rely heavily on electricity consumption which contributes towards reducing greenhouse gas emissions.

Unlike the single effect chillers, which rely solely on heat energy from a thermal source, double effect chillers utilize both high-grade and low-grade waste heat to produce chilled water.
In a double effect absorption chiller, the refrigeration cycle is divided into two stages or “effects.” The first stage involves the evaporation of a refrigerant under low pressure using high-temperature steam as the heat source. This vapor then enters the second stage where it is further heated by another thermal energy source. As this vapor expands through an expansion valve, it absorbs more heat and cools down significantly, resulting in the generation of chilled water for air conditioning or process cooling applications.
The use of multiple effects allows double effect absorption chillers to achieve higher coefficient of performance (COP) ratings than single-effect units. In other words, they can produce more cooling output for each unit of input energy consumed. This improved efficiency not only helps reduce electricity costs but also minimizes environmental impact by lowering greenhouse gas emissions.

How do Absorption Chillers Work?
Absorption chillers are fascinating machines that use a unique process to provide cooling in facilities. But how do they actually work? Let’s dive into the inner workings of absorption chillers and uncover their secrets.
At the heart of an absorption chiller is a refrigerant-absorbent pair, typically water and lithium bromide. The cycle begins with a generator where heat is applied, causing the refrigerant (water) to evaporate. This steam then rises to the condenser, where it transfers its heat energy to a cooling medium such as air or water.
Once cooled, the steam condenses back into liquid form, releasing its heat and becoming ready for reuse. The next step is crucial – this liquid refrigerant flows through an absorber where it comes into contact with the absorbent (lithium bromide). The absorbent absorbs the refrigerant vapor, creating a concentrated solution.
The concentrated solution then moves on to another vessel known as a desorber or generator. Here, low-pressure steam heats up this concentrated mixture, causing the absorbed refrigerant to separate from the absorbent. This released vapor then returns back to the beginning of our cycle at the generator stage.
Meanwhile, within yet another component called an expansion valve or throttle valve, pressure drops occur which causes some of our now gaseous refrigerants’ temperature to drop dramatically – resulting in chilled water production! This chilled water can now be circulated throughout your facility for cooling purposes.
Absorption chillers work by using heat sources like natural gas or waste heat for generating high-pressure vapors that get condensed into liquids again when giving off thermal energy which creates chilled fluid able enough cool down whole buildings!
Understanding how absorption chillers work allows us to appreciate their efficiency and effectiveness in providing cooling solutions while minimizing electricity usage compared to traditional compression-based systems. These innovative machines have found applications in various industries ranging from commercial buildings and hospitals to industrial processes requiring cooling. So the next time you feel a cool breeze on a hot day,
