Cooling systems play a vital role in various industrial sectors, and one of the technologies currently being discussed is the BROAD absorption chiller. In this article, we will uncover the secrets behind the workings of this advanced technology in an informative yet easily understandable manner.
By employing this cooling technology, we will explore the workings of a truly revolutionary cooling system. Furthermore, explanations will be presented in a simple yet comprehensive style to cater to a wide audience.
1. Principles of Absorption Chillers
Let’s start with the basics. Absorption chillers operate on an intriguing principle that involves absorption and evaporation. Essentially, an absorption chiller uses a heat source to produce cooling in chilled water, providing heating and hot water separately or simultaneously. Renowned for their water-cooled design, absorption chillers offer versatile solutions for cooling, heating, and hot water needs across various settings. What makes them stand out is their adaptability to diverse energy sources:
- Natural Gas, Town Gas, Bio Gas
Harness the power of natural gas or bio gas to adopt cooling solutions that are not only energy efficient but also environmentally friendly, thus supporting environmental conservation efforts and reducing carbon footprint.
- Dual Gas/Oil Fuel, Gas & Waste Heat Hybrid (Multi-Energy)
Utilize combinations of dual fuel, such as gas and oil, and innovative hybrid configurations of gas/waste heat to create solutions that not only enhance energy efficiency but also optimize the use of available resources. This approach can yield dual benefits in terms of operational efficiency and environmental impact reduction.
- Waste Heat from Industrial Waste Streams: Steam, Hot Water, Exhaust, Multi-Energy Sources, etc.
Leverage waste heat from various industrial processes, such as power generation, by utilizing resource streams like steam and hot water to create sustainable cooling solutions. This not only reduces energy wastage and minimizes environmental impact but also optimizes the use of existing resources for more productive and environmentally friendly purposes.
Imagine Earth as a giant playground where mountains and beaches set the stage for a unique pressure performance, with absorption chillers at the center of it all.
In the mountains, like the mighty Mount Everest, the pressure is akin to a gentle whisper, measuring around 7.1 pascals. It’s like nature turning down the volume knob. Now, enter the absorption chiller, working on vacuum principles, where the pressure inside is approximately 800 pascals. It’s as if the chiller creates a comfortable bubble amidst the low-pressure ambiance of the mountains.
On the flip side, let’s head to the beach, where the average sea level pressure is around 101.3 kilopascals, providing that atmospheric hug. Here, the absorption chiller continues its performance, maintaining a 800-pascal vacuum inside, like a cool character amidst the lively coastal pressure.
So, picture this – the absorption chiller orchestrating its cooling symphony, dancing between the serene mountain pressure and the lively beach atmosphere. It’s the pressure differential ballet, with the chiller as the star performer, creating chilly vibes amidst Earth’s diverse pressure landscapes.
We’ll break down the process into simple steps, allowing you to grasp the concept without getting lost in technical jargon.
A. Double Stage Absorption Chiller
B. Single Stage Absorption Chiller
Input heat energy heats LiBr solution to 140℃ and generates vapor, which is then condensed into water by cooling water. When the refrigerant water enters the evaporator (in high vacuum condition), its temperature immediately drops to 5℃ and is sprayed over the evaporator tubes, causing the chilled water to drop from 14℃ to 7℃ for cooling. The refrigerant water absorbs heat from the air conditioning system and evaporates, then is absorbed by concentrated LiBr solution from the generator. The cooling water takes away the heat and rejects it into the air. Diluted solution is pumped into HTG and LTG separately to be heated to begin the process all over again. Note: lithium bromide is a salt with strong hygroscopicity, non-toxic and harmless, with no greenhouse effect and no damage to the ozone layer.
In summary, PT. BROAD Group Indonesia’s Absorption Chillers present a groundbreaking innovation in cooling technology. Operating on absorption and evaporation principles, these chillers demonstrate versatility in utilizing eco-friendly energy sources for cooling, heating, and hot water applications.
Our exploration led us to the unique pressure performance of the absorption chiller on Earth’s stage. Whether in the tranquil mountains at 7.1 pascals or the vibrant beaches at 101.3 kilopascals, the chiller maintained an 800-pascal vacuum, creating a cooling symphony amidst diverse pressure landscapes.
Breaking down the process into simple steps, from double-stage to single-stage absorption chillers, we emphasized their efficiency in generating chilled water for cooling. The use of lithium bromide underscores their eco-friendly nature with no harm to the ozone layer.
In essence, PT. BROAD Group Indonesia’s Absorption Chillers not only bring a revolutionary cooling solution but also embody a commitment to sustainability, adaptability, and efficiency in the dynamic field of cooling technology.
