Air Compressor Heat Recovery

1. HEAT RECOVERY & COMPRESSED AIR SYSTEMS

2. INTRODUCTION Heat Loss Wasted air due to : Leaks Artificial demand inappropriate Heat recovery in compressed air systems is a process that utilizes the heat generated during the compression of air to improve energy efficiency and reduce costs What to do? HEAT RECOVERY

3. AIR COOLED METHOD HARVEST HEAT OIL FREE OIL INJECTED WATER COOLED OIL FREE OIL INJECTED

4. AIR-COOLED The hot air is used to heat up the room and the adjacent areas In an air-cooled system, the hot air temperature can range from 17 °C to 25 °C higher than the ambient air temperature. The temperature range applies to both oil-free and oil-injected. A mbient air Hot air

5. WATER-COOLED OIL-FREE Oil-free signifies that it doesn't use oil for lubrication in the compression chamber. Typically , Chilled Water Return (CWR) temperatures are around 80 °C , but some companies may achieve temperatures as high as 90°C OIL-INJECTED Function is to cool and lubricate the compressor element's moving parts and the air being compressed internally. Chilled Water Return (CWR ) temperatures generally hover around 70 °C , although certain companies can reach temperatures as low as 60 °C. cws cws

6. CONCLUSION AIR-COOLED (OIL-FREE) AIR-COOLED (OIL-INJECTED) WATER-COOLED (OIL-FREE ) WATER-COOLED (OIL-INJECTED ) Air ambient + (17 °C - 25 ° C) 80 °C / 90 °C 60 °C / 70 °C In conclusion, among the four methods for heat recovery in air compressors , the water-cooled oil-injected system stands out as the most favourable choice . This preference is primarily due to its temperature profile , which is notably well-aligned with the project's requirements, ensuring accuracy and optimal efficiency.
