Define the waste heat from a compressor can be used to heat a building in winter.
Define the waste heat from a compressor can be used to heat a building in winter.
Compressor heat is very critical in the hot days of summer. If the heat arising due to compression is not handled properly, then overheating will take place in the system which will influence the quality of compressed air, and thus the life of the equipment. Thus proper ventilation is required. This waste heat can be further utilized to heat the areas where heating is required.
The areas in which the waste heat can be utilized depends upon its temperature. The waste heat from the compressor if recovered can be used to decrease the cost involved in energy utilization in many industrial and other applications. It has been observed that just 10% (approx.) of the compressor air is converted into useful work in some applications, however 80% of the heat is recoverable i.e., for every single kilowatt (kw) of power input for a compressor, around 0.8 kw is recoverable.
The recovered heat could be used in various applications such as boilers, buildings, for applications. However, the easiest and most common use of the heat of compression is to supplement building heat. In cooler months, the hot air produced by air cooled compressors can be redirected inside the building. Hot water produced by liquid-cooled compressors can also be used in this way, but it is more complicated.
