With water-cooled compressors it is possible to recover a high proportion of the intake energy in the form of hot water which can be used for space heating, feed water for boilers, etc in a large factory. A typical system for heat recovery is shown in Figure 2. With aircooled compressors, the hot air leaving the intercooler and aftercooler can be directed to an adjacent room for space heating as in Figure 3.
