A Heat Recovery Unit for HVAC is a thermodynamic arrangement that recovers a part of the energy wasted through application of heating, venting, and air conditioning systems. A heat recovery unit is a very effective means to reclaim the difference of heat energy between the inside of a premise and that outside it.
A Heat recovery unit works on the simple principle of recovery of as much energy as is present in the exhaust air that is being driven out of the premise.
Among the heat recovery unit manufacturers, the best is the one manufactured by Ingersoll Rand for. Here are some more details about IR’s Heat Recovery system for Contact-Cooled Compressor
A working compressor generates heat from 2 sources:
As per the latest studies, while 15% of this heat is unrecoverable, about 85% of it is recoverable and can be utilized for various purposes.
It is here that Ingersoll Rand’s Heat Recovery System comes into play, recovering almost all of the 86% energy through ingenious design and technology. For a contact-cooled air compressor, rated at 55KW ~ 350KW a recovery efficiency of ≥ 74% of rated power is achieved.
