Heat Recovery Ventilation Systems

Heat Recovery Atmosphere Purification

Dehumidifiers on their own do an excellent job of drying the air and recovering heat from the water vapour. Left to themselves however they will simply recycle the same air over and over again and the pool hall atmosphere may eventually become stale muggy and smelly. Opening doors and windows, and using conventional extractor fans, will quickly provide fresh air, but this could be costly during colder months, because so much heat can escape from the pool hall. The answer is heat recovery ventilation. This is not an alternative to dehumidification. Ideally both should be considered together.

A heat recovery unit has two fans, one in, and one out. The two air streams pass on either side of an efficient air heat exchanger, which transfers a high proportion of the heat from the warm but stale air going out, to the cold fresh air coming in, offering 70% heat recovery or more.
