PDM Air Conditioning offer a range of fresh air heat recovery units for the domestic, industrial and commercial environments. Indoor air quality is one of the most important aspects of occupant comfort. In order to provide a safe, healthy and comfortable indoor environment, minimum ventilation standards need to be provided depending on the pattern of occupancy and functionality of the accommodation. Ventilation is required for one or more of the following purposes:
Ventilation systems are required in an enclosed building to satisfy health, comfort and cooling needs. It will be best provided with a good degree of local control. According to the CIBSE Building Guide, the minimum required fresh air is 5 l/s per person (or 0.5 l/(s m2) while the recommended rate is 8 l/s per person (or 0.8 l/(s m2). Unsatisfactory internal air quality in a cabin will happen with too little fresh air. However, with too much ventilation, unnecessary heat losses will occur with a waste of energy.

Energy Recovery Ventilators
Minimal energy loss, maximum heat recovery, substantial energy savings...
Lossnay heat-exchange technology provides for highly effective ventilation systems with minimal energy loss. The Lossnay core is made up of a cross-flow, plate-fin configuration with a diaphragm constructed of specially processed paper. The advanced heat-transfer and moisture permeability properties of the paper contribute to maximum heat recovery as air circulates through the element. This results in substantial energy savings and contributes to a more comfortable indoor environment.
