PERFORMANCE

SuperAdd, the desiccant-based air conditioning system, has demonstrated its benefits at numerous installations through- out the country. By providing conditioned air at lower humidity levels, owners are saving energy while establishing a more comfortable conditioned environment for customers. By adding a SuperAdd unit to your existing H.V.A.C. you can increase overall system performance and improve conditions in either your present space or in an expanded area. Three SuperAdd models are available to properly match the equipment capacity your building requires with simple installation-the SuperAdd unit is ducted in parallel with the existing return air ductwork.

SuperAdd eliminates the latent load that your air conditioning equipment would normally have to handle. With the new fresh air codes, this may be a substantial part of your air conditioning loads. How is this possible? A Honeycombe desiccant wheel rotates continuously between two counterflow air streams separated by flexible seals. These air streams flow through the dehumidifying and reactivation sectors of the desiccant wheel. The dehumidifying or process air stream is made up of outside and return air . This blend passes through the wheel and gives up its moisture content to the desiccant. Reactivation air is heated and passed through the desiccant wheel to drive off the moisture picked up from the process airstream.

BENEFITS


1) Eliminates the latent load your existing H.V.A.C. normally handles, eliminating costly subcooling and reheating of supply air.
2) Increases the amount of ventilation air in buildings as now required by ASHRAE Standard 62-89 and revised building codes, improving building IAQ,
3) Saves money by decreasing the overall operating time of existing air conditioning equipment due to lower latent loads.
4) Uses natural gas as an energy source for the dehumidifier to remove latent loads, which is less costly than using electrical energy for mechanical refrigeration.
5) May result in a 50% reduction in fan brake horsepower when a supply air volume of .5 scfm per square ft. of space can be maintained, as compared to 1 scfm per square ft. with a conventional system.
6) Ducts in parallel with the main return air duct to easily connect with the present system.

EXPANSION APPLICATION

When used in an expansion application, SuperAdd removes all the latent load from the conventional H.V.A.C. system and conditions the additional latent load from the expansion. This frees up enough sensible cooling capacity in the existing H.V.A.C. system to handle the total sensible cooling load. The desiccant dehumidification approach also means you are circulating less air per square foot, allowing you to slow down your existing supply fan.

CONSTRUCTION

The SuperAdd base is constructed of welded structural 12 gauge galvanized steel. The cabinet is constructed of .052 embossed aluminum panels and sealed water tight. All interior conditioned surfaces are insulated with at least 1" fiber duct board.

OPERATION SEQUENCE

With the main circuit breaker turned on and the "Auto-off-Manual" switch at the electrical panel turned to the automatic position, the retrofit package is cycled by a humidistat in the controlled space. When the humidity in the area is above the setpoint, the dehumidifier drive motor , reactivation and process fans, and reactivation heat are activated. At this time, outside air and a portion of return air are dried and supplied to the conventional equipment. When the humidity level is satisfied in the spaces, the humidistat opens and the drive motor, fans, and reactivation heat are de-energized. At this point, all the return air and outside air are conditioned by the existing conventional equipment.
