Abstract: A process and its relating plant for recycling zinc oxide residues. Thereby, zinc oxide residues are granulated to particles with a size of d80 between 0.3 and 5 mm, preferably between 0.5 and 2 mm. These particles are fed into a roaster where they are thermally treated at a temperature in the range of 500 and 1.200° C., preferably 800 to 1.100° C. in a fluidized bed to form a calcine. The zinc oxide residues are zinc oxide dusts with a particle size below d80 100 ?m, preferably below d80 75 ?m coming from kiln, submerges lances furnaces, ferric reduction furnaces, galvanizing and/or recycling processes, particularly recycling of steel, copper, lead, nickel and/or electronic scrap, and/or that the zinc oxide residues comes from foundry for lead and zinc, ashes and/or dross from a Zamac process, oxide zinc ash, catalysts, melting and casting of Zn and/or zinc slag.

Abstract: A rooftop HVAC unit includes a cabinet, an energy recovery wheel, dampers, and a controller. The energy recovery wheel is configured to be mounted within the cabinet. The energy recovery wheel is configured to transfer heat between an outdoor air stream and a return air stream when in an operational mode, and is further configured not to transfer heat between the outdoor air stream and the return air stream when in a bypass mode. The dampers can direct the outdoor air stream and return air stream through the rooftop HVAC unit, either through the energy recovery wheel or around the energy recovery wheel. The controller is configured to adjust the dampers based on a selection between the operational mode and bypass mode of the energy recovery wheel.
