Abstract: Heating, ventilating, air conditioning or refrigeration (HVAC&R) systems and associated outdoor horizontal discharge units are provided. The units include a heat exchanger. The heat exchanger includes a plurality of manifolds. The heat exchanger also includes a plurality of multichannel tubes in fluid communication with the manifolds. Each multichannel tube includes a plurality of parallel flow paths through which an internal fluid flows. Each flow path extends lengthwise through its respective multichannel tube. The heat exchanger further includes a plurality of fins disposed between the multichannel tubes for transferring heat between the external air and the internal fluid flowing through the flow paths. The units also include a fan configured to blow air horizontally through the heat exchanger such that the air discharges the unit horizontally through at least one side of the unit.

Abstract: The invention is generally directed to an evaporative humidifier having a water distribution system capable of quietly maintaining a continuously saturated wicking element through the use of a pump and water distribution troughs that allow water to be continuously flushed onto the tops of the wicking elements such that greater humidification of the air is achieved and the life of the wicking elements are extended.
