ABSTRACT:
In a heating, ventilation and air conditioning system such as a heat pump having a multi-zone hydronic thermal distribution system or such as an air conditioner, a novel condensate removal apparatus removes condensate from each zone fan coil. Each fan coil uses a valve to drain condensate from a fan coil drip pan into a drainage conduit. The drainage conduits from each valve carry condensate to a tank. The tank acts as a manifold for fluid collection from the different fan coils. A single pump draws condensate from fan coils through drainage conduits to the tank. This same pump draws a vacuum in the tank and the drainage conduits. The pump uses a single outlet conduit to discharge condensate.
