  • Patent number: 5765629
    Abstract: A two-stage steam condenser that prevents freezing from occurring in the tube rows by continual purging of the tube rows. Such continual purging prevents any steam from back-flowing into a tube row thereby eliminating the possibility that condensate or noncondensable gases will become trapped therein. This is achieved by isolating each of the tube rows in the second stage of the condenser so that the pressure of one tube row is not exposed to the pressure occurring in another adjacent tube row. The condensate collected in the various tube rows of this second stage is delivered to a common drain pot that is hydraulically balanced to accommodate the various pressures in these tube rows. Such hydraulic balancing also prevents any back-flowing from occurring from one tube row into another.

  • Patent number: 5193610
    Abstract: The present invention relates to an apparatus for defrostable ventilation systems which include an element for the transfer of heat from warm exhaust air (taken from inside a building) to cooler exterior fresh air which is drawn into the building, the system using warm interior air as defrost air for defrosting the system during cool weather. The present invention in particular provides an apparatus whereby, during a defrost cycle, the interior defrost air may circulate through both of the fresh air and exhaust air paths for delivery back into the building, i.e. the warm interior air may be confined to circulate from the interior of the building into the ventilation apparatus and back to the interior of the building. The apparatus can thus use interior air as defrost air while diminishing or avoiding the creation of a negative air pressure in the building.
