Heating Ventilating Air Conditioning Guide 1939 ENCLOSED RADIATORS The general effect of an enclosure placed about a direct radiator is to restrict the air flow, diminish the radiation and, when properly designed improve the heating effect.

Heating Ventilating Air Conditioning Guide 1939 Down-Feed Two-Pipe Vapor System In the down-feed two-pipe vapor system the steam is carried to the ton of the building, the top of the vertical riser constituting the high point of the system, and the horizontal supply main is sloped down from this location to the far ends of each branch.
