Heating Ventilating Air Conditioning Guide 1938 centage of outside air should be kept as low as possible to maintain the air in the proper condition in order to minimize the heat or cooling load.

Heating Ventilating Air Conditioning Guide 1939 In considering both the transmission and infiltration losses, the more ^ exact procedure would be to select the outside temperature and the wind ' velocity corresponding thereto, based on Weather Bureau records, which would result in the maximum heat demand.

Heating Ventilating Air Conditioning Guide 1939 As is the case with the complete combustion of almost all fuels, the products of combustion for gas are carbon dioxide (CO.) and water vapor with just a trace of sulphur trioxide (S03).

Heating Ventilating Air Conditioning Guide 1939 freezing temperature, throttling the steam supply may result in freezing the condensate in the bottom of the coil if the tubes are of the variety nof provided with internal distributing pipes, or an equivalent arrangement If these are used, there is little danger of freezing the condensate as lon as the leaving air temperature is not allowed to fall below about 40 pS As an added precaution with both steam and water coils the outside air inlet dampers are often closed automatically when the fan is stopped to avoid trouble caused by very cold outside air drifting in during off periods A typical arrangement of water cooling coils is shown in Fig. 11.
