American Society of Heating and Ventilating Engineers Guide, 1930 The heating of the water usually is controlled by means of a thermostat placed in the path of the saturated air leaving the humidifier and con trolling the heater through which the spray water passes.

American Society of Heating and Ventilating Engineers Guide, 1931 Making the rough assumption that the neutral zone3 is located at mid height of a building, and that the temperature difference is 70 F, the following formulae may be used to determine an equivalent wind velocity to be used in connection with Tables 1 and 2 that will allow for both wind velocity and temperature difference: Me = y/M1 - 1.75 a where Mt = a/M!

American Society of Heating and Ventilating Engineers Guide, 1934 Except for heating-up periods or other times when the heat gain is not greater than the heat loss, a system of this type can be operated without artificial heat, with outdoor temperatures as low as 40 F.

American Society of Heating and Ventilating Engineers Guide, 1934 Indirect heaters generally consist of steam boilers in connection with heat exchangers of the coil or tube types which transmit the heat from the steam to the water.
