Abstract
A package heat exchange system having a burner positioned in the central plenum of a first heat exchanger and supplied with a fuel-air mixture through a blower supplied with fuel through a pressure regulator which requires a negative pressure at the blower input to draw gaseous fuel through the pressure regulator. Thermal energy is transferred from the first heat exchanger to a second heat exchanger or from the second heat exchanger to a third heat exchanger by pumped fluids and transferred to or from the second heat exchanger and air blown through the second heat exchanger to heat or cool the air with blowing of the air, operation of the burner and heating of the first heat exchanger when the burner is not operating being used to maintain the temperature of the surface of the first heat exchanger which contacts the products of combustion of the burner above the dew point of the products of combustion.
