5.7 Heating System And Refrigeration

Boiler when used in connection with refrigeration system,
must be installed so chilled medium is piped in parallel with
the boiler with appropriate valves to prevent chilled medium
from entering the boiler.
Boiler piping system of hot water boiler connected to heating
coils located in air handling units where they may be exposed
to refrigerated air circulation must be equipped with flow
control valves or other automatic means to prevent gravity
circulation of the boiler water during the cooling cycle.
