❑ System does not have a common return system (a three -pipe system) for both hot water
and chilled water.
13.3 Two -Pipe Changeover System (Section 1318.2.8.2)
❑ System is not a Two -Pipe Changeover System
❑ Complies. System is:
a. Designed to allow a deadband between changeover from one mode to the other
of at least 15 °F outside air temperature.
b. Designed to operate and provided with controls that will allow operation in one
mode for at least four hours before changing over to the other mode.
c. Provided with reset controls that allow heating and cooling supply temperatures
at the changeover point to be no more than 30 °F apart.
The plans /specs show compliance in
the following locations:
13.4 Hydronic (Water Loop) Heat Pump System (Section 1318.2.8.3)
❑ System is not a Hydronic (Water Loop) Heat Pump System
❑ Complies. Hydronic heat pumps connected to a common heat pump water loop with central
devices for heat rejection (e.g., cooling tower) and heat addition (e.g., boiler) have the
following:
a. Controls installed capable of providing a heat pump water supply temperature
deadband of at least 20 °F between initiation of heat rejection and heat
addition by the central devices (e.g., tower and boiler).
b. Closed- circuit tower (fluid cooler) has either an automatic valve
installed to bypass all but a minimal flow of water around the tower
(for freeze protection), or low- leakage positive closure dampers.
c. Open- circuit tower installed directly in the heat pump loop has an automatic
valve installed to bypass all heat pump water flow around the tower. Open -
circuit towers used in conjunction with a separate heat exchanger to isolate
the tower from the heat pump loop are controlled by shutting down the
circulation pump on the cooling tower loop.
�,� d. A two- position valve at each hydronic heat pump for hydronic systems
5 "`' =`�'' having a total pump system power exceeding 10 hp.
