Development of By-Pass Blending Station System
Abstract
A new building blending station system named
by-pass blending station (BBS) has been developed
to reduce building pump energy consumption in both
district heating and cooling systems. Theoretical
investigation demonstrated that the BBS can
significantly reduce building pump power for a
typical cooling system when constant water flow is
maintained in the building side. When differential
pressure reset is applied in the building side, more
pump energy can be saved. The BBS also reduces
the pump size and therefore results in lower initial
system cost. A case study was also performed and
demonstrated 42% of annual chilled water pump
energy savings for constant building water flow, and
82% of annual chilled water pump savings for
differential pressure resetting at Omaha, Nebraska.
