modelVariableSpeedWithHeatPumps
Validation model for the control logic of variable speed primary pumps in heat pump plants
Information
This model validates Buildings.Templates.Plants.Controls.Pumps.Primary.VariableSpeedWithHeatPumps with two plant equipment and two primary pumps and for the following configurations.
-
Heating-only plant with headered primary pumps (components
ctlPumPriHdrHea*) -
Heating and cooling plant with headered primary pumps (components
ctlPumPriHdr*) -
Heating and cooling plant with common dedicated primary pumps (components
ctlPumPriDedCom*) -
Heating and cooling plant with separate dedicated primary pumps
(components
ctlPumPriDedSep*) -
Primary pumps commanded at fixed speed (component names as listed above,
without a suffix) or Δp-controlled (components
*Dp)
