modelCoolingAndHeating

Active beam unit for heating and cooling

Extends from BuildingSystems.Fluid.HeatExchangers.ActiveBeams.Cooling.

Information

This model is identical to BuildingSystems.Fluid.HeatExchangers.ActiveBeams.Cooling, except that an additional water stream and convector is added to allow for heating in addition to cooling.

For a description of the equations, see the User's Guide.
