Detailed Description

Loop is the base class for HVAC air and water loops.

This class provides basic functionality to traverse a loop and locate components. Currently there are two types of loops AirLoopHVAC and PlantLoop. This interface reflects the commonality between the two. Loops in combination with HVACComponents offer a very simple interface to create new systems in EnergyPlus.

The following is an example of building a new HVAC system composed of an AirLoopHVAC with this c++ interface.

Model model = Model();

AirLoopHVAC airLoop = AirLoopHVAC(model);

AirLoopHVACOutdoorAirSystem oaSystem = AirLoopHVACOutdoorAirSystem(model);

FanConstantVolume fan = FanConstantVolume(model);

CoilCoolingDXSingleSpeed  coolCoil = CoilCoolingDXSingleSpeed(model);

CoilHeatingGas heatingCoil = CoilHeatingGas(model);

oaSystem.addToNode( airLoop.supplyOutletNode() );

fan.addToNode( airLoop.supplyOutletNode() );

coolCoil.addToNode( airLoop.supplyOutletNode() );

heatingCoil.addToNode( airLoop.supplyOutletNode() );

airLoop.addBranchForZone("Zone1");

The interface also allows you to retrieve a ModelObject and clone it into a new model thereby making a new copy. The clone algorithm is intellegent enough to bring along all of the connected pieces as it is appropriate.

Model newModel();
AirLoopHVAC newAirLoop = model.getModelObject(airLoop.handle())->clone(newModel);

The HVACComponent::addToNode function is intellegent. The add routine is context sensitive so for example adding a WaterToAirComponent to an air node will connect the air side ports, adding it to a plant loop node will connect the water side ports.

Model model = Model();

AirLoopHVAC airLoop = AirLoopHVAC(model);

PlantLoop plantLoop = PlantLoop(model);

CoilCoolingWater waterCoolingCoil = CoilCoolingWater(model);

waterCoolingCoil.addToNode( airLoop.supplyOutletNode() );

waterCoolingCoil.addToSplitter( plantLoop.demandSplitter() );
