Reducing energy consumption and carbon emissions is a key objective for every building design. But HVAC systems, not buildings, consume energy. To enable you to test and optimise plant and controls, IES <VE> has developed Apache HVAC. It offers almost unlimited flexibility in system configuration and specification, and its detailed thermal simulation results in accurate carbon and energy figures. You can analyse system performance, see how the plant interacts with the building and assess thermal comfort. So you get the HVAC system that's right for your building, right for your budget and right for the environment.
What ApacheHVAC does:
ApacheHVAC enables you to simulate heating, ventilation and air-conditioning systems quickly and easily. It uses a flexible component-based approach which enables you to assemble systems on-screen as designed.
ApacheHVAC covers all common system types including VAV, CAV, fan-coil, VVT, displacement ventilation, hollow-core slab systems and under-floor heating.
ApacheHVAC is dynamically integrated with the IES building simulation software (ApacheSim). This is vital for ensuring reliable estimations of plant sizes, optimisation of the plant/controls operation and accurate assessment of carbon emissions.
The principal application areas for ApacheHVAC are:
· HVAC system design
· Component sizing
· HVAC control design
· Mixed mode system design
· Energy consumption prediction
· Carbon emissions
· Building Regulations
· CFD boundary conditions.
How ApacheHVAC works:
ApacheHVAC Methodology
ApacheHVAC enables you to define HVAC plant components and controls schematically, with easy-to-use graphical tools for placing, moving, copying and deleting. ApacheHVAC runs alongside ApacheSim to provide a fully integrated simulation of plant, controls and building.
ApacheHVAC components:
· Heating and cooling coils
· Fans and dampers
· Mixing boxes and economisers
· Steam and spray humidifiers
· Heat recovery
· Duct heat loss
· Room conditions
· Radiators and chilled ceilings (dynamic model)
· Direct-acting heaters and chilled beams
· Controllers sensing temperature, humidity, enthalpy, flow rate or solar radiation
· Controllers sensing the difference between two variables
· On-off and proportional control
· Cascaded control logic
· Boilers, chillers and heat pumps, including ancillary pump and fan consumptions.
Commercial Benefits:
ApacheHVAC offers you great commercial and technical advantages. It enables you to optimise HVAC system operation, and to minimise energy consumption and carbon emissions. Via ApacheSim, it allows the most complete thermal analysis that is possible for a building.
