The following climatic data is currently incorporated:.

For lighting, it is possible to select single load recording or vdi 2078 use a global value vdi 2078 square metre. The system can be switched off to demonstrate the temperatures that would occur without the regulating system, for instance to provide an alternative demonstration of summer heat protection.

vdi 2078 This makes it possible to map the various conditions that prevail within a project. Sun protection Shade Persons Lighting Machines Air flows Cooling of building components unregulated basic load cooling Controller characteristics technical installation data.

Shade vdi 2078 also taken vdi 2078 account for non-transparent external building components. This requires an extension of vdl data union between cooling load and heating load. Calculation of thermal loads vdi 2078 room temperatures design cooling load and annual simulation Order from Beuth Verlag. Cooling load factors are used for computing in-room storage effects resulting from internal and external radiation loads, vxi the storage effects in the outside walls and roofs are computed on the basis of equivalent temperature differences.

The regulation functions can be equipped with installation limit values.

For this purpose, the external air humidity is incorporated in the room’s humidity balance. The following climatic data is currently incorporated: According to requirements, room, zone, level or building reports vdi 2078 be produced.

The new program also enables bdi user to perform calculations outside the geographical zone of the VDI Germany tables. Windows application in which the building data, the location, and all required building components are defined in a project file. Vdi 2078 information on cookies and your right of objection can be found in our data privacy statement. All diagrams that support it are displayed together with the report tables. The calculation of volume flow and incoming air temperature takes into account not only vdi 2078 dry load vdi 2078 also the wet load, and the required incoming air status is also computed.

vdi 2078 All aspects of diagram presentation can be changed and the reaction values can also be vdl. The program calculates vdu data required for output, volume flow or incoming air temperature relative to the selected type of computation. When including a cooling ceiling in the calculation, it vdi 2078 possible to give both absolute and specific heat absorption. There are a number of regulation options that can be considered: Calculation of thermal loads and room temperatures design cooling load and annual simulation.

There are a number of regulation options that can be considered:. Abstract This standard serves to determine the cooling load, room air temperature and fdi room temperature for rooms of all vdi 2078 with and without air-conditioning, taking into account all relevant parameters influencing the thermal response of the room.

Not only that, but it also represents a solution that can easily be adapted to comply with the requirements of the new VDI guidelines. The stress from air flows can be vdi 2078 either statically with a fixed temperature or with respect vdi 2078 the outside temperature.

The latter allows 207 serving to demonstrate compliance with summertime insulation requirements. All reports have a simple structure vci contain brief legends in which abbreviations and terminology are explained.

Cooling Load as per VDI 2078

The report of the C. S calculation; these are generally available from the structural engineer or architect. Solar radiation can also be computed with a component inclination and albedo short-term reflection vsi that deviates from the VDI vdi 2078. For example, the planner can decide not to include direct sun radiation in his calculations or to deactivate all inner loads. VDI in turns requires that all surfaces in a room have a layer structure, to make it possible to deduce individual storage vdi 2078.

This standard serves to determine the cooling load, room air temperature and vdi 2078 room temperature for rooms of all types with and without air-conditioning, taking into account all relevant parameters influencing the thermal response of the room. Building components such as walls to neighbouring rooms can now be assigned different cooling load and heating load parameters in CAD.

VDI contains two different calculating procedures: Subdivision into zones In addition to the standard division into rooms, storeys, and buildings, a further grouping is now available: Illustration of thermal 278 below: Sun protection Shade Persons Lighting Machines Air flows Cooling of building components unregulated basic load cooling Controller characteristics technical installation data Profiles can of course be saved globally and used in further projects.

In addition to room air vdl, it is possible to base measurements on operative temperature i. The following reports are available: Ventilation Piping Sprinkler Electrical. Furthermore, an extension and completion of the compatible meteorological vdi 2078 has been achieved, the scope was extended to cover all types vdi 2078 buildings with vdi 2078 without air-conditioning, component cooling and window ventilation.

Cooling Load – C.A.T.S. Software

It is only necessary to input the number of persons and their degree of activity. The short cooling load calculation procedure as per VDI is performed by an interactive program with which the user can compute the cooling load of a room or building for predefined boundary conditions. Installation components affecting thermal response, such as mechanical or vdi 2078 ventilation and surface heating or cooling, are an integral vdi 2078 of the calculation method not vdi 2078 approximations any more.

Detailed and well laid out: For persons, the dry and wet loads are separated and then used automatically in the subsequent part of the program. The relative room air moisture 20778 derived from the humidity balance. It is therefore a great advantage of the new calculation that the building vdi 2078 do not require any layer data, such as thickness, specific heat capacity, density, thermal conductivity, or layer sequence, etc.

The method has been enhanced significantly with respect to the previous version, e. For cooling ceilings, it is possible to check if the dew point vdi 2078 not been reached. The combined outside temperature is calculated taking into account the vdl in the terrestrial vicinity.
