Desktop Manager

The desktop manager is the basic program for every C.A.T.S. software user, and comprises the project manager and the report manager. The project manager is a complex tool which allows users to professionally manage projects, drawings and files, together with their respective addresses. Drawings can be opened and viewed using the project manager. Even comments can be added without any knowledge of CAD; indeed, an existing CAD system is not even required.

The new report manager makes it particularly simple to generate a report from the drawing. It is possible to load, view and print out the computed results or parts lists for a desired project, drawing or module, without actually having to open any drawings with a CAD program. The desktop manager is included in the update.

C.A.T.S. Commander

The new C.A.T.S. Commander is the comfortable user environment for the C.A.T.S. CAD applications and represents its central hub. It contains all pull-down menu commands, toolboxes and object pilots. All commands can be run from this central area and all building components selected.

For each application, the Commander contains a command area and a pilot area. The logical structure of the Commander's command area maps the work sequence of a project; it therefore represents an important aid to the user. The pilot area contains the building components, which are arranged in groups. Selecting the required group opens the respective building component libraries, which are then available for use.
By selecting multiple modules, it is possible to work simultaneously in several modules.

The so-called "basic commands", which jointly are required by all modules, are in a static area always available for the user. 

The dynamic structure of the Commander means that it can be used extremely flexibly. It can be fixed in position or placed wherever it is required. When in free-position mode, it is possible to select a degree of transparency. By using the automatic blank-out function, the Commander is only opened whenever it is required.
The new Commander means that C.A.T.S. software users now have a comfortable and highly attractive system of guidance prompts with which to work in each module.

SPRINKLER PROFESSIONAL

Application

With simple functions in C.A.T.S. Software Sprinkler professional the sprinkler system is drawn with the single-line method. After the calculation has been carried out the sprinkler net can be completed in 3D. Sprinkler professional meets all "demands for the calculation of sprinkler systems as per VdS 2092 or VdS CEA 4001, NFPA 13, NFPA 15, as well as deluge sprinkler system as per VdS 2109".

In the practical application, floor plans are first of all referenced. Each layer can also be edited in the referenced floor plan. The height is added to the respective floor plan at exactly the right point.

Due to the flexible layer management, it is possible to subdivide the entire sprinkler construction by storey. All sprinkler components, such as sprinklers, pipelines, pumps, valves, etc., are available in databases, By clicking on walls or entering a surface, the optimum sprinklers are automatically positioned in the plan in accordance with the VdS rules and NFPA standards, after selecting the sprinkler types, parameters, protection zones and heights.

Alternatively, the sprinklers can also be positioned in terms of reference points and edited with all standard AutoCAD functions, such as Copy, Move, etc.

In addition to the sprinkler types in the available database, it is also possible to create individually configured sprinklers.

Technical data and symbols are immediately provided for this purpose. The main and branch pipelines are added either individually or in groups. Existing
AutoCAD lines can be transformed into intelligent pipelines.

Additionally a large library with valves, components and pumps is available. For the complete pipeline network there are numerous test routines which check and then automatically correct any errors.

For calculations two methods are available which also allow for the calculation of e.g. foaming agents.

After the sprinklers and pipelines have been automatically numbered, the corresponding effective surfaces are created.

Once the direction of flow has been deduced, the calculation can begin. The calculation is performed in accordance with the pressure at the least effective sprinkler, the feed point or in terms of the average water impingement.

All results are clearly laid out and displayed immediately. All changes of the pipelines are associative and immediately realized in the drawing. Output is in VdS format, either as Ascii or directly in Excel.

Finally, the system components are extracted; the lists can be configured freely as required so that they give the user the required information. The module-universal collision test helps the user in coordinating the individual modules.

COOLING LOAD CALCULATION as per VDI 2078

Overview

The guideline VDI 2078 (Association of German Engineers) defines a method to calculate the cooling load on a daily progression basis. The cooling load for each hour of a day is calculated as a result of the values of the previous hours, which in turn depend on the thermal envelope of the building.

Furthermore, inner loads as people and outer loads as solar radiation define actions, which are turned into room reactions using a consecutive process, which leads to the cooling load for each hour.  This method complies with the ASHRAE approach, however, it gives you far more options to simulate and set up your system.

The C.A.T.S. cooling load calculator offers many simple inputting and outputting options.

Dynamic Procedure

The Navigator is the central C.A.T.S. Windows application in which the building data, the location, and all required building components are defined in a project file. The program supports the calculation of projects all over the world. Spatial geometries can also be imported from CAD. Relevant data is assigned to the respective room number directly in a dialogue.

Load profiles

In each project there are areas, which resemble each other in terms of their heating or cooling loads. By using specific load profiles, the data input requirements are considerably reduced. Variations can be calculated quickly and simply. All profiles can be set in all cases to all situations, 24 hours a day and 12 months in the year. This applies to Sun protection, Shade, People, Lighting, Machines, Air flows, Cooling of building components (unregulated basic load cooling), Controller characteristics (technical installation data)

Subdivision into zones

In addition to the standard division into rooms, stories, and buildings, a further grouping is now available  (for) zones. In these zones, the user can group individual rooms independently of stories; he can also perform zone calculations and observations. This makes it possible to map the various conditions that prevail within a project. Keywords: south side/ north side, staircases.

Internal loads

Regarding "internal loads", heat emission from people is calculated. It is only necessary to input the number of people and their degree of activity. For people, the sensible and latent loads are separated and then used automatically in the subsequent part of the program.

For lighting, it is possible to select single load recording or to use a global value per square meter or square foot. Solar radiation can also be computed with a component inclination and albedo (short-wave reflection factor).

Very light and very dark surfaces (e.g. due to water surfaces, forest, etc.) in the vicinity of the building component will result in an albedo (reflectivity) that deviates from the standard value of 0.2.
The combined outside temperature is calculated taking into account the reflections in the terrestrial vicinity. This means that parking spaces, water surfaces and aluminum facades located opposite, with deviating emission values, can be taken into consideration.
External shade caused by buildings located opposite is calculated.
The shade surfaces (soffit, escape balcony) can also have an angle of inclination that is not 90°. Shade is also taken into account for non-transparent external building components.
Neighboring room temperatures can either be determined statically or they can "oscillate" with adjustable references to outside or inside temperatures.

Regulating methods

Regulating methods have now been optimized and expanded. There are a number of regulation options that can be considered: Regulating power output, Regulating volume flow, Regulating volume flow for a displacement-air system, Incoming air temperature regulation, Incoming air temperature regulation for a displacement-air system.

In addition to room air temperature, it is possible to base measurements on operative temperature (i.e. perceived temperature).

The regulation functions can be equipped with installation limit values. The program calculates the data required for output, volume flow or incoming air temperature relative to the selected type of computation.
The calculation of volume flow and incoming air temperature takes into account the sensible and the latent load.  The outdoor air conditions are also computed. The relative room air moisture is derived from the humidity balance. For cooling ceilings, it is possible to check if the dew point has not been reached.
As regards power regulation, the regulated cooling and heating systems in a building component are input through the system's convective fraction.

Calculation and Simulations

The generated report has a consciously clear structure, as its aim is to help the user locate precisely the data he requires from the large amount available. The report of the C.A.T.S. cooling load program can be generated easily, using clear diagrams and graphs. All aspects of diagram presentation can be changed and the reaction values can also be incorporated. The user maintains control and retains a good overview; irregularities can be safely localized. The user can easily toggle between individual diagrams by month, without having to repeat the calculation.

Thermal comfort factor is becoming an increasingly important factor. The C.A.T.S. cooling load can determine the degree of sensed thermal comfort under all room conditions. It is then possible to localize deficits in thermal comfort and thereby minimize the percentage of dissatisfied persons.

Illustration of thermal comfort (below): it can be clearly seen that the percentage proportion of dissatisfied persons (PPD value) increases as soon as the temperature goes beyond the broad tolerance band (green).
To perform a simulation, there are a number of different calculation types that can be activated and deactivated, in order to recognize differences or to underline certain features. For example, the planner can decide not to include direct sun radiation in his calculations or to deactivate all inner loads. 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.

Detailed and well laid out: prints and reports

There are numerous reports that can be selected for securing and verifying the results of the computation. All diagrams that support it are displayed together with the report tables. All reports have a simple structure and contain brief legends in which abbreviations and terminology are explained.
According to requirements, room, zone, level or building reports can be produced. All reports can also be created as a PDF file.

The following reports are available:

• All input data
• Frequency with which current temperature is exceeded with reference to the outside temperature
• Frequency with which current temperature is exceeded with reference to the target inside temperature
• List of rooms showing the hours and months in which the maximum values for cooling and heating load were reached.
