Program design and calculation of air conditioning VRF

«Dva Oblaka. VRF air conditioning» - an online program for the design and calculation of VRF air conditioning systems. The program works in the browser and does not require installation of any additional programs. At the same time, direct download of architectural projects of AutoCAD in DWG and DXF formats to the program and unloading of projects executed in it back to DXF is supported. This allows AutoCAD designers to quickly switch to using the «Dva Oblaka. VRF air conditioning»

Architectural background

When creating a project, the Two Clouds program offers to load an architectural underlay with all project floors in DWG, DXF, PNG and other common formats, adjust the scale, specify the floors and the floor alignment point. According to the specified data, the program creates project floors, and you can begin to design VRF air conditioning systems. With any changes in architecture, you can at any time replace the architectural substrate of any floor, while retaining all the HVAC systems that you have designed in the program.

VRF 2D air conditioning design

The program allows you to design VRF air conditioning systems in 2D-view on top of the architectural substrate. Choose diameters of freonoprovod or draw freonoprovoda of any size for the subsequent automatic selection of diameters. Choose the height of the freon duct drawing and use the auto connect function to automatically connect the freon ducts at different heights. Automatically track collisions during design. For ease of design at any time, specify the angle of rotation of the project.

View project in 3D

Switch to 3D mode and back by pressing one button directly in the browser. Choose any objects in 3D, zoom in and out, move randomly around the project. In addition to the automatic collision tracking feature, check for no collisions directly in 3D. Go to the objects in the 2D plan by selecting them in 3D. Take screenshots of the project to provide 3D visualizations to your customers. Choose which systems to display on 3D, and whether to display other HVAC systems on 3D.

Inserting equipment into the project

Calculate directly in the program or insert into the project the external and internal blocks calculated by the manufacturers for your requests. The inserted equipment has the correct overall and connecting dimensions from the manufacturers and is ready for quick connection of the freon ducts. Also, the equipment immediately has all the parameters necessary for the subsequent calculation.

Calculation of air conditioning VRF

After the system is assembled, start the calculation of the diameters of the freon lines and the sizes of the refnets. Before calculating the system, a check is made by the manufacturer for restrictions on the maximum length of the freon duct to the farthest inner block, and restrictions on the maximum height differences between the outer and inner blocks of the system.

Uploading results

Upload VRF air conditioning plans to AutoCAD in DXF format and / or PDF format and overlay them on the original architectural plans. Unload axonometry of any system. Both on the plan and on axonometry, the program automatically arranges native AutoCAD callouts, which you can further move and edit in AutoCAD. The Prorgamma Two Clouds automatically arranges callouts so that they do not overlap each other. Download the equipment specification for the entire project in XLS format.
