CYPEHVAC

Integrating duct analysis in CYPEHVAC Hydronics and program name change (CYPEHVAC)

As of version 2024.d, "CYPEHVAC Hydronics" (design of water distribution systems for air-conditioning) includes the analysis of ducts and, as a consequence, changes its name to "CYPEHVAC" (design of air-conditioning systems - heating, ventilation and air-conditioning).

Integrating the analysis of ducts in CYPEHVAC means that the program that in previous versions carried out the ductwork analysis (CYPEHVAC Ductwork) will not evolve from this version onwards. The latest available versions of CYPEHVAC Ductwork (2024.b) and CYPEHVAC Hydronics (2024.b) can still be downloaded from the BIMserver.center platform. However, we recommend that from now on, for designing air conditioning systems and analysing air ducts, CYPEHVAC should be used as this program will continue to evolve.

In order to be able to use all the CYPEHVAC features, the user license must have all the permissions included in "CYPEHVAC Hydronics" and "CYPEHVAC Ductwork". The user licence may only have some of the permissions to carry out the design of air conditioning systems (heating, ventilation and air conditioning) and may or may not have the permission to carry out the analysis of ducts. In this case, the program can be used for the design and analysis of the systems included in the user license.

The main change that users will notice in the application interface is the division of the "Installation" tab into the new "Water distribution" and "Air distribution" tabs. This division only affects the options available in the toolbar, as only those options that are required for each type of system are displayed. Both tabs share the display of the design model.

Among the improvements for the ductwork design in CYPEHVAC compared to CYPEHVAC Ductwork, we would like to highlight the following:

Integrating new ducted water-air-conditioning units (fan coils).
Automatically generated connections.
The ability to work with the actual dimensions of each unit.

Specific report of the results of the duct distribution with only the worst spans.

Display floor view templates in the 3D view

For 3D views defined within applications with a 3D working environment, the "Show selected templates in each floor view" option has been added. When activated, the templates visible in each of the floor views will be displayed in the 3D view in the dimension corresponding to these views.

Managing the visibility of templates in the view configuration window

As of version 2024.c, applications with a 3D working environment can manage the visibility of templates from the view configuration panel. For this purpose, the "DXF-DWG templates" tab has been added, where a list of all the templates imported into the project is displayed together with a checkbox to indicate which ones should be shown in the view.

Installation modes (professional, campus, evaluation, temporary license)

All CYPE programs can be installed in their different versions (Professional Version, Evaluation Version, Campus Version, Temporary License). In previous versions, users could only choose the type of version to be installed from the classic CYPE menu.

As of version 2024.a, the selection of version types has been implemented in all CYPE programs on the BIMserver.center platform.

As of version 2024.d, this selection can be made during the installation of all CYPE programs, regardless of where they are downloaded.

Installation in Polish

As of version 2024.b, CYPEHVAC can also be installed in Polish. This application can now be installed in the following languages:

Catalan
Spanish
French
English
Italian
Polish
Portuguese

Adding a pipe from an existing pipe

A new tool for drawing pipes in the circuit has been added, which allows the properties of an existing pipe to be copied when adding a new pipe.

To use this tool, click on its icon in the "Distribution" section of the toolbar. First, click on the existing pipe to be copied. The new pipe definition panel will appear, containing the properties of the existing copied pipe. Edit the panel if desired and click on "Accept" to start drawing the pipe.

Indoor hydraulic unit

A new unit has been added to the program: the hydraulic indoor unit. This is a commercial unit that brings together all the hydraulic accessories needed in domestic air-source heat pump systems, such as circulating pumps, expansion tanks or buffer tanks, in the same unit. In order to have access to these accessories, simply connect this unit between the air-to-water heat pump and the circuit inside the building.

To place a hydraulic indoor unit in the circuit, click on its icon in the "Fittings" section of the toolbar and place it on the drawing. To define its properties, a unit must be selected from the "Library". Once it has been correctly connected to the circuit, when analysing the system, the hydraulic indoor unit will display the results corresponding to the accessories it contains.

Loss of accumulated pressure

The calculation result of the "Loss of accumulated pressure" of the pipes has been included, both in the results displayed on the screen and in the results report.

After the calculation, when hovering the cursor over a pipe, the pipe’s data is displayed on the screen, and among the data, the result of the "Loss of accumulated pressure" will be shown. This value is the sum of the pressure losses in the elements located between the generator and the indicated pipe, which are both included.

Worst case path in terms of pressure loss

It is now possible to display the worst case path in terms of pressure loss. This path determines the necessary pressure increase in the circulation pump.

To view it, after the "Calculation", select the "Graphical analysis of the results" option in the toolbar and click on the new options in the pop-up dialogue box "Worst case path, cold water" or "Worst case path, hot water". This will cause the pipes that are part of this path in each circuit of the building to be highlighted in blue if they are cold water pipes or in red if they are hot water pipes.

New currency codes

In the help tool for filling in the currency code, within the general parameters of the project, the following references from ISO 4217 have been added:

EGP. Egyptian pound
KZT. Tengue
MYR. Malaysian ringgit
PHP. Philippine peso
SAR. Saudi riyal

Moving elements with the arrow keys

As of version 2024.b, applications with the "Element selection tool" (this tool was implemented in version 2021.e) have the ability to move the selected model components with the arrow keys on the keyboard. The elements shall be moved on the work plane of the active view in the direction of the arrow key. Whenever the arrow is pressed, the distance that is displaced is constant, so zooming will make it larger or smaller.

Improvements in the connection to BIMserver.center

Version 2024.b includes the following improvements and corrections to the connection of applications to the BIMserver.center platform:

After sharing a contribution, there is a delay before it becomes available in the BIMserver.center project. This could result in another application not having immediate access, even if the export was made from the same computer. Now applications can read contributions from the "File directory stored in local cache" before they are accessible in BIMserver.center.
It is now possible to export a contribution without an internet connection. When this occurs, a confirmation dialogue box will appear to inform users that if the contribution is exported, it cannot be shared in the BIMserver.center project. The contribution can be read in another application as long as it is on the same computer and linked to the same project. However, for the contribution to be available on the platform, users will need to "Share" it again with an internet connection.
The uploading process has been improved to allow larger files to be included.
An error that did not allow users to connect to the platform when the "AppData" system folder was not accessible has been fixed.
An error that showed the user as logged in when the session had already expired has been fixed.
The warning messages displayed when there is a problem in the communication with BIMserver.center have been improved.
Now, when creating a new project, the same default fields are used as in the BIMserver.center website.
