CYPETHERM EPlus

The Vaillant "aroTHERM" aerothermal systems catalogue has been incorporated. The Vaillant logo appears in the Aerothermal-type water air-conditioning systems. In the panel that opens when the logo is clicked on, users can choose between the different "aroTHERM" compact equipment models and add the "uniTOWER” hydaulic module.

As occurs with other aerothermal systems, users can choose whether the system will be used only for heating or also for cooling. Users must also specify the working temperature conditions of the installation and its operating mode during the year.

The Vaillant "aroTHERM" compact aerothermal equipment have also been incorporated into the "DHW Systems" panel.

As of the 2019.h version, CYPETHERM programs with the EnergyPlusTM analysis engine (CYPETHERM EPlus and CYPETHERM RECS Plus), can import aerothermal equipment from DAIKIN’s monobloc, bibloc and HT series that have been defined in the BIM project using Open BIM DAIKIN.

Users can define the temperature margin to calculate the out of setpoint hours. This can be done in the "Design options" panel (Analysis tab > Design options button or Analysis button).

In the simulation, the hours in which the air temperature of the building spaces lies outside the heating or cooling setpoint temperature range are counted as hours out of setpoint, with a margin higher than the indicated values. In previous versions, this margin was fixed and with a value of 0.2 ºC.

As of the 2019.h version of CYPETHERM programs with the EnergyPlusTManalysis engine (CYPETHERM EPlus and CYPETHERM RECS Plus), users can define more than one water-cooled water chiller system in the same building. It is also possible to define several water air conditioning systems in the building if, additionally, water-cooled systems have been defined for the chiller.

Furthermore, as of the 2019.h version, users can define any number of production equipment within the water air conditioning and condensation systems. In previous versions, there was a maximum limit of 10 units.

The 2019.h version of CYPETHERM programs with the EnergyPlusTM analysis engine (CYPETHERM EPlus and CYPETHERM RECS Plus) uses the new 9.1 version of the engine, published on 27 March 2019.

Two new example projects have been added:

  • Restaurant
    It consists of an isolated place for restaurant use whose room is air-conditioned using a compact roof unit that distributes the air through ducts.
  • Residential Row Houses
    Represents an urbanisation of residential homes, with individual heating, air conditioning and solar DHW installations.

Thermal envelope of the building in GLTF standard format

As of the 2019.g version, "CYPETHERM EPlus", "CYPETHERM HE Plus" and "CYPETHERM RECS Plus" export two independent GLTF files (attached to the IFC) with the thermal information of the building envelope to the BIM project located on the BIMserver.center platform. Each GLTF file allows users to view the data in a different way in any viewer that interprets the GLTF standard format (AUTODESK Viewer, glTF Viewer, BIMserver.center web viewer...):

  • Thermal model, by element
    The complete construction solutions used in the building are displayed, as well as their properties (reference, thickness and thermal resistance).
  • Thermal model, by layers
    The individual layers that make up each construction solution together with their properties (reference, thickness and thermal resistance) are displayed.

Export results to the Open BIM project

As of the 2019.g version, CYPETHERM programs with the EnergyPlus™ analysis engine (CYPETHERM EPlus, CYPETHERM HE Plus and CYPETHERM RECS Plus) can export the results reports they generate to the Open BIM project to which they are linked.

To do so, the Export button has been added in the "Results" tab. As with other programs included in the Open BIM workflow, this export generates a file with IFC format that is included in the BIM project, located on the BIMserver.center platform (other programs that also generate graphic documentation will include other "IFC" " in the project). The IFC files of CYPETHERM with the EnergyPlus™ analysis engine contains the PDF files corresponding to the results lists. These PDF files will be accessible from the BIMserver.center platform by any member of the BIM project team that has the appropriate role.

Import VRF equipment from Open BIM FUJITSU

As of the 2019.g version, CYPETHERM programs with the EnergyPlus™ engine (CYPETHERM EPlus, CYPETHERM HE Plus and CYPETHERM RECS Plus) can import the Fujitsu "VRF Airstage" equipment that have been defined in the Open BIM project using Open BIM FUJITSU.

Import data from Open BIM TOSHIBA

As of the 2019.g version, CYPETHERM programs with EnergyPlus™ engine (CYPETHERM EPlus, CYPETHERM HE Plus and CYPETHERM RECS Plus) import new data from the air conditioning systems defined in Open BIM TOSHIBA. Specifically, they import pipe lengths and the installation dimensions of the 1x1 split equipment with distribution by ducts, and the outlet water temperatures defined in the aerothermal equipment.

A new tool has been implemented that allows users to edit the elements of the same type that have been defined in the project. It is a multiple editing tool and works with an assistant that starts by pressing the “Multiple edit” button located in the upper toolbar. The "Multiple precinct editing" button that appeared in previous versions has been integrated in this new tool.

The multiple editing assistant allows users to modify the properties of the zones, spaces, terminal units and of certain elements defined in the library, using the buttons at the top of the window. The assistant will only modify the properties chosen by users of the elements selected in the assistant itself (Elements that have been introduced-Zones, Spaces, and Terminal Units-, or Library elements- Spaces, Doors, Glazed openings, and Skylights).

The multiple editing assistant also allows users to delete zones and terminal units.

CYPETHERM programs with the EnergyPlusTM analysis engine, CYPETHERM EPlus and CYPETHERM RECS Plus, can import the equipment and pipes introduced in "Open BIM DAIKIN" (implemented in this version) if they are connected to a BIM project located on the BIMserver.center platform that contains this information.

In the "Calculation" tab, within "Complementary reports", the report "Linear thermal bridges" has been implemented. This report includes the total length and the linear thermal transmittance (value Ψ) of the thermal bridges defined in the project.

For each space, the walls and slabs that limit it are defined. When one of these elements is an interior partition, i.e., a partition or a floor between floors, the space that lies on the other sidemust be defined. Until now, users could choose an adjacent room amongst those defined in the project or leave this field empty, which implied that the partition is adiabatic, that is, no heat is lost or gained through it.

In the 2019.f version, the definition of the existing options is explicitly indicated in "Adjacentspace" and the new option "Unknown space" has been added. This option allows users to more adequately define the partitions that are next to spaces of other buildings, whose use is unknown and have not been defined in the project. For design purposes, this unknown space will have the outside temperature.

The option "External air intake" has been addedfor "Variable air flow" and "Double duct"air conditioning systems. Free cooling, and sensitive or enthalpy heat recovery energy saving strategies can be applied when air can be taken from outside using these systems.

Adding an air conditioning system with external air intake implies that the air impulse terminal units connected to the system will perform the ventilation of the zones where they are defined. Therefore, for these areas, the Ventilation optionmust be chosenvia the air conditioning system. This option is activated automatically when this type of system is created using the assistant.
