Rosenberg system regulation is one of advantages of Controller for air handling units Rosenberg
Rosenberg is the contact for project management, system identification, delivery, setup and agreement of
technical regulation installations. These installations embody the concept of "everything from one source"
and make us good at solving problems in ventilation technology. In this way any interface problems in the
planning process are avoided by planning the technical ventilation installation in-house and in the layout of the tailored technical regulation installation by close contact with our project team. With the use and combination of high-quality components, a functionally correct total installation is delivered. With this concept, the aim of maximum comfort of the installation and greatest comfort for minimised energy consumption is reached with certainty and economically.
Technical room air installations is the second of advantages of Controller for air handling units Rosenberg
RLT installations have the task of maintaining the condition of the room air regarding cleanliness, temperature and humidity within specific limits. The requirements made of the condition of room air can be very different depending on the type of room. In rooms in homes one is often content in the simplest case with window ventilation whereas for many industrial businesses, air conditioning systems are demanded that maintain any desired air quality constant with great accuracy. Between the two extremes there are countless stages with more or less comprehensive air treatment.
Classification of technical room air systems is the third of advantages of Controller for air handling units Rosenberg
Technical room air systems are mechanical ventilation systems that are constructed in such a way as to relieve rooms of the following problems:
Air pollution (smelly, harmful or dirt particles)
Excess heat/excessive cold
Unwanted substances
Technical room air systems definitions
Inlet air: is the air fed into the room
Outlet air: is the air going out of the room
Outside air: Is the air drawn in from the outside environment
Recirculated air: is the part of the outlet air that is fed back into the room. Recirculated air should only be used if the quality of the recirculated air corresponds to that of the intake air.
Exhaust air: is the air blown back out into the environment
Mixed air: is the mixture of outside air and recirculated air
Air removal systems: Air removal systems draw the air out of a room by means of fans and release it to the outside environment, whilst air flows in through openings from neighbouring rooms or the outside environment. Since the installations cause low pressure in the rooms where air is removed, they are particularly suitable for the prevention of spread of polluted air. They are therefore chiefly used in rooms with a high level of air pollution by gases, vapours, smells or high temperature such as e.g. kitchens, sanitary installations.
Air inlet systems: Air inlet systems, in contrast to air removal systems, draw in air from the outside environment and supply it to the rooms to be ventilated, with the effect that the excess air can escape to the environment or to the neighbouring rooms through doors, windows, other openings and unsealed gaps. Thus these systems cause a slightly high pressure in the room so the inward flow of unwanted air is prevented. In the winter it is necessary to heat the air to approximately room temperature by means of air heaters. This should prevent the cooling down of the room.
The use of air intake systems is mainly limited to rooms in which there is no heavy air pollution present
and where the air drawn in through windows and doors can easily escape into surrounding areas or the
environment e.g. offices, some factories, sales areas, exhibition halls.
Air intake and removal systems
In general it is useful to operate air intake and removal systems at the same time. By suitable measurement of the volume of air flow of outside air and exhaust air, suitable low or high pressure can be created as required in the rooms. Here the air intake and removal system represents the most suitable arrangement for almost all technical ventilation conditions e.g. halls of all kinds, theatres, cinemas, restaurants and bars, factory floors etc.
In particular, only with the controlled flow of inlet and outlet air will the effective use of heat recycling be
possible.
The catalogue is the forth of advantages of Controller for air handling units Rosenberg
This catalogue presents the Rosenberg control devices one after the other. There are three different
concepts available from which you can select according to the requirements of the technical ventilation
installation. The appliances shown in the following list are listed with the corresponding technical ventilation functions that are applicable. Here three different concepts are presented that differ in their layout.
Layout of the catalogue details:
The catalogue is divided into four sections. In the first section, the three control concepts are each presented on three double pages.
In the second section, with the help of ten block circuit diagrams the design of a technical ventilation installation is presented in the form of standardised symbols as described in DIN EN 12792 Part 1. An explanation of the symbols used can be found in the appendix.
The third section is dedicated to accessories. The components supplied by Rosenberg are described
here. The accessories shown in this section are not intended to be a complete listing of all technical control options. Here customer requirements are always of prime importance.
Procedure for the layout of a control system is the fifth of advantages of Controller for air handling units Rosenberg
1. Select a block circuit diagram according to the desired technical ventilation functions
2. Determine the motor type or the type of drive for the currents
3. Determine the fans of the inlet and outlet air fans.
4. Select the nearest current level
5. Put in the complete type designation in the place reserved for this
6. Tick required special functions
7. Determine the type of controller
- MSD ... - TR, RTE ... -TR / RTD ... -TR
- Airtronic B
- Airtronic D
8. Setting up the three-way mixing valve
What is included in the delivery package of the control system?
· Switch box completely wired with master switch, fuse, protection, terminal block and DDC controller.
· Comprehensive operation manual
· CAD switch diagram with wiring and terminal diagram.
· Distributed devices: duct sensors, room sensors, outside sensors, pressure difference monitors etc. depending on the arrangement.
· Frequency converter or EC controller for the specific type of fan operation. The frequency converter arrangement is always related to standard motors (400V output voltage). Frequency converters can also be selected that are not located in the Airtronic's switch box. The same also applies to the EC controllers.
· Continuous damper motor for the bypass damper with plate exchangers.
· 1 damper actuator for the outside damper i.e. if the connection of the outside air and exhaust air dampers is not possible, a further drive is required. For mixed air control a continuous drive should be used.
· The control setup and wiring are carried out during manufacture.
