Energy efficiency with demand controlled ventilation
We should save our planet for future generations. In the Building Industry we should construct our houses and offices as much energy efficient as possible to reduce CO2 emission.
The outcomes of the Glasgow climate change conference as well as the climate changes we experience around us every year, make clear that the negative effects of it on our planet should be tackled as soon as possible. One of the main topics is the reduction of CO2 emissions to avoid the warming up of the earth.
Did you know that the technical operation of buildings (heating, cooling and ventilation) currently takes up around 40% of global primary energy consumption and accounts for roughly a quarter of worldwide CO2 emissions?
Energy efficiency in buildings is thus the key to keep the energy consumption under control. Demand controlled ventilation is one of the possibilities to optimize the energy efficiency in buildings.
What does it mean demand controlled ventilation? Demand controlled ventilation means that the building automation system adjusts and minimizes the supply of outside air according to the specific requirements at that specific moment. In this way both air quality in the room and energy efficiency are optimized.
The aim is to have the ventilation system running in an optimal way for what concerns the user as well as energy efficiency.
How to measure the air quality? The air quality in a room can be measured either by a CO2 sensor or by an air quality sensor. But of course temperature, humidity and are also main parameters to create a healthy environment in the building.
When using a CO2 sensor the CO2 level will increase depending on the number of people in the room and the time period they stay in this room.
With an air quality sensor you measure the TVOC level (total volatile organic compounds). VOCs in indoor environments evaporate from substances such as cleaning products, adhesives, paints, new carpets, copiers and printers to building materials and furnishings. Next to that they are also emitted from humans and animals in their breath, sweat and directly from their skin.
All Sentera sensors have Modbus communication and can be easily combined with each other.
Moreover, when connecting to our Internet Gateway they can be connected to our Senteraweb. Via Senteraweb you can do data logging, you can consult or change parameters and if certain values are exceeded you can receive messages about this.
Energy savings through destratificationJust as winter is approaching, the current unprecedented energy prices are forcing us to use our energy even more consciously and efficiently. The most obvious measure is to lower the room temperature in our buildings. After all, if the thermostat is set a few degrees lower, a considerable saving will already be realized. However, in rooms with high ceilings, additional savings can be achieved through destratification.>>>
Temperature based air control in shipsThe design of the electronic speed controller GTE21-60-DM is based on years of experience in temperature control in greenhouses and other agricultural applications, combined with an innovative electronic technology. >>>
Global warming and energy efficiencyAlthough summer should be a time of relaxation, this summer seems to confront us with the harsh reality at an unprecedented pace. There is definitely something wrong with our climate and we need to act quickly. The extreme drought threatens to make the Rhine unnavigable and the capacity of some nuclear power plants is being reduced due to a lack of cooling water. In Spain, the use of air conditioning and heating is being restricted, while the war in Ukraine threatens to jeopardize energy supplies over the coming winter.>>>
Ventilation systems in the catering industrySummer has finally arrived and soon we will all be leaving for our favourite holiday destination. After an intensive day of vacation, we often like to put our feet under the table in an authentic local restaurant to enjoy the local specialties. As soon as the fragrant dishes appear on the table and stimulateour senses, we realize (as an HVAC professional) that the kitchen is most likely equipped with an efficient ventilation system.>>>
The advantages of a potentiometer with Modbus RTUPotentiometers with minimum and maximum limit, working from low to high speed or vice versa, with 0-10 volts, 0-20 mA or PWM output, infinitely adjustable or with adjustable steps (…) were already part of our assortment. Today we have expanded our potentiometer family with the SDP-M010 series that are equipped with Modbus RTU. As a result, not only are the settings available via the Modbus registers, but from SenteraWeb or your Building Management System you can also read the position of the potentiometer and even overwrite the output.>>>
