Dynamic Airflow Balancing is a radically new way to control airflow inside a building.
We like to think of it as a team of gremlins running around in your duct work, constantly adjusting airflow in each room to maintain the desired temperature.
Of course as much fun as it would be to control air with gremlins, it's just not practical. Especially if they get wet. So we're using the power of the Internet of Things to control the "weather" inside your office.
Introducing, The Internet of Air.
75F is utilizing the power of cloud computing to solve an age old problem with HVAC systems in light commercial buildings. Traditional systems rely on a single thermostat to receive feedback on the heating and cooling demands required by the space, but the temperature desired by the occupant will vary greatly throughout the building - and even room by room.
Smart thermostats are growing in popularity because of benefits like scheduling setbacks to save energy or remote monitoring via wifi. External sensors are used to gather more information about the different temperatures throughout a building.
But the questions remains, what can be done about temperature imbalance? The answer to this question is driving the 75F team to develop breakthrough technology that simplifies operational complexity and makes the product intuitive.
The 75F approach treats each room as a personal micro-zone and calculates the heat loads they require every minute of the day. This is where the power of cloud computing and the internet of things comes in - sensors collect data to generate a thermal model of the building. An algorithm takes a myriad of variables into account and calculates the thermal requirements of each room. Knowledge is power and this data fuels 75F's Dynamic Balancing System.
Buildings are dynamic. The heat load required by each room will vary by time of day, amount of people in the room, the weather outside, etc. Many HVAC systems cannot collectively account for these variables to make intelligent and orchestrated adjustments that both increase comfort and save energy.
When an HVAC system is first installed in a building, the loads for each space are calculated and the dampers are manually adjusted to reflect these calculations - which is known as commissioning a building. These adjustments are based on a "design day" the engineer deemed suitable for the space. When the external environment (weather, time of day, people in a room, humidity, etc.) match the scenario the engineer balanced the system for, things are great! But when any single variable deviates from the "design day", there is an imbalance. And with an imbalance follows inefficiency and discomfort.
To fix this all to common problem, 75F installs a Smart Damper at each diffuser in the building, that controls how much air flows into each room.
As an example, when a room on the east side of the building receives sun in the morning it will require more AC than the west side. The dampers adjust accordingly to deliver cold air where it's needed to keep everyone comfortable. With many current systems, either east side people sweat all morning or west side people freeze.
A very important distinction between 75F and other HVAC systems is how we utilize the Internet of Things. All sensors and Smart Dampers are connected to the cloud and work together to be as efficient as possible. Sending air where it is needed, when it is needed. No more and no less. The harmony between predictive intelligence and hardware prevents large temperature swings, making your office efficient and comfortable.
