Abstract
The invention relates to a ventilator unit comprising a housing defining an air passage with a first port and a second port, a valve arranged in the air passage to control the air flow rate through the air passage, an actuator configured to operate the valve, and a controller configured to drive the actuator. The housing at the first port is configured to connect the first port to a duct outlet, and wherein the controller is configured to autonomously determine a drive signal to be sent to the actuator based on air measurement data.
Claims11
A ventilator unit configured to ventilate a space, the ventilator unit comprising:
- a housing defining an air passage with a first port and a second port, wherein the first port comprises a tube portion,
- an infinitely openable and closable valve arranged in the air passage to regulate the flow rate through the air passage,
- an actuator configured to operate the valve, and
- a controller configured to drive the actuator,
- wherein the tube portion of the first port is configured to connect the first port to a ventilation duct outlet or inlet, and the second port is configured to remain outside the ventilation duct outlet or inlet,
- and wherein the controller is configured to autonomously determine a drive signal to be sent to the actuator based on air measurement data in order to regulate the flow rate through the air passage, wherein flow of the air is through the first port to the second port or vice versa depending on a pressure difference between the space and the duct ventilation duct outlet or inlet.
