Method and system for controlling ventilation in a building
First Claim
1. A method for controlling ventilation of an indoor area of a building, comprising the steps of:
- ventilating the indoor area by means of mechanical ventilation and natural ventilation according to a ventilation mode selected among a plurality of ventilation modes, a set of adjustable control parameters, and at least one measurement value from a sensor, wherein;
each ventilation mode is associated with the set of adjustable control parameters, each adjustable control parameter having an adjustable value selected among a group of mode dependent adjustable values,each ventilation mode is associated with a set of fixed control parameters each having a mode dependent fixed value, wherein at least one of the mode dependent fixed values of at least one of the plurality of ventilation modes is different from at least one of the mode dependent fixed values of another of the plurality of ventilation modes; and
controlling the mechanical ventilation and the natural ventilation by comparing the measurement value from the sensor with a corresponding value of the control parameters of the ventilation mode such that a desired indoor climate defined by the ventilation is obtained and wherein the ventilation modes define different indoor temperature set points.

Abstract
A method and a system for controlling ventilation of an indoor area of a building, comprising the steps of: ventilating the indoor area by means of mechanical ventilation and natural ventilation according to a ventilation mode selected among a plurality of ventilation modes, a set of adjustable control parameters (31; 32; 33; 34; 35) and at least one measurement value from a sensor, wherein each ventilation mode is associated with the set of adjustable control parameters (31; 32; 33; 34; 35), each having an adjustable value selected among a group of mode dependent adjustable values, and/or a set of fixed control parameters (34) each having a mode dependent fixed value, and controlling the mechanical ventilation and the natural ventilation by comparing the measurement value from the sensor with a corresponding value of the control parameters of the ventilation mode such that a desired indoor climate defined by the ventilation mode is obtained.
