摘要： The method of operating a ventilation system that comprises an adjustable ventilation system device (1, 5) having at least two different set points, the selected set point of the ventilation system device (1, 5) affecting the air pressure in a first location (A) of the ventilation system, comprises the steps of operating the ventilation system with a first set point of said ventilation system device (1, 5) (101), measuring air pressure in the first location (A) by means of a first pressure sensor (2) while the ventilation system is operated with the first set point (102), operating the ventilation system with a second set point of said ventilation system device (1, 5) (103), measuring air pressure in the first location (A) by means of said first pressure sensor (2) while the ventilation system is operated with the second set point to detect the pressure change caused by the changing of the set point (104), and using the measured pressures to determine at least one value of at least one flow rate parameter representing the flow rate in the first location (A) (105).

摘要： A device (1) for controlling air flow, comprising a chamber (2) comprising an air inlet (3) and an air outlet (4), and an inner wall structure (30), arranged in the chamber, separating an inlet compartment (13) at said air inlet from an outlet compartment (14) at said air outlet (4). The inner wall structure comprises a first wall member (31) having a planar wall portion (32) comprising a layer of porous material which is permeable to air, and a valve mechanism (40), configured to move a cover member (41) over the first wall member to control a degree of exposure of said wall portion.

摘要： The invention relates to a filter element for a heat exchange system, said filter element being provided at an interface between an inlet branch of the heat exchange system via which an air stream is supplied and an airflow passage through a heat exchanger of the heat exchange system. The filter element comprises air filtering and distribution means for filtering the supplied air stream and distributing the supplied air stream over the area of the interface. The air filtering and distribution means has a corrugated, oblong shape having peaks and valleys extending in a longitudinal direction of the filter element, such as a first filtering material pleated in fanfold manner having longitudinal pleats.

摘要： To reduce uncomfortable feeling due to cold air and promote a rise in room temperature in an air conditioner that performs heating through a vapor compression refrigeration cycle. An indoor heat exchanger (16) exchanges heat between refrigerant and indoor air in the vapor compression refrigeration cycle. An indoor fan (31) is configured to change an air volume at a time of blowing out, into a room, conditioned air obtained through the heat exchange by the indoor heat exchanger. An air conditioner (1) performs, when starting heating, first cold air reduction control for restricting the air volume of the indoor fan (31) until a temperature of the indoor heat exchanger (16) reaches a first temperature, and second cold air reduction control for cancelling the air volume restriction at the indoor fan (31) when the temperature of the indoor heat exchanger (16) reaches a second temperature lower than the first temperature.

摘要： The present invention relates to a ventilation device (1), comprising an air flow passage (2) and a self-regulating valve (5) which is arranged in the air flow passage (2) so as to be tiltable and comprises a control limb (7) and a return limb (8) which are arranged on either side of the tilting point (6) at an angle with respect to each other and which are impingeable by the air flow in such a way that, at negative pressure at the outlet (4) with respect to the inlet (3) at increasing pressure difference between the inlet (3) and the outlet (4), said self-regulating valve (5) moves in a first direction of rotation (R) in order to restrict the air flow opening by means of the control limb (7) and, at positive pressure at the outlet (4) with respect to the inlet (3) at increasing pressure difference, moves in a second direction of rotation (S) in order to restrict the air flow opening by means of the return limb (8).
