The present invention relates to a ventilation device (1) comprising a first air duct (2) for air supply and a second air duct (3) for air supply. The first air duct (2) comprises a first outlet (4) for air flow and the second air duct (3) comprises a second outlet (5) for air flow, where the first outlet (4) is arranged to admit passage for a predefined amount of air per time unit (F-i). The second outlet (5) comprises a controllable choke device (6) that is arranged to either take a first position that admits passage for a predefined amount of air per time unit (F3) or a second position that does not admit passage of air. The ventilation device (1) comprises a control unit (7) and at least one detector (8, 9), where the control unit (7) is arranged to control the controllable choke device (6) in dependence of input data from said detector (8, 9) such that demand controlled ventilation is obtained.

摘要:
A multi-zoned HVAC system includes a control for independently determining the amount of airflow delivered to each zone within the HVAC system. The control determines nominal zone airflow and continuous fan airflow levels for each zone based upon a user selected fan airflow level and the relative size of each zone in the HVAC system. The control determines the desired system airflow for the entire system once the continuous fan airflow levels for each zone are determined. The HVAC system provides a continuous fan airflow to each zone independently of the continuous fan airflow delivered to any other zone and irrespective of the relative size difference of the zones.

Ein Gebäude (10), beispielsweise ein Hochhaus, umfaßt wenigstens einen mit der äußeren Umgebung (U) in Luftübertrittsverbindung stehenden Lüftungshauptkanal (16A, 16B, 16C), wenigstens einen Verteilerkanal (24), welcher zum einen mit dem wenigstens einen Lüftungshauptkanal (16A, 16B, 16C), und zum anderen mit Räumen (28) des Gebäudes in Luftübertrittsverbindung steht, wobei die Räume ihrerseits mit der äußeren Umgebung des Gebäudes in Luftübertrittsverbindung stehen. Erfindungsgemäß ist ferner eine dem wenigstens einen Lüftungshauptkanal (16A, 16B, 16C) zugeordnete Belüftungsvorrichtung (36A, 36B, 36C) vorgesehen zum Erzeugen oder/und Aufrechterhalten eines Belüftungsdrucks, dessen Wert (P1) größer ist als der Wert (P2) des in der äußeren Umgebung (U) herrschenden Drucks.
摘要:
The cooling air generated from the indoor unit (11) of an air conditioner is supplied into an air passageway (6) formed below the floor (2) on which an equipment (7) is disposed. The cooling air supplied to the air passageway (6) is guided into the equipment (7) through an opening (2b) made in the floor (2). The cooling air introduced into the equipment (7) is released into the free space (1) within the room. Further, the air stream released into the free space (1) of the room is partly introduced again into the equipment (7).
摘要:
A variable air volume ventilating system includes a fan volume modulator, for controlling a series terminal fan. A controller determines the proper fan motor speed, and generates a control signal which is transmitted to the fan modulator for varying the volume of the fan to be at least equal to the volume of the primary air available.
摘要:
An air conditioner according to the present invention comprises an air handling unit comprising a fan for supplying the air mixed the indoor air with the outdoor air to the indoor space and a heat exchanger for exchanging the mixed air blowing by the fan with the chilled water and a temperature sensor for sensing temperature, and a chiller which includes a compressor, a condenser, an expansion device and an evaporator and supplies the chilled water from the evaporator to the heat exchanger through a water pipe connecting the evaporator with the heat exchanger, wherein the chiller communicates with the air handling unit and sets a chilled water set temperature of the chilled water supplied from the evaporator to the heat exchanger according to the result sensed by the temperature sensor and changes the driving capacity of the compressor according the chilled water set temperature. Thus, it can prevent super-cooling and excessive dehumidification of the indoor space when a chilled water temperature of a heat-exchanger is too low. In addition, it can perform the sufficient cooling and dehumidification by the minimum electric consumption.
