    • A method for controlling the operation of an air-conditioning apparatus comprising devices (1, 2, 3) for supplying outdoor air (A) into a room (4), for removing indoor air (B) from the room, and for returning removed indoor air as return air (C) into the room; and devices (9, 16, 20) for adjusting the amounts of outdoor air, removed air, and return air. The adjusting devices are adjustable for controlling the mixing ratios between the air amounts according to desired air conditions to be created in the room. To achieve a greater controllability of the apparatus and to improve the accuracy of the mixing ratios, the outdoor air (A) and the return air (C) are passed into the room alternately, and the durations of the open periods of the adjusting devices are adjusted so that a desired mixing ratio is achieved between the amounts of outdoor and return air in the room. An air-conditioning apparatus developed for applying the method comprises operating means (22) arranged to open the adjusting devices (9, 20) of an outdoor air duct (5) and a return air duct (19) alternately for the duration of the open periods.

    • A method of providing a circulating air flow in a treatment space for a working area, whereby inlet air (A) is blown into the treatment space (1) to form a circulating air flow (A') in the treatment space, which flow provides an air curtain (A'') at an access opening (5) to the treatment space. In order to eliminate the disturbing influence of a workpiece (4) within the working area (3) on the circulating flow and to improve the working conditions, at least a part (B) of the circulating air flow (A') is deflected from the working area in such a way that the working area remains essentially within the circulating air flow. An arrangement for carrying out the method comprises a duct (7) formed in the treatment space (1) and passing the working area (3) for at least a part (B) of the circulating air flow.
    • 一种在工作区域的处理空间中设置循环空气流的方法,其中入口空气(A)吹入处理空间(1),以在处理空间中形成循环空气流(A'),该流程提供 在进入开口(5)处的空气幕(A“)到处理空间。 为了消除工作区域(3)内的工件(4)对循环流动的干扰影响并改善工作条件,循环空气流(A')的至少一部分(B)从 该工作区域使得工作区域基本上保持在循环空气流中。 用于执行该方法的装置包括形成在处理空间(1)中并通过工作区域(3)的管道(7),用于循环空气流的至少一部分(B)。

    • A method of introducing air into a room by passing supply air (A) into a distribution device (1) ending in the room (2) and by blowing the air from the distribution device through air supply openings (8, 9) into the room. In order to control the introduction of air even when the supply air is considerably warmer than the room air, the supply air is introduced into the distribution device selectively through two separate independent flow paths (4, 5) into the air supply openings, whereby the supply air is subjected to flow conditions required for heating at the air supply openings (8) of one flow path and correspondingly to flow conditions required for cooling at the air supply openings (9) of the other flow path. A distribution device carrying out the method comprises at least two separate alternative flow ducts (4, 5) for supply air, the flow ducts being provided with separate air supply openings (8, 9) which provide different flow conditions in the separate flow ducts.
    • 通过使供给空气(A)进入到房间(2)中的分配装置(1)中并将空气从分配装置通过供气开口(8,9)吹送到房间中而将空气引入室内的方法 。 为了控制空气的引入,即使在供气比室内空气温度高的情况下,供气通过两个独立的独立流路(4,5)选择性地导入分配装置,供给空气供给口, 供给空气受到在一个流路的供气开口(8)处的加热所需的流动条件,并且对应于在另一流路的供气开口(9)处冷却所需的流动条件。 执行该方法的分配装置包括用于供应空气的至少两个单独的替代流动管道(4,5),所述流动管道设置有在单独的流动管道中提供不同流动条件的单独的空气供应开口(8,9)。
