    Abstract: Balancing a gas flow system comprising gas flow inlets and/or outlets by arranging a balancing (100) unit (10) at a respective gas flow inlet/outlet. Each balancing unit (10) comprises a gas flow measuring unit (11) and is wirelessly connected (102) with a system controller (20), which for each gas flow inlet/outlet is provided (103) with a desired gas flow and a measured gas flow when the balancing units (10) are in a first mode. Based on these flows, for each gas flow inlet/outlet a condition parameter is calculated (107), which are compared and a reference gas flow inlet/outlet identified (109). The gas flows through the gas flow inlets/outlets are adjusted (110), while the respective condition parameter and the condition parameter of the reference gas flow inlet/outlet are re-calculated at least once. The adjustment being performed by changing each balancing (10) unit from the first mode into a respective second, balanced mode, wherein the re-calculated condition parameter for a gas flow inlet/outlet is substantially the same as a re-calculated condition parameter of the reference gas flow inlet/outlet.

    Abstract: A heating system with wraparound heat exchanger is disclosed. The system includes a centrifugal fan that expels air radially into a plenum space. A heat exchanger tube is placed in the plenum space, thereby heating the air in the plenum space before it exits an assembly cabinet. The heat exchanger tube can have various configurations, including non-horizontal configurations so as to allow condensate to drain from the heat exchanger tubes.

    Abstract: 一种室内机、空调器及空调器控制的方法。室内机包括壳体(10),壳体(10)具有容纳腔,容纳腔设置有通风通道;蜗壳切换部可活动地设置于容纳腔内,以使蜗壳切换部具有第一位置和第二位置,蜗壳切换部位于第一位置时,蜗壳切换部与通风通道相配合形成进风通道,蜗壳切换部位于第二位置时,蜗壳切换部与通风通道相配合形成出风通道。通过设置蜗壳切换部改变室内机的通风通道的进风面积的大小,从而根据室内机的工作模式选择相应通风通道是出风通道还是进风通道。同时通过将蜗壳切换部设置成出风通道的方式,能够起到延长出风通道长度的作用,使得出风口处的风速更高,这样设置能够有效地增加了室内机的进风量和出风量,有效提高用户的使用体验。
