This ram air is generated by the aircraft flight speed and is driven into the primary heat exchanger by a special scoop. This scoop has often a variable geometry electrically driven depending on of the flight phase (take off, cruise, etc.). 5 th step :

正循环(热机循环) 特征 (1)P-V图中循环过程沿顺时D针方向进行。 (2)工质经一循环从高温热源吸热Q1(>0)在低温热源放热Q2(绝对值),对外输出净功A(>0)

空调工程有三个重要术语,即得热量、冷负荷与制冷量。三者在数值上虽相近,而且 相互紧密关联,但其概念却截然不同。 得热量与冷负荷 得热量是指在某一时刻进入房间的总热量值,该热量为稳定得热与瞬变得热之总和,即 包括由于室内外温差引起的传热量,太阳辐射进入房间的热量,照明、人员和设备散发于 房间内的热量等
