In this paper , a variable blast air conditioning system based on vpvt control method is discussed . it is two stages master - slave bus control system . the variable static pressure smart coordinated control algorithm is realized by the master 本文研究了一種基于vpvt控制的變風量空調(diào)系統(tǒng),這是一種二級主從式總線控制系統(tǒng),主機實現(xiàn)了變靜壓智能協(xié)調(diào)控制, n臺從機分別對vav實現(xiàn)變風量的溫度間歇式pid批量控制。
In the more than twenty years developing history , the variable blast air conditioning systems go through three developing stages : constant static pressure constant temperature ( cpct ) control method ; constant static pressure variable temperature ( cpvt ) control method ; variable static pressure variable temperature ( vpvt ) control method 變風量空調(diào)系統(tǒng)在二十多年的發(fā)展歷史中,經(jīng)歷了三個發(fā)展階段:即定靜壓定溫度控制法( cpct ) ,定靜壓變溫度控制法( cpvt ) ,變靜壓變溫度法控制( vpvt ) 。
After putting the 150 mg / m3 electrostatic needle filtration fabric on the home air condition , the air condition ' s purifying efficiency can get to 71 . 0 % ~ 73 . 6 % and the resistance is 56 ~ 92pa which is a little higher . and the blast air ' s speed becomes lower and the quality of ventilation becomes less which affect the air condition ' s work 柜式家用空調(diào)器上使用150g m3的針刺荷電纖維后,過濾pm _ ( 10 )的效果顯著,過濾效率可以達到71 . 0 73 . 6 ;阻力稍微偏高,達到56 92pa ,送風口風速降低30 ,通風量減少,延遲了空調(diào)制冷時間,制冷效果沒有原來好,使用時應(yīng)注意。
