| Say all:
Delta － PFS?Series' pressing a bad switch is the ACOL company is engaged in the central air condition development and the engineering construction over a long period of time of the staff member understand thoroughly currently many irregularities of the HVAC water system discharge control product but development of, it is an important series of the ACOL water current quantity control product, it has tightly packed of shape,outstanding function and have a competition of price is replace any form of the best choice of the type discharge switch.
Press the bad type discharge control principle:
Can pass to measure both endses, such as valve door and the bore plank...etc. to press to decline for the diagraph of the water current quantity, passing again to check the valve door and the bore knothole to press to decline and flowing the quantity curve can immediately get accurate discharge, the method that passes to press to decline gets the water side system and discharge that the discharge has already used extensively in the HVAC currently to measure appearance.Press the bad type water current quantity switch is the discharge control method of a kind of precision, it at the application lord in the HVAC system if carry on a control according to the resistance of the HVAC equipments and the curve of the discharge of, we know the HVAC equipments changes the hot machine(set tube type, hull tube type,tube the plank type and in common use plank type change a hot machine),water filter,the water pump and valve door etc. to equip all function curve of have the resistance and discharge, as long as examination press bad the switch both ends pass in and out water pressure bad, and with should equip in advance initial value to carry on a comparison, can with accurate control discharge.It is the discharge control switch to have the discharge control accurate,no longer increases resistance and requests and has no water current 擾 to move interference to the pipe line tube path again additionally to the system etc. characteristic, commendable generation any type the discharge switch of form Be the discharge control of the system of HVAC water, opposite can avoid the false discharge(actual current velocity very big, but mix in the water free spirit but actual discharge not big) that the water pump spirit eclipse cause in the type discharge switch, as a result can apply extensively small scaled breeze is cold in the usage the plank type change the hot machine,set tube type change the hot machine and the hull tube type change the hot machine greatly or make the amount of water current control to combine and have part to defend to freeze protective function in the water cold water machine set.
