CD 30 ÷ 5207. The capacity control of the new modular chiller(1) Capacity adjustment of the system.Only the main unit can control the capacity output according to the temperature of total outputwater (Ts).1. Cooling capacity adjustmentPlease preset Ts (Ts=7,8,9,10,11,12℃). Ts is 7℃ in default.At first, the main unit will calculateδ1 (δ1=Ts-7), then adjust the capacity outputaccording to T(T=5,6,7℃)+δ1(T means the real temperature of total outlet water). Thedetail of cooling capacity adjustment is as following chart:TTsOFFCooling Regolazione capacity della adustment potenza di raffreddamento2. Heating capacity adjustmentPlease preset Ts (Ts=45,46,47,48,49,50℃), Ts is 45℃ in default.;At first, the mainunit will calculateδ2 =Ts-45,then adjust the capacity output according T(T=44,45,46,47,48℃)+δ2 (T means the real temperature of total outlet water).
