Abstract
(EN)
A refrigeration system, when a set evaporator water outlet temperature To is less than a daily minimum temperature Tmin, starts a cold water unit to cool a cooling pool; when the set evaporator water outlet temperature To is greater than a daily maximum temperature Tmax, starts a natural cooling source to cool the cooling pool; when Tmin ≤ To ≤ Tmax, if Ti≥To-a set value, starts the cold water unit to cool the cooling pool, and if Ti<To-the set value, starts the natural cooling source to cool the cooling pool. The refrigeration system not only satisfies the cooling requirements of the cooling pool, but also achieves the purpose of saving energy, reducing costs.
(FR)
L'invention concerne un système de réfrigération qui, lorsqu'une température de sortie d'eau d'évaporateur To est inférieure à une température minimale quotidienne Tmin, démarre une unité d'eau froide pour refroidir un bassin de refroidissement. Lorsque la température de sortie d'eau d'évaporateur To est supérieure à une température maximale quotidienne Tmax, il démarre une source de refroidissement naturel pour refroidir le bassin de refroidissement. Lorsque Tmin ≤ To ≤ Tmax, si Ti ≥ To - une valeur définie, il démarre l'unité d'eau froide pour refroidir le bassin de refroidissement, et si Ti < To - la valeur définie, il démarre la source de refroidissement naturel pour refroidir le bassin de refroidissement. Le système de réfrigération satisfait non seulement aux exigences de refroidissement du bassin de refroidissement, mais permet également d'économiser de l'énergie et de réduire les coûts.

一种制冷系统,通过在设定蒸发器出水温度To<当天最低气温Tmin时,启动冷水机组为冷却池降温;在设定蒸发器出水温度To>当天最高气温Tmax时,启动自然冷源为冷却池降温;在Tmin≤To≤Tmax时,若Ti≥To-设定值,则启动冷水机组为冷却池降温;若Ti<To-设定值,则启动自然冷源为冷却池降温。该制冷系统既满足了冷却池的降温需求,又达到节能的目的,降低了成本。
