Abstract
A refrigeration system, when a set evaporator water outlet temperature Tis less than a daily minimum temperature T, starts a cold water unit to cool a cooling pool; when the set evaporator water outlet temperature Tis greater than a daily maximum temperature T, starts a natural cooling source to cool the cooling pool; when T≤T≤T, if T≥T−a set value, starts the cold water unit to cool the cooling pool, and if T<T−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.
