【Abstract】 A compound refrigeration system combining natural cold sources and mechanical refrigeration is proposed, which is employed to meet the cooling requirements of ethylene glycol solution with normal temperature in the synthetic process of active pharmaceutical ingredients The research results show that both the cooling energy consumption and operating power consumption can be significantly reduced during winter and transition seasons, and therefore improve the economic benefits of the synthetic products of active pharmaceutical ingredients, which means the cooling technology comply with the national energy conservation and carbon reduction policies.更多还原
