Economic and risk assessment of replacing water chiller units with liquid chlorine gasification waste heat utilization
液氯气化余冷利用场景下冷水机组替代的经济性与风险评估

摘要

在能源紧张与“双碳”目标驱动下，液氯气化余冷高效利用成为工业节能关键。传统冷水机组难以满足余冷回收需求，新型冷水机组替代的经济性与风险评估至关重要。通过构建成本收益模型与风险评估体系，分析替代方案的投资成本、运行收益、风险因素及应对策略。结果表明，虽然新型冷水机组初始投资较高，但长期运行可显著降低能耗与维护成本，具备经济可行性；同时需关注设备适配、技术风险等潜在问题，通过合理管控确保替代方案顺利实施。

Abstract

Driven by energy shortages and the 'dual carbon' goals, the efficient utilization of liquid chlorine gasification waste heat has become a key to industrial energy conservation. Traditional water chiller units struggle to meet the demands for waste heat recovery, making it crucial to assess the economic benefits and risks of replacing them with new models. By constructing a cost-benefit model and risk assessment system, this study analyzes the investment costs, operational benefits, risk factors, and response strategies of the replacement options. The results indicate that while the initial investment in new water chiller units is higher, they can significantly reduce energy consumption and maintenance costs over the long term, making them economically viable. Additionally, it is important to address potential issues such as equipment compatibility and technical risks, ensuring the smooth implementation of the replacement plan through effective management.
