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.
