Calculation Study of Cold and Heat Source Schemes Based on Mine Water in the Context of Dual Carbon Goals

摘要: 以湖州市某科研配套工程为例，对其进行全年逐时冷热负荷计算，得出不同负荷区间的运行时间，根据酒店设计冷热负荷进行空调冷热源方案选型。利用综合部分负荷性能系数(IPLV)的概念，并简化4种冷热源方案部分负荷时性能系数，以确定各方案不同负荷率下的COP，计算分析各种空调冷热源方案的初投资、运行费用、动态费用年值以及碳排放量。结果显示；水源多联机年运行费用约79.5万元，动态费用年值约122万元，碳排放量约493吨。从空调系统年运行费用、动态费用年值与碳排放量考虑，利用矿坑水的水源多联机系统更适合本工程，在具有水资源可以利用的条件下，水源多联机的具有更大的节能与减碳优势。

Abstract: Taking a scientific research support project in Huzhou City as an example, a year-round hourly calculation of the heating and cooling loads was conducted to determine the operating time for different load intervals. Based on the design heating and cooling loads of the project, the selection of HVAC heating and cooling source systems was made. By utilizing the concept of Integrated Part Load Value (IPLV) and simplifying the performance coefficient of the HVAC systems at partial loads, the coefficient of performance (COP) for each system was determined at different load rates. The initial investment, operating costs, dynamic annual costs, and carbon emissions of four HVAC heating and cooling source systems were calculated and analyzed. The results showed that the annual operating cost of the water-source multi-split system was approximately 795,000 yuan, with a dynamic annual cost of around 1.22 million yuan and carbon emissions of around 493 tons. Considering the annual operating cost, dynamic annual cost, and carbon emissions of the HVAC system, the water-source multi-split system utilizing mine water was found to be more suitable for this project. In conditions where water resources can be utilized, the water-source multi-split system has greater energy-saving and carbon reduction advantages.
