Scheme Discussion of Underground Water Cold and Heat Source Based on a Project Under the Double Carbon Background
Combined with the actual situation in a project that there is a large amount of pit water,the applicability and feasibility of four common air conditioning forms,namely central air transfer system(chiller+hot water boiler),underground water source heat pump air conditioning system,water source multi-line air conditioning system and air source multi-line air conditioning system,are compared and analyzed in this project.With the help of design and analysis software,load calculation,efficiency improve-ment and optimization of engine room,modeling and simulation of refrigeration operating conditions of the project building,and calculation of winter system operating costs based on heating operating load and operating hours;Through the analysis of dynamic annual value and carbon emission during operation,the results show that:under the premise of low grade energy available,the water source multi-line air conditioning system has obvious advantages in economy and carbon emission intensity.
