Energy-saving renovation and benefit analysis for a general hospital in Guangzhou

Taking a general hospital in Guangzhou as an example, based on the current situation of the hospital’s gas steam boilers, the energy-saving renovation of the gas steam boiler is carried out by nearby dispersion replacement methods such as high-efficiency heat pumps, steam generators, electric hot water boilers. After the renovation, the hospital has been improved in terms of safety, greenness, cleanliness, high-efficiency, and smart energy consumption, and the safety and reliability of hot water, steam and heating in the hospital have also been greatly improved. The energy system is intelligently and flexibly regulated, the supply and the demand interact in real time, and the energy utilization efficiency is greatly improved. The annual saving of standard coal is 1 248.3 t, helping to achieve the “double carbon” goal. The annual NOxemission is reduced by 1.78 t, which significantly improves the surrounding environment. This paper can provide a reference for similar projects in the energy-saving renovation and benefit analysis of hospital gas steam boilers.
