Abstract

The invention relates to a natural gas distribution type energy supply system of a hospital. The system comprises an internal combustion engine, a smoke and hot water type lithium bromide refrigerating and heating dual unit, a smoke and hot water heat exchanger, a hot water storage tank and a three-way regulating valve. The internal combustion engine is connected with a natural gas pipeline, a jacket water pipeline, a smoke pipeline and an intercooling water pipeline. The jacket water pipeline is further connected with the smoke and hot water type lithium bromide refrigerating and heating dual unit. The smoke pipeline is further connected with the smoke and hot water type lithium bromide refrigerating and heating dual unit and the smoke and hot water heat exchanger through the three-way regulating valve. The smoke and hot water heat exchanger is connected with the hot water storage tank. The intercooling water pipeline is further connected with the hot water storage tank. According to the natural gas distribution type energy supply system, different quantity demands of the hospital for sanitary hot water at different times are met through the hot water storage tank, and the problem that system operation is unstable due to great hot water load fluctuation is solved.

Description

technical field [0001] The invention relates to an energy supply system, in particular to a hospital natural gas distributed energy supply system. Background technique [0002] Natural gas distributed energy refers to the use of natural gas as fuel to realize the cascade utilization of energy through combined cooling, heating and power supply, etc. The comprehensive energy utilization efficiency is above 70%, and the modern energy supply method that realizes energy supply near the load center is natural gas. An important way to use it efficiently. This system is developed on the basis of the cogeneration system and is mainly used to meet various energy needs. It is a further expansion and expansion of the traditional cogeneration system in terms of application scale and application occasions. [0003] Distributed energy is a brand-new, efficient and environmentally friendly energy utilization method for primary energy. On the one hand, it comprehensively solves energy conv...
