Description
Technical field
It is that one kind is applied to hospital the present invention relates to a kind of comprehensive hospital energy supplying system based on gas turbine and its application
, efficient, energy-conservation, economic hospital's energy supply comprehensive solution.
Background technology
Distributing-supplying-energy system refers to be distributed in user terminal, is main fuel using natural gas, passes through hot and cold, electric three
For etc. mode realize the cascade utilization of the energy, provide the user the integrated service of various energy resources, efficiency of energy utilization more than 70%,
And the modern energy method of supplying of energy supply is realized nearby in load center, it is the important way that High-efficiency Gas is utilized.
Distributing-supplying-energy system has high efficiency of energy utilization, the various, flexible adjustment of energy output, reduces the energy over long distances
The loss of conveying, can effectively raise security and the flexibility of using energy source, the effect with peak load shifting is to big electricity
Net forms effective supplement.
From the point of view of the development of the current distributed energy resource system of China, the research of distributed energy resource system is also in initial stage
Stage.But there is huge distributed energy resource system development potentiality in China.With economic development, the continuous of living standards of the people carries
Height, the major impetus that will be developed with the continuous growth of energy demand as distribution in China formula energy resource system.It is domestic at present distributed
Energy source use case is concentrated mainly on the places such as data center, industrial park, business district, factory, airport station and hospital.By
Beneficial to preferential policy support, distributed energy hospital application case is concentrated mainly on District of Shanghai, such as Shanghai Huangpu center
Hospital, Shanghai Minxing hospital, Shanghai First People's Hospital (Songjiang Nan Yuan) etc., but due to reasons such as Integrated Solution designs, it is most
Project is only capable of exporting a kind of energy, not strong with the coupling of energy feature with hospital, and system availability and utilization rate reduction fail to fill
The advantage of distributed energy is waved in distribution.
Hospital has cooling and heating load demand big, energization time length and load is relatively stable, unit area with can density compared with
It is high, the features such as the steady load phase is long, and obvious Seasonal Analysis is presented, be preferable distributed energy application places.
Under summer condition, hospital's major demands chilled water is used for the personnel zones of action such as ward, Outpatient Hall, and demand is big
And stably.Load height on daytime, the low situation of evening load, disease is presented in outpatient service region and medical worker's Administrative Area freezing Water l oad
Room region whole day load is relatively stable, is influenceed larger by temperature；Under winter condition, hospital major demands domestic hot-water, HVAC heat
Water etc., domestic hot-water's load fluctuation is larger, and moment morning and evening demand is larger, and night demand is smaller, and HVAC hot water load is relatively stable,
Fluctuation is smaller, is mainly easily influenceed by factors such as weather.
Hospital is different from general user, to the reliability requirement of the reliability of energy supply, especially supply of electric power compared with
Height, is typically designed using double circuit power supply system, sets diesel-driven generator, for key areas such as operating rooms, should also design certainly
Stand-by power source.
The traditional powered mode of Hospitals at Present relies primarily on gas fired-boiler and electricity to the demand of hot water, chilled water equal energy source
Air-conditioning is provided, and for the steam needed for meeting hospital's daily life, curative activity, domestic hot-water, HVAC hot water, hospital will consume greatly
The high-quality energy such as natural gas, electric energy are measured, while also increasing hospital's day-to-day operation cost.
Patent CN2687355Y discloses a kind of distribution of the equipment compositions such as gas turbine, lithium bromide chiller, dehumidifying unit
Formula energy supplying system, and the Distribution of Natural formula energy is coupled with renewable solar energy, improve energy utilization rate, but the party
Case fails to take into full account Various Seasonal to different cold and hot demands.Patent CN103775211A devise it is a kind of using gas turbine as
The active control type gas turbine distributed triple-generation system of core, is integrated with flue gas air mixer, gas turbine, remaining
The equipment such as thermal drivers subsystem, fume hot-water heat exchanger, improve system using combustion engine as core energy profit at part load
With efficiency and energy-saving efficiency, but the output of the program energy is single relatively, lack energy storage equipment, therefore be not particularly suited for hospital
Applied in conjunction.
From the point of view of the several hospital's distributed energy cases applied at present, system integration scheme be not it is highly desirable,
Actual energy-saving effect is not notable, and popularization and application of the distributed energy in hospital field are also have impact on to a certain extent.
Lack a kind of safe and reliable in industry, while efficiently feasible, it is possible to provide the various energy resources such as electric power, steam, hot water, chilled water,
It disclosure satisfy that distributing-supplying-energy system Integrated Solution of the hospital in Various Seasonal, not in the same time to different type workload demand.
The content of the invention
The present invention combines hospital energy feature and rule, provides cold and hot for gas fired-boiler in the prior art and electric air-conditioning
Water cost is high, Various Seasonal laws of use phase parity problem, big to high-quality energy resource consumption, proposes that a kind of structure is safe and efficient,
Energize reliability high, using the teaching of the invention it is possible to provide the various energy resources such as electric power, steam, hot water, chilled water export and adapt to hospital to cooling and heating load
Fluctuation, possesses the energy supplying system of mutual regulating power.
A kind of comprehensive hospital energy supplying system based on gas turbine is particularly provided, system includes gas turbine, remaining
Heat boiler, electric refrigerating machine, heat storage can, vapor-water heat exchanger, steam type lithium bromide absorption type cooling and heating unit.Preferably, combustion gas wheel
