Description
Technical field
The present invention relates to central hot water supply system and water circulation use field, especially a kind of Thermal Synthetic water circulation utilization system of Feng Ta power station.
Background technology
Comparatively large in hot water use amount, in the building relatively concentrated with water spot, people use central hot water supply system to carry out hot-water supply usually.It is large that it has water supply coverage, and hot water centralized system is standby, and Cemented filling is to advantages such as multiple water distribution points, and its thermal source is generally boiler, is heated by various fuel such as coal combustion, oil, natural gases.Also some central hot water supply systems are had to rely on solar energy equal energy source as thermal source.
Existing take boiler as thermal source, and the central hot water supply system being undertaken heating by various fuel such as coal combustion, oil, natural gases has consumption non-renewable energy resources, produces the shortcomings such as environmental pollution; The central hot water supply system being thermal source with solar energy equal energy source has the dependence of weather and environment comparatively large, cannot the weak point such as extensive use in the larger context.
The patent No. is 200810032462.6, name is called that the Chinese invention patent of " the solar construction integrated energy-saving hot-water heating system based on direct expanding solar heating pump " discloses a kind of solar energy that uses as the hot water supply system of thermal source, it is by being arranged at the throttling refrigeration effect of the cold-producing medium in sun set hot plate, make the operating temperature of sun set hot plate far below environment temperature, while absorption solar radiation, the heat in surrounding air can also be absorbed, enable solar water heating system in continuous rainfall sky, normally use in the bad weather of the solar radiation deficiencies such as winter.But in the bad weather of the solar radiation deficiencies such as continuous rainfall sky, winter, the temperature of its hot water provided, far below it provides the temperature of hot water in the weather of solar radiation abundance, fully can not meet the needs of people.Its basic reason is, although solar energy has cleanliness without any pollution, the advantage such as inexhaustible, solar energy has birth defect in application, and namely the dependence of solar energy to weather and environment is excessive.
In addition, some are also had using industrial exhaust heat, used heat etc. as the hot water supply system of thermal source.Its heat discharged when using cold water to absorb the work of some industrial equipments, cold water temperature raises becomes hot water; Also reduce the temperature during work of these industrial equipments simultaneously, avoid that its temperature is too high causes a series of problem.But its defect is the operation that its hot water supply relies on industrial equipment completely, if industrial equipment is out of service, this system is just unable to supply hot water, and resident just can not use hot water at any time.
The patent No. be 201120089015.1 Chinese utility model patent disclose a kind of heat energy recycling system of air compressor, it is by the first heat exchanger of being arranged in parallel and the second heat exchanger, make the first heat exchanger and the second heat exchanger alternately or simultaneously in running orderly carry out heat exchange, ensure that air compressor machine 24 hours uninterrupted normal operations can meet work need of production.Avoiding problems when only having a heat exchanger; heat exchanger breaks down and causes air compressor machine water temperature inside too high and must shut down; cannot be run without interruption the normal industrial production of impact for 24 hours, and heat energy recycling system also cannot the situation of 24 hours hot-water supplies.
But its hot water supply relies on the operation of air compressor machine completely, only in air compressor machine non-stop run in 24 hours ideally, this heat energy recycling system of air compressor could 24 hours hot-water supplies.When air compressor machine does not need to run without interruption for 24 hours, this heat energy recycling system of air compressor just cannot 24 hours hot-water supplies, just cannot meet the demand that people use hot water at any time.And although its temperature exporting water can regulate, but after setting, it can only export the hot water of determined temperature, and its hot water temperature needed of different people is different, even same people, the temperature of the hot water needed when processing different things in different is also diversified.Obviously, the hot water that this heat energy recycling system of air compressor exports cannot meet the diversified demand of people to hot water.
Simultaneously, the flow process that this heat energy recycling system of air compressor exports hot water is longer, speed is slower, it can only provide enough hot water to little people, and when the demand of people to hot water increases suddenly, this heat energy recycling system of air compressor can not provide enough hot water within the time needed.
