Hot-water heating system.
Background technique
Distributed energy technology is that the rapid new energy technology of domestic development, energy cascade utilization can mention significantly in recent years
High energy source utilization rate.The technology generates a large amount of waste heat in the process of running and is used to produce hot water.Due to its energy-efficient, green ring
The characteristics of guarantor, is applied to industrial park, larger office area, hospital, hotel more and more widely.
Due to the application characteristic of distributed energy technology, runing time section, i.e. waste heat generation time section and user's hot water
Usage time interval is not fully consistent, it usually needs under a large amount of waste heat that runing time section generates are stored by way of hot water
Come.Conventional method stores hot water frequently with large-scale open type boiler, then is supplied to by compression system and uses water spot.Skyscraper is to protect
It demonstrate,proves the economical operation feature of environmental protection and with water spot hot and cold water pressure balance, generallys use enclosed hot-water heating system, keep hot and cold water subregion consistent
And no longer separately increase compression system.In the case where waste heat continues supply situation, water temperature is able to maintain in suitable model in heat accumulation water pot
In enclosing, but when the waste heat energy stops for seasonable, with being extended with the water time, water total amount increases, and cold water moisturizing increases, and large size is closed
The decline of formula heat accumulation water pot leaving water temperature starts stand-by power source, but adjust when leaving water temperature, which is unable to satisfy user, to be required water temperature
The water temperature reaction time is long in large-scale enclosed heat accumulation water pot, influences user's comfort.If quickly mentioned only for stand-by power source
It rises water temperature and blindly increases the maximum power that stand-by power source is matched, or substantially increased to reduce the inadequate situation of leaving water temperature
Heat storage water tank capacity or the working method for directlying adopt open tank and compression system, although can solve above-mentioned water temperature out
Degree reduces, this problem of delay of response, but this is clearly uneconomic, select high-power heating equipment, large capacity water tank or
Adding compression system can make investment cost and operating cost be significantly increased, and not have economy.
In the related art, the waste heat energy and stand-by power source directly act in hot water storing tank, although stand-by power source can
Hot water is heated, but since storage tankage size is larger, causes stand-by power source energy consumption high, and short-term output water temperature is difficult to reach
To requirement, lead to water unstable out.Other in the related technology, the waste heat energy and stand-by power source directly act ons and hot water buffering
In tank, stand-by power source can quickly be heated water, but hot water buffering tankage size is smaller, and the waste heat energy less can only be converted into
Thermal energy storage is got off, waste heat energy waste, and user is with the water stage, stand-by power source can frequent start-stop, lead to energy waste, energy consumption
It is higher.
