Description
Technical field
The present invention relates to application of solar energy and automatic control technology more particularly to temperature difference forced circulation solar water heating systems
To the mode of weather conditions automatic identification.
Background technique
Solar energy-thermal energy switch technology is used to building and provides annual required domestic hot-water's thermic load and in heating
When the Heating Load of Ji Suoxu, solar-heating heating system is just constituted；And it is used to building and provides needed for whole year
Domestic hot-water's thermic load and when cooling load needed for summer, just constitute solar-heating refrigeration system.Either will
Solar energy-thermal energy switch technology is used to freeze or heating, ideal operating mode, exactly meet needed for building it is cold,
Under the premise of thermic load and human body moderately require, solar energy is maximally utilised, reduce conventional energy to the maximum extent to reach
The purpose of energy-saving and emission-reduction is realized in the consumption in source to the maximum extent.In this type of application, collected by solar thermal collection system too
Sun can be the main energy sources of architecture refrigerating, heating and domestic hot-water's thermic load, and solar energy-thermal energy switch technology uses
Principal mode be exactly temperature difference forced circulation solar water heating system.
Temperature difference forced circulation solar water heating system is mainly followed by solar thermal collection system, solar energy thermal storage water tank, thermal-arrest
The composition such as ring pump and automatic control equipment, it is using the temperature difference of heat collector outlet and solar energy thermal storage water tank bottom water come domination set
The opening and closing of hot recycle pump constantly brings solar energy thermal storage water tank by the thermal energy that solar radiant energy is converted to for what heat collector was collected into
In, for being called when refrigeration, heating or domestic hot-water's energy.And collect the opening and closing of hot recycle pump, the length of working time is exactly to reality
When weather condition reflection.For same building building, heat needed for cooling capacity and heating needed for cooling is with one day
Middle different weather conditions and change, if the automatic control equipment in system can identify real-time weather conditions, and
According to recognition result to building provide different cooling cooling capacity or heating heat will to greatest extent utilize solar energy and building
Object energy-saving and emission-reduction provide new technological means.
Patent " active solar energy heating system autocontrol method " (ZL 2,011 1 0022444.1) is directed to solar energy
The operation of heat supply heating system gives a kind of mode of automatic control, and proposes and be divided into night, fine day on daytime for one day
With yin snowy day on daytime and knowledge method for distinguishing is carried out to it, mentioned with the weather conditions for enabling the system to different according to these to building
It can demand for different heating.But in practice in recent years, it is found by the applicant that the weather proposed in the patent in question is known
There are following significant deficiencies for other method: first is that the motion change reaction to the aerial floating clouds in day is too sensitive, often resulting in weather knowledge
Other result daytime fine day and daytime yin snowy day between rapid conversion, keep the operation of system unstable；Second is that one day is divided into
The method at night, fine day on daytime and yin snowy day on daytime is relatively rough, cause by night → daytime (daytime fine day or yin on daytime snow
It) and it is not gentle by the transition at daytime (daytime fine day or yin snowy day on daytime) → night, make the temperature fluctuation in these period rooms
It is larger, compromise the requirement to comfort.
Therefore, how to make the automatic identification of weather conditions more efficient and meet reality, make turn between different weather situation
Change more gentle to keep the work of system more steady, it has also become a technical problem urgently to be resolved.
