Description
Technical field
The present invention relates to a kind of Heat Supply Engineering technology, especially relate to the system that a kind of focus utilization solar energy carries out central heating.
Background technology
Photo-thermal is as a kind of environmental protection, cheapness, the economic resources that are easy to get, is widely used in people's life and industrial production.Solar water heater mostly is single household's formula structure at present, its heating system is simple, but in use has following problem, and 1, because its heat collector of solar water heater and the supply tank of single household's formula all is installed on the roof, inconvenience not only is installed, and and security is also relatively poor.Though 2, the solar water heater of single household's formula is longer in many regional service time at sunshine, just is difficult to reach instructions for use to winter, must assist heating by the electric heater that is serially connected in the pipeline, use cost is higher.3, the solar heat device is owing to be subjected to regional influence bigger, especially weather is required to have certain adaptive capacity, and the heat pipe of thermal efficiency higher solar energy water heater is to adopt the vacuum glass tube at present, but because glass tube with vacuum pressure-bearing and resistance to frost are relatively poor, so when variations in temperature is big and in the transportation installation process, all reach fragile, especially in use, glass tube also can occur and burst to making the out of use problem of water heater, water heater working is unreliable.
And the solar energy that adopts vacuum glass tube heat pipe is concentrated the acquiring heat supply system, exists as a destruction and will make the out-of-work problem of whole system, and it is very unreliable to use.Secondly general heating system all is a unenclosed construction, and the cold water hydraulic pressure of heating system and hot water water are to have certain pressure reduction, thus can produce the fluctuation of pressure in the water supply process, and cause the cold and hot phenomenon of moment that supplies water.Simultaneously, it is also very inconvenient that hot and cold water is regulated, so be difficult for realizing constant pressure water supply, therefore must must adjust cold water hydraulic pressure and equate substantially with pressure of hot water, to satisfy instructions for use by other measure when heating system is installed and keep in repair.This just makes whole water system structure complicated, and increases operating cost.Moreover in the central heating system, only establish a supply tank, and be provided with electric heater in the supply tank, cross the water that can heat supply tank when hanging down in water temperature, to satisfy user's instructions for use by electric heater.This heating system is owing to can't expect second day and later weather, so the same day can occur under the situation of solar energy deficiency, water by electric heater heating supply tank, but it is fine everyday to second, because of the supply tank water temperature higher, and do not need solar energy to adopt heat, so this heating system can not make full use of solar energy, can increase heating system operating cost and use cost.
Summary of the invention,
It is reliable that technical problem to be solved by this invention provides a kind of heat supply, utilizes the heating of low ebb electricity auxiliary electrical to reduce use cost, and realize the photo-thermal central heating system of round-the-clock constant voltage constant temperature central heating water.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of photo-thermal central heating system, it is characterized in that: comprise the metal heat pipe flat-plate collector that is contained in a plurality of unit on the roof, storage tank and supply tank, the storage tank that communicates with running water filling pipe serial connection metal heat pipe flat-plate collector and formation are adopted thermal cycle; In be provided with electrical auxiliary heater supply tank be connected in series user's heating tube and user's return pipe respectively and constitute user's circulation of supplying water; Water in the storage tank after solar energy is fully adopted heat, and through a time period by pipeline with water supply with supply tank for the user for using; When the water temperature in supply tank is lower than electrical heating unlatching temperature, open the electrical auxiliary heater in the supply tank night, utilize the low ebb electricity that the water in the supply tank is heated.
Advantage after the invention process technique scheme is:
1, photo-thermal central heating system of the present invention adopts metal heat pipe flat-plate collector, its metal heat pipe not only has very high one-way heat conduction function, but also have stronger load performance and resistance to frost, guarantee that outdoor temperature also can operate as normal in the time of-25 ℃, therefore solved glass-vacuum tube because the stress that is produced in self characteristics and the processing, when variations in temperature is big and fragile in the transportation installation process, and after installing, what in use also can occur an a series of difficult problem such as bursts, adaptability power to weather is strong, not placed restrictions on by the area, the heating system reliable operation can prolong the service life of system effectively.
2, heating system of the present invention by mutual serial connection and sealing adopt heat circulating system and the heat supply circulatory system constitutes, it is simple in structure, the hydraulic pressure of metal heat pipe flat-plate collector, storage tank and supply tank is identical with tap water hydraulic in the whole system, solved cold water hydraulic pressure and hot water thermal hydraulic pressure in the central heating system owing to the problem of cold instantaneous heat of moment appears in pressure reduction, can realize that round-the-clock hot water or cold water's constant voltage unimpededly supplies with the user.
3, the present invention adopts storage tank and supply tank, and supplying water by two water tank serial connections obtains a time difference, promptly farthest makes full use of economic solar source, can guarantee the auxiliary heating of low ebb electricity again.When yesterday, photo-thermal was sufficient, then the water in supply tank today did not need to heat with auxiliary electrical again, directly is supplied to the user; When yesterday, photo-thermal was not enough, today, supply tank still used the hot water of deposit yesterday, have only when night, can be by the water in the low ebb electrical heating supply tank, guarantee that tomorrow, institute's heat supply water kept constant temperature, so circulation, and the calculating by the water yield, guarantee 24 hours constant temperature hot-water supplies of whole day, can reduce the operating cost of heating system greatly.
