Description
Technical field
The present invention relates to solar water heater field, be specifically related to the embedded optically focused phase-transition heat-storage non-water tank solar water device of balcony integration.
Background technology
, climatic deterioration nervous in global energy, today of serious threat economic development and people's life health, countries in the world all seeking new energy substitution strategy, obtain superiority in the hope of sustainable development with in development.Along with the continuous reinforcement of people's energy-conserving and environment-protective consciousness, solar energy, with its safety, energy-saving and environmental protection, health, economy, waits significant advantage, has won rapidly the favor of consumers in general.Solar energy is converted into heat energy by solar water heater, and water is heated to high-temperature from low temperature, uses to meet the hot water of people in life, production.China is since the seventies in last century introduces the sample pipe of all-glass vacuum thermal-collecting tube, in the development of solar energy industry, the heat utilization switch technology of solar water heater has the evolution of more than 40 year, in this evolution in more than 40 years, though output is advanced by leaps and bounds, technical performance is not ripe perfect, because the energy-conservation of solar water heater and the increasing consumer of convenience have selected solar water heater.But but there is no too much progress at the technical elements of water heater, the state of the art such as structure, performance of product itself then remains original style and features substantially, progress is only only limitted to the improvement of assembling the scopes such as insulation and production technology aspect, and technology, structure and performance do not have revolutionary breakthrough.Current solar water heater mainly contains following deficiency, and Solar use is not enough, and water temperature is lower, for shell and tube solar water heater, owing to there is space between each solar water heater glass tube, the solar energy at this place is not applied well, and water temperature is lower.Solar water heater resists cold problem, because the water tank of existing water heater and water pipe have water all the time, winter, the pipe that solar water heater contacts with water, valve device ice cold rise act under very easily cause frost crack pipe, defective valve cannot use, even damage, and the chain reaction caused thus, a large amount of running water is excessive; Use the undesirable also easy breaking out of fire of heating tape antifreezing effect.Solar water heater is difficult to safe overwintering winter, and its basic reason is caused by solar water heater structure defect.The hygienic issues of solar water heater, water in solar water heater water tank just starts to supplement before not using up, part water is accumulated in water-heater water tank for a long time become " stagnant water ", do not flow and cause water body self water quality deterioration, and, solar water heater is once and again heating " stagnant water " especially, under " stagnant water " hot soak condition, produce the nitrite that some are carcinogenic, consumption of a specified duration makes it concentrate further, again increase the weight of water quality deterioration, cause the water of solar water heater not only can not drink, have a bath exactly, wash dish also very inadequate, washing clothes can only be used for, seriously limit the range of application of solar water heater.The installation question of solar water heater, solar water heater is installed and is mainly arranged on top of building, difficulty of construction is large, install insecure, often have solar water heater to be blown off accident to occur, and safeguard constant and be subject to thunderbolt etc., be arranged on roof simultaneously and building appearance inharmonious, affect building attractive in appearance; Also balcony wall-hanging solar water heater is had, wall-hanging solar water heater installs the large A-frame mainly with tilting as installation foundation, want construction of ascending a height outside wall, difficulty of construction is large, and safeguard very difficult, owing to being provided with inclination angle, protrude outside building wall, inharmonious with original building outward appearance, impact building is attractive in appearance; Also a small amount of balcony solar water heater is had, adopt and erect installation in balcony face, one is that vacuum tube water heater erects installation, when vacuum tube water heater is erect and is installed, greatly reduce the vertical incidence light of solar energy, reduce the Heat-collecting effect of solar water heater, and the touching being easily subject to household and child is installed at balcony, use dangerous; Another kind is that flat water heater is vertically installed, collecting efficiency is lower, and due to flat water heater face coat be black or navy blue, surround balcony surrounding tone very inharmonious, affect building attractive in appearance, and balcony balustrade function can not be taken into account, also in addition balcony balustrade to be installed, cause investment waste, cost is high, should not promote.It is urgently to be resolved hurrily to there are problems in above solar water heater application.
