Description
Technical field
The invention belongs to the technical field of agriculture production technology, relate to the booth technology in the agricultural production, more particularly, the present invention relates to a kind of solar energy photovoltaic electric-heating and become power accumulation of energy agricultural greenhouse.
Background technology
The greenhouse effect of booth provide the primary condition of modernized agricultural production for the agricultural cultivation of cold district or anti-season, but still have some guardian technique bottlenecks so far, are restricting the development of the modern industrialization of indoor agricultural, particularly at high and cold area.
Along with the day of global energy situation is becoming tight, energy-conservation and environmental protection becomes the focus that various countries, the world today pay close attention to.Traditional fire coal, gas heating mode and multiple permanent power electric heating heat-supplying mode etc. can't satisfy existing urban and rural buildings, the environmental protection of facility heat supply (warming up), energy-conservation requirement.
In order to improve utilization efficiency of energy and to control environment pollution; Emerge many heat supply new technologies and new model in recent years; For example utilize the heat supply heating technology of low ebb electricity, and the solar thermal collector that utilizes renewable energy resources and water source or air source heat pump also, the heat supply process etc. of connecting.
Yet still there is certain defective separately in existing new heat-supplying mode, or even insurmountable critical defect, directly affects the utilization and the development of renewable energy resources.

Solar thermal collector receive the area, round the clock, weather and sunshine in season acquisition rate change and the influence of factors such as energy storage carrying method; Cause the temperature of the hot water that provides unstable; Even adopt larger storage tank to carry out sensible heat energy storage water storage, do not reach the requirement of heat supply yet, can only be complementary indirectly; Efficiency of storage is lower, loses more than gain; Also bring simultaneously tens tons even go up the overweight load of kiloton water tank, antifreeze, freeze proof, split combines difficult with building, and the existence of various device can't overcome or the long-term technical bottleneck that does not overcome as yet;
Water resource heat pump or air source heat pump are subject to the effect of natural conditions of water source or air source, and particularly when low-temperature heating, high temperature refrigeration, its COP value does not reach and is difficult to reach " 1: 1 "; In addition, the automation control system more sophisticated, the integrated heat supply process of therefore designing and developing a new generation is very important.
At present,, can only the photoelectricity electric power storage be stored both at home and abroad through electric power storage, inversion transformation technique almost can not find under any situation that is applicable to DC load; Through twice conversion; Basicly stable direct current after transforming is become interchange, be connected to the grid again, serve as dummy load with electrical network.This twice conversion, the efficient of its conversion is low, can produce the loss up to 20%.
In addition, inversion system exists such as high pressure damage, island effect, technical problem such as be incorporated into the power networks synchronously.And must adopt electrochemical energy storage device (needing to adopt accumulator or ultracapacitor etc.) from the net electricity generation system, electric energy is converted into chemical energy stores.Not only the intervention of accumulator does not reduce application difficulty, on the contrary because of accumulator exists life-span and problem of environmental pollution, makes problem become more complicated.
In a word, be incorporated into the power networks at present and leave that the net electricity generation system exists all that cost is high, efficient is low, environmental protection hidden danger, use defective such as inconvenience.
