Abstract
The invention relates to a greenhouse energy-saving heat insulation system, which mainly comprises a heat storage device, a solar heater collector, a soil heating device, a heater radiator and the like. Through adopting methods of construction, selection, arrangement, connection, valve control and the like on each device, three circulation loops are built. The system absorbs and stores solar energy in daytime for carrying out heat collection circulation, and the stored energy is released into a greenhouse at night for heat radiation circulation. The circulations work in the whole day, and in addition, the electricity is not consumed in most time. For links requiring electricity, the effects of short electricity consumption time and little use equipment are realized. The greenhouse energy-saving heat insulation system has the beneficial effect that the electric power cost is greatly reduced on the premise of heat insulation.
Description
Technical field
The present invention relates to the energy-conservation warming system of a kind of agricultural greenhouse.
Background technology
North booth temperature at night in winter is too low, is unfavorable for the growth of plant.At present for the ubiquitous problem of solar greenhouse of winter warming be: operating cost is high, some systems are for increasing warming effect, rely on the even multiple water pumps of water pump as circulation power, 24 hour operation, not only power cost is very high, and causes to the depending on unduly of electric power, even run into temporary transient power failure, also can lose heat-preserving function, increase the risk of freeze injury.Now in the urgent need to finding a kind of good warmth retention effect, the energy-conservation warming technology of the booth of power saving very again, reduces cost, avoids risk.
Summary of the invention
The object of this invention is to provide the energy-conservation warming system of a kind of booth, solve the low and high problem of current warming system operating cost of northern booth temperature at night in winter.
The technical problem to be solved in the present invention is: eliminate current warming booth and in thermal-arrest, use water pump dump heat, in heat radiation, use the drawback of water pump as circulation power, utilize the natural law as far as possible, save the energy.
The technical solution adopted for the present invention to solve the technical problems is: by the structure to equipment in system, choose, arrange, the means such as connection, valve control, build multiple cycles, economized loop, make full use of water with gravity descending and hot water meet the natural laws such as cold water is up, in thermal-arrest, heat radiation circulation, do not use driven by power as far as possible.To really needing the link of electricity consumption, reduce time, number of times and the number of devices of electricity consumption as far as possible.Reach and can improve temperature at night, again remarkable energy-conservation effect.
For realizing the present invention, provide a kind of booth energy-conservation warming system, mainly comprise regenerative apparatus 1, solar thermal collector 2, soil-heating device 3, heat abstractor 4 etc., it is characterized in that: described regenerative apparatus 1, by being connected with solar thermal collector 2, forms thermal-arrest loop; By with soil-heating device 3, heat abstractor 4, form heat-radiation loop one; By with heat abstractor 4, soil-heating device 3, form heat-radiation loop two.
Described soil-heating device 3, buries in soil, has accumulation of heat valve 5 in the middle of being connected with regenerative apparatus 1, has heat radiation valve 6 in the middle of being connected with heat abstractor 4.
Described heat abstractor 4, buries in underground, has water pump valve 7, water pump 8 in the middle of being connected with regenerative apparatus 1.
Described regenerative apparatus 1, heat abstractor 4 have heat insulation function.
Described regenerative apparatus 1 capacity is larger, equals soil-heating device 3 capacity and heat abstractor 4 capacity sums.
Described regenerative apparatus 1 capacity is larger, and its whole water bodys, at the heat that obtain and accumulate under average sunshine condition local daytime, can meet canopy temperature requirement at night after release.
Described solar thermal collector 2 has independently hydraulic fluid, can the water of regenerative apparatus 1 be continued, be heated efficiently.
In described system, the sequence of capital equipment opsition dependent is arranged as: regenerative apparatus 1, solar thermal collector 2, soil-heating device 3, heat abstractor 4.
Advantage of the present invention is energy-conservation, efficient.System is placed on highest order by regenerative apparatus 1 and makes its amount of stored heat abundance, and capacity is large, can directly utilize gravitional force naturally to flow through soil-heating device 3 by hot water by heat-radiation loop one, without power consumption; Or by heat-radiation loop two, at nightfall, two water of the heat in regenerative apparatus 1 are imported and are placed in underground heat abstractor 4 fast, utilize hot water to meet the up principle of cold water, the hot water in heat abstractor 4 exchanges with the cold water in relative high-order soil-heating device 3, also without power consumption.Because of regenerative apparatus 1 capacity large, can fully receive heating of solar thermal collector 2, add heat insulation effect, without by heat energy dump elsewhere, avoid heat energy to move damage after neutralization is shifted spy large, make regenerative apparatus 1 obtain higher temperature rise, improved the thermal efficiency, also saved the electric power for dump.The unique electricity consumption link of native system is early morning the water of heat abstractor 4 to be pumped into regenerative apparatus 1, but the electricity consumption time is short, few by pump quantity, very power saving.
Accompanying drawing explanation
Fig. 1 is equipment connection schematic diagram (vertical profile front view).
In Fig. 1, equipment code name and device name are: 1 regenerative apparatus; 2 solar thermal collectors; 3 soil-heating devices; 4 heat abstractors; 5 accumulation of heat valves; 6 heat radiation valves; 7 water pump valves; 8 water pumps; 9 soil; 10 booth bodies.
Embodiment
Below in conjunction with accompanying drawing 1, the present invention will be further described.
Connection device is installed: regenerative apparatus 1 is connected with solar thermal collector 2, lays soil-heating device 3 in soil, heat abstractor 4 is embedded in underground, is connected accumulation of heat valve 5, heat radiation valve 6, water pump valve 7, water pump 8, as shown in Figure 1.
In the daytime thermal-arrest circulation: the water circulation heating of solar thermal collector 2 to regenerative apparatus 1, heat preservation for standby use.Now accumulation of heat valve 5, water pump valve 7 are closed.
Heat radiation circulation at night: the valve of accumulation of heat at nightfall 5, heat radiation valve 6 are opened, and the water of regenerative apparatus 1, under the effect of gravity, enters heat abstractor 4 through soil-heating device 3 automatically.Regulate accumulation of heat valve 5 flows to be advisable for just discharging in one night regenerative apparatus 1 water, also can be set to vary with temperature and flow automatic regulation.
Original state is reset: in early morning, accumulation of heat valve 5 is closed, water pump valve 7 is opened, and starts water on water pump, and after upper water, water pump valve 7 is closed, and restarts new circulation.In 24 hour working time, only has this link electricity consumption.
Embodiment 2: in closed circuit two, utilize hot water to be lighter than the cold water circulation of dispelling the heat.
Connection device is installed: identical with ［ 0019 ］.
In the daytime thermal-arrest circulation: identical with ［ 0020 ］.
Heat radiation circulation at night: water pump valve 7 is opened at nightfall, regenerative apparatus 1 hot water is imported to heat abstractor 4 fast, heat radiation valve 6 is opened, because hot water is lighter than cold water, the hot water of heat abstractor 4 can enter soil-heating device 3 automatically, cold water Ze Youyuan road is descending, so constantly repeats, and automatically completes heat radiation circulation.Regulate heat radiation valve 6 flows to make the heat of heat abstractor 4 distribute and be advisable in one night, also can be set to vary with temperature and flow automatic regulation.
