Detailed description of the invention:

Fig. 1 is perspective view of the present invention;

Fig. 2 is side view of the present invention;

Fig. 3 is heating system connection figure of the present invention.

Specific embodiment:

Referring to each figure, a kind of transparent enclosure structural phase transition energy storage heating system for greenhouse brooder, including greenhouse ontology, greenhouse Body exterior installs air type slot light collection solar thermal collector 2, and greenhouse ontology one side wall is equipped with indoor air inlet 3, greenhouse Bodies top is equipped with indoor air outlet 9, and ontology another side wall in greenhouse is transparent glass enclosure wall, the glass of transparent glass enclosure wall It is packaged with phase-change material paraffin 5 in interlayer, is laid with accumulation of heat coil pipe 1, accumulation of heat coil pipe 1 among the glass sandwich of transparent glass enclosure wall Both ends are connect with air diverter 11 and air junction station 12 respectively, and air diverter 11 is poly- by pipeline one and air type slot type The connection of 2 one end of light solar thermal collector, pipeline one are connect by air outlet pipeline with indoor air outlet 9, are installed and are adjusted on air outlet pipeline Air-valve D7-4 is saved, air junction station 12 is connect by coil circuit with indoor air inlet 3, and air inlet 3 passes through air inlet pipeline and pipe The connection of 2 other end of Lu Eryu air type slot light collection solar thermal collector, 2 both ends of air type slot light collection solar thermal collector point Other mounting temperature sensor A6-1 and temperature sensor B6-2 installs frequency conversion fan 4, the air inlet on the air inlet pipeline Installation and adjustment air-valve B7-2, adjusting air valve A7-1 and adjusting air valve C7-3 are distinguished in pipeline, pipeline two and coil circuit;Described Installation interior sensor 10 and controller 8 in greenhouse ontology, controller 8 are passed with interior sensor 10, temperature respectively by conducting wire Sensor A6-1, temperature sensor B6-2, adjusting air valve D7-4, adjusting air valve B7-2, adjusting air valve A7-1 and adjusting air valve C7-3 Connection.The transparent glass enclosure wall is oblique.The transparent glass enclosure wall is by transparent toughened glass or organic Glass is made, and forms closed assembly with its internal phase-change material 5 filled and the accumulation of heat coil pipe 1 being laid with.The heat-storage plate Pipe 1 and air diverter 11 and 12 joint of air junction station are that bite type is connect or adhered connection, accumulation of heat coil pipe 1 are adopted It takes four pipes to erect column dragon form of wagging the tail parallel to be laid with or the four parallel row dragons of pipe wag the tail form laying.

When this is used for the transparent enclosure structural phase transition energy storage heating system operation of greenhouse brooder, the air type slot light collection sun Energy heat collector 2 assembles solar energy, heats the Cryogenic air from coil circuit, and the hot-air of heating is then sent into accumulation of heat coil pipe 1.Heat a part of hot-air is spilt into greenhouse ontology by way of thermally conductive and convection current under action of thermal difference and carries out heat supply, another Partial heat, which is absorbed by way of thermally conductive and convection current by phase-change material paraffin 5, to be stored.Cryogenic air after heat dissipation is with interior The interior heating of air-supplied type groove formula light-concentrating solar heat-collection device 2 together of the benefit wind of air inlet 3.It recycles repeatedly, by solar energy It is converted into heat to store to greenhouse ontology heat supply and by phase transformation material paraffin 5, guarantees the stable thermal environment in greenhouse.

Currently, phase-change material is a kind of new function material, it can store or discharge a large amount of in transformational substance state procedure Thermal energy has the characteristics that phase transition temperature is adjustable, unit volume energy storage density is big, and compared with normal physical property energy storage building material, phase transformation stores Energy construction material has biggish heat storage capacity within the scope of room temperature, imitates to Building Indoor Environment with good heat-accumulation temperature-adjustment Fruit, being applied to architectural exterior-protecting construction can the effectively save energy.Phase-change material paraffin 5 in this system receives solar energy on daytime Meanwhile the heat of air in accumulation of heat coil pipe 1 is absorbed, it is mainly effectively stored in the form of latent heat, sensible heat form effectively stores for part. At night, environment temperature is slowly reduced, when room temperature gradually close to the freezing point of phase-change material paraffin 5 when, phase-change material paraffin 5 by It gradually solidifies, the heat of storage is gradually released in greenhouse brooder in phase transition process, to greenhouse heat supply, guarantees the growth of crop Demand.

Winter in spring, on sunny daytime, the work of active phase-changing energy-storing system.When night or rainy days or bad weather When, first from active phase-changing energy-storing system to indoor heating, to meet plant growth demand;When warm room temperature is unsatisfactory for crop Growth demand when the heating load deficiency of active phase-changing energy-storing system, opens passive heating system and carries out heat supply.Wherein passive heat supply System, that is, human assistance heating, is determined by field condition.

Utilize the temperature sensor A6-1 and temperature sensor B6-2 at 2 whole story end of air type slot light collection solar thermal collector Temperature difference control air type slot light collection solar thermal collector 2 start and stop, the temperature difference sets according to on-site actual situations.Chamber sense The main function of device 10 is monitoring inside greenhouse thermal environment, when greenhouse temperature is lower than the growth demand of crop or in opening chamber Adjusting air valve D7-4 is by the quick heat supply of indoor air outlet 9, or opens passive heating system, in 7 basic control system of adjusting air valve The flow direction of hot and cold air and equipment start-stop.Adjusting air valve C7-3 is normally closed, adjusting air valve A7-1 and adjusting air valve B7-2 It usually opens, adjusting air valve D7-4 is only just opened when air outlet 9 is opened in greenhouse ontology.

This is used for the transparent enclosure structural phase transition energy storage heating system of greenhouse brooder, is making full use of the renewable sun of cleaning While energy resource, in conjunction with the phase transformation heat charge and discharge of phase-change material, greenhouse brooder can be effectively improved in winter in spring Indoor Temperature Degree can especially be stablized at night and guarantee the growth demand of crop to greenhouse heat supply.The heat supply of the invention both effectively save brooder Energy consumption, and brooder indoor thermal environment can be stablized under complicated weather conditions, guarantee plant growth, increases yield, it is more at one stroke ?.

In conclusion this is used for the transparent enclosure structural phase transition energy storage heating system of greenhouse brooder, using filling phase transformation material Work stone wax 5, effectively save greenhouse is for thermal energy consumption;Using the phase transformation heat charge and discharge of phase-change material paraffin 5, improve the hot ring in greenhouse Border guarantees that crop obtains stable growing environment on daytime and night, establishes one to adapt to complicated climate change for greenhouse Fixed basis, compensates for the deficiency of traditional greenhouse, and meets market development demand, great future market development prospect.
