Description

A kind of greenhouse collection regenerative apparatus
Technical field
The utility model belongs to greenhouse solar and efficiently utilizes field, is related to a kind of greenhouse collection regenerative apparatus.
Background technology
To ensure the normal production of crop, cold snap need to aid in greenhouse when wide geographic area carries out agricultural production Heating, at present coal-fired heating system (CFHs, coal fired heating system) and natural gas heating system (GFHs, Gas fired heating system) be various countries greenhouse main heating system.Since space is big in chamber facility, heat insulating ability The reason such as poor causes greenhouse heating huge energy consumption.For greenhouse winter nighttime temperature it is relatively low the problem of, for many years, numerous domestic Scholar improves storage, emission capacity has carried out numerous studies around how to improve utilization of the greenhouse to solar energy.In general, greatly Part research is the thinking from enhancing soil or wall heat storage capacity.But this passive storage, exotherm, its storage are put Than relatively limited, Low Night Temperature especially time after midnight Low Temperature Problems are solved still without thorough for the lifting of thermal energy power.In recent years, by daytime The solar energy of excess enthalpy stores the new direction as Greenhouse System research, such as the ground used in vinyl house in a variety of ways What is used in middle heat-exchange system, greenhouse can be stored in heat the polyene alkane resin material solar energy collection of water tank and thin solum Solar water heating system of external used in hot device, small-sized greenhouse etc., these systems can be when nocturnal temperature be relatively low Actively release energy into greenhouse, be increasingly becoming greenhouse area research hot spot.
For current research, Chinese patent CN106105905A discloses a kind of curved surface Nie Er lens light gatherings and facility agriculture The solar thermal collection system that industry combines.The system is combined using integral slip type concentrator with industrialized agriculture greenhouse, and energy will too Sunlight high aggregation, realizes that solar energy and agricultural planting technique supply mutually utilization., can not large area but the system is excessively complicated Promote.Chinese patent CN104838924A discloses a kind of greenhouse solar air heat collection heat accumulation circulatory system.The system Ground one layer of the lower berth heat insulating board in greenhouse, surrounding are turned up to ground, overall groove profile are formed, then in heat insulating board Upper embedded heat collecting conducting pipe, underground thermal-arrest is sent to by the heat of solar energy air heat collector by wind turbine, Fan pipeline, guide duct Pipe is transmitted to soil horizon thermal-arrest, and to being heated in the canopy of ground, which makes full use of the night solar air heat collection heat accumulation circulatory system Solar energy, reduces thermal loss.
The utility model is mainly for greenhouse in cold season fair weather, and indoor temperature was usually above plant and fitted daytime The temperature preferably grown, and the temperature at night often relatively low phenomenon, on the basis of forefathers study, it is proposed that a kind of greenhouse collection " surface cooler " is creatively changed into heat collector by regenerative apparatus, the device, the heat in the indoor high temperature air of temperature on daytime It is stored into water, realizes transfer of the heat in the time, spatially, improves the utilization rate of solar energy, solve night in winter greenhouse Temperature it is too low influence crop normal growth the problem of.
Utility model content
A kind of greenhouse collection regenerative apparatus, including with lower part:As " surface cooler " 1 of heat collector, air circulation fans 2, Water pump 3, pipeline 4, heat accumulation pond 5 and control device 6;
The heat accumulation pond 5 is located at below the ground level in greenhouse, and water pump 3 connects one end of water supply pipe 4, water supply pipe 4 The other end be connected with the water inlet end of surface cooler 1, water return pipeline 4 is connected with the water outlet of surface cooler 1, and the other end stretches into water storage In pond 5, air circulation fans 2 are installed on the side of surface cooler 1, blow to surface cooler.
The control device 6 is mainly made of air-temperature sensor, cooling-water temperature sensor and controller etc..
The surface cooler 1 is installed on the eminence position of the greenhouse interior space, because the temperature of eminence air is higher, without prejudice to The growth of warm indoor crops and the activity of staff.
The beneficial effects of the utility model are as follows compared with existing collection regenerative apparatus at present:
1. apparatus structure is simple, cost is low, easy for installation, reliable, can be in newly-built or original temperature indoor location.
2. by using the device, while solar energy is stored, inside greenhouse causes relatively wet because of the reduction of temperature Degree is improved, and is more advantageous to the growth of plant.
Brief description of the drawings
A kind of front views of greenhouse collection regenerative apparatus of Fig. 1.
Wherein, 1- surface coolers, 2- air circulation fans, 3- water pumps, 4- pipelines, 5- heat accumulations pond, 6- control devices.
Embodiment
The utility model provide a kind of solar energy highly effective utilize field greenhouse collection regenerative apparatus, below in conjunction with the accompanying drawings and Embodiment is further described specific embodiment of the present utility model.
As shown in Figure 1, a kind of greenhouse collection regenerative apparatus described in the utility model, mainly includes:" surface cooler " 1, air Circulating fan 2, water pump 3, pipeline 4, heat accumulation pond 5 and control device 6.
A heat accumulation pond 5, below ground of the heat accumulation pond 5 in heliogreenhouse are built in the corner of heliogreenhouse.Water pump 3 is placed In pond, by one end of 3 water outlet of water pump connection water supply pipe 4;The other end of water supply pipe 4 and the water inlet end of surface cooler 1 Connection;Water return pipeline 4 is connected with the water outlet of surface cooler 1, and the other end is stretched into cistern 5.Air circulation fans 2 are installed on table The side of cooler 1, blows to surface cooler.
Control device 6 is mainly made of air-temperature sensor, cooling-water temperature sensor and controller etc..
Usually, surface cooler 1 is installed on the eminence position of the heliogreenhouse interior space, high at ridge lower section or adverse grade It is higher to locate the temperature of air, without prejudice to the growth of warm indoor crops and the activity of staff.
The operation method of the greenhouse collection regenerative apparatus is as follows:
(1) daytime, when the sensor in control device detects the difference of water temperature in the indoor temperature of temperature and heat accumulation pond During higher than setting value, water pump and air circulation fans are opened at the same time.On the one hand, work of the indoor high temperature air of temperature in circulating fan Under, the pipeline surface of " surface cooler " is transferred heat to, raises the temperature of " surface cooler " pipeline;On the other hand, in water pump Under effect, the water of low temperature is flowed into " surface cooler " pipeline, and the specific surface area for utilizing " surface cooler " huge transmits rapidly heat Into water.In this way, just by the circulation of water by the thermal energy storage of warm room air redundancy in the water in heat accumulation pond, realize Transfer on the locus of thermal energy.
(2) when the sensor in control device detects that the difference of the indoor temperature of temperature and water temperature is less than setting value, close Closed loop wind turbine and water pump, collection heat-accumulating process stop.
(3) in general, heliogreenhouse needs to be heated under April in November to next year and special weather, therefore, this Device is mainly run in April in November to next year.
