Abstract
The utility model relates to the technical field of a greenhouse, in particular to a winter-warm solar greenhouse using wall ground source heat for temperature regulating. The greenhouse is widely used in many areas in China, however, the temperature is lower in winter in cold areas and the temperature difference between day and night is large, in order to prevent the crops from being frozen and damaged, the temperature in the greenhouse is raised by using the heat source such as stove in winter, therefore the energy is wasted and the planting cost is increased. The utility model adopts the technical scheme that the winter-warm solar greenhouse comprises a back wall, side walls, a support frame and a lighting surface, also comprises a heat exchanger, a circulating pipeline and a blower; through the heat exchanger arranged in the soil layer in the back wall and the side walls of the winter-warm solar greenhouse, the air with lower temperature in a planting chamber performs temperature exchange with the soil so as to raise the temperature, the too low temperature in the planting chamber is prevented, and the normal growth of the crops is ensured. In the utility model, the winter-warm solar greenhouse uses the soil temperature to raise the temperature in the solar greenhouse, and has the advantages of simple structure and easy operation.
Description
Technical field
The utility model relates to the green house technical field, specifically a kind of warm greenhouse by solar heat of winter that utilizes the temperature adjustment of body of wall ground source heat.
Background technology
Green house has obtained in the many areas of China using widely for plantation crops, flowers, vegetables provide temperature condition, and green house has good printing opacity and insulation effect.But it is lower at regional winter temperatures such as northern China, especially day and night temperature is bigger, and daytime is because the sufficient temperature of illumination is higher, to night temperature drop to below the zero centigrade rapidly, although night is at the surface coverage thermal insulation quilt of green house, crops have frostbite still the time in the canopy.For antifreeze cold-resistant, guarantee not frost bitten of the interior crops of canopy, need to adopt the temperature in the thermals source raising booths such as stove fire or electric calorifie installation, wasted the fuel equal energy source, polluted environment, taken manually, increased planting cost.
Summary of the invention
The purpose of this utility model provides a kind of warm greenhouse by solar heat of winter that utilizes the temperature adjustment of body of wall ground source heat.Because the temperature that the following soil temperature of local frost line is gone up above Ground, soil has certain heat storage capacity, and the soil temperature fluctuation is less, does not change with outside air temperature substantially.Effectively utilize winter the underground temperature to improve the interior temperature of green house, guarantee the long-term normal growth of crops, simple to operate.
The technical solution of the utility model comprises warm greenhouse by solar heat of the winter of being made up of back wall, side wall, bracing frame, daylighting face, digs to local frost line under its plantation room floor; Also form by heat exchanger, circulating line, fan blower; Behind warm greenhouse by solar heat of winter, stack soil outside the wall, make soil layer vertically reach horizontal breadth greater than ground to local frost line distance; Middle and lower part behind warm greenhouse by solar heat of winter in wall soil layer or the side walls is provided with heat exchanger, and the heat exchanger two ends are connected with circulating line, and it is indoor that circulating line enters plantation, and fan blower is installed; Or the indoor radiator of circulating line and plantation is connected, and water circulating pump is installed.
The utility model has the advantages that: solved the problem that cold district utilizes crop warming insulations such as booth off-season cultivation vegetables.When sunshine on daytime was sufficient, it was higher to plant indoor temperature, can be the wall and the abundant accumulation of heat of soil in greenhouse effectively; Night, indoor air temperature descended, and opened fan blower, and the lower gas of plantation indoor temperature is sent in the heat exchanger in the wall coating, carried out temperature exchange with soil and improved temperature, flowed back to the plantation chamber again, guaranteed the suitable crop growth of the indoor temperature of plantation; Can utilize soil temperature to be lower than the characteristics of ambient air temperature summer when the indoor temperature of plantation is too high, uses this EGR to be the plantation room temperature lowering.
The utility model is simple in structure, easy to use, rationally utilizes soil temperature, and energy savings has been saved artificial.
Description of drawings
Fig. 1 is the utility model embodiment 1 structural representation
Embodiment
1 heat exchanger among the figure, 2 circulating lines, 3 fan blowers, warm greenhouse by solar heat of 4 winters, 5 kinds are planted chamber, domatic, 7 collecting ditchs of 6 daylighting ditch soil.
Embodiment 1
As can be seen from Figure 1, the utility model comprises warm greenhouse by solar heat 4 of the winter of being made up of back wall, side wall, bracing frame, daylighting face, and its plantation chamber 5 subsurfaces dig to local frost line; Also form by heat exchanger 1, circulating line 2, fan blower 3; Outside warm greenhouse by solar heat 4 back walls of winter, stack soil, make soil layer vertically reach horizontal breadth greater than ground to local frost line distance; The middle and lower part of soil layer is provided with heat exchanger 1 in warm greenhouse by solar heat 4 back walls of winter, heat exchanger 1 apart from warm greenhouse by solar heat 4 of winter after metope 0.2 within the walls---1 meter, heat exchanger 1 two ends are connected with circulating line 2, and circulating line 2 stretches out metope and enters plantation chamber 5, and fan blower 3 is installed.Winter, there was a daylighting ditch warm greenhouse by solar heat 4 front sides, and daylighting ditch soil domatic 6 is horizontal by 30---60 degree angles, strengthen the illumination of plantation chamber 5 edge crops; Collecting ditch 7 is arranged at daylighting ditch bottom, and collecting ditch 7 links to each other with non-irrigated water cellar.
Sunshine on daytime, temperature in the plantation chamber 5 was higher, makes the wall and the abundant accumulation of heat of soil in greenhouse when sufficient; Plant that temperature descend in the chamber 5 night, at this moment open fan blower 3, the lower gases of temperature in the plantation chamber 5 are sent in the heat exchanger 1 in the wall soil layer, carry out flowing back to plantation chamber 5 after the temperature exchange, improve the temperature in the plantation chamber 5, guarantee crop growth with soil.
Embodiment 2
As different from Example 1, in the plantation chamber 5 radiator is installed in the present embodiment, the radiator two ends are connected with circulating line 2, make heat exchanger 1, circulating line 2, radiator form water-flow circuit, and water circulating pump is installed on the closed circuit; Utilize water circulation to improve the temperature of plantation chamber 5.
The installation site of heat exchanger 1 can be chosen in the degree of depth in the soil layer according to the temperature requirement in the plantation chamber 5.
