Specific embodiment

As shown in Figure 1, 2, 3, the energy efficiency temperature regulating device of the greenhouse gardening of the utility model, including storage heat releasing unit 1, Ventilation duct 2 and trapdoor 3；It is equidistantly arranged in parallel along the direction of greenhouse length to store heat releasing unit 1, adjacent two store heat releasing unit Distance be 5-20 meter, storage heat releasing unit include being embedded in the snakelike floor heating pipe 11 of greenhouse underground and on greenhouse ground Heat exchanger 12, heat exchanger include gilled radiator 121 and the circulating fan 122 positioned at radiator side, floor heating pipe Water inlet end 111 extends upward ground and connect with the water outlet of radiator 123, water outlet 112 extends upward ground and leads to Piping pump 13, water heater 14 are connect with the water inlet 124 of radiator, and radiator, pipeline pump, water heater and floor heating pipe form one A circulation loop is additionally provided with the expansion for adjusting conduit volume on the pipeline between the water inlet and water heater of radiator Bag or expansion drum 15；Ventilation duct 2 is corresponding with the quantity of heat releasing unit is stored, and is embedded in the underground for storing heat releasing unit side, ventilation Pipe is the U-tube that both ends protrude from ground, and air outlet 21 is located in greenhouse, and air inlet 22 is located at outside greenhouse and outward bending shape At horizontal air inlet；The planting greenhouse of the utility model includes heat absorption wall 4 and film ceiling 5, and trapdoor 3 is to be fixed on greenhouse Heat absorption wall top surface and two parallel vertical skylights being fixed on greenhouse film skeleton 6 are fixed with water among each vertical skylight Flat turn axis 31, horizontal rotating shaft is connected to motor by linkage mechanism, and the angle rotated by motor control skylight；Pipeline pump is followed Ring fan, water heater and motor are connect with the temperature sensor being arranged in greenhouse respectively, and sensor includes greenhouse temperature sensor With plastic shed soil temperature sensor.

The working principle of the energy efficiency temperature regulating device of the greenhouse gardening of the utility model, due to heat exchanger, pipeline pump, Water heater and floor heating pipe are concatenated into a circulation loop, when sunlight on daytime irradiates sufficient, start to warm up in greenhouse, temperature passes When sensor detects that the room temperature of greenhouse is more than 2 DEG C higher than the temperature of soil, the circulating fan of pipeline pump and heat exchanger is opened automatically It opens, the heat in greenhouse is continually passed to floor heating pipe, and the temperature of soil is made to be rapidly reached the temperature of plant root growth；When When temperature sensor detects that the temperature of soil reaches the optimum temperature upper limit of plant root growth, pipeline pump and circulating fan are certainly Dynamic to close, trapdoor is opened, and since the hot-air in greenhouse is toward rising, greenhouse lower part is made to form negative pressure state, and air is from position Enter ventilation duct in the ventilation duct air inlet outside greenhouse, then enter greenhouse from air outlet and supplemented, endlessly supplement is empty Hot-air is discharged constantly from trapdoor in gas, in this way, the air of inside and outside convection current can rapidly lower the temperature of greenhouse, Floor heating pipe also no longer heated heating, allows plant to grow in optimal growth temperature range, as shown in Figure 4；And when The night screen has hung down, Start to cool down in greenhouse, temperature sensor detect greenhouse room temperature and soil temperature gap less than 2 DEG C when, pipeline pump and follow Ring fan is automatically closed, and due to the presence of hot water in floor heating pipe, and soil has preferable warmth retention property, the soil moisture at this time It is still adapted to the temperature of plant root growth；When the temperature of soil is lower than plant root growth optimum temperature lower limit, water heater, Pipeline pump, circulating fan automatically turn on, and make in soil and canopy while heating up；When to be slightly above plant root growth best for the soil moisture When lowest temperature, water heater is closed, and the hot water in floor heating pipe is allowed to recycle in soil and canopy.

Above only energy efficiency temperature regulating device one embodiment of the utility model greenhouse gardening illustrates, but should Embodiment not to limit the protection scope of the utility model, all equivalence enforcements without departing from technical solutions of the utility model or Change, such as the change of floor heating pipe, heat exchanger and trapdoor structure, should be included in the scope of the utility model.
