Embodiment 1

[0048] Such as Figure 1-3 The shown low-energy double-membrane pressurized greenhouse includes a greenhouse body 10 composed of an inner membrane 1 and an outer membrane 2, an air supply part 14 arranged at one end of the greenhouse body 10, and an air supply part 14 arranged at the other end of the greenhouse body 10. The entrance and exit 11, the inner membrane 1 and the outer membrane 2 divide the interior of the greenhouse into an inner building 10a and an outer building 10b, and the air supply part 14 supplies the outside air into the inner building 10a, so that the air pressure in the inner building 10a is greater than that of the outside air pressure;

[0049] Both the inner membrane 1 and the outer membrane 2 are made of environmentally friendly and degradable polymer materials, and the service life can reach about 8 years. The anti-drip and defogging effects are synchronized with the life of the membrane. The compressed air belt acts as a heat transfer buffer, repla...

Embodiment 2

[0062] Such as Figure 4 As shown, this embodiment is the same as Embodiment 1, except that: when water needs to be poured into the greenhouse, a water supply unit 60 is also provided at the air inlet of the air supply unit 14 . The function of the water supply part 60 is to reduce or increase the temperature of the air at the air inlet of the air supply part 14 .

[0063] The water supply part 60 includes a frame body 20, the frame body 20 surrounds the air inlet of the air supply part 14, a filter 30 arranged in the side wall of the frame body 20, and a water supply line 70 arranged on the frame body 20; The filter 30 is full of holes, and the holes of the filter 30 are formed in a direction crossing each other on a plane, and the filter 30 can absorb water dropped from the water supply line 70 and remove foreign matter in the external air; The lower part of the main body 20 is provided with a drain line 21 capable of recovering water dropped from the water supply line 70 ....

Embodiment 3

[0067] Such as Figure 17 As shown, this embodiment is the same as Embodiment 1, the difference is that, in addition to the inner membrane 1 and the outer membrane 2, the greenhouse is also provided with a middle membrane 9 between the inner membrane 1 and the outer membrane 2, and the middle membrane 9. Separate the outer building 10b into an outer building 10c and an outer second building 10d. Check valves 4 are provided on the top and bottom sides of the inner membrane 1 and the middle membrane 9, and the outer membrane 2 is provided with an exhaust valve. window3.

[0068] After adding one layer of middle film 9, one more layer of high-pressure air belt can be added as a heat transfer buffer zone, which can further effectively reduce heat loss.

Abstract

The invention relates to the technical field of pressurized greenhouses, in particular to a low-energy-consumption double-film pressurized greenhouse. The low-energy-consumption double-film pressurized greenhouse comprises a greenhouse body composed of an inner film and an outer film and an air supply part arranged at one end of the greenhouse body, the inner film and the outer film divide the interior of the greenhouse into an inner building and an outer building, the air supply part supplies external air into the inner building, and the air pressure in the inner building is larger than the external air pressure; and an exhaust window is arranged at the top of the outer film, exhaust mechanisms are arranged at the top and the bottom of the inner film, and the air flow direction of the exhaust mechanisms is from the inner building to the outer building. The low-energy-consumption double-film pressurized greenhouse can obviously improve the crop growth environment and the livestock growth environment, enhance the heat preservation effect in the greenhouse, effectively reduce crop diseases and insect pests, and obviously improve the quality and yield of crops and livestock.

Description

technical field [0001] The invention relates to the technical field of pressurized greenhouses, in particular to a double-membrane pressurized greenhouse with low energy consumption. Background technique [0002] The greenhouse can produce crops all year round because it can promote cultivation and inhibit cultivation, and can also plant special crops that cannot be cultivated in the open field, thereby greatly increasing the income in a certain area. Greenhouses are widely used in mating and breeding because they can freely adjust the growth stages of many crops, adjust temperature, humidity, and light to study the response of crops, and can study the relationship between environment and crop growth. [0003] When choosing a place to build a greenhouse, you should consider the possibility of utilizing sunlight, the height of the groundwater table, water quality, ventilation, and various work conveniences. Greenhouses are generally built in east-west or north-south rectangl...
