Description

Greenhouse heating & Circulating only for the Air of Tube Layer

The present invention relates to a method for constructing a double-coated greenhouse having a heating and other effects by heating and circulating only the air layer as a greenhouse coated with a double-tube plate (1) covering material having an air layer, and more specifically, two transparent sheets in symmetry. By joining hard plates (plastic, PET, glass, etc.) to form a sealed tube air layer, the greenhouse is covered with a coating material that forms a sealed tube air layer, which is an air septum interlayer, between the inside and outside of the greenhouse to minimize heat loss. Automatically controlled heating circulation and the entire closed air tube layer constitute a single closed circuit to heat and circulate only the tube layer to control heating and melting so that snow does not accumulate and prevent snowfall damage to the greenhouse. A method and apparatus for constructing a double-coated greenhouse with a tube bed air heating circulation for automatically treating condensed water caused by rapid temperature difference in .

Conventional methods use a single vinyl sheet (PE film), PET, glass, and other hard plates to construct a greenhouse. The greenhouse's normal internal temperature (15-20 ℃) and outside air (-5-10-10 ℃) The deviation between and becomes large (△ t = 20 ~ 30 ℃) and the heat loss is increased. On the other hand, in order to keep the proper temperature (15 ~ 20 ℃) as convection heating at the arable land where crops are grown inside the greenhouse. The 5m-high greenhouse ceiling maintains high temperature around 30 ℃, so that high energy is placed in the unneeded area, which maximizes heat loss due to greater outside air and temperature deviation, making it an energy and consumption type heating method.

On the other hand, there is a double greenhouse, but the warming effect is better than that of a single greenhouse, but the air in the interlayer is not sealed and it is communicated with the air inside the greenhouse, causing convection. From the point of view of farmers, it is difficult to guarantee the profit of facility cultivation by oil heating, and new technology is required for oil-consumption-type greenhouses, where supply and demand are unstable and national prices continue to rise. In addition, if the greenhouse temperature outside drops and the snow falls and the weight of snow piles up on the roof of the greenhouse coating, the entire structure of the plastic house (greenhouse) cannot be prevented from falling down. The condensation water in the greenhouse due to the temperature difference between the inside and outside of the greenhouse interferes with crop growth and also requires a lot of manpower for its treatment.

The present invention forms a tube plate (1) having an air layer (30) in the plate by adhering the greenhouse coating material in the upper plate (1-1) and the lower plate (1-2) in a transparent hard plate in order to solve the above problems. And connecting the entire tube plate 1 to a closed air circuit (FIG. 8), and inserting a warming circulation 700 in which heating and circulation are automatically controlled into a closed circuit (FIG. 8), thereby forming an air layer in the tube plate (1). 30) to maintain the required temperature at a constant temperature to minimize the temperature difference between the inside and outside of the greenhouse to minimize the loss of solar energy received during the day, when the outside temperature drops the temperature of the air layer (30) to place the required temperature in the greenhouse It prevents snow damage by raising the temperature of the air layer so that snow does not accumulate when snow damage is expected or when the outside temperature drops sharply, and prevents snow damage, and unlike the conventional greenhouse, does not use the entire air inside as a convection heating method. , Heating only the tube layer air, heating by radiating method from the tube plate (1) to the inside of the greenhouse, heating, and minimizing the loss of the heat of preservation, tube layer air heating circulation double covering material to maintain the temperature required for crop growth It is an object of the present invention to provide a method for constructing a greenhouse.

When the water level exceeds 1000, the water is discharged to the outside through the condensation outlet 820, and the water 850 remaining in the water level 1000 stays between the supply pipe 900 and the outside air. By acting as a barrier to outside air, the entire closed circuit is maintained.

By covering the greenhouse with a tube plate (1) formed by double-bonding a transparent hard plate to have an air layer (30), a diaphragm layer is formed between the inside and the outside, so that the temperature deviation between the inside and the outside of the greenhouse is lowered, thereby reducing the heat loss of the greenhouse to reduce the heating cost. On the other hand, the air layer of all the tube plates 1, which is one of the features of the present invention, is connected in a closed circuit to be isolated from the air in the greenhouse, and the air in the tube plates 1 does not cause self-convection and circulates. The load is very small, so it is easy to warm and equalize the entire air in the closed circuit to the target temperature so that it can sense the temperature in the outside and the greenhouse and keep the whole uniform at the required temperature, and the air layer itself radiates into the greenhouse as a radiant heat source. By radiating heat waves and heating, it becomes possible to provide an energy-saving greenhouse away from the existing energy-consuming convection heating.

In addition, the PE film existing greenhouse, commonly referred to as a vinyl house, is vulnerable to snowfall, but the present invention has many snow damages. It prevents damage to farmers by preventing meltdown and damage to crops by melting it, and prevents farmers from economic loss, and does not require the use of auxiliary coatings or curtains to treat condensation water caused by rapid temperature differences between inside and outside the greenhouse. Improved profitability of facility cultivation by reducing the labor force in rural areas with insufficient hands by automatically discharging condensed water with the siphon pipe (800) system. Existing greenhouses and materials are patented in foreign countries with long history of use. Although there are many import requests for greenhouse materials from China, it is difficult to export them because they are tied to patents. Greenhouse materials, the company's unique technology, can be freely exported, increasing the profitability of facility farmers in Korea and around the world.
