Description

{Greenhouse with ventilation system}

The present invention relates to a vinyl house used as a crop cultivation or a work site, and more particularly, to a vinyl house used for cultivating a crop or a work site, and more particularly, It is about a plastic house that uses the geothermal heat to ensure stable cooling and freezing cold or warmth in the plastic house depending on the season.

Generally, a vinyl house is constructed by arranging a round metal frame in a tunnel structure and fixing it on a ground, and a transparent plastic is covered on the top of the steel frame. Various greenhouse cultivation is possible in the winter due to the greenhouse effect, And it is possible to cultivate crops with high productivity and productivity throughout summer, autumn and winter seasons, and is widely used for cultivation of various crops.

In such a vinyl house, the temperature and humidity of the inside must be kept constant so that the crop can grow properly. It is very important to control the temperature and the humidity, and as shown in Registration Practical Utility Model No. 20-0440859, A vinyl house capable of controlling the ventilation and the temperature by forming the opening for assisting ventilation and forming a fountain hose for controlling the temperature and humidity of the plastic house by spraying cold water or hot water on the side of the opening has been registered and registered.

In addition, in the case of Patent No. 10-1074757, in a facility house, a device for performing hot and cold air heat exchange using a blowing fan, the device comprising: a duct part having a plurality of conduits installed between a room and a ground of the facility house; An indoor heat exchanger installed in the indoor space of the facility house for performing heat exchange with the blowing air, an electric heating duct installed in the indoor space of the facility house for discharging the blowing air after heat exchange, and auxiliary means provided on the duct portion for causing latent heat of vaporization of water There is an underground cold / hot air heat exchanger for facility house registered.

Also, as disclosed in Japanese Laid-Open Patent Publication No. 10-2016-0135015, a base plate is provided so as to be disposed so as to be opposed to each other along the extending direction of the roof frame, a base plate formed of a material having elasticity, According to the vinyl cover fixing bar of the vinyl house having the elastic layer in close contact and the vinyl house construction method using the cover bar, it is possible to fix the vinyl integrally with the roof frame in the pressed state of the vinyl from the outside of the vinyl, And thus it is possible to suppress the tearing of the vinyl.

However, in the case of a vinyl house in which the temperature and the humidity are controlled using ventilation and cold water or hot water in the vinyl house, the temperature of the vinyl film in the vinyl house is controlled not by directly being related to the internal temperature of the vinyl house, The internal temperature and the humidity are controlled. Therefore, it takes considerable time and a great deal of time for the internal temperature of the vinylhouse to be varied. Therefore, the inefficiency is very low and the economic expenditure is also considerable, which is extremely uneconomical .

Also, in the case of a vinyl house in which temperature control using geothermal heat is performed, since the air inside the plastic house is circulated as it is, the temperature control function is very weak, and the circulation structure is very complicated and many devices must be used There is a problem that the burden of the facility cost is greatly increased.

In the case of the vinyl house having the vinyl fixing structure using the cover bar, the cost of the vinyl fixing structure using the cover bar is excessively excessive in the total installation cost of the vinyl house, which increases the installation cost of the entire vinyl house excessively Of course, when the vinyl film flows due to wind blowing or impact, the interference part of the lid bar breaks down, so that the service life of the house is remarkably deteriorated and the damage of the crop is extremely severe.

Accordingly, there is an urgent need to develop a vinyl house that can maintain a constant internal temperature regardless of the season through effective insulation and effective temperature maintenance while suppressing an excessive rise in facility cost.
