Description

Greenhouse heating cover

The present invention is used in a greenhouse for various crop cultivation, and in particular, to improve the heating efficiency inside the constructed greenhouse by allowing hot air to be circulated to be heated, and to maintain the indoor temperature and environment as an optimal state. It relates to a greenhouse heating cover to let.

In general, the transparent vinyl used for greenhouse installation is recognized as useful for cultivating various crops by the expected thermal effect by actively blocking outside air and transmitting natural light to warm the air in the greenhouse.

However, in view of the fact that most of these transparent vinyls are used in greenhouse installations because they are unified, the thermal insulation performance to block outside air is weak, and the greenhouses constructed due to their poor shape-keeping capability are poor. It is pointed out that it has a defect that cannot be faithfully exercised.

That is, firstly, the transparent vinyl is formed as a thin film, so the heat insulating performance is poor, and at night time, the efficiency of the heating apparatus operated to maintain the proper temperature in the greenhouse is reduced. In particular, the entire greenhouse is directly heated as a heating apparatus. As a result, as the actual heating area is enlarged, there is a problem in that unnecessary energy consumption is increased, resulting in economical heating.

Second, because the shape holding ability of the transparent vinyl itself is weak, the shape deformation such as sagging or sagging occurs due to wind or snow load, so the installation pipes are installed at close intervals during the construction of greenhouses. There was a problem that the personnel were increased.

Third, the health of workers working indoors contaminated by the exhaust gas emitted from the heating equipment installed inside the greenhouse is detrimental. In severe cases, the heating equipment is overheated and there is a risk of fire. There were problems such as poor conditions.

Complementing the defects of the transparent vinyl as described above, the domestic Utility Model Publication No. 96-4035 by fusing the inner and outer vinyl to the left and right sides of the blocking vinyl so as to cross each other at regular intervals. Insulation applications have been disclosed for the vinyl house thermal insulation vinyl to form a space between the fusion.

The thermal insulation vinyl is a fact that the air present in the space portion acts as a heat insulating layer, it has the advantage that it can block to some extent the heat inside the greenhouse to the outside.

However, the above-mentioned simple thermal insulation effect of the thermal insulation vinyl alone prevents the heat inside the greenhouse from being heat-exchanged to the outside at night and is released to the outside. In particular, by installing a heating device inside the greenhouse, the energy consumption is increased due to the increase of the heating area by directly heating the entire indoor space, and it cannot fundamentally solve the problem of poor environment of the greenhouse for crop cultivation. It was.

Therefore, the present invention is configured so that the hot air supplied from the outside is circulated through the circulation passages formed in two layers of transparent vinyl to be heat-exchanged, firstly, by indirectly heating by the hot air circulating inside the greenhouse to insulate and keep warm It is to realize economical heating through improvement.

Second, it is to enhance the reliability of greenhouse construction by giving shape maintenance ability to cope with adverse effects such as external weather and climate.

Third, to provide a greenhouse heating cover that considers to maintain the temperature and environment inside the greenhouse in an optimal state to promote the convenience of the user.
