Description

HEATING AND COOLING SYSTEM OF EQUIPMENT HOUSE}

The present invention relates to a heating and cooling device of a facility house, and more particularly, to automatically maintain cooling and heating while maintaining the indoor temperature and humidity of the facility house most optimal for growing crops, and automatically maintaining the required fuel. The present invention relates to an air conditioning and heating system in an installation house, which can supply and dehumidify while heating and cooling.

In recent years, as the crops are cultivated regardless of the season, the use of facility houses in farms is increasing. These facility houses must maintain a constant room temperature required for the cultivation so that the cultivation will grow normally.

Therefore, in order to maintain the indoor temperature of the facility house, the heater is installed in the winter season to increase the indoor temperature above the outdoor temperature, and in the summer, the air conditioner is installed to lower the temperature below the outdoor temperature.

Since the heater and the air conditioner are operated by the user as needed and the user directly supplies the necessary fuel, the air conditioner and the air conditioner may be operated more than necessary, thereby increasing the consumption of fuel.

In addition, the cultivated material absorbs the necessary nutrients from the roots while performing transpiration through leaves, etc., so that the transpiration needs to be smoothly performed, which is achieved by maintaining the indoor humidity of the facility house below a certain size.

However, conventionally, since the cooling and heating of the facility house is made by simply installing a cooler or a heater in the room, the facility house cannot maintain the optimal state required for growing the crop.

That is, since the cold air or warm air flowing out from the air conditioner or the heater is not evenly transmitted to the indoors and the surface of the facility house, the indoor temperature and humidity are not optimally controlled, and thus, the growth of the crops is slowed.

In addition, each of the above-mentioned cooling and heating units are installed, and the user supplies the fuel necessary for this, and the user operates the cooling and heating unit manually by roughly judging the state of the facility house, and thus requires the labor of workers. There was also a problem that the consumption of the increased by that much.

Accordingly, the present invention has been made to solve the above problems, the object of the present invention is to automatically maintain the room temperature and humidity of the facility house while the cooling or heating is performed to the most optimal state for the growth of crops, It is to provide a heating and cooling device of a facility house that can supply fuel automatically and dehumidify while cooling and heating.

In order to achieve the above object, the present invention is operated when the interior of the facility house is below a certain temperature, the indoor and arable land of the facility house using the hot water heated to a temperature higher than the required temperature to the growth of the cultivated land. Heating means for heating to maintain an optimum state; It is provided with this heating means and operates when the interior of the facility house is above a certain temperature, and uses the cold heat of cold water (ground water) below a certain temperature supplied from the outside for the growth of crops. It consists of cooling means for cooling so that it may be maintained in an optimal state.
