The first growth state cooling mode indicates a case in which the height of the growth point of the crop is less than the first threshold value, and the second growth state cooling mode indicates a case where the height of the growth point of the crop is greater than or equal to the first threshold value.

5A and 5B are views showing the operation of the cooling mode in the first growth state according to an embodiment of the present application.

Referring to FIGS. 5A and 5B , the first growth state cooling mode is a case in which the height of the growth point of a crop is less than the first threshold value, and mainly refers to the initial growth period from the planting period to the flowering period.

The first growth state cooling mode is a mode capable of intensive cooling when the height of the growth point is less than the first threshold value.

In addition, when the growth point of the plant is less than the first threshold through the first growth state cooling mode, the colony area is intensively cooled rather than the space cooling that cools the entire space. can be prevented from becoming

When the surface temperature of the fan coil unit 121 is lower than the dew point temperature of the surrounding air, surface condensation occurs and the condensed water falls. The condensed water that has fallen is collected in the water collecting tank at the bottom and supplied to the water supply tank 103 through the pump. It is possible to recover moisture in the air while operating in the cooling mode in the first growth state, and to solve the problem of excessive water use, which was a problem of the fan and pad greenhouse 100 through the recovery of moisture in the air.

6A and 6B are views showing the operation of the cooling mode in the second growth state according to an embodiment of the present application.

Referring to FIGS. 6A and 6B , the second growth state cooling mode is a case in which the height of the growth point of a crop is equal to or greater than the first threshold value, and mainly refers to the middle and late stages of growth, from fruiting to harvesting. In the middle and late stages of growth, the crop is grown to some extent, and adaptability to the environment of the greenhouse 100 occurs, so the fan coil unit 121 and the cooling air duct 122 are separated to convert the space cooling. In the second growing state cooling mode, water is supplied to the water supply tank 103 as in the first growing state cooling mode.

The temperature-sensitive organ of plant horticultural crops is the growth point where cell division occurs, usually the growth point at the tip of the stem or the root. Therefore, in order to prevent high-temperature disturbances caused by exposure to high temperature at the growth point of the stem end, which is the uppermost part of the crop, due to strong solar radiation in the desert area, cooling is performed based on the upper part of the crop through the second growth state cooling mode.

The fan coil unit 121 and the cold air duct 122 are separated, and the fan coil unit 121 is located at the height of the growing point of the crop to blow cold air. In order to grasp the height of the growing point of the crop, the recognition device 135 is attached to the crop, or a camera is attached in the greenhouse 100 to photograph the inside of the greenhouse 100 . An image captured by the camera may be provided to the user.

As the external temperature rises, the temperature rise in the fan direction from the inside of the fan and pad installation greenhouse 100 may increase, and partial temperature and relative humidity unevenness may occur inside the greenhouse 100 depending on the conditions of the greenhouse 100 . can Therefore, after attaching a plurality of temperature and humidity sensors to the inside of the greenhouse 100 to collect the measured values of the temperature and humidity sensors 138 from the controller 133 , the degree of temperature and humidity non-uniformity in the greenhouse 100 is determined. The temperature and humidity sensor 138 may be attached to the growth point of the plant.

By inputting a threshold value to the controller 133 to determine the temperature and humidity non-uniformity, when the temperature/humidity non-uniformity in the greenhouse 100 occurs, the controller 133 operates the electric motor 137 attached to the fan coil unit 121 moving device. control The electric motor 137 moves the fan coil unit 121 to a predetermined position along the rail 136 to perform cooling and dehumidification. At this time, the position of the fan coil unit 121 may be controlled to move to the position of the sensor installed on the rail 136 .

7 is a flowchart illustrating a step-by-step operation method of the desert climate application type greenhouse cooling system 10 according to an embodiment of the present application.

Referring to FIG. 7 , the cold water generating unit 110 generates cooling water for cooling in step S21 .

For example, the cold water generator 110 generates bottled water for cooling, and includes a cooling storage tank 111 and a heat pump 112 . In the heat pump 112 , external air heat may be transferred to a heat exchanger corresponding to an evaporator, or a heat source may be transferred to a condenser in a state in which the compressor is excluded. In the heat pump 112 , the generated or supplied cooling heat is transferred to and stored in the cooling storage tank 111 , and the cooling heat source in the cooling storage tank 111 is transmitted to the supply device of the greenhouse 100 .

In step S22, the cooling unit 120 converts the bottled water into cold air.

For example, the cooling unit 120 includes a plurality of fan coil units 121 and a plurality of cooling air ducts 122 . The fan coil unit 121 blows the cold air into the greenhouse 100 by making cold air with the cold water of the cooling storage tank 111 .

The cold air duct 122 may be connected to the fan coil unit 121 and is disposed under the cultivation bed in connection with the fan coil unit 121 . The cold air duct 122 blows cold air to the crop area where the crop is located.

In step S23 , the cooling unit 120 recovers moisture in the air and supplies it to the water supply tank 103 .

For example, the cooling unit 120 recovers moisture in the air due to condensation on the surface of the heat exchanger and supplies it to the water supply tank 103 . The location and whether to use the fan coil unit 121 are determined according to the mode based on the growth point of crops and the environmental unevenness in the greenhouse 100 .

In step S24, the control unit 130 determines the mode.

For example, the air conditioner 120 is controlled based on at least one of a growth state of a crop and environmental information in the greenhouse 100 . It is determined to operate in the first growth state cooling mode when the height of the growth point of the crop is less than the first threshold value, and in the second growth state cooling mode when the height of the growth point of the crop is greater than or equal to the first threshold value.

In step S25, the control unit 130 controls the cooling unit 120 according to the determined mode.

For example, in the first growth state cooling mode, when the growth point of a plant is less than the first threshold value, a local air conditioning method capable of intensively cooling a community area is more efficient than space cooling that cools the entire space. The second growth state cooling mode is a case where the first threshold value or more, and the fan coil unit 121 is controlled to be the same as the height of the growth point of the crop to cool the entire greenhouse 100 .
