The heating and cooling system for glass greenhouse floor improves the productivity of the products produced in the glasshouse by installing the piping pipes on the bottom of the glasshouse and controlling the temperature inside the glasshouse by controlling the amount of cold water or hot water supplied to the piping pipes And enhance quality competitiveness.

2 is a view for explaining a floor heating / cooling system for a glasshouse in accordance with another embodiment of the present invention.

Referring to FIG. 2, the floor heating / cooling system for glasshouse heating includes a floor layer 200, 210 and 220 including N regions, pipes 201, 211 and 221, temperature sensors 202, 212 and 222, A pump 230, a flow control unit 240, and a control unit 250.

The bottom layer 200, 210, 220 may be disposed at the bottom of the glass greenhouse. The bottom layers 200, 210, and 220 may include a bottom layer 200 of the first region, a bottom layer 210 of the second region, and a bottom layer 220 of the third region. In the present embodiment, the case where the bottom layer is composed of three regions will be described as a reference, but the number of regions is not limited to this and can be variously implemented.

The piping pipes 201, 211, and 221 are installed inside the bottom layers 200, 210, and 220, and cold or hot water can flow into the bottoms. The first piping pipe 201 is installed inside the bottom layer 200 of the first region and the second piping pipe 211 is installed inside the bottom layer 210 of the second region and the third piping pipe 221 May be installed inside the bottom layer 220 of the third region.

The temperature sensors 202, 212, and 222 may measure temperatures around respective regions of the bottom layers 200, 210, and 220, respectively. For example, the first temperature sensing sensor 202 may measure the temperature of the bottom layer 200 of the first region, and the second temperature sensing sensor 212 may measure the temperature of the bottom layer 210 of the second region And the third temperature sensing sensor 222 can measure the temperature of the bottom layer 220 of the third region.

The circulation pump 230 may supply cold water or hot water generated by the cold / hot water generating device to the piping pipes 201, 211, and 221.

The flow rate regulator 240 may be disposed between the circulation pump 230 and the piping pipes 201, 211, and 221. The flow control unit 240 can control the amount of cold water or hot water supplied to the piping pipes 201, 211, and 221.

The control unit 250 controls the flow rate regulator 240 based on the temperatures measured by the temperature sensors 202, 212 and 222 so that the bottom layer 200 of the first region, the bottom layer 210 of the second region, The amount of cold water or hot water supplied to the first piping pipe 201, the second piping pipe 211, and the third piping pipe 221 present in the bottom layer 220 of the three regions is adjusted differently, Can be adjusted constantly. For example, if the set temperature is 20 degrees, the temperature of the bottom layer 200 of the first region is 10 degrees, the temperature of the bottom layer 210 of the second region is 15 degrees, and the temperature of the bottom layer 220 of the third region The control unit 250 increases the amount of hot water supplied to the first piping pipe 201 and the third piping pipe 221 and increases the amount of hot water supplied to the second piping pipe 211 So that the flow rate regulator 240 can be adjusted. Accordingly, by keeping the temperature inside the glasshouse unchanged depending on the position, the temperature of the entire interior of the glasshouse can be kept constant. By doing so, it is possible to solve the problem that the quality and the productivity of a product to be produced are lowered depending on the position inside the glass greenhouse.

3A and 3B are views for explaining a case where the cold / hot water generating apparatus is a heat pump.

Referring to FIGS. 3A and 3B, the cold / hot water generating apparatus may include a heat pump 310. The heat pump 310 may include a compression unit, an evaporation unit, an expansion unit, and a condensation unit.

3A is a view for explaining a case of a cooling mode. The compression section 320 can compress the low-temperature and low-pressure refrigerant gas. The condenser 330 can cool the high-temperature and high-pressure refrigerant gas compressed by the compressing unit 320 and condense it. The expanding part 350 can be decompressed so that the refrigerant liquefied in the condensing part 330 can be easily evaporated. The evaporator 340 can evaporate the decompressed refrigerant. The circulation pump 360 circulates the cooled cold water due to heat exchange with the evaporator 340 and supplies the circulated cold water to the storage tank 300. The four-way valve 370 can change the path through which refrigerant gas travels. The heat pump 310 can repeat this process to generate cold water. When the cold water stored in the storage tank 300 is supplied to the glass greenhouse, the temperature inside the glass greenhouse can be lowered.

FIG. 3B is a view for explaining a case of a heating mode. The expanding portion 351 can be decompressed so that the refrigerant liquefied in the condensing portion 341 can be easily evaporated. The evaporator 331 can evaporate the decompressed refrigerant. The compression section 321 can compress the low-temperature low-pressure refrigerant gas generated by the evaporation section 331. The condensing section 341 can cool and condense the high-temperature and high-pressure refrigerant gas compressed by the compression section 321. The circulation pump 361 exchanges heat with the condenser 341 and circulates heated hot water to the storage tank 301. The four-way valve 371 can change the path through which refrigerant gas travels. The heat pump 311 can generate hot water by repeating this process. When the hot water stored in the storage tank 300 is supplied to the glass greenhouse, the temperature inside the glass greenhouse can be increased.

As described above, by implementing the cold / hot water generating apparatus using the heat pump, it is possible to reduce the facility investment cost and the cooling / heating maintenance cost.
