Description

Technical Field

[0005]

[0001] The present invention belongs to the field of greenhouse thermal environment control technology, and relates to a solar heat pump heating and cooling system that uses the solar radiation energy flowing into the greenhouse and the heat generated by LEDs installed and operated on a vertical bed as heat sources.

Background Art

[0002] After sunrise, the temperature in the greenhouse gradually rises and, even in winter, rises to a temperature far above the appropriate growth temperature condition (below 28°C) during the midday sun (rising to above 40°C in midsummer). Such an increase in the temperature inside the greenhouse not only hinders the growth of crops but also causes significant damage such as a decrease in productivity when continuously exposed. Therefore, generally, by ventilating through the opening of side windows and skylights in the greenhouse, hot air is discharged to the outside air, and cold outside air is allowed to flow in to control the temperature inside the greenhouse to an appropriate level. This is the typical thermal environment control method for current greenhouses.

[0003] However, such a control method has the drawback of ultimately wasting the useful solar radiation energy that could be utilized into the atmosphere.

[0004] Also, in the case of existing control methods, in order to maintain the greenhouse temperature at a certain level (5°C to 7°C or higher) so that crop damage does not occur when the temperature in the greenhouse drops significantly at night (dropping below zero in midwinter when there is no heating supply), various heating facilities (boilers, air heat pumps, water heat pumps, electric heaters, etc.) are operated for heating, resulting in a large energy consumption drawback.

Summary of the Invention

[0006] The present invention aims to provide a greenhouse solar heat pump heating and cooling system that uses solar radiation energy flowing into the greenhouse and heat generated by LEDs installed and operated on vertical beds as heat sources. [Means for solving the problem]

[0007] The greenhouse solar heat pump heating and cooling system according to the present invention, which solves the above-mentioned problems, is characterized by comprising: a greenhouse including a crop growing section which is a space in which crops grow and a heat source section located in a space separated from the crop growing section by a partition wall on one side; multi-tiered vertical beds and LED equipment provided in the crop growing section; a heat pump system arranged in the heat source section and driven using solar radiation energy accumulated inside the crop growing section and LED waste heat generated by the operation of the LED equipment as a heat source; a spraying system provided in the upper space of the crop growing section; a heat storage tank for storing hot or cold water obtained by driving the heat pump system; and a control unit that controls the driving of the LED equipment, the heat pump system and the spraying system.

[0008] Here, the upper part of the partition wall is provided with a first ventilation opening that can be opened to allow air from the crop growing area to flow into the heat source area.

[0009] Furthermore, the heat source unit is provided with a second vent that can be opened to allow air from outside the greenhouse to flow into the heat source unit.

[0010] The LED equipment is configured such that an LED substrate is placed inside an LED conduit, and one end of the LED conduit is equipped with a blower that supplies air to the LED conduit.

[0011] The spraying equipment may include a water supply pipe and a number of spray nozzles.

[0012] The heat storage tank is preferably located in the underground space below the greenhouse and has a distributed heat storage structure divided into multiple heat storage spaces.

[0013] One side of the crop growth section may be equipped with a fan coil unit that supplies heating heat from hot water or cooling heat from cold water stored in the heat storage tank to the crop growth section.

[0014] It is preferable that the LED equipment and the heat pump equipment operate using a regenerative power source as their power source.

[0015] On the other hand, when the internal temperature of the crop growth section exceeds the growth temperature conditions, the control unit supplies the solar radiation energy inside the crop growth section as a heat source on the evaporator side of the heat pump system to produce hot water, and supplies air cooled on the evaporator side of the heat pump system to the inside of the crop growth section.

[0016] Furthermore, if solar radiation energy is insufficient, the control unit can operate the LED equipment and supply the waste heat generated by the LEDs at that time as a heat source for the evaporator side of the heat pump equipment to operate the heat pump equipment.

[0017] Furthermore, the control unit can operate the LED equipment at midday during winter, and supply the waste heat generated by the LEDs at that time, along with solar radiation energy, as a heat source for the evaporator side of the heat pump equipment to operate the heat pump equipment.

[0018] Furthermore, it is preferable that the control unit operates the spraying equipment to lower the temperature of the air flowing from the crop growth section to the evaporator side of the heat pump equipment.

[0019] Here, the humid air that flows into the evaporator side of the heat pump equipment is recovered as water again through a condensation process, and the recovered water can be stored and then supplied back to the spray equipment.

[0020] The control unit can supply the warm water stored in the heat storage tank to the fan coil unit to dissipate heating heat in the crop growing section.

[0021] Then, the control unit can use the heating heat dissipated in the crop growing section as a heat source of the heat pump equipment to produce warm water.

[0022] Then, the control unit can operate the LED equipment and allow the air cooled through the evaporator side of the heat pump equipment to flow into the LED pipe.

[0023] Then, the control unit can supply the outside air of the greenhouse as a heat source of the condenser side of the heat pump equipment to produce cold water.

[0024] In addition, the control unit can supply the cold water stored in the heat storage tank to the fan coil unit to dissipate cooling heat in the crop growing section.

[0025] Then, the control unit can operate the LED equipment, and the LED exhaust heat generated at this time can be cooled by the cooling heat dissipated in the crop growing section.

[0026] Then, the control unit can supply the outside air of the greenhouse as a heat source of the condenser side of the heat pump equipment to produce cold water, and by supplying cooling heat into the crop growing section, replenish the cold air in the heat storage tank that is exhausted.

Advantages of the Invention

[0027] The greenhouse solar heat pump heating and cooling system according to the present invention operates the heat pump equipment using the solar radiation energy accumulated by the greenhouse effect inside the greenhouse as a heat source, so that the greenhouse can be cooled without ventilation, and at the same time, the heat source required for greenhouse heating can be stored.

[0028] Furthermore, if solar radiation energy is insufficient, the waste heat generated by the operation of the LED equipment can be recovered and used as an additional heat source.

[0029] Furthermore, by applying fogging cooling to prevent the air temperature inside the crop growing area from rising too high, the performance and durability of the heat pump equipment can be ensured.

[0030] Furthermore, since greenhouse thermal environment control through ventilation is not required, this method has the advantage of improving crop productivity through carbon dioxide fertilization while minimizing the influx of pathogens and viruses through the inflow of outside air.

[Modes for carrying out the invention]

[0032] The embodiments of the present invention will be described below with reference to the drawings. However, detailed descriptions of known functions and configurations that may unnecessarily obscure the gist of the present invention will be omitted.

[0033] Referring to Figures 1 and 2, according to the present invention, the greenhouse 1 is formed by dividing it into a crop growth section 100 in which crops grow within the internal space, and a heat source section 200 located as a separate space on one side of the crop growth section 100, in order to effectively utilize the solar radiation energy and LED waste heat flowing into the greenhouse. This section is where the heat pump equipment 210 is located.

[0034] A partition wall 10 is provided between the crop growth section 100 and the heat source section 200, and a first ventilation opening 11 is provided at the top of the partition wall 10, which can be opened to allow air from the crop growth section 100 to flow into the heat source section 200.

[0035] Furthermore, the heat source unit 200 is equipped with a second vent 12 that can be opened to allow air from outside the greenhouse 1 to flow into the heat source unit 200.

[0036] The crop growing section 100 is fitted with multi-tiered vertical beds 110, and LED equipment 120 is provided between the beds to supplement the photosynthesis that may be insufficient due to the application of multi-tiered beds. According to the present invention, the LED equipment 120 can be operated to induce photosynthesis when solar radiation energy is insufficient (for example, on cloudy days, snowy or rainy days), or even when solar radiation energy is sufficient, it can be operated to store as much heat as possible in the heat pump equipment 210 in preparation for extremely cold periods, in addition to solar radiation energy.

[0037] The LED equipment 120 is configured such that the LED substrate 121 is placed inside the LED piping 122, and the heat generated by the LEDs does not directly diffuse into the air inside the crop growth section 100 (ensuring uniformity of the crop heat growth environment), but is instead immediately discharged to the heat source section 200 by the air flowing through the LED piping 122. A blower 123 is provided at one end of the LED piping 122 to supply air to the LED piping 122.

[0038] The heat pump system 210 utilizes the greenhouse structure as a solar thermal energy trap and is driven by solar radiation energy accumulated inside the crop growing section 100 as a heat source. According to the present invention, in addition to solar radiation energy, the waste heat generated by the operation of the LED equipment 120 can also be used as a driving heat source for the heat pump system 210.

[0039] A spraying system 130 is provided at the top of the crop growing section 100. The spraying system 130 includes a water supply pipe 131 and numerous spray nozzles 132, and is used for operating the fogging cooling and heat pump system 210, which will be described later, at the optimal performance coefficient.

[0040] According to the present invention, the LED equipment 120 and the heat pump equipment 210 can be powered by renewable energy sources (e.g., solar power, wind power, etc.) installed on idle land that can be secured by applying a vertical bed.

[0041] On the other hand, the greenhouse solar heat pump heating and cooling system according to the present invention includes a heat storage tank 2 for storing hot or cold water obtained by driving the heat pump equipment 210.

[0042] Referring to Figure 3, according to the present invention, the heat storage tank 2 is provided in the lower underground space UG of the greenhouse 1, eliminating the need for a separate site for the installation of the heat storage tank 2. Furthermore, by being implemented in a distributed heat storage structure divided into multiple heat storage spaces 20, it is possible to prevent stratification of the temperature distribution within the heat storage space.

[0043] Between the thermal storage tank 2 and the heat pump equipment 210, there are pipes 21 and 23 that connect the thermal storage tank 2 to the condenser side and evaporator side of the heat pump equipment 210 so that the heat transfer medium of the thermal storage tank 2 can exchange heat with the condenser side and evaporator side of the heat pump equipment 210.

[0044] On one side of the crop growth section 100, a fan coil unit 30 is provided to supply heating or cooling heat stored in the heat storage tank 2 to the crop growth section 100. The fan coil unit 30 is connected to the heat storage tank 2 via piping 22 so that the heat transfer medium in the heat storage tank 2 can be circulated.

[0045] Although not shown in the drawings, the greenhouse solar heat pump heating and cooling system according to the present invention may include a pump that generates the flow of a heat transfer medium in the pipes 21, 22, and 23, and includes a control unit that controls the operation of a heat pump unit 210, an LED unit 120, a spray unit 130, a fan coil unit 30, a pump (not shown), a first vent 11, a second vent 12, etc.

[0046] Unexplained symbols 211 and 212 are pipes that supply air, which has been heat-exchanged with the evaporator or condenser side of the heat pump equipment 210, to the crop growing section 100 or discharge it to the outside of the greenhouse 1.

[0047] The greenhouse solar heat pump heating and cooling system according to the present invention, configured in this manner, can be controlled to switch between heating mode and cooling mode in the following manner.

[0048] Heating mode control

[0049] (1) Daytime When the internal temperature of the crop growth section 100 exceeds the appropriate growth temperature conditions (28°C or lower), the solar radiation energy inside the crop growth section 100 is supplied as a heat source to the evaporator side of the heat pump equipment 210, and the heat pump equipment 210 is put into operation (see Figure 4).

[0050] On cloudy days or when solar radiation energy is insufficient, the LED equipment 120 is activated to induce photosynthesis, and the waste heat generated by the LEDs at this time is supplied as a heat source on the evaporator side of the heat pump equipment 210 to operate the heat pump equipment 210 (see Figure 5).

[0051] Even if solar radiation energy is sufficient during the winter, the LED equipment 120 is operated to prepare for the coldest period, and the solar radiation energy and waste heat from the LEDs are supplied as a heat source to the evaporator side of the heat pump equipment 210 to operate the heat pump equipment 210 (see Figure 6).

[0052] To this end, by opening the first vent 11, the high-temperature air from the top inside the crop growth section 100 and / or the high-temperature air inside the LED piping 122 can flow into the heat source section 200 where the heat pump equipment 210 is located.

[0053] The air, which has been used as a heat source on the evaporator side of the heat pump equipment 210 and has cooled to a temperature of 5°C to 7°C, is supplied again to the lower end of the crop growth section 100 via the piping 211.

[0054] Here, the hot water (45°C to 50°C) that flows along the piping 21 and is heated by heat recovery on the condenser side of the heat pump equipment 210 is stored in the heat storage tank 2 for heating supply at night, etc.

[0055] Therefore, the inside of the heated crop growing section 100 (e.g., 33°C) is temporarily cooled (e.g., to 28°C), and at the same time, the accumulated solar radiation energy and / or LED waste heat in the greenhouse, which would otherwise be released into the atmosphere in existing systems, can be recovered, stored, and then utilized.

[0056] As a result, greenhouse thermal management control is realized that enables minimizing greenhouse ventilation by cooling the greenhouse air, along with supplying the heat source necessary to drive the heat pump for heating heat production.

[0057] Furthermore, since the heat pump can be operated with a high coefficient of performance (COP) using high-temperature air as a heat source (for example, if the temperature of the external heat source is below freezing or 5°C or below in winter, the heat pump cannot be operated), the energy saving effect is significant. Additionally, as the air re-inflowing into the crop growth section 100 passes through the evaporator side of the heat pump equipment 210, excess moisture can be condensed and removed, thus lowering the absolute humidity and resulting in the additional effect of lowering the relative humidity inside the crop growth section 100.

[0058] Furthermore, if the electricity required to operate the heat pump equipment 210 is generated from solar power that can be installed on idle land secured by the application of the vertical bed 110, it becomes possible to operate it in a carbon emission-controlled manner.

[0059] On the other hand, if the air temperature inside the crop growing section 100 rises too high (for example, above 40°C), problems may arise with the performance and durability of the heat pump equipment 210. In this invention, to solve such problems, the spraying equipment 130 is operated to perform fogging cooling using low relative humidity conditions inside the greenhouse, thereby controlling the temperature of the air flowing into the heat pump equipment 210 to an appropriate temperature (for example, around 30°C) in which the optimal performance coefficient can be obtained (see Figure 7).

[0060] When fogging cooling is applied, the air temperature decreases due to the evaporation of water, but the humid air containing the latent heat of evaporation releases the latent heat of condensation from the condensation of water on the evaporator side of the heat pump system 210 (i.e., the enthalpy of the air increases), so sufficient heat is supplied without putting undue strain on the compressor operation of the heat pump system 210. The humid air flowing into the evaporator side of the heat pump system 210 can be recovered as water through the condensation process, and after storing the recovered water, the process can be repeated by spraying within the crop growth area 100, thus enabling water conservation through water circulation. In addition, since there is also moisture in the air due to the transpiration of crops, there is an additional effect of recovering moisture from the air and reducing water usage.

[0061] (2)Night At night, the internal temperature of the crop growth section 100 is controlled to maintain an appropriate level using heating water (45-50°C) that has been stored during the day using solar radiation energy and / or LED waste heat.

[0062] To achieve this, heating water stored in the heat storage tank 2 is supplied to the fan coil unit 30, and the fan coil unit 30 blows high-temperature air, which has exchanged heat with the heating water, towards the bed 110 (see Figure 8).

[0063] Although not shown in the illustration, in another embodiment, heating heat can be supplied by radiation and natural convection through hot water pipes installed in each bed 110, without using the fan coil unit 30.

[0064] On the other hand, if the energy stored during winter nights falls below a certain level, the system can be controlled to an emergency operation mode that corresponds to the peak heating load corresponding to the greenhouse heating load by sacrificing the diffused heating heat within the crop growth section 100 as a heat source for the heat pump equipment 210 to produce high-temperature water (see Figure 9). Here, if necessary, additional photosynthesis can be induced by operating the LED equipment 120, and the waste heat from the LEDs can be further utilized as a heat source (see Figure 10).

[0065] When the LED equipment 120 is in operation, it is preferable to increase the amount of heat dissipated by the LEDs and improve the LED light efficiency by directing the cooled air, which has passed through the evaporator side of the heat pump equipment 210, into the LED piping 122 instead of supplying it to the crop growth section 100, thereby promoting heat dissipation from the LEDs (see Figure 11).

[0066] Control of cooling mode

[0067] (1)Night During periods other than midday in the summer, outside air from the greenhouse is supplied as a heat source for the condenser side of the heat pump system 210 to operate the heat pump system 210 (see Figure 12).

[0068] To this end, by opening the second vent 12, outside air from the greenhouse can flow into the heat source section 200 where the heat pump equipment 210 is located.

[0069] The first ventilation opening 11 is kept closed to avoid any impact on the crop growth area 100.

[0070] The air, whose temperature has risen after being used as a heat source on the condenser side of the heat pump equipment 210, is discharged again to the outside of greenhouse 1 through piping 212.

[0071] Here, the chilled water (7°C to 9°C) that flows along the piping 23 and is cooled by the heat discharge on the evaporator side of the heat pump equipment 210 is stored in the heat storage tank 2 for cooling supply during the daytime.

[0072] On the other hand, if some supplemental lighting is required due to daytime light interference at the lower end of the bed, the LED equipment 120 is operated at night to induce photocombination. The heat generated by the LEDs at this time can be cooled by the cool air produced by the cooling operation of the heat pump equipment 210 (see Figure 13).

[0073] Although not shown in the illustration, in another embodiment, the heat generated by the LEDs can also be discharged to the outside of the greenhouse 1 through LED piping 122 connected to the outside air of the greenhouse.

[0074] (2) Daytime If cooling is required at midday due to a rise in room temperature caused by the influx of solar radiation energy, the cool air stored overnight is supplied via the fan coil unit 30 to perform the cooling (see Figure 14).

[0075] Although not shown in the illustration, in another embodiment, cooling heat can be supplied by radiation and natural convection through chilled water piping installed in each bed 110, without using the fan coil unit 30.

[0076] On the other hand, in the summer, the intensity of solar radiation energy increases and the cooling load increases sharply, so the stored cold air alone may not be enough to create suitable temperature conditions for growth. Therefore, the heat pump equipment 210 can be operated to simultaneously replenish the cold air that is consumed by the cooling supply (see Figure 15).

[0077] Although embodiments of the present invention have been described in detail above with reference to the accompanying drawings, the embodiments disclosed herein and in the accompanying drawings are used solely for the purpose of facilitating the technical idea of ​​the present invention and are not used to limit the scope of the present invention as described in the claims. Therefore, a wide variety of modifications and equivalent other embodiments are possible for those who are ordinary skill in the art. [Explanation of Symbols]
