Hereinafter, with reference to the accompanying drawings will be described in more detail a thermo-magnetic compound heating device according to a preferred embodiment of the present invention.

1 is an installation and configuration diagram of a mechanism and an accessory of the apparatus according to the present invention.

The single greenhouse 1 is the greenhouse which is installed on the outermost side, and the outside is composed of transparent vinyl or glass.

The double-greenhouse 2 is installed inside the single-greenhouse 1, and has a switchgear 6a, which can be opened and closed during the day, and the light-shielding vinyl 6 opened and closed by the switchgear 6a is 2 It consists of a reflective film with no outflow of air reflecting light up to 30 to 70% to the outside of the middle temperature chamber (2).

Heat-extruder (3) is installed inside the dual temperature chamber (2), the cooling / heating / arranged in series on the suction or discharge side of the blower (3d) and the blower (3d) which can control the air volume according to the internal temperature It consists of one side heat exchanger 3a, two side heat exchanger 3b, and three side heat exchanger 3c which can select a dehumidification function. The heat extractor 3 absorbs heat at the same time as cooling during the day, and discharges heat at the same time as heating at night. An important part of the present invention is a device that primarily absorbs energy to enable heating and heating in a greenhouse at a magnetically heating level. The heat exchanger in the heat exchanger (3) cools / heats the air in the greenhouse by using the temperature difference between the air in the greenhouse and the hot and cold water circulating in the heat exchanger tube, so that the water circulating in the heat exchanger is heated. Cooled.

The cold storage unit 8 includes a cold storage tank 8a for storing cold water, a cold water pump 8b for circulating cold water to the evaporator 7d of the heat pump, and an evaporator outlet pipe 8c. Cold water supplied to the heat extractor (3) from the bottom of the cold storage tank (8a) cools the greenhouse at a high temperature and absorbs the heat energy, and thus the cold water whose temperature rises increases the cold water recovery pipe (10b) to the top of the cold storage tank (8a). Come back through. The water temperature difference between the upper part and the lower part of the storage cooling tank 8a is about 5 ° C or more during the greenhouse cooling operation, and may be largely 10 ° C or more. The water storage capacity of the cold storage tank 8a is 2 to 6 tons per 1RT of the heat pump capacity or a capacity to store all the cooling water produced when the heat pump system 7 is operated for 24 hours.

The heat storage unit 9 includes a heat storage tank 9a for storing hot water, a hot water pump 9b for supplying hot water to the condenser 7b, and a condenser outlet pipe 9c. The heat pump system 7 is operated to transfer the heat of the heat storage tank 8a to the heat storage tank 9a. The hot water is sucked into the hot water pump 9b from the bottom of the heat storage tank 9a to absorb heat through the heat pump condenser 7b and circulate to the top of the heat storage tank 9a. The water temperature difference between the upper and lower portions of the heat storage tank 9a is about 5 ° C or more during greenhouse heating operation, and may be largely 10 ° C or more. The water storage capacity of the heat storage tank 9a is composed of 1 to 3 tons per 1RT of the heat pump capacity.

The heat pump system 7 includes a refrigerant pipe 7e through which the compressor 7a communicates with the refrigerant, a condenser 7b through which the refrigerant is condensed, an expansion valve 7c for expanding the refrigerant, and an evaporator through which the refrigerant evaporates ( 7d) and the like.

The heat pump system 7 is a facility for moving a part of heat containing cold water toward hot water, and the heat of cold water absorbs the heat energy of the sun introduced into the greenhouse during the day using the heat extractor 3. Since the temperature of the cold water heated by the heat inside the winter greenhouse is higher than the night greenhouse temperature, the heated cold water is used as heating water at night without any heat transfer. If the cold water temperature is lowered by direct heating and the cold water temperature becomes impossible for direct heating, the heat pump system (7) is operated to lower the cold water temperature further and this heat is transferred to hot water and used for heating. Therefore, the heat supply capacity of the heat pump is very low, which is 30-50% of the total supply calorie load supplied by the complex air-conditioning unit provided by the present invention. In the case of spring and autumn, when the temperature of the greenhouse is not high enough to use the cold water as heating water, the cold water flow into the greenhouse is stopped and the heat pump system 7 is continuously operated to cool the cold water in the cold storage tank 8a the next day. This temperature is reduced to around 7 degrees. Therefore, the cooling capacity of the heat pump system 7 is not determined as the maximum cooling load at the moment of the day, but the daily total cooling load is determined as the capacity that can be achieved by operating the heat pump for 24 hours.

Cold water circulation device (10, 10a, 10b) is composed of a cold water circulation pump 10, cold water supply pipe (10a) and cold water recovery pipe (10b). Cold water is supplied from the cold storage tank (8a) to the heat extractor (3) and the near-field heating facility (5) through the cold water circulation pump (10) and circulated back to the cold storage tank (8a).

The hot water circulation device 11, 11a, 11b is composed of a hot water circulation pump 11, hot water supply pipe (11a) and hot water recovery pipe (11b). The hot water is supplied from the heat storage tank (9a) to the heat extractor (3) and the near-field heating facility (5) through the hot water circulation pump (11), and when the heat exchange is complete, the heat storage tank (9a) again through the hot water recovery pipe (11b). Return to

Upper and lower portions of the cold storage tank 8a are respectively provided with a cold water header 8d capable of connecting pipes to the heat pump system 7 and the heat extractor 3 of the greenhouse. Each cold water header 8d is provided with a plurality of water distribution pipes 23 so as to minimize vortex formation due to the inflow and outflow of water, and forms a plurality of holes in each water distribution pipe 23. The cold water header 8d is not provided with a hole other than the provision of the water distribution pipe 23.

Heat storage tank (9a) is also located in the upper and lower heat pump system (7) and the hot water header (9d) that can connect the pipes flowing in and out respectively into the heat inlet and outlet (3) of the greenhouse, respectively. Each hot water header 9d is provided with a plurality of water distribution pipes 23 so as to minimize vortex formation due to the inflow and outflow of water, and forms a plurality of holes in each water distribution pipe 23. The hot water header 9d is not provided with a hole other than the provision of the water distribution pipe 23.

When the cold water pump 8b and the cold water circulation pump 10 are operated at the same time, the water discharged from the evaporator outlet pipe 8c to the cold storage tank 8a does not flow into the possible cold storage tank 8a, but directly to the cold water circulation pump 10 ) Directly flows into the cold water pump (8b) without being introduced into the cold storage tank (8a), and the water discharged from the cold water recovery pipe (10b) to the cold storage tank (8a) in the same manner. The heat pump system 7 and the heat extractor are configured by connecting connecting nozzles 24 at both ends of each cold water header 8d so as to be supplied from the cold storage tank 8a or discharged to the cold storage tank 8a only by the difference in discharge amount. Connect the pipes to be connected in (3).

The cold water header 8d and the hot water header 9d have the same structure as shown in FIG.

This connection method is similar to connecting the pipes connecting the heat pump system 7 and the heat extractor 3 to the heat pump system 7 illustrated in FIG. 3 first, and then connecting the connection site to one direction of the cold water header 8d. It looks different but shows different operation results. In this case, an operation result similar to that of the cold water pump 8b and the cold water circulation pump 10 is connected in series. As a result, the outflow and inflow of water to be supplied or discharged from the cold storage tank 8a due to the capacity difference of the two pumps is significantly reduced and the thermal efficiency is reduced.

The suction side of the cold water pump 8b is connected to one side of the upper cold water header 8d of the cold storage tank 8a, and the evaporator outlet pipe 8c is connected to one side of the cold water header 8d below the cold storage tank 8a. In addition, since the difference in water temperature between the upper and lower portions of the cold storage tank 8a is about 5 to 10 ° C. or more, the cold water of the cold storage tank 8a is used for cooling purposes and when it is used for heating purposes. The position of the cold water header 8d connected to the supply pipe 10a and the cold water recovery pipe 10b is reversed. Accordingly, both the cold water supply pipe 10a and the cold water recovery pipe 10b are configured to be connected to the upper and lower cold water headers 8d, and the suction side change valves 20a and 20b and the discharge destination change valves 22a are formed in the respective pipes. , 22b).

That is, when cold water is used for cooling, the cold water supply pipe 10a is connected to the other side of the lower cold water header 8d, and the cold water recovery pipe 10b is connected to the other side of the upper cold water header 8d, and the cold water is When used for heating, the cold water supply pipe (10a) is connected to the other side of the upper cold water header (8d) and the cold water recovery pipe (10b) is connected to the other side of the cold water header (8d) of the lower.

When the hot water pump 9b and the hot water circulation pump 11 are operated at the same time, the water discharged from the condenser outlet pipe 9c to the heat storage tank 9a does not flow into the possible heat storage tank 9a, but directly to the hot water circulation pump 11. Directly introduced, the water discharged from the hot water recovery pipe (11b) to the heat storage tank (9a) in the same manner is not directly introduced into the possible heat storage tank (9a), but directly flows into the hot water pump (9b), only the difference between the respective intake and discharge amount Each hot water header 9d is connected to the heat pump system 7 and the heat extractor 3 by forming a connection nozzle 24 at each end to be supplied from the heat storage tank 9a or discharged to the heat storage tank 9a. Connect with piping.

This connection method is similar to the first connection of the pipe connecting the heat pump system 7 and the heat extractor 3 illustrated in FIG. 3, and then the connection portion thereof in one direction of the hot water header 9d. It looks different but shows different operation results as described above.

The suction side of the hot water pump 9b is connected to one side of the lower heat storage header 9d and the hot water header 9d, and the condenser outlet pipe 9c is connected to the one side of the heat storage tank 9a and the upper hot water header 9d. The hot water supply pipe 11a is connected to the other side of the upper hot water header 9d, and the hot water recovery pipe 11b is connected to the other side of the lower hot water header 9d.

The cold water inlet valves 12a, 12b, 12c, and 12d are water pipes branched from the cold water supply pipe 10a and respective heat exchangers 3a, 3b, 3c in the heat extractor 3, and near-heat heating equipment 5 It is installed at the inlet side of the valve, and it is a valve to block or open the flow of cold water.

The cold water outlet valves 13a, 13b, 13c, and 13d are connected to the outlet side of each of the heat exchangers 3a, 3b, 3c and the near-area heating system 5 and the cold water recovery pipe 10b in the heat exchanger 3. Installed at the site, it is a valve to block or open the flow of cold water.

The hot water inlet valves 14a, 14b, 14c and 14d are the water pipes branched from the hot water supply pipe 11a and the respective heat exchangers 3a, 3b and 3c in the heat extractor 3 and the near-field heating equipment 5 It is installed at the inlet side of the connection, it is a valve to block or open the flow of hot water.

The hot water outlet valves 15a, 15b, 15c, and 15d are connected to the outlet side of each of the heat exchangers 3a, 3b, and 3c and the near-area heating system 5 and the hot water recovery pipe 11b in the heat extractor 3. It is installed at the site and is a valve to block or open the flow of hot water.

Cold water inlet valves 12a, 12b, 12c, 12d, cold water outlet valves 13a, 13b, 13c, 13d, hot water inlet valves 14a, 14b, 14c, 14d, hot water outlet valves 15a, 15b, 15c, 15d ) Is commonly connected to the heat exchanger (3) and the near-heat heating system (5), so that the hot water side valve and the cold water side valve must not be open at the same time to the same heat exchanger or the near-air heating system (5) in the heat-extruder (3). . In addition, when opening and closing, the inlet and outlet should be operated in the same valve position in pairs. For example, since the cold water inlet valve 12a, the cold water outlet valve 13a, the hot water inlet valve 14a, and the hot water outlet valve 15a are commonly connected to the one-side heat exchanger 3a, the cold water circulation operation is performed. The inlet valve 12a and the cold water outlet valve 13a should be opened, and the hot water inlet valve 14a and the hot water outlet valve 15a should be closed. On the contrary, during the hot water circulation operation, the cold water inlet valve 12a and the cold water outlet valve 13a should be closed, and the hot water inlet valve 14a and the hot water outlet valve 15a should be opened.

The single-chamber exhaust fan 16 is used to replace the internal air of the single-chamber 1 with external air, and during operation, air is introduced from the single-chamber intake window 17 so that the single-chamber exhaust fan ( 16) is exhausted. The primary greenhouse intake window 17 is automatically opened when the primary greenhouse exhaust fan 16 operates and a filter is installed to prevent contamination from the outside.

The double-walled room intake fan 18 is installed on the outer wall of the double-greenhouse room 2 and the double-sided room 2 exhaust side window 19 is formed on the opposite side of the side on which the double-room intake fan 18 is installed. When the intake fan 18 is operated, the air of the intake amount is automatically discharged out of the duplex chamber 2 through the exhaust side window 19.

The air distributor 4 is a facility for uniformly supplying cooling / heating air to the inside of the dual greenhouse 2.

Near-zone heating equipment (5) is a facility for supplying cold or hot water for heating and cooling the roots of crops.

The auxiliary cooling device 21 reduces the heating load after the winter season and further increases the cooling load, so that the temperature of the heat storage tank 9a rises to 38 degrees or more during the daily operation cycle, thereby effectively moving the heat in the heat pump system 7. If it can not be performed is a device for circulating and cooling the hot water of the heat storage tank (9a), it can be configured as an air-cooled cooling tower.

Specific embodiments of the present invention are as follows. This is based on a 1,500 square meter strawberry greenhouse. This description is based on the configuration of FIG. 1.

The optimal temperature for strawberry growth is 25 degrees during the day and 10 degrees at night, and the optimal temperature for roots is around 18 degrees during the day and 10 degrees at night. If the night temperature falls below 5 degrees, the growth can be extremely sluggish, and if the daytime temperature exceeds 30 degrees, the crop growth is adversely affected. Managing night temperatures around 10 degrees is beneficial for strawberry growth. Humidity is appropriate around 60 ~ 70% relative humidity, and if too dry or too humid, it can be a disease such as powdery mildew or mildew, so proper humidity management is necessary.

The capacity of the heat pump system 7 is 30,000 Kcal / hr based on the cooling capacity, and the required power is 10 KW. This is a typical heat pump with a coefficient of performance (COP) 3.5. In order to specifically illustrate the operating temperature, the present description refers to a general heat pump using ammonia or freon gas as a refrigerant. When the refrigerant becomes carbon dioxide, its operating temperature may vary and the contents of the present invention are not affected by the selection of the refrigerant of the heat pump, and the same may be applied to all heat pumps.

The capacity of the heat storage tank 9a is 15 m 3, and the capacity of the heat storage tank 8a is 30 m 3. The capacity ratio of the heat storage tank 9a and the heat storage tank 8a is set to 1: 2. The reason is that in the case of the winter season that requires heating, the cooling time is shorter than the heating time, so the cooling and the subsequent heat absorption of cold water must be completed in a short time.

Since the thermomagnetic-type composite air conditioner according to the present invention is a device dependent on solar radiation heat, the cooling and heating are repeatedly performed based on 24 hours, which is the rotation cycle of the earth. Sunrise time changes slightly each day, but a similar form of driving repeats 24 hours at sunrise.

The heating and cooling needs for greenhouses are winter, spring and autumn. Driving methods in spring and autumn are the same.

The description of the operation mode will be described in the embodiment divided into winter and spring. Winter is based on the coldest January and spring is the last time you need heating and cooling.

■ winter driving

Operation mode is cooling mode that cools greenhouse with cold water, dormant mode that does not require heating and cooling, combined heating mode that uses both heated cold water and hot water, and heats cold water to hot water using a heat pump to use only hot water. Heating is divided into single heating mode. Repeat the operation sequentially in these four modes every day.

1) cooling mode

The cooling mode starts when the sun's altitude rises and the greenhouse temperature exceeds 22 degrees, from the time the greenhouse temperature drops below 25 degrees due to reduced solar radiation, roughly from 10 am to 3 pm.

Both the cold water of the heat storage tank 8a and the hot water of the heat storage tank 9a are cooled by the heating operation the day before. The temperature of cold water is 7 degrees, the temperature of hot water is around 22 degrees, the temperature inside the greenhouse is 22 degrees, and the temperature of strawberry roots is about 10 degrees.

When the temperature inside the greenhouse rises due to the increase in the solar altitude, the cold water inlet valves 12a, 12b, 12c and the cold water outlet to supply cold water to all of the one-side heat exchanger 3a, the two-side heat exchanger 3b, and the three-side heat exchanger 3c. Open the valves 13a, 13b, 13c. The cold water circulation pump 10 and the blower 3d are operated to circulate the air in the greenhouse and start cooling.

The surplus solar radiation introduced into the greenhouse is absorbed by cold water flowing through the one-side heat exchanger 3a, the two-side heat exchanger 3b, and the three-side heat exchanger 3c, and the temperature of the greenhouse is maintained at 30 degrees or less. Water vapor generated by the transpiration of strawberries is condensed outside the one-side heat exchanger 3a, the two-sided heat exchanger 3b, and the three-sided heat exchanger 3c. Cold water flowing inside the heat exchanger absorbs heat and gradually increases in temperature. At this time, the heat pump system 7 is operated to lower the temperature of the cold water. About 25% of the heat absorbed is transferred to the hot water by a heat pump and the remaining heat remains in the cold water.

The greenhouse temperature begins to drop slightly at 1:27 pm and begins to drop below 25 degrees around 3 pm. The heat pump operates for 5 hours, and the amount of heat transferred to water through the one-side heat exchanger (3a), two-sided heat exchanger (3b), and three-sided heat exchanger (3c) is 600,000Kcal, and the power is converted into heat according to the operation of the heat pump. 643,000 kcal, including kcal, is delivered to hot and cold water. The heat pump runs 193,000 kcal of the 643,000 kcal to hot water, while the remaining 450,000 kcal is stored in cold water.

During this period, part of the hot water is supplied to the root zone heating equipment 5 to raise the temperature of the strawberry roots. To this end, the hot water inlet valve 14d and the hot water outlet valve 15d are opened.

The cold water temperature is 22 degrees and the hot water temperature is 32 degrees when the heat pump system 7 is operated and the cold water circulation is stopped in the heat extractor 3.

2) dormant mode

After the cooling mode is in operation, the temperature of the greenhouse naturally falls to around 15 degrees without affecting the growth of strawberries without additional heat supply or heat emission, and is about 7 pm. There is no separate heating or cooling operation in the greenhouse air. The root zone heating equipment 5 maintains hot water circulation to prevent the root temperature from dropping. Do not run the heat pump during idle mode.

3) composite heating mode

The temperature of the greenhouse drops sharply after sunset, thus heating starts. Heating uses both warm hot water as well as hot water. The temperature of the cold water is maintained at 22 degrees after the completion of the cooling mode, which can be useful for heating. However, cold water and hot water are not mixed, but are heat exchanged through a separate heat exchanger. The start of heating starts around 10 pm when the greenhouse temperature drops below 13 degrees. The term composite means the heating box using both hot and cold water.

One side heat exchanger 3a and two side heat exchanger 3b open cold water inlet valves 12a and 12b and cold water outlet valves 13a and 13b for cold water circulation. Since the difference in the water temperature of the upper and lower portions of the cold storage tank 8a is about 5 to 10 ° C. or more, the upper cold water of the cold storage tank 8a is supplied so that the upper cold water of the high storage cooling tank 8a is supplied. Open the suction side change valve 20b so as to flow into the one side heat exchanger 3a and the two side heat exchanger 3b, and adjust it to the upper direction of the cold storage tank 8a, and after the heat exchange, the cold water is lowered in the cold storage tank 8a. Open the discharge destination change valve (22b) so that it flows in.

The intake and drainage directions of the suction side change valves 20a and 20b and the discharge destination change valves 22a and 22b in the combined heating mode are opposite to those in the cooling mode and the single heating mode in which the heat pump is operated.

The three-sided heat exchanger 3c opens the hot water inlet valve 14c and the hot water outlet valve 15c for hot water circulation. Next, the blower 3d is operated to start greenhouse heating. Roots of strawberries are kept at low temperature at night, not only the roots, but also beneficial to the overall growth of the strawberries, so the heating system 5 changes to cold water circulation. To this end, the cold water inlet valve 12d and the cold water outlet valve 13d are opened.

The combined heating mode is maintained until the difference between the cold water and the greenhouse temperature is less than 4 degrees due to the drop in temperature of the cold water due to heating, and the time is about 5 am. At the end of the combined heating mode, the cold water temperature is 12 degrees, the hot water temperature is 18 degrees, and the greenhouse temperature is 8 degrees. The heat pump is not operated during this combined heating mode.

4) single heating mode

As stated above, when the temperature difference between the cold water and the greenhouse becomes less than 4 degrees, the heat exchange rate is lowered, so that the effective heat exchange is difficult. However, the cold water temperature of 12 degrees is not only a temperature that can transfer heat to the hot water when the heat pump is used. To transfer the heat of cold water to hot water and continue heating operation using hot water.

In order to operate the heat pump system 7, the intake and drainage directions of the suction side change valves 20a and 20b and the discharge destination change valves 22a and 22b must be adjusted in the opposite manner to those in the combined heating mode. The reason for this is to allow the cold water in the lower part of the cold storage tank 8a having a low temperature to be supplied because the temperature difference between the upper and lower portions of the cold storage tank 8a is about 5 to 10 ° C. or more. That is, the suction side change valve 20a is opened to adjust the lower cold water portion of the cold storage tank 8a to the one side heat exchanger 3a and the two side heat exchanger 3b to the lower direction of the storage cold tank 8a. Then, the discharge destination change valve 22a is opened and adjusted in the upper direction of the storage cooling tank 8a so that the cold water after the heat exchange flows into the upper portion of the storage cooling tank 8a.

The heat pump system 7 is operated and the cold water inlet valve 12a and the cold water outlet valve 13a are opened for circulation of the cold water in one side heat exchanger 3a. Although cold water is circulated in the one-side heat exchanger 3a, since the cold water temperature is lowered by the operation of the heat pump system 7, there is little heating effect by the one-side heat exchanger 3a, and the operation of the heat pump system 7 continues. The temperature of cold water is lower than the temperature of the greenhouse, thus exerting the effect of dehumidification.

The two-sided heat exchanger 3b and the three-sided heat exchanger 3c open the hot water inlet valves 14b and 14c and the hot water outlet valves 15b and 15c for hot water circulation. Then, the blower 3d is operated.

The roots of the strawberry should be maintained at 18 degrees during the day and the temperature should be raised early in the morning for active photosynthesis, so 2 hours after the operation of the single heating mode, the root heating equipment 5 changes to hot water circulation. To this end, the hot water inlet valve 14d and the hot water outlet valve 15d are opened.

The next step in the single heating mode is the morning when photosynthesis is actively active, so dehumidification in the single heating mode, which begins early in the morning and ends in the morning, is essential for effective photosynthesis, in addition to preventing disease caused by over-humidity. As stated above, some dehumidification occurs in the one-side heat exchanger 3a, but the dual-chamber intake fan 18 is operated to perform this more effectively. As a result, dry air existing between the first greenhouse (1) and the double greenhouse (2) flows into the dual greenhouse (2), and the humid air in the double greenhouse (2) opens the double greenhouse greenhouse exhaust window (19). Through the same amount is discharged. This humid air is in contact with the outer wall of the primary greenhouse 1 and the moisture condenses to become dry air and circulates through the dual greenhouse intake fan 18 to the dual greenhouse 2. In the case of the size of the greenhouse illustrated here, the outer wall of the single-room greenhouse (1) has an area of at least 3,000 square meters and the outside air temperature is at least 10 degrees lower than the inside of the greenhouse, so it can be dehumidified very effectively.

The single heating mode is about 5 hours until 10 am at which time the heat pump system 7 is turned on. The temperature of cold water, hot water, greenhouse and roots at the time of the end of the single heating mode is 7 degrees, 22 degrees, 20 degrees and 15 degrees, respectively. The temperature of cold water and hot water discharges all the heat absorbed in the cooling mode the whole day into the greenhouse, is reduced to the optimum temperature for the cooling mode operation, and rises to the optimum temperature for the temperature of the root and the photosynthesis of the greenhouse.

5) Thermal Efficiency (COP)

During winter operation, the heat pump system 7 having a capacity of 10KW is operated for 10 hours a day, so the total power is 100KWH / day, which is 86,000 Kcal / day of calorie conversion. The amount of heat used for cooling is 600,000 Kcal / day in the morning cooling mode, and the amount of heat used for heating is 686,000 kcal / day in the combined and single heating mode. This 686,000 Kcal is the sum of 600,000 Kcal of heat absorbed during cooling mode operation and 86,000 Kcal of electric energy converted into thermal energy by the operation of heat pump system (7). Therefore, the total heating and cooling use heat amount is 1,290,000 Kcal / day, the heat conversion of the total input power is 86,000 Kcal / day, so the thermal efficiency (COP) is 15. It has a thermal efficiency four times better than COP 3.5 of conventional geothermal heat pumps.

Spring driving

Spring driving is similar in concept to winter driving, but the average temperature in the greenhouse increases and daytime solar radiation increases, so some driving methods change.

The operation mode is divided into a cooling mode for cooling the greenhouse with cold water, a pause mode without requiring heating and cooling, and a single heating mode in which the heat of cold water is moved to hot water using a heat pump to heat using only hot water. Repeat the operation sequentially in these three modes every day. This is the lack of the combined heating mode in winter. In practice, the combined heating mode is gradually decreasing as the temperature rises. This example is based on the absence of the combined heating time.

1) cooling mode

It starts from the point when the greenhouse temperature exceeds 22 degrees, and decreases the radiant heat to the time when the greenhouse temperature falls below 27 degrees, approximately from 9 am to 2 pm.

Both the cold water of the heat storage tank 8a and the hot water of the heat storage tank 9a are cooled by the heating operation the day before. The temperature of cold water is 7 degrees, the temperature of hot water is about 28 degrees, the temperature inside the greenhouse is 22 degrees, and the temperature of strawberry roots is about 10 degrees.

As the sun's altitude rises, the temperature inside the greenhouse rises. Open the cold water inlet valves 12a, 12b, 12c and the cold water outlet valves 13a, 13b, 13c to supply cold water to all of the one-side heat exchanger 3a, the two-side heat exchanger 3b, and the three-side heat exchanger 3c. . Then, the blower 3d is operated to circulate the air in the greenhouse and start cooling.

The surplus solar heat energy introduced into the greenhouse is absorbed by cold water flowing through the one-side heat exchanger 3a, the two-side heat exchanger 3b, and the three-side heat exchanger 3c, and the temperature of the greenhouse is maintained at 30 degrees or less. Water vapor generated by the transpiration of strawberries is condensed outside the one-side heat exchanger 3a, the two-sided heat exchanger 3b, and the three-sided heat exchanger 3c. The heat pump system 7 is operated to lower the temperature of the cold water. About 25% of the heat absorbed is transferred to the hot water by a heat pump and the remaining heat remains in the cold water.

When the sun's altitude rises and the amount of light of the sun exceeds 40,000 lux, the retractable light-shielding vinyl 6 located at the upper part of the double greenhouse 2 is closed using the switch 6a. In the case of strawberries, the light saturation point is 20,000 ~ 40,000 lux, so the light does not help photosynthesis and only increases the temperature inside the greenhouse.

As the heat pump system 7 operates, the temperature of the hot water increases due to the heat transferred to the hot water. In the initial operation, the temperature of the hot water is 28 degrees, so it reaches 31 degrees after about 2 hours of operation. Since the temperature limit of the hot water is 38 degrees when the refrigerant of the heat pump system 7 is ammonia or freon gas, when the temperature of the hot water of the heat storage tank 9a reaches 32 to 33 degrees, the hot water is cooled by using an auxiliary cooling tower. The hot water temperature discharged from the condenser 7b is controlled to 37 degrees or less.

The greenhouse temperature starts to drop slightly at 1:27 pm and drops below 25 degrees around 3 pm. The heat pump operates for 5 hours, and the amount of heat transferred to water through the one-side heat exchanger (3a), two-sided heat exchanger (3b), and three-sided heat exchanger (3c) is 600,000Kcal, and the power is converted into heat according to the operation of the heat pump. 643,000 kcal, including kcal, is delivered to hot and cold water. The heat pump runs 193,000 kcal out of the 643,000 kcal to hot water, and 78,000 Kcal out of the 193,000 kcal is discharged to the outside by the cooling tower. 450,000 kcal is stored in cold water, except 193,000 Kcal, which is moved to hot water by heat pump operation.

During this period, part of the hot water is supplied to the root zone heating equipment 5 to raise the temperature of the strawberry roots. To this end, the hot water inlet valve 14d and the hot water outlet valve 15d are opened.

The cold water temperature at the time of stopping the heat pump operation and the heat extraction / exiter 3 operation is 22 degrees on average, and the hot water temperature is 36 degrees on average.

2) dormant mode

After the cooling mode is in operation, the temperature of the greenhouse naturally drops to around 15 degrees without affecting the growth of strawberries without additional heat supply or heat emission, until about 6 pm. There is no separate heating or cooling operation in the greenhouse air. The root zone heating equipment 5 maintains hot water circulation to prevent the root temperature from dropping.

The openable light-shielding vinyl 6 located at the upper part of the double greenhouse 2 is opened using the open / close device 6a. By operating the single-chamber exhaust fan 16, the outside air flows into the single-chamber 1 through the single-chamber intake window 17 to ventilate the single-chamber 1. Do not run the heat pump during idle mode.

3) single heating mode

The openable light shielding vinyl 6 located at the upper part of the double greenhouse 2 is closed using the switch 6a. In the cooling mode, since the temperature difference between the heated cold water and the greenhouse is not large, the heat exchange rate is low, and thus effective heat exchange is difficult. Therefore, the cold water heated to 22 degrees, the heat pump is used to transfer heat to the hot water to heat the hot water and at the same time cool the temperature of the cold water. This is to ensure low temperature cold water in the cooling mode, which is the next operation mode. Since a large capacity heat pump is required to cool the rapidly heated daytime greenhouse only with the heat pump system 7, the present invention effectively cools the room at a short time by using precooled cold water the night before. If there is no cold water storage, the capacity of the heat pump system 7 should be at least three times the capacity according to the present invention in order to have the same cooling load.

The one side heat exchanger 3a, the two side heat exchanger 3b, and the three side heat exchanger 3c open the hot water inlet valves 14a, 14b, 14c and the hot water outlet valves 15a, 15b, and 15c for hot water circulation. Then, the blower 3d is operated to circulate and heat the air in the greenhouse.

Roots of strawberries are kept at low temperature at night, not only the roots, but also beneficial to the overall growth of the strawberries, so the heating system 5 changes to cold water circulation. To this end, the cold water inlet valve 12d and the cold water outlet valve 13d are opened.

The next step in the single heating mode is morning, where photosynthesis is actively active, so dehumidification in the single heating mode, which ends in the morning, is essential for effective photosynthesis, in addition to preventing disease caused by over-humidity. Next, the double greenhouse intake fan 18 is operated. As a result, dry air existing between the first greenhouse (1) and the double greenhouse (2) flows into the dual greenhouse (2), and the humid air in the double greenhouse (2) opens the double greenhouse greenhouse exhaust window (19). Through the same amount is discharged. This humid air is in contact with the outer wall of the primary greenhouse 1 and the moisture condenses to become dry air and circulates through the dual greenhouse intake fan 18 to the dual greenhouse 2. Here, the size of the illustrated greenhouse is 15,000 square meters and in this case, the outer wall of the single-room greenhouse 1 has an area of at least 3,000 square meters, so the temperature of the outside air is at least 7 degrees lower than that of the inside of the greenhouse. have.

The single heating mode is about 15 hours from 5 pm to 8 am the next day, at which time the heat pump system 7 is turned on. The temperature of cold water, hot water, greenhouse and roots at the time of the end of the single heating mode is 7 degrees, 28 degrees, 18 degrees, 12 degrees, respectively. The temperature of cold water and hot water is discharged to the greenhouse and outside all the heat absorbed in the cooling mode the day before, and is reduced to the optimum temperature for the cooling mode operation.

4) Thermal Efficiency (COP)

During the spring operation, the heat pump system 7 with a capacity of 10KW is operated for 20 hours a day, so the total power is 200KWH / day, which is 172,000 Kcal / day. The heat used for cooling is 600,000kcal / day in the morning cooling mode and the heating calorie is 702,000kcal / day. This 702,000kcal is a limit of 78,000Kcal emitted to the outside in excess of calories from the sum of 600,000Kcal of heat absorbed during cooling mode operation and 180,000Kcal of heat converted from electric energy into heat energy according to the operation of the heat pump system (7). Therefore, the total heating and cooling use heat amount is 1,302,000Kcal / day, the heat conversion of the total input power is 172,000Kcal / day, the thermal efficiency (COP) is 7.5. This is more than twice the thermal efficiency of COP 3.5 of a typical geothermal heat pump.

As described so far, the thermomagnetic-type combined heating and cooling apparatus according to the present invention repeats the same operation cycle every 24 hours a day. After absorbing solar radiation into the greenhouse using cold water, only a portion of the absorbed heat is transferred from the cold water to the hot water through a heat pump. Both the cold and hot water are used for heating directly, and the heat loss on the surface of the greenhouse due to the late-night atmospheric temperature drop and the solar heat absorbed during the day are balanced. The next day, the cooled heat is used to cool and to absorb the heat needed for late night heating. In this case, the thermal efficiency (COP) can be increased up to 15 times or more.

In summary, the use of a heat pump that transfers heat from cold water to hot water is minimized, and both hot and cold water are used for heating in the late-night heating. This process supplies heating heat and reduces both the heat capacity of cold and hot water. To recover the cooling and heat absorption of the next cycle (next day).

In addition, the thermal efficiency (COP) of the thermal self-contained composite air conditioner according to the present invention is 15 in the winter season when the heating load is large, 8 in the late spring and early autumn when the heating load is reduced. This is very high compared to the efficiency 3.5 of geothermal devices recently developed for agriculture. The reason is that in the case of a heat pump, when heat is cooled, the heat must be discarded in the ground, and when heat or heat is required, all the necessary heat must be heat-exchanged with geothermal heat by using the heat pump at that moment. This is because the heat pump absorbs the heat absorbed during cooling and reuses it, and a large part of the heat absorbed by cold water is directly used for greenhouse heating without using a heat pump, and the load of the heat pump is reduced in the process.

In another aspect, the present invention is to effectively supply a dehumidification function that is one of the environmental factors required in the greenhouse of agricultural facility cultivation. The temperature of the refrigerant in the heat pump is so low that in the case of cooling using it, the temperature control is effective, but excessive dehumidification may adversely affect the plant. The average temperature of the cold water used in the cooling of the present invention is about 13 degrees, the dew point is relatively high, it is possible to control the appropriate humidity without a special control device.

In addition, the present invention provides a closed environment at the time when the day photosynthesis is most active, it is possible to enable a high concentration of carbonic acid fertilization in the greenhouse, this effect leads to the increase of cultivated crops and contributes to increased profitability.

In addition, the present invention can be very useful in the actual plant cultivation, in particular can be applied particularly effectively to winter fruits and vegetables that require dormant and cold elapsed time, such as strawberries.
