Description

Technology Field

[0001] The present invention relates to a monitoring and management system for a vertical mushroom cultivation facility (house) using eco-friendly energy such as solar and geothermal energy.

[0002] By cultivating mushrooms using unpolluted, eco-friendly energy, it becomes possible to grow mushrooms that are even more beneficial to human health.

[0003] More specifically, the present invention relates to a system for monitoring and managing the interior of a mushroom cultivation house using solar, geothermal, and groundwater heat sources to maintain the temperature, humidity, light intensity, and carbon dioxide concentration inside the mushroom cultivation house in an ideal state suitable for the mushroom growth environment.

[0004] Solar heat, geothermal heat, and groundwater heat are used as eco-friendly energy sources in the mushroom cultivation house monitoring management system of the present invention, thereby minimizing energy consumption. In addition, the heat pump cycle is controlled differently according to the temperature of the external environment and the actual conditions of the heat pump device to increase the efficiency of the heat pump cycle and prevent failure of the heat pump cycle in advance. In particular, the invention aims to prevent the death of mushrooms caused by freezing in winter while minimizing energy consumption. Background Technology

[0006] In the mushroom house environment control device for obtaining shiitake mushrooms and volcanic mushrooms according to the prior art document below (Patent Application No. 10-2017-0146050, Registration No. 10-1945872), a heat pump cycle is used to control and manage the environment, such as the temperature of the mushroom cultivation house, thereby controlling the temperature and humidity inside the mushroom house to provide an environment suitable for mushroom growth.

[0007] However, the above-mentioned conventional invention does not utilize eco-friendly energy such as solar or geothermal energy and uses a simple air source heat pump cycle, resulting in high energy consumption. In particular, when the heat pump cycle is continuously operated to maintain the internal temperature of a mushroom cultivation house at an appropriate temperature during the severe winter season, the refrigerant circulating through the internal refrigerant piping of the heat pump cycle must absorb heat from the severe outside air at the heat source-side heat exchanger. Consequently, the evaporation temperature of the refrigerant decreases, and the density of the refrigerant sucked into the compressor decreases.

[0008] If the refrigerant density drawn from the compressor decreases, the refrigerant flow rate of the refrigerant cycle decreases, making it difficult to secure heating capacity.

[0010] In addition, the conventional invention contains problems such as the decrease in the density of the refrigerant sucked into the compressor, which causes a small amount of refrigerant to be compressed and heated, resulting in an abnormally high temperature of the refrigerant discharged from the compressor, which leads to a decrease in the efficiency of the heat pump cycle, failure, or fire caused by overheating of the heat pump.

[0011] The present invention enables more economical mushroom cultivation by utilizing eco-friendly energy such as solar and geothermal energy. Prior art literature

[0017] We intend to install a sterilization light irradiation device inside the mushroom cultivation house to remove dust, bacteria, etc. from the air that has entered the cultivation house.

[0021] To this end, the present invention utilizes a heat pump cycle, changes the refrigerant flow path by automatic control of the heat pump cycle during the cold season, separately provides a heat exchanger to increase the efficiency of the heat pump cycle, and aims to efficiently manage a mushroom cultivation house while minimizing energy consumption by utilizing solar and geothermal energy.

[0022] In addition, the present invention aims to minimize energy consumption by directly introducing air from a groundwater well into the mushroom cultivation facility and utilizing it, and to enable the direct use of clean, uncontaminated air from the underground for mushroom cultivation.

[0024] Furthermore, the present invention aims to monitor the growth status of mushrooms in real time by installing an electrical conductivity meter and a camera in a mushroom cultivation box, and also to measure the environment inside the mushroom cultivation room in real time by installing various sensors inside the room, and to automatically control the system of the present invention by a controller based on the results.

[0139] Figure 1 is a configuration diagram of the vertical mushroom cultivation facility monitoring and management system using solar and geothermal energy according to the present invention. Specific details for implementing the invention

[0140] FIG. 1 illustrates a vertical mushroom cultivation facility monitoring and management system using solar and geothermal energy according to the present invention.

[0141] As illustrated in FIG. 1, the present invention comprises a vertical mushroom cultivation housing (30); and a heating and cooling water circulation pipe (30-CH) installed inside the vertical mushroom cultivation housing (30).

[0143] The above heating and cooling water circulation pipe (30-CH) can heat or cool the interior of the vertical mushroom cultivation housing (30) by circulating the heat medium stored inside the thermal storage tank (80).

[0144] A circulation pump (P) for circulating a heat medium is installed in the above heating and cooling water circulation pipe (30-CH), so that the heat medium stored inside the thermal storage tank (80) is sucked in from the inlet (30-CA) of the heating and cooling water circulation pipe (30-CH) and discharged through the outlet (30-CB) of the heating and cooling water circulation pipe (30-CH), thereby heating or cooling the interior of the vertical mushroom cultivation housing (30).

[0146] It was found through research that the internal temperature of the vertical mushroom cultivation housing (30) is 15°C to 23°C, which is suitable for mushroom cultivation, the relative humidity is 93% to 99%, the oxygen is 19% to 23%, and the carbon dioxide is 500 ppm to 800 ppm, which is suitable for the mushroom cultivation environment.

[0148] The heat medium stored in the above thermal storage tank (80) can receive thermal energy from the heat pump cycle (10), the solar water heater (40), and the groundwater well (50), respectively.

[0150] In addition, a supplementary water pipe (not shown) for the heat medium (WR) is installed in the above-mentioned thermal storage tank (80) to supplement the shortage of the heat medium (WR) inside the thermal storage tank (80).

[0153] A second heat medium circulation pipe (18) is installed between the second heat exchanger (17) and the heat storage tank (80), so that heat exchange between the second heat exchanger (17) and the heat storage tank (80) is possible.

[0155] A groundwater circulation pipe (51) is connected and installed between the groundwater well (50) and the thermal storage tank (80); the groundwater of the groundwater well (50) can be circulated into the groundwater circulation pipe (51) to exchange heat with the heat medium (WR) stored in the thermal storage tank (80).

[0157] The above-mentioned vertical mushroom cultivation housing (30) is formed with an external door (37) installed on the outer side of the vertical mushroom cultivation housing (30) and an internal entrance (36) through which a worker can pass through the external door (37) and enter the interior of the vertical mushroom cultivation housing (30), and an air curtain (36-AT) is installed above the internal entrance (36).

[0159] The operating principle of an air curtain is that a high-speed jet of air forms a wall. Air curtains are installed by using high-speed motors to drive tubes, centrifugal, or axial wind wheels to generate high-speed airflow, thereby forming a powerful airflow barrier.

[0161] The air curtain generates high-speed airflow, divides the first and second zones into two independent temperature zones to create a comfortable indoor environment, maintains indoor air conditioning and air purification effects, saves electricity, and circulates air to effectively isolate dust, smoke, and odor-causing microorganisms such as insects.

[0162] The continuously formed air vent effectively prevents the leakage of cold air, saves electricity, and can divide the first and second zones into two independent temperature zones. When the air conditioner operates for a long time, it can help circulate and regulate the temperature to save energy and improve the environment.

[0165] In addition, a temperature sensor (TS), a humidity sensor (HS), a gas concentration sensor (AS), and an illuminance sensor (RS) are installed inside the vertical mushroom cultivation housing (30); and a controller (CTU) is provided to control the vertical mushroom cultivation monitoring management system based on the measurements of the temperature sensor (TS), humidity sensor (HS), gas concentration sensor (AS), and illuminance sensor (RS).

[0168] Furthermore, the present invention enables the spraying of groundwater heated to a temperature suitable for the optimal growth of mushrooms onto the upper surface of a mushroom cultivation box. The specific spraying structure is as follows.

[0186] As described above, the heat medium (WR) inside the thermal storage tank (80) heated by solar heat is circulated through the cooling and heating water circulation pipe (30-CH) and can be directly used for heating the vertical mushroom cultivation housing (30), and

[0187] Since the energy of the heat medium (WR) inside the thermal storage tank (80) is used as a heat source for the heat pump cycle (10), heating and cooling of the vertical mushroom cultivation housing (30) can be achieved with minimal energy.

[0189] And, a light irradiation device (31) is installed inside the vertical mushroom cultivation housing (30); the light irradiation device (31) is composed of a growth light irradiation device (31-A) and a sterilization light irradiation device (31-B).

[0201] A database management system (DBMS) is provided to manage the information acquired by the above-mentioned electrical conductivity meter (33) and the information acquired by the camera (32) by combining and comparing them.

[0203] The above electrical conductivity meter (33) can monitor and manage the growth status of mushroom roots by installing a pair of spaced electrodes inside a mushroom cultivation box (34), measuring the change in capacitance between the electrodes, and transmitting the information in real time to a database management system (DBMS).

[0205] The above camera (32) is used to image mushrooms for monitoring mushroom growth, and to visualize the content of the mushroom's compositional material, it uses a multispectral camera that images with wavelengths ranging from visible light to near-infrared light.

[0212] And, during normal heating operation of the heat pump cycle (10) applied to the present invention, the circulation cycle (HC) of the refrigerant circulating along the inside of the refrigerant pipe (RPI) is;

[0213] High-temperature, high-pressure refrigerant discharged through the refrigerant piping (RPI-C) connected to the compressor (11) passes through the four-way valve (4-DV) and passes through the first heat exchanger (19) and the second heat exchanger (17) in sequence, where it is condensed and heat is released;

[0215] The refrigerant passing through the second heat exchanger (17) proceeds straight without branching at the first branch point (22), is depressurized and expanded by the first expander (15), and then flows into the third heat exchanger (13);

[0216] The low-pressure refrigerant introduced into the third heat exchanger (13) absorbs heat from the outside air as it evaporates.

[0218] The refrigerant that passes through the third heat exchanger (13) becomes a low-temperature, low-pressure gaseous refrigerant, passes through the four-way valve (4-DV), and flows into the gas-liquid separator (12), and the gaseous refrigerant separated in the gas-liquid separator (12) is then sucked into the compressor (11).

[0220] A first heat medium circulation pipe (20) is installed between the first heat exchanger (19) and the heat storage tank (80), so that heat exchange between the first heat exchanger (19) and the heat storage tank (80) is possible;

[0221] A second heat medium circulation pipe (18) is installed between the second heat exchanger (17) and the heat storage tank (80), so that heat exchange between the second heat exchanger (17) and the heat storage tank (80) is possible.

[0223] Meanwhile, during normal cooling operation of the heat pump cycle (10) applied to the present invention, the refrigerant circulation cycle (CC) is;

[0224] High-temperature, high-pressure refrigerant discharged through the refrigerant pipe (RPI-C) connected to the compressor (11) passes through the four-way valve (4-DV), condenses in the third heat exchanger (13), is depressurized and expanded by the first expander (15), and then evaporates while passing through the second heat exchanger (17) and the first heat exchanger (19) in sequence to absorb external heat.

[0225] The refrigerant that has passed through the first heat exchanger (19) becomes a low-temperature, low-pressure gaseous refrigerant, passes through the four-way valve (4-DV), and flows into the gas-liquid separator (12), and the gaseous refrigerant separated in the gas-liquid separator (12) is then sucked into the compressor (11).

[0227] A first heat medium circulation pipe (20) is installed between the first heat exchanger (19) and the heat storage tank (80), so that heat exchange between the first heat exchanger (19) and the heat storage tank (80) is possible;

[0228] A second heat medium circulation pipe (18) is installed between the second heat exchanger (17) and the heat storage tank (80), so that heat exchange between the second heat exchanger (17) and the heat storage tank (80) is possible.

[0231] And, during the emergency heating operation of the heat pump cycle (10) applied to the present invention, the circulation cycle (UC) of the refrigerant circulating along the inside of the refrigerant pipe (RPI) is;

[0233] High-temperature, high-pressure refrigerant discharged through the refrigerant piping (RPI-C) connected to the compressor (11) passes through the four-way valve (4-DV) and passes through the first heat exchanger (19) and the second heat exchanger (17) in sequence, where it is condensed and heat is released;

[0235] The refrigerant passing through the second heat exchanger (17) proceeds straight without branching at the first branch point (22), is depressurized and expanded by the first expander (15), and then flows into the third heat exchanger (13);

[0236] The low-pressure refrigerant introduced into the third heat exchanger (13) absorbs heat from the outside air as it evaporates.

[0238] The refrigerant that passes through the third heat exchanger (13) becomes a low-temperature, low-pressure gaseous refrigerant, passes through the four-way valve (4-DV), and flows into the gas-liquid separator (12), and the gaseous refrigerant separated in the gas-liquid separator (12) is then sucked into the compressor (11).

[0240] Meanwhile, the high-temperature, high-pressure refrigerant that has passed through the second heat exchanger (17) branches off at the first branch point (22), is depressurized and expanded by the second expansion unit (16), and then flows back into the second heat exchanger (17).

[0241] The low-pressure refrigerant introduced into the second heat exchanger (17) is heated by the high-pressure refrigerant passing through the second heat exchanger (17), then moves along the inside of the branch pipe (21), joins with the low-pressure refrigerant coming out of the third heat exchanger (13) at the refrigerant junction point (RP), and then enters the gas-liquid separator (12), and the gaseous refrigerant separated in the gas-liquid separator is sucked back into the compressor (11).

[0243] A first heat medium circulation pipe (20) is installed between the first heat exchanger (19) and the heat storage tank (80), so that heat exchange between the first heat exchanger (19) and the heat storage tank (80) is possible;

[0244] A second heat medium circulation pipe (18) is installed between the second heat exchanger (17) and the heat storage tank (80), so that heat exchange between the second heat exchanger (17) and the heat storage tank (80) is possible.

[0246] The emergency heating operation of the heat pump cycle (10) of the present invention is when the temperature measured by the outdoor temperature sensor (ATSN) installed in the heat pump cycle of the present invention is -6°C to -9°C or lower, or

[0247] When the temperature of the high-temperature, high-pressure refrigerant discharged through the refrigerant pipe (RPI-C) connected to the compressor (11) is detected and the temperature of the discharged refrigerant of the compressor is 110℃ to 130℃ or higher,

[0248] This can be implemented by controlling the controller (CTU) of the present invention.

[0250] And, depending on the change in the environment in which the present invention is applied and implemented, the heat pump cycle (10) of the present invention may be selected and operated in one of normal heating operation, emergency heating operation, and normal cooling operation by the operator implementing the present invention or the controller (CTU) of the present invention.

[0252] The heat pump cycle (10) applied in the present invention is intended to prevent the heating capacity of the first heat exchanger (19), which is responsible for the heat dissipation function during the heating cycle in the cold weather, from decreasing when the outdoor temperature is -6°C to -9°C or lower, as the pressure of the refrigerant sucked into the compressor (11) decreases and the amount of refrigerant circulation decreases.

[0254] In order to prevent a decrease in the heating capacity of the first heat exchanger (19), it is necessary to increase the enthalpy difference of the third heat exchanger (13), which functions as an evaporator during the heating cycle, by the supercooling of the refrigerant by the second heat exchanger (17), and to bypass the refrigerant to the branch pipe (21), thereby suppressing the amount of gaseous refrigerant with a small endothermic effect flowing in the low-pressure side of the heat pump cycle, so as to reduce the pressure loss in the low-pressure side of the heat pump cycle of the present invention.

[0256] When the pressure loss in the low-pressure side portion of the heat pump cycle of the present invention is reduced, the pressure of the refrigerant sucked into the compressor (11) increases and the specific volume decreases, so the amount of refrigerant circulation increases.

[0258] If the enthalpy difference of the third heat exchanger (13) which functions as an evaporator is increased, it may be possible to secure the amount of heat absorbed in the third heat exchanger (13) even if the mass flow rate of the refrigerant passing through the third heat exchanger (13) decreases due to the bypass of the refrigerant through the branch pipe (21).

[0259] In the heat pump cycle of the present invention, if the degree of subcooling and bypass amount of the refrigerant are maximized, the effect of improving the heating capacity of the first heat exchanger (19) which functions as a condenser during heating and the effect of significantly improving the coefficient of performance of the heat pump cycle can be obtained.

[0261] That is, when the outside temperature drops below a certain temperature, for example, when the outside temperature drops to -6°C to -9°C or lower, the efficiency of the heat pump cycle decreases rapidly. Therefore, the present invention aims to prevent the decrease in efficiency of the heat pump cycle and to prevent the following problems in advance by branching the refrigerant at the first branch point (22) as shown in FIG. 1 and supplying the refrigerant, which has exchanged heat with the second heat exchanger through the refrigerant branch pipe (21), to the compressor through the gas-liquid separator.

[0263] In cold weather conditions, the evaporation temperature in the heat pump cycle decreases, and along with it, the evaporation pressure decreases. Consequently, the density of the refrigerant drawn into the compressor becomes low, and the refrigerant flow rate decreases, resulting in insufficient cooling capacity of the evaporator. Furthermore, because the density of the refrigerant drawn into the compressor is low and the compression ratio becomes very high, the temperature of the discharged refrigerant rises excessively, causing problems such as damage to the compressor due to overheating.

[0265] In addition, a ventilation and supply port (30-VP) is installed in the vertical mushroom cultivation housing (30) of the present invention, and through the ventilation and supply port (30-VP), oxygen and carbon dioxide, etc. can be supplied into the interior of the vertical mushroom cultivation housing (30), and the air inside the vertical mushroom cultivation housing (30) can be ventilated.

[0266] Drawing symbol P, installed in the plurality of circulation pipes and the heating and cooling circulation water pipes (30-CH) of the present invention, is a circulation pump that circulates a heat medium or groundwater filled inside the circulation pipes. The heat medium (WR) stored inside the thermal storage tank (80) can be water.

[0268] In the present invention, a plurality of heat medium circulation pumps (P) or groundwater circulation pumps (P) can be operated (on) or stopped (off) by the control of a controller (CTU).

[0269] Accordingly, when cooling of the vertical mushroom cultivation housing (30) is required, such as during the summer when the outside temperature is above a certain temperature, the circulation pumps that do not need to be operated, including the heat medium circulation pump (P) of the heat medium circulation pipe (41) installed between the solar water heater (40) and the thermal storage tank (80), can be stopped.

[0270] In addition, although not shown in the drawings of the present invention, various sensors such as a temperature sensor for measuring temperature (such as an ambient temperature sensor), a humidity sensor, and a light sensor may be installed in addition to the components of the present invention, such as the thermal storage tank (80) and the groundwater well (50), for the control of the controller (CTU).
