Description

A mushroom cultivation apparatus

The present invention relates to a mushroom cultivation apparatus, and more particularly, to a mushroom cultivation apparatus capable of flexibly responding to changes in temperature, humidity, and carbon dioxide concentration so that cultivation of mushroom sensitive to the outside environment can be performed more efficiently.

Ventilation is important when growing mushrooms because the amount of carbon dioxide (CO2) in the mushroom cultivation room greatly affects mushroom growth.

 The ventilation work of a general mushroom cultivation room is performed by repeating the operation and the stop of the ventilation fan in the mushroom cultivation room at regular time intervals.

In addition, since the temperature and humidity inside the mushroom cultivation room are also important for mushroom cultivation, the case where the air conditioner is installed inside the mushroom cultivation room is increasing, but the inside of the mushroom cultivation room can be efficiently ventilated, Specialized

Air conditioning facilities have not been proposed yet, and air conditioning facilities capable of efficiently managing carbon dioxide have not been proposed.

On the other hand, conventional mushroom cultivation apparatuses such as the Korean utility model registration 20-0207824 have a problem that low-temperature dehumidification is difficult, so that the production of high-quality mushrooms (for example, white flags) can only be performed in low-temperature seasons. , There is a problem that it is difficult to control them integrally because of various components, and temperature control is difficult.

It is an object of the present invention to provide an all-in-one mushroom cultivation apparatus capable of growing mushrooms at any time and providing user convenience in order to solve such problems.

It is another object of the present invention to provide a mushroom cultivation apparatus capable of minimizing indoor heat loss while performing ventilation, and capable of performing dehumidification or cooling operation more flexibly.

In order to accomplish the above object, the present invention provides a mushroom cultivation space supply system, And a constant temperature and humidity module that is connected to the supply duct and adjusts a temperature of air flowing into the supply duct, wherein the constant temperature and humidity module includes a plurality of And a heating device provided between the evaporator and the plurality of evaporators.

The first expansion valve for low temperature and the first expansion valve for room temperature are separately arranged in the refrigerant pipe connected to the first evaporator and the second expansion valve is installed in the pipe connected to the second evaporator .

The heating device is composed of a heater, wherein the plurality of evaporators includes a first evaporator disposed adjacent to the inlet of the thermo-hygrostat, and a second evaporator disposed adjacent to the outlet of the thermo-hygrostat, 2 evaporator.

Wherein the heating device comprises a heated condenser, wherein the plurality of evaporators comprises a first evaporator disposed adjacent the inlet of the thermo-hygrostat, and a second evaporator disposed adjacent the outlet of the thermo-hygrostat, And a heat condenser is disposed between the evaporators.

The heating condenser is characterized in that a part of the refrigerant pipe connected to the discharge region of the compressor is connected to a branched branch pipe.

The pipe connected to the discharge portion of the heated condenser is connected to a pipe connected to either the condenser or the plurality of evaporators, so that the refrigerant recovered in the heated condenser is guided to the evaporator.

According to the present invention, the mushroom cultivation device is provided by the all-in-one method, so that more convenient installation and management is possible.

On the other hand, carbon dioxide concentration control, temperature control, and humidity control can be performed easily.

In particular, since the high temperature and high humidity operation or the low temperature and low humidity operation can be performed periodically according to the daytime and night time zones, the growth environment of the quality mushroom can be adjusted.

In the case of the thermo-hygrostat, a plurality of evaporators and a plurality of compressors can be used to selectively implement a single cycle or a dual cycle.

On the other hand, since the heat condensation heater and the heater are used in the thermo-hygrostat, if the dehumidification is not performed at a low temperature, the dehumidification can be performed by raising the temperature.

It is advantageous to minimize heat loss by introducing outside air and exhausting air through the total heat exchanger. When the introduced outside air is not directly directed to the mushroom cultivation space providing part, it enters through the thermo-hygrostat, Can be prevented.

In addition, the guide duct inside the mushroom cultivation space becomes narrower as it moves toward the air moving direction, so that even air can be exhausted from the entire area.

The loading shelf 102 has a multi-layered structure, in which a medium can be placed in the space, and the mushroom can be cultivated.

Meanwhile, a corridor 101 is provided between the loading shelf 102 and the loading shelf 102 so that the user can pass it.

A communication duct (42) communicating with the thermo-hygrostat (20) is provided at a lower portion of one side of the mushroom cultivation space providing unit (10).

The communication duct 42 is connected to the inlet of the thermo-hygrostat 20 to guide the air inside the mushroom cultivation space providing chamber 10 to the entrance of the thermo-hygrostat 20.

A supply duct 110 is provided above the inner space of the mushroom cultivation space providing unit 10.

The supply duct 110 is arranged along the inner space ceiling of the mushroom growing space providing unit 10 and is provided outside the mushroom growing room providing unit 10 and has a connecting duct 41 connected to the discharging unit of the thermo-hygrostat 20 .

The width of the second supply duct 112 is preferably constant.

The reason why the width becomes narrower toward the direction of air progression is that when the air enters the supply duct 110 for the first time, since the pressure is intense, the pressure is dispersed to disperse the pressure at the beginning portion, It is weakened so that the width is narrowed to increase the speed so that the air can move to the end.

In this figure, the first supply duct 111 and the third supply duct 113 are shown to be narrowed in three stages, but the present invention is not limited thereto, and may be implemented in two stages or three stages or more .

The discharge port 114 is disposed on the lower surface of the supply duct 110 and is disposed to face the bottom of the mushroom growing space providing unit 10.

The discharge ports 114 are arranged to be spaced apart from each other along the supply duct 110.

(Two in this figure) of compressors 211 (211a, 211b) and a plurality (two in this figure) of compressors 211 are provided in the housing 201 of the thermo-hygrostat 20 as shown in Figs. 8 to 10, 212a and 212b and a plurality of condensing fans (two in this figure) 213, 213a and 213b are provided.

The compressor 211, the condenser 212 and the condensing fan 213 are arranged in the first area (outdoor unit area) of the thermostatic / hygroscopic device 20 (201).

The compressor 211 is preferably a scroll compressor, but is not limited thereto.

On the other hand, the temperature and humidity module 250 and the air blowing fan unit 220 are disposed in the second area (indoor unit area) of the thermo-hygrostat 20 housing 201.

The blowing fan unit 220 is disposed at an upper portion of the second region of the thermo-hygrostat housing 201.

10 (a) is a schematic view of the inside of the constant temperature / constant humidity module 250, and FIG. 10 (b) is an external perspective view of the constant temperature and constant humidity module 250. FIG.

The constant temperature / constant humidity module 250 includes a metal frame 251.

A plurality of evaporators 252 are provided in the frame 251, and the evaporators 252 are spaced apart from each other.

In this embodiment, the first evaporator 252a and the second evaporator 252b are distinguished for convenience, but the number is not limited thereto.

A defrost heater 253 is provided in front of the first evaporator 252a.

The defrost heater 253 is connected to the frame 251 to defrost the first evaporator 252a and the second evaporator 252b by conduction of the frame 251 when the defrost heater 253 generates heat .

The defrost heater 253 is provided in the form of a coil and generates heat by resistance when a current is applied thereto. However, the defrost heater 253 is not limited to this but may be any configuration for generating heat.

A heating device for temperature compensation is provided between the first evaporator 252a and the second evaporator 252b.

In Fig. 11A, a heating condenser 254 is provided as a heating device. In the case of the heated condenser 254, it is provided to raise the temperature of the air that has passed through the first evaporator 252a, the operation of the heated condenser being optional.

The first-order temperature compensation is performed by the operation of the heated condenser 254.

For example, when the temperature of the air passing through the first evaporator 252a is 0 ° C or less, hot refrigerant may flow into the heating condenser 254 to increase the temperature of the air.

When the air temperature is low during the dehumidification operation, dehumidification by the evaporator is not smooth, so it is also necessary to raise the air temperature.

In the case of the second evaporator 252b, it is installed in the discharge portion of the heating condenser 254.

The first evaporator 252a and the second evaporator 252b are independent from each other.

Therefore, when the required cooling capacity is normal, the first compressor 211a is operated so that the refrigerant flows into the first evaporator 252a (single cycle), and when a large amount of cooling capacity is required, the second evaporator 252b and the second evaporator 252b Both the first and second compressors 211a and 211b are operated so that the refrigerant flows into the first evaporator 252a (dual cycle).

It is preferable that the defrost heater 253, the first and second evaporators 252a and 252b, and the heating condenser 254 are integrally formed in the frame 251.

A humidifier 255 for humidifying air is provided on the discharge side of the frame 251. The humidifier 255 is provided by a vaporization type humidifier.

That is, when a part of the filter through which the air passes is put into a container for holding water, the capillary phenomenon absorbs the water into the filter, and the air is sucked into the filter through the wet filter.

Then, the principle is used that only pure water is evaporated from the filter to humidify the air.

A heater 256 is provided on the discharge side of the humidifier 255. The heater 256 is preferably a heating coil.

The heating heater 256 is provided for secondary temperature compensation.

That is, if the temperature of the air is lower than the reference temperature by the primary temperature compensation, the heating heater 256 is used to further increase the temperature.

11A, the compressor 211 includes a first compressor 211a and a second compressor 211b, and the condenser 212 also includes a first condenser 212a and a second condenser 212b.

The refrigerant pipe connected to the discharge side of the second compressor 211b is connected to the second condenser 212b.

A branch pipe 218 is provided in the refrigerant pipe connected to the discharge side of the second compressor 211b. The branch pipe 218 guides the refrigerant at a high temperature to the heating condenser 254.

The branch piping 218 is provided with a control valve 218a for controlling the flow of the refrigerant and guides or blocks the refrigerant to the heat condenser 254 according to the control operation of the control unit.

On the other hand, a second expansion valve 262 is provided in the refrigerant pipe connecting between the second condenser 212b and the second evaporator 252b to expand the refrigerant under pressure adiabatically.

The refrigerant pipe 219 connected to the discharge side of the heating condenser 254 is connected to the refrigerant pipe provided between the second condenser 212b and the second evaporator 252b and connected to the refrigerant pipe connected to the front side of the second expansion valve 262 do.

Therefore, the refrigerant that has passed through the heating condenser 254 can be moved to the second expansion valve 262 and expanded under reduced pressure.

The first compressor 211a is connected to the first condenser 212a and the first condenser 212a is connected to the first evaporator 252a through a refrigerant pipe.

The refrigerant pipe connecting the first evaporator 252a and the first condenser 212a is provided with two expansion valves 261a and 261b, one of which is a low-temperature first expansion valve 261a, Constitutes a first expansion valve 261b for room temperature.

It is preferable that the low temperature range is within a range of about 7 ° C (for example, 6 to 8 ° C), and the room temperature range is preferably within about 13 ° C (12 to 14 ° C) It can be different.

It is necessary to control the temperature and the room temperature in consideration of the nighttime and daytime temperature variations in the optimal culture condition of nature.

Therefore, it is preferable to adjust the temperature in accordance with the change of the night time zone and the daytime time, and further adjust the humidity accordingly.

In order to provide air at room temperature, the low-temperature first expansion valve 261a is closed and only the room-temperature first expansion valve 261b is opened so that the refrigerant is supplied only through the room-temperature first expansion valve 261b, .

In order to provide low-temperature air, the low-temperature first expansion valve 261a is also opened to allow the refrigerant to be supplied through the first expansion valve 261a as well as the room-temperature first expansion valve 261b , So that the decompression expansion process is performed in both of the expansion valves.

When a lower temperature is required in this state, the second compressor 211b is driven while the second expansion valve 262 is driven so that the refrigerant is also supplied to the second evaporator 252b.

11B shows a heater 254a that heats the air by receiving electrical energy instead of the heating condenser 254 as a heating device.

The role of the heater 254b in Fig. 11B is the same as that of the heated condenser 254. Therefore, except for the heater 254a in place of the heating condenser 254, the remaining components are the same, so that the description of the same components will be omitted for the sake of avoiding redundant explanations.

However, the necessity of the honeycomb hygroscopter for mushroom cultivation shown in Figs. 11A and 11B is as follows.

In the case of constant temperature and humidity air conditioners for mushroom cultivation, the temperature should be used at low temperature and low humidity, low temperature and high humidity of 5 ℃, 50 ~ 90%, 13 ℃, 50 ~ 90%

Since 1.8 kg of 3 kg of mushroom medium is composed of water and there are more than 2,000 on average in the cultivation room, it is inappropriate to take the normal room temperature thermo-hygrostat for proper low temperature dehumidification.

If the temperature is lowered to a room temperature condition (18 to 23 degrees) in a hot temperature condition (eg, 30 degrees) formed by the respiration of the mushroom, and the humidity is to be dehumidified (for example, 90 to 60% It can be sufficiently achieved as a hygrostat (an evaporator is provided at the inlet side and a reheat condenser is disposed at the outlet side).

In this case, there is no fear that the condensed water dehumidified on the surface of the evaporator is frozen.

However, in order to perform dehumidification while lowering the temperature in a hot temperature condition (for example, 30 degrees) to a low temperature condition (5 to 13 degrees), it is necessary to consume a considerable amount of energy as compared with the above- It is impossible to dehumidify only with the evaporator in front of the reheat condenser.

In the case of dehumidification, the heat transfer area is an important factor. In the case of the thermo-hygrostat provided at one side of the mushroom cultivation space as in the present invention, there is a limit to increase the area in terms of productivity and space utilization.

Therefore, in order to perform the dehumidification efficiently, the primary evaporator and the secondary evaporator are respectively disposed.

That is, it is necessary to configure the evaporator in series (primary evaporator-secondary evaporator) in the constant-temperature and air-humidity case.

The characteristics of the air temperature control and the humidity control show that the descending speed of the temperature is significantly faster than the descending speed of the humidity.

Therefore, even if the temperature reaches the desired temperature, the humidity often falls short of the target, and when the humidity reaches the target, the temperature may excessively fall.

Therefore, it is necessary to compensate by increasing the temperature without affecting the humidity by the reheat condenser.

For example, assuming that the final air temperature / humidity target is 5 ° C and 60%, the first evaporator and the second evaporator are in series, and in the absence of a reheat condenser, , But the humidity can not reach 60%.

When passing through the secondary evaporator in this state, the humidity can reach 60%, but the temperature of the air drops to -2 to 3 degrees, which causes the condensation water in the secondary evaporator to freeze.

Therefore, it is necessary to place a heating device such as a heater or a heat condenser in the primary evaporator and the secondary evaporator so as not to affect the humidity while raising the temperature of the air passing through the primary evaporator.

Therefore, by controlling the dew point of the air flowing into the secondary evaporator, it is possible to maintain the temperature of the low temperature and low humidity (5 ° C 60%) indoors.

However, in a constant temperature air conditioner used at room temperature, only the evaporator-condenser is used. In the case of performing dehumidification and cooling, the temperature does not drop to the desired humidity even if the desired temperature is reached.

In order to prevent such incomplete dehumidification, an evaporator is added after a heating device (a heating condenser, a heater), and a heating device (a heating condenser, a condenser, and a condenser) is installed in order to prevent the temperature of the air from being excessively lowered by the added secondary evaporator. Heater) is operated to increase the temperature of the air before entering the second evaporator.

If the refrigerant is supplied to the evaporator as much as possible and the humidity is adjusted to a desired level, the temperature will be lower than the target point, and the air temperature will be below minus zero and the condensation of the evaporator will freeze Lt; / RTI >

 Therefore, it is impossible to dehumidify at low temperatures due to the structure of the evaporator-condenser such as the constant temperature and humidity machine used at normal room temperature.

Meanwhile, in the present invention, the first room temperature expansion valve and the first low temperature expansion valve are connected to the first evaporator.

Further, in the case of the first evaporator of the present invention, the refrigerant having passed through the first room temperature expansion valve can flow into one coil, and the refrigerant having passed through the first low temperature expansion valve can pass through. Therefore, the cooling capability can be controlled for one coil.

Further, in the present invention, the refrigerant having passed through the first room temperature expansion valve is used for one coil of the first evaporator, or the refrigerant having passed through the first low temperature expansion valve is used. Therefore, There is no.

In the case of the present invention, since all of the air passes through both the first evaporator and the second evaporator, and the refrigerant flows through both of the first and second evaporators, the possibility of air escaping into the region where the refrigerant does not flow is blocked.

12 is a schematic view of the total enthalpy heat exchanger (30) and the constant temperature / constant humidity module (200).

The total enthalpy heat exchanger (30) is provided for introducing outside air for ventilation when the concentration of carbon dioxide in the mushroom growing space providing unit (10) becomes a certain level or more.

The outside air is heat-exchanged with the inside air discharged to the outside so that the temperature of the air inside the mushroom cultivation space 10 is not changed abruptly.

In the present invention, it is desirable that the concentration of carbon dioxide can be maintained within the range of 1,000 to 2,500 ppm, but the range may vary depending on the environment and the circumstances.

The total enthalpy heat exchanger 30 includes a housing 301 and a heat exchange module 302 provided inside the housing 301. The housing 301 is provided with an outside air inlet 311 and an outside air outlet 312 and an inside air inlet 313 And an exhaust outlet 314 are provided.

The air introduced by the outside air inlet port 311 is represented by OA (Outside Air), and the air which is discharged by the outside air outlet port 312 and supplied to the temperature and humidity module 200 is indicated by SA (Supplied Air).

The air introduced by the air inlet 313 is indicated by RA (Returned Air), and the air exhausted by the air outlet 314 is indicated by EA (Exhausted Air).

When the carbon dioxide concentration measured by the carbon dioxide concentration sensor 153 becomes equal to or higher than a certain level, the control unit 400 opens the shutter of each inlet / outlet.

In this state, the outside air moves along the OA - > SA path and passes through the heat exchange module 302 in the meantime.

The vest of the mushroom cultivation space supply 10 moves along the RA-> EA path and passes through the heat exchange module 302 in the meantime.

In the heat exchange module (302), the outside air flow path and the inside air flow path are arranged so as to intersect with each other.

Therefore, the outdoor air moving along the outdoor air flow path and the indoor air moving along the indoor air flow path perform heat exchange without being mixed with each other.

Therefore, the outside air is cooled by the inside air.

The cooled outside air flows into the guide passage 42 provided between the constant temperature and humidity module 200 and the mushroom holding space providing portion 10 and the outside air flowing into the guide passage 42 is heated by the constant temperature and humidity module 200 And further humidified and introduced into the mushroom cultivation space providing chamber 10.

That is, most of the air circulates through the mushroom growing space providing unit 10 and the temperature and humidity module 200, and some air is newly supplied by the total enthalpy heat exchanger 30 and mixed with the circulating air.

By this process, fresh outside air can be introduced into the mushroom growing space providing chamber 10, and the carbon dioxide concentration can be lowered as carbon dioxide exits to the outside.

Hereinafter, the main control operation of the present invention will be described.

It is determined whether the current time zone is the weekly time zone (for example, 06: 00-18: 00) or the night time zone (18: 00 ~ 06: 00) (S1601).

During the day, it is necessary to operate at high temperature and high humidity.

Therefore, water is further supplied to the humidifier to achieve high-humidity operation (for example, humidity 70 to 90%) (S1602).

Then, the first compressor is operated so as to be in a normal temperature state (e.g., 13 DEG C), and the first expansion valve for normal temperature is operated (S1603). However, if the internal temperature rises due to the inflow of outside air or the rise of the external temperature, the first expansion valve for low temperature may be additionally operated (S1604).

Meanwhile, the low temperature and low humidity operation is performed in the night time zone (S1605). Here, the low humidity can be 50 to 70% of the humidity, for example.

The first compressor and the second compressor are operated so as to be in a low temperature state (e.g., 7 DEG C) (S1606), and the first expansion valve for room temperature, the first expansion valve for low temperature, and the second expansion valve are operated (S1607 , S1608).

Then, the first compressor or the second compressor can be controlled while the set temperature range is checked, or the expansion valve can be controlled.

Fig. 17 shows a control method of controlling the humidity.

It is determined whether the current humidity belongs to the reference humidity range (e.g., 70 to 80%) (S1701).

As a result of the determination, if it is determined that the humidity is excessive and dehumidification is necessary, first, the temperature of the air discharged from the thermo-hygrostat is checked and it is determined whether or not it is lower than the reference temperature (for example, 0C) (S1702).

If the temperature is too low, dehumidification will not occur.

Therefore, when the air discharge temperature is equal to or lower than the reference temperature, the control valve in the branch pipe is operated so that the refrigerant flows into the heating condenser (S1703).

If the temperature is above the reference temperature, operation of the heating condenser is not required.

Then, the first compressor is operated and the room temperature first expansion valve is operated to perform the defrosting operation in the first evaporator (S1704, S1705). Optionally, however, the second expansion valve may be operated in addition to the low-temperature expansion valve, and further the second compressor and the second expansion valve may be operated so as to be dehumidified in the second evaporator.

On the other hand, if it is determined that humidification is necessary due to the lack of humidity, the humidifier is replenished with water (S1706), and the RPM of the blower fan is dropped to reduce the flow rate of air passing through the filter of the humidifier, (S1707).

On the other hand, when the humidifying operation is selectively performed, the operation of the compressor can be temporarily stopped. This is to prevent dehumidification by the evaporator from occurring when the temperature condition falls within the reference range.

18, it is determined whether or not the carbon dioxide in the mushroom growing space supply exceeds the predetermined reference range (e.g., 1000 to 2500 ppm) (S1801). If the amount of carbon dioxide exceeds the predetermined reference range (S1802). In this case, ambient air flows into the thermo-hygrostat.

At the same time, the mushroom cultivation space supply air is discharged to the outside through the total heat exchanger

At this time, the heat exchange module performs heat exchange between the inside air and the outside air, thereby minimizing heat loss.

As the outside air is introduced, the concentration of carbon dioxide inside the mushroom cultivation space is gradually lowered. In this case, it is determined whether or not the concentration of carbon dioxide is below the reference range (S1803). In such a case, the indoor heat exchanger is turned off to stop the inflow of the outside air, and the air is cooled and circulated between the thermostat and the mushroom growing room S1804).

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be appreciated that one embodiment is possible.

Accordingly, the true scope of the present invention should be determined by the technical idea of the claims.
