The above-mentioned digital cooling control system of the present invention is based on the following studies.

1. 1. Refrigerating / freezing cooling function cycle 1-1
There are evaporation temperature and condensation temperature as the standard of set temperature of refrigerated / frozen products, and the condensation temperature is the temperature when the refrigerant gas is compressed and liquefied. For example, when the refrigerant gas is compressed by the compressor, the refrigerant Depending on the type and evaporation temperature, the discharge temperature will be around 100 ° C, for example. In the case of air cooling, the high temperature state of the refrigerant gas at 100 ° C will be cooled by the plate fin type heat exchanger of the condenser, and the suction surface will be cooled. The wind speed is usually 2 m / sec, the condensation temperature is around 55 ° C in the case of 32 ° C in summer, and the cooling capacity for refrigeration / freezing is (100 ° C-55 ° C) = 45 ° C. The numerical cooling capacity becomes the capacity of each refrigerator, and the power required for compression increases or decreases.

1-2
Therefore, a decrease in the outside air temperature in the summer or a decrease in the outside air temperature in the normal season affects the capacity of the refrigerator and the increase / decrease in the load, and the power consumption increases or decreases.

1-3
When the refrigerating / freezing case and the refrigerating / freezer case / inside temperature are, for example, ice-26 ° C and cold food -18 ° C, the evaporation temperature is set to -40 ° C as the standard cooling capacity of the refrigerator. When the internal temperature is, for example, 0 ° C for meat / fresh fish, 3 to 5 ° C for daily delivery / prepared food, and 7 ° C for fruits and vegetables, the evaporation temperature can be set to the cooling capacity of the refrigerator based on −10 ° C.

2. 2. Refrigerator characteristics for refrigeration / freezing applications 2-1 Each process of refrigeration cycle Refrigeration cycle is as follows.
(1) Compression step (compressor): The low-pressure refrigerant evaporated by the evaporator is sucked by compression and the high-pressure refrigerant is discharged. (Low pressure → High pressure: Adiabatic compression)
(2) Condensing step (condenser): The high-pressure and high-temperature refrigerant from the compressor is cooled and liquefied by the condenser. In addition, air and cooling water are used as the cooling medium. (Constant pressure change: constant pressure compression)
(3) Expansion step (expansion valve): The refrigerant liquefied by the condenser is cooled at low pressure by the expansion valve and discharged to the evaporator. (High pressure → low pressure: throttle expansion)
(4) Evaporation step (evaporator): The refrigerant cooled at low pressure by the expansion valve is evaporated by the evaporator to cool the air and other objects. (Constant pressure change: low pressure expansion).

2-2 Coefficient of performance of refrigeration cycle
The main factors that affect the coefficient of performance COP (cooling heat quantity / compression power) are evaporation temperature and condensation temperature.
Evaporation temperature: The higher the evaporation temperature, the larger the refrigerating capacity and the smaller the compression power. Condensation temperature: The lower the condensation temperature, the larger the refrigerating capacity and the smaller the compression power.

2-3 Evaporation temperature
Since the evaporation temperature is set to an appropriate value for the object to be cooled, it is a constant value except in the case of an excessive increase in the refrigerating load or equipment failure.

2-4 Condensation temperature
The condensation temperature changes depending on the size of the refrigerating load and the state of the cooling medium such as air in the condenser. For this reason, the refrigerating capacity and compression power are strongly affected by the condensation temperature, so suppressing the condensation temperature is extremely important for energy-saving operation.

3. 3.
<Lower condensation temperature when using a sprinkler cooling mat>
The inventor of the present application examined the efficiency of lowering the condensation temperature in a compressor (condenser) by flowing water down the sprinkler cooling mat 13 described in the embodiment described later.

Even when the blower fan 12 described in the embodiment described later is not operated, the outside air sucked into the air suction portion of the outdoor unit passes through the sprinkler cooling mat 13 to which the moisture is flowing, and is generated by the heat of vaporization. , It becomes an air flow whose temperature is lower than that of the outside air and is sucked into the air suction part of the outdoor unit. As a result, the condensation temperature can be lowered as compared with the case of a conventional air-cooled condenser that does not use the sprinkler cooling mat 13.

When the heat transfer rate was calculated and then examined by the present inventor with reference to the heat transfer temperature difference and the suction air temperature, the use of the sprinkler cooling mat 13 was used when the outside air temperature was, for example, 32 ° C. Compared with the case of the conventional air-cooled condenser which does not carry out, the condensation temperature is lowered from about 3 ° C. to 5 ° C. from 29 ° C. to 27 ° C. The flow velocity of the air flow sucked into the air suction part of the outdoor unit was examined as 2.0 m / sec.

<Lower condensation temperature when using a blower fan and sprinkler cooling mat>
The inventor of the present application operates the blower fan 12 described in the embodiment described later, and the air flow generated by the blower fan 12 passes through the sprinkler cooling mat 13 on which water is flowing down to cause a compressor (condenser). The efficiency with which the condensation temperature was lowered was examined.

The air flow that is forcibly flowing toward the air suction part of the outdoor unit by the operation of the blower fan 12 passes through the sprinkler cooling mat 13 where the moisture is flowing down, and the temperature rises higher than the outside air due to the heat of vaporization. It is sucked into the air suction part of the outdoor unit at a wind speed that is lowered and strengthened by the blower fan 12. As a result, the condensation temperature can be lowered.

The heat transfer rate was calculated, and then the inventor of the present application examined it with reference to the heat transfer temperature difference and the suction air temperature. When the outside air temperature was, for example, 32 ° C., the blower fan 12 and sprinkling cooling were performed. Compared with the case of the conventional air-cooled condenser without using the mat 13, the condensation temperature is lowered by 9.4 ° C. This is because the heat transfer temperature required for heat exchange becomes smaller due to the temperature decrease due to the heat of vaporization and the improvement of the heat transfer coefficient. The flow velocity of the air flow sucked into the air suction part of the outdoor unit by the operation of the blower fan 12 was examined as 4.0 m / sec.

<Energy saving effect of freezing machine power by lowering the condensation temperature>
As a result of examination by the inventor, the use of the sprinkler cooling mat 13 by causing water to flow down to the sprinkler cooling mat 13 by using only the sprinkler cooling mat 13 without operating the blower fan 12 described in the embodiment described later. Compared with the case of the conventional air-cooled condenser that does not perform the above, the energy saving effect of the refrigerating machine power is that when the condensation temperature drop is, for example, 55 ° C → 50 ° C, the evaporation temperature is set for each type of refrigerant, for example. When set as follows, it was as shown in Table 1 below.

Further, as a result of examination by the inventor, the refrigerating operation is compared with the case of a conventional cold condenser using the blower fan 12 and the sprinkler cooling mat 13 described in the embodiment described later and not using any of them. The power saving effect was as shown in Table 2 below when the condensation temperature drop was set to, for example, 55 ° C → 45 ° C, and the evaporation temperature was set for each type of refrigerant as follows, for example. ..

In the studies of Tables 1 and 2 above, the energy saving effect of the refrigerating mobility due to the decrease in the condensation temperature was calculated by the ratio enthalpy difference between the discharge process and the evaporation process based on each specific enthalpy value of the refrigeration cycle according to the hp diagram. The conditions for calculating the specific enthalpy are as follows.
(1) Superheat degree (SH) of sucked vapor: 0 [° C.]
(2) Supercooling degree of condensate (SC): 0 [° C]
(3) The specific enthalpy after the compressor is discharged is calculated from the theoretical compression value and compression efficiency.

Based on the above examination results, the digital cooling control system of the present invention is as follows.

3-1
The cooling capacity of the condenser (condenser) increases, the condensing capacity of the condenser (condenser) increases, and the operating coefficient of the refrigerator decreases.

1) For example, the energy saving effect in the case of only sprinkling water on the sprinkler cooling mat is as follows.
When the evaporation temperature is -10 ° C (meat / fresh fish, daily delivery / prepared food, fruits and vegetables, etc.): 14.8% to 20.9%
When the evaporation temperature is -40 ° C (ice, cold food, etc.): 11.4% to 20.2%

2) For example, the energy saving effect when watering the watering cooling mat and the blower fan are combined is as follows.
When the evaporation temperature is -10 ° C (meat / fresh fish, daily delivery / prepared food, fruits and vegetables, etc.): 28.1% to 37.4%
When the evaporation temperature is -40 ° C (ice, cold food, etc.): 21.5% to 35.2%

3-2
For example, the following controls can be selected for the operation of the blower fan and the sprinkling of water on the sprinkler cooling mat.
1) Control at maximum temperature 2) Stop operation with rain sensor

3-3
The refrigerator operating coefficient can be handled as follows, for example.
1) Calculation of the chiller operating coefficient based on the pulse signal input of the chiller power amount 2) The chiller operating coefficient is an arbitrarily set number, and can be, for example, 30 to 40% or more.

3-4
The temperature in the atmosphere, for example, 30 ° C., is lowered by about 3 to 5 ° C. or 4 ° C. to 6 ° C. by the air blown by the blower fan and the heat of vaporization by the sprinkling cooling mat.

4-1
Due to global warming, for example, not only from April to October but also from November to December, January to March, etc., the rise in outside air temperature occurs throughout the four seasons of the year. For this reason, the operating coefficients of refrigerating / freezing showcases, refrigerating / freezer, etc. and air conditioners increase throughout the four seasons, and power consumption increases. When the operating coefficient of the equipment reaches a predetermined value of, for example, 30% to 40% due to an increase in the outside air temperature, the air-cooled condenser is operated by operating the blower fan and watering the watering cooling mat. In order to enhance the cooling function of the fins of the system, a water supply gate is installed at the bottom of the piping of the system, and the pulse signal of the outside air temperature sensor or the equipment that detects the operating coefficient is input, and the set temperature, for example, 24 ° C or operating. When the coefficient reaches, for example, 30 to 40%, the water supply gate valve of the pipe is opened by the electromagnetic valve and watering is started.

4-2
Notwithstanding the above, for example, if the outside air temperature from December to March is 20 ° C. or less, or the operating coefficient is, for example, 20%, which is an arbitrarily set number of days, for example, if it reaches up to one week. A signal is sent to the solenoid valve, the water supply gate closes, the water in the pipe is automatically stopped, and the accumulated water in the pipe in winter is automatically drained when the drainage solenoid valve of the pipe opens. Prevents destruction due to freezing.

4-3
It is also possible to stop the water supply when the temperature difference between the water supply for watering and the outside air temperature is, for example, 1 to 2 ° C., due to the direct sunlight of the outside air or the high temperature of the outside air.

4-4
The system is a system that enhances the fin cooling function of the air-cooled condenser (condenser), enhances the condenser (condenser) intake function of the heat of water vaporization, and lowers the operating coefficient of the refrigerator. In that case, the sprinkler air filter If silica or the like contained in the water sprinkling adheres to the water, the intake cooling capacity of the condenser will be significantly reduced.

4-5
For example, silica or the like that has adhered to the above sprinkling cooling mat over a period of 1 to 3 years is fixed, which takes a long time when the system removes the fixing bolts or binding fittings and slides the sprinkling cooling mat laterally. At present, the work time and contents for sliding the sprinkler mat can be easily removed and attached with one touch, and anyone can easily do it.

4-6
The system can be air-cooled, refrigerated / frozen showcase, and air-cooled refrigerated / freezer. The current value and power value of the outdoor condenser (condenser) and cooling device are input as pulse signals, and the outside air temperature and rain sensor are used. Will be installed around the equipment.

4-7
An anemometer is attached to the inside of the sprinkler cooling mat (on the air suction port side of the outdoor unit), and the air velocity is an indicator that the gap through which the air blows has narrowed due to the adhesion of silica or the like to the sprinkler cooling mat. Know in advance the relationship with the wind speed measured by the meter. For example, when the blower fan is being driven at the set wind speed, if the wind speed detected by the anemometer drops to a wind speed corresponding to a space ratio of 60 to 70%, the state of the sprinkler mat is changed. It is transmitted to the PC server of the system and the smartphone of the person concerned, and the person concerned can immediately replace the sprinkling cooling mat described above and constantly monitor and respond to a good cooling function.

According to the digital cooling control system of the present invention, refrigerating cycle devices such as air conditioners, refrigerating devices, refrigerating devices, freezers, refrigerators and vending machines, especially outdoor units equipped with compressors, are used as components. It is possible to exert a significant energy saving effect in the operation of the refrigerating cycle device including the refrigerator.

It is stored and stored in the storage unit of.

Further, the digital cooling control device 21 displayed as a remote control device in FIGS. 1 and 3 includes a digital wind speed meter 15 of the digital cooling device 11, a blowout temperature sensor 16, a water supply amount detection sensor 17, a rain sensor 18, and an outside air temperature. Information detected by each of the sensors 18 and the like is acquired as digital information, and as will be described later, operation control for the blower fan 12 provided in the digital cooling device 11 and opening / closing operation control for the valve provided in the digital cooling device 11 are performed. The water supply operation control to the sprinkling cooling mat 13 and the rotation operation control of the drainage damper, which will be described later, are instructed and executed according to a predetermined computer program.

The digital cooling device 11 includes a blower fan 12, a sprinkler cooling mat 13, a drain damper 14, a digital wind speed meter 15, a blowout temperature sensor 16, a water supply amount detection sensor 17, a rain sensor 18, and an outside air temperature sensor 19.

The blower fan 12, which is indicated as a variable air volume fan in FIG. 3, is arranged outside the air intake portion of the outdoor unit of the refrigeration cycle device equipped with a compressor (indicated as a condenser in FIG. 3). As shown in FIGS. 3 and 4B, the outside air, which is the air outside the outdoor unit, is sent toward the air intake unit to generate an air flow of the outside air in the direction toward the air intake unit. It is a thing.

When the blower fan 12 operates, the air of the outdoor unit is forcibly blown at a wind speed stronger than the wind speed of the air flow in which the outside air is sucked into the outdoor unit from the air suction unit by the action of the compressor (condenser) in the outdoor unit. Outside air can be sent into the suction part. As a result, heat exchange in the compressor (condenser) can be efficiently performed.

As shown in FIGS. 3 and 4 (b), the sprinkler cooling mat 13 is arranged between the blower fan 12 and the air intake portion, and is arranged from the upper side to the lower side in a direction orthogonal to the above-mentioned air flow direction. Moisture flows down in the vertical direction toward the side, and the air flow sent from the blower fan 12 can pass in the direction of the air suction portion.

As the sprinkling cooling mat 13 capable of exhibiting such a function, for example, a porous plate-like body, a sponge-structured plate-like body, a plate-like body made of a non-woven fabric, or the like can be adopted, and these are synthetic resin materials. It can be formed from metal materials and the like.

As will be described later, the valves and solenoid valves in the digital cooling device 11 are controlled to open and close by the instruction and control from the water supply control means 23 of the digital cooling control device 21, which is displayed as a remote control device in FIG. Clean water, medium water, etc. are supplied to 4, and the plate-like body is used as described above in the horizontal direction or diagonally downward direction toward the air suction part of the outdoor unit via the watering nozzle 5. The upper part of a certain watering cooling mat 13 is sprayed with clean water, medium water, or the like to sprinkle water (FIG. 4B). In this way, the sprinkling, sprayed clean water, and reclaimed water flowing onto the upper part of the sprinkling cooling mat 13 which is a plate-like body flows vertically down the inside of the sprinkling cooling mat 13 toward the lower part of the sprinkling cooling mat 13.

On the other hand, as described above, the air flow sent from the blower fan 12 passes through the sprinkler cooling mat 13 into which the clean water and the reclaimed water are flowing down, and toward the air suction portion of the outdoor unit. I will go.

As described above, when the blower fan 12 operates, the wind speed of the outdoor unit is stronger than the wind speed of the air flow in which the outside air is sucked into the outdoor unit from the air suction unit by the action of the compressor (condenser) in the outdoor unit. The outside air can be forcibly sent into the air suction unit, and the heat exchange in the compressor (condenser) can be efficiently performed. In this way, the air flow caused by the blower fan 12 Passes through the sprinkler cooling mat 13 in which moisture flows vertically from the upper side to the lower side, and is sent into the air suction part of the outdoor unit in a state of being cooled to a temperature lower than the outside air temperature. Will be. As a result, heat exchange in the compressor (condenser) can be performed more efficiently.

As shown in FIGS. 3 and 4B, the drainer damper 14 is arranged between the sprinkler cooling mat 13 and the air suction portion.

As described above, the air flow caused by the blower fan 12 passes through the sprinkler cooling mat 13 in which moisture flows vertically from the upper side to the lower side, so that the temperature becomes lower than the outside air temperature. It will be sent into the air suction part in a cooled state. As a result, heat exchange in the compressor (condenser) can be performed more efficiently.

On the other hand, when the air flow sent from the blower fan 12 passes through the sprinkler cooling mat 13 and heads toward the air suction portion of the outdoor unit, the moisture flowing down the sprinkler cooling mat 13 is mixed into the air flow. Then, it may reach the air suction part of the outdoor unit.

The drainer damper 14 removes the moisture from the air flow when the air flow contains moisture, and makes the air stream containing no moisture toward the air suction portion of the outdoor unit.

In the illustrated embodiment, the drain damper 14 has a wind receiving plate 6a located on the side of the blower fan 12 and extending in the horizontal direction (horizontal direction in FIG. 5A) which is a direction orthogonal to the direction of the air flow. It is composed of a wind feed plate 6b located on the side of the air suction portion and extending in the horizontal direction (left-right direction in FIG. 5B), which is a direction orthogonal to the direction of the air flow (FIG. 5).

As shown in FIG. 5C, the wind receiving plate 6a extends obliquely from the lower end edge on the blower fan 12 side toward the upper end edge on the air suction portion side. As shown in FIG. 5C, the air blower plate 6b extends obliquely from the upper end edge on the side of the blower fan 12 toward the lower end edge on the side of the air suction portion.

The upper and lower four-stage drainer damper 14 can be rotated at the same rotation angle in the directions of arrows 6e and 6f around the axis of each damper support shaft 6d by the drainer damper interlocking lever 7 extending in the vertical direction. It has become.

This rotation operation is performed by using the rotation angle adjusting lever 10, and when an arbitrary rotation angle is reached, the angle fixing stopper 9 sets the rotation angle around the axis of the damper support shaft 6d to a predetermined rotation angle. Can be set and fixed to.
