Then, the control device of present embodiment 5 is determined to say in the method whether cooling end 2 generates frosting
It is bright.
Fig. 2 is the humid air line chart being shown in the numerical value for the physical state for indicating humid air on one line chart.
Herein, 25 DEG C will be set as by the air themperature before cooling of cooling end 2 of air-cooling apparatus 1 to be illustrated.In addition,
In the present specification, air themperature is known as dry-bulb temperature.In the feelings that air-flow is flowed along the direction of the arrow A1 of above-mentioned Fig. 1
Under condition, the cooled air themperature before cooling of portion 2 is detected by the first temperature sensor 41.
The cooling capacity of cooling end 2 and the draft capacity of pressure fan 3 are set as, when not generating frosting in cooling end 2
In the case of, the air themperature after cooling of portion 2 that is cooled reduces by 13 DEG C.That is, the cooling capacity of cooling end 2 and sending for pressure fan 3
Wind energy power is set as making the specific enthalpy of air to reduce 13kJ/kg (DA).
As shown in the A point of Fig. 2, the air themperature detected by the first temperature sensor 41 is 25 DEG C, air it is opposite
Humidity is 20%.At this point, being 12 DEG C by the air themperature after cooling of cooling end 2 of air-cooling apparatus 1 as shown in B point.It is cold
But the air themperature after cooling of portion 2 is detected by second temperature sensor 42.In this case, be cooled the sky before cooling of portion 2
The difference of temperature degree and cooled portion 2 air themperature after cooling is the air-supply with the cooling capacity of cooling end 2 and pressure fan 3
The corresponding numerical value of the setting of ability.Therefore, frosting will not be generated in cooling end 2.In addition, in this case, the portion 2 that is cooled is cold
But the specific enthalpy of the air before is 35kJ/kg (DA), and the specific enthalpy for the air after cooling of portion 2 that is cooled is 22kJ/kg (DA).Therefore,
Before cooled portion 2 is cooling and after cooling, the specific enthalpy of air reduces 13kJ/kg (DA).
It in contrast, is 25 DEG C by the air themperature that the first temperature sensor 41 detects as shown in C point, air
Relative humidity is 60%.At this point, being 15 DEG C by the air themperature after cooling of cooling end 2 of air-cooling apparatus 1 as shown in E point.
12 DEG C of high temperature detecting when by the temperature that second temperature sensor 42 detects be than the relative humidity in air being 20%.
In this case, the difference ratio for the air themperature before cooling of portion 2 and the air themperature after cooling of cooled portion 2 of being cooled with it is cold
But the corresponding numerical value of setting of the draft capacity of the cooling capacity and pressure fan 3 in portion 2 is small.Therefore, knot is generated in cooling end 2
Frost.
In detail, when the temperature of the air by cooling end 2 falls below 17 DEG C shown in D point, contained by air
Vapor condensation, to generate frosting.At this point, the cooling energy of cooling end 2 is used for latent heat, the latent heat is for condensing air
Contained vapor, therefore the variation of sensible heat is smaller.In addition, in this case, the ratio for the air before cooling of portion 2 that is cooled
Enthalpy is 56kJ/kg (DA), and the specific enthalpy for the air after cooling of portion 2 that is cooled is 43kJ/kg (DA).Therefore, cooling in cooled portion 2
After preceding and cooled portion 2 is cooling, the specific enthalpy of air reduces 13kJ/kg (DA).
In addition, the dry-bulb temperature shown in the above description, relative humidity, specific enthalpy etc. are only intended to illustrate and illustrate
Numerical value, numerical value include certain amplitude, be not intended to limit function or performance of the air-cooling apparatus 1 etc..
So, control device 5 can be based on the air themperature detected by the first temperature sensor 41 and by second
The air themperature that temperature sensor 42 detects determines whether generate frosting in cooling end 2.Specifically, control device 5 is based on
By the first temperature sensor 41 detect by the air themperature before cooling of cooling end 2, the cooling capacity of cooling end 2 and give
The draft capacity of blower 3 calculates the presumption temperature by the air after cooling of cooling end 2 detected by second temperature sensor 42
Degree.Then, when the air themperature detected by second temperature sensor 42 is higher than presumption temperature, determine to generate in cooling end 2
Frosting.
When control device 5 is judged to reducing or stop the cooling capacity of cooling end 2 when cooling end 2 generates frosting.Or
The draft capacity of person, increase or out-of-blast machine 3.Air-cooling apparatus 1, which is able to suppress, as a result, generates frosting in cooling end 2.

The temperature difference of the air themperature detected by the first temperature sensor 41 and second temperature sensor 42 generates knot in cooling end 2
Value when white is smaller than the value when cooling end 2 does not generate frosting.Therefore, control device 5 can be based on the first temperature sensor 41
Determine whether generate frosting in cooling end 2 with air themperature detected by second temperature sensor 42.Therefore, the cooling dress of air
1 is set compared with using the device of existing humidity sensor or frost sensor, the cost in manufacture can be reduced.

Whether frosting is generated.
The condensation of vapor contained by being not applied to air when the cooling energy generated as cooling end 2 as a result, but
It, can be according to the cooling of cooling end 2 with the temperature difference of air after cooling before cooling by cooling end 2 when being used for the variation of sensible heat
The draft capacity of ability and pressure fan 3 calculates.Therefore, determination unit is to according to the cooling capacity of cooling end 2 and sending for pressure fan 3

Degree difference is compared, and can determine whether cooling end 2 generates frosting.
(3) in first embodiment, control device 5 is cold by cooling end 2 based on being detected by the first temperature sensor 41
But the draft capacity of air themperature, the cooling capacity of cooling end 2 and pressure fan 3 before is calculated by after the cooling of cooling end 2
Air presumption temperature.Then, when by second temperature sensor 42 detect by the air themperature ratio after cooling of cooling end 2
When presumption temperature is high, determine to generate frosting in cooling end 2.
Control device 5 can correctly determine whether generate frosting in cooling end 2 as a result,.
