(motion of Refrigeating plant for container)
It follows that the cooling operating carried out by the Refrigeating plant for container 10 of the first embodiment and dehumidifying are operated into
Row explanation.It addition, for the purpose of simplifying the description, in the following description, it is assumed that second switch valve the 36, the 3rd switch valve the 37, the 4th is opened
Close valve 38 and heater electromagnetic valve 71 is configured to closed mode.
" cooling operating "
Under cooling operating, the first switch valve 35 is in open mode, and reheating electromagnetic valve 70 is closed, expansion valve
The aperture of 76 becomes the aperture of regulation.Further, compressor 21 and storehouse external fan 24 and storehouse internal fan 26 are in driving condition.
The ejection cold-producing medium that compressor 21 is sprayed is transmitted to condenser 23 by high-pressure air pipe 80.Condenser 23 flows
Dynamic cold-producing medium with carry out heat exchange by the air (that is, storehouse external fan 24 the storehouse outer air transmitted) of condenser 23.Its knot
Fruit is, the cold-producing medium in condenser 23 condenses to air (storehouse outer air) heat radiation by condenser 23.
The liquid refrigerant flowed out from condenser 23 flows high-pressure liquid tube 81 and flows in liquid reservoir 73, thus point
For saturated liquid and saturated gas, become the cold-producing medium first high pressure effluent to the first supercooling heat exchanger 60 of saturated liquid
Road 61 is transmitted.
By the cold-producing medium after the first high-pressure side stream 61 of the first supercooling heat exchanger 60 in high-pressure liquid tube 81
Flow and pass through the first switch valve 35.After being kept the skin wet in drying machine 42 by the cold-producing medium after the first switch valve 35, stream
Enter the second high-pressure side stream 64 of the second supercooling heat exchanger 63.The second high-pressure side by the second supercooling heat exchanger 63
Cold-producing medium after stream 64 flows in high-pressure liquid tube 81, and after being depressurized in expansion valve 76, in low hydraulic fluid pipe 82
Flowing also transmits to vaporizer 25.
In vaporizer 25, the cold-producing medium of flowing is (in the storehouse transmitted by storehouse internal fan 26 empty with by the air of vaporizer 25
Gas, i.e. sucks air) carry out heat exchange.As a result of which it is, the cold-producing medium of flowing is from the sky by vaporizer 25 in vaporizer 25
Gas (suction air) absorbs heat and evaporates, and is then cooled by the air (suction air) of vaporizer 25.Flow out from vaporizer 25
Cold-producing medium flow in low pressure gas pipe 83 and pass through air-breathing proportioning valve 66, then sucked by compressor 21 and again compressed.
So, in cooling operating, it is drawn into by suction inlet 51 in the storehouse of container C in storehouse folding and unfolding space S 2
Suction air cooled in vaporizer 25 after, by being in after the reheating heat exchanger 32 of halted state from blow-off outlet 52
Blowout, thus return in storehouse.
Further, in cooling operating, target temperature Tx is set to and design temperature Tsp phase in storehouse by target control portion 201
Deng the first design temperature.Therefore, temperature control part 101 carries out the first cooling action and the second cooling action, in order to blowout is visited
Testing temperature Tss becomes first design temperature equal for design temperature Tsp with in storehouse.
In the case of blowout detection temperature Tss is higher than the first design temperature, temperature control part 101 carries out the first cooling and moves
Make.In the first cooling action, temperature control part 101 makes the aperture of the air-breathing proportioning valve 66 of refrigerant loop 16 increase.Thus,
Circulating mass of refrigerant in refrigerant loop 16 increases, thus the cooling capacity in vaporizer 25 rises.As a result of which it is, lead to successively
The temperature of pervaporation device 25 and reheating heat exchanger 32 after-blow blow out air in the storehouse of container C reduces, thus blows out spy
Testing temperature Tss reduces and close to the first design temperature (that is, design temperature Tsp in storehouse).
On the other hand, in the case of blowout detection temperature Tss is less than the first design temperature, temperature control part 101 is carried out
Second cooling action.In the second cooling action, temperature control part 101 makes the aperture of air-breathing proportioning valve 66 reduce.Thus, refrigeration
Circulating mass of refrigerant in agent loop 16 reduces, thus the cooling capacity in vaporizer 25 reduces.As a result of which it is, pass sequentially through steaming
The temperature sending out device 25 and reheating heat exchanger 32 after-blow blow out air in the storehouse of container C raises, thus blows out detection temperature
Degree Tss raises and close to the first design temperature (that is, design temperature Tsp in storehouse).It addition, in the second cooling action, in order to protect
Protecting compressor 21, the 4th switch valve 38 can also be set to open mode by temperature control part 101.
-supercooling of the cold-producing medium in the first and second supercooling heat exchangers-
It addition, in the case of under cooling operating, second switch valve 36 is configured to open mode, in first, second mistake
Cooling heat exchanger 60,63 carries out supercooling to cold-producing medium.That is, cold-producing medium follows in refrigerant loop 16 as described as follows
Ring.
By the cold-producing medium after the first high-pressure side stream 61 of the first supercooling heat exchanger 60, in above-mentioned cold-producing medium
A part flows to the second arm 86 and passes through second switch valve 36, and on the other hand, remainder flows in high-pressure liquid tube 81
Move and pass through the first switch valve 35.After being depressurized in capillary tube 39 by the cold-producing medium after second switch valve 36, successively
By the second low-pressure side stream 65 and the first low-pressure side of the first supercooling heat exchanger 60 of the second supercooling heat exchanger 63
Stream 62 and flow into the middle port of compressor 21.It addition, in the first supercooling heat exchanger 60, at the first high-pressure side stream
61 and first cold-producing mediums of flowing in low-pressure side stream 62 carry out heat exchange each other, thus flow in the first high-pressure side stream 61
Cold-producing medium be over cooled.
On the other hand, after being kept the skin wet in drying machine 42 by the cold-producing medium after the first switch valve 35, flow into second
Second high-pressure side stream 64 of supercooling heat exchanger 63.In the second supercooling heat exchanger 63, at the second high-pressure side stream
64 and second cold-producing mediums of flowing in low-pressure side stream 65 carry out heat exchange each other, thus flow in the second high-pressure side stream 64
Cold-producing medium be over cooled.Cold-producing medium after being over cooled in the second high-pressure side stream 64 of the second supercooling heat exchanger 63
High-pressure liquid tube 81 flows, and after being depressurized in expansion valve 76, flowing in low hydraulic fluid pipe 82 and be sent to vaporizer
25。
So, in the case of in cooling operating, second switch valve 36 is configured to open mode, the first supercooling heat
Exchanger 60 makes the cold-producing medium of flowing and the cold-producing medium of flowing in the first low-pressure side stream 62 in the first high-pressure side stream 61
Carry out mutually heat exchange, the cold-producing medium of flowing in the first high-pressure side stream 61 is carried out supercooling.Further, the second supercooling
Heat exchanger 63 makes the cold-producing medium of flowing and the refrigeration of flowing in the second low-pressure side stream 65 in the second high-pressure side stream 64
Agent carries out mutually heat exchange, and the cold-producing medium of flowing in the second high-pressure side stream 64 is carried out supercooling.
" dehumidifying operating (the first Dehumidification controlling) "
If the operation mode of Refrigeating plant for container 10 switches to dehumidifying operating from cooling operating, then carry out first and remove
Wet control, reheating electromagnetic valve 70 becomes open mode.It addition, in the first Dehumidification controlling, the first switch valve 35 is in opens shape
State, the aperture of expansion valve 76 becomes the aperture of regulation, compressor 21 and storehouse external fan 24 and storehouse internal fan 26 is in driving shape
State.
In dehumidifying operating, the part from the cold-producing medium of compressor 21 ejection flows in the second connecting tube 92, and
By flowing into (flowing directly into) reheating heat exchanger 32 after reheating electromagnetic valve 70.On the other hand, from the refrigeration of compressor 21 ejection
Remainder (that is, not flowing into the cold-producing medium of the second connecting tube 92) in agent then with cooling operating in the same manner as at condenser 23
Middle condensation, evaporation in vaporizer 25 after expansion in expansion valve 76.That is, in vaporizer 25 flowing cold-producing medium with pass through
The air (in the storehouse transmitted by storehouse internal fan 26, air, i.e. sucks air) of vaporizer 25 carries out heat exchange.As a result of which it is, steaming
Send out the cold-producing medium of flowing in device 25 to evaporate from air (suction air) heat absorption by vaporizer 25, and by vaporizer 25
Air (suction air) is then cooled and condenses.Therefore, air is sucked dehumidified.
On the other hand, in reheating heat exchanger 32, the cold-producing medium (high-pressure gaseous refrigerant) of flowing is handed over by reheating heat
The air (that is, the cooled air dehumidified in vaporizer 25) of parallel operation 32 carries out heat exchange.As a result of which it is, hand in reheating heat
In parallel operation 32, the cold-producing medium (high-pressure gaseous refrigerant) of flowing condenses to the air heat radiation by reheating heat exchanger 32, passes through
The air of reheating heat exchanger 32 is heated.
So, in dehumidifying operating, it is drawn into by suction inlet 51 in the storehouse of container C in storehouse folding and unfolding space S 2
Suction air heated in reheating heat exchanger 32 after cooled dehumidifying in vaporizer 25, and blow from blow-off outlet 52
Go out, thus return in storehouse.
Further, if the operation mode of Refrigeating plant for container 10 switches to dehumidifying operating (if i.e., from cooling operating
Carry out the first Dehumidification controlling), then target temperature Tx is set to and is added with target by design temperature Tsp in storehouse by goal setting section 102
Calculate the second design temperature obtained by temperature addition.Thus, temperature control part 101 carries out the first cooling action and the second cooling is dynamic
Make, in order to blowout detection temperature Tss become temperature that design temperature Tsp in storehouse is added with target is added obtained by the second setting warm
Degree.
In the case of blowout detection temperature Tss is higher than the second design temperature, temperature control part 101 carries out the first cooling and moves
Make.Thus, the cooling capacity in vaporizer 25 rises, as a result of which it is, after passing sequentially through vaporizer 25 and reheating heat exchanger 32
The temperature blowing to the blow out air in the storehouse of container C reduces, thus blows out detection temperature Tss and reduce and set temperature close to second
Degree (that is, the temperature that design temperature Tsp in storehouse added with target be added obtained by temperature).
On the other hand, in the case of blowout detection temperature Tss is less than the second design temperature, temperature control part 101 is carried out
Second cooling action.Thus, the cooling capacity in vaporizer 25 reduces, as a result of which it is, pass sequentially through vaporizer 25 and reheating heat
The temperature of exchanger 32 after-blow blow out air in the storehouse of container C raises, thus blows out detection temperature Tss and raise and close
Second design temperature (that is, the temperature that design temperature Tsp in storehouse added with target be added obtained by temperature).
By carrying out temperature control in this manner, even if the temperature of blow out air is because of in reheating heat exchanger 32
Heat and rise and cause blowout detection temperature Tss higher than target temperature Tx, it is also possible to cool down by the first of temperature control part 101
Action makes the cooling capacity in vaporizer 25 rise, and makes the temperature of blow out air reduce.Thereby, it is possible in suppression dehumidifying operating
The temperature of blow out air rises.
" the second Dehumidification controlling "
Even if being dehumidified by the first Dehumidification controlling, the most insufficient to the dehumidifying of air in the storehouse of container C
In situation (that is, sucking detection humidity in the first Dehumidification controlling higher than the situation of target humidity), operation control section 105 terminates the
One Dehumidification controlling and carry out the second Dehumidification controlling.Wherein, in the second Dehumidification controlling, the first switch valve 35 and reheating electromagnetic valve 70
Being in open mode, the aperture of expansion valve 76 becomes the aperture of regulation, compressor 21 and storehouse external fan 24 and storehouse internal fan 26
It is in driving condition.
Further, in the second Dehumidification controlling, target temperature Tx is configured to the second design temperature (by design temperature in storehouse
Tsp add with target temperature be added obtained by temperature).That is, temperature control part 101 carries out the first cooling action and the second cooling is dynamic
Make, in order to blowout detection temperature Tss becomes the second design temperature.
Further, in the second Dehumidification controlling, operation control section 105 is according to dehumidifying load setting target ejection pressure, in order to
Dehumidifying load is the biggest, then target ejection pressure is the biggest.Then, operation control section 105 detects according to by high-pressure pressure sensor 111
To the ejection pressure of compressor 21 control the start-stop of storehouse external fan 24.Specifically, if by high-pressure pressure sensor 111
The ejection pressure of the compressor 21 detected sprays pressure less than target, then operation control section 105 makes storehouse external fan 24 stop.By
This, the heat exchange in condenser 23 is hindered, and the ejection pressure of compressor 21 increases.On the other hand, if by high-pressure
The ejection pressure of the compressor 21 that sensor 111 detects sprays pressure higher than target, then operation control section 105 is by storehouse external fan
24 drive.Thus, the heat exchange in condenser 23 is promoted, and the ejection pressure of compressor 21 reduces.That is, target ejection pressure
The biggest, then the ejection pressure of compressor 21 is the biggest.
It addition, the ejection pressure of compressor 21 is the biggest, then the pressure of the cold-producing medium flowing into reheating heat exchanger 32 is the biggest, its
Result is, the heating efficiency in reheating heat exchanger 32 raises.Further, if the temperature of blow out air is because of reheating heat exchanger 32
In the rising and raising of heating efficiency cause blowout detection temperature Tss higher than target temperature Tx, then temperature control part 101 in order to
Blowout detection temperature Tss is made to reduce and carry out the first cooling action.Thus, the cooling capacity in vaporizer 25 rises and blows out sky
The temperature of gas reduces, as a result of which it is, blowout detection temperature Tss reduces and close to target temperature Tx.Further, if in vaporizer 25
Cooling capacity rise, then in vaporizer 25 condensation water quantities increase.That is, the dehumidifying effect in vaporizer 25 rises.
So, according to dehumidifying load setting target ejection pressure, it is possible to according in dehumidifying load setting vaporizer 25
Dehumidifying effect, in order to dehumidifying load the biggest, then the dehumidifying effect in vaporizer 25 is the highest.
In the second Dehumidification controlling, the control to cooling end 18 by temperature control part 101 and operation control section 105, comes
The heating efficiency in reheating heat exchanger 32 is made to rise and make steaming in the way of blowout detection temperature Tss becomes target temperature Tx
Send out the cooling capacity in device 25 to rise such that it is able to make the dehumidifying effect in vaporizer 25 increase.
" the 3rd Dehumidification controlling "
In the case of under the first Dehumidification controlling, blowout detection temperature Tss rises, operation control section 105 terminates first and removes
Wet control and carry out the 3rd Dehumidification controlling.In the 3rd Dehumidification controlling, reheating electromagnetic valve 70 is closed.It addition,
In three Dehumidification controllings, the first switch valve 35 is in open mode, and the aperture of expansion valve 76 becomes the aperture of regulation, compressor 21 He
Storehouse external fan 24 and storehouse internal fan 26 are in driving condition.
In the 3rd Dehumidification controlling, as cooling operating, the ejection cold-producing medium of compressor condenses in condenser 23,
Evaporate in vaporizer 25 after expansion valve 76 expands.That is, by the air (suction air) of vaporizer 25 with vaporizer
It is cooled after the cold-producing medium of flowing carries out heat exchange in 25 and condenses.So, the suction air being drawn in the storehouse of container C
Cooled dehumidifying in vaporizer 25.
Further, in the 3rd Dehumidification controlling, target temperature Tx is set to and design temperature in storehouse by goal setting section 102
The first equal for Tsp design temperature.Therefore, temperature control part 101 carries out the first cooling action and the second cooling action, in order to blow
Go out to detect temperature Tss and become the first design temperature.
(temperature of blow out air is along with the change switching to dehumidifying operating from cooling operating)
It addition, in dehumidifying operating, by the air of heater 17 (in this embodiment, being reheating heat exchanger 32) sometimes
It is not uniformly heated.Such as, due to the heat-transfer pipe (heat transfer extended along insied width direction, storehouse of reheating heat exchanger 32
Pipe) in cold-producing medium there is temperature difference, therefore produce the feelings of blow out air non-uniform temperature from reheating heat exchanger 32 blowout
Condition.If switching to dehumidifying operating from cooling operating in this case, then it is difficult by blowing out temperature sensor 34 accurate
The minimum temperature of the blow out air on detection insied width direction, storehouse, ground.Such as, as it is shown in figure 9, set when blowing out temperature sensor 34
In the case of putting the central part on the insied width direction, storehouse of container C, and, when with the central part phase on insied width direction, storehouse
Blowing of the central part that the blow out air of the part that ratio is slightly closer to end is on minimum temperature rather than insied width direction, storehouse
Go out in the case of air is in minimum temperature, blowout temperature sensor 34 temperature (that is, the blowout detection of the blow out air detected
Temperature Tss) higher than the actual minimum of the blow out air on insied width direction, storehouse.
On the other hand, in the Refrigeating plant for container 10 involved by the first embodiment, when from cooling operating switching
In the case of becoming dehumidifying operating, target temperature Tx is configured to second design temperature higher than design temperature in storehouse (that is, by storehouse
Design temperature Tsp add with target temperature be added obtained by temperature), therefore, it is possible to make on the whole to blow in the storehouse of container C
The temperature of blow out air raises.Thus, though by the air of heater 17 on the insied width direction, storehouse of container C not
Be be uniformly heated in the case of, it is also possible to the minimum temperature of blow out air on the insied width direction, storehouse of suppression container C
Less than design temperature Tsp in storehouse.
(correction to target temperature of first correcting section)
It follows that the correction that target temperature Tx is carried out by explanation by the first correcting section 103.As it has been described above, the first correcting section
103 monitor the temperature (that is, sucking detection temperature Trs) sucking air detected by inlet temperature sensor 33, at container
With the operation mode of refrigerating plant 10 after cooling operating switches to dehumidifying operating, if sucking detection temperature Trs higher than inhaling
Enter fiducial temperature, then the first correcting section 103 makes target temperature Tx reduce, on the other hand, if sucking detection temperature Trs less than inhaling
Enter fiducial temperature, then the first correcting section 103 makes target temperature Tx raise.
Circulate in the storehouse of container C it addition, blow to the air in the storehouse of container C from vaporizer 25 and heater 17
And be again drawn in vaporizer 25.Therefore, suck in the storehouse of container C sucks the air storehouse insied width at container C
Non-uniform temperature degree on direction is less than the blow out air in the storehouse blowing to container C in the insied width direction, storehouse of container C
On non-uniform temperature degree.Further, the change sucking detection temperature Trs depends on the change of storehouse temperature of container C.Tool
For body, if the storehouse temperature of container C raises, then the temperature sucking air raises, thus sucks detection temperature Trs liter
High.On the other hand, if the storehouse temperature of container C reduces, then the temperature sucking air reduces, thus sucks detection temperature
Trs reduces.Therefore, after switching to dehumidifying operating from cooling operating, when sucking detection temperature Trs higher than sucking fiducial temperature
(it is in this embodiment, to suck equilibrium temperature Trs ') in the case of, it is possible to judge that the storehouse temperature of container C raises, work as suction
In the case of detection temperature Trs is less than sucking fiducial temperature, it is possible to judge that the storehouse temperature of container C reduces.
Then, in the Refrigeating plant for container 10 involved by the first embodiment, as it has been described above, the first correcting section
103 according to the change sucking detection temperature Trs before and after switching to dehumidifying operating from cooling operating, and make corrections target temperature Tx.
That is, if after switching to dehumidifying operating from cooling operating, the storehouse temperature of container C rises and causes sucking detection temperature Trs
Higher than suck fiducial temperature (in this embodiment, be suck equilibrium temperature Trs '), then the first correcting section 103 makes target temperature Tx drop
Low.Thereby, it is possible to make the temperature of blow out air reduce, as a result of which it is, the storehouse temperature of container C can be made to reduce.The opposing party
Face, if the storehouse temperature of container C reduces and causes sucking detection temperature Trs after switching to dehumidifying operating from cooling operating
Less than sucking fiducial temperature, then the first correcting section 103 makes target temperature Tx raise.Thereby, it is possible to make in the temperature of blow out air
Rise, as a result of which it is, the storehouse temperature of container C can be made to rise.
So, control to blow according to the change sucking detection temperature Trs before and after switching to dehumidifying operating from cooling operating
Go out the temperature of air, it is possible to the storehouse temperature suppressing container C and become along with switching to dehumidifying operating from cooling operating
Change.
(by the correction to target temperature of second correcting section)
It follows that the correction that target temperature is carried out by explanation by the second correcting section 104.As it has been described above, in this embodiment, second
Correcting section 104 monitors and is detected by high-pressure pressure sensor 111 in dehumidifying operating (specifically, being the second Dehumidification controlling)
The ejection pressure of compressor 21, and make corrections target temperature Tx according to the ejection pressure of compressor 21, in order to the spray of compressor 21
Go out pressure the highest, then target temperature Tx is the highest.
It addition, the dehumidifying effect in vaporizer 25 depends on the ejection pressure of compressor 21.That is, the ejection pressure of compressor 21
Power is the highest, then the pressure of the cold-producing medium flowing into reheating heat exchanger 32 is the highest, as a result of which it is, the heating in reheating heat exchanger 32
Ability rises.Further, the temperature of blow out air raises because of the rising of the heating efficiency in reheating heat exchanger 32, thus blows out
Detection temperature Tss is higher than target temperature Tx.Then, temperature control part 101 controls cooling end 18 so that blowout detection temperature Tss drops
Low, make the cooling capacity in vaporizer 25 increase.Thus, the dehumidifying effect in vaporizer 25 rises.
So, the dehumidifying effect in vaporizer 25 depends on the ejection pressure of compressor 21, therefore according to compressor 21
Ejection pressure makes corrections target temperature Tx, it is possible to by target temperature Tx correction is: the dehumidifying effect in vaporizer 25 is the highest,
Then target temperature Tx is the highest.
In dehumidifying operating, air is cooled in vaporizer 25 and condenses, and thus dehumidifies air.That is, removing
Under wet operating, there is following tendency: the dehumidifying effect (cooling capacity) in vaporizer 25 is the highest, then the temperature of blow out air is more held
Easily decline.
And, in the Refrigeating plant for container 10 involved by the first embodiment, as it has been described above, the second correcting section
104 make corrections target temperature Tx according to the dehumidifying effect in vaporizer 25 under dehumidifying operating, in order to the dehumidifying in vaporizer 25
Ability is the highest, then target temperature Tx is the highest.Thus, in the case of in dehumidifying operating, the temperature of blow out air easily declines,
The temperature that can make blow out air raises.
(effect of the first embodiment)
As it has been described above, in the Refrigeating plant for container 10 involved by the first embodiment, from cooling operating switching
In the case of becoming dehumidifying operating, by target temperature Tx is set to second design temperature higher for design temperature Tsp than in storehouse
(that is, the temperature that design temperature Tsp in storehouse and target maked corrections be added obtained by temperature), thus, even if by heater 17 (
In this example, be reheating heat exchanger 32) air be not situation about being uniformly heated on the insied width direction, storehouse of container C
Under, it is also possible to the minimum temperature of the blow out air on the insied width direction, storehouse of suppression container C is lower than design temperature Tsp in storehouse.
Thereby, it is possible to prevent low temperature from the goods of container C being had undesirable effect.
Additionally, according to after being switched to dehumidifying operating from cooling operating suck detection temperature Trs change (concrete and
Speech, be suck detection temperature Trs with suck equilibrium temperature Trs ' comparative result), make corrections target temperature Tx, it is possible to press down
The storehouse temperature of container C processed changes along with switching to dehumidifying operating from cooling operating.Thus, in dehumidifying operating, both
Preventing low temperature from having undesirable effect the goods of container C, the storehouse temperature being prevented from again container C rises.
Additionally, by the suction fiducial temperature being used for judging to suck the change of detection temperature Trs is set to that suction is stable
Temperature Trs ', it is possible to suck equilibrium temperature Trs ' on the basis of, judge the collection before and after cooling operating switches to dehumidifying operating
Whether the change of the storehouse temperature of vanning C causes the change sucking detection temperature Trs.
Additionally, come according to the dehumidifying effect in vaporizer 25 under dehumidifying operating (specifically, being the second Dehumidification controlling)
Correction target temperature Tx, thus in the case of in dehumidifying operating, the temperature of blow out air easily declines, it is possible to makes blowout empty
The temperature of gas raises.Thereby, it is possible to suppression container C storehouse temperature along with the dehumidifying effect in vaporizer 25 rising and
Reduce.
Additionally, by by design temperature Tsp in lower limit set Cheng Ku of target temperature Tx, it is possible to prevent the temperature of blow out air
Spend in reduction.Thereby, it is possible to prevent the storehouse temperature of container C from excessively reducing, therefore, it is possible to be reliably prevented in dehumidifying fortune
In turning, the goods of container C is had undesirable effect by low temperature.
Additionally, in the Refrigeating plant for container 10 involved by the first embodiment, in dehumidifying operating (specifically,
It is the first Dehumidification controlling) under, it is possible in vaporizer 25, the suction air being drawn in the storehouse of container C is carried out cooling and remove
Wet and in reheating heat exchanger 32, above-mentioned suction air is heated.Thus, the storehouse temperature of container C can either be suppressed
Reduce, it is also possible to air in the storehouse of container C is dehumidified.
Additionally, in the Refrigeating plant for container involved by the first embodiment, in dehumidifying operating (specifically, be
Second Dehumidification controlling) in, it is possible to make in reheating heat exchanger 32 in the way of blowout detection temperature Tss becomes target temperature Tx
Heating efficiency rises and makes the cooling capacity in vaporizer 25 increase, and makes the dehumidifying effect in vaporizer 25 increase, therefore
The dehumidifying effect in vaporizer 25 can be made to increase while suppressing the change of the storehouse temperature of container C.
(variation of operation control section)
It addition, operation control section 105 msy be also constructed to as follows: it monitors the degree of superheat in vaporizer 25, and controls
The aperture of the expansion valve 76 of cooling end 18, in order to the degree of superheat in vaporizer 25 becomes the target superheat degree preset.Tool
For body, operation control section 105 is configured to as follows: when the degree of superheat in vaporizer 25 is less than the situation of target superheat degree
Under, operation control section 105 makes the aperture reduction of expansion valve 76 make the degree of superheat in vaporizer 25 raise；When in vaporizer 25
The degree of superheat is higher than in the case of target superheat degree, and operation control section 105 makes the aperture increase of expansion valve 76 to make in vaporizer 25
The degree of superheat reduce.
And then, in the second Dehumidification controlling, in the case of the ejection pressure of compressor 21 reaches maximum (ultimate value),
Operation control section 105 can also make the dehumidifying effect in vaporizer 25 rise by the action being discussed below.That is, operating
Control portion 105 msy be also constructed to as follows: in the second Dehumidification controlling, and operation control section 105 monitors dehumidifying load, and according to removing
Humidity load carrys out the target setting degree of superheat, in order to dehumidifying load is the biggest, then target superheat degree is the highest.Such as, increase along with dehumidifying load
Greatly, operation control section 105 can make target superheat degree with " 2 DEG C ", " 5 DEG C ", " 8 DEG C ", " 11 DEG C ", the sequential stages of " 14 DEG C "
Ground raises.
If the degree of superheat in vaporizer 25 raises, then the suction pressure of compressor 21 reduces, thus the going out of vaporizer 25
Mouth evaporating temperature reduces.Thus, in vaporizer 25, the water quantities of condensation increases.If it addition, the suction pressure of compressor 21
Reduce, then in vaporizer 25, the specific volume of the cold-producing medium of flowing increases, thus the circulating mass of refrigerant in refrigerant loop 16 subtracts
Few, as a result of which it is, the cooling capacity in vaporizer 25 reduces, thus the temperature of blow out air rises.And, if blow out air
Temperature rise and cause blowout detection temperature Tss higher than target temperature Tx, then temperature control part 101 carries out the first cooling action
(it is specifically, to make the aperture of air-breathing proportioning valve 66 increase to make what the circulating mass of refrigerant in refrigerant loop 16 increased to move
Make).Thus, the cooling capacity in vaporizer 25 rises and the temperature of blow out air reduces, as a result of which it is, blowout detection temperature
Tss reduces and close to target temperature Tx.
So, carry out the target setting degree of superheat according to dehumidifying load, it is possible to set vaporizer 25 according to dehumidifying load
In dehumidifying effect, in order to dehumidifying load the biggest, then the dehumidifying effect in vaporizer 25 is the highest.
Further, by control cooling end 18 carried out by temperature control part 101 and operation control section 105, it is possible to blow
Go out to detect temperature Tss to become the mode of target temperature Tx and make the outlet evaporating temperature of vaporizer 25 reduce and make refrigerant loop
Circulating mass of refrigerant in 16 increases, therefore, it is possible to the change of the storehouse temperature of suppression container C, while making vaporizer 25
In dehumidifying effect rise.
(the second embodiment)
It follows that the Refrigeating plant for container 10 involved by the second embodiment is illustrated.The second embodiment party
In Refrigeating plant for container 10 involved by formula, sucking fiducial temperature is not to be configured to suck equilibrium temperature Trs ', but
The temperature that is configured to add design temperature Tsp in storehouse with the suction preset sucks design temperature (i.e., obtained by being added
The value of the setting value (design temperature Tsp in storehouse) of storehouse temperature based on container C).That is, dehumidifying is being switched to from cooling operating
After operating, if sucking detection temperature Trs higher than sucking design temperature, then the first correcting section 103 makes target temperature Tx reduce,
On the other hand, if sucking detection temperature Trs less than sucking design temperature, then the first correcting section 103 makes target temperature Tx raise.
Other compositions are then identical with the Refrigeating plant for container 10 involved by the first embodiment.
It addition, as sucking fiducial temperature, it is also possible to sets two kinds and suck fiducial temperatures (the first suction fiducial temperature and the
Two suck fiducial temperature).I.e., it is possible to set for judge suck detection temperature Trs rising first suction fiducial temperature and
For judging to suck the second suction fiducial temperature of the reduction of detection temperature Trs.For example, it is also possible to be: first sucks benchmark temperature
Degree be configured to by design temperature Tsp in storehouse with first suck add temperature (such as+3.0 DEG C) be added obtained by first suction set
Fixed temperature, second sucks fiducial temperature is configured to design temperature Tsp in storehouse and second suck the temperature that adds (less than the first suction
Enter the temperature of temperature that adds, such as+0.5 DEG C) be added obtained by second suck design temperature.
Such as, if the first suction fiducial temperature is configured to design temperature Tsp in storehouse and first is sucked the temperature that adds
(+3.0 DEG C) be added obtained by first suck design temperature (that is, " Tsp+3.0 DEG C "), second suck fiducial temperature be configured to by
In storehouse, design temperature Tsp and second sucks the second suction design temperature (that is, " Tsp+ obtained by temperature (+0.5 DEG C) addition that adds
0.5 DEG C "), target temperature Tx before the correction temperature (+0.6 DEG C) that is configured to add design temperature Tsp in storehouse with target is added
Obtained by the second design temperature (that is, Tsp+0.6 DEG C), represent negative value first correction temperature Y be configured to "-0.2 DEG C ", table
Show on the occasion of first correction temperature Y be configured to "+0.2 DEG C ", then the first correcting section 103 is as described as follows to target temperature Tx
Make corrections.
That is, after switching to dehumidifying operating from cooling operating, when sucking detection temperature Trs higher than the first suction benchmark temperature
In the case of degree (Tsp+3.0 DEG C), the first correcting section 103 is by target temperature Tx and the first correction temperature (-0.2 representing negative value
DEG C) be added.Thus, target temperature Tx becomes " Tsp+0.6 DEG C-0.2 DEG C ".Then, even if by this correction, dehumidifying is switched to
In the case of suction detection temperature Trs after operating is still higher than the first suction fiducial temperature (Tsp+3.0 DEG C), the first correction
Target temperature Tx after correction is added by portion 103 with the first correction temperature (-0.2 DEG C) representing negative value again.Thus, target temperature
Degree Tx becomes " Tsp+0.6-(0.2 DEG C × 2) ".
On the other hand, after switching to dehumidifying operating from cooling operating, when sucking detection temperature Trs less than the second suction
In the case of fiducial temperature (Tsp+0.5 DEG C), the first correcting section 103 by target temperature Tx with represent on the occasion of first correction temperature
(+0.2 DEG C) is added.Thus, target temperature Tx becomes " Tsp+0.6 DEG C+0.2 DEG C ".Then, even if by this correction, switching to
In the case of suction detection temperature Trs after dehumidifying operating is still less than the second suction fiducial temperature (Tsp+0.5 DEG C), first
Correcting section 103 will correction after target temperature Tx with represent on the occasion of first make corrections temperature (+0.2 DEG C) be added again.Thus, target
Temperature Tx becomes " Tsp+0.6+ (0.2 DEG C × 2) ".
(effect of the second embodiment)
As it has been described above, by the suction fiducial temperature being used for judging to suck the change of detection temperature Trs is set to suction
Design temperature (that is, the temperature that design temperature Tsp in storehouse added with suction be added obtained by temperature), it is possible to suck design temperature
On the basis of, judge whether the change of the storehouse temperature of the container C after cooling operating is switched to dehumidifying operating causes
Suck the change of detection temperature Trs.
It addition, other effects, effect and the first enforcement that the Refrigeating plant for container 10 of the second embodiment is played
Effect, effect that the Refrigeating plant for container 10 of mode is played are identical.

The heating capacity (steady state value) of the electric heater 78 in the first Dehumidification controlling.
" the 3rd Dehumidification controlling "
In the 3rd Dehumidification controlling, operation control section 105 makes electric heater 78 stop.It addition, it is same with the first embodiment
Sample, in the 3rd Dehumidification controlling, the first switch valve 35 is set to open mode, opening expansion valve 76 by operation control section 105
Degree is set to the aperture of regulation, compressor 21 and storehouse external fan 24 and storehouse internal fan 26 is set to driving condition.
(motion of Refrigeating plant for container)
It follows that the cooling operating carried out by the Refrigeating plant for container 10 of the 3rd embodiment and dehumidifying are operated into
Row explanation.It addition, the correction carried out target temperature Tx by the first correcting section 103 and the second correcting section 104 is then implemented with first
Mode is identical.It addition, for the purpose of simplifying the description, in the following description, it is assumed that second switch valve the 36, the 3rd switch valve the 37, the 4th
Switch valve 38 and heater electromagnetic valve 71 are configured to closed mode.
" cooling operating "
In cooling operating, electric heater 78 stops, and the first switch valve 35 is in the aperture quilt of open mode, expansion valve 76
It is set to the aperture of regulation.Further, compressor 21 and storehouse external fan 24 and storehouse internal fan 26 become driving condition.Thus, exist
In cooling operating, the suction air being drawn in storehouse folding and unfolding space S 2 by suction inlet 51 in the storehouse of container C is in evaporation
It is blown from blow-off outlet 52 by being in the electric heater 78 of halted state after device 25 is cooled, thus returns in storehouse.
Further, as the first embodiment, in cooling operating, target temperature Tx is set to by target control portion 201
First design temperature equal for design temperature Tsp with in storehouse.Therefore, temperature control part 101 with blowout detection temperature Tss become with
The mode of the first design temperature equal for design temperature Tsp in storehouse carries out the first cooling action and the second cooling action.
" dehumidifying operating (the first Dehumidification controlling) "
If the operation mode of Refrigeating plant for container 10 switches to dehumidifying operating from cooling operating, then carry out first and remove
Wet control, electric heater 78 is driven.It addition, in the first Dehumidification controlling, the first switch valve 35 is in open mode, expand
The aperture of valve 76 becomes the aperture of regulation, compressor 21 and storehouse external fan 24 and storehouse internal fan 26 is in driving condition.
In dehumidifying operating, same with cooling operating, the cold-producing medium sprayed from compressor 21 condenses condenser 23,
Evaporate in vaporizer 25 after expansion valve 76 expands.That is, in vaporizer 25 flowing cold-producing medium with by vaporizer 25
Air (in the storehouse transmitted by storehouse internal fan 26, air, i.e. sucks air) carry out heat exchange.As a result of which it is, in vaporizer 25
The cold-producing medium of flowing evaporates from air (suction air) heat absorption by vaporizer 25, (is sucked by the air of vaporizer 25
Air) then it is cooled and condenses.Therefore, air is sucked dehumidified.On the other hand, the air passed through at electric heater 78 (that is, exists
Air after cooled dehumidifying in vaporizer 25) it is electrically heated device 78 and heats.
So, in dehumidifying operating, in the storehouse of container C, it is drawn into folding and unfolding space S 2 in storehouse by suction inlet 51
Sucking air, above-mentioned suction air is heated and from blow-off outlet after cooled dehumidifying in vaporizer 25 in electric heater 78
52 are blown, thus return in storehouse.
Further, if the operation mode of Refrigeating plant for container 10 switches to dehumidifying operating (if i.e., from cooling operating
Carry out the first Dehumidification controlling), then target temperature Tx is set to and is added with target by design temperature Tsp in storehouse by goal setting section 102
Calculate the second design temperature obtained by temperature addition.Therefore, temperature control part 101 carries out the first cooling action and the second cooling is dynamic
Make, in order to blowout detection temperature Tss become temperature that design temperature Tsp in storehouse is added with target is added obtained by the second setting warm
Degree.
By carrying out temperature control in this manner, though adding of carrying out of the temperature reason electric heater 78 of blow out air
Hot and rising causes blowout to detect temperature Tss and is higher than target temperature Tx, it is also possible to cools down by the first of temperature control part 101 and moves
Make the cooling capacity in vaporizer 25 increase, make the temperature of blow out air reduce.Thereby, it is possible to suppression dehumidifying operating is blown
The temperature going out air rises.
" the second Dehumidification controlling "
Even if being dehumidified by the first Dehumidification controlling, the most insufficient to the dehumidifying of air in the storehouse of container C
In situation (that is, sucking the detection humidity situation higher than target humidity in the first Dehumidification controlling), operation control section 105 terminates first
Dehumidification controlling and carry out the second Dehumidification controlling.It addition, in the second Dehumidification controlling, electric heater 78 is driven, the first switch
Valve 35 is in open mode, and the aperture of expansion valve 76 becomes the aperture of regulation, compressor 21 and storehouse external fan 24 and storehouse endogenous wind
Fan 26 is in driving condition.
Further, in the second Dehumidification controlling, target temperature Tx is configured to the second design temperature (by design temperature in storehouse
Tsp add with target temperature be added obtained by temperature).That is, temperature control part 101 carries out the first cooling action and the second cooling is dynamic
Make, in order to blowout detection temperature Tss becomes the second design temperature.
Further, in the second Dehumidification controlling, operation control section 105 sets the heating of electric heater 78 according to dehumidifying load
Capacity, in order to dehumidifying load is the biggest, then the heating capacity of electric heater 78 is the biggest.It addition, the heating capacity of electric heater 78 is more
