But the refrigeration of the temperature of device 61 chiller temperature sensor 19, panel 16 etc..Control unit 12 is obtained based on these test sections
Testing result control each several part of electrical connection.On control unit 12, in addition to these parts, it can also be electrically connected as needed
Connect various parts.
Control unit 12 is alternately cooled refrigerating space and reefer space.At cooling and refrigeration space, the operation switching of control unit 12
Valve 66 and coolant flow is produced cold air with cooler 61 to refrigeration, meanwhile, rotate refrigeration Air Blast fan 62, will refrigerate
Cold air conveys to refrigerating space caused by cooler 61.The cooling of the refrigerating space so carried out is referred to as to refrigerate cooling.
In addition, when cooling down reefer space, control unit 12 operates switching valve 66 and coolant flow is produced to freezing with cooler 71
Cold air, meanwhile, rotate freezing Air Blast fan 72, the cold air caused by cooler 71 conveys to reefer space by freezing.
The cooling of the reefer space so carried out is referred to as to freeze cooling.Control unit 12 performed when meeting switching condition freezing cooling and
Refrigerate the switching of cooling.So-called switching condition is, for example, the space cooled down at that time temperature below set point of temperature, at that time not
The cooling in the space that the temperature in the space of cooling had cooled down more than set point of temperature or at that time continues stipulated time etc..
In the refrigerator 10, if the reserve frozen is put into the upper strata container 24 of shock chamber 23 by user, press
The defrosting mode key of panel 16, then control unit 12 start to be operated with defrosting pattern.In defrosting pattern, no matter in freezing
In cooling or in refrigeration cooling, control unit 12 rotates refrigeration Air Blast fan 62.Also, control unit 12 is in defrosting pattern
In make refrigeration Air Blast fan 62 rotating speed be more than defrosting pattern beyond when refrigeration cooling in rotating speed.It is cold in defrosting pattern
The difference hidden between the rotating speed in refrigeration cooling when beyond rotating speed (rpm) and defrosting pattern with Air Blast fan 62 is, for example, to solve
Refrigerate the rotating speed in cooling more than 5% and less than 15% when beyond jelly pattern.So, control unit 12 improves refrigeration air-supply
The rotating speed of fan 62, thus, the amount of the cold air conveyed into the upper strata container 24 as the shock chamber 23 of defrosting room increase.
Preferably, control unit 12 makes the refrigeration in freezing cooling be more than with the rotating speed of Air Blast fan 62 cold in defrosting pattern
Hide the rotating speed of the refrigeration Air Blast fan 62 in cooling.For example, control unit 12 makes refrigeration in defrosting pattern and in refrigeration cooling
Refrigerate the rotating speed in cooling more than 5% and less than 10% when rotating speed with Air Blast fan 62 is beyond defrosting pattern, accordingly
Ground is larger than the rotating speed in refrigeration cooling when beyond defrosting pattern.In addition, control unit 12 is in defrosting pattern and freezing is cold
But make in refrigeration be defrosting pattern with the rotating speed of Air Blast fan 62 beyond when refrigeration cooling in rotating speed more than 10% and
Less than 15%, the rotating speed being correspondingly larger than in refrigeration cooling when beyond defrosting pattern.Enumerate more specifically example：Control
Portion 12 make the rotating speed of refrigeration Air Blast fan 62 in defrosting pattern and freeze cooling in be 1700rpm, in defrosting pattern and
It is 1600rpm in refrigeration cooling, is 1500rpm in refrigeration cooling when beyond defrosting pattern.Thus, refrigeration Air Blast fan
62 rotating speed successively in defrosting pattern and freezing cooling in, in defrosting pattern and refrigeration cooling in, beyond defrosting pattern when
It is gradually reduced in refrigeration cooling.But control unit 12 can also make refrigeration Air Blast fan 62 in defrosting pattern and freeze cold
But the rotating speed in is identical with the rotating speed in defrosting pattern and in refrigeration cooling.
Control unit 12 in addition to rotating speed of the refrigeration with Air Blast fan 62 is improved, can also be carried out following in defrosting pattern
More than any one in additional control 1~3 control.
Additional control 1 is the control for the amount that control unit 12 reduces the cooling agent for flowing into refrigeration cooler 61.As reduction
The method of the amount of cooling agent, such as can enumerate：Reduce the method for the operating frequency of compressor 64, with refrigeration decompressor 63
The method for reducing the amount of cooling agent.In the case where reducing the operating frequency of compressor 64, such as it is reduced to beyond defrosting pattern
When operating frequency 2/3 or so.In addition, the method as the amount that cooling agent is reduced with refrigeration decompressor 63, such as can
To enumerate：Expansion valve is set as refrigeration decompressor 63 and to reduce the method for the aperture of expansion valve, be set up in parallel diameter not
With multiple capillaries as refrigeration decompressor 63 and make cooling agent inflow the less capillary of diameter method.If this
Sample reduces the amount for flowing into the refrigeration cooling agent of cooler 61, then refrigeration is risen with the temperature of cooler 61, in refrigerating space
The temperature of the cold air of circulation rises.
Adding control 2 is：Compared with the design temperature in refrigeration cooling when beyond defrosting pattern, control unit 12, which improves, to swash
The control of design temperature in the upper strata container 24 of cold house 23.Control unit 12 can not direct controlled chilling room 23 upper strata container
In the case of design temperature in 24, the design temperature of the other positions in refrigerating chamber 20 can be improved, is swashed so as to improve indirectly
Design temperature in the upper strata container 24 of cold house 23.
Adding control 3 is：Control unit 12 reduce be provided with the space of defrosting room (in the upper strata container 24 of shock chamber 23) with
Outer space that is, the control of the design temperature of reefer space.In the control, it is preferable that the design temperature for reducing reefer space is 1
More than DEG C.Give an example：The design temperature of reefer space when making beyond defrosting pattern is -20~-18 DEG C of situation
Under, the design temperature that control unit 12 makes to add reefer space when controlling 3 is -23~-21 DEG C.If reduce setting for reefer space
Constant temperature degree, then it is controlled, is spent compared with the cooling of refrigerating space in the cooling of reefer space longer using control unit 12
Time, therefore, as a result, the temperature of refrigerating space rises, and the temperature of defrosting room rises.
In defrosting pattern as above, even if refrigerating-chamber door sensor 15a, 15b are detected：It is internally provided with defrosting room
Refrigerating chamber door that is, refrigerating-chamber door 25a or 25b open, control unit 12 also makes refrigeration Air Blast fan 62 continue to rotate.By
