Mouthful.
In embodiment, referring to shown in Fig. 2 and Fig. 3, the lower area in refrigerator room is arranged in refrigeration wind turbine, by cold
It hides wind turbine and carries out air draught, in other words, by the way of the air draught of lower part.Circulated air by refrigerate air duct both sides blow upwards, and with refrigeration
Evaporator such as tube-in-sheet evaporator carries out heat exchange.A part of cold is sent by the second air outlet of refrigerating chamber to refrigerating chamber,
Cold diffuses to refrigerating chamber lower area from refrigerating chamber upper area；Remaining cold by refrigerate air duct middle and lower part the first air outlet
It send to ice greenhouse.In turn, it so recycles again by the refrigeration wind turbine return air of lower part after Cooling capacity exchanging, realizes refrigeration.Wherein, cold
It can also be centrifugal blower that Tibetan wind turbine, which can be axial flow blower,.It in some embodiments, can be by the temperature-varying zone of refrigerator such as three
Warm area is referred to as ice greenhouse, for example, the temperature range of ice greenhouse is at -3 DEG C -3 DEG C.
By the way of the air draught of lower part so that the cold in refrigeration air duct is delivered up, so as to avoid refrigeration from draining
Temperature is too low and generate risk of icing at slot, without opening refrigeration compensating heater, reduces power consumption, saves electric energy.
The lower part air draft structure of refrigerator based on above example, as shown in figure 4, the temperature controlling party of the embodiment of the present invention
Method includes：
The temperature of ice greenhouse after S1, acquisition compressor shutdown.
As shown in figure 3, temperature sensor can be arranged in ice greenhouse, to detect the temperature of ice greenhouse.
Normally, each warm area of refrigerator sets different temperatures, when warm area temperature reaches set temperature, is then not necessarily to system
It is cold, compressor shutdown, the compressor operating if set temperature is not achieved in warm area temperature, i.e., in the process of refrigerastion of refrigerator, pressure
Contracting machine needs continuous start and stop to ensure allowable range of the temperature in set temperature of warm area.
In an embodiment of the present invention, refrigerator room includes refrigerating chamber and ice greenhouse, is stopped if the temperature of refrigerating chamber reaches
Machine point temperature, compressor are shut down, often so that set temperature is not achieved in the temperature of ice greenhouse.In order to balance refrigerating chamber and ice

Row, so that ice greenhouse first reaches shutdown temperature point.
S2 refrigerates wind when adjusting compressor start next time according to the default shutdown temperature of the temperature of ice greenhouse and ice greenhouse
The rotating speed of machine.
Specifically, it is different to refrigerate exchange rate of the rotating speed difference of wind turbine then between compartment and refrigeration evaporator, refrigerates
The more high then air circulation of rotation speed of fan is bigger, and indoor temperature reducing rate is faster；Conversely, refrigeration wind turbine rotating speed more it is low then
Air circulation is smaller, and indoor temperature reduces relatively slower.In an embodiment of the present invention, ice greenhouse is under refrigerating chamber
Side, by the way of the air draught of refrigerator room lower part, circulated air trend for from bottom to top, thus, the cold that ice greenhouse receives is more than
Refrigerating chamber, but the temperature of refrigerating chamber is less than ice greenhouse, in order to balance the temperature control of the two, the embodiment of the present invention passes through adjusting
The rotating speed of wind turbine is refrigerated to realize.
In some embodiments, acquire compressor shutdown after ice greenhouse temperature, if the temperature of ice greenhouse be more than ice temperature
The default shutdown temperature of room, it is believed that current cold is quickly reduced insufficient for the temperature of ice greenhouse, and the temperature of refrigerating chamber reaches
Shutdown temperature point has been arrived, and set temperature is also not achieved in the temperature of ice greenhouse, causes the cool storage area temperature difference bigger than normal, then presses next time
Contracting machine start when refrigeration wind turbine rotating speed improve gear, to improve ice greenhouse at a temperature of reduction of speed rate.If next compressor stops
After machine, the temperature of ice greenhouse is still not able to reach set temperature, then improves the rotating speed gear of refrigeration wind turbine again, successively class
It pushes away, so that the temperature of ice greenhouse reaches default shutdown temperature prior to the temperature of refrigerating chamber, at this point, refrigerating chamber and ice greenhouse
To reach set temperature, avoid the cool storage area temperature difference bigger than normal.
Alternatively, if the temperature of the ice greenhouse after compressor shutdown is less than the default shutdown temperature of ice greenhouse, it is believed that ice temperature
The Cooling capacity exchanging rate of room is too fast, in order to avoid at rhone freeze or with the temperature difference of set temperature it is bigger than normal, then press next time
The rotating speed of refrigeration wind turbine reduces gear when contracting machine starts, similarly, if the temperature of ice greenhouse is still less than pre- after shutting down again
If shutdown temperature, then the rotating speed of refrigeration wind turbine is reduced again, and so on, so that temperature of the temperature of ice greenhouse prior to refrigerating chamber
Degree reaches default shutdown temperature and avoids temperature reduction is too fast from causing the temperature difference bigger than normal or freeze.
Alternatively, if the temperature of ice greenhouse is equal to the default shutdown temperature of ice greenhouse, illustrate that the temperature in ice greenhouse reaches
Compressor shutdown when default shutdown temperature, at this point, ice greenhouse and refrigerating chamber can reach set temperature, and it is inclined with set temperature
It is poor less, then next time compressor start when maintain the rotating speed of refrigeration wind turbine constant.
As an example, during compressor operating, the operation control for refrigerating wind turbine is set as following several modes：1, rotating speed
For 2300rpm, i.e. working voltage is 11.5V, this is maximum speed gear；2, rotating speed 2200rpm, i.e. working voltage are
10.5V；3, rotating speed 2100rpm, working voltage 9.5V；4, rotating speed 2000rpm, i.e. working voltage are 8.5V；5, rotating speed
For 1900rpm, working voltage 7.5V, this is minimum speed gear.
As shown in figure 5, for according to the stream of the temprature control method of the refrigerator ice greenhouse of the specific embodiment of the present invention
Cheng Tu is specifically included：
S100, compressor shutdown.
For example, set current environmental temperature as 32 DEG C, refrigeration wind turbine first carries out the operation of 7.5V rotating speeds when compressor start, when
When the temperature of refrigerating chamber reaches shutdown temperature point, compressor shutdown.
S110 detects the temperature of ice greenhouse.
S120 compares the temperature Tv and default shutdown temperature Tvt of ice greenhouse.
S130 meets Tv>Tvt then enters step S140.
S140 refrigerates wind turbine upshift operation in compressor start next time, for example, refrigeration wind turbine executes shift mode extremely
8.5V operation.In turn, when meeting halt condition, compressor shutdown, that is, return to step S100.
S150 meets Tv<Tvt then enters step S160.
S160 refrigerates wind turbine downshift operation in compressor start next time.In turn, when meeting halt condition, compression
It is return to step S100 that machine, which is shut down,.
S170 meets Tv=Tvt, then enters step S180.
S180 refrigerates wind turbine in compressor start next time and keeps existing running speed.In turn, meeting halt condition
When, compressor shutdown, that is, return to step S100.
S190, compressor is switched to booting from shutdown status when meeting compressor start up condition.
It is recycled according to the above process, until ice greenhouse first reaches default shutdown temperature, to ensure refrigerating chamber and ice greenhouse
Temperature is attained by set temperature, realizes and controls the temperature of ice greenhouse.Wherein, permit if the rotating speed of refrigeration wind turbine reaches highest
Perhaps gear, then next time compressor start when refrigeration wind turbine rotating speed maintain highest allow gear.It is cold during compressor shutdown
Corresponding rotating speed operation when last compressor open state can be executed by hiding wind turbine.
Generally speaking, the temprature control method of the refrigerator ice greenhouse of the embodiment of the present invention is existed based on that will refrigerate wind turbine setting
The design of the lower part of refrigerator room, using lower part air draught scheme, refrigerator complete machine cost Continuous optimization improves productivity effect, compares
It in using top air draught scheme, can effectively solve the problems, such as that ice is stifled at drainpipe, be reduced without opening refrigeration compensating heater
Electric energy consumption；Also, compressor start next time is determined according to the temperature of ice greenhouse after compressor shutdown and default shutdown temperature
When the rotating speed of refrigeration wind turbine realize the control to ice greenhouse temperature to adjust air force, ensure that refrigerating chamber and ice greenhouse are equal
Set temperature can be reached, and be unlikely to temperature to reduce too fast and rhone is caused to freeze.
