Limitation that is costly in frequency-changeable compressor or being used due to technology, temporary transient no frequency-changeable compressor can be applied to be protected in low temperature
Case field is deposited, so forcing us by changing thinking, is innovated on the basis of existing, conversion frequency enhancing refrigeration performance is carried
High workload efficiency reaches the purpose of energy saving.
The content of the invention
Do not possess the problem of converter technique for existing Cord blood case, there is energy-saving and frequency-variable the invention provides one kind
The Cord blood case of technology, improves the operating efficiency of Cord blood case.
The present invention uses following technical scheme：
A kind of Cord blood case with energy-saving and frequency-variable technology, including casing, be provided with casing cascade refrigeration unit and
Control unit, cascade refrigeration unit includes invariable frequency compressor and condensation fan, and frequency conversion part, frequency conversion are additionally provided with the casing
Part is connected with cascade refrigeration unit and control unit respectively, and control unit is connected with cascade refrigeration unit, the frequency conversion part
Including variable frequency adjustment device, variable frequency adjustment device is connected with invariable frequency compressor and condensation fan respectively, and control unit is by controlling frequency conversion
Adjuster changes the working frequency of invariable frequency compressor and condensation fan.
Preferably, the variable frequency adjustment device is arranged on the end of invariable frequency compressor, the 50Hz that variable frequency adjustment device will can be input into
Frequency conversion is 60Hz rate-adaptive pacemakers.
Preferably, the invariable frequency compressor includes high-temperature level compressor and low-temperature level compressor.
Preferably, the control unit includes temperature controller, and temperature controller passes through Control cascade refrigeration unit operation.
Preferably, the inside of the casing is provided with thermal insulation foaming layer.
The invention has the advantages that：
The Cord blood case with energy-saving and frequency-variable technology that the present invention is provided, by control unit by controlling variable frequency adjustment
Device changes the working frequency of high-temperature level compressor, low-temperature level compressor and condensation fan, realizes high-temperature level compressor, low-temperature level
Run after compressor and condensation fan frequency conversion, improve the operating efficiency of Cord blood case, operational efficiency lifting 30% after frequency conversion,
Power consumption reduction by 16%.
Brief description of the drawings
Fig. 1 is a kind of structure principle chart of the Cord blood case with energy-saving and frequency-variable technology.
Specific embodiment
The present invention is specifically described below in conjunction with the accompanying drawings：
With reference to Fig. 1, a kind of Cord blood case with energy-saving and frequency-variable technology, including casing, box house are provided with insulation hair
Alveolar layer.
Control unit 1, frequency conversion part 2 and cascade refrigeration unit 3 are provided with casing, cascade refrigeration unit 3 includes fixed frequency
Compressor and condensation fan, invariable frequency compressor include also may be used in high-temperature level compressor and low-temperature level compressor, cascade refrigeration unit
To use single invariable frequency compressor.Frequency conversion part is connected with cascade refrigeration unit and control unit respectively, control unit and overlapping
Refrigeration unit is connected.Frequency part includes variable frequency adjustment device, and variable frequency adjustment device is arranged on the end of invariable frequency compressor, variable frequency adjustment device
The 50Hz frequency conversions that will can be input into are 60Hz rate-adaptive pacemakers.Variable frequency adjustment device compresses with high-temperature level compressor, low-temperature level respectively
Machine is connected with condensation fan, control unit changed by controlling variable frequency adjustment device high-temperature level compressor, low-temperature level compressor and
The working frequency of condensation fan.
Control unit includes master controller, and master controller passes through Control cascade refrigeration unit operation.
The course of work of the Cord blood case with energy-saving and frequency-variable technology is substantially：

Adjuster works, if it is not required, then control unit control variable frequency adjustment device does not run, master controller directly passes through relay control
Cascade refrigeration unit operation processed, high-temperature level compressor, low-temperature level compressor and condensation fan are in the frequency of 50Hz according to demand
Lower normal operation；If it is required, then 220V, 50Hz are transformed into 220V, 60Hz by variable frequency adjustment device and are exported and is given cascade refrigeration unit,
High-temperature level compressor in cascade refrigeration unit by variable frequency starting after system diagnostics non-fault mode, open by blower fan frequency conversion simultaneously
It is dynamic, realize that high efficiency is freezed, after system detectio reaches entry condition to low-temperature level compressor, low-temperature level compressor variable frequency is opened
It is dynamic, realize to refrigeration system entirety VFC.
The high working efficiency of the Cord blood case, operational efficiency lifting 30% after frequency conversion, power consumption reduction by 16%.
Certainly, described above is not limitation of the present invention, and the present invention is also not limited to the example above, this technology neck
Change, remodeling, addition or replacement that the technical staff in domain is made in essential scope of the invention, should also belong to of the invention
Protection domain.
