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, and variable frequency adjustment device can be by the 50Hz of input
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.
The utility model has an advantageous effect in that：
The Cord blood case with energy-saving and frequency-variable technology that the utility model is provided, by control unit by controlling frequency conversion
Adjuster changes the working frequency of high-temperature level compressor, low-temperature level compressor and condensation fan, realizes high-temperature level compressor, low
Run after warm level compressor and condensation fan frequency conversion, improve operational efficiency after the operating efficiency of Cord blood case, frequency conversion and lifted
30%, 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.
Embodiment
The utility model 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 sent out provided with insulation
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
Can be 60Hz rate-adaptive pacemakers by the 50Hz frequency conversions of input.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 Cord blood case with energy-saving and frequency-variable technology is substantially：
Master controller in the normal power supply for 220V, 50Hz, control unit judges whether Cord blood case needs frequency conversion
Adjuster works, if it is not required, then control unit control variable frequency adjustment device is 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 50Hz frequency according to demand
Lower normal operation；Export if it is required, then 220V, 50Hz are transformed into 220V, 60Hz by variable frequency adjustment device and give cascade refrigeration unit,
High-temperature level compressor in cascade refrigeration unit is by variable frequency starting after system diagnostics non-fault mode, and blower fan frequency conversion simultaneously is opened
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 the overall VFC of refrigeration system.
The operating efficiency of the Cord blood case is high, operational efficiency lifting 30% after frequency conversion, power consumption reduction by 16%.
Certainly, described above is not that, to limitation of the present utility model, the utility model is also not limited to the example above,
The variations, modifications, additions or substitutions that those skilled in the art are made in essential scope of the present utility model, also should
Belong to protection domain of the present utility model.
