Actual effect compares:
Circular water treating system of the present invention is implemented on a freezer, and this freezer is provided with the compressor and the cooling tower system of several different types, and situation is as follows:
1. second mansion liquefied gas compressor
2. two, five, three and No. four compressors of second mansion
3. two and single-stage ammonia compressors of first mansion
Above various types of compact machine has nothing in common with each other, and function situation separately also each is variant.
Correlation data is as follows:
1. second mansion liquefied gas compressor
Insert do not install before the native system and native system is installed after all data in identical month, and make to draw a conclusion:
Classification Before not installing After the installation
Average load 37％ 27％
The standard deviation of load 6％ 10％
Total power consumption 24,019.8 degree 16,609.8 degree
Per hour operate average power consumption Per hour 33.268 spend Per hour 29.873 spend
Per hour percentage is saved in running - 10％
The standard deviation of load shows that bigger variation of load is arranged after the installation, expression, and in the goods and materials turnover, installing will have relatively large goods and materials to deposit in before installing the year after next.Yet total power consumption has lacked 30%, and compressor per hour operates average power consumption and lacked 10%.
2. two, five, three and No. four compressors of second mansion
Insert before installing and the raw data in installation identical month of back, and make to draw a conclusion:

Total running hours 1426 1360 690 990
In four compressors, have three average load and standard deviation quite similar, but after installation, total power consumption, average power consumption and a total running hour number average increase considerably.With install before compare, the back total power consumption is installed have been increased more than 330%.This clear expression, with install before compare, deposit the goods and materials that freeze the storehouse after the installation in and increase considerably.
Because current consumption so increases considerably, we have calculated freezing capacity with the formula that U.S. refrigeration association provides:
Efficient improves percentage=1-(install this treatment system after the preceding pressure of pressure/this treatment system of installations) γ
* in the above-mentioned formula, γ=1.65
The purpose of this kind analysis is that suction pressure and outlet pressure to relevant compressor under the roughly the same situation of maintenance load, electric power input (electric current input) and other function situation are compared.Saving percentage can conclude in the following table:
Two and No. three compressor is installed the back than the average saving rate before installing 20％
Four and No. five compressor is installed the back than the average saving rate before installing 43％
3. two and single-stage ammonia compressors of first mansion
The data analysis work of first mansion is very difficult, because in the different time of every day, running characteristic different compressors very inequality is arranged in running.This kind data analysis and being summarized as follows:
Single-stage compressor
Project Preceding 300 amperes of analyses are installed Back 300 amperes of analyses are installed
Average outlet pressure (every square centimeter of kilogram number) 11.66897 11.45362
Average suction pressure (every square centimeter of kilogram number) 1.486207 1.515217
Save percentage - 6.67％
Double-stage compressor
Double-stage compressor Preceding 200 amperes of analyses are installed Back 200 amperes of analyses are installed
Average outlet pressure (every square centimeter of kilogram number) 10.95 10.73043
Average suction pressure (every square centimeter of kilogram number) 0.511111 0.517391
Save percentage - 5.67％
Because first mansion uses evaporative condenser, therefore compares with the normal cooling tower in second mansion, it is less to save percentage.
