  SEMI-HERMETIC COMPRESSOR
 
   
Coolant System expressed intentions Semi-closed compression machine constructed
* Motor and compressor installed in the chassis with a semi-closed
* Speed of 1450 changed, and / pm Closed for 2900
* switch from motor cooling air or refrigerant
* apply to commercial and industrial adverse work environment
* / pm design life of 15-20 years
Refrigeration system four components : 1. Compressor 2. 3 condenser. EXV 4. Evaporator refrigerant three states : 1. 2 overheated gas. saturated vapor-liquid mixtures 3. supercooled liquid
Blotch semi-machine should cut down the scope
Medium and high-temperature applications : -30~5 ≧
 Cryogenic applications : -45 -20 ＜ C ~
Note : condensing temperature of 45 ＜ C and above, need additional cylinder head cooling fans, air flow for 10 M3 / min. If the compressor installed in the air-cooled condenser, can not.
Blotch compression engine with scope

* Largest compression ratio : 15
* maximum pressure : the greatest return to stagnation
* superheat steam :
* 30 ＜ C maximum exhaust temperature : 135 ＜ C (exhaust pipe surface)
* crankcase maximum temperature : 80 ＜ C
* Motor Temperature : 120 ＜ C
* Allow the use of electrical voltage : Rated three-phase voltage of ＼ 10%
* compressor allows the maximum working pressure : high pressure side of 2.4MPa.
* Low-voltage side of 0.5MPa temperature : 5 ＜ C ~ 40 ＜ C
