Cold storage contents are:

     Cold storage facilities of various engineering equipment supplies materials procurement , libraries Installation , inside and outside the machine lifting, laying the connecting pipe , pipe insulation, drainage installation, wiring connections set up , the control system is installed , inside and outside the machine power cord connection and system debugging . Cold storage units required cable into the power supply that is not included in the scope of the installation , cold storage and base units with by the civil and construction , we are responsible for the distribution parameters and provide the relevant drawings .

Cold storage installation points and technical requirements :

Because the system piping and drainage requirements and needs through the body wall library should be approved should open hole location and size , the correct size hole marked the opening play of the hole on the wall , the wall perforation must levy the field of civil engineering and technical personnel have no effect on the structure of the building advice to go after perforating operations. Pipeline over hole in the wall , using the hammer perforation. If unfit hammer perforated rear wall can be used with the approval of the owners agree otherwise perforation. The size of the hole in order to be able to pass through the pipeline ( including insulation ) prevail through the wall of the pipeline should be set steel casing , tubing welds shall not be placed within the casing, galvanized iron casing should be level with the wall or floor Sarkozy , but it should be higher than the ground at least 20mm, pipe insulation and casing gap applications or other non-combustible material filling shall not be used as a support casing pipe .

Refrigerant piping :
 
     ( 1 ) Step : by drawing pipe welding → ​​→ → pipeline laying Blow drying → → → insulation leak
     ( 2 ) should strictly observe the principles of refrigerant piping piping three principles: a dry , clean and airtight . The first is the prohibition of dried water into the copper tube installed in the front , followed by the pipe to purge and vacuum drying .

    Units installed outside the library :

( 1 ) out of the box outside the library unit equipment inspection , inspection equipment unpacking inspection record sheet to fill ;
   
    ( 2 ) outside the library unit handling and lifting equipment ;

( 3 ) the unit holder on the roof outside the library foundation ( civil tie ) on the base unit and the use of foot or bracket . Between the library and the library machine outside the machine , technical regulations between the outdoor unit should be associated with the building to do .

     Tightness test :

( 1 ) order of operations : refrigerant piping completion time control → → → pressurized nitrogen pressure → pass inspection
 
    ( 2 ) testing personnel organization and division of labor.

( 3 ) essentials : refrigerant pipe pressurized with dry nitrogen is required , slowly pressor test :
