OK.Now let us start our this discussion how to build a standard & perfect cold room.
 

1.Installation
 

(1)Refer to technical parameters for installation dimensions and connections.
 

(2)The unit must be installed horizontally while the inclination of the table to be mounted on shall be less than 5℃.
 

(3)The connections must be done in accordance with the requirements.
 

(4)Tubing of the suction pipe:
The part of the horizontal suction pipe towards the refrigerant flowing direction shall have a inclination of 0.5% (5mm/1m).The section of the pipe must guarantee a minimal speed of the finally acquired air at 4m/s. In the vertical pipe, there must have a speed between 8-12 m/s to guarantee a correct back oil. At each foot of the vertical pipes, there must have a U-shape elbow, while the length of each U-shape elbow must be as short as possible to avoid accumulating too much oil.
 

(5)Charging refrigerant and cooling oil

A:Charging refrigerant 
Normally charge refrigerant in liquid form from the multi-purpose passage of liquid feeding shut-off valve of the liquid storage tank, it is forbidden to charge refrigerant in liquid form from the suction port. After making vacuum of the system, the initial charging should be 1/3 of the liquid storage tank, then run the compressor and recharge it to the set amount, however no more than 70% of the capacity of the liquid storage tank.
 

B:Replenishing cooling oil
When the cooling system is running, part of cooling oil has gone along with the refrigerant to the pipe system and the oil level is declining, so the cooling oil should be replenished in time, while the amount of replenishment depends on the length of pipe.
