Thermal expansion pneumatic valve installation requirements

. Check it before the installation, particularly thermal parts;
. Installation position, it must be near the evaporator, pneumatic valve should be installed vertically, not tilted or inverted installation;
. Should be paid attention to when installation, make the fluid inside the heat organization always stay within the heat pack, so thermal bag should be lower than pneumatic valve is installed;
. Thermal package installed in the evaporator export levels as much as possible back to the trachea, the general should be far away from the compressor suction mouth. M above;
. Thermal package must not be placed in a fluid from tube road;
. If the evaporator export with gas-liquid exchanger, the heat are packaging, on the evaporator outlet before the heat exchanger;
. Thermal package is usually placed on the evaporator muffler, and clingy wall bandage tightly, contact point scale should be clean, bared metal color;
. When the pipe diameter less than mm, thermal bag can be tied in the back to the top of the trachea; When mm in diameter, can be tied in the back to the underside of the trachea °, to prevent the pipe at the bottom of the product oil etc, affect the correct thermal heat packs.
