Household air conditioning cooling agent and machine outside or inside the machine, on her part
Outside the machine, thick brass valve..Want, but you still don't add.
Outside the machine, and the machine has a refrigeration of the valve
First prepared a set of hex wrench and 14, 17 open end wrench and your freon. General air conditioning cooling agent is freon, we from the join outdoor, outdoor parts have 2 copper pipe, a stout a thin, we put the coarse and fine brass T open the cover of junction, lock hexagonal screw with hex wrench, and then put the freon containers interface to the thin tube, open the screw into the thin tube, observe the pressure, after full charged thin tube lock screw, then it is fine to collect pipes, screw down the screws, open the hexagon screws, cover nut. Suggest you won't find fix up to about 200 pieces
On the refrigerant from the large outdoor cut-off valve needle valve to join in the system. As the supplying operation steps are as follows: 1, to open on air conditioning refrigeration mode or forced cooling mode; , composite low pressure table connection pipe joint of pressure refrigerant tank needle valve opening, the middle one root tube needle valve on the air conditioner outdoor low-voltage cut-off valve; 3, low pressure cut-off valve needle valve hose interface is not tight, first open the refrigerant tank valve, open a small open degree of composite pressure low pressure table valve; 4, for low pressure cut-off valve needle valve connection with white mist coolant jet quickly shut down low pressure table corresponding to the valve and screw down the low-pressure valve hose interface; 5, refrigerant tank is put on the electronic scale weighing control or for the amount of refrigerant is measured with a thermometer with discharge temperature of compressor suction, compressor running current is measured with pliers flow table, according to the operation parameters to control the refrigerant filling quantity; 6, refrigerant charging before step 1, 2, 3, 4 is the process of the air inside discharge hose, is very important, must discharge clean air; 7, cold media should be in the form of "gas" filling into the pipe line of air conditioning system, in order to avoid too much liquid refrigerant compressor in liquid strike.
