The freezer price - The freezer experience sharing

< p > freezers - price commercial freezer to share the experience of related knowledge and experience, we have share a lot in the article. So want to say to you today and air-conditioner is closely related to the information, that is refrigerant. Freezers used for a long time, may be because of the lack of refrigerant, and lead to inadequate refrigeration, refrigeration phenomenon or not. You will need to filling refrigerant, air-conditioner how filling refrigerant? The following freezers and prices and see it together. First is certainly need some practical training equipment: three way valve, pressure gauge, R12, R22 gas cylinders, hoses, hexagon wrench, clip-on ammeter, combination pliers, pinch-off pliers, oxygen welding equipment. With that, the next step for filling of air-conditioner. 1) connect all kinds of equipment, vacuum pressure drop to 133. 3 pa when closing the 3-way valve (pos. No. , attach a hose to be removed from the vacuum pump suction mouth, pick on R12 cylinders, loosen hose at in the three-way valve. (2) the handle on the R12 cylinders slightly open, when the refrigerant R12 spewed from loosen hose mouth quickly will loosen hose clamp on the three-way valve ( The move is to eliminate the residual air in this section of the hose) 。 (3) the R12 cylinder inversion, air-conditioner compressor power, the power cord into the clip-on ammeter. Open the three-way valve handle, make compressor suction part after the refrigerant R12 quickly shut down. Observe the pressure gauge pressure and clip-on ammeter, pressure, current decreases after open the three-way valve handle, quickly close again after filling part of the refrigerant R12 three-way valve handle, repeat several times. (4) comprehensive observation: pressure gauge pressure steady at 0. 03 - 0. 05MPa( The winter is 0. 02 - 0. 04 mpa, the summer is 0. 05 - 0. 07 MPa) 。 Clip-on ammeter running current steady at 0. 6 - 0. 8 a, condenser heat evenly, filter drier temperature slightly higher than the ambient temperature. Evaporator surface uniformly frosted, feel sticky. At this point that the refrigerant filling quantity properly, can be flat capillary pressure in the sealing pliers, reoccupy combination pliers clip capillary break, fracture with oxygen welds welded. (5) the welding place for leak detection with soap and water. Thus basically completed the refrigerant filling of air-conditioner, but it's important to note that in the process of filling refrigerant should be controlled by 3-way valve handle of the refrigerant filling quantity, every time shoulds not be too much, at the same time observe the change of pressure and running current, so that it can be better, more secure. < br / > < / p >
