Q:How much is the price of GREE 3P air conditioning copper tube? Is it expensive?
I don't know. Do you mean the extension pipe or the original connection tube?According to the official GREE charge price guide 3P Guiji extension tube at 130 yuan / m, plus 10 yuan on the basis of frequency conversion machine. This is only a guide price, which can be negotiated after sale.If it is the original machine connection tube, the reference price is 240 yuan / set
Q:What's the function of the copper pipe in the air conditioner?
It is used to transfer the refrigerant pipe, copper pipe generally wrapped foam insulation pipe, copper pipe if you are exposed, will affect the cooling effect, but also exacerbate the aging, should go to buy some heat in general, there is a hardware store. Outside the machine, it is better to have a sun block rain ceiling, or you put things up, exposure to rain as the aging, especially the heat sink, affect the cooling effect.
Q:How do you calculate the length of the refrigerator evaporator when you replace the refrigerator evaporator?
The process of open tube, high pressure pipe is connected with a pressure meter is connected with one end of the capillary, dry filter, the other end is not welded, start the compressor, if the steady pressure gauge at about 0.98-----1.177Mpa, can be considered appropriate, the pressure is too high to cut a little pressure, hour plus a short trial, until the appropriate date, then the capillary and an evaporator connected. Then vacuum pumping and filling refrigerant.
Q:Air conditioning on a thick and thin, two copper tubes play what role?
A thin high pressure pipe; a thick low-pressure pipe; used from an outside machine to an internal machine for circulating refrigerant
Q:How do you solder copper and iron? I always weld copper pipes and 3mm thick steel plates. What's the problem?
2, WE46 is used to replace the high silver wire to solve welding, Monel, copper, carbon steel, stainless steel, and the metal dissimilar welding, flame welding
Q:Can the air conditioner copper pipe fold repeatedly?
It can't be used on the air conditioning system;Because the folding and then straight, the folding will appear more serious necking, affecting the air-conditioning effect, and very unsafe.
Q:What is the ratio of the capillary and copper tube in the fridge and freezer?
Horizontal freezer with a diameter of 8mm copper tube coil in general, from the mouth of 5-6cm refrigerator dish in the first circle, and then by ring down plate, each ring spacing of 7cm, about 10cm from the bottom end. The coil is connected to the top of the capillary, the bottom corner opening is connected with the compressor inlet. The coil should be smooth, turn to be accurate, appropriate length of the two parts the card will be fixed on the aluminum coil clamp fixed on the inner wall of refrigerator, without width.The length of the coil: measurement of horizontal freezer freezer wall in a circle circumference; the depth of upper vacated 5CM, at the bottom of the rest of the vacated 10CM, according to the depth of every 7CM disc in a circle, the circle number required coil plus 1 ring (the first circle); the total length of the coil is finally on the perimeter. As measured. The freezer is 1.6 meters, depth of 50 cm.Formula: total length m= (/m-0.15m / 0.07m+ refrigerator freezer depth) /m X - /m perimeter perimeterFor example: the total length of m= (0.5m-0.15m), 0.07m+1.6m X1.6m=10.56mCapillary, no matter how long it is outside the original box, keep the original length, and then the 1.2-1.5m (the length that was buried in the box) is the same as the capillary tube of the specificationThrough the capillary clings to the bottom from the upper angle into the first ring (tube hole should be close to the corner, wearing at the bottom of the capillary and the return pipe are from hole piercing). Such as refrigerated dual-purpose freezer, frozen capillary advanced tube.Compared with the vertical coil pipe has three sideways point: 1, do not waste the corner (not accounted for) refrigerator space; 2, no accumulation of condensed water, so as to avoid the wall decay; 3, running or stopping after the initial boot can effectively avoid liquid hammer compressor.Fast method of self-made refrigerator evaporator and capillary tube!
Q:What's the brake hose for the car? Where is it installed? solve
You go to the garage to ask, otherwise, the wrong installation is not good
Q:What does the brass standard "TP2M" mean? Can anyone tell me? Thank you!
TP2 - Chinese named "2# phosphorus deoxidized copper, copper containing national standard is 99.90%, but in the process of melting with about 0.015% of the phosphorus, the main purpose is to improve the performance of pipe welding, welding mainly used for air conditioning products.
Q:The heat is too hot in the copper coated with thermal grease?
No, in order to fill the gap thermal grease is two when the contact so that the heat is rapidly conducted, while you are in the heat pipe coated with silicone grease, not only to the cooling effect but counterproductive, pure copper is too hot you can only strengthen the ventilation can play a role in cooling.
