【 Weak current College 】 Tri air conditioning installation seven

<br> <br> There is a window type air conditioner and split into two types. Install camion, technology requirements, technical points, labor-intensive. There is a popular Word installed industry: "one-seventh of the installation of air conditioning .. "Mean air conditioner use effect is good or bad, and installation of quality has a lot to do. On the whole, split air conditioner installation has several links to any step in the action, will affect the effectiveness of the use of air conditioners .and life. <br> Indoor machine should be installed in a solid wall. Select the installation location of indoor unit, in addition to the need to respect the user views, indoor unit installation should fully consider the location and layout of the room air- .conditioning, air distribution, smooth. Also making it blow out of the air conditioning can sent to every corner of the room, the room can form reasonable air convection. Indoor installation location near cannot have heat source, and the distance should be greater than Windows .and doors to prevent air loss 0.6m too large; its installation height should be greater than, less than 2.2m 1.8m. <br> Air conditioner in the outdoor unit should not be occupied public sidewalk along the road on both sides of the building .to install air conditioner installed frame bottom (installation frame does not affect public channel according to the level of the installation of) the distance from the ground shall be greater than 2.5m. And the opposite wall distance should be 2 meters above the sea level to .avoid air conditioning cooling-performing lead to overload the machine. External machine installation location should be convenient for maintenance, the machine should be level. At present, the general air conditioner factory provides refrigeration piping length is 3-4m, if there are no special .needs best not threaded. So, determine the indoor installation location when you have to consider it and the outdoor unit of piping connections should be appropriate and reasonable, to reduce the pipe bending, in favor of refrigerant flow unobstructed, condensate drain can also be smoothly ., and to subsequent maintenance is left a certain space. <br> Outdoor installation location to be chosen in a well-ventilated place, convenient maintenance. Do not install on the balcony, it is not good for ventilation, cooling capacity will be reduced by .30 per cent, and even from ventilation short-circuit Burnout compressor. Outdoor unit weight is large, so pay special attention to a solid wall, now have air conditioners fall injury accident cases, if mounted on the outside terrace, you should use a pass .through the bolt to the inside of the wall, and with the flat iron la lining to increase strength. Specifically, outdoor installation requirements: from the ground level is greater than 2.5m, and indoor height difference should be less than 12m (in air conditioner .installation specifications as standard), and the distance between adjacent doors and Windows is 3 ~ 4m. Indoor unit is hanging plate fixed on the wall. Installation, the first hanging Board level on the wall, in order to allow the condensation water can smooth out ., the outlet side of the lower 2.0mm, but if the tilt over 5.0mm will affect the overall appearance. As shown in Figure 2, the first gaizhui wall paint hanging plate fixed with 4 screws nail. Common fixation method is used to impact drill .out of four walls of the hole, then into the plastic plugs or Cork to Rotary screw. You can also use according to the wall of concrete nail or fluxes yarns fixed hanging plate. Hanging plate an good hands firmly down after, check the installation is .strong, hanging plate should be able to withstand 20kg weight. Indoor and outdoor machine connection line, wire to pass through, so before installing outdoor unit must be called wall holes. In order to facilitate the smooth flow out of the condensate water, over the .wall holes General and indoor unit out of the tube balanced or slightly lower. In order to maintain a strong and beautiful wall, professional installer will use the "diamond" drilling. Hole punch, to observe the understanding within the walls drilling location is buried wire ., whether or not reinforced Widget, that caused the accident, or drilling difficulties. From indoor to outdoor drilling, water drilling to elevation 5 degrees, play good over the wall holes in high low, easy to condensed water, rain water cannot flow into the .room. <br> Water the drill hole punch to master the cooling water water water injection, note too large, the water will spatter along the walls are brick mortar around the dirt is difficult to clean after; note the water is too small, easily .burned bits. Fit is a note into bits of water, which was produced by thermal evaporation of bit and wall absorption, which gradually acquired in practice. Drilling is not drilling Ning slow, if bit jitter, hands hold on to for a bit. Air .conditioner installation frame load capacity should not be less than air conditioner unit weight of 4 times, outdoor unit installation frame carrying capacity at least 180KG. Air-conditioner material should not be in a loose mounting surfaces (such as legacy brick walls, brick wall housing ., etc.) for wall installation; the installation conditions shall be in the wall installation should fully consider the installation of material strength and load bearing tolerance and the same mounting surfaces installed air conditioning factors such as the number and, if necessary, reinforcing or protective .measures taken to ensure the safe operation of the air conditioner and personal security. <br> Air conditioner is installed, the installation and the installation frame, installation bracket and the connection between the unit should be firm, stable, reliable, and ensure that the .air conditioner after installation without slippage, tipping or falling. <br> Split air-conditioner is installed on a dedicated stand. First assembled brackets, in the outdoor unit base two mounting holes horizontal distance, in the chosen location, expansion bolts into the wall .. Supports 6 dual diameter 8mm above expansion bolts fastening in load-bearing walls, after the last nut may be loose or glider phenomenon on the bolts and tighten a "spring mat". Check the support level is weak, the outdoor unit on a safety .rope, two cooperation will it move out of place. Outdoor unit moving tilt should not be greater than 45 degrees, and be careful not to touch the bad things on the prominent stop valve. In the absence of prior to installation, do not remove the .stop valve protection CAP, dust dirt into one line, refrigeration system failure. <br> Outdoor machine on the second floor above installed, the installer must be fastened, and note the outdoor unit the following cannot be someone pass, stranded. Use tools ( .like a wrench), best bolt rope or wrist, to avoid accidentally falling, caused the accident. <br> This link is to connect internal and external unit. Need for binding of pipe or wire are: straight rough copper tube known as the low .pressure pipe, thin copper tube called a low-pressure fluid pipe, another is plastic hose and outlet. Control cable, including power and signal cables. First floor, with both hands to low pressure pipe and tube low pressure liquid respectively "straight", .and the two pipes on the respective package manufacturers to provide heat insulation materials. And then, then put them and outlet pipe, control cable with plasticBinding Strip. <br> Lashing from outdoor client trumpet 10cm to indoor unit, so tying the rain not easily .into the insulation jacket, fastening and do not push too large to avoid outlet pressure flat. All pipeline fastening and, through the wall of the hole is not pipeline protection bolts to remove to prevent dust, moisture, dirt into the copper pipe, causing failure .. <br> Some installer to low pressure pipe and Tube bundle in low pressure liquid a thermal insulation sleeve, this is inappropriate. Because the two pipe insulation sleeve will produce heat, cooling capacity, easy burnt compressor. <br> This is the key .to an air conditioner installed. Connection before you carefully check the copper tube ends of the trumpet is intact, there should be no deformation and cracking. Before connecting the indoor unit, loosen indoor piping on the nuts should be heard within the nitrogen released "zi .". If you do not have to release the nitrogen, indicates that indoor leakage points cannot be used. (Currently, the part of the air conditioning did not nitrogen protection) indoor tubing and pipe connection methods are shown in Figure 4. Connection time you .must first hand brass conical nut screwed pipe thread, and then use torque wrench, tighten the nut until wrench "night Tower". For diameter 6mm copper tube, wrench torque should be 18 Newton · m; <br> On the copper tubes with a .diameter of 9mm should be 40 Newton · m; diameter 12mm copper tube should be 52 Newton · m. Never in the nut sheath does not align "recognition for" when using a wrench, tighten the nut that reckless approach would cause serious damage to the .spout, once the thread out, only scrap, expanding again. <br> No torque wrench, can only be used with open end wrench (or wrench) to tighten the nut, this will experience mastering the size of the strained, the installer must .clearly realize that force is too large, too small are harmful, mastering pipe connections of tightening efforts, is the key to successfully install air conditioner. <br> Connecting pipe through the wall of the hole, according to the installation location for outdoor unit, .the extra lines to one side of the wall. Line too long, you can use both hands to coiled around a diameter 60cm ring, and wire it up at the outdoor unit bracket to prevent wind is fro. If the pipe is not coiled loop, .you can bend into u-shaped, prevent rain water flow along the pipeline to the mother outdoor phone lock. <br> After adjustment, the entire line to be pretty nice. First hand a good low-lock the trachea and wrench to 40 Newton .· m torque tightened. Then hand good low liquid pipe lock and wrench in 18 Newton · m torque tightened. Low pressure liquid pipe thinner, easy to adjust. Air conditioner control cables in random directions that came with the factory will be detailed in the statement ., if the installed air conditioning model inexperienced, must be repeated to confirm that no mistake then. General first control line of indoor termination, then the online client and outdoor machine wiring board do a tag in which these connections. Figure 5 is a species of .air-conditioner's connection method. Add good wire head exposed parts must not be too long, cannot reveal the serrations. Copper wire and terminal's contact area as far as possible, and to be solid and reliable. Otherwise the thread connection, can cause fever, .loose contact ablation, even causing a fire. Wire connection is not strong, but also damage control circuits, <br> The final evacuation. commissioning leak. <br> <br> <br> <br>.
