Wedding dresses steps: First, the preparatory work at least two or more persons skilled refrigeration repairman, tool set, seat belts and other safety equipment. Two steps disassemble 1 Recovery of refrigerant whether it is winter or summer transfer machines, air conditioners must be collected refrigerant to the outdoor unit. Should start before disassemble the empty withered, remote set cooling, refrigeration compressor operation status to be normal, with the wrench outside the machine liquid pipe and gas pipe protection cap on the interface Xuzhou conditioning maintenance, shut down the high-pressure tube (thin) cut-off valve, l min (bigger air conditioning on the other about 2 minutes) after the appearance of condensation tube, immediately turn off the low-pressure pipe (crude) cutoff valves, with the rapid shutdown, unplug the power cord, use a wrench to tighten insurance cap, refrigerant recovery work completed so far. 2. After the demolition of interior mechanism of refrigerant recovery, removable indoor unit. The indoor unit is connected with a wrench to unscrew the lock master, ready sealed with sodium child spin cover your indoor unit connectors wire lines, prevent joint damage the wire pattern in delivery; then cross from the Line of Control. At the same time should be marked to avoid the wrong during installation. If the signal lines or power lines are wrong, it will cause outside the machine is not running, or uncontrolled machine. The machine is generally fixed peg board is strong, unloading more difficult; emptied remove siding, then gently pat into flat concrete floor flat correction. 3. Demolition of the outdoor unit split outdoor unit by professional refrigeration repairman demolished in ensuring safety. Connect twist lock away his mother, live in a prepared application sealed sodium child spin care out connectors for wire lines. Loosen the screws with a wrench outside the machine at the end of the foot. After the demolition of the outdoor unit down, preferably with rope Diaozhu unloading put balance should pay attention to avoid vibration, bump, and note the downstairs cars and people. Air-conditioned building in the summer will depend on the refrigerator interior heat load is moved outdoors. Clearly, reducing the indoor heat load, reducing the running time of the refrigerator, central air-conditioning system energy consumption is reduced. Indoor heat load from two aspects, one indoor and outdoor temperature and the heat caused by the exchange of Xuzhou air conditioning repair parts, on the other hand is the heat load generated by indoor lighting and equipment. Therefore, it can take shade, airtight, thermal insulation and other measures to reduce indoor heat load to save energy. Reduce indoor heat load (1) reduce the direct sun radiation shade roof, walls, windows and through the window into the room air-conditioning maintenance, can be cornice, visor (canopy), coated glass, etc; reduce the external walls, roof sunlight sites hot shot, can be light-colored exterior finishes, the insulation layer is disposed outside the exterior walls and roof roofing, roofing or overhead. Increased external shading for summer cooling load (or cooling capacity) reduction is very obvious. According to the China Academy of Building Research determination Xuzhou central air conditioning repair, whitewashed cement roofing, roof surface temperature in summer can be reduced 16-19 ℃. (2) gas-tight doors improve airtightness, preventing gap inlet. Using airtight steel doors not only good, but great resistance, and reduce noise and dust. Or the use of doors and windows sealed, airtight doors and windows to improve. Room air changes from 8 to 5 times, reduce the consumption of cold buildings around 8%. Therefore, the design should be well sealed doors and windows. Additional closed doors strip is an important means to improve air tightness. According to the specific circumstances of the doors and windows, using different seals. Such as rubber, plastic strips or rubber seal combination. (3) the use of insulation materials for wall insulation, roofs, doors, windows, etc. insulation, such as rock wool, slag wool, glass wool, polystyrene foam, expanded perlite, aerated concrete, rigid polyurethane foam, PVC plastic doors and windows hollow glass so as to reduce the heat transfer coefficient of the building envelope. Hollow brick, two-story windows, etc., the use of air insulation, thermal insulation may also play a role. Additional external walls and roof insulation for winter and summer energy-saving benefit.
