【 Weak current College 】 air-conditioning installation should pay attention to the "three leakage problem"---Power By 【 China power house network 】

The appearance of the check air conditioning process, first of all should pay special attention to the air conditioning in all parts of the installation was solid and reliable, pipe or pipes and parts for mutual friction and collision. The second key check air-conditioning evaporator, condenser of manufacturing quality, these two parts of quality directly affects the air conditioning cooling effect. Evaporator, condenser fins, a clearance should be neat and tidy is not uniform, "collapse". Fin in flanging there should be no cracks, fin received should be tightly packed in brass, not loose, otherwise it will reduce the evaporator, condenser heat transfer efficiency, cooling capacity decrease. Once again, on manual vertical, horizontal wind plate should be able to pull up and down or left and right should not be too tight, not too loosely, should be allocated in any location to location, should not automatically shift. In addition, the filter is often disassembly and Assembly of parts, care should be taken to check for Assembly and disassembly are convenient, has broken, etc. By computer-controlled air conditioner, remote control, cable controller on the feature selection button light, flexible, dislocation, not loose.

Air conditioning installation is ready, the consumer must also pay special attention to the "three leakage problem", namely, the leakage of refrigerant leakage, water leakage,. Consumers can use the following methods check leakage: detection with a crafty, if there is a strong light, is a serious leakage; touch air conditioning shell and knobs have linen hand feeling, check with a crafty, micro-light is slight leakage. Air leakage is the destruction of electrical insulation, electrical shock to the human body, to be very careful. Check refrigerant leakage of refrigerant leakage to note that air conditioning in the capillary export to the evaporator entry there will be some frosting, and other parts of a small amount of gel or drier frost-free, compressor suction pipe temperature close to ambient temperature. Finally examine the leakage. Water is mainly due to the machine itself with water pipes and spare tube at connection time is not waterproof, consequently, in the air conditioning installed, you should do about waterproof test, with a glass of water poured into the Interior of the evaporator, the water can flow to the outside, there would be no problem.

Air conditioning noise size is also requires a detailed examination. During the installation of air conditioning process, when the gadget installation not tight, screws loose, fan Assembly, compressor failure, etc., the air conditioning noise, vibration, friction, impact and other abnormal noise. In addition, if the air conditioning was installed in the hollow walls, will form a resonance and noise.

In addition to also check the air conditioning and refrigeration. Run the normal air conditioning in the strong cold retaining power run after 5 minutes, it should be cold winds blow out, the evaporator surface dew, condenser should be hot air blow out.
