Too dirty for air conditioning? You don't have to climb! You can wash the ground with this tool plus homemade cleaner
"the air conditioner at 26°c is still hot, the exterior fan is moving fast, i. E. Not cooled, and the maintenance master says the exterior is too dirty. " mr. Zhou, who lives on the 12th floor, looks at the air conditioner outside the window. Air-conditioning exteriors are exposed to long-term outdoors, and can accumulate dust, leaves and oil in six months, and when dispersed, cooling efficiency is reduced by more than 30 per cent and electricity consumption increases by 20 per cent. Post-sale data from an air conditioner brand show that 80 per cent of the summer cooling failures are related to the out-of-air dissipation heat, while regular clean-up of out-of-air machines can maintain 90 per cent of the new machine and extend compressor life by 5-8 years。
Master zhang, who had performed 10 years of air conditioner maintenance, was always equipped with a high-pressure sprayer and homemade cleaning agent. "the outside machine is dirty and can be cleaned without climbing. "his physical record shows that cleaning the outside machine with a "long pole high-pressure water gun plus a little soda cleaner" removes 90 per cent of dust and oil pollution, increases heat-dispersion efficiency by 40 per cent, and saves half of the cost of having someone clean the door. Intuitively more visible in a particular sector: after cleaning, vent temperature dropped from 32°c to 25°c, and indoor temperatures increased significantly. The experience of insiders has shown that the out-of-air conditioners are too dirty to worry about, and with this tool and cleaning agent, they can be handled on the ground and the cooling effect is immediate。
I. Hazards of external contamination: possible burning of compressors as well as poor cooling
"it's like air conditioning' the radiator'cause if it's dirty, it makes the machine"a fever'cause i don't know. " master zhang pointed to mr. Zhou's exterior machine, with a grey and black stain on the radiator tablet and leaves and willows in the cracks. He explained that, when air conditioning was cooled, the external compressor compressed the refrigerant into high-temperature, high-pressure gas, releasing heat through the dispersors and then turning it into a cryogenic liquid flowing into an indoor machine. If the dispersors are blocked by dirt, the heat cannot be released, resulting in:
Three of the most polluting types of external aircraft are on the street or on the side of the road: car tail gas and dust are so high that three months can form oil mud on the dispersed tablets that the speed of congestion is two times that of other environments. Lower level (1-3 floor) aircraft: easily accumulate leaves, willows, insect bodies, especially when the willows fly in the spring, dispersing sheets may be completely blocked. (b) unused off-site machines for a long period of time: after a season change, dust is solidified on the dispersing tablets, the heat is reduced directly when reused, and the fan may be caught by foreign objects。
A simple way to determine whether the outer machine needs cleaning: to observe the colour of the dispersed film (normally silver white, dirty and black), or to touch the outer side of the machine (thermal heat at normal running, excessive heat indicates a dissipation). It is recommended that 1 clean-up before use in the summer and 1 clean-up every 3 months on the street or in a dusty environment to ensure a smooth spread of heat。
Ii. Cleaning instruments: long-barrel high-pressure water gun + homemade cleaning agent to wash on the ground
"the key to cleaning the outside isIt's enough. It's clean'cause i don't know. " the core tool recommended by master zhang is a long-barrel high pressure water gun (scalable up to 8 metres), accompanied by a cleaning agent made of small sodas and vinegar, which removes dust and oil and does not damage external parts. Such a combination, which does not have to climb a building, can clean the outer machine of the 3-10 floor on the ground, and is much safer and more efficient than traditional methods。
Required tools and detergent formulations: home-made cleaning agents (safe and harmless): alternative tools (without high-pressure water pistols): three, cleaning steps: five, no climbing, safe and thorough
"the outside machine must be out of power, press" erase first, then spray, then wash last' the sequence operation. " master zhang's method of washing is on the ground throughout, suitable for most out-of-home machines, with a focus on protecting the circuit parts of the off-site and avoiding access to water。
Specific operational steps for safe power outages and protection: initial flushing, removal of floating dusts: spray cleaners, dissolved oil stains: high voltage flushing, netting of residues: inspection of fans, restoration of electrical power:
Effects: when mr. Zhou's air-conditioning exterior was cleaned, the indoor temperature was reduced from the previous 28°c (at 26°c) to 24°c, the vent temperature became significantly cooler and the noise was reduced when the exterior operated (the fans no longer caused by foreign friction). Master zhang's test showed a 45% improvement in the efficiency of clean exterior heat, a 10°c drop in compressor operating temperature, and an early recovery of cooling effects。
Iv. Special circumstances: these persistent stains are a good idea
" most exteriors can be cleaned using the above methods, and in both cases they need to be addressed in a targeted manner, but there is no need to climb the building. " master zhang summed up two more difficult types of external stains that could be addressed by strengthening the cleaning agent or adjusting the washing method。
Two types of persistent stains and treatment of oil mud or tail gas stains (off the street): willows or leaf jamming (low-level exterior): v. Day-to-day maintenance techniques: reducing external contamination and extending cleaning cycles
" to do these things, the external capacity is maintained for three months without heavy contamination and the cleaning cycle is extended by half. " among master zhang's clients, a house on the street has been maintained, increasing the frequency of cleaning from three to six months once a month, and the external aircraft remains well ventilated。
Practical maintenance techniques for the installation of a safety net: regular and simple washing: cleaning the environment around the off-site: season change maintenance: a guide to hole avoidance: cleaning the off-site is the four most vulnerable bugs of electrical cleansing: this is the most dangerous mistake, hydroconductor power can cause electrical accidents, and it is important to ensure complete power outages, preferably by removing plugs and being guarded. Direct-to-wire sections with high-voltage water guns: external machines have circuit interfaces with components such as compressors, capacitors, and direct spraying leads to short-range burning, should avoid areas with plastic sheeting and be tilted to flush out the heat tablets. Aluminium fin blades and outer casings, such as hydrochloric acid and scalding alkaline, which corrosive thermal tablets, lead to oxidation of rust and must be moderately homemade. Excessive washing of heat sheets: brushing with force with hard hair can deform the fin blades (shrimp, approximately 0. 1 mm thick), but can affect the heat spread and light sweep. "invisible" for air conditioning cooling
The maintenance records of master zhang contain comparative data: regular clean-up of off-board machines with a summer failure rate of only 1/5 for uncleaning and an average refrigeration efficiency of 30 per cent. "a lot of people just focus on interior cleaning, but ignore the outside"at the bottom of the line'it's actually the key to cooling. " he said。
Those who complain about the non-refrigeration of air conditioners and the high cost of electricity are often unaware of the effects of external contamination. In fact, cleaning out machines does not require professional skills, and it costs $200 to buy a long-barrel high-pressure water gun with a homemade cleaning agent two to three times a year to keep air conditioners in optimal condition, saving electricity and maintaining much more than the cost of tools。
Next time i feel the air conditioner cooling's getting worse, don't rush fluorine or switch machines. Let's see if the outside machine is full of dust and clean once using this station's ground, and you'll find that the air conditioner can blow out the stingy cold and the amount of electricity consumed is significantly reduced. Like mr. Chow said in the end, "the water gun that cost $300 is worth the fare at once, and now it's cooler at 26°c than it was at 24°c. " most of the time, the method of making household electricity work efficiently is simple and safe。
