It's windy, and the indoor opportunity is knocking at the door. What happened?

When there is wind outside, check whether it exists. The wind flows back to the indoor air conditioner along the drain pipe of the condensed water of the indoor air conditioner, which makes the indoor air conditioner produce blowing noise. In this case, it is suggested that the end nozzle of the condensate drain pipe leading to the outdoor of the indoor unit of the air conditioner be made into a "U" shape, and the back edge of the U-shaped bend is lower than the front edge to prevent the wind from flowing backwards.

Generally, the installation location of air conditioners should avoid heat sources, and the removal of hot air and noise interference should not affect neighbors. The installation height of outdoor unit should be lower than that of indoor unit, which is beneficial to the circulation of refrigeration oil. The outdoor unit shall be installed to avoid short-circuit circulation of hot air, so as not to affect heat dissipation: the installation position shall be convenient for maintenance and drainage, and shall not affect pedestrians, and avoid or stay away from high-voltage lines, radioactive places and inflammable and explosive places. There should be no obstacles in front of the indoor unit installation, and the spraying distance of cold air (or hot air) should be ensured to make the indoor temperature more uniform.

On-off maintenance of air conditioner

After the air conditioner is turned on, it is necessary to determine the maintenance frequency during the start-up of the air conditioner according to various factors such as environmental conditions, climate conditions, start-up time, surrounding dust, air cleanliness, indoor cleanliness and so on. Poor environmental conditions, hot weather, outdated air conditioning, long start-up time of air conditioning, and increased maintenance times during air conditioning start-up, generally once a month and a half.

If the environmental conditions are good, the air conditioner is relatively new, there is less dust in the air, and the air conditioner can be turned on reasonably and can be used alternately with the electric fan, then the maintenance cycle can be extended appropriately, from air conditioner on to air conditioner off 1-2 times. Maintenance should be careful and meticulous, leaving no dead ends. Reach the standard, improve the cooling speed and effect, and achieve energy saving, freshness and comfort.

It is a perennial law to turn on the air conditioner when the weather gets warmer and turn off the air conditioner when the weather gets cooler. Pay attention to the comprehensive and detailed inspection of outdoor units and indoor units before the air conditioner is turned off. Maintenance, maintenance and cleaning should be done one by one. Leaky links should be tightened and strictly checked. After the above steps are completed, cover the air conditioner to prevent dust pollution, prevent the air conditioner from dripping into water, keep it clean, prepare for reuse next year, save energy and prolong the service life of air conditioning equipment. Focus on protecting high-quality distributors and cabinets of well-known brands, and give full play to the energy-saving effect.
