Attention to air conditioners
1. Test the normal functioning of air conditioners before moving。
2. Recovery of refrigerants and removal of internal and external connections. It is good to be able to mark at both ends of the connection line, not only because of the possibility of faulting the connection while on board。
3. During the process of handling and installation of an external aircraft, it is not possible to reverse it, the tilt angle is too large, and it is forbidden to hold the valve lift by hand。
4. Whether the end-of-wire or other connected locations are relaxed to prevent fires or other hazards, and whether the wire is ageing, if any, must be replaced。
5. Old air conditioners cannot be reopened within three minutes after they are shut down, otherwise compressors are easily burned. New air conditioners have circuits to prevent re-opening within three minutes, and compressors do not work even if they are re-opened within three minutes。
The air conditioner migration process appears to be simple, and the erosion contains many details that require attention and, if the air conditioner mover is not operating properly, it is likely that the air conditioner will operate the air conditioner。
Other things that air conditioners do not wash for long periods of time, such as: increased power consumption, increased noise, slower cooling of heat, poor cooling of heat. So the air conditioners must be washed in depth at spring and fall! Air-conditioning depth cleaning can only be performed by personnel, with the application of detergents accompanied by air-conditioning cleaners, and with the implementation of air-conditioning from detachment depth cleaning! Without disrupting the air conditioner balance, allowing air conditioners to recover faster to their working condition when they leave the factory
The selection of the right tools is essential for maintenance. The use of inappropriate tools may result in damage to equipment or an inability to solve problems effectively. Ensure that tools are available and understood for proper use of central air conditioning maintenance。
Usually, 30 per cent of the comfort ac cool load is intended to eliminate sub-heat loads and 70 per cent is intended to eliminate thermal loads. The situation varies widely for the rooms, which consist mainly of heat from the dispersed equipment, heat from the indoor staff and hot and wet from fresh air entering the rooms during the summer (only 5 per cent of the total). In addition, the need to get wet rather than wet during the winter, even in the winter room, where the heat load is still to be removed, especially in the control room, is particularly relevant in view of the above-mentioned characteristics, which can result in waste of energy if general comfort air-conditioning units are used in the room。
The change usually takes place between 10 and 20 per cent, owing to the different working conditions of the mainframe equipment and the different working hours consumed. Thus, room air-conditioning systems are able to adapt to such load changes so that electrons work within the required environmental conditions to ensure the reliability of circuit performance。
With the development of our national economy and the growing standard of living of our people, air conditioning has been transformed from the concept of household appliances into household appliances for household use and into 100 households; the pace of development has been much faster than expected. There is a deep awareness of the energy consumption of air conditioners, which is highly developed; however, at the national level, as air conditioning has just become widely available, the “cleaning industry” is still a blank, air-conditioning cleaning is a novelty, and many have never heard of it before, and it is good for human health and improved air-conditioning performance, which can be immediately effective, with excellent lip service。
