The salt city central air conditioning service, which specializes in the provision of various indoor air conditioning services, central air-conditioning ventilation systems and comprehensive solutions in such places as writing buildings, hotels, entertainment areas, restaurants, shops, government offices, hospitals, schools, terminal buildings, railway stations, factories, power plants and houses。
Central ac condenser cleaning process
1. The dirt formed by the sub-units consists mainly of carbonate platinum, which is equilibrated on the inner walls of the condensers and evaporating copper tubes. The scales are white or grey and cross-sections in a granular form, hard and hard, with strong ties。
2. A valve with pressure meters or thermometers is installed on the main water cleaning cycle water import and export pipeline of the cooling water unit. When cleaning, the valves are closed and the soft water hoses, specialized preservative pumps and acid tanks are connected to the circulatory system with an export/import pressure gauge thermometer or port to calculate the volume of the cleaning cycle。
3. The volume of the cooling agent is based on the total capacity of the cleaning cycle water, with the washing of the cooling agent to prevent the reaction of acid and copper tubes。
The water is mainly calcium carbonate, and the washing agent is hrc-q1, mainly composite solid organic acid, white crystals, low corrosivity to metals, weak acidity, and the use of the washing agent depends on the amount of equipment. If the water is thicker, the detergent needs to be added。
4. Cleaning agents
If the equipment is thicker and the detergent is needed, the detergent can facilitate the rapid dissolving of the products following the sediment reaction into water and accelerate the deep distillation response。
5. Cleaning process
1) cleaning temperature: the usual use of constant temperature washing. If the water is thicker, it can be washed at 40-50 degrees, increasing its speed。
2) closure of the valves for the import and export of the crew and the use of pressure meters or thermometers, preservative pumps, acid tanks as a cleaning cycle system. In the process of cleaning, a cooler is added, so that the smoother is cycling and organic acid is slowly added. When washing, periodic checks of reactions are carried out to replenish the washing agent and to ensure sufficient acid and waterfall reactions. When washed, appropriate quantities of determinators, blowing agents and additives are added, depending on the reaction。
3) after cleaning, residual liquids shall be discharged and washed with water。
4) for thick cleaning, passivated agents should be added to prevent internal metal wall oxidation。
5) purge time of about 5-10 hours, depending on the actual situation。
Grid central air conditioning network maintenance point query
Refrigerants are inadequate: simple self-measurements can be performed to identify fluorine leakage。
Four-barrel collusive gas: thermal pump air conditioning is replaced by four-barrel switching for refrigeration and heating. Some refrigerants that should have been actively involved in the heat exchange flow directly from the compressor vents to the vents, leading to fewer refrigerants for student participation in the heat exchange and significantly less efficient heat exchange technologies, resulting in inadequate capacity development for heat preparation。
The auxiliary electrical heating function is not functioning. If the electro-heating control circuit or the electro-heating device is not working properly, the heating capacity of the air conditioner is insufficient at lower ambient temperatures, and even in harsh environmental conditions, the air conditioner does not make the heat at all。
For thermal pump technology-aided electro-thermal air conditioners, if the temperature requirements in the enterprise environment are higher (more than 5) and heat is normal, but the environment and when the temperature is relatively low (below 0) does not have sufficient capacity to heat or does not heat, it should be suspected that the electro-aided heat control work circuits or electro-aided heat units have malfunctions, and the maintenance should focus on monitoring and inspection of both components。
The main services in salt city are: commercial central air conditioners, home air conditioners, domestic central air conditioners, decomposition, repair, maintenance, fluorine, perforation, disinfection, maintenance, cleaning, etc., and provide a perfect solution for the design of the household central air conditioners。
As the number of users increases, the amount of salt city maintenance increases; the hotline is easy to reach; please dial more times; please understand!
