The importance of central air conditioning cleaning

In the normal working process of central air conditioning, metal corrosion products such as scale, algae, biological slime and rust will appear in the water system, and these substances will continuously accumulate in the condenser , heat exchanger, inside of fan coil and inside of the pipeline, the flux of the constituent pipeline becomes smaller, which affects the heat exchange effect Moreover, because the thermal conductivity of the dirt is relatively low, when the dirt accumulation is covered on the heat exchange surface of the heat exchanger, it will greatly reduce the efficiency of the cooling and heat exchange, resulting in the increase of the pressure of the condenser, the direct decrease of the cooling effect and the substantial increase of the power consumption Dirt also accelerates corrosion and shortens the life of the central air conditioning unit Therefore, in order to save power and extend the service life of the central air conditioning unit, the central air conditioning cleaning is very beneficial In the process of central air conditioning work, scaling, rusting, cooling effect decreasing, power consumption rising, and even high-voltage tripping occurs in serious cases After five processes of central air conditioning cleaning by Kunshan Tuochuang, the cooling effect of central air conditioning is significantly improved, the working time of the compressor is saved, the power consumption of the unit is saved by 10-30%, and the service life is extended For example, before cleaning a room, it takes 10 minutes to reduce to the set temperature; after cleaning the central air conditioner, it only takes seven minutes to reduce to the set temperature, so the compressor can work for three minutes less, and then save 30% of electricity Nowadays, China's current situation is that many central air conditioners have poor refrigeration effect, which leads to the extension of tightening time and waste of power After cleaning the central air conditioner, it can make the air conditioner return to normal refrigeration effect, shorten the tightening time and save 10-30% of electricity I The importance of central air conditioning water system cleaning The water system of central air conditioning is divided into two systems: cooling water and chilled water: 1 The cooling water system mainly relies on the cooling tower to dissipate heat The water will fully contact with the air after splashing and moving in the cooling tower Then, a lot of dust, microorganism, soluble salt and corrosive gas in the air will be brought into the cooling tower to make the concentration of water impurities increase continuously, which brings a lot of harm to the work of the central air conditioning system Hazard performance: dust, salt, bacteria, dissolved oxygen, etc → scale, bacteria and algae, rust residue → accumulated in the copper tube and filter of the main engine → slow circulation → poor heat dissipation effect → poor refrigeration effect → waste power → shorten the life of the equipment The refrigeration system is a sealed system The dissolved oxygen in the water is very simple to form a blocked coil The unit and pipeline accessories are corroded Then the cooling capacity is decreased and the equipment is damaged too early, which directly affects the normal operation of the central air conditioning system Hazard performance: water corrodes the inner wall of the pipe → rusts → blocks the main coil and fan coil → causes the coil to crack or has no cooling effect → wastes power → shortens the service life of the equipment The condenser of the central air conditioning unit has high scale pressure, the exhaust temperature increases, and the high-pressure protection equipment of the unit initiates the automatic shutdown of the central air conditioning unit; some water temperature of the evaporator of the central air conditioning unit is lower than the set temperature (condensation), and the low-temperature protection equipment of the unit initiates the automatic shutdown of the central air conditioning unit; the temperature difference of the cooling water in and out of the central air conditioning unit is lower than 2-2.5 ℃, the heat exchange effect is poor, the cooling capacity is reduced, and the power consumption is increased; bacteria, algae and scale are generated in the cooling tower of the central air conditioning, the condenser pipeline is blocked, and the high-pressure shutdown occurs; the temperature difference between the inlet and outlet of the cooling medium water of the central air conditioning unit is lower than 2 ℃, If the cooling capacity cannot be released, the air conditioning effect is poor; if the temperature of the cooling medium water of the central air conditioning unit cannot be lowered, the air conditioning effect is poor; if the temperature of the cooling medium water of the central air conditioning unit can reach 7-8 ℃, but the air conditioning effect is still poor; if the aluminum fins of the central air conditioning unit stick to dust, the air conditioning cooling effect is poor The scale in the fan coil of central air conditioning is attached to the pipe wall, blocking the filter, reducing the flow and heat exchange effect; some rooms have good air conditioning effect, some rooms have poor air conditioning effect; some rooms have large air volume, but the indoor temperature is high, there is no cool air; when the central air conditioning is on, there is abnormal smell in the room, and the air quality is poor; The condensation water in the central air conditioning water collecting plate overflows, causing the roof leakage to damage the decoration; the water quality of the central air conditioning cooling medium water is yellow or black and the accumulation is serious; the pipeline equipment of the unit is seriously corroded The central air-conditioning fan coil and blades are covered with dust, and the air volume at the air outlet becomes smaller; the newly installed central air-conditioning system has just worked for less than one year, and the above-mentioned problems have occurred The appearance of the bad working condition makes the central air-conditioning unable to work normally If there is any doubt about your central air conditioner, it is generally not caused by mechanical failure factors You should clean the central air conditioner and treat the central air conditioner water immediately Sichuan keyikang cleaning water treatment technology Co., Ltd provides customers with excellent central air conditioning cleaning and central air conditioning water treatment effectiveness Kunshan Tuochuang refrigeration mechanical and Electrical Co., Ltd is a cleaning commercial central air conditioning air system (air duct, air cabinet, coil, tuyere, filter screen, etc.), central air conditioning water system (cooling water, chilled water system, host cleaning), central air conditioning ventilation system check, air conditioning water treatment cleaning, repair, maintenance and other special effectiveness company.
