When Does The Condenser And Heat Exchanger Need To Be Cleaned?
After the first year of operation, the energy efficiency ratio of general air conditioners will decline by 8% (8%); after three years of operation, the energy efficiency ratio of air conditioners can drop by as much as 25% (25%). According to inquiries from more than 300 star-rated hotels across the country, the various central air conditioners currently used in hotels will attenuate significantly after working for a period of time. Central air conditioners that work for a long time have an energy efficiency ratio that can be attenuated. Twenty-five percent (25%) or more constitutes a waste of power expenditure of the utilization unit.
The condenser of the central air-conditioning unit has high scale pressure and the exhaust temperature increases. The high-pressure protection device of the unit initiates to automatically stop the central air conditioner; the central air-conditioning unit evaporator has some water temperature lower than the set temperature (condensation), and the unit low-temperature protection device initiates , Make the central air conditioner automatically shut down; the temperature difference between the cooling water in and out of the central air conditioner is lower than 2～2.5℃, the heat exchange effect is poor, the cooling capacity is reduced, and the power consumption rises; the central air conditioning cooling tower has bacteria, algae and scale formation, blocking condensation Piping, high-pressure shutdown;
The temperature difference between the inlet and outlet of the refrigerant water of the central air-conditioning unit is less than 2℃, the cooling capacity cannot be released, and the air-conditioning effect is poor; the refrigerant water temperature of the central air-conditioning unit cannot be lowered, and the set temperature of the unit cannot be reached, and the air-conditioning effect is poor; the refrigerant of the central air-conditioning unit The water temperature can reach 7-8℃, but the air-conditioning effect is still not good; the aluminum fins of the central air-conditioning air-cooled unit are stuck with dust, and the air-conditioning heat dissipation effect is not good.
The scale in the fan coil of the central air conditioner is attached to the pipe wall, clogging the filter, reducing the flow rate and heat exchange effect; some rooms have good air-conditioning effects, and some rooms have poor air-conditioning effects; some rooms have large air-conditioning air volume, but indoor temperature High, no cool air; abnormal smell in the room when the central air conditioner is turned on, and the air quality is not good; the condensed water in the central air conditioner's collecting pan overflows and leaks, causing water leakage on the roof and damage to the decoration.
The water quality of the central air-conditioning refrigerant water is yellow or black and the accumulation is serious; the pipeline equipment of the unit is corroded seriously. The central air-conditioning fan coil and wind blades are covered with dust, and the air volume at the air outlet becomes smaller.
The newly installed central air-conditioning system has just been in operation for less than a year, and the above-mentioned related questions have arisen. The emergence of many bad working conditions makes the central air conditioner not work properly. If your central air conditioner has one of the above questions, it is generally caused by non-mechanical failure factors, and central air conditioner cleaning and central air conditioner water treatment should be done.
