Emerson 12.5kw room air temperature and humidity

Jiang Yue Energy Technology Co., engaged in computer room air conditioning maintenance, service, repair service, strong technical force, rich experience engineer can repair room for treatment of a variety of precision air-conditioning failure, rapid response, to provide users with dedicated computer room air conditioning maintenance, maintenance , overhaul and other services. 1. Circuit portion: n Check the main power supply and various branches of the voltage and current; n Check all contacts, contacts are reliable, instantaneous current detection pull for each contact fastening; to ensure safety;?? for 24V control lines for testing to ensure that control of sensitive; n to detect a variety of system protection features, (such as high pressure protection, low voltage protection, thermal protection, with continued protection, etc.) to ensure the safe operation of the equipment?. ? 2. Control system: n Check the display unit is normal, each set parameters are correct, view the alarm records of the alarm content analysis to eliminate hidden dangers; n clear dust control panel; n measurement control panel battery voltage; n?? ? Check the control panel and the body is fixed is tight. 3. The air filter n? Check the financial dust air filter, replace the air filter failure. Replace every three months to ensure that at least one filter; n Check the filter of the frame and consider the core is deformed;? N for the particular room (eg under construction, etc.), to ensure that the replacement demand?. 4, humidification systems: n Check steam humidifier fouling situation, remove the humidifier tank cleaning; n replace aging humidification electrode and gasket; n replace the deformed humidification barrel:???? N Remove the steam humidifier, Check that the three-phase wet electrode in close contact, if there is damage, ensure the safety circuit humidified; n use maintenance mode to check Sheung Shui is smooth and speed balance; n use maintenance mode to check the drainage open:? n use maintenance mode to check?? three-phase wetting current is balanced and within the normal operating range; n Check the steam outlet is close, steam leakage: n Check whether the steam output to ensure room humidity??. ? 5, intelligent system accessories: n Check the solenoid valve movement is flexible, the presence or absence of leakage interfaces; n Is there a difference in temperature before and after the filter drier; n within sight glass is clean, dry and wet show diaphragm is normal??. ? 6, compressor: n Check the operation of the compressor sound detection operation of the body temperature; n detecting compressor winding resistance, current, compressor insulation; n thoroughly clean all parts of the compressor, replace the compressor?? lubricants, cleaning maintenance pump;? n Check the compressor valve plate airtight seal level status check, check suction and discharge pressure; n detect compressor high and low pressure service valve and other vulnerable parts;? n check high and low voltage protection? , overtemperature protection device. 7, the condenser: n Check the condenser is clean. For cleaning required special cleaning tool to clean outdoor condenser; n fan:??? Check the fan rotation, with or without abnormal noise, running circuit is normal; n Check outdoor condensing the power switch is working properly, insulation reliability, electrical contacts are tightened; n Check the pressure switch, outdoor fan control is consistent with the settings, and then according to the specific work environment to adjust the pressure relay;? n tune? Speed: Check governor operation, the control is sensitive. ? 8, the expansion valve: n open start checking the expansion valve is working properly: n Check the expansion valve bulb back to the trachea in contact with is good; n the temperature difference before and after the expansion valve meets the normal range; n Check the expansion valve regulating valve??? stalk is flexible, connected gap if there is oil leakage;? n the process of checking the expansion valve refrigerant flow running sound is normal. 9, the evaporator: n Check the evaporator is clean, clean if dirt with pesticides, to ensure adequate heat exchange capacity; n Jiang Yue Energy Technology Co. in room for air conditioning maintenance, maintenance, overhaul services, strong technical force,?? Engineers practical experience, can handle a variety of fault repair room dedicated precision air conditioning, rapid response, to provide users with dedicated computer room air conditioning maintenance, maintenance, overhaul and other services.
