Jinan Steam Lithium Bromide Refrigeration Machine Recovery

Common Air Conditioning Unit Faults 1. Low Evaporation Pressure: Causes: (1) Insufficient chilled water. (2) Low cooling load. (3) Faulty throttle plate (only causes low evaporation pressure). (4) Heat transfer deterioration in the evaporator due to scale and other contaminants (only causes low evaporation pressure). (5) Insufficient refrigerant charge (only causes low evaporation pressure). Solutions: (1) Check the chilled water circuit to ensure the water volume reaches the rated amount. (2) Check the set temperature of the automatic start/stop device. (3) Verify the畅通 of the expansion throttle pipe. (4) Clean the heat transfer tubes. (5) Refill refrigerant to the required amount. 2. High Pressure: Causes: (1) Insufficient chilled water. (2) Decreased capacity of the cooling tower. (3) High chilled water temperature, excessive cooling capacity, increasing the condenser load. (4) Presence of air. (5) Heat transfer deterioration in the condenser tubes due to scale and other contaminants.

Treatments: (1) Inspect the cooling water circuit and adjust to the rated flow rate. (2) Check the cooling tower. (3) Inspect the expansion throttle pipe, etc., to bring the cold water temperature closer to the rated temperature as soon as possible. (4) Perform exhaust operation to remove air; if the exhaust unit needs to run frequently, locate and eliminate the air leakage. (5) Clean the pipes. 3. Low oil pressure differential: Causes (1) Oil filter clog (2) Oil pressure regulating valve (bleed valve) is open too wide. (3) Decreased output oil volume from the oil pump. (4) Bearing wear. (5) Oil pressure gauge (or sensor) failure. (6) Excessive refrigerant mixed in the lubricating oil (due to oil foaming during startup, causing low oil pressure). Treatments: (1) Replace the oil filter element. (2) Close the oil pressure regulating valve to raise the oil pressure to the rated pressure. (3) Disassemble and inspect. (4) Replace the bearing after disassembly. (5) Check the oil pressure gauge, recalibrate the pressure sensor, and replace if necessary. (6) After the refrigeration unit stops, make sure to turn on the oil heater to maintain the given oil temperature (confirm that there are no broken wires in the oil heater, and that the setpoint for the oil heater temperature control is correct). 4. High oil temperature: Causes (1) Reduced cooling capacity of the oil cooler. (2) Insufficient supply of refrigerant to the oil cooler due to filter screen clogging in the refrigerant filter. (3) Bearing wear. Treatments: (1) Adjust the oil temperature regulating valve. (2) Clean the refrigerant filter screen. (3) Disassemble and repair or replace the bearing after disassembly. 5. Water outage: Cause: Insufficient cold water volume. Treatment: Check the cold water pump and circuit, adjust to normal flow rate. 6. Overload on motor: Causes (1) Unbalanced phase voltage of the power supply. (2) Large voltage drop in the power supply line. (3) Insufficient supply of refrigerant for cooling the main motor. Treatments: (1) Take measures to balance the phase voltage of the power supply. (2) Take measures to reduce the voltage drop in the power supply line. (3) Check and clean the refrigerant filter screen; open the refrigerant inlet valve wider.
