A Daikin Chiller compressor thermal switch might open due to operating beyond design conditions (add facilities so that conditions are within allowable limits) or a discharge valve being partially shut (open valve).
What causes high discharge pressure in Daikin Chiller?
High discharge pressure in your Daikin Chiller can be caused by: * Insufficient condenser water or water temperature being too high; readjust the temperature control or water regulating valve and investigate ways to increase water supply. * Fouled condenser tubes (water-cooled condenser), clogged spray nozzles (evaporative condenser), or a dirty tube and fin surface (air cooled condenser); clean the affected components. * Noncondensables in the system; have the noncondensables purged. * System overcharge with refrigerant; remove excess refrigerant. * Discharge shutoff valve partially closed; open the valve. * Condenser undersized (air-cooled); check condenser rating tables against the operation. * High ambient conditions; check condenser rating tables against the operation.
How to fix low suction pressure on Daikin WGZ030DW?
Low suction pressure in your Daikin Chiller can stem from several issues: * Lack of refrigerant; check for leaks, repair them, and add refrigerant. * A dirty evaporator; clean it chemically. * A clogged liquid line filter-drier; replace the cartridge(s). * Clogged suction line or compressor suction gas strainers; clean the strainers. * A malfunctioning expansion valve; check and reset for proper superheat, replace if necessary. * Condensing temperature too low; check the means for regulating condensing temperature. * Compressor will not unload; see corrective steps for failure of compressor to unload. * Insufficient water flow; adjust the flow.
What causes noisy or vibrating Daikin Chiller compressor?
A noisy or vibrating Daikin Chiller compressor can be attributed to: * Flooding of refrigerant into the crankcase; check the superheat setting of the expansion valve. * Improper piping support on the suction or liquid line; relocate, add, or remove hangers. * A worn compressor; replace it.
What causes little or no oil pressure in Daikin WGZ030DW Chiller?
Little or no oil pressure in your Daikin Chiller can be caused by: * A clogged suction oil strainer; clean it. * Excessive liquid in the crankcase; check the crankcase heater, reset the expansion valve for higher superheat, and check the liquid line solenoid valve operation. * Low oil level; add oil. * Flooding of refrigerant into crankcase; adjust thermal expansion valve.
