Why is my Trane CGWH 115 Chiller's cooling capacity insufficient?
If your Trane Chiller isn't cooling sufficiently, it might be due to: * Not enough refrigerant: Check the refrigerant circuit for tightness and add refrigerant. * A clogged drier filter: Replace the filter. * Superheat not properly adjusted: Check and adjust the thermostatic expansion valve. * Obstructed chilled water pipes: Clean the pipes and strainer.
What causes loss of oil in Trane Chiller compressor?
If there is loss of oil in the Trane Chiller compressor, it could be due to: * Not enough oil: Contact Trane Office before to order oil. * A clogged filter drier: Replace the filter drier. * Liquid flowing back to the compressor: Adjust superheat and check the bulb fixing of the expansion valve.
Why does my Trane CGWH 115 Chiller compressor stop, indicating a high pressure switch tripped?
High discharge pressure can cause the Trane Chiller compressor to stop. This might happen because the voltage is too low, the cooling demand is too high, the condensing temperature is too high, or there isn't enough cooling fluid. Also, low water flow to the evaporator can be a factor. To address this: * Refer to instructions for “discharge pressure high.” * Contact the Power Supply Utility if the voltage is too low. * Repair any leaks and add refrigerant. * Check the water flow rate and the pressure switch contact in the water.
Why does the Trane Chiller compressor keep running without stopping?
If your Trane Chiller compressor is running non-stop, it could be due to: * Excess load on the cooling system. * Existing cooling demand on the system. In both cases, check the thermal insulation and air-tightness of the areas requiring air-conditioning.
What causes high discharge pressure in a Trane CGWH 115?
High discharge pressure in your Trane Chiller can be caused by: * Uncondensable liquids in the system or excess refrigerant: Purge uncondensable fluids and drain off excess refrigerant. * Overload on the cooling system: Reduce the load on the system and reduce water flow if necessary. * Reduced air flow or air intake temperature higher than specified: Clean the battery and check the operation of motor fans.
Why is my Trane CGWH 115 Chiller compressor noisy?
A noisy Trane Chiller compressor can be due to: * Broken components inside the compressor: Change the compressor. * Uneven liquid flow or an expansion valve locked in the open position: * Check superheat setting and fixing of expansion valve bulb. * Repair or replace the expansion valve.
What causes suction pressure to be too high in a Trane CGWH 115?
If the suction pressure in your Trane Chiller is too high, it could be due to: * The expansion valve being too far open: Check the system. * The expansion valve being locked in the open position: * Check for superheat and ensure the expansion valve bulb is secure. * Replace the expansion valve.
What causes suction pressure to be too low in a Trane Chiller?
If the suction pressure in your Trane Chiller is too low, it could be due to: * A clogged drier filter or an expansion valve bulb that has lost its refrigerant: Replace the deshydrator and the bulb. * An obstructed expansion valve: Replace the valve. * Excessive pressure drops through the evaporator: Check and adjust the superheat and adjust the thermostatic expansion valve.
