  Maintaining optimal temperatures in   HVAC chiller system   components is essential for their efficient operation. Abnormal temperature ranges can signal potential issues that need timely analysis and intervention. While precise temperature measurements might be challenging, manual estimation by touch often helps in detecting these anomalies. Here’s an in-depth look at ten critical temperature points for effective chiller maintenance. 1. Discharge Temperature Normal and Abnormal Conditions: • High Discharge Temperature: During summer, the compressor’s discharge temperature is high and untouchable. This may indicate high suction temperatures or excessive condensing temperatures. • Low Discharge Temperature: If the discharge pipe is not hot, it suggests very low suction temperatures or low refrigerant levels, potentially causing valve structure damage or insufficient motor winding cooling. 2. Compressor Shell Temperature Impacts and Causes: • Normal Temperature: The shell...
