What is yrla and XL rla means in chiller compressor nameplate?

Answer 1

In a chiller compressor nameplate, "YRLA" typically refers to the manufacturer's model designation, indicating the specific series or type of the compressor. "XL RLA" stands for "Extra Large Running Load Amperage," which denotes the maximum current that the compressor is designed to draw during normal operation. This information is crucial for ensuring that the electrical supply and protection devices are appropriately sized for the compressor's operation.

Answer 2

"Yrla" and "XL RLA" on a chiller compressor nameplate refer to specific electrical ratings. "Yrla" typically indicates the rated load amperage under specific operating conditions, while "XL RLA" signifies the extra-large rated load amperage, which is often higher due to additional factors like ambient temperature or operational efficiency. These values are crucial for ensuring the compressor is properly sized and protected within the system.
