What effect does high compressor discharge temperature have on a refrigeration system?

High compressor discharge temperature is a critical factor in the operation of a refrigeration system. When the discharge temperature is elevated, it often indicates that the compressor is working harder than it should be, which can lead to overheating of the compressor's components. This overheating can subsequently result in mechanical failure, reduced lubrication efficiency, and an increase in wear and tear on the compressor. Therefore, monitoring discharge temperature is essential to maintain the health and functionality of the system, as excessive temperatures may lead to serious operational issues and breakdowns over time.

In contrast to other options, which suggest beneficial outcomes such as improved efficiency or reduced operating costs, high discharge temperature typically signals a problem that must be addressed to ensure the system operates safely and effectively.
