The fault pattern of industrial chillers can be divided into three stages

During use, the performance of a chiller will gradually decrease over time. In fact, many faults have some precursors before they occur, which are commonly referred to as potential faults.
The failure rate of a chiller also varies over time, which is commonly referred to as its lifespan.

1. Phase 1: Early Failure
Early failures, also known as the break in period, have a high failure rate, but they also decrease over time. Early failures are caused by unreasonable design structure, environment, installation, and other factors.

2. Phase 2: Occasional malfunction
Occasional faults belong to randomly generated faults, which have a low failure rate and are basically in a stable working state.

3. Third stage: Loss fault
After long-term use, the failure rate of the chiller has significantly increased in the later stage, which is caused by wear, aging, corrosion and other reasons of various components.

In the later stage of use of the chiller, which is also the most prone to malfunctions, it is necessary to carry out daily maintenance and repair work to prevent larger problems from occurring.
