In the evolution of modern home appliances, refrigerators have become increasingly advanced, focusing on precise temperature control, fast cooling, energy efficiency, and enhanced food preservation. At the core of these improvements lies the airflow cooling system, powered by a highly efficient DC motor.

In this case study, a well-known refrigerator brand sought to upgrade its cooling system for a new high-end model. After multiple evaluations, they selected the Chungfo HTD05036S12 DC motor as the driving force behind the internal air circulation system.

1. Why Refrigerators Require High-Performance DC Motors

A frost-free refrigerator relies on strong, stable airflow to distribute cold air evenly throughout various compartments. If the motor underperforms, the unit may suffer from:

Uneven temperature distribution

Longer cooling time

Higher power consumption

Localized cold spots

Reduced freshness retention

Therefore, refrigerator manufacturers set strict requirements for motor performance, including:

High rotation speed

Low noise

Long lifespan

Low energy consumption

Stable airflow pressure

The HTD05036S12 DC motor fully meets these conditions.
