All Air Conditioners Are Oversized!
The Unavoidable Design Flaw
____________________
Most AC systems are oversized and often fail temperature and humidity control demands. This oversizing is a necessary evil to absolutely ensure basic cooling demands are met. But the tendency of oversizing leads to short cycling – a phenomenon that causes humidity control challenges, air quality problems, as well as reliability and maintenance issues in standard staged dx air conditioning equipment.
Key Benefits of APR Control
- Eliminates High Humidity
- Reduces Temperature Fluctuations
- Extends Compressor Lifespan
- Protects Refrigeration Circuit
- True load-matching up to 80% turndown on standard DX
- Use it everywhere to meet space requirements
