Chillers vs direct expansion

Chill ers vs direct expansion There are a few key differences between chill ers and direct expansion ( DX ) systems that should be considered when selecting a cooling system for your facility . Ch ill ers use a refriger ant to transfer heat from the water being cooled to the air around the ch iller unit . DX systems use a direct expansion of refriger ant in the coils to transfer heat directly from the air to the refriger ant . Ch ill ers are typically more energy efficient than DX systems and can provide a higher level of cooling capacity . Chill ers also typically have a longer lifespan than DX systems . DX systems are typically less expensive to install than chill ers and can be used in smaller spaces . DX systems also typically have a shorter lifespan than chill ers . When selecting a cooling system for your facility , consider the energy ef...
