Water Chiller System Vs Gas Fired Dx Roof Top

Let us see the comparison of dx and chilled water central air conditioning plants.

Water chiller system vs gas fired dx roof top.

The immediate and most noteworthy difference between these two units is that the dx direct expansion unit cools air and chiller units cool water. A chilled water applied system uses chilled water to transport heat energy between the airside chillers and the outdoors. Both of them have their own advantages and disadvantages. Rooftop systems trane offers a full line of light and large commercial equipment solutions for new construction and immediate replacement applications.

These units are well suited to cooling large buildings but they are generally less efficient than dx systems and are not commonly used in homes. With a 3 150 ton capacity range and efficiency ratings as high as 17 5 seer york commercial packaged rooftop units in both a c and packaged heat pump models balance minimized installation and operating costs and come smart equipment enabled. Highly efficient enhanced round tube plate fin coils with optional special environmental coating. The direct expansion dx and chilled water central air conditioning plants are both used at different places depending on the applications and size of the place to be air conditioned.

Dx units vary in use between supplemental or emergency building ac or primary ac at tented events or relief structures. Through the coil cools the water. Inverter compressors belt less ecm fans and energy recovery solutions make rooftop systems an easy to maintain energy efficient choice for conditioning any space. Additionally ahu s will often be connected to central plant such as chillers and boilers to provide the.

Packaged rooftop units superior efficiency greater control unmatched comfort. Electric heat units utilize single point wiring connection. Natural gas electric hot water steam and heat pump heat provide reliable heating for spaces with colder seasons and climates. The same chilled water is pumped through a separate water coil that cools the air stream.

Manufactured in various configurations these units are designed to provide efficient single or multi zone heating cooling and ventilation. A chiller unit outside the building cools the water then the unit pumps the water to heat exchangers inside the building. These systems are more commonly found in large hvac installations given their efficiency advantages.
