Water Chiller System Vs Gas Fired Dx Roof Top

Gas units utilize integrated gas controller igc with led fault indication.

Water chiller system vs gas fired dx roof top.

Through the coil cools the water. A chiller unit outside the building cools the water then the unit pumps the water to heat exchangers inside the building. Both of them have their own advantages and disadvantages. Inverter compressors belt less ecm fans and energy recovery solutions make rooftop systems an easy to maintain energy efficient choice for conditioning any space.

Manufactured in various configurations these units are designed to provide efficient single or multi zone heating cooling and ventilation. Rooftop systems trane offers a full line of light and large commercial equipment solutions for new construction and immediate replacement applications. Natural gas electric hot water steam and heat pump heat provide reliable heating for spaces with colder seasons and climates. 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.

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. The same chilled water is pumped through a separate water coil that cools the air stream. Highly efficient enhanced round tube plate fin coils with optional special environmental coating.

All gas models utilize induced draft combustion system with tubular heat exchanger. Packaged rooftop units superior efficiency greater control unmatched comfort. Additionally ahu s will often be connected to central plant such as chillers and boilers to provide the. Electric heat units utilize single point wiring connection.

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