Water Chiller System Vs Gas Fired Dx Roof Top

A chilled water applied system uses chilled water to transport heat energy between the airside chillers and the outdoors.

Water chiller system vs gas fired dx roof top. Rooftop units are a type of air handler the main difference is that they are usually more compact and they re always installed on the roof so they need to be more robust and weather proof to deal with the sun rain snow wind etc. Through the coil cools the water. 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. 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. The immediate and most noteworthy difference between these two units is that the dx direct expansion unit cools air and chiller units cool water. Manufactured in various configurations these units are designed to provide efficient single or multi zone heating cooling and ventilation. All gas models utilize induced draft combustion system with tubular heat exchanger.

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. The same chilled water is pumped through a separate water coil that cools the air stream. Gas units utilize integrated gas controller igc with led fault indication. These systems are more commonly found in large hvac installations given their efficiency advantages.

Natural gas electric hot water steam and heat pump heat provide reliable heating for spaces with colder seasons and climates. A chiller unit outside the building cools the water then the unit pumps the water to heat exchangers inside the building. Dx units vary in use between supplemental or emergency building ac or primary ac at tented events or relief structures. 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.

Let us see the comparison of dx and chilled water central air conditioning plants. Inverter compressors belt less ecm fans and energy recovery solutions make rooftop systems an easy to maintain energy efficient choice for conditioning any space. Highly efficient enhanced round tube plate fin coils with optional special environmental coating.
