Water Chiller System Vs Gas Fired Dx Roof Top

All gas models utilize induced draft combustion system with tubular heat exchanger.

Water chiller system vs gas fired dx roof top.

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. These systems are more commonly found in large hvac installations given their efficiency advantages. The immediate and most noteworthy difference between these two units is that the dx direct expansion unit cools air and chiller units cool water. Natural gas electric hot water steam and heat pump heat provide reliable heating for spaces with colder seasons and climates.

Rooftop systems trane offers a full line of light and large commercial equipment solutions for new construction and immediate replacement applications. Additionally ahu s will often be connected to central plant such as chillers and boilers to provide the. Highly efficient enhanced round tube plate fin coils with optional special environmental coating. A chilled water applied system uses chilled water to transport heat energy between the airside chillers and the outdoors.

Dx units vary in use between supplemental or emergency building ac or primary ac at tented events or relief structures. 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. 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.

Gas units utilize integrated gas controller igc with led fault indication. Through the coil cools the water. Manufactured in various configurations these units are designed to provide efficient single or multi zone heating cooling and ventilation. The same chilled water is pumped through a separate water coil that cools the air stream.

Electric heat units utilize single point wiring connection. 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. Both of them have their own advantages and disadvantages.
