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.

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. Packaged rooftop units superior efficiency greater control unmatched comfort. A chilled water applied system uses chilled water to transport heat energy between the airside chillers and the outdoors.

Rooftop systems trane offers a full line of light and large commercial equipment solutions for new construction and immediate replacement applications. 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. These systems are more commonly found in large hvac installations given their efficiency advantages.

Dx units vary in use between supplemental or emergency building ac or primary ac at tented events or relief structures. Highly efficient enhanced round tube plate fin coils with optional special environmental coating. 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. Manufactured in various configurations these units are designed to provide efficient single or multi zone heating cooling and ventilation. Natural gas electric hot water steam and heat pump heat provide reliable heating for spaces with colder seasons and climates. 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.

Inverter compressors belt less ecm fans and energy recovery solutions make rooftop systems an easy to maintain energy efficient choice for conditioning any space. All gas models utilize induced draft combustion system with tubular heat exchanger. Electric heat units utilize single point wiring connection.
