What is a 4 pipe HVAC system?
Likewise, people ask, what is a 4 pipe system?
The four-pipe system includes a distribution system that contains both hot water supply with return lines and a chilled water supply with return lines. Two-pipe systems are less flexible than a four-pipe system. The entire building is in either heating mode or cooling mode.
One may also ask, what is a two pipe HVAC system? A 2-pipe HVAC system is one that uses the same piping alternately for hot water heating and chilled water cooling, as opposed to a 4-pipe system that uses separate lines for hot and chilled water. Two-pipe originated 50 or 60 years ago as a cost-effective way to add air conditioning.
Furthermore, how does a 4 pipe fan coil unit work?
A four-pipe fan coil unit consists of a fan, chilled water cooling coil, hot water heating coil, and air filter. Fan coil units provide conditioned air to the area served by recirculating space air through the coils.
What are the types of HVAC system?
There are four main types of HVAC systems. There are split systems, hybrid systems, duct-free systems, and packaged heating and air systems. Each of these types of HVAC units have pro's and con's, and knowing these factors can help you decide which is best for you.
