The fan coil units in big sized commercial and residential buildings can be easily installed with either four or two-pipes, heavily relying on the needs and demands of the buildings, and before you select any particular type of system to install, you should understand the advantages and disadvantages of each and every type of fan coil unit depending on the chilled water fan coil unit manufacturer and chilled water fan coil unit supplier. Let us start with the two-pipe chilled water system.
1) Two-pipe chilled water system
The two-pipe chilled water system is interestingly efficient towards energy. In this particular piping system, there are only two different types of pipes that are attached to the air handlers, boiler, and chiller. One of the pipes in the two-pipe is primarily used for the water loop, while the other pipe is significantly used for the condenser loop.
In summer seasons, the HVAC in the two-pipe system is normally changed to cooling, and in the winter season, the entire system is focused on heating. For the personnel in the maintenance department, this particularly means meeting the significant switch-over dates on the calendar. This process is normally followed by a ceiling fan coil unit supplier in keeping the product safe and reliable at all costs.
Some of the advantages of the two-pipe systems are as follows:
- These pipes are efficient towards energy
- These pipes are the most suitable choice for hotels, apartments, and even condos
- The designs of these pipes are simple
- They are not that expensive in comparison to the four-pipe system
Some of the disadvantages of the two-pipe systems are as follows:
- Two-pipe systems don’t have the capacity for heating and cooling at the same time
- The seasonal temperature in these pipes changes frequently making the entire room uncomfortable.
- These pipes at all costs should be changed from cooling to heating and vice-versa
2) Four-pipe HVAC System
A four-pipe HVAC system is normally regarded as a water source heating pump and is considered as the most reliable, durable, and versatile in comparison to the two-pipe counterparts.
This is purely due to the fact that four-pipe systems normally contain a different kind of pipe system for the heating part of the unit and a completely different kind of pipe system for the cooling part of the unit. Since the cooling and the heating piping systems normally function around two different and distinct kinds of piping systems, the HVAC unit in this regard has the capacity of cooling and heating at the same time, without the demand of the entire unit to be changed or switched from cooling to heating or vice-versa depending on the changes and demands of the season.
This also indicates that if cold or warm weather arrives unexpectedly, the HVAC-based system will easily preserve the temperatures inside keeping the residents at peace and comfort.
Some of the advantages of the four-pipe systems are as follows:
- These pipes can be easily changed and personalized according to the demands of the building.
- These pipes can be simultaneously cool and heat at the same time.
- There’s no particular desire to change the system manually.
Some of the disadvantages of the four-pipe systems are as follows:
- These pipes, in general, are more expensive in comparison to the two-pipe system
- Efficient process of calibration is integral for improving and maintain the energy effectively.
- They are generally expensive, therefore, very difficult to maintain
