To align with these stricter environmental standards and avoid regulatory penalties, major manufacturers shifted their product strategies, with nearly 75% of newly launched HVAC systems using R-32 or R-454B refrigerants. Moreover, governments across major economies are introducing policies aimed at reducing carbon emissions, improving energy performance, and phasing out refrigerants with high global warming potential (GWP).
What are the Classification of HVAC systems?
The major classification of HVAC systems is central systems and decentralised or local systems. The type of system depends on whether the primary equipment is centralised, conditioning the entire building as a single unit, or decentralized, conditioning a specific zone separately within the building. Therefore, the air and water distribution system should be designed based on the system classification and the location of the primary equipment. The criteria mentioned above should also be applied when selecting between the two systems. The table compares central and local systems according to the selection criteria.
| Criteria | Central system | Decentralized system |
| Temperature, humidity, and space pressure requirements | Fulfilling any or all of the design parameters | Fulfilling any or all of the design parameters |
| Capacity requirements | Considering HVAC diversity factors to reduce the installed equipment capacity | Maximum capacity is required for each equipment |
| Redundancy | Standby equipment is accommodated for troubleshooting and maintenance | No backup or standby equipment |
| Special requirements | An equipment room is located outside the conditioned area, or adjacent to or remote from the building | Possible of no equipment room is needed |
| First cost | High capital cost | Affordable capital cost |
| Operating cost | More significant energy efficient primary equipment | Less energy efficient primary equipment |
| Maintenance cost | Accessible to the equipment room for maintenance and saving equipment in excellent condition, which saves maintenance cost | Accessible to equipment to be located in the basement or the living space. However, it is difficult for roof location due to bad weather |
| Reliability | Central system equipment can be an attractive benefit when considering its long service life | Reliable equipment, although the estimated equipment service life may be less |
| Flexibility | Selecting standby equipment to provide an alternative source of HVAC or backup | Placed in numerous locations to be more flexible |
