MVAC System Installation for Hotels & Complex Buildings

System Selection

1. Variable Refrigerant Flow (VRF) Systems
   Ideal for hotels with varying occupancy levels, VRF systems offer individual temperature control in each room, energy efficiency, and quiet operation. They can also recover waste heat for water heating, enhancing energy savings.

2. Centralized Air Conditioning Systems
   Suitable for larger hotels, these systems consist of a central unit that cools the entire building. They provide precise control over the temperature and are relatively quiet, making them ideal for guest comfort.

3. Chilled Water Systems
   Utilizing a central chiller plant to supply chilled water to air handling units located in different zones, this system provides centralized control, good energy efficiency, and flexibility to cater to variable loads.

4. Packaged Terminal Air Conditioners (PTAC)
   Commonly used in smaller hotels or motels, PTAC units are installed through the exterior walls of each room and provide both cooling and heating. They are cost-effective, easy to install, and offer individual temperature control for guests.

Ventilation Considerations

• Fresh Air Supply: Increase outdoor fresh air ventilation by opening outdoor air dampers 100% to enhance effective dilution ventilation per person. The World Health Organization recommends a minimum of 10 L/s per person of fresh air.

• Exhaust Systems: Proper exhaust systems are crucial in areas prone to high humidity, such as bathrooms and kitchens. These systems effectively remove moisture, odors, and pollutants, preventing the growth of mold and maintaining a pleasant indoor environment.
