- 1HVAC Heating Ventilation Air Conditioner1. *Heating & Cooling : -Heat Transfer +Conduction (Heat is transferred by touching) +Radiation +Convection (move with the help of air) -Systems: A. Centralized Heating: Produce heat in one spot and transfers to the whole hotel (Efficient) -Functions 1. Multi Split System - Small Properties - Only Cooling System 2. Hot Water Radiation System - Steam Water (Heat water pipe system) - Delivered to guestroom via baseboard heater,fan coil or radiator 3. Variable Refrigerant Volume(VRV) - Works with refrigerants pipes - Branches - Comes from the main unit and go to the unit - Can heat one room and cool another because it is intelligent enough to send the exact amount of refrigerant that each VRV needs for room - Very Efficient. Works per floor4. Fan Coil System
- Machine to exchange energy
- Fan: Blow air either hot or cold
- We need a boiler (heats water by fuel combustion)
- We need a Chiller (extracts the heat)
- More efficient if - Chiller during summer and boiler during winter (closing valves)
A. Two Pipe System:
- one for Hot&Cold
- one for return to Boiler/Chiller
- Uncomfortable and Efficient (Not expensive)
B. Three Pipe System:
- one for Hot
- one for Cold
- one for return to Boiler/Chiller
- Better Comfort and Energy inefficient (Expensive)
C. Four Pipe System:
- one for Hot
- one for Cold
- one for return to Boiler
- one for return to Chiller
- Best Comfort and Energetic efficiency (VeryExpensive)
