  2. 2. A system of process for controlling the lowering the temperature dan humidity of an enclosed space.
  3. 3. COMPRESSOR Inhaling the refrigerant from the suction channel - Compressing to the discharge channel. Hot refrigerant vapor and high pressure CONDENSOR Remove heat from condenser Refrigerant vapor turn to liquid. Hot refrigerant vapor and high pressure EXPANSION VALVE Low the temperature and  pressure of liquid Control the flow rate in to the evaporator. Cold refrigerant vapor and low pressure EVAPORATOR Liquid turns to vapor Cold air flows out room. Cold refrigerant vapor and low pressure
  4. 4. CONDENSOR EVAPORATOR COMPRESSOR EXPASION VALVE HP LP
  5. 5. Window Air-conditioning System  Window air-conditioner units are a reliable  Simple to install solution  Easily removed for storage Split Air-conditioning System • The outdoor unit and the indoor unit.  Durable  Simple to install
  6. 6. Package Air-conditioning System  Used for the cooling capacities in between these two extremes.  The packaged air conditioners fixed rated capacities of 3, 5, 7, 10 and 15 tons.  Used commonly in places like restaurants, telephone exchanges, homes, small halls. Low Statics Fan Coil • One or more heat exchangers • One or more fans with electric motors • An appropriate enclosure, • Condensed water collecting facilities when cooling
  7. 7. Set Tool Refrigerant Gas Manifold Gauge
  8. 8. Vacuum Pump Chemical Meter Ampere
  9. 9. Refrigerant leaks can happen with vibration of the unit while it is operating. Dirty A/C units wont operate at peak efficiency. (Coil Condensor)
  10. 10.  One possible reason that HVAC systems blow warm air is dirty filters. Frozen coils are causes circulation problems.
  11. 11. CONCLUSION
