2. Types heatingsystems

  • Natural gas and fuel-oil fired equipment.
  • Boilers
  • Electric resitance heating.
  • Electric heat pumps
  • Low temperature radiant heating
  • Solar heating

3. INTRODUCING HEAT LOAD SUPPOSE:

  • High cost energy.
  • Much operating time.
  • Decrease equipment life.
  • Need much maintenance and repair.

REDUCING HEAT LOAD SUPPOSE:

  • Low cost energy.
  • Less operating time.
  • Increase equipment life.
  • Need little maintenance and repair.

4.

  • EXTERNAL:
  • Through the glass.
  • Through the wall.
  • To ventilation.
  • To infiltration.

HEAT LOADS:

  • INTERIOR:
  • To occupants.
  • To lighting
  • By the machines
  • By own installation.

5. IN A AIR CONDITIONING SYSTEM:

  • There is an expansion valve.
  • There is a compressor.
  • There is one condenser.
  • There is an evaporator.
  • There are some fans.
  • There is a electrical system.

6. AIR CONDITIONING

  • In summer:
  • Normally used the refrigerated air and dehumidified.Is very important reduce the humidity by reduce the temperature in to have a confortable climate.

In winter: Normally used the air heating and humidified. Is adbvisable increase the humidity bu increasethe temperature to have a confotable climate . 7. ELECTRICAL SYSTEM OF AIR CONDITIONING:

  • Electrical motors.
  • Lighting systems.
  • Electrical distribution system.
