HVAC SYSTEMS

You can expect 8-12 months return on your investment, when you install a new or upgrade an existing HVAC system with automation by CSU. But the energy and money saving features are even not the ones that make our systems so attractive -- it is the unsurpassed level of comfort delivered everywhere in your house. Our systems rely on automation to enable users to control temperature and humiduty in each room individually. In addition, the continuous air exchange guarantees quick removal of odor and polutants from any affected area, without compromising the comfort in the other rooms.

The diagram below shows a principal scheme of the air flow used by our systems:

Fig.1 Airflow diagram
  1. External fresh air inlet.
  2. Heat Exchange Unit. Exhaust air to be released in the atmosphere is used to normalize the temperature of the incoming fresh air. Both air flows are maintained separated.
  3. Fresh air intake conduit. Supplies fresh air to the distributor.
  4. Distributor. Electronically controlled, it manages the air flowing into the cooling and heating units and the ratio of fresh to recycled air.
  5. Air supply ducts. Supply air to the heating and cooling units.
  6. Electrostatic filters. Remove the smallest particles of dust, smoke, pollens and other contaminants.
  7. Cooling (A/C) Unit. Electronically controlled, cools down the intake air to a temperature as a function of demand and other environment variables.
  8. Cold air fan. Variable speed turbine type fan that maintains certain (positive) pressure in the cold air column.
  9. Cold air column. Delivers cold air throughout the building.
  10. Heating (Furnace) Unit. Electronically controlled, heats up the intake air to a temperature as a function of demand and other environment variables.
  11. Warm air fan. Variable speed turbine type fan that maintains certain (positive) pressure in the warm air column.
  12. Warm air column. Delivers warm air throughout the building.
  13. Fresh air inlet. Electronically controlled, it allows a mixture of cold and warm air from the respective columns in the room.
  14. Exhaust air outlets. Electronically controlled, remove exhaust air from the room.
  15. Exhaust air column. Delivers the exhaust air from the building back to the power plant to complete the cycle.
  16. Exhaust air fan. Variable speed turbine type fan that maintains certain (negative) pressure in the exhaust air column.
  17. Recycled air distributor. Electronically controlled, it manages the volume of exhaust air released in the atmosphere and the portion of it used for recycling.
  18. Exhaust air conduit. Air to be released is forced into the Heat Exchange Unit, where it is used to normalize the temperature of the incoming fresh air.
  19. External exhaust air outlet.
