Claims
- 1. A method of controlling the internal environment of a building for human occupancy, the method comprising:providing at least one air handling unit including at least one fan for inducing air movement within the building; flowing air directly through the at least one fan and into the building; continuously operating the at least one fan at a reduced speed continuously; sensing at least one internal environmental parameter; and varying a speed of the at least one fan according to the at least one sensed internal environmental parameter.
- 2. The method according to claim 1, further comprising sensing humidity from an external environment.
- 3. The method according to claim 1, further comprising sensing at least one parameter of an environment external to the building and admitting external air into the internal environment and regulating flow of the external air in response to at least one sensed external temperature.
- 4. The method according to claim 1, further comprising sensing external ambient temperature, selecting a maximum external ambient temperature value and decreasing admittance of external air if the maximum external ambient temperature value is exceeded.
- 5. The method according to claim 4, wherein decreasing the admittance of external air comprises decreasing the speed of the at least one fan.
- 6. A method of controlling the internal environment of a building for human occupancy, the method comprising:providing at least one air handling unit including at least one fan for inducing air movement within the building; flowing air directly through the at least one fan and into the building; continuously operating the at least one fan; sensing at least one internal environmental parameter; and varying a speed of the at least one fan according to the at least one sensed internal environmental parameter; and admitting external air into the internal environment and regulating flow of the external air in response to the at least one sensed internal environmental parameter.
- 7. A method of controlling the internal environment of a building for human occupancy, the method comprising:providing at least one air handling unit including at least one fan for inducing air movement within the building; flowing air directly through the at least one fan and into the building; continuously operating the at least one fan; sensing at least one internal environmental parameter; varying a speed of the at least one fan according to the at least one sensed internal environmental parameter; and selecting a maximum power level and a minimum power level for input to the at least one fan, wherein the maximum power level is a reduced power level, and continually operating the at least one fan at a speed between the selected maximum and minimum power levels.
- 8. A method of controlling the internal environment of a building for human occupancy, the method comprising:providing at least one air handling unit including at least one supply fan for inducing air movement within an environment of the building; selecting a maximum speed and a minimum speed for the at least one supply fan; continuously operating the at least one supply fan between the selected maximum and minimum speeds; flowing air directly through the at least one fan and into the building; selecting a first internal environmental parameter which is to be maintained within the building; monitoring an instantaneous value of the selected first internal environmental parameter; varying the speed of the at least one supply fan in response to the monitored instantaneous value of the selected first internal environmental parameter; providing at least one return fan for removing air from the internal environment of the building; and diverting at least a portion of the air removed from the internal environment back to the at least one supply fan to be reintroduced to the internal environment of the building.
- 9. The method according to claim 8, further comprising:selecting a first external environmental parameter; monitoring an instantaneous value of the selected first external environmental parameter; and controlling an amount of air diverted back to the at least one supply fan in response to said instantaneous value of the selected first external environmental parameter.
- 10. The method according to claim 9, wherein controlling the amount of air diverted back to the at least one supply fan includes varying the speed of the at least one return fan.
