Description
Technical Field
The utility model relates to the technical field of heating ventilation and air conditioning, in particular to a heating ventilation and air conditioning control device for multiple target areas.
Background
Prior art embodiments of hvac control systems are typically capable of switching on and off the heat/cold source while increasing or decreasing the air circulator fan speed through 2 to 3 (and occasionally more) steps to achieve the desired indoor conditioning required by the user-programmed thermostat.
In prior art multi-zone systems, dampers are used to partially shut down the zones where the system deems it necessary to reduce air flow when the regulation requirements vary between zones.
Because of the need to preserve the ability of the system to vent excess air, the system cannot fully close the damper, and therefore undesirable conditions may be transferred to areas where it is not needed, and because the ability of the ductwork to handle excess air flow is reduced when one or more of the dampers are partially closed, the air pressure in the system typically increases dramatically.
The increase in pressure in the ductwork then increases the air flow through the remaining open dampers, resulting in significant poor turndown performance and noise, and the number of zones in such systems is limited due to the increased amplification of defects after each zone.
In addition, the overall energy efficiency of the multi-zone heating and cooling system may be significantly reduced when there is poor regulation and noise.

The area 4 labeled area N in fig. 1 is provided for the purpose of illustrating that the number of zones is not limited by the capacity of the multi-target zone adjustable speed hvac control, but rather by the configuration and intended application of the hvac system. It will be appreciated that the system may be equipped with fifth, sixth, seventh or more zones, each equipped with dampers and thermostats to meet application requirements, and each providing zone adjustment similar to that described above, without departing from the spirit of the utility model.
