AI Technical Summary

Benefits of technology

This solution allows for precise airflow adjustment to address comfort issues and reduces noise and drafts by enabling gradual motor speed changes, improving system performance and user comfort.

Problems solved by technology

One problem with this arrangement, however, is that once a tap and speed are selected, the installer has no control of the speed.
For example, in the case of heating, the temperature rise of air leaving a heat pump may be less than that leaving a furnace, thereby reducing comfort.
As another example, in the case of cooling, an improperly configured HVAC system may lead to low or high humidity levels, thereby reducing comfort.
The flow of air leaving an air conditioner may control humidity levels, where slowing airflow may increase dehumidification.
Fixed speed PSC motors also might cause ductwork and air noise due to the rapid startup of the motor.

Embodiment Construction

[0028]One or more embodiments or implementations are hereinafter described in conjunction with the drawings, where like reference numerals are used to refer to like elements throughout, and where the various features are not necessarily drawn to scale.

[0029]With reference to FIG. 1, a block diagram of an HVAC system 100 according to aspects of the exemplary embodiment is provided. The HVAC system 100 suitably belongs to one or more of the following groups of HVAC systems: residential split and package systems; natural gas, propane, and oil heat furnace systems; dual fuel systems; hot water coil and geothermal air handler systems; and the like.

[0030]As will be seen, the HVAC system 100 provides for manual adjustment of blower motor speed and / or torque advantageously allowing higher precision airflow selection, thereby giving the installer or maintenance technician the ability to compensate for system performance problems. For example, as noted above, the installer or maintenance tech...

Abstract

A heating, ventilation and air conditioning (HVAC) system is provided. The system includes an integrated motor including a plurality of operating speeds and an input for selecting one of the plurality of operating speeds. The system further includes a system controller and an adjustment module. The adjustment module includes a plurality of operating modes each associated with one of the plurality of operating speeds and the ability to manually vary associations between the plurality of operating modes and the plurality of operating speeds. The adjustment module selects one of the plurality of operating modes on the basis of control commands received from the system controller and setting programmed or manually entered into and stored in the adjustment module and controls the integrated motor according to the operating speed associated with the selected operating mode.

Description

[0001]This is a divisional application of copending U.S. application Ser. No. 13 / 352,515, filed Jan. 18, 2012, which claims the benefit of U.S. Provisional Application No. 61 / 433,701, filed Jan. 18, 2011, both of which are incorporated herein by reference in their entirety.BACKGROUND [0002]The present exemplary embodiments relate generally to heating and cooling. They find particular application in conjunction with heating, ventilation, and air conditioning (HVAC) systems, and will be described with particular reference thereto. However, it is to be appreciated that the present exemplary embodiments are also amenable to other like applications.[0003]By way of background, many residential and small commercial forced air HVAC systems employ Permanent Split Capacitor (PSC) motors and / or an Electronically Commutated Motors (ECMs) to drive blowers. These motors generally include selectable speed taps for indoor speed control. Speed is determined by characteristics of the motor and system...
