Abstract

A heating, ventilation, and air-conditioning (“HVAC”) system. The HVAC system may include a refrigeration circuit and a blower system. The refrigeration circuit may include a compressor, an outdoor heat exchanger, an expansion device, and an indoor heat exchanger. The blower system may include a first direct-drive blower and a second direct-drive blower. The first direct-drive blower may flow air over the indoor heat exchanger. The second direct-drive blower may flow air over the indoor heat exchanger and the second direct-drive blower may operable and positionable relative to the indoor heat exchanger independently from the first direct-drive blower.

Claims (35)

1 . A method of operating an HVAC system, the method comprising:

identifying an input temperature for a room;

measuring a temperature of the room;

determining a demand on the HVAC system based on the input temperature and the measured temperature of the room; and

operating one or both of a first direct-drive blower of the HVAC system and a second direct-drive blower of the HVAC system independently to flow air over an indoor heat exchanger of the HVAC system based on the demand on the HVAC system; and

positioning the first direct-drive blower, the second direct-drive blower, and an indoor heat exchanger of the HVAC system such that a ratio of a distance between midlines of widths of the first direct-drive blower and the second direct-drive blower and a distance between a central axis of either the first direct-drive blower or the second direct-drive blower and a vertical midplane of the indoor heat exchanger has a range of approximately 0.5 to approximately 4.

2 . The method of claim 1 , further comprising positioning the first direct-drive blower and the second direct-drive blower relative to the indoor heat exchanger and independently of each other.

3 . The method of claim 1 , further comprising positioning the first direct-drive blower and the second direct-drive blower such that a ratio of a distance between midlines of widths of the first direct-drive blower and the second direct-drive blower and a width of either the first direct-drive blower or the second direct-drive blower has a range of approximately 0.5 to approximately 5.5.

4 . The method of claim 1 , further comprising positioning the first direct-drive blower and the second direct-drive blower such that a ratio of a distance between midlines of widths of the first direct-drive blower and the second direct-drive blower and a diameter of either the first direct-drive blower or the second direct-drive blower has a range of approximately 0.5 to approximately 4.

5 . The method of claim 1 , wherein a maximum airflow rate of the first direct-drive blower is different than a maximum airflow rate of the second direct-drive blower.

6 . The method of claim 1 , further comprising positioning the first direct-drive blower independently of the second direct-drive blower.

7 . The method of claim 1 , wherein positioning the first direct-drive blower independently of the second direct-drive blower comprises positioning the first direct-drive blower and the second direct-drive blower such that the first direct-drive blower and the second direct-drive blower are at least one of positioned within a specified range of distances with respect to the indoor heat exchanger or with respect to each other.

8 . A method of operating an HVAC system, the method comprising:

identifying an input temperature for a room;

measuring a temperature of the room;

determining a demand on the HVAC system based on the input temperature and the measured temperature of the room;

positioning the first direct-drive blower and the second direct-drive blower such that a ratio of a distance between midlines of widths of the first direct-drive blower and the second direct-drive blower and a width of either the first direct-drive blower or the second direct-drive blower has a range of approximately 0.5 to approximately 5.5.

9 . The method of claim 8 , further comprising positioning the first direct-drive blower and the second direct-drive blower relative to the indoor heat exchanger and independently of each other.

10 . The method of claim 8 , further comprising positioning the first direct-drive blower, the second direct-drive blower, and an indoor heat exchanger of the HVAC system such that a ratio of a distance between midlines of widths of the first direct-drive blower and the second direct-drive blower and a distance between a central axis of either the first direct-drive blower or the second direct-drive blower and a vertical midplane of the indoor heat exchanger has a range of approximately 0.5 to approximately 4.

11 . The method of claim 8 , further comprising positioning the first direct-drive blower and the second direct-drive blower such that a ratio of a distance between midlines of widths of the first direct-drive blower and the second direct-drive blower and a diameter of either the first direct-drive blower or the second direct-drive blower has a range of approximately 0.5 to approximately 4.

12 . The method of claim 8 , wherein a maximum airflow rate of the first direct-drive blower is different than a maximum airflow rate of the second direct-drive blower.

13 . The method of claim 1 , further comprising positioning the first direct-drive blower independently of the second direct-drive blower.

14 . The method of claim 8 , wherein positioning the first direct-drive blower independently of the second direct-drive blower comprises positioning the first direct-drive blower and the second direct-drive blower such that the first direct-drive blower and the second direct-drive blower are at least one of positioned within a specified range of distances with respect to the indoor heat exchanger or with respect to each other.

15 . A method of operating an HVAC system, the method comprising:

identifying an input temperature for a room;

measuring a temperature of the room;

determining a demand on the HVAC system based on the input temperature and the measured temperature of the room;

positioning the first direct-drive blower and the second direct-drive blower such that a ratio of a distance between midlines of widths of the first direct-drive blower and the second direct-drive blower and a diameter of either the first direct-drive blower or the second direct-drive blower has a range of approximately 0.5 to approximately 4.

16 . The method of claim 15 , further comprising positioning the first direct-drive blower and the second direct-drive blower relative to the indoor heat exchanger and independently of each other.

17 . The method of claim 15 , further comprising positioning the first direct-drive blower, the second direct-drive blower, and an indoor heat exchanger of the HVAC system such that a ratio of a distance between midlines of widths of the first direct-drive blower and the second direct-drive blower and a distance between a central axis of either the first direct-drive blower or the second direct-drive blower and a vertical midplane of the indoor heat exchanger has a range of approximately 0.5 to approximately 4.

18 . The method of claim 15 , further comprising positioning the first direct-drive blower and the second direct-drive blower such that a ratio of a distance between midlines of widths of the first direct-drive blower and the second direct-drive blower and a width of either the first direct-drive blower or the second direct-drive blower has a range of approximately 0.5 to approximately 5.5.

19 . The method of claim 15 , wherein a maximum airflow rate of the first direct-drive blower is different than a maximum airflow rate of the second direct-drive blower.

20 . The method of claim 15 , wherein positioning the first direct-drive blower independently of the second direct-drive blower comprises positioning the first direct-drive blower and the second direct-drive blower such that the first direct-drive blower and the second direct-drive blower are at least one of positioned within a specified range of distances with respect to the indoor heat exchanger or with respect to each other.
