BLOWER PROPERTIES USED FOR USER WARNING
A climate control unit (e.g., for a residential building) may include a heat exchanger, a blower that circulates air from a return duct, across the heat exchanger, to a supply duct, and a filter that cleans the air before entering the heat exchanger. The effectiveness and/or efficiency of the filter may decrease as the filter collects particles. The climate control unit may include a controller configured to set a baseline measurement according to measurements of a blower property after a reset event. The controller may be configured to measure a deviation of the blower property from the baseline measurement of the blower property. The controller may be configured to generate a status notification in response to the deviation satisfying a threshold. The status notification may indicate that the filter should be changed.
1 . A climate control unit comprising:
a heat exchanger;
a blower that circulates air from an intake or return duct, across the heat exchanger, to a supply duct;
a filter that cleans air before entering the heat exchanger; and
a controller configured to:
set a baseline measurement of a blower property according to measurements of the blower property after a reset event;
measure a deviation of the blower property from the baseline measurement of the blower property; and
generate a status notification in response to the deviation satisfying a threshold.
2 . The climate control unit of claim 1 , wherein the reset event is in response to a user input to a button on the controller, a command from an application that displays the status notification to a user, or a detected filter change.
3 . The climate control unit of claim 1 , wherein the blower is configured with one or more preset operating programs and the deviation is measured based on operation during one of the preset operating programs.
4 . The climate control unit of claim 3 , wherein the controller controls the blower to move a preset volume of air during the one preset operating program.
5 . The climate control unit of claim 1 , wherein the blower property is one of: blower wattage, pulse width of a blower control signal, blower current, or blower speed.
6 . The climate control unit of claim 1 , wherein the threshold is a percentage of the baseline measurement or a number of units of the blower property.
7 . The climate control unit of claim 1 , further comprising a wireless modem configured to transmit the status notification to a remote user device associated with the climate control unit.
8 . The climate control unit of claim 7 , wherein the status notification is a text message, email, or notification for an application on the remote user device.
9 . The climate control unit of claim 1 , further comprising a display configured to display the status notification.
10 . The climate control unit of claim 1 , wherein the status notification indicates that the filter should be changed.
11 . A method of controlling a climate control system including a blower, comprising:
setting a baseline measurement of a blower property according to measurements of the blower property after a reset event;
measuring a deviation of the blower property from the baseline measurement of the blower property; and
generating a status notification in response to the deviation satisfying a threshold.
12 . The method of claim 11 , wherein the reset event is in response to a user input to a button on a controller, a command from an application that displays the status notification to a user, or a detected filter change.
13 . The method of claim 11 , wherein the blower is configured with one or more preset operating programs, and wherein measuring the deviation is based on operation during a preset operating program.
14 . The method of claim 13 , wherein the blower is configured to to move a preset volume of air during the one or more preset operating programs.
15 . The method of claim 11 , wherein the blower property is one of: blower wattage, pulse width of a blower control signal, blower current, or blower speed.
16 . The method of claim 11 , further comprising transmitting the status notification to a remote user device associated with the climate control system.
17 . The method of claim 11 , further comprising displaying the status notification on a display of a climate control system controller.
18 . The method of claim 11 , wherein the status notification indicates that a filter should be changed.
19 . A controller for a climate control system, comprising:
a memory storing computer-executable instructions;
a processor ocmmunicatively coupled to the memory to execute the instructions, wherein the processor is configured to:
set a baseline measurement of a blower property according to measurements of the blower property after a reset event;
measure a deviation of a blower property from a baseline measurement of the blower property; and
generate a status notification in response to the deviation satisfying a threshold.
20 . The controller of claim 19 , wherein the reset event is in response to a user input to a button on the controller, a command from an application that displays the status notification to a user, or a detected filter change.
