Abstract
In various implementations, frost in a vapor compression system may be controlled. A property of a fan may be determined. A determination may be made whether a frost event and/or a nonfrost event has occurred based at least partially on the determined fan property.
Claims20
A method comprising:
- determining one or more fan properties of a vapor compression system;
- and
- determining if a frost event has occurred based at least partially on at least one of the determined fan properties.
A vapor compression system comprising:
- a fan;
- a sensor that measures one or more fan properties;
- and
- a management module that determines whether a frost event has occurred at least partially based on one or more of the measured fan properties.

An article comprising machine-readable medium storing instructions for managing a vapor compression system, the instructions operable to cause data processing apparatus to perform operations comprising:
- determining one or more fan properties of a vapor compression system;
- determining if a frost event has occurred based at least partially on at least one of the determined fan properties;
- and
- transmitting a signal to allow one or more defrost operations to occur if a frost event has occurred, wherein a defrost operation is configured to reduce accumulation of frost on at least a portion of the vapor compression system.
