Refrigerant System With Stator Heater
First Claim
Patent Images
1. A refrigerant system adapted to reduce refrigerant migration therein, the system comprising:
- a compressor having a motor with motor windings, the motor windings responsive to control signals to selectively generate heat in a manner that does not turn the motor; and
a controller that selectively energizes the motor windings to generate heat based on at least one of a monitored temperature or pressure to warm the compressor.

Abstract
A refrigerant system adapted to reduce refrigerant migration therein includes a compressor and a controller. The compressor has a motor with motor windings. The motor windings are responsive to control signals to selectively generate heat in a manner that does not turn the motor. The controller selectively energizes the motor windings to generate heat based on at least one of a monitored temperature or pressure to warm the compressor.

16. A method of reducing refrigerant migration to a compressor comprising:
-
providing compressor having a motor with motor windings responsive to control signals to selectively generate heat in a manner that does not turn the motor; monitoring at least one of a refrigerant system temperature or pressure; and controlling the motor windings to selectively generate heat based on at least one of the monitored temperature or pressure to reduce refrigerant migration to the compressor. - View Dependent Claims (17, 18, 19, 20)
