Compressor operation management in air conditioners

摘要

In various implementations, compressor operation in an air conditioner may be managed by maintaining oil viscosity, a temperature differential, compressor sump temperature, and/or suction pressure. Properties of the air conditioner or portions thereof, such as the compressor, may be determined. To manage compressor operations, operation(s) of the air conditioner may be adjusted based on one or more of the determined properties.

1. A method of managing air conditioner operations, the method comprising:
determining a compressor sump temperature of an air conditioner; determining a suction pressure of the air conditioner; determining suction saturated temperature based at least partially on the determined suction pressure; determining a temperature differential based on the difference between the determined compressor sump temperature and the determined suction saturated temperature; retrieving oil viscosity associations, wherein the oil viscosity associations includes associations between oil viscosities, suction pressures, and compressor sump temperatures; determining a minimum temperature differential based at least partially on the suction pressure and the retrieved oil viscosity associations; and managing one or more operations of the air conditioner based at least partially on the determined minimum temperature differential and the determined temperature differential.
