Abstract
Official abstract text for this publication.
Methods and system for operating a heat pump in different operating modes and providing a predictable heat pump response when the heat pump is transitioned between the different operating modes are presented. In one example, a controller that includes executable instructions for providing a bumpless compressor command for operating the heat pump is disclosed.
First claim
Opening claim text (preview).
The invention claimed is: 1. A heat pump method, comprising: commanding a compressor to provide a desired evaporator temperature in response to output of an evaporator temperature controller and output of a refrigerant pressure controller in a first heat pump operating mode; commanding the compressor to provide a desired heater core temperature in response to output of a heater core temperature controller and output of the refrigerant pressure controller in a second heat pump operating mode; and adjusting integrator gains in response to transitioning from the first heat pump operating mode to the second heat pump operating mode. 2. The method of claim 1 , where the first heat pump operating mode is a cooling mode, and where the second heat pump mode is a heating mode. 3. The method of claim 1 , further comprising adding a cooling feed forward command to the output of the evaporator temperature controller in the first heat pump operating mode. 4. The method of claim 1 , further comprising adding a heating feed forward command to the output of the heater core temperature controller in the second heat pump operating mode. 5. The method of claim 1 , further comprising switching commanding the compressor to provide the desired evaporator temperature to commanding the compressor to provide the desired heater core temperature in response to a request to change a heat pump operating mode. 6. A heat pump method, comprising: commanding a compressor to provide a desired evaporator temperature in response to output of an evaporator temperature controller and output of a refrigerant pressure controller in a first heat pump operating mode; commanding the compressor to provide a desired heater core temperature in response to output of a heater core temperature controller and output of the refrigerant pressure controller in a second heat pump operating mode; and resetting an integrator output to zero in response to transitioning from the first heat pump operating mode to the second heat pump operating mode.
