more controllers 22 if the energy from the actual power source is not more expensive i e is less expensive than energy from the assumed power source may alter the operating parameter s of the climate system 20 to increase the power consumption of the compressor 26 to improve performance the one or more controllers 22 for example may lower the target evaporator temperature decrease its response time increase the limit on compressor speed and or increase the limit on compressor power again the amount by which the operating parameters are altered may be determined via testing simulation etc and balance power consumption with performance in other embodiments the one or more controllers 22 may access a look up table having values for the climate system operating parameters mapped with the potential sources of energy for the compressor 26 before selecting the operating parameters for the climate system 20 the one or more controllers 22 may determine in a known fashion the energy source for the compressor 26 and retrieve one or more operating parameters associated with that source from the look up table in such embodiments default operating parameters may not be necessary the one or more controllers 22 may periodically determine the energy source for the compressor 26 and retrieve alter the appropriate operating parameters etc other scenarios are also possible as apparent to those of ordinary skill the algorithms disclosed herein may be deliverable to a processing device in many forms including but not limited to i information permanently stored on non writable storage media such as rom devices and ii information alterably stored on writeable storage media such as floppy disks magnetic tapes cds ram devices and other magnetic and optical media the algorithms may also.
