Classification: CPC B  Y | IPC B

Claim 1:
2. The system according to claim 1, wherein the first and second switchable heat sources are each in thermal communication with a fluid within the thermodynamic cycling system and the controller is operable to actuate at least one control valve which is operable to selectively switch the fluid in thermal communication with one of the switchable heat sources into thermal communication with the compressor in the thermodynamic cycling system, wherein the controller is operable to actuate the at least one control valve to switch one of the first and second switchable heat sources into thermal communication with the thermodynamic cycling system when a temperature differential is detected between a fluid entering the compressor in the thermodynamic cycling system and the switchable heat source, the temperature differential being such that the compressor is operable to upgrade low grade heat from the switchable heat source to a higher grade heat upon operation of the compressor.
