Abstract
A warewash machine includes a chamber for receiving wares, the chamber having at least one wash zone. A refrigerant circuit includes multiple condensers including a condenser to deliver refrigerant heat to incoming water that is being delivered into the machine. A primary flow path for incoming water passes through a waste heat recovery unit and a secondary flow path for incoming water bypasses the waste heat recovery unit. A valve is provided for selectively controlling whether refrigerant flows along the primary flow path or the secondary flow path based upon a subcooled condition of refrigerant in the refrigerant circuit.
