Abstract
An apparatus and a method is provided for varying high side pressure in a transcritical vapor compression cycle by means of variable volume element(s) connected to a flow circuit thereof. A variable volume element having a compartment is connected to and communicates with the high side to permit entry of refrigerant into the compartment. A movable partition defines at least one side of the compartment and is displaceable between first and second positions respectively defining first and second volumes of refrigerant within the compartment.
