Abstract
A refrigeration system including a condenser; a (single) linear compressor that is activated and deactivated by a pulse width modulation switching device; a pulse width modulation refrigerant flow switch; at least two evaporators operably connected in parallel with one another with at least one evaporator associated with the refrigerator compartment that operates at a first refrigerant fluid pressure and with at least one other evaporator associated with the freezer compartment that operates at a second refrigerant fluid pressure; and a plurality of refrigerant fluid conduits operably connecting the condenser, the linear compressor and the evaporators into a refrigerant fluid flow circuit and such that the evaporators are capable of running simultaneously at different pressure levels and refrigerant flows from the evaporators, to the pulse width modulation refrigerant flow switch and through the pulse width modulation refrigerant flow switch.
