Patent ID: 7032400

Claim:
A refrigeration merchandiser comprising: at least one surface at least partially defining an environmental space adapted to accommodate a commodity; a linear compressor including a piston, a condenser, an expansion device, and an evaporator in fluid communication, the evaporator being in thermal communication with the environmental space to influence the temperature of the environmental space; a frame supporting the at least one surface, the linear compressor, the condenser, the expansion device, and the evaporator; and a controller coupled to the linear compressor, the controller comprising a sensor configured to sense a parameter representative of an operating condition associated with the merchandiser, and wherein the controller is operable to control the linear compressor based at least in part on the sensed parameter, and further wherein the controller is operable to control the linear compressor by being further operable to control the stroke of the piston based at least in part on the sensed parameter.
