Abstract
A refrigeration merchandiser including at least one surface at least partially defining an environmental space adapted to accommodate a commodity. The merchandiser includes a linear compressor, a condenser, an expansion device, and an evaporator. The linear compressor, which can be a free-piston linear compressor having dual-opposing pistons, the condenser, the expansion valve and the evaporator are all in fluid communication. The evaporator is in thermal communication with the environmental space to influence the temperature of the environmental space. A merchandiser also includes a frame supporting the at least one surface, the linear compressor, the condenser, the expansion device, and the evaporator.
