Cooling system, compressor system and solar tracking device

A cooling system, including:

• a refrigeration arrangement, including:
• at least one cooling chamber configured to receive one or more objects to be cooled;
• at least one rotary compressor for pressurising at least one refrigerant;
• at least one condenser which is arranged downstream from the rotary compressor, with respect to a direction of flow of the refrigerant, and configured to receive the pressurised refrigerant, wherein the condenser is configured to dissipate heat from the refrigerant to an ambient which is arranged at least partially outside of the cooling chamber;
• at least one expander arranged downstream from the condenser and configured to expand the refrigerant;
• and
• at least one evaporator which is arranged downstream from the expander and operatively connected to the cooling chamber to absorb heat from the cooling chamber to the refrigerant;
• at least one Stirling motor having at least one rotatable driveshaft which is operatively connected to the rotary compressor and configured to rotatably drive the rotary compressor;
• at least one solar energy capturing device which is configured to capture solar energy;
• and
• at least one solar tracking device configured to maximize the degree of solar energy which can be captured by the solar energy capturing device, wherein the solar tracking device is driven only mechanically;
• wherein the Stirling motor includes at least one expansion space, in which at least one working medium is arrangeable and expandable, a first piston which is movably arranged at least partially in the expansion space, at least one compression space, in which the working medium is arrangeable and compressible by a second piston which is operatively coupled with the first piston via the driveshaft and movably arranged at least partially in the compression space, wherein the Stirling motor is configured to cooperate with at least one heat source such that the working medium is heatable in the expansion space by the heat source to expand the working medium and drive the first piston to rotatably drive the driveshaft.
