A device for compressing gas by using solar energy or ambient heat comprises two high-pressure heat exchangers (1, 2). One high-pressure heat exchanger (1) serves as a solar collector and the other high-pressure heat exchanger (2) serves as a cooler. Both high-pressure heat exchangers (1, 2) are interconnected via pipes, valves (8, 31, 32, 33) and a pneumatic cylinder (5). A pressure difference resulting from different temperature levels of both high-pressure heat exchangers (1, 2) displaces the pneumatic cylinder (5), whereby the pneumatic cylinder (5) acts upon a compressor (40). In order to utilize the compression heat, the compressed gas is led through the primary side of the high-pressure heat exchanger (1) that functions as a collector. The stored compressed air is used for driving a turbine (12). The gas that is expanded by a turbine (12) cools down rapidly and is led over the primary side of the high-pressure heat exchanger (2) that functions as a cooler. A high-pressure heat exchanger system of the aforementioned type is suited for driving automobiles or as a stationary installation, e.g. on the roofs of buildings.
