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 highpressure 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 …
