Device for providing thermal energy to gas environment in pneumatic engine, has low pressure inlet and high pressure outlet, and heater collecting heat energy in its environment and supplying heat energy to secondary circuit

摘要

The device has a low pressure inlet and a high pressure outlet. A heater collects heat energy in its environment and supplies the heat energy to a secondary circuit of gas heating elements. A gas flow controller is provided in the secondary circuit for controlling a pneumatic engine associated with the thermal energy providing device. A tank is filled by outgoing gas of the pneumatic engine, and temperature of the tank is lowered.
