Definitions

• the invention relates to a protective suit system according to the preamble of claim 1.
• Pilots e.g. Modern fighter planes, astronauts, but also drivers of armored vehicles, are particularly exposed to extreme thermal loads, with pilots and astronauts adding high acceleration forces. Protective equipment that takes account of the conditions of use is therefore necessary for the safe execution of the operational tasks.
• the breathing gas required is provided by a mixture of oxygen and cabin air via breathing masks to provide the pilots, in particular military aircraft or even astronauts.
• the oxygen is carried in the liquid or gaseous state.
• the mixing ratio of oxygen and cabin air required to form the breathing gas is determined by breathing regulators as a function of the cabin pressure level.
• Efforts are also known to remove unsatisfactory heat dissipation from contact surfaces between the grains, e.g. by pilots (seat and backrest), only to be replaced by a flow of liquid in pipelines using air flow. Many advantages of air cooling have been abandoned.

Heat transfer and thus the direction of the heat flows depends on The thermodynamic state of the flowing fluid and the ambient conditions and is regulated by the fluid for microclimatising the body of the wearer. There is no direct interaction between the body and the environment, since the air flow forms a microclimate close to the body that separates the body and the environment.
