Abstract
A method for cooling a refuge chamber (100) with an emergency cooler (10) in an emergency situation includes cooling of a refrigerating agent (22) in a cold accumulator (20) with a cooling device (30) and detecting an emergency situation. Cold being stored in the refrigerating agent (22) of the cold accumulator (20) is released into the refuge chamber (100)—the refrigerating agent (22) of the cold accumulator (20) is exposed for heat transfer with the refuge chamber (100).
Claims20
A method for cooling a refuge chamber by means of an emergency cooler in an emergency situation, the method comprising the steps of:
- cooling a refrigerating agent in a cold accumulator with a cooling device;
- detecting an emergency situation;
- and
- releasing cold being stored in the refrigerating agent of the cold accumulator into the refuge chamber.
An emergency cooler for cooling a refuge chamber in an emergency situation, the emergency cooler comprising:
- a cold accumulator;
- a refrigerating agent arranged in the cold accumulator;
- a cooling device for cooling the refrigerating agent;
- and
- a releasing device for releasing the cold being stored in the refrigerating agent of the cold accumulator into the refuge chamber.
A refuge chamber cooling system comprising:
- a cold accumulator;
- a refrigerating agent arranged in the cold accumulator;
- a powered cooling device for cooling the refrigerating agent;
- a heat transfer arrangement for heat exchange between refuge chamber and the refrigerating agent;
- and
- a detection device detecting an emergency situation to activate the heat transfer arrangement for heat exchange between refuge chamber and the refrigerating agent.
