Problems solved by technology

However, rescue efforts may take many hours or days
Typically, shelters have limited life support systems for maintaining personnel in regulated areas and may not effectively handle CO 2 and accumulation of CO
Additionally, limited life support systems are not compatible with evolving safety standards
in addition, some existing life support systems rely on power systems that can be cumbersome and unsafe to use in an emergency environment

Embodiment Construction

[0033] There is a need to provide shelters in which breathable air can be maintained free of CO, purified of CO 2 and is cooled. This shelter allows workers to stay while avoiding oxygen (O 2 ) insufficient and / or toxic gases until they can be brought to safety. While the invention may be used in many environments where these events are encountered, embodiments of the invention will be described in the context of an underground mine.

[0034] The life support system 1 of the present invention provides shelter for miners in emergency situations. The life support system 1 of the present invention comprises a mine shelter housing 2 and a life support element 4 associated with the mine shelter housing 2 . Life support elements 4 include O 2 Supplementary system 12, CO 2 Purification system 14 (including blower assembly 10 ) and self-operating cooling system 16 .

[0035] refer to Figures 1 to 6 , the mine shelter housing 2 may comprise various structures and may be made of...

Abstract

A life support system includes a refuge housing and a cooling system. The cooling system, which has a supply of liquefied gas and a cooling circuit, is operatively associated with the refuge housing. The supply of liquefied gas is operatively associated with the cooling circuit that contains a heat exchanger, a fan motor and a fan operatively associated with the fan motor. A conduit connects the heat exchanger to the fan motor that is driven by waste gas generated through a phase change of the liquefied gas in the heat exchanger.

Description

technical field [0001] The present invention relates to life support systems. In particular, the invention is for a life support system comprising a self-operating cooling system for shelters in emergency situations. Background technique [0002] Unexpected explosions, accidents, and other emergencies can occur in a variety of industrial environments, such as mines, petroleum refineries, chemical plants, sugar refineries, and more. In this case, due to the lack of oxygen and the presence of carbon monoxide (CO) and carbon dioxide (CO 2 ), the ambient air may suddenly become unbreathable. Refuge A regulated area that provides relative protection while awaiting rescue. However, rescue efforts may take many hours or days. Typically, shelters have limited life support systems for maintaining personnel in regulated areas and may not effectively handle CO 2 and CO accumulation. Additionally, limited life support systems are not compatible with evolving safety standards. Fur...
