underground emergency system

Underground emergency facility is a confined space providing life support for people who has no time for evacuation. This emergency facility, externally, resist high temperature gas and isolate   from toxic gas, and internally supply oxygen, food, water, and remove harmful gas, creating the basic condition for living and earning time for emergency rescue, and also guiding outside rescue by inner setted communication monitoring equipment.

Advantages and disadvantage of Mainstream refrigeration methods

	Technology  readiness  level	toxicity	Influence  of humidity	Cost	Energy  or energy  free	others
Ice  storage  refrigeration	High	No	Add	High	Yes	Troublesome to maintain,  energy consumption large.  Easy to cause explosion  when  power off gas density  exceeds over normal  state
Liquid CO2	High	yes	No	High	Yes	Regular replace ment,  large  volume of storage  equipment, storage  temperature  low, refrigeration  effect is heavily reduced when temperature higher  than 31.1°C
NH4NO3  heat of    solution	High	yes	No	Low	No	2-year replacement,  possible explosion  when heated
Energy  free phase  change air  conditioner	Low,  new type  not widely  promoted	No	No	Low	No	Energy intensity reaches 335MJ/m3,  maintenance  free, no risk of explosion, stable  performance, long life

mainstream refregeration methods

To prevent external CO and other toxic gas infiltrating into the chamber, airtight and positive pressure structure is applied in the refuge chamber and lifesaving capsule. Temperature and humidity will gradually rise when people get into the airtight and positive pressure structure chamber. So, to meet the standard of temperature lower than 35°C and humidity less than 85%, we should have to cool and dehumidify refuge chamber and lifesaving capsule. The current refrigeration methods are mainly: ice storage refrigeration, high pressure gas expansion refrigeration( generally liquid CO2), NH4NO3 heat of solution and phase change material(with our company energy free phase change air conditioner ).
