A variable density airship lift chamber system for airships provides more efficient lift control. The airship lift chamber system includes at least one lift chamber filled with lift gas and configured to provide lifting force, a heat exchanger configured to heat the lift gas in the at least one lift chamber, a compressor unit configured to withdraw the lift gas from the lift chamber and to compress the withdrawn lift gas, a pressure tank configured to store the withdrawn compressed lift gas from the compressor unit, a refrigeration orifice formed in the lift chamber, and a valve that connects the pressure tank to lift chamber through the refrigeration orifice. The airship lift chamber system controls density of the lift gas in the lift chamber by heating the gas while removing the gas from the lift chamber and by supplying gas into the lift chamber.

Container 12 is a cabin of a gas balloon, Container 12 has Main Body 121, which is an airtight container for accommodating Crew Member H1 and is filled with Air 122, Heat Transfer Member 125 made of a material that has a high thermal conductivity such as aluminum and that covers the inside of Main Body 121 and is partially in contact with Heat Absorber Holder 123, Heat Absorber Holder 123 that is a container made of a material that has a high thermal conductivity, such as aluminum, and is located outside of Main Body 121, and Heat Absorber 124 contained in Heat Absorber Holder 123. Heat generated by Crew Member H1 is transferred via Air 122 to Heat Transfer Member 125 and then to Heat Absorber Holder 123. Heat Absorber 124 absorbs heat from Heat Absorber Holder 123 as heat of vaporization and changes from a liquid to a gas.
