METHOD AND DEVICE FOR AMBIENT AIR COOLING BY CLOSED COOLING CYCLE Russian patent published in 2004 - IPC

FIELD: cooling plants, particularly for land-based, space and underwater plants.

SUBSTANCE: method involves compressing low-pressure gaseous working fluid up to high pressure, adiabatic expanding gaseous working fluid up to low pressure; chemically combining low-pressure gaseous working fluid in the form of hydrogen gas with nickel hydroxide NiOOH or with silver oxide AgO, which results in reactive products obtaining; simultaneously impacting electric current to reactive products, which results in high-pressure gaseous medium obtaining; adiabatic expanding high-pressure gaseous medium up to low pressure. Electric current is produced during reacting of nickel hydroxide NiOOH or silver oxide AgO with low-pressure hydrogen. Device for cooling ambient air includes heat-exchanger, high-pressure and low-pressure pipelines. Device also includes at least two nickel-hydrogen batteries, high-pressure and low-pressure receivers, charging/discharging unit, switch, contactor, electric current source, automatic unit and turbine with generator. Charging/discharging unit is connected through switch with current source and through contactor with nickel-hydrogen battery bases. Output of control signal of charging/discharging unit is connected with automatic unit input, which in turn is connected to contactor by the first input thereof. High-pressure and low-pressure pipelines are joined by manifold into which valves are installed. One valve is located between the first nickel-hydrogen battery body and low-pressure pipeline. The second valve is arranged between the first nickel-hydrogen battery body and high-pressure manifold. The third valve is installed between the second nickel-hydrogen battery body and low-pressure manifold. The forth valve is located between high-pressure manifold and the second nickel-hydrogen battery body. The second, the third, the forth and the fifth automatic unit outputs are connected to inlets of above valves. High-pressure pipeline has seriously installed high-pressure check valve, high-pressure receiver, electric valve, reducer and turbine. Low-pressure pipeline is joined to turbine outlet. Heat-exchanger, low-pressure receiver and low-pressure check valve are sequentially installed on low-pressure pipeline.

EFFECT: increased efficiency and maintainability.
