Influence of ribbing of condenser part of loop thermosyphon on cooling effect

Place accumulation of elements in all systems is objectively necessary.Similarly, in the RES energy systems is their role is irreplaceable. The renewable energy systems can use different types of storage: electrochemical batteries, supercapacitors, superconducting units, rotary, pneumatic and others. ...

Staničné elektrochemické akumulátory pre OZE

Miesto akumulačných prvkov vo všetkých systémoch je objektívne nevyhnutná. Rovnako aj v energetických systémoch OZE je ich úloha nenahraditeľná. V systémoch OZE je možné použiť rôzne typy zásobníkov: elektrochemické akumulátory, superkondenzátory, supravodičové jednotky, rotačné, tlakovzdušné a iné. Tieto ...
