Abstract
Abstract A wind-powered energy production and storing system comprises a wind rotor (1) in driving engagement with a power generator via transmission means, to which is also connected a heat pump for operation of at least one heat exchanger unit. The wind rotor (1) is designed as a wind wheel having a rim in direct driving engagement with a main shaft positioned in a subjacent engine housing (3) to which main shaft, in addition to the power generator and the heat pump, a dual circulation pump is coupled for conveying heated and cooled liquid, from a heating container and a cooling container, respectively, positioned in the engine housing (3) to separate heat and cold storing stations (16, 18). Via a steam separator (21) and a pumping device (22), a steam generator (17) may be connected to the heat storing station (16), which via a steam turbine (19) drives an additional power generator (20) for power production during periods of slack winds.

A wind-powered energy production and storing system, comprising a wind rotor (1) of a compact structure in driving engagement with a power generator (39) via transmission means (28), to which is also connected a heat pump (42) for operation of at least one heat exchanger unit, wherein the wind rotor (1) is a wind wheel having a rim (25) in direct driving engagement with a main shaft (27) positioned in a subjacent engine housing to which main shaft, in addition to the power generator (39) and said heat pump (42), a dual circulation pump (49, 49') is coupled for conveying heated and cooled liquid from a heating container (43) and a cooling container (44), respectively, positioned in the engine housing (3) to separate heat and cold storing stations (16, 18).
Claim 3
Dependent Claim
60 words
A wind-powered energy production and storing system as claimed in claim 1, characterized in that a steam separator (21) energywise connected to the separate heat storing station (16) and a pumping device (22) are connected to a steam generator (17) which via a steam turbine (19) drives an additional power generator (20) for power production during periods of slack winds.
Claim 4
Dependent Claim
56 words
A wind-powered energy production and storing system as claimed in claim 2, characterized in that a blower (65) positioned in the engine housing (3) can optionally be connected to the main shaft (27), said blower having temperature controlled air discharge to the heat storing station (16) and/or the cold storing station (18) and/or said steam generator.
Claim 5
Dependent Claim
68 words
A wind-powered energy production and storing system as claimed in claim 3, characterized in that an oil pump (60) is connected to the main shaft (27) which via a hydraulic activator (59) can activate a gale protection device which is spring-loaded in the normal operational condition of the wind wheel and which turns the wind wheel (1) out of the wind when a certain wind velocity is exceeded.
Claim 6
Dependent Claim
