needs heating and melting by natural gas or electricity, to lock and unlock heat must rely upon the operation of the
salt pump and the heat exchanger with two molten salt insulation tanks reciprocating for indepandent storing
molten salt at different temperatures, which not only causes its mechanism and operation management very
complicated and expensive, but the molten salt pump being a limited life and frequent breakdown, and once the
temperature is out of control,the molten salt will be condensed and solidified, paralyzing and crashing the whole
system with extremely high cost for remelting the molten salt.

that wherein: the power output shaft of the vertical windmill is connected to the power input shafts of the low
pressure compressor, of the medium-pressure compressor and of the high-pressure compressor, the air is
compressed by three of which in sequence, and being delivered to the compressed air bag; the compressed air in
the compressed air bag, after passing through the compressed air pipeline, through the pool with molten salt for
exchanging heat and the hot water pool and being preheated, is blowen into the first-stage expander, outputting
mechanical power and generating electricity by discharging cold air, which, via the pipeline, is exchanges heat
with the ice-water mixture pool, whereby, the pool absorbs and reserves cold energy. The cold air in the pipeline
is preheated by the ice-water mixture, and exchanges with the heat of heat-conducting oil out of the heat
exchanging pool with molten salt, and obtaining the higher temperature compressed air, which is input to the
second-stage expander for outputting mechanical power and generating electricity, and the multi-stage expander
are going same subsequent orders as such.
8. The method for A muilt-compressor and muilt-function electricity generating system directly linking to wind
mill according to claim 7, wherein the thermal energy of the low-pressure compressor, the medium-pressure
compressor and the high-pressure compressor, via the coils, is input to the heat-exchanging pool with molten salt
and the hot water pool, wherein the molten salt of heat-exchanging pool embed said coils, inside of which, the air
is compressed and heated to a high temperature of 150°-200° from the upper layer spiring down to the lower layer,
and gradually heating the molten salt, until the whole molten salt in the heat-exchanging pool is melted, and the hot
air that has not been completely cooled down by the molten salt enters the coils of the hot water pool for continous
exchanging heat.
9. The method of A muilt-compressor and muilt-function electricity generating system directly linking to wind
mill according to claim 7, wherein the heat-exchanging pool with molten salt is connected to the heat-conducting
oil modules, and the heat-conducting oil exchanges heat in the molten salt heat of the heat-exchanging pool through a pipeline.
10. The method for a A muilt-compressor and muilt-function electricity generating system directly linking to wind
mill according to claim 7, wherein the compressed air bag arranged in the cave or deep sea, and the compressed
air bag in the cave is submerged in the water for stable hydrogenic prussure, said compressed air bag via pipelines
connecting rivers, lakes and ponds, which, after passing through the axial hydro-generator, are supplemented with
water by the pipelines to the caves.
