Description

Utilize the generating and the refrigerating system of solar energy-semiconductor thermoelectric effect

The present invention is a kind of solar energy and generating that cooperates with thermoelectric refrigerating semiconductor/heating device and refrigerating system of utilizing, it is characterized in that the solar energy assembled is absorbed to emit from release end of heat by the heat absorbing end of thermoelectric refrigerating semiconductor/heating device adds utilization again, and advantage is to utilize the part of solar energy heating to reach higher temperature and increase the benefit.

In the electricity generation system of utilizing the solar energy-semiconductor thermoelectric effect, the solar energy assembled is absorbed by the heat absorbing end of additional thermoelectric refrigerating semiconductor/heating device and emit from release end of heat, make to produce thermal current or steam in thermal current generator in the TRT or the steam generator, promote turbo blade and rotate and make generator for electricity generation.In refrigerating system, then the solar energy of Ju Jiing is absorbed by the heat absorbing end of thermoelectric refrigerating semiconductor/heating device and emits from release end of heat, bromizates in the generator of lithium absorption cold, hot water machine lithium bromide-aqueous temperature and raises and be transformed into steam and moisture less lithium bromide-aqueous solution.With steam is that medium returns in the cyclic process of generator by condensation, throttling, evaporation, absorption, has produced cold water (about 4 degree).The flow through release end of heat of another thermoelectric refrigerating semiconductor/heating device of the cold water that lithium bromide absorption cold, hot water machine produce reaches the effect of refrigeration so that its heat absorbing end absorbs a large amount of heats.

A kind of solar energy and generating that cooperates with thermoelectric refrigerating semiconductor/heating device and refrigerating system most preferred embodiment of utilizing below is described:

Make the reflector A of the gathering solar energy that the similar radar antenna of a shape makes with sheet metal, with a large amount of solar energy collectings to the circular spherical shell B of its central part.Many layers are arranged in the spherical shell, and outermost layer B1 is the heat absorbing sheet of thermoelectric refrigerating semiconductor/heating device heat absorbing end, and the inside one deck B2 is the fin of thermoelectric refrigerating semiconductor/heating device release end of heat, and the inside one deck B3 also is the fin of release end of heat again.Adorning several thermoelectric refrigerating semiconductor/heating devices between B1 and the B2 and between B1 and the B3, power when sunshine is sufficient by solar photocell or batteries, because the effect of solar energy of assembling and process semiconductor device, can make the temperature of B2 reach more than 100 degree Celsius than the high tens of degree of B1, comparable B2 is higher for the temperature of B3.So just can make the air between B2 and the B3 become thermal current, be equipped with above causing by the pipe stream on the spherical shell B among the spherical shell G of turbo blade and go, blade rotation is driven between the rotor rotary electrification B3 of generator E and the B4 can fill the bigger material of thermal capacity, make the temperature of B3 and the B4 back that raises keep more stable.After thermal current rises.Cold air providing by import between B2 and the B3 below B can be equipped with among the spherical shell C of steam engine turbo blade by the feeding of the pipe above the B by following feeding steam in B4 inside, drives steam engine and rotates and make generator D generating.Another kind of scheme is the generator of the inside of B4 as lithium bromide absorption cold, hot water machine.Also having a kind of embodiment is that the generator of refrigerating system separates with electricity generation system, two cover solar collectors are promptly arranged, be the generator of lithium bromide absorption cold, hot water machine between spherical shell B2 of one of them and the B3, B4 inside can be used as the not enough or overcast and rainy high steam that the feeding donkey boiler provides below B of sunlight.(in the refrigerating system that this and electricity generation system are separated, there are not turbo blade and generator on the spherical shell B certainly.Promptly there are not C, D, E, G)
