一、前言 自美国R·Winston教授发明了理想的圆柱形聚光器以来,已引起世界各国太阳能研究人员的极大兴趣。这种复合抛物面聚光器(简称CPC)的最大优点是具有较大的接收角,因而无需昼夜跟踪;接受太阳散射的能力比成像聚焦集热器强;镜面制造与安装精度不必十分严格;集热温度为100℃～300℃等等。因此CPC装置对于驱动空调,工艺用热,全能系统,冬季气温低的地区取暖,洪应开水或热水等具有特殊的作用。各国的太阳能研究人员都试图
I. Introduction Since Professor R Winston of the United States invented the ideal cylindrical condenser, it has attracted great interest of solar researchers from all over the world. The biggest advantage of this compound parabolic concentrator (referred to as CPC) is that it has a larger acceptance angle and therefore does not require day and night tracking; the ability to receive solar scattering is stronger than imaging focused collectors; the precision of mirror manufacturing and mounting does not have to be very strict; Hot temperature of 100 ℃ ~ 300 ℃ and so on. Therefore, the CPC device has special functions for driving air conditioners, process heats, omnipotence systems, heating in areas with low temperature in winter, flood watering, or hot water. Solar energy researchers from all over the world have tried
