以色列阿勒尔工业公司研制了一种新型太阳池,称为“热湖”。它可以提供采暖和制冷的能量,还可以提供低压蒸汽和热水。据说,它不仅成本效益最好,而且可在夜间储热达数月之久。它可充以任何种水,而不需添加盐和其他化学物质。 Alrael Industries, Israel, has developed a new type of solar pool called the “hot lake.” It can provide heating and cooling energy, but also can provide low-pressure steam and hot water. It is said that it is not only the most cost-effective but also heat-stored for months at night. It can be filled with any kind of water without adding salt and other chemicals.
