Abstract

Abstract This invention relates to a method and an apparatus which can be used either to heat or cool water through solar technology merely by the addition or removal of a few materials from a basic structure, thus making it possible to expose water to sunlight in winter so as to provide hot water for heating buildings, or to chill water by exposing it to cold night air during summer so as to cool the same buildings. The basic object is to reduce the cost of hot and cold water thus produced by using what is essentially a water chiller as a basic structure, and then adding it to during winter a glass panel at the top and an insulating panel at the bottom so the device can be converted into a solar water heater. Also provided are ways for heating or cooling several small houses or one very large building through the use of automatic controls, large storage tanks, and an enclosed collector area located in the backyard and in the midst of several houses so that it is not necessary to mount the devices on the roof of the buildings themselves, as has been the practice in most solar energy projects.
