Abstract
Designs of cooling systems that operate entirely on solar energy are disclosed. Such cooling systems may be used in refrigeration and air conditioning. According to one aspect of the designs, a solar energy collecting device is disposed outdoor to collect solar energy. A first heat-to-electricity pump operating on heated liquid is provided to produce electricity. A storage tank is used to store heated water. A second heat-to-electricity pump is disposed in the storage and operates on the heated water to generate electricity. A cooling system operates on at least three types of working fluids to achieve low temperature evaporation and high temperature condensation to derive cooling effects. A working unit powered by at least one of the first generator and the second generator is provided to utilize the cooling effects from the cooling system.
