Abstract
A solar powered compressor and pump is disclosed having a trough-shaped parabolic reflector for heating a conduit of refrigerant as it passes through the system. The compressor/pump combination includes a lens that covers the reflector and insulates and protects the reflector from the elements while increasing the intensity of the sun's energy entering the reflector. The reflector converts the sun's energy into heat that superheats the refrigerant as it passes through the reflector, reducing or eliminating the amount of mechanical work that the system has to do to achieve the needed superheating stage.
Claims4
A solar powered refrigeration system comprising:
- a first subsystem comprising a compressor, an evaporator, a condenser, and an expansion valve, and a first refrigerant cycling through each element of the first subsystem;
- a second subsystem comprising a solar compressor and a second heat exchanger, and a second refrigerant circulating through the solar compressor and the second heat exchanger, where the second refrigerant is different from the first refrigerant, and wherein the second refrigerant is solar heated by the solar compressor to superheat the second refrigerant, wherein the superheated second refrigerant from the second subsystem transfers energy to the first subsystem at the solar compressor to reduce, but not eliminate, a load on the compressor of the first subsystem, the solar compressor having a parabolic reflector controllably oriented so as to optimally direct sunlight to heat a conduit containing the second refrigerant;
- wherein the efficiency of the first system is increased by reducing an electrical power requirement of the compressor of the first subsystem by using superheated refrigerant generated by the second subsystem.
