Solar energy saving system using gas and electricity as compensation

Abstract

A solar energy saving system composed of solar collectors, a custom built heat pump and a conventional gas heater, a centralized computer control system, a group of sensors, pumps and valves, and the mechanical and electrical connections, is disclosed herein along with the processes and methods for applying the system.

1 . A solar energy saving system with conventional gas and electricity as compensatory, comprising
 a heat pump composed of condenser, compressor, vaporizer, expansion valve, refrigerant storage, phase change filter, wherein the condenser forms part of the solar collectors and water heating exchanger, or the refrigerant-water vaporizing/condenser, or refrigerant-air vaporizing/condenser, the condenser forming the heat pump “energy source” gets the energy from the air, solar, electricity and gas;   a conventional gas water heater is intelligently connected with the system via pipes and controlling signal;   a computer control unit loaded with controlling softwares controls thermal circulation of the solar collectors, with or without heat pump and gas heater working in conditions of using the most of solar energy and the least of conventional energy;   a group of sensors, pipes, valves and pumps applied in the system.   
   
   
       2 . The solar energy saving system of  claim 1 , wherein the heat pump includes air-to-water, or air-to-air, or water-to-water, or water-to-air differing types, in which the condenser and evaporator are fabricated differently and performed functions of heating and cooling. 
   
   
       3 . The solar energy saving system of  claim 1 , wherein the conventional gas water heater is intelligently integrated with connection to the heat pump water-vaporizing/condenser or direct connection to the air-handler water conduit providing supplementary heating function when solar energy is absent and ambient environment temperature is really low. 
   
   
       4 . The solar energy saving system of  claim 1 , wherein a heat exchanger as part of the water-vaporizing/condenser exists providing heat recovery function when the heat pump is working for cooling. 
   
   
       5 . A solar energy saving system, comprising
 the solar collector, thermal circulating medium and energy storage container, wherein the collector could be solar vacuum tube, solar vacuum heat superconductivity tube or solar metal flat panel; the thermal circulating medium is water or other anti-freeze liquid.   
   
   
       6 . A computer software system performs the intelligent control function in the system, where it accepts inputs from sensors and outputs controlling signals to valves and pumps in the system in the logic of using the solar energy in all possible situation, while provide conventional electricity or gas energy only in the necessary conditions.
