Solar energy-conserving system and method compensated by utilizing gas and electric energy

Abstract

The invention belongs to the energy saving field of solar energy, particularly to a composite solar energy heat pump energy-saving system used with common gas water-heater and the method thereof. The solar energy energy-saving system utilizing compensation of gas and electric energy comprises a heat pump device and a water tank connected with a solar energy collecting device, further comprises a common gas water heater connected with the solar energy collecting device and a central controller connected with the solar energy collecting device, heat pump device and the common gas water heater. The system only takes the steps of using solar energy, the heat pump device to compensate, and the gas water heater in order to make use of energy. By using the proposal, the present situation of using fuel gas or electric power as energy for heating water, heating and air conditioning is solved. Using solar energy as the major energy supply and adding a small quantity of electric power and fuel gas can satisfy water indoor water supply, heating and air conditioning systems of building. So the consumption of tradition energy is effectively reduced.

Description

technical field [0001] The invention relates to the field of solar energy energy saving, in particular to a solar energy and heat pump composite energy saving system and method used in combination with an existing common gas water heater. Background technique [0002] Solar energy is inexhaustible and inexhaustible green energy. Using solar energy as much as possible with the hot water, heating, and air-conditioning systems of ordinary households, businesses, and enterprises can greatly reduce the use of traditional energy sources, so as to achieve the goals of energy conservation, emission reduction, and reduction of the global greenhouse effect. However, the use of solar energy has a strong seasonality and cannot meet all the needs of people at present. For example, solar water heaters, the hot water produced in the season of insufficient sunlight cannot reach the shower temperature that people need. In view of the above reasons, people have adopted multiple methods to m...
