Embodiment Construction

[0019] Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings. In the various figures, identical elements are indicated with similar reference numerals. For the sake of clarity, various parts in the drawings have not been drawn to scale.

[0020] see figure 2 , the combined solar power supply system of the present invention includes a photovoltaic power-heating device 100 , a heat raising device 200 and a building energy supply device 300 . The photovoltaic power-heating device 100 generates electric energy and heat. The heat is transferred to the heat raising device 200 by using the heat conduction medium to further increase the temperature of the heat conduction medium (that is, to increase its energy grade). Then, the heat is transferred to the building energy supply device 300 by using the heat conducting medium to generate cooling / heating output.

Abstract

The invention discloses a solar energy combined energy supply system and a solar energy combined energy supply method. The solar energy combined energy supply system comprises a photovoltaic electric heat combined device for thermal coupling by utilizing a heat-conducting medium, a heat lifting device and a building energy supply device, wherein the photovoltaic electric heat combined device generates heat and transfers the heat to the heat lifting device; and the heat lifting device improves the temperature of the heat-conducting medium and transfers the heat to the building energy supply device; and the building energy supply device generates at least one of cold output and heat output. The solar energy combined energy supply system can provide multiple energy output, and improves the generating efficiency and heat utilization efficiency of solar panels.

Description

technical field [0001] The present invention relates to a combined solar energy supply system and method thereof, more particularly to a combined solar energy supply system and method for providing multiple energy outputs. Background technique [0002] The traditional building summer cooling system is based on central air conditioning or small single air conditioning system as output equipment, including compression refrigeration units powered by electricity. In recent years, with the improvement of people's awareness of energy and the deepening of their understanding of the concept of energy saving and emission reduction, a series of more energy-saving and consumption-reducing refrigeration and cooling methods have been adopted, such as heat pump refrigeration systems, (waste heat or waste heat) Absorption / adsorption refrigeration systems, etc. [0003] However, the main problem of these refrigeration systems is the high requirement for energy grade. For example, compressi...
