Photovoltaic Powered Solar Jet and Direct Evaporation Composite Refrigeration Device

Abstract

The invention provides a photovoltaic power supply type solar injection and direct evaporation composite refrigerating device. The photovoltaic power supply type solar injection and direct evaporation composite refrigerating device is formed by integrating a solar photovoltaic power supply system, a solar injection refrigerating system and a direct evaporation cooling system in a communicating mode. According to the photovoltaic power supply type solar injection and direct evaporation composite refrigerating device, electric energy and heat energy are provided for buildings with solar energy being a power source, refrigerating is conducted on the buildings by combining the direct evaporation cooling system, the supply and demand relation between the refrigerating capacity and an air conditioner load is adjust and balanced, and the effect that power consumption is minimum under the condition of the same refrigerating capacity is achieved.

Description

technical field [0001] The invention relates to a solar injection and direct evaporation composite refrigeration device, in particular to a solar energy injection and evaporation composite refrigeration device driven by photovoltaic power supply with solar energy. Background technique [0002] In my country's remote mountainous areas, deserts, frontiers, and islands, the lack of power resources has brought great inconvenience to life, work, scientific investigation, and resource development. Especially in Xinjiang, the highest temperature in summer is as high as 40°C. There is an urgent need to develop a high-efficiency and energy-saving refrigeration equipment that does not depend on external power supply. [0003] Through searching the prior art, it is found that in order to realize the purpose of saving electric energy, the refrigeration system is usually driven by solar energy or jointly driven by solar energy and other energy sources. For example, the existing invention...

Problems solved by technology

[0004] However, the above-mentioned energy storage type, solar gas jet refrigeration system, solar jet refrigeration device and solar jet and compression integrated refrigeration device, although the main driving energy is solar energy, all need electric energy to drive power-consuming devices such as working medium pumps, especially with When gas-powered, not only does a gas supply need to be available, but energy savings from solar-driven cooling are offset by inefficient gas-assisted driven cooling systems

[0005] Although photovoltaic technology is relatively mature, the photoelectric conversion rate is still low. Considering factors such as the number and area of ​​photovoltaic panels, photovoltaic power supply is difficult to meet the electricity demand of traditional air conditioners
