The near-zero emission energy supply system with complementary photovoltaics and air-source heat pumps is a comprehensive energy utilization system that integrates photovoltaic power generation, photovoltaic waste heat, and air-source heat pump technologies. This system is mainly composed of photovoltaic power generation/energy storage, air-source heat pumps, circulation pumps, hot water storage tanks, waste heat utilization systems, and control systems, among others. Photovoltaic modules provide electrical energy for the system, enabling heating and cooling supply. While generating electricity, photovoltaics also produce waste heat. Heat dissipation fins are used to collect the waste heat behind the photovoltaic panels with air as the medium and transmit it to the air-source heat pump. The heat pump utilizes the waste heat from photovoltaics to provide heating and hot water services for users.
Functional charateristics
• Photovoltaic power generation is stored and consumed locally, providing electrical support for electrical equipment such as heat pumps and water pumps, thereby achieving near-zero carbon emissions.
• After heat dissipation fins recover the waste heat from photovoltaics, they can cool the photovoltaic modules and improve their efficiency. Meanwhile, they can increase the temperature on the evaporator side of the air-source heat pump, thereby enhancing the COP of the heat pump system.
The high-efficiency heating system combining solar energy with air-source heat pump is equipped with a control system, which can monitor and adjust the operation of the entire system in real time. This enables solar energy and heat pump technologies to automatically complement each other according to environmental conditions and energy demands, thereby improving energy utilization efficiency and system stability, and ensuring that the hot water and heating needs of residents are met under different weather conditions.
