Solar photovoltaic generation and heat collection circulation integrated system

Abstract

The invention discloses a solar photovoltaic generation and heat collection circulation integrated system. The solar photovoltaic generation and heat collection circulation integrated system comprises a solar photovoltaic / heat collection board, a solar photovoltaic generation and control grid connection system and a solar heat pump heat collection circulation system. The solar photovoltaic generation and heat collection circulation integrated system is characterized in that a photovoltaic cell is arranged on the obverse side of the solar photovoltaic / heat collection board, and an evaporation coil pipe is arranged in an interlayer of the heat collection board. The solar photovoltaic generation and control grid connection system is composed of a storage battery, an electricity charging and discharging controller, an inverter, a grid connection controller and the like. The solar heat pump heat collection circulation system is composed of a compressor, a condenser, a liquid storage device, a thermostatic expansion valve, a water pump, a water tank and the like. While the solar photovoltaic assembly obtains higher photovoltaic conversion efficiency, solar photovoltaic generated electricity and stored electricity provide electricity for the heat pump heat collection circulation system, indoor electricity consumption, lighting and the like, the heat pump device effectively utilizes solar radiant energy to supply heat and hot water to buildings and the like. Efficient utilization of solar photoelectricity and photo-thermal multi-gradient self-circulation is really realized.

Description

technical field [0001] The invention relates to a solar photovoltaic power generation and heat pump technology, in particular to an integrated system of solar photovoltaic power generation and heat collection cycle. Background technique [0002] Under the dual constraints of energy crisis and environmental protection, the issue of building energy conservation has been paid attention by governments all over the world. Solar energy is a safe and environmentally friendly renewable energy source. The all-round comprehensive application of photoelectricity and photothermal energy to build ecological buildings is one of the important ways to achieve sustainable development. Heat pumps have high efficiency and unique advantages in obtaining low-grade heat such as domestic hot water, building heating, and low-temperature drying, and are being more and more widely used in industrial and civil fields. Incorporate solar photovoltaics. The combination of photothermal utilization and h...
