Problems solved by technology

One is that the frontal heat loss of flat-panel photovoltaic panels is high, resulting in a decrease in thermal efficiency, and the other is that reinforcement measures are used to resist wind loads, resulting in increased roof loads
[0004] In addition, in the non-heating season, the building only needs domestic hot water, the heat load decreases, and the requirements for water temperature are also reduced. At this time, if the heat is still provided through the heat pump cycle to meet the domestic hot water load demand, it is like a "big horse and a small cart" , consumes a lot of power

Embodiment Construction

[0022] Concrete technical scheme of the present invention is:

[0023] Such as figure 2 As shown, a heat pipe-type photovoltaic power generation heat collection assembly mainly includes a double-glass vacuum tube 4 , an aluminum plate 16 , a photovoltaic plate 7 , a U-shaped copper tube 6 and a heat pipe 5 . Roll up the two ends of the longitudinal length of the aluminum plate 16 downwards, respectively tightly clamping one side of the U-shaped copper tube 6, and the middle of the aluminum plate 16 is an upward concave arc to clamp the heat pipe 5, in the positive direction of the evaporation end of the heat pipe 5 The outer surface (i.e. the sunny side) is coated with a heat-absorbing coating 17, and two narrow strip photovoltaic panels 7 are pasted on the aluminum plate 16 and are respectively located on both sides of the heat pipe 5, and the aluminum plate 16 is connected with the U-shaped copper pipe 6 and the heat pipe 5. Paste it with heat-conducting glue; place the st...

Abstract

The invention relates to a combined heat and power combined energy supply system, which mainly includes a heat pipe type photovoltaic power generation heat collector, a compressor, a water-cooled condenser, an air-cooled evaporator, an expansion valve, a water pump and a heat storage tank. Through the ingenious design of the heat pipe photovoltaic power generation module structure and system, the heat pipe heat collection, photovoltaic power generation, photovoltaic heat pump cycle and air source heat pump cycle are organically combined. The present invention also provides the working method of the above combined heat and power cogeneration composite energy supply system, and can adopt different operation modes according to actual needs: "photovoltaic power generation + heat pipe heat collection" mode, "photovoltaic power generation + photovoltaic heat pump cycle + heat pipe heat collection" mode, "air source heat pump cycle" mode. When the heat collection of heat pipes and the photovoltaic heat pump cycle cannot meet the demand, the air source heat pump cycle is used as an auxiliary measure to ensure the safe and stable operation of the system.

Description

technical field [0001] The present invention relates to the technical field of solar energy utilization, in particular to a new type of heat pipe photovoltaic power generation heat collection assembly in solar heat and power cogeneration and a heat pipe photovoltaic power generation heat collector using the heat pipe photovoltaic power generation heat collection assembly and A combined heat and power combined energy supply system. Background technique [0002] At present, solar energy utilization technologies mainly include solar photovoltaic power generation and solar water heaters. Solar water heaters are mainly used for domestic domestic hot water, but when used for building hot water heating, there are problems such as low outlet water temperature, low thermal efficiency, and poor stability. Solar photovoltaic panels are the main device for solar power generation. They can not only generate electricity to supply electricity to buildings, but also can be used as exterior...
