Problems solved by technology

At present, the proportion of high-rise buildings in urban construction and development is increasing day by day. The remaining water pipe between the water outlet of the hot water storage tank on the roof and the user is tens or even hundreds of meters long. Let go of a large amount of cold water in the remaining water pipes, resulting in a large waste of water resources, bringing a lot of trouble and inconvenience to users, and also bringing certain economic losses to users
In addition, especially in the cold northern regions, outdoor pipelines of solar water heaters are often frozen in winter

Embodiment 1

[0019] see figure 2 , the heat preservation residual water pipe 6 is a steel pipe 13 wrapped with a polyurethane rigid foam insulation layer 11 and a high-density polyethylene outer sleeve 10 on the surface, and the polyurethane rigid foam insulation layer 11 is provided with a detection line 12 for detecting the leakage position of the pipeline. Before installing the thermal insulation surplus water pipe 6, first use steel pipe and polyurethane rigid foam insulation and high-density polyethylene material to prefabricate the thermal insulation residual water pipe, and then install it.

[0020] see image 3 , the flange type electric heater 8 is composed of a flange plate and three electric heating tube groups 14 with a rated voltage of 24V welded on its upper end surface and a junction box installed on its lower end surface. The flange type electric heater 8 passes through the flange The flange on the side of the plate and the remaining water pipe 6 is fixedly connected with...

Embodiment 2

[0026] Embodiment 3: see figure 1 , 2 , 3. The composition and connection relationship of this solar water heater residual water pipe heating system based on solar energy and wind energy are the same as those in Embodiment 1. The system is used in a 15-storey building, with 30 solar hot water users per unit, and the inner diameter of the remaining water pipe is 30mm. 30 flanged electric heaters 8 and 30 gate valves 7 are arranged on the remaining water pipe 6 of each unit, and 30 three-way and household ball valves 9 are used respectively. Five electric heating tube groups 14 with a rated voltage of 4V are welded on the upper end of the flange of the flange electric heater 8, the voltage of the lead-acid battery group 17 is 4V, and the wind power generator 20 adopts a small DC wind power generator with a power of 8KW. machine.

Abstract

The invention relates to a solar energy and wind energy-based solar water heater surplus water pipe heat compensation system, and belongs to the technical field of solar heat supply. The system comprises a wind energy and solar energy hybrid power supply system, a heat insulating surplus water pipe, a hot water gate valve arranged at the upper end of the heat insulating surplus water pipe, a household ball valve arranged between the surplus water pipe and each household hot water pipe through a tee joint, a household gate valve arranged on the heat insulating surplus water pipe and a household flange electric heater; the upper end of the heat insulating surplus water pipe is connected with a water outlet of a heat storage water tank on the top of a building through a head gate valve; each household flange electric heater is arranged on the heat insulating surplus water pipe below each household tee joint; the gate valve is arranged on the heat insulating surplus water pipe between each household tee joint and the flange electric heater; and the output end of the wind energy and the solar energy hybrid power supply system is connected with each household flange electric heater. Power is generated through wind force and solar energy and supplied to the flange electric heater to heat cold water in the surplus water pipe. The solar energy and wind energy-based solar water heater surplus water pipe heat compensation system has the advantages of water saving, energy saving, capacities of increasing hot water supply amount and improving climatic adaptation of a solar heating system, and the like.

Description

technical field [0001] The invention relates to a heating system for a residual water pipe of a solar water heater, in particular to a heating system for a residual water pipe of a solar water heater based on solar energy and wind energy, and belongs to the technical field of solar heating. Background technique [0002] At present, most of the solar water heater residual water pipes on the market just carry out various thermal insulation measures on the residual water pipes to reduce the heat loss of the residual water pipes. But still very little is carried out heating to remaining water pipe, is almost blank. At present, the proportion of high-rise buildings in urban construction and development is increasing day by day. The remaining water pipe between the water outlet of the hot water storage tank on the roof and the user is tens or even hundreds of meters long. Letting go of a large amount of cold water in the remaining water pipe causes a large amount of waste of wate...
