Embodiment Construction

[0026] figure 1 It is a schematic diagram of the connection structure of the main switching valve (105), auxiliary switching valve (106), upper water mixing valve (107) and lower water pressurization valve (108) embedded in the thermal insulation layer (302) of the hot water storage tank (101) . The temperature control device (103) adopts a whole machine, which contains waterway switch, temperature sensor and pressure sensor; the ventilation interface and auxiliary interface of the hot water storage tank (101) are not shown in the diagram, but It does not mean that it does not exist. In fact, there are generally multiple auxiliary interfaces for the hot water storage tank (101), such as electrical auxiliary heating interfaces, water level gauges, water temperature gauges, and safety valve interfaces. This is common knowledge in the industry.

[0027] According to the connection shown in the figure and the different working conditions of the system, the system has two sets of...

Abstract

A brand new dual-pressure split type solar water heater system comprises a heat storage water tank, a thermal collector, a temperature control device, four mechanical valves comprising a water supply mixed valve, a water discharge pressurizing valve, a main switching valve and an auxiliary switching valve, and connecting pipelines among various parts, wherein the heat storage water tank and the thermal collector are independent mutually and perform heat exchange by means of circular displacement, so the heating speed and the heat exchange efficiency are high. The system achieves multiple working states with zero power through panel knobs of the switching valves, and can automatically supply water, heat water at the fixed temperature, exchange heat, store heat, supply hot water in an unpressurized mode, supply hot water in a pressurized mode, suck, empty and prevent frostbite. The whole system has a simple structure and is low in cost. The distance between the heat storage water tank and the thermal collector can be lengthened, so that the thermal collector is in the south, the heat storage water tank is in the north and a building is more integrated. The system is suitable for the urban solar water heater market and has high market popularization value.

Description

technical field [0001] The invention relates to a brand-new split solar water heater capable of simultaneously supplying non-pressurized hot water and pressurized hot water. Background technique [0002] Urban solar water heaters will be used more and more widely, and building integration is the development direction of urban solar water heaters. Currently, solar water heaters designed for urban residents' balconies are generally split balcony wall-mounted solar water heaters. The structure and configuration it adopts is bearing Pressurized heat collector and pressurized hot water storage tank with heat exchange device. Most of the heat collection and heat exchange medium in the heat collector is antifreeze. The heat exchange method between the heat collector and the hot water storage tank is Natural circulation heat exchange, the hot water supply is completely through the cold tap water entering the hot water storage tank to push the hot water out, and the whole system is i...
