Binary compatible solar water heater system with brand new framework

Abstract

The invention discloses a binary compatible solar water heater system with a brand new framework. The entire system comprises a heat collector, a heat storage water tank, a temperature control valve, a water level control valve, an automatic switching valve and a manual switching valve; when anti-freezing and exhausting functions are realized, the entire system further comprises a respiration valve or a self-restoration one-way valve and a pipeline for connecting all components, so that upper and lower water paths can be switched automatically; serial connection and replacement heat exchange methods are adopted for the heat collector and the heat storage water tank, so that the heat storage water tank in an integral solar water heater is easily positioned below the heat collector; in a split non-pressure-bearing solar water heater, the horizontal distance between the heat collector and the heat storage water tank is prolonged; and moreover, the water temperature of the heat storage water tank is definite regardless of an all-in-one machine or a split machine. In the entire system, a fully-mechanical structure and a single pipe are adopted for feeding and discharging water, so that automatic control over water feeding, automatic control over water discharging, automatic control over emptying and zero power consumption are realized. The binary compatible solar water heater system has the advantages of very simple overall framework, low cost, high performance cost ratio and good social benefit and economic benefit.

Description

technical field [0001] The invention relates to an integrated or split non-pressurized solar water heater system which can be constructed simultaneously by adopting a new structure, and belongs to the field of solar heat utilization. Background technique [0002] With the continuous improvement of the people's awareness of environmental protection, the application of solar water heaters is becoming more and more extensive. At present, the solar water heater product with the highest penetration rate in China is the roof integrated machine. Whether the integrated machine uses vacuum tube collectors or flat plate collectors, Due to the working method of natural circulation heat exchange, the water tank must be placed above the heat collector, and the distance between the heat collector and the water tank is very limited, that is to say, the relative position of the two is fixed and there is almost no adjustment Space. The highest point of each solar water heater is a bulky wat...

AI Technical Summary

Problems solved by technology

This is a top-heavy structure. It is this kind of structure that puts forward very high requirements on the material of the supporting frame and the location of the installation. In addition, the ability of the solar water heater with this structure to resist typhoons is greatly reduced.

[0003] Is there a better structure to solve the above problems, so that the new solar water heater system, with the same structure, can be installed on the roof like an all-in-one machine, or can be installed on the roof like a split machine
