Series-type displacing constant-temperature anti-freezing solar water heater system

Abstract

The invention relates to a series-type displacing constant-temperature anti-freezing solar water heater system. A heat collector and an unconfined storage type heat preservation water tank are connected in series, the system structure is simple, the opposite installing positions of the heat collector and the unconfined storage type heat preservation water tank can be high or low, and the installation is flexible and convenient. The whole system does not adopt any other media and can realize anti-freezing with zero power consumption through the match of a mechanical valve and the energy of tapwater, and the system adopts a new displacing heat-exchange method to realize high-speed high-efficiency heat exchange. The water temperature in the water tank can be controlled and preset, and the use ratio of hot water reaches 100 percent. Compared with the traditional solar water heater, the series-type displacing constant-temperature anti-freezing solar water heater system has the advantages of low cost and higher cost performance.

Description

technical field [0001] The invention relates to a split solar water heater which realizes zero power consumption antifreeze and high-speed heat exchange without using any other non-aqueous medium. Background technique [0002] With the continuous improvement of people's awareness of environmental protection and low carbon, more and more families use solar water heaters. Since the collector part of the solar water heater needs to be installed outdoors, there is a very prominent problem that needs to be solved when the temperature is low and 0 degrees in winter, that is, the exposed parts of the upper and lower water pipes of the solar water heater, and even the entire collector It is necessary to take antifreeze measures, otherwise the upper and lower water pipes are frozen and the solar water heater cannot be used. In severe cases, the water pipes are frozen and cracked, and the heat collector is damaged. The antifreeze technology commonly used for split solar water heaters...

AI Technical Summary

Problems solved by technology

[0003] Let’s first look at the disadvantages of using antifreeze for antifreeze: the first antifreeze is a poisonous, corrosive and volatile liquid, and the hot water in the water tank is used for bathing, washing hands, and even washing vegetables, which may directly enter the body. This kind of potential safety hazard always exists, so antifreeze antifreeze is by no means a safe and reliable method; secondly, antifreeze medium is used as the heat exchange medium, and the heat exchange efficiency is reduced due to the indirect heat exchange of natural circulation; the third antifreeze is in After a period of use, it needs to replenish or change the liquid, which will increase the maintenance cost in the later period; the fourth antifreeze reduces the temperature of the antifreeze while preventing freezing, which will cause more extra sunlight to replenish during the day

[0004] Next, look at the heat preservation and antifreeze method or the heating and antifreeze method. One of these two methods has the problem of electricity safety, and the other requires the consumption of additional electric energy. It is not a method worthy of vigorous promotion.
