Description

A kind of loop heating system of water tank free solar water heater

Technical field

Technical field of solar water heaters is the utility model is related to, specifically a kind of water tank free solar water heater Loop heating system.

Background technology

Water tank free solar water heater utilizes power PC M phase-change materials, and will by concentric locking collar tubular type parallel-connection structure Energy-accumulation material is inserted in solar energy heat collection pipe, the storage in place after solar energy heat collection pipe thermal-arrest is realized, with " PCM phase-changing energy-storings Material " substitutes the solar water heating system using " water " as heat storage medium, realizes cistern free, the module of solar water heater Change.Water tank free solar water appliance has the advantages that the thermal efficiency is high, thermal starting is fast, therefore is widely used.

Current water tank free solar water heater typically installs heating rod in the thermal-collecting tube of heat collector, in heat collector Bathing is heated by heating rod when water temperature does not reach bathing temperature, but this mode has following defect：1. due to heating rod In thermal-collecting tube, and thermal-collecting tube is installed on outdoor, it has not been convenient to dismantle, therefore inconvenience maintenance after heating rod damage；2. plus Hot pin damage easily causes leaky, potential safety hazard be present；3. heating needs the water in heat collector integrally lifting temperature, and It is uneven to heat water temperature, sub-fraction hot water is used only in each bathing, and the water being heated in heat collector can be remaining most of, causes Heat waste, increase electric energy loss.

In order to solve the above technical problems, installation is hot device on the hot-water line of system, i.e., hot device is that one kind can pass through electricity Son heating component is quick to heat flowing water, and can control water temperature, flow velocity, power etc. by circuit, water temperature is reached suitable The water heater of the temperature of human body bathing.When temperature in solar energy heat collection pipe does not reach bathing temperature also, unlatching be hot device i.e. Can bathing, i.e., hot device can start heating generally within the several seconds, and to reach the purpose of instant-heating, i.e., the power of hot device is general very Height, in 6kw-8kw, still, if the design of user's total capacitance is insufficient, i.e., hot device can not just use.

Utility model content

The utility model proposes a kind of loop heating system of water tank free solar water heater, circulating pump is added, is coordinated I.e. hot device uses, when the water temperature in heat collector is very low, from the relatively low i.e. hot device of power, you can realize the quick of relatively low water temperature Heating, greatly reduces power consumption.

What the technical solution of the utility model was realized in：A kind of circulating-heating system of water tank free solar water heater System, including heat collector, controller, cold water pipe, hot-water line and spray head；One end installation water intaking valve of the cold water pipe, the other end It is connected with the cold water inlet of controller, the cooling water outlet of controller is connected with heat collector water inlet end, described hot-water line one end and spray Head connection, the hot water outlet connection of the other end and controller are drenched, the hot water inlet of controller is connected with heat collector water side；It is described Hot-water line installs water mixing valve on the position of spray head；The water mixing valve is also connected by mixed water pipe with cold water pipe；Water mixing valve Installation is hot device on hot-water line between controller；That is the power of the hot device is 1kw-3kw；Between water intaking valve and controller Cold water pipe on circulating pump is installed.

By adopting the above-described technical solution, the utility model has beneficial effect following prominent：

1st, the temperature in solar energy heat collection pipe is general long-term all more than 30 degree, adds circulating pump, and it is heat to coordinate small-power Device uses, if water temperature does not reach bathing temperature also, unlatchings be hot device can bathing, but at continuous more days cloudy days winter in spring Or the rainy day, when the water temperature in heat collector is very low, while opening is hot device and circulating pump, and the water circulation in system is heated, made Reach more than 30 °, then individually opening be hot device can bathing, accelerate the programming rate of system, and make water temperature evenly, Bathing is more comfortable.

2nd, from the relatively low i.e. hot device of power, it can both meet that user was not enough to bear high-power i.e. hot device in total power load In the case of realize being rapidly heated for relatively low water temperature, realize bathing, greatly reduce power consumption again.

3rd, the shortcomings that heating rod is installed on existing potential safety hazard and inconvenient maintenance in outdoor thermal-collecting tube is overcome.
