Description

A kind of solar hot water heating system
Technical field
The present invention relates to solar water heating field.More particularly, the present invention relates to the hot-water heating system of a kind of separated type solar hot water and heating.
Background technology
In the face of society increases day by day to the demand of energy-conserving and environment-protective facility, solar water heater more and more is subjected to consumer's welcome.
More common in the market solar water heater is an integral type, the water tank and the heat collector that are solar water heater are fabricated to one, because its water inlet pipe and water outlet pipe only is a same pipe, necessary closing gate valve during bathing, utilize that existing water carries out bathing in the water tank, can not the feed-tank supplementing water in the time of bathing, make troubles to the user.
In addition, the water supply of present solar water heater and heating system have two kinds: a kind of for pressure bearing system, it is very high that this kind system implements cost, and install very complicatedly, safeguards also trouble; The non-pressure bearing system of another kind of employing relies on drop that the water in the water tank is emitted, if supply water with the water pump pressurization, will cause system water supply hydraulic pressure shakiness.
In addition, the water in the water heater in the market all will be changed every day, and auxiliary electrothermal tube fouling is serious, and the life-span shortens greatly; Vacuum tube can not cause decrease in efficiency because of fouling.
Summary of the invention
The present invention be directed to the improvement of prior art, it provides a kind of longer solar hot water heating system of simple life-span of installation, that is, the comfortable heat energy system of THREE-TANK SOLAR SYSTEM is called for short the TTSS hot-water heating system.Separated type solar hot-water heating system provided by the invention can reach the water effect of pressure-bearing solar system and with low cost.
The present invention is achieved by the following technical solutions:
A kind of split type solar hot water heating system, its water supply and add the scheme that the non-pressure-bearing of thermal recovery combines with pressure-bearing is by three courage attemperaters, solar thermal collector, control centre, Digiplex, water circulating pump, magnetic valve, electric T-shaped valve, gas heater, heating radiator/heating coil pipe, check valve, formations such as electric wire and water pipe.
Non-pressure-bearing bottom inner container splendid attire heat-exchange working medium (being generally running water or deionized water) links to each other with the water circulating pump import by outlet pipe in its underpart in the three courage water tanks.Non-in addition pressure-bearing inner bag inside is provided with the electrical heating servicing unit, selects for the auxiliary thermal source kind.Turnover cold water pipe and hot-water outlet pipe are arranged in the pressure-bearing inner bag, be used for domestic hot-water supply to use.
The magnetic valve that switches usefulness is installed on the circulating pump discharge pipe road, and can switch between two function routes by the open and close of two magnetic valves: the one tunnel is used for solar energy heating, and one the tunnel is used for auxiliary heating and heating.
Heating process: solar energy preferentially heats the working medium in the non-pressure-bearing bottom inner container, heats the pressure-bearing inner bag simultaneously.When the working medium in the non-pressure-bearing bottom inner container was heated to 60 ℃, if the heat collector temperature also is higher than 60 ℃, then magnetic valve was opened, and the working medium in the non-pressure-bearing upper inner-liner is progressively heated, and finished auxiliary heating.In heating process, remain working medium in the non-pressure-bearing bottom inner container more than 55 ℃.
Defencive function: system is provided with high temperature protection and low temperature antifreeze function.
Solar hot water heating system of the present invention can be reduced to three kinds of simple systems, is respectively:
(1) have only electrical heating to assist and only be used for the system of heat supply water;
(2) light, electricity, the three-in-one heating of gas and system that only be used for heat supply water;
(3) have only electrical heating to assist and get final product the system that domestic hot-water supply can also heat.
Wherein, the control centre of these three kinds of simple systems is by a concentrated platform control.This platform control promptly can be controlled separately and show, also data wireless can be sent to terminal and show and operation.
Compared with prior art, the present invention has the following advantages:
1) hot water and the cold water that uses in the water pipe because of the pressure-bearing inner bag is all tap water pressure, and the water effect of pressure-bearing solar is arranged, and mixed water is more stable, and bath is washed more comfortable.
2) varying capacity heating has 2-3 hour sunshine that hot water usefulness is just arranged, and is suitable for whole day heat supply water;
3) heating working medium (water) need not often be changed, so can not make the heat pipe and the assisted gas hot-water device lost of life because of long-term fouling;
4) vacuum tube can not cause decrease in efficiency because of fouling;
5) no system long-time running and cause the problem of water poor water quality;
6) system's heating part is the normal pressure operation, so heating working medium water maximum temperature can or not produce high temperature problem above 100 ℃;
7) system pipeline simple installation, the integrated height of control centre is convenient to maintenance management;
8) the system thermal source is based on solar energy, and electricity, gas are auxilliary, has really realized light, gas, the three-in-one effect of electricity, and low-cost, is convenient to promote.
