Description

A kind of solar energy and the complementary heating system of gas-heating water heater
Technical field
The present invention relates to a kind of heat supply process, particularly a kind of solar energy and the complementary heating system of gas-heating water heater.
Background technology
The characteristic of solar energy source is enormous amount, inexhaustible; Acquisition is convenient, conversion ratio is higher; But timeliness, seasonality are stronger.When summer, solar energy source density is the highest, reaches winter minimum, and thus the heat that obtains in the winter time of the solar energy system of same area is minimum.If the heating system of using it for, its collector area will reach about 1/4th of heating area, if the enclosed structure of building does not reach power conservation requirement, the area needed can be larger.The initial cost enormous amount caused thus, is not reasonably accepting within scope.Chinese scholars, when carrying out the research of solar low-temperature hot water floor radiant heating system, all show that winter solar can provide the heat load of 30% (winter, average sunshine time got 8 hours).Due to the impact that it is subject to weather, the natural conditions such as round the clock, non-fine day (especially winter) solar energy is insufficient, and the water temperature that hot-water heating system provides is lower, and load is difficult to ensure, utilizes solar-heating to be just restricted completely.
Gas-heating water heater, appears at Europe the 1950's, has the family of 70% to use independent individual heating mode at present in Europe, and wherein the family selection of 75% uses gas-heating water heater.The nineties in 20th century, gas-heating water heater starts in China's application, and development was swift and violent in recent years.Gas-heating water heater can be the apartment of about 300 ㎡ or villa provides separately heating reservoir and hot water for life.After installing indoor thermostat additional, the temperature in different room can be regulated; Install timer additional, predeterminable start-up time; Also metering heating can be realized.The expense such as boiler room, heat supply network is eliminated in heating, easy to operate, safety and environmental protection.
Adopt gas-heating water heater to provide heating and domestic hot-water simultaneously, the power that gas-heating water heater answers selection and comparison high, but underload duty can be in for a long time when heating, therefore can reduce the service efficiency of gas-heating water heater, and then affect the service life of gas-heating water heater.
As pure consumption gas equipment, the prerequisite that gas-heating water heater is met consumers' demand necessarily will consume enough combustion gas, thus brings the contradiction of comfortableness and economy.In the face of such situation, gas-heating water heater manufacturer constantly improves properties of product on the one hand, controls to practice every conceivable frugality consumption from equipment; Be exactly advocate behavior energy saving in addition, realize energy-conservation from the angle of user's occupation mode.
In recent years, people start eye progressively to turn to energy saving of system again, be joined in a system by gas-heating water heater and other power consumption or powering device, such as, except directly providing except heating, the equipment such as air-conditioning, heat pump, solar energy that also can be provide auxiliary thermal source.Rely on perfect control system to give full play to the advantage of each equipment, maximize favourable factors and minimize unfavourable ones, finally realize the optimization of the energy, reach the object reducing wastage in bulk or weight.
The heating of domestic hot-water is carried out and heating has respective limitation by our known simple employing solar energy of above-mentioned analysis or gas-heating water heater.As both combined, then can give full play to respective speciality, realizing having complementary advantages, finally reaching energy source optimization, the multiple effect such as reduce environmental pollution, reduce that user economy is paid.
Solar water direct heating in patent 200820103475.3 (the solar energy auxiliary warming of radiation heating), cannot ensure water quality, cause corrosion to heating terminal, reduces service life, and easily frost crack pipe occurs winter; Solar water direct heating in patent 200820201588.7 confession of the band solar energy (warm up hot water two purpose type gas-heating water heater), water quality cannot be ensured, corrosion is caused to heating terminal, reduce service life, and winter frost crack pipe phenomenon easily occurs, domestic hot-water's heating water is used with, water quality cannot be ensured, solar water directly enters gas-heating water heater heating simultaneously, easy fouling and clogging pipeline, corrosion gas-heating water heater; In patent 200910062283 (solar ground heating system), domestic hot-water's heating water is used with, and fails to solve hot water preferentially use problem sequentially; In patent 201010206216.5 (solar gas integrated heating device), heat-accumulator tank adopts multiple heat exchange coil, affects heat exchange efficiency, and cannot ensure heat stability while that gas-heating water heater being lower to heating water tanks efficiency; In patent 201020129575.0 (solar energy and gas-heating water heater are in conjunction with supplying hot water and heating plant), heating most cases only relies on gas-heating water heater, and the utilization rate of heating to solar energy is lower; In patent 201020243754.7 and 201120232330.5 (the complementary heating system of solar energy, gas-heating water heater), domestic hot-water's water temperature cannot meet the demand of user's higher temperature, solar water directly enters gas-heating water heater heating, easy fouling and clogging pipeline, corrosion gas-heating water heater, heating is not yet in effect utilizes solar energy; In patent 201120281740.9 (solar energy wall-mounted gas boiler heating device), domestic hot-water's water temperature cannot meet the demand of user's higher temperature, and heating is not yet in effect utilizes solar energy; In patent 201210330458.4 (a kind of solar energy and combustion gas each door type combined heating system), domestic hot-water's heating water is mixed, and cannot ensure water quality, heating water temperature arranges too high, is unfavorable for energy-conservation; Reckon without in patent 201310514364.7 and 20132066628.0 (a kind of solar energy and condensation-type gas-fired heating water heater combined heating system) that solar irradiation is lower, domestic hot-water's demand is higher causes water tank temperature, heating water supply leaving water temperature too low thus occur that heating water carries out inverse situation about heating to water tank, water storage box complex structure simultaneously, is unfavorable for maintenance.In patent 201320054166.2 (vacuum pipe solar and fuel gas combined heating system), heat-accumulator tank adopts multiple heat exchange coil, affect heat exchange efficiency, and cannot heat stability be ensured the while that gas-heating water heater being lower to heating water tanks efficiency; In patent 201320062466.5 (a kind of tabula rasa solar energy and fuel gas combined heating system), heat-accumulator tank adopts multiple heat exchange coil, affect heat exchange efficiency, and cannot heat stability be ensured the while that gas-heating water heater being lower to heating water tanks efficiency; In 20140556891.4 (a kind of solar energy wall-hung boilers), domestic hot-water is not yet in effect utilizes solar energy, solar water directly enters gas-heating water heater heating, easy fouling and clogging corrosion of piping gas-heating water heater, easily there is frost crack pipe phenomenon in winter.
