An Attempt to Integrate Solar Water Heater with Building--Talk about Balcony-type Vacuum Tube Solar Water Heater

2 Product Programs An attempt to combine solar water heaters with buildings * Talk about balcony-type vacuum tube solar water heaters Beijing Soyang Science and Technology Development Co., Ltd. Han Peixue reform and opening up. People's lives have been continuously improved. Sanitary bathing facilities are no longer an elusive luxury. Energy-saving and safe solar water heaters are increasingly favored by modern families. However, domestic solar water heaters, such as flat-bed type and boring type, cannot survive winter in China. The utilization rate is too low for the whole year. Electric and gas water heaters are easy to use. However, the cost of energy is high, and life safety is also endangered if it is improperly installed or used. Many people are discouraged. then. Vacuum tube solar water heater came into being.

Vacuum tube solar water heaters can be installed directly on the balcony. Winter is resistant to cold, and summer can resist crickets. It can be used all year round. At present, the overall vacuum tube solar water heater installation method popular in the market follows the flat-type solar water heater, and its advantage is good lighting. Full heat exchange. But its shortcomings are also obvious: Slope mounts ride on the ridge. The construction is more difficult: the average floor area of ​​high-rise residential buildings is small, and the water heaters are often installed in every household: water tanks. The collector is directly exposed to the roof. Heat loss is too high. The water heaters in the house are set to have a uniform lengthening and winter freezing: installation. It is not convenient to repair the climbing on the wall. Also trampling on the roof, accidentally destroying the waterproof layer, some building design and property management departments do not welcome this solar water heater installation mode.

At the Ministry of Construction, a solar water heater review meeting. Architects proposed the development of a new solar water heater. At least change the current single installation mode. Market demand is the goal pursued by the company. Beijing Suoyang Technology Development Co., Ltd. fully listened to the opinions of users and brainstormed. Repeated tests, developed a balcony type vacuum tube solar water heater. The open-air test of the solar thermal utilization equipment inspection station of the National Energy Standardization Inspection and Consulting Center showed that. This type of water heater has an average efficiency of 46.5% in winter and an average heat loss coefficient of 1.13%. The main performance indicators are better than the current national standards. The balcony-type vacuum tube solar water heater is divided into two types: wall-mounted and mosaic-type. It is compared with the overall vacuum tube solar water heater. The structure has a distinctive personality. In particular, there have been breakthrough changes in the installation location on the building.

Collector is made of light + truss. The manifold/reflector and vacuum tube are compact and delicate. The upper and lower pipes of the manifold are arranged diagonally. The tube head is at one end, which is not only conducive to the exchange of cold and hot water convection, but also beautiful. Easy to install. The total weight of the collector after adding water is about 4-50kg. If the heat pipe vacuum tube is lighter in weight, it does not violate the design requirements of residential balcony load and inclined thrust. Water tank capacity 60-100L (different due to the size of the lighting surface), can be hung under the squat of the bungalow, or installed on the side wall of the balcony of the building. It can also be placed in the bathroom. The collector and the tank are connected by a heat pipe. The fluid in the device can be naturally circulated, and it can also be equipped with a miniature thermostat. Automatic watering. Constant temperature water storage, water temperature set arbitrarily. Adjustment, simple operation. With constant temperature and water release, no matter how strong the solar radiation is on the day. R can be bathed with water. Thus overcoming the problem that some solar water heaters cannot be used because the temperature of the water in the tank is too low due to insufficient solar radiation. Wasted water. In addition. Because of the constant temperature and water storage, the collector water reaches the set temperature and is stored by the cold water to the water tank. In the hard water area, fouling can be avoided or reduced, so that the collector can maintain a higher collector efficiency. And delaying the aging process of seals and other components.

+ Has: loss of small water production embryo 1 balcony type vacuum tube solar water heater collector placed in residential sunny shelter. The pipe that needs to be insulated is only about 2 meters. The water tank is installed in the enclosed balcony or in the bathroom, and the heat loss is compared with the overall solar water heater that is exposed on the roof as a whole. After 24 hours, the temperature of the water in the tank is high. The balcony-type solar water heater is equipped with a thermostat. As the hot water in the collector reaches the set temperature, it is instantaneously poured into the tank by cold water. Therefore, the heat loss during the slow exchange of the natural circulation of the fluid is greatly reduced. Therefore, the relative increase in hot water production. According to actual measurements, the self-controlled balcony-type vacuum tube solar water heater is compared with the natural circulation solar water heater with the same lighting area. Hot water production can be increased by 5~8%. The book is properly installed and the materials are maintained. The maintenance type is integrated with the vacuum solar water heater installed at the roof of the house. The pipeline is generally introduced into the bathroom through the ventilation channel at the roof. Two households can still install. If all households are installed. Not only can the air ducts not accommodate the pipelines, but the heat collectors are no matter how they are placed, and the average pipeline for each household will not be less than 15 meters. It is difficult to keep warm. The balcony type vacuum tube solar water heater line from the balcony to the bathroom. The total length is less than 1 meter, which can save a lot of installation materials. Currently using aluminum-plastic composite pipe or cross-linked polyethylene pipe, saving labor and materials. Aesthetic health.

The installation mode has changed. Maintenance and repair are also convenient. In northern China, little rain occurs in winter. If the dust on the surface of the vacuum heat collection tube is not removed in time, the light transmittance of the vacuum heat collection tube will be reduced, and the heat collection function of the heat collector will be affected. The balcony type vacuum tube solar water heater. No balcony type vacuum tube solar water heater has many advantages mentioned above. But we don't say anything. It is installing holes through walls in existing homes. Non-professionals are not allowed. It is expected that the architects can draw a line from the balcony to the bathroom while designing the house, and embed a 1-meter pipeline. In the future, many construction materials will be saved for installation.

In general, balcony-type vacuum tube solar water heaters are currently environmentally friendly and energy-saving products that combine well with buildings in solar water heaters.
