Hello, I think that no matter how good the machine is, if it lacks maintenance, the lifespan of the water heater will be significantly reduced. You can follow the fifteen methods and precautions given below for the care and maintenance of air-to-energy water heaters.
1. Users should pay attention when using and maintaining the heat pump unit: all safety protection devices of the unit are adjusted before leaving the factory. Do not disassemble or adjust yourself.
2. Avoid accumulating debris around the device, which may cause blockage of the air inlet and outlet and affect the normal use of the device. The area around the device must be kept clean, dry and well ventilated.
3. The exterior of the finned heat exchanger should be kept clean and free of dead leaves, lint, insects and other easily removed pollutants.To ensure that the finned heat exchanger can work efficiently and maximize performance. . heat exchange.
4. Regularly check whether the wiring of the power supply and electrical system of the unit is firm and whether the electrical components are functioning abnormally. If there are any abnormalities, they should be repaired or replaced in time... ...

On September 3, in Yulin, Shaanxi, the Venus 50 solar-powered drone independently developed by China's first aviation academy was successfully launched to the first time. The “Daystar 50” took off that day at 5:50 p.m. and landed safely at 6:16 p.m. after a 26-minute flight. The aircraft was in good condition, all operations were carried out normally and the first flight was a complete success.
Feature 1:
Feature 1 is that the dronelarge-scale solar powered Venus 50 is China's first ultra-long, low-speed drone with ultra-length/rope ratio, and it is also the first in the world. The first fully electric giant drone with a two-body structure and solar energy as the sole power source. Among them, the biggest advantages of catamaran design are carrying capacity and range. The wings of the catamaran design are longer. The wingspan of the Venus 50 (the distance between the left and right wingtips) is 50 meters, which is equivalent to 60.12 meters of a Boeing 787.
Function 2:< /p> Feature 2 of the Venus 50 is that it has a modular design, which can quickly break down an aircraft in two, or add a module to the fuselage group. And its elongation rate is also very high. “Aspect ratio” is calculated by dividing the square of the wingspan by the wing area. Therefore, a thin wing has an aelongation, aspect ratio and longer flight time. Theoretically, it could survive in the sky for months or even years. But now, the Venus 50 mission lasts seven days. In order to improve the efficiency of photoelectric conversion and avoid atmospheric interference, the Venus 50 solar-powered drone flies in the stratosphere and can reach a maximum height of more than 20,000 meters.
In general, the future is dominated by new energy, and solar drones use the sun's energy to store excess energy in a day's battery. Use batteries for continuous flight at night. and the use of chemical fuelsCompared to airplanes, solar-powered airplanes do not pollute the air and are a truly green and environmentally friendly means of transportation. According to research firm NSR, the market for ultra-high altitude aircraft, such as drones and spacecraft flyingin the stratosphere, will reach 1.7 billion dollars over the next ten years.
