An efficient heat pump water heater using air heat source won the first prize of six inventions in 2005. Environmental protection products recommended by the state are also a "dark horse" concerned by domestic water heater industry. With the efforts of Mr. Zhang Shaowei for many years, this product has entered people's lives in full swing.
This new type of water heater consists of a heat pump host similar to the outdoor unit of an air conditioner and a large-capacity pressure-bearing thermal insulation water tank. Its installation is not limited by buildings or floors, and its use is not limited by climatic conditions. It can be used as a hot water supply center for families and a centralized hot water supply for units. Due to the adoption of new patented technology in all aspects of the environment, this product is not only safe and comfortable, but also environmentally friendly and energy-saving. The actual usage fee is only equivalent to 1/4 of electric water heater and 1/3 of gas water heater. Mr. Zhang Shaowei said that if the water in the 150 liter water tank is heated to 65oC, it will consume 2 kWh in spring and autumn. If the low-price electricity price is adopted, it only needs 0.6 yuan money, and it will be stored in this water tank. If you take a bath with a faucet, the water heater can continuously supply hot water. Experienced users can set the hot water temperature at 45oC, and the operation of the water heater will be more energy-saving!
Air energy is a kind of low-grade energy that exists widely, is given equally and can be used freely. After the energy level is improved by heat pump circulation, it can be used to heat domestic hot water. Because one electric energy can absorb three parts of air energy and supply four parts of heat energy to heat the hot water system, it is a new energy-saving and environmental protection technology with great development and application potential and great practical value. In addition, the air energy heat pump water heater fundamentally eliminates the potential safety hazards such as electric water heater leakage, dry burning, harmful gas generated when gas water heater works, overcomes the shortcoming that solar water heater can not work in rainy days, and has many advantages such as high efficiency, energy saving, safety and environmental protection, all-weather operation, convenient use and so on. In line with the strategic policy of sustainable development of energy, society and environment in China, it will become the most competitive new generation water heater product in China, providing safe, convenient and cheap sanitary hot water for urban and rural residents.
! Introduction: The arrival of a new generation of heat energy and air source water heaters can be said to be a major breakthrough and innovation in the field of heat energy.

1.wD How does the air (heat pump) water heater work?
Through the operation of the compressor system, the heat in the air is absorbed to make hot water. The specific process is: the compressor compresses the refrigerant, and the compressed refrigerant with increased temperature passes through the condenser in the water tank to make hot water. The refrigerant after heat exchange returns to the compressor for the next cycle. In this process, the heat of the air is absorbed by the evaporator and introduced into the water to produce hot water. This new generation of water heater heated by compressor air is air (heat pump) water heater. WD air (heat pump) water heater is just such a product. This is the working principle of wD air (heat pump) water heater.
What are the advantages of wD air (heat pump) water heater?
"safety+saving money+comfort+environmental protection":
1, safety: no gas, no waste gas and no "gas poisoning"; There is no need to use an electric heating rod for heating, so there is no danger of electric leakage, which protects the health and safety of family members.
Air energy 2, saving money: COP value greater than 3, high energy efficiency ratio, absolutely saving electricity and money. It can save 2/3~3/4 of the electricity fee, or 1/2~2/3 of the gas fee and the auxiliary heating fee of the solar water heater.
3. Comfort: wD patented technology-indirect over-current heating, automatic constant temperature and constant pressure water supply, never hot or cold when using hot water, hot water has pressure and good comfort. All-weather and year-round water supply makes up for the embarrassment of solar hot water system in rainy days, at night, when there is no sunshine and ice.
4. Environmental protection: The cold air discharged from wD air (heat pump) water heater is conducive to lowering the room temperature.
3. Why does 3.wD air (heat pump) water heater save electricity?
Compared with coal-fired boilers, oil-fired boilers, gas-fired boilers and electric water heaters, heat pump water heaters have the highest thermal efficiency.
The efficiency of oil-fired boiler is 65%-75%, that of electric water heater is 70%-80%, and that of heat pump is 300%-500%.
Because the thermal efficiency of heat pump water heater is as high as 300%-500%, the cost of preparing hot water is extremely low, which will naturally save electricity. Other heat pump products also save electricity, but what is the difference?
4. Does 4.wD air (heat pump) water heater have other functions?
WD air (heat pump) water heater integrates the functions of hot water supply, heating, dehumidification, cooling and air filtration.
Hot water is automatically provided 24 hours a day, rain or shine.
Efficient dehumidification, the maximum dehumidification capacity is 6 ~ 8kg (wD-230) every 24 hours, and the effect is obvious in rainy days;
If the ambient temperature is lowered, the temperature in a 6-square enclosed space can be lowered by 4-6℃ (WD-230);
Filter indoor air, and the effect is more obvious when installed in the kitchen.
Additional heating accessories can increase the indoor temperature by more than 5℃ in winter, making study, entertainment and sleep more comfortable.
Verb (abbreviation of verb) What are the requirements for the working environment of wD air (heat pump) water heater?
Whether it is cloudy or sunny, day or night, as long as there is air, hot water can be made. Take wD-230 as an example, at room temperature, it can generate 180L hot water every hour. But when the weather is cold and the ambient temperature is low, it will drop slightly.
6. What are the installation requirements of 6.wD air (heat pump) water heater?
It can be installed in bathroom, kitchen, enclosed balcony, garage, stair corner, storage room, attic, basement and even living room, especially kitchen. Because the air in the kitchen is not good and humid when cooking, installing wD air (heat pump) water heater in the kitchen will greatly improve the air quality in the kitchen and reduce the temperature in the kitchen.
7.wD air (heat pump) water heater can't enjoy other functions when installed on the balcony due to the limited room space?
If cold air leaks from the open balcony, residents in small rooms can't enjoy other functions. But only the hot water function is more electricity-saving, money-saving, safer and more convenient than gas water heaters, electric water heaters and solar water heaters. In order to achieve the best effect, we suggest that if the house is small and needs to be installed on the balcony, the balcony should be sealed with aluminum alloy before installing wD air (heat pump) water heater, so that air and indoor convection can enjoy other functions and be isolated from outdoor noise and dust.
Eight, wD air (heat pump) water heater if the operation and work?
Computer automatic control, without manual operation. When installing for the first time, it must be filled with cold water (there is water flowing out of the water outlet). It takes about 3 hours for cold water to rise from 25℃ to 55℃, with an average hourly increase of about 10~20℃ (it takes about 3~4 hours for cold water to rise to 55℃ in winter). When the temperature reaches 55℃, it will automatically stop, and other additional functions will also stop. When using hot water, when the temperature in the water heater drops to 45℃, the water heater will automatically start to make hot water, and it can continuously produce hot water of more than 120~ 170 liters per hour (the amount of self-made hot water per hour will be different according to different models). When the water temperature reaches 55℃, it will automatically stop and prepare to provide hot water for others to use. Cycle after cycle, cycle after cycle.
9. How many people can 9.wD air (heat pump) water heater serve at a time?
It will stop automatically when the temperature control setting reaches 55℃. With hot water, cold water will enter. When the temperature drops to 45℃ (which can be set at will), the system will start automatically, and it can continuously generate 45~55℃ hot water 100~700 liters per hour (depending on different products). According to the test, the temperature of shower water per person needs 42℃ and the amount of hot water is 40~50 liters. WD air (heat pump) water heater can continuously provide showers for more than 3 people at a time. However, the normal three-person shower time should be 1 hour, so hot water can be replenished for more people to use.
