Add knowledge on how to choose air energy water heaters
Look at the professionalism of the brand
Regarding the air energy industry, some brands only make air energy products, and some have transformed from other fields. Some became monks halfway. Therefore, when consumers choose air energy brands and products, they must combine the above two points to judge the professionalism of the brand and the maturity of the technology.
Whether the quality is reliable
An important indicator to judge the quality of air-energy water heaters is to look at the compressor. The compressor can be said to be the heart of the air-energy water heater. Nowadays, the Panasonic brand is used in the use of compressors. Best of all, some in the industry use domestic air conditioning compressors, but the performance and life of the unit cannot be guaranteed.
How about after-sales guarantee
The service commitment period of brands that are well-established in the industry today is: 3-year warranty for the main unit of the home machine and 1-year warranty for the water tank. However, consumers cannot simply trust the warranty period when purchasing, such as whether there is a dedicated person to inspect and repair from time to time, how many hours it takes to respond to a repair report, how many hours it takes for repairs to come to your door, etc.
What are the advantages of functions
When purchasing air-energy water heater products, in addition to comparing the benefits and data related to industry commonality such as energy conservation, environmental protection, and safety (this is the common function and function of all air-energy water heaters) selling point), it is important to comprehensively consider other additional functions of the product, such as daily cleaning, maintenance, intelligent insulation functions, etc.
Is the technology authoritative
The company's technology is recognized by the industry, has a government-recognized engineering technology research and development base, and has undertaken or participated in national-level scientific research projects.
Advantages of air-energy water heaters
Energy saving. Since the thermal efficiency of air-energy water heaters is as high as 3-, which is three times higher than ordinary water heaters, the cost of making hot water is very low, which also saves electricity. . The daily electricity bill of an air-energy water heater is - yuan. Compared with ordinary water heaters, the monthly electricity bill can be saved by about - yuan.
. Convenient and comfortable, it can continuously and automatically supply hot water all day long, no matter whether it is cloudy, rainy or snowy, all year round, which is more convenient than ordinary solar water heaters.
3. High-efficiency dehumidification, the maximum dehumidification capacity is -kg per hour per day, and the effect is more obvious in plum rains and rainy weather, especially suitable for humid southern climates.
. Low noise. The air-energy water heater uses a closed silent compressor and adopts sound-absorbing treatment inside, so the noise is extremely small.
. Environmental protection, because the air-energy water heater does not use gas, it will not produce waste gas, which will not damage the ozone layer. It also saves electricity, and every time it consumes less electricity, it can reduce the cost of power generation. Pounds of carbon dioxide are produced, which can reduce damage to the ozone layer. Therefore, the use of air-energy water heaters can also delay global warming. It can also purify indoor air.
.Safe, air-energy water heaters do not use gas, so the safety hazard of carbon monoxide poisoning can be completely eliminated. Electric heating rods are also not used to heat, eliminating the possibility of leakage. So it is safer.
. It can be used by multiple people. When the temperature control setting of the air-energy water heater reaches ℃, it will automatically shut down. When the hot water starts to be used, cold water will enter. When the temperature drops to a certain temperature, the system will automatically start again. Every hour Can continuously generate - ℃ hot water - liter. After testing, the shower water temperature per person needs to be ℃ and - liter of hot water volume. The air-energy water heater can continuously provide showers for more than 3 people at one time. But normally the shower time for three people will be several hours, so the additional hot water can be used by more people.
.Air source water heaters have a wide range of applications, including hot water for industrial production, hot water for bathing in factories, hot water for preheating for drinking water in hospitals, hot water for bathing in schools or private student dormitories, hot water for showers in company employee dormitories, hotels, etc. Many hotels and guest houses have centralized hot water supply for bathing bases, hot water for bathing bases, restaurant kitchens, beauty and hairdressing industry water, kindergarten campus drinking water preheating for household showers, bathtubs, massage bathtubs, and hot water use. It is especially suitable for mid- to high-rise buildings, villa residents and large buildings. The hot water is used for household floor heating, radiator heating, fan heating, car washing, scrubbing and other domestic hot water.
.The air-source water heater has a relatively large appearance and is required to be installed on the ground or on the roof of a building. It has relatively high requirements for the home environment.
3. The compressor is easy to burn out. Nowadays, air-energy water heaters on the market widely use circulating heating systems. Operating under high temperature and high pressure conditions can easily cause the compressor to age and carbonize. If the system lubrication is not good, it will easily cause the compressor to burn out. causing the compressor to burn out.
. Heat exchangers and sleeve heat exchangers are prone to scaling and cracking, because the outlet water temperature of air-energy water heaters can reach -°C. Water is most susceptible to scaling in this temperature range. If the heat exchanger cannot be cleaned regularly For plate heat exchangers, it will burst. For sleeve and tube heat exchangers, the inner tube will rupture, causing the entire unit to lose function.
