For people who first heard about air energy water heaters, many people are curious. They don’t know that there are such water heaters. In fact, many people are not familiar with air energy water heaters because there are not many people who use them. Today we introduce air energy water heaters to you.
Air energy water heater, also known as “air source heat pump water heater”. “Air energy water heater” absorbs the low-temperature heat in the air, gasifies the fluorine medium, pressurizes and heats up after compression by the compressor, and then converts the compressed high-temperature heat energy into feed water for heating through the heat exchanger to heat the water temperature. The air energy water heater has the characteristics of high efficiency and energy saving. It produces the same amount of hot water, which is 4-6 times that of the general electric water heater. Its annual average heat efficiency ratio is 4 times that of electric heating, and its utilization energy efficiency is high.
Advantages of air energy water heater:
1. Power saving. Since the thermal efficiency of air energy water heater is as high as 300% – 500%, which is 4-5 times higher than that of ordinary water heater, the cost of making hot water is very low and power saving. The electricity charge of air energy water heater is 1-2 yuan per day. Compared with ordinary water heaters, it can save about 70-80% of the electricity charge per month.
2. Convenient and comfortable. No matter whether it’s cloudy, sunny, rainy or snowy all year round, it can continuously and automatically provide hot water 24 hours a day, which is more convenient than ordinary solar water heaters
3. Efficient dehumidification. The dehumidification capacity is 6-8kg 24 hours a day. The effect is more obvious in plum rain and cloudy and rainy weather, especially suitable for humid southern weather.
Disadvantages of air energy water heater:
1. It is easily affected by the surrounding air environment. When the weather is cold and the ambient temperature is low, the amount of hot water produced will be slightly reduced. In particular, it is easy to frost at – 10 ℃, and the unit stops working below – 20 ℃. The problem of defrosting is a difficult problem to be solved at present.
2. The shape of air energy water heater is large, and it is required to be installed on the ground or roof, and the requirements for household environment are also relatively high.
3. The compressor is easy to burn out. Now the circulating heating system is widely used in air energy water heaters on the market. Running under high temperature and high pressure is easy to make the compressor aging and carbonization. If the lubrication effect of the system is not good, it is easy to cause the compressor to be burned out.
The purchase of air energy water heater mainly depends on the following aspects.
1. Look at the brand
Choose the more common professional brands in the market, because the concentration of air energy market is low and the good and the bad are mixed. The manufacturers who used to make solar energy and air conditioning are also selling air energy water heaters, but their R & D and production do not have the production conditions of professional air energy. There are many products today. Manufacturers will go to whichever product they see to make money. Without certain basic technical support, the products they produce will not be guaranteed, especially for new products such as air energy water heaters. Therefore, when choosing air energy water heaters, they must choose professional and brand products.
2. Look at the model
Professional large factories used to have more large-scale projects and models, especially in the cold north, and even enterprises with more model projects in Tibet have more stable products and stronger technology and energy conservation. The constant temperature of the water tank is better. This function takes into account the needs of customers. The constant temperature function can ensure that the water during bathing will not be cold and hot, so as to avoid scalding customers, especially for families with elderly and children. At the same time, it can meet the family’s hot water demand in winter.
3. Look at the weight
It should be a standard equipment. The main accessories are composed of compressor four-way valve, electric control casing heat exchanger, fin heat exchanger, etc. while some manufacturers use virtual standard heat, smaller compressors and heat exchangers assemble equipment, but the direct heat power of the equipment is far from the marked value. Taking a standard 13 piece direct heating equipment (pashw130sb-2-c) as an example, the net weight of the standard brick is 310kg.
