Air source heat pump water heater compare to electric water heater to save money

Guangteng top heat pump manufacturers

Air source heat pump water heater recently more fire, more and more people began to pay attention to this trendy water heater. Which is the most discussed is the energy problem. Some people think that air source heat pump water heater save power, but not save money. But there sare some people who say that the air source heat pump water heater as a whole is to save money. The two sides of the word, who is right?

To discuss whether the water heater energy saving, mainly to see its heating design. Air source heat pump water heater does not need to burn gas as gas water heater, it is somewhat similar to "electric water heater and solar water heater complex." Air source heat pump water heater is the use of refrigerant to absorb the heat in the outside air, and then to drive the compressor to work, after a series of heat transfer process, resulting in hot water. Although the air source heat pump water heater itself is power, but it is only for power consumption for the compressor, rather than the energy into heat. Thermal energy is mainly from the air free access to, so the air source heat pump water heater heating efficiency than electric water heater.

Electric water heater heating efficiency is about 95%, while the air source heat pump water heater heating efficiency according to the temperature changes in the 250% to 400% fluctuations. The general temperature reached 20 ℃, air source heat pump water heater heating efficiency can reach 400%, if it is cold winter, air source heat pump water heater heating efficiency will be slightly decreased.

In theory, the air source heat pump water heater heating efficiency is 4 times the electric water heater, which is 75% energy saving than electric water heaters, electricity is also about a quarter of electric water heaters. So that the air source heat pump water heater energy saving, this view is right. But the province does not save money, which have to convert electricity into actual money to compare. According to the data show that if the daily supply of 200L hot water, hot water heated from 15 ℃ to 55 ℃, air source heat pump water heater is less than 500 yuan a year, while the electric water heater needs more than 2,000 yuan. Daily electricity costs, air source heat pump water heater to a clear advantage to win.

In addition to electricity, the cost of the purchase of water heaters have to come in. A high-end electric water heater, priced at 2000 to 3,000 yuan. A high-end air source heat pump water heater, priced at 6000 ~ 7,000 yuan. On the initial investment, the electric water heater than the air source heat pump water heater cheap about 4,000 yuan, a huge advantage. But the water heater is generally used for many years, so we have to consider from the overall income.

An electric water heater, the service life only 6 to 8 years. Air source heat pump water heater, if usually properly maintained, the service life can generally reach more than 10 years. According to the theoretical value, the two-year electricity tariff gap can reach 1,500 yuan. However, due to different regions of the environment, in order to rigorous, here by a minimum of 1,000 yuan. Air source heat pump water heater use 4 years, the overall expenditure and electric water heater quite. The next few years, due to higher heating efficiency, so more power than electric water heaters.

Villa heating and cooling options have new tactics

Live a spacious villa is the dream of many people’s lives. However, to really enjoy life in the villa, not only to worry about making money, have to choose a lot of thought in the selection of equipment.

Villa with ordinary residential compared to the structure and construction area has obvious differences, the villa as few as a few hundred square meters, a thousand square meters, so that, whether it is cooling or heating, difficulty and ordinary residential phase Bigger than a lot. In the face of such a situation, the villagers are how to solve it? The answer is simple, use air source heat pump.

Air source heat pump is favored for many reasons, but the most important thing is energy saving. Air source heat pump by the evaporator, compressor, heat exchanger and other components, rely on “anti-carnot principle” heating. First through the evaporator to absorb a lot of free air heat, and then pass the heat to the compressor, the compressor will convert these heat into high-grade heat, the final output heating to the room. This way of transporting heat from the air, so that the air source heat pump consumes 1 kWh, you can get 4kw of heat, heating efficiency of 400%, than the traditional electric heating, coal boiler to save a lot of energy.

In summer, the air source heat pump can be switched to air conditioning mode. In air conditioning mode, the air source heat pump can produce cold water, with the fan coil discharge a lot of cold, in order to reduce the indoor temperature. Data show that even if the external temperature up to 30 ℃, air-source heat pump to open the cooling mode, it can also reduce the room temperature to about 20 ℃, the cooling effect is not less than the air conditioning.

Whether it is cooling or heating, air-source heat pumps are known for their comfort. It “water cycle” approach, the air-conditioning, heating delivered to the interior, this mechanism to make the wind more gentle, but also reduces the evaporation of water on the human skin surface, there will be no obvious dry mouth, but will not induce cough , cold and other symptoms, bring is truly comfortable heating, cooling experience.

Not only comfortable and energy-saving, air-source heat pump environmental effects are amazing. Because the air source heat pump uses the heat in the air to heat, the heat pump relies on the electric energy to drive. The heat pump equipment does not consume any coal and natural gas and naturally does not produce harmful gases, which can create a good environment for the villa . Air-source heat pump heating and cooling advantages so much, no wonder the choice of many villa tenants.

Air source heat pump new market - infant swimming pool hot water supply

Infant swimming pool more common in cities, people’s living standards gradually increased after an emerging product. Swimming pool has a professional swimming pool, you can provide just enough comfort for the newborn child’s hot water swimming experience. The opening of a family of infants and young children’s swimming pool, but also to the relevant industrial chain began to be active. Among them, the air source heat pump hot water market as an important device, also ushered in the new development opportunities.

Air-source heat pump by a lot of infants and young children’s swimming pool owner to fancy, there are several reasons, the first to say is safe. Normally, equipment for supplying hot water to buildings includes oil-fired boilers and coal-fired boilers. Both of these facilities have an open flame during the heating process, posing a potential safety hazard. For infants and young children’s swimming pool this place has a demanding safety requirements, it is not so suitable.

Air source heat pump driven by electric energy, through the refrigerant absorbs heat in the air to produce hot water. Heating process, do not consume any fuel, natural gas, the flame does not appear to burn, so completely eliminate fire hazards. Heat pump heat exchanger also uses water and electricity separation design, but also reduce the probability of leakage of equipment at the root causes, has become the safe patron saint of the babies.

Then analyze the cost of air-source heat pump heating costs. In Guangzhou, there are quite a few cases of using the air source heat pump to heat the baby swimming pool. The author has obtained a detailed data from the list below. A baby swimming pool installed a 5P air source hot water unit. The installation cost of the project is about 20,000 yuan or so, which is about 8,000 yuan higher than the nearby swimming pool that uses oil-fired boiler heating.

However, in the subsequent use, the energy-saving effect of air-source heat pump gradually highlights. The use of oil-fired boiler heating, daily consumption of about 30L of fuel consumption, oil prices at 6.7 yuan / liter basis, the daily operation cost of oil-fired boilers over 200 yuan. Air source heat pump, as it is taken from the air, the daily power consumption is only about 20 kWh, commercial electricity price of 1.5 yuan / kWh, count down, heat pump daily operating costs only tens of dollars, far below the oil-fired boiler .

With the increase of newborns, air source heat pumps will also come one after another in the next few years in the market a small outbreak.

Ground source heat pump and air source heat pump how to choose? What's the difference?

Ground source heat pump and air source heat pump popularity, but also so many users in the choice of entangled, do not know which one is good? Do not know how to choose?

Both ground source heat pump and air source heat pump are energy saving and environmental protection heating and cooling equipment systems, which are all systems that utilize advanced heat pump technology for energy conversion. However, their conversion methods are not the same: ground source heat pump is the use of soil heat for energy conversion , While the air source heat pump is the use of air source heat pump technology for energy conversion, but there are some differences between the two.

1. Ground source heat pump more energy efficient, but need to dig wells, the installation needs to have the conditions of drilling, the initial cost will be higher, suitable for villas, schools and other places.
2. Air source heat pump does not require drilling, just need air on it, covers an area of space is relatively small, suitable for high-rise buildings.
3. Ground source heat pump host, end and underground buried pipe systems, and air-source heat pump only the host and the end, the relative operation is relatively simple.
4. Ground source heat pump than the air source heat pump temperature stability, ground source heat pump is the use of soil heat transfer method, the soil temperature is relatively constant throughout the year, and the air source heat pump is the use of air.

Both ground-source heat pump and air-source heat pump are energy-saving and environment-friendly energy systems, each with its own advantages. Users should choose suitable and suitable ones according to their actual conditions to achieve the maximum effect.

Air source heat pump units of defrosting method

With development of the trend of environmental protection and energy saving, the use of air source heat pump is gradually increasing, because in case temperature, air source heat pump in use process to frost phenomenon, affecting the performance of air source heat pump, today the air source heat pump defrosting methods to share with you. 

1. Stop frost: air source heat pump heat exchanger surface frost layer forms, too thick frost layer can reduce heating efficiency of the unit and increase power consumption, unit in this case the runtime also particularly prone to failure. Stop frost is the most convenient forms of air source heat pump units frost simple a way.

2. Reverse cycle defrost: switch the four-way reversing valve, which changes the flow of refrigerant, so as to achieve the effect of evaporator and condenser role exchange, close the fan, through the refrigerant of heat and the effect of the frost. This method is the most common of all the way to frost, frost process faster, improve the efficiency of the air source heat pump units of frost.

3. The hot gas bypass defrosting: open the hot gas bypass valve, turn off the fan, compressor exhaust will arrive through the hot gas bypass valve of liquid receiver, finally into the air cooled heat exchanger of defrosting.This way of defrosting effect is obvious and can not only shorten the time of frost. 

Timely to frost, air source heat pump units can not only improve the heating efficiency of the unit, also can reduce the damage to the equipment, can effectively increases the service life of air source heat pump units. Select the correct defrosting method can not only reduce the frost time, improve the working performance of the unit.

Air source heat pump floor heating and radiator which is better

With the constant change of the weather is cold, people also particular concern for heating, mostly to install heating system at present, the most popular in the market is the air source heat pump heating floor heating and radiator heating, for above two hot heating ways which one is better, here is to analyze the advantages and disadvantages of them and so that everyone can have a full understanding.

Air source heat pump floor heating and radiator, by contrast, both the running principle of basic similar, is through the hot gas send out to realize the rise of temperature, finish heating, but still exist between different, installation of floor heating is in installation is needed before operation, the building is decorated after renovation is difficult when installation, quantity is big, time is longer, so after the installation is not recommended, and the radiator before decorate and decorate after all its installation will not cause any influence, less construction difficulty, installation time is short, convenient and simple. 

Air source heat pump installation, the method is relatively hidden, will not take up too much space, will not affect the beautiful house, and it has obvious advantage that the ordinary floor heating, heating faster when using, heat evenly, comfortable is extremely strong, energy saving effect is remarkable, and the radiator need to choose suitable location to install, will occupy a certain space, so that air source heat pump heating floor had a good choice. 

Air source heat pump floor heating is buried in the ground, is by raising the temperature of low temperature hot water, transfer heat from underground into the air, as a result, the heat from bottom upm confirms to the principle of keeping in good health, and the heat evenly inside the air, the temperature difference is small, comfortable and reliable. Radiator is only a fraction of the concentrated heat is to heat the air around first, and then achieve the purpose of heating by air convection heat transfer, this way of thermal comfort is relatively poor.

For now, the air source heat pump heating is a clean way of heating, with the continuous development of air source heat pump, remarkable achievements in the field of heating, and is used by more and more people, so will gradually become the first choice for heating.

Another advantage is use of air source heat pump running costs are relatively low, it is compared with other heating way, by contrast, it is also in favor of the heating way of the human body health.  

Ten Big Advantages Air source Heat Pump

1, Low operating cost, energy saving effect is prominent. Air source heat pump can save 70% energy compared with conventional products. With gas, electricity and electric auxiliary heating, compared to the solar water heater for the lowest cost, better than solar water heater (with auxiliary electrical heating), is 1/3 of gas water heaters, electric water heater around a quarter. Each power 1 kw can produce an average of 4 kw of heat energy, the same power consumption system, hot water about three times more than in the boiler.
