Supply heat, heating, cooling, air conditioning can't do things, air source heat pump can be done

In life, if you want to take a shower, we need to water heater; If you want to cooling, we need air conditioning; If you want to keep warm, we need electric heater. But have you ever thought, with the development of science and technology, to realize heating, refrigeration and heating, now actually need only one device can, it is the air source heat pump.

All around us, in fact, air source heat pump can be seen everywhere, but because most people lack the understanding of this product, is often seen, also did not realize that it is the air source heat ump. As a professional heat pump suppliers ，we can tell you that air source heat pump could be divided into many products, such as changes in temperature double heat for heat pump, directly heat pump, and can provide heating + hot water + cooling heat pump, we usually call it the full effect heat pump or trigeneration heat pump.

Trigeneration air source heat pump can rely on the inside of the heat pump refrigerant, the heat from the outside world, and then through the compressor power consumption of air source heat pump work, finally will have a hot water heat flux into the cold water. This way of heating ingenious use of the free calories in the air. A high heating efficiency. We know the electric water heater, heating efficiency is only about 95%. The air source heat pump heating efficiency can reach 400%. Air source heat pump hot water produced will save electricity more than electric water heater, ideally can 75% energy saving than the electric water heater. 

Winter heating electric heater at ordinary times, we can only provide a small area of the heating, the coverage of small, local temperature is too high, comfort in general. And the electric heater is coverts electrical energy into heat energy, power consumption is big. Air source heat pump heating is very simple, installed heating the end of the line. Common have a fan coil units, at the end of floor heating pipe and air source heating floor machine. 

Air source heat pump to provide hot water, hot water along the pipe to the end. If it is hang a wall to install fan coil units, from the sky blow out hot air for heating.If floor heating pipes, it is depend on the hot water flow in the pipe produced by thermal rediation for heating. If is the air source heating floor machine, hot water can be transformed to hot, blow out from the ground to keep warm. This end, several kinds of heating need hot water temperature is not high, are below 50℃. Air source heat ump can consume small amounts of electricity to produce more than 55℃ hot water, both match each other, high energy efficiency. 

Air source heat pump can refrigeration, but also for the cause of the refrigerant. In summer, heat pump can be like air conditioning, refrigerant is used to carry heat, transferring heat transfer from the interior. But with the air conditioning is different is that the air source heat pump in cooling, can also through the way of heat recovery for making hot water. So our summer cooling at the same time, also have the hot water can be used to take a bath.

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.

Air source heat pump floor heating is introduced
