In the electricity bill rising, more and more appliances, the monthly electricity bill has become a small overhead in people's daily lives.In order to reduce the cost of their own products in the electricity, all household appliances brand racked Brain juice has developed a lot of energy-saving products, these energy-saving products appear immediately triggered a lot of attention, while in many energy-saving products, air water heater is undoubtedly the most focused product.
As the fourth generation of water heaters, air heaters do not like electric water heaters, as is the direct conversion of electrical energy into heat, but the use of refrigerant from the air to absorb heat, and then through the compressor to convert heat into high-pressure heat, and finally use the converted high pressure Therefore, the energy consumption of air to water heaters is much less than that of electric water heaters, but what are the specifics? Let us take the data as evidence!
Take Rongshida 'inverter air heater' as an example. Compared with ordinary fixed frequency air heater, inverter air heater can have more inverter, which can be used to adjust the working range of the compressor. The equipment can operate at 15Hz ~ 120Hz operating range, the maximum heating capacity of up to 5700w, water heater energy efficiency is as high as 4.22, consume 1kw power, resulting in 4.22kw of heat; and electric heat pipe to produce hot water heater, heating energy efficiency is not To 1.0, only a quarter of the air to water heaters.
In general, a person needs about 50 liters of hot water a day, and most households have a resident population of less than 4 people, so the amount of hot water required for a day is about 200 L. Therefore, here 200L is used as a standard Calculated 200L hot water, the water temperature rose from 20 ℃ to 55 ℃, electricity 0.6 yuan / kWh in accordance with the calculation, the electric water heater needs 1876 yuan, liquefied gas water heater needs 1676 yuan, natural gas heater 845 yuan, solar water heater 592 yuan, but With air to the water heater but only 438 yuan.
More importantly, the general service life of electric water heaters up to 8 years, and air to water heaters can reach 10 to 15 years, the service life is almost double the electric water heater, so have an air to water heaters, not only every year Can save a lot of electricity, you can also 'a Taiwan as two'.
