Look at this set of data you know the air source heat pump water heater how to save money

Recently, the air source heat pump water heater caused a lot of friends of the discussion, which was asked: "say air source heat pump water heater than the traditional gas water heater, electric water heaters, solar water heaters are saving, in the end is the province how much?" In fact, This problem only through the specific experimental data comparison, only to know the results.

According to the ordinary family of four daily hot water 200L, the average temperature from 20 ℃to 55 ℃, electricity costs 0.6 yuan / kWh:

   Type of water heater

   Annual fee

Use air source heat pump save money every year

Electric water heater 

  1971 yuan

     1533 yuan

Liquefied gas water heater

  1752 yuan

     1314 yuan

Natural gas water heater

  913 yuan

     475 yuan

Solar water heater

  657 yuan

     219 yuan

Air source heat pump water heater

  438 yuan 

 

Through the above chart data comparison, we can clearly see that for ordinary families, the use of electric water heater is the highest cost, followed by gas water heaters, natural gas water heaters, solar water heaters, the lowest cost is the air source heat pump water heater. Air source heat pump water heater than electric water heater 75% energy saving, compared to other water heaters, in energy conservation occupies an absolute advantage.

 

Why air source heat pump water heater can do so energy-saving? In view of this problem, the air source heat pump water heater professional and technical personnel explained in detail as follows: "air source heat pump water heater from the" evaporator - compressor - water tank - expansion valve "and other devices constitute a circulatory system, the refrigerant circulated in this system Flow in the evaporator in the presence of a large number of low-temperature low-pressure refrigerant, it absorbs a lot of heat in the air, volatile into low-temperature low-pressure gas refrigerant, compressed by the compressor into high temperature and high pressure gaseous refrigerant (usually up to 100℃), into the tank, The cold water heating, while the temperature dropped to minus 20 ~ 30℃, into a low-temperature high-pressure liquid refrigerant, and then through the expansion valve throttle into low-temperature low-pressure liquid refrigerant, back to the evaporator to absorb the heat in the air, so the cycle, The heat transfer will cool the cold water.

Simply speaking, the air source heat pump water heater is not directly used electric to heat the water, but electricity to drive the compressor to work, the most important is to absorb the heat in the air, after the compressor into a high temperature and high pressure gas to heat the water. The thermal efficiency of the electric water heater is 1: 1, while the air source heat pump water heater thermal efficiency is 1: 4, the heat transfer is far greater than the direct heating of electricity heat. In addition, if the air source heat pump water heater with better parts, but also than ordinary air source heat pump water heater more energy efficient.
