The operating sound of the outdoor unit of the central air conditioner is comparable to that of the traditional air conditioner, and the excessive noise of some central air conditioners is not only a product problem, but also may be unreasonable in design and installation that does not meet the specifications.
Double carbon is a two-stage carbon reduction target proposed by China (referred to as the double carbon strategic goal). Carbon dioxide emissions are striving to peak in 2030, and to achieve carbon neutrality by 2060, to achieve this goal
Recently, the Ministry of Finance issued a "notice on the advance of the 2021 air pollution prevention and control funds budget", the annex clarifies the list of pilot cities and the amount of funds for the 2021 winter clean heating pilot subsidy funds in the northern regions, the total arrangement of 7.34 billion yuan of clean heating pilot subsidy funds in 2021.
Starting from the second half of 2020, the soaring price of raw material copper is destined to be one of the major hot spots in the industry. As of the end of December 2020, the price of 1# copper reached 58,000 yuan per ton, and the development momentum went straight to 60,000 yuan per ton. On January 8, 2021, the price of 1# copper finally broke through the 60,000 yuan per ton mark, reaching 60,420 yuan/ton, an increase of 990 yuan/ton from the previous day. In addition to copper, the prices of steel, iron, aluminum, and plastics have also maintained a high growth trend, which has once again brought enormous pressure on the production costs of the entire manufacturing industry.
Each indoor unit has an air supply and a return air outlet, air circulation is more reasonable, the indoor temperature is more uniform, can maintain a constant temperature of ± 0.5 ℃, the human body feels more natural and comfortable, especially the fluorine system central air conditioning, comfort is very high; and the traditional household wall-mounted and cabinet machines, prone to airflow dead ends, indoor temperature difference is obvious, easy to get air conditioning disease.
In the past two years, with the northern coal change and the southern market consumption upgrade, air source heat pump floor heating and air conditioning two combined supply has emerged. The fundamental reason for the market change is that consumer demand for heating and cooling has been upgraded from a functional demand to a comfort-oriented demand. Driven by the overall consumer upgrade, air source heat pump floor heating and air conditioning technology has been favored by more and more consumers because of its comprehensive advantages in comfort, energy saving and environmental protection, and the market size of the two combined supply systems is growing at a fast pace of more than 200%.
Air energy heat pump units have the advantages of energy saving, environmental protection, etc., and are now widely used in the field of heating. This kind of air central heating equipment host has a characteristic, that is, the power of the host and circulation pump are very large, and the resulting noise problem can not be ignored.
