More online growth
The booming real estate in 2016 not only boosted the growth of the household air-conditioning market, but also drove the central air-conditioning market. The report of the "Central Air Conditioning Market" obtained by the reporter shows that the capacity of the domestic central air-conditioning market in the first half of this year has reached a record high, exceeding 40 billion yuan. The growth of the market is mainly due to the recovery of the industrial project market and the increase in private investment, resulting in the increase of small and medium-sized projects. The demand for the northern coal to electricity market.
From the perspective of segmentation, the growth of the central air-conditioning market in the first half of 2017 was mainly due to the growth of multi-line. Industry online statistics also showed that online consumer sales in the first half of the year increased by 31.6% year-on-year.
A central air-conditioning industry analyst who did not want to be named told the "Daily Economic News" reporter that home central air-conditioning was favored by last year's real estate policy. In the first half of this year, a small outbreak of the market was ushered in. At present, household central air-conditioning is also eroding some household air-conditioner cabinets. Market.
Huang Guoqiang told reporters that Midea’s central air-conditioning business unit achieved an operating income of 8.2 billion yuan in the first half of this year, a year-on-year increase of 29%. The revenue from multi-line business increased by about 30% year-on-year. In the first half of the year, Midea's home central air-conditioning sales also achieved a 52% year-on-year growth.
Midea Group's central air-conditioning business unit also held a scientific and technological innovation achievement appraisal meeting on August 1st, and the M-ai full-conversion quasi-secondary compression technology and the ultra-low temperature high-efficiency liquid-spraying technology of the flame air source heat pump for the US central air-conditioning MDVS multi-line connection. Identification. Huang Guoqiang told reporters that Midea's R&D investment in 2017 is expected to reach 5% of annual sales, which will be higher than the industry average of 3%. The future of the US central air conditioning will go to the direction of full frequency conversion technology to develop and develop.
European and American brand market share is squeezed
Due to the rapid growth of the multi-connected market in recent years, major brands have “grabbed†the central air-conditioning market. “Many brands are not paying attention to other products now, and they are watching more online.†A person in the central air-conditioning industry told reporters.
According to the "Central Air Conditioning Market" statistics, in the multi-line segmentation field, Daikin and Hitachi still occupy the first and second place in the domestic multi-line market with 21.8% and 16.5% market share, and the US ranks third.
As far as the overall central air-conditioning market is concerned, the market share of European and American brands has continued to decline under the “pinch†of domestic brands and Japanese brands. Statistics from Industry Online also show that the market share of US brands in the first half of this year fell by nearly 2% compared with the same period last year.
“The market share of European and American brands is indeed declining, because the main products of European and American brands of central air conditioners are chillers, but in the past two years, due to macroeconomic factors, China’s large projects have decreased. At the same time, the technology and quality of domestic brands have caught up. In this context, in fact, the prices of European and American brands have declined significantly, and the price gap between domestic brands and American brands has become smaller and smaller. The above-mentioned central air-conditioning industry, which is not willing to be named, The analyst said.
Piezoelectric Discs For Flowmeter Sensor
Piezoelectric ceramic disc
Quick delivery
High performance
Application: flow meter measurement
There are many kinds of USF used in closed pipeline according to the measuring principle, and the most commonly used are propagation time method and Doppler method. Among them, time difference ultrasonic flowmeter is used to measure fluid flow by the principle that the time difference of sound wave propagating downstream and countercurrent is proportional to the velocity of fluid flow. It is widely used in raw water measurement of rivers, rivers and reservoirs, process flow detection of petrochemical products, water consumption measurement of production process and other fields. According to practical application, time-difference ultrasonic flowmeter can be divided into portable time-difference ultrasonic flowmeter, fixed time-difference ultrasonic flowmeter and time-difference gas ultrasonic flowmeter.
Ultrasonic flow-meters use at least two transducers aligned so that ultrasonic pulses travel across the flow of liquid or gas in a pipe at a known angle to the flow.
