subject: Universal Air-conditioning Business Of Small Horse-drawn Cart Suffering From Fear Of Addiction [print this page] In order to pursue energy-efficient air conditioning, many companies is a commonly used "mini horse cart" means to a low-power high-volume air conditioner compressor cooling, so that you can achieve "a high value of the energy efficiency of air conditioning, refrigeration capacity is guaranteed", but it will bring direct consequence of "bad effects of air conditioning and heating, greatly shorten the life of the product."
Last week, an air conditioning company told reporters that since last year, the national implementation of the "subsidy policies to promote energy-efficient air-conditioner", a number of enterprises in order to produce "low cost, energy efficiency target" of energy-efficient air-conditioning, taken with a small power refrigeration compressor to produce a large volume air conditioner means. Thus, not only energy-efficient air conditioning can significantly reduce the market price, companies also receive an additional subsidy of 300 countries? Ranging from 850 yuan to promote funds.
The source also disclosed that some companies now operate general approach is to use a small one compressor (22 machines, 23 machines) producing a (25 machines, 28 machines) the air conditioning, compressed with a small 1.5 machine (32 machines, 33 machines) producing a (35 machines, 36 machine) air-conditioning. Small number of enterprises may even use an air conditioner compressor 1.5.
General practices to improve energy efficiency?
One in the past 10 years air conditioning enterprise technology R & D engineers said, the market
Sell Those with "small horse cart" of energy-efficient air-conditioning, 3? 5 years will not be any major quality problems. However, fatigue has been in the work of the compressor stage will ultimately affect the life of air conditioning, as little as 3 years up to 5 years. Meanwhile, within the controller
Electronic Components of consumption will accelerate. Previously, the industry recognized the air-conditioning service life of 10? For 15 years.
Reporter noted, as early as three years ago, each of the fixed-frequency
Air conditioning energy efficiency The upgrade on the existence of different views. With
Hisense Proposed to represent the energy efficiency of enterprises rose 2 directly aimed at promoting the reverse
Inverter air conditioner Popularity. The companies represented by Gree rose to 3 is recommended because it is the dehumidifying capacity of 1,2-grade air conditioning, heating and poor results.
Energy-efficient air conditioning for why there is a "dehumidifier and heating effects of poor", then the enterprises did not explain why. The source pointed out that a 3500 watt cooling capacity of 1.5 foot air-conditioned, if only by 1.2P compressor, so air conditioning will reduce the input power, and through the heat exchanger and air conditioning system matching and optimized on air conditioning cooling capacity can be guaranteed. As the value of the energy efficiency of air conditioning cooling state is in the actual cooling capacity and the actual input power ratio, improved energy efficiency can not guarantee air conditioning heating air conditioning effect.
China Home Appliances Research Institute said an expert from the Department of large household appliances, which is currently set frequency to enhance the energy efficiency of air conditioning, there are three solutions: the first is using energy-efficient compressor, the second is to expand the area of air-conditioning heat exchangers, and the third is the overall air-conditioning system Optimization of matching. And related businesses have pointed out that the first two solutions will increase production costs, the latter solution requires a high technical level, at this stage for many domestic enterprises, are clearly not applicable.
A compressor corporate marketing officers said factory output of high-performance compressors little, basically no effective air conditioning compressor manufacturers all procurement orders, just some small orders. However, the market has emerged a large number of energy-efficient air-conditioning, it is hard to understand.
Enterprise policy dependency fear of suffering
Industry observers point out that some companies see the policy in the great feature driving the market, it created a dependency on the policy, which is very scary.
From Energy Huimin
Policy was announced, many air conditioning companies announced cut-off 2 the following products, a comprehensive transformation of energy efficiency.
