Weak current College】 【household central air conditioning and the distinction between commercial central air conditioning.

<br> <br> Household central air conditioning <br> <br> Compared to commercial central air conditioning, home users-central air-conditioning with our citizens more closely. Roughly divided, there are residential central air conditioning, indoor and outdoor air .blower plate Tube, pipe three parts. And ordinary split-type air-conditioning, we will run a separate count as part of this is because residential central air conditioning and separate machines, the need to advance in decoration cloth good pipeline. Once the repair .is complete, the pipeline is completely hidden in the decoration. So, you see many users with central air conditioning clean and tidy, decorated wall in no way be damaged, in fact people as early as decoration before calculation. <br> <br> .In addition to the installation order of prior considerations, use household central air-conditioning, you also have to advance in touch with the air conditioning manufacturers. With split air conditioning, you can according to area of let sales people recommend a air conditioning. The .design of domestic central air conditioner is installed all over, including the overall cooling capacity, each room of the outlet location, out of the air volume will have specialized staff for your design. This is why household air-conditioning use than ordinary split-type .air conditioner is more effective. <br> <br> The current residential central air conditioning in the enterprise: foreign Kalee, York, Tring, McQuay, Daikin, Panasonic, Fujitsu, domestic gree, Haier, beautiful, Tsinghua tongfang are more superior. .Including Haier in this month's 7, has launched the latest fifth-generation family of central air conditioning (KVR), its indoor air blower plate Tube has reached 70 × 70cm level than other brands in the indoor part more advantages. <br> <br .> Commercial central air conditioning <br> <br> The structure of the commercial central air conditioning and big residential central air conditioning phase structure of fact. But the reason why areas into commercial home use, mainly due to the power gap formation of refrigeration is .not the same as the form. Household central air conditioner with integrated piston compressors, screw compressors, etc. mainly, while large commercial central air conditioners primarily to split large centrifugal compressors and screw compressors. In addition, the air conditioning system control, automatic control .of the pipeline, air dehumidifier, humidifier, health treatment and other than household air-conditioning much more complex, but also involves individual billing issues. <br> <br> Speaking of which you may not see any longer, since with conditioner million miles .apart, why say that commercial air-conditioner? saying: kill poleaxe? Yes, but killed ox absolutely not chicken. Commercial central air conditioning air-conditioning Enterprise overall strength is the embodiment of good, commercial, home use, of course, no problem .. <br> <br> However, in commercial central air conditioning, especially the centrifugal compressor, our enterprise has been in a passive situation, central air conditioning has been set aside by the United States, York anything Kalee, Tring, McQuay monopoly, .monopoly share as high as 95 percent. Monopoly mainly compressor technology. But this issue has changed this year, gree air conditioning in August of this year launched the first pure homemade centrifugal compressors, to date, the product has been developed for horse number from 1000 .-9000 of aspirin, compressor series. It is understood that the gree's launch of the domestic compressors in technical problems, and after only 8 months, products rotate speed reached more than 6000 per minute. <br> <br> From the series compressor driven .gree new ultra-low temperature more with central air-conditioning, a breakthrough in the work of minus 25 degrees centigrade. Prior to this, the central air conditioner on the market mainly to minus 15 ° c the working standards. Air conditioning in the use .of low-temperature environment, heating capacity depending on the product is subject to decay. According to statistics, internationally recognized as the best heating performance of the central air-conditioning, minus 15 degrees centigrade temperatures, its heating only reted 64 per cent, and .gree ultra-low temperature multi air conditioning at minus 15 ° c, the heating is reted 71%; if contrast normal central air-conditioning, gree ultra-low temperature more with central air conditioning heating effect at least 30 per cent. <br> .<br> Northern winter heating has to coal, natural gas and electric heating, air conditioning, for consisting mainly of use in the northern region is always present "hibernating", because when the outdoor air temperature of up to minus 5 to 10 ° c ., current market household air-conditioning and central heating for air conditioning, it will decay 30 to 40 per cent; and reached minus 15 ¡ .æ, its heating has a 50 per cent, the attenuation of the heating function is not in working condition, the effect is not even-heating and electric heating. <br> <br> <br>.
