What are the advantages and disadvantages of the central air conditioner and the single compressor in the central air conditioner?
Dual compressor applications are: dual compressors in parallel, or two compressors, each with a separate refrigeration system.Double compressor is equivalent to two grade, so compared with a single compressor, the compressor part load condition, the overall start / stop times will be lower, it is better for the service life of the compressor; the control precision will be good; double grading start will impact on the grid to reduce the starting current of the compressor;If it is double compressor parallel applications, only when a compressor, the condenser is equivalent to using a very large and heat exchanger, and the energy efficiency ratio of the system is very high, very energy saving; but this application should pay attention to oil back design between two compressors;
Dual compressor in low load working state, you can work as a compressor. Save energy relative to single compressor. The single compressor can only be adjusted at its own work. And with intelligent start-up of air conditioning, can be the first single A compressor after the second time, single B, so that the compressor life longer..
Dual compressor cooling power, refrigeration speed faster than single, but the power consumption is also large, if the frequency conversion is better, if not, then frequent start, then higher energy consumption.
Compared with split air conditioners, the main advantages of home central air conditioners are as follows:1, the central air conditioning host less, only need an air conditioning host position can, now the real estate developers consider the overall appearance of the house, often reserved air conditioning host seat is not enough, it is difficult to install split machine.2, the central air conditioner in the machine generally use the wind pipe machine form, and ceiling decoration style matching, and the wind is more soft, will not appear straight blowing people phenomenon.High efficiency 3, central air conditioning, especially large heat exchanger efficiency to change the host at the part load operation is higher, and all in all the air conditioning machine running normally not, more outstanding operation efficiency and energy saving of central air conditioning.Of course, the central air conditioner also has its own shortcomings:1, the product price is higher, especially for installation requirements high.2, air-conditioning machine maintenance is not convenient, especially the heat exchanger is bad, etc., when you need to move the system, you need to break the top repair;3, the overall central air-conditioning life in about 15 years, the latter replacement costs higher.
