选购空调的要点（The essentials of air conditioning） The essentials of air conditioning: 1, output power: refrigeration air conditioning, the standard unit of our country is tile, Japan is a unit, a =2500 watts, 200 Watts / square meter factory requirements, such as 16 square meters room needs cooling capacity of 3200 watts, can buy 32 small machine 1.5 horse. Cooling capacity is too large, the effect is good, but the purchase price is high, the cooling capacity is too small, the purchase cost is low, but the effect is poor, more power consumption. 2, energy efficiency ratio: energy efficiency ratio = refrigeration / consumption power, the same amount of refrigeration machines have 1-5 levels of energy efficiency ratio, respectively 3.4, 3.2, 3, 2.8, 2.6. For example, 1.5 pieces of cooling capacity of 3500 watts, the power consumption of 1 machine is 3500/3.4=1029 watts, 2 machine power consumption is 3500/3.2=1094 watts, visible in the refrigeration output under the same level 1 machine power consumption than 2 machine small 1029-1094=65 watts, is the compressor work for an hour, 1 machine machine less than level 2 level power consumption of 0.065 degrees. 1, the most energy-efficient, but 1 prices are also the most expensive, 5 cheapest, usually buy 2 of the more appropriate, in the promotion of low-carbon economy premise, the following 4 low energy efficiency than the machine, the state will prohibit the sale. 3, frequency converter and constant speed compressor working frequency machine: machine downtime, so there is no fixed speed compressor start and stop the noise, silence is very good, the temperature control accuracy of frequency conversion machine at 0.5 degrees, 2 degrees than the constant speed machine more accurately, so the conversion machine is particularly suitable for use in the bedroom, because the variable frequency machine price your room is not necessary, so the other. Of course, the economic conditions allow or frequency conversion machine is good. The
