Quality is the key? .Advantages and disadvantages of the three standards for household air-conditioning.

For optional air conditioning friends would ask, how to judge whether a good or bad air quality? .The time of purchase we tend to be out of the confusing variety of products, and purchase may also buy some of the concepts will be blind air conditioning, but in the end determine the merits of an air conditioning or the need to proceed from the three standards. .<P Align=left> cooling (heat) content </ P> <P align=left> unit air conditioner running time to remove the heat from the confined space. .Legal Unit W (watt). .</ P> <P align=left> national standards for the actual cooling capacity of air conditioner cooling capacity of not less than 95% of the rated. .Input power: air conditioners for cooling in the rated conditions (heat) power consumption during operation, unit W. .</ P> <P align=left> how to calculate the amount of air conditioning </ P> <P align=left> so-called air-conditioning, "horse" number, originally referred to the input power, including the compressor, fan motor and electric control parts, .cooling capacity of the output power calculation. .</ P> <P align=left> general, a cooling capacity of approximately 2,000 calories, converted into international units should be multiplied by 1.162, it is one of the cooling capacity should be 2000 kcal × 1 · .162 = 2324 (W), where W (watt) means that the cooling capacity, the 1.5 should be to 2000 kcal × 1.5 × 1.162 = 3486 (W), and so on. .Under this situation, the horse was able to determine the number of air-conditioning and cooling capacity, under normal circumstances, 2200W-2600W can be called a, 4500 (W) -5100 (W) can be called 2, 3200W-3600W can be called .to 1.5. .</ P> <P align=left> cooling capacity is determined, you can estimate the cooling capacity according to actual situation, choose the right air conditioner. .Household to consume a larger portion of the cooling capacity, TV, lights, refrigerator and every W (watt) power consumption of cooling capacity to 1 (W), doors and windows must consume a certain direction of the cooling capacity of the east window 150W/M2, .the west window 280W/M2, south windows 180W/M2, north window 100W/M2, if it is appropriate to consider the roof and 西晒 increase cooling capacity. .</ P> <P align=left> EER </ P> <P align=left> also known as the coefficient of performance, refrigeration air conditioner is running, the cooling capacity and cooling power ratio, unit W / W. .</ P> <P align=center> new energy efficiency standards </ P> <P align=center> type </ P> <P align=center> rated cooling capacity (CC) W </ P> <P align = center .> 1 </ P> <P align=center> 2 级 </ P> <P align=center> 3 级 </ P> <P align=center> split </ P> <P align=center> CC .≤ 4500 </ P> <P align=center> 3.6 </ P> <P align=center> 3.4 </ P> <P align=center> 3.2 </ P> <P align=center> 4500 <CC ≤ 7100 .</ P> <P align=center> 3.5 </ P> <P align=center> 3.3 </ P> <P align=center> 3.1 </ P> <P align=center> 7100 <CC ≤ 14000 </ .P> <P align=center> 3.4 </ P> <P align=center> 3.2 </ P> <P align=center> 3.0 </ P> <P align=center> integral </ P> <P align .= center> </ P> <P align=center> 3.3 </ P> <P align=center> 3.1 </ P> <P align=center> 2.9 </ P> <P align=left> noise </ P .> <P align=left> noise generated when the air conditioner running, mainly by internal and external condensate evaporator machine generated. .State regulations, the following 2000W cooling capacity air-conditioning in the indoor unit should not exceed 45 decibels of noise, the outdoor unit is not greater than 55 decibels; 2500W ~ 4500W of split air conditioner indoor unit is not greater than 48 dB of noise, the outdoor unit is not more than 58 .dB. .</ P>.
