Question:

What is the best air conditioning performance.

What is the best air conditioning performance.

Answer:

The basics of air conditioning of choose and buy: The output power of 1, refrigerating capacity, air conditioning, and must choose according to room size, the effect can be ensured, and manufacturer's request for an average of 200 watts/square meters. 18 square meters room, for example, requires the capacity 3600 watts, can buy a standard 3500 watts of machines on the market, or 35 machine, or 1.5 machine. With two digits in the type of air conditioning, KFR35GW / * * *, for example, is the machine capacity 3500 watts. Horse is the input power unit, it with simple conversion formula between the output power of 1 = 2500 watts refrigerating capacity. Refrigerating capacity choice is the main performance of air conditioning, refrigerating capacity partial bigger effect is good, the capacity is too small, low cost, but the effect is poor, more power consumption. Refrigerating capacity is basically hang up within 2 horse, more than 2 horse is basically a ark.

Eer level: the energy saving of air conditioning, the machine type with the Numbers below. Eer = refrigerating output/input power, the refrigerating capacity of the machine, the same old standard before June of this year has eer grade 1-5, 3.4 3.2 3.0 2.8 3.2, the new standard after June 1-3 grade 3.6 3.4 3.4. 1.5 horse machine refrigerating capacity is 3500 watts, for example, level 1 machines consumed power is 3500/3.6 = 976 watts of energy efficiency, the machine level is 3500/3.2 = 1094 watts, the consumption of grade 1 machine than 5 small 1094-976 = 1094 watts, that is to say, the compressor working continuously for an hour, a level 1 machine is less than level 3 machine power consumption 0.118 degrees. Level 1 machine is the most energy saving of energy efficiency, but also the most expensive price, think in terms of price, usually buy 2 level is moderate. Above is the constant speed machine can effect comparing, frequency converter can effect comparing is 1-5, respectively, 5/3.0, 4/3.4, level 3/3.9, level 2/4.5, level 1/5.2, also buy 2 levels of price more appropriate.

Variable frequency and constant speed machine: the working principle of the frequency converter compressor is always start non-stop, through different rotation speed to output different sizes of cold/heat, cold/heat, constant speed machine is a constant output depends on the compressor start and stop to control the temperature. The greatest characteristic of frequency converter, therefore, it is quiet, no compressor start and stop the mechanical noise, 2 it is accurate to 0.5 degrees, the temperature control and constant speed machine control range is 2 degrees, so the frequency conversion machine is especially suitable for use in the bedroom. Due to the frequency changer the price is expensive, decided to other room whether choose according to economic conditions. About energy-saving frequency converter, frequency converter with constant speed machine working mode is different, can't absolutely more energy-saving, frequency converter is used more long time to reflect and energy saving, so the energy-saving sex just select one of the reference factors of frequency converter, is not the main factor. Eer level low frequency changer is not as good as level high constant speed machine and energy saving.

Cold/warm function: the general air conditioning usage, type annotation is KFR, KFRD, if you don't need winter warm, can buy used by machine, model is KF - * * *, a lot cheaper.

Electric auxiliary heating: now in the market of household air conditioning heat pump, this kind of air-conditioning system under the mode of making the machine is in refrigeration, when the environment temperature is less than 5 degrees, the temperature of the heat exchanger outside the machine in sub-zero frozen, need frequent downtime frost, making the properly. So the air conditioning is not suitable for use in north China region heating during the winter. In order to make up for the lack of this feature, many machines with an electric auxiliary heating function. Electric auxiliary heating is actually a set of independent electric heating device, and automatically start when the machine downtime frost, maintain warm air conditioning system output, this function is very useful in winter.
