Further specify indoor apparatus of air conditioner of the present invention below in conjunction with noise contrast test and energy consumption contrast test and have the characteristics of low noise and low energy consumption with respect to single motor indoor apparatus of air conditioner.In these contrast tests, employing be to have the air-cooled cabinet-type air conditioner of two blower fans of two motors, two fan blades and two spiral cases and single blower fan list refrigerator machine of single motor compares.
1. noise contrast test
In this experiment, noise when respectively single blower fan list refrigerator machine being moved with the air-cooled cabinet-type air conditioner of two blower fans is tested, when test contents is the operation of different cabinet-type air conditioners, the peak value of the different frequency section noise that produces, its result such as Fig. 6 are to shown in Figure 9, what X-axis was represented in Fig. 6 to Fig. 9 is the frequency of noise, and what Y-axis was represented is the decibel value of noise.
As shown in Figure 6, the air-cooled cabinet-type air conditioner of single blower fan is when frequency is 840Hz, and noise reaches peak-peak 47.7dB (A)/20.0uPa.
As shown in Figure 7, the air-cooled cabinet-type air conditioner of single blower fan is when frequency is 800Hz, and noise reaches peak-peak 56.4dB (A)/20.0uPa.
As shown in Figure 8, the air-cooled cabinet-type air conditioner of two blower fans is when frequency is 104Hz, and noise reaches peak-peak 46.3dB (A)/20.0uPa.
As shown in Figure 9, the air-cooled cabinet-type air conditioner of two blower fans is when frequency is 800Hz, and noise reaches peak-peak 51.8dB (A)/20.0uPa.
Draw by above contrast, the noise that the air-cooled cabinet-type air conditioner of two blower fans produces when operation is significantly less than the noise that produces when the air-cooled cabinet-type air conditioner of single blower fan moves, and noise reduction is obvious.
2. experiment of energy consumption
In this experiment, respectively the air-cooled cabinet-type air conditioner of single blower fan and two air-cooled cabinet-type air conditioner of blower fan are tested in the energy consumption of freezing and heat in the process, extremely shown in Figure 13 as Figure 10:
Contrast by Figure 10 to Figure 13 as can be known, the air-cooled cabinet-type air conditioner of two blower fans can loss-rate all be higher than the air-cooled cabinet-type air conditioner of single blower fan when operation.
Therefore, as from the foregoing, indoor apparatus of air conditioner of the present invention adopts the fan part of many electric machine structures, whole fan part can be placed on top or the bottom of evaporimeter together with drip tray, utilize at least two low-power machines to reach the operational effect of high-power single motor, can reduce the noise of indoor apparatus of air conditioner effectively, and reduce cost simultaneously, and final assembly is simple.
In addition, adopted the structure of many motors, can also by the mode of different program controlled motor runnings is set,, not open the different capacity during unlatching etc. simultaneously according to indoor different temperature regime as opening simultaneously.
Certainly, technical conceive of the present invention is not limited in the foregoing description, can also obtain many different concrete schemes according to design of the present invention, for example, the quantity of the motor of installing in the indoor apparatus of air conditioner of the present invention, fan blade, spiral case can also be according to different needs and is different, the arrangement mode of motor, fan blade, spiral case except can about be arranged side by side, can also adopt front and back or mode up and down to arrange, all should be included within the described scope of claim such as these changes and equivalent transformation.
