Home-Appliances Window Air Conditioners – How To Reduce The Noise Level Perhaps the most widely used air conditioners are the window air conditioners. They are quite popular for heating and cooling in both domestic and commercial premises. The basic advantage of a window air conditioner is that unlike the central air conditioners and the split air conditioners, it fits well in the window giving a good look and it does not occupy any space of the room at all. Moreover, window air conditioners do not need to be shifted every now and then from one place to the other. However, like any other air conditioning equipment, it produces noise, the intensity of which differs with the type and size of the window air conditioners. Constant noise can indeed be very disturbing and distressing to the home and surrounding residents. It is, therefore, advisable for the consumer to compare window air conditioners by checking the sound power level labels on the unit or in the literature specifications. The noise levels are often given in decibel ratings and the higher the decibel level, the louder the unit will be. The sound pressure increases by a factor of ten for every 10-decibel increase. For example, 60 Decibels is 10 times louder than 50 Decibels and 100 times louder than 40 Decibels. The compressor and the fan are combined in a single unit and mounted in the window air conditioners and this is the source of all the noise in the air conditioner. The other causes of noise could be worn bearings, cabinet rattles, dirty or rusty fan blades, worn rubber mountings and compressor wear. Regular maintenance can reduce the noise to some extent but with the passing of time, there is bound to be an increase in the level of the noise. You should check whether your window air conditioner is vibrating or producing a rattling noise and if so, then it is not a normal situation. The reason for this can be improper installation or loose side panels. If, however, you hear a scraping noise, you should either take the help of an authorized service provider or you can also try to find out the cause and repair it yourself. The following steps can help you in tracking the fault and repairing it: You should tighten the screws holding the front panel onto the unit. You should check carefully the window all round the unit. You should then turn the window air conditioner on and press your hand against the sash. If you find that as you press your hand against the sash, the sound changes in pitch, then you should put some wooden shims in the gap between the window air conditioners frame and the sash. If, however, the pitch of the noise changes when you press your hand on the glass, you should use some insulating cellophane tape between the glass and the frame. You might have to use putty if that does not reduce the noise. If you feel that the sound is originating from within the unit, you should take the unit out of the window and check to see if the fan blades are bent. If so, just bend them back so that they match the others. Portable Air Conditioners Ensure Economy And Convenience With the onset of the damp weather, it becomes difficult to survive without constant central air conditioning but that can prove to be quite expensive. The answer to this problem is a portable air conditioner as it has many advantages. It is easy to shift from one place in the home to another and that makes a portable air conditioner the ideal cooling system solution for your home, office or industrial site. The portable air conditioners are easy and quick to install, as they do not involve any lifting or tearing up of windowsills. Moreover it can be shifted very easily from one place in the home to the other. For taking care of the hot spots in the central air conditioning, the portable air conditioners are far more convenient than window air conditioners. It is also ideal for window shapes, which present problems for installation. There is nothing like portable air conditioners for use as a spot cooler in the home. A portable air conditioner is an excellent choice for saving money as just one unit needs to be purchased and it can be shifted easily to where you need it as it is mounted on castors and some can weigh only about 36 pounds. Moreover, as only one room is cooled at a time instead of the whole house, the total energy consumption is very low as compared to other air conditioning systems. Another advantage of portable air conditioners is the energy efficiency that they provide. The average efficiency is in the 8 to 10 range although some are as high as 15, which is 50 percent better than most older central air conditioners. The small size of the portable air conditioners is very advantageous and as such it can fit in a corner or against a wall. It functions like an effective dehumidifier if you do not vent the warm exhaust air out through a window and its size is also the same as that of a room dehumidifier. In order to reduce humidity and allergies, even the small ones remove 35 pints of moisture per day from the room air. The portable air conditioners also use the heat-exchange principle as the other air conditioners to cool and dehumidify the air. The operating principle is also similar to a window air conditioner as the room air circulates over cold evaporator coils to cool and dehumidify it inside the unit. The room air is exhausted outdoor after flowing over the hot condenser. There is no chance of already-cooled indoor air escaping outside as two ducts are now used. Nowadays, you have electronic controls in most models and you can set the desired room temperature, blower speed, start and stop timer, and operation mode (cool, dehumidify, heat). The portable air conditioners also have hand-held remote control with which you can conveniently change all the settings as per your need. The other features of portable air conditioners include a built-in air cleaner with an optional charcoal filter and oscillating louvers to distribute the cool air throughout the room. You can also switch off the louvers to direct the flow of air towards yourself, if you so desire. About the Author: 相关的主题文章:
