Less noise emit a ventilation unit, the blades of the impeller which are calculated aerodynamic shape, they set in motion a special low-noise motors. Another source of noise is the fan, spreading the moisture from the drain pan to the heat exchanger for the purpose of more intensive diversion of heat from the refrigerant. To eliminate this source of noise will be enough to unscrew the cap from the drain valve, then put on the plastic tube that carries the condensate to the street — the accumulation of moisture in the pan will stop and the noise will disappear.
To check window air conditioner on the level of noise is necessary in the trading room, to pay for the product — you need to be at full cooling capacity. To test for noise window air conditioner should be placed indoors, which cannot be penetrated by strange noises. Window air conditioners lower price segment are equipped with electromechanical controls, the more expensive models are equipped with pressure and touch sensitive buttons, equipped with remote control, indicators on specific characteristics are displayed on the LCD display. When choosing ways to control a window air conditioner best come from the location of the appliance: if it will be installed in the lower part of the window opening, press a key on the control panel is easily achievable; if the air conditioner is set in the upper part of the window, it is possible to get the switches is possible only with chair, in this case, the most optimal model selection with the remote control. Note — if the specifications of this model of window air conditioner indicates the maximum permitted area of the premises served, for example, 150 square feet, with 170 th square feet, it fail, it will need a more powerful device. In the endThe hole is designed to install window air conditioner, you want to run on 2/5 inch more than required sizes of candy bar — the gap left after installation, fill the rubber gasket. When installed in the upper part of the window frame it is important to observe the distance between the ceiling and the unit is not less than 8 inches, because at smaller distances it will pump generates the same cold air that will affect the quality of the work, because the evaporator is covered with ice. The minimum distance from the outside (street) side of the monoblock from any object in front of it — 20 inches. How to install a Window Air Conditioner
A Packaged Terminal Air Conditioner
A packaged terminal air conditioner (often abbreviated PTAC) is a type of self-contained heating and air conditioning system commonly found in hotels and apartment buildings. Many are designed to go through a wall, having vents and heat sinks both inside and outside. Different standard dimensions are found in the market including 42×16 inches (1067 x 406 mm), 36x15 inches, and 40x15 inches. Although PTACs are used mostly to heat or cool a single living space using only electricity (with resistive and/or heat pump heating), you can find cooling only PTACs with external heating through a hydronic heating coil or natural gas heating. Typical PTAC heating and cooling capacity values range from 2 kilowatts (7000 BTU/Hr) to 5.5 kilowatts (19000 BTU/Hr) nominal.
