It consists of a heat pump to provide a cold zone where moisture condensation and a warm area to recover the temperature. It works by passing a current of air through the evaporator (cold zone), which is at a temperature below the dew point, causing the humidity to condense and drip into a tank or a drain. After being dried and cooled air passes through the condenser (hot zone), which retrieves the ambient temperature and further decreases its relative humidity. Sometimes you can make ice in the cold. In some devices, when it detects that the temperature in the cold fall below 0 degrees, for the heat pump, but the fan continues to move until the ice melts. It might seem that the process does not alter the temperature but affected because all the electrical power used by the refrigeration equipment (compressor + fan) plus latent heat of vaporization of all the condensed water has to be dissipated into the environment. The maytag dehumidifier is used to reduce and control humidity, especially in the summer. Not for floors or other items dry. It is also used in industrial processes with high power devices. In this post I refer to what seems a serious design error for a device that can be found in any home. I speak of a maytag dehumidifier which its function is to reduce wind chill so that the temperature increases and thus is very beneficial for people suffering from asthma, allergy and nasal irritation as is the case of some members of my family. The problem is exposed in the highlight video, and that the device is simply too noisy in both its operative and launch automatically to detect the humidity is not ideal in the room, since it is an apparatus for use in confined spaces wherever needed. When you start automatically emits a very loud high-pitched beep with which awakens even the deepest sleep, and more trouble the device has no function button or we can choose in which disable the beep on or off the automatic mode and that works then all night. This is a clear example of failure of border enforcement, the section of convenience, effectiveness and high failure also in the restrictions. One possible solution would be to have a remote for that device on which to select different functions or turn on or off thus customizing the wind chill. While this remote control has the disadvantage of all remote control is the loss and complication after this or just an object but on our bedside table, for example, so crowded with different types of control for all possible devices have today in our bedrooms or living rooms. Finally I think the best solution would be a device like the one shown in the picture below, which besides being much quieter in operation even when the machine activated to signal activation illuminates your screen just made that we would no sleep disorder because its luminosity is very low. . . .
