A/C Chilling Ventilation
Domestically, most air-conditioning systems are used in Summer during the evening. It is a matter of fact that this seasons may be unbearable due to the southern winds and high levels of humidity. The easiest enhancement in such a situation is to operate the air conditioning system at a relatively low temperature for thirty minutes and then switch the air-conditioning unit to ventilation mode. This will yield a very similar result to that of a system operating continuously in refrigeration mode. Such a procedure be carried out manually or by the use of special functions designed by the manufacturer of the unit. Ideally, the IEE or IEEE should endorse such a function to domestic air conditioning systems.
The operation of any kind of refrigerator relies on the use of radiators in aim of dissipating heat or absorbing heat in Summer and Winter correspondingly. In the warmer seasons its aim is to lower the ambient temperature. This occurs by releasing the heat through its radiators, hence any form of external heat source such as a stove or cooker can affect the efficiency of the refrigerator's motor. By keeping it away from heat sources such as cookers, stoves or exposure to sunlight, the efficiency and efficacy can be alleviated. This improvement is usually noticed by the less frequent start-ups of the compressor.
Dust accumulates on radiators' surface from time to time making it more difficult to release heat from the radiator (chilling). In such a case the electrical drive inside the compressor will operate for longer periods of time. As a safety measure the power should be voided form the unit before cleaning it. The compressor requires 15 minutes cool down before being switched on again otherwise its wear and tear is increased.
Besides from isolating the unit from external heat sources, it is very important that a refrigerator operates in low levels of humidity. In winter the water molecules will absorb the radiators' heat themselves. Similarly in Summer the vapour will conceal an additional heat source (absorb the cold). Water has the highest specific heat capacity, thus it will obstruct any change in temperature. Correct dehumidification will aid at maintaining the best efficiency of any kind of refrigeration units. In the case of refrigerators, it is very inconvenient to locate them near a door or any kind of aperture. The molecules would oppose any change in temperature.
