What are the characteristics that differentiate air conditioner from air conditioning?
The air conditioner and air conditioning are both devices that are used to change the temperature of a closed environment, but they are not the same thing: the air conditioner is used to cool the 'air, while the air conditioner is a device that is capable, not only of cool' air, but also to dehumidify it, filter it and heat it, with the possibility to set the temperature and l 'moisture.
The air conditioner is a device used to cool the 'air. It thanks to a fan circulates the air cooled by gas, which blends with that already present in the surrounding environment, so as to cool it, it is possible to adjust the fan speed, but not the air temperature. The cold air is delivered in a continuous manner. There are two main types of air conditioners:
- Conditioners "cold" systems are aimed at cooling only of 'air, and therefore can only be used when it's hot.
- Conditioners "hot": provide the possibility of heating of 'air and therefore are also usable d' winter to increase the internal temperature of the premises. Also to produce hot air, in 'plant has a' reverse cycle of cold, which is subtracted for all hot air 'exterior which is disposed inside. With this type of air conditioners, there is the risk that during the winter, the heat pump is not able to operate in a continuous manner, especially when the temperature is very low, in fact, the device should take heat from cold air already.
Both of the two types of air conditioner can operate according to two different technologies and their energy consumption:
- Conditioners "on-off" are the least expensive but consume more energy. Already since powering the appliance reaches the maximum power, which is often higher than that which actually serves to cool the environment, therefore, is not fully used.
- Conditioners "inverter": they are more expensive, but allow significant energy savings. These devices are of type "modulating", in fact the power of the air conditioner varies in function of the cooling obtained and therefore develops in a gradual manner. In this way the air conditioner comes to use little electricity after 2-3 hours after and is only used than is actually required, as they vary the emission of the hot and cold air according to the actual needs of the environment.
The air conditioner is a device which can cool or heat the air but also dehumidify and filter: allows you to adjust the temperature by setting the degrees Celsius, and the humidity to suit your needs. Once you have reached the desired temperature, the air conditioner will automatically lock, turn on again as soon as the temperature is raised or lowered again, moving away from what is desired, set initially. This allows for constant values of temperature and relative humidity, with low power consumption. The air conditioner works on the basis of the reverse cycle chiller. The machine absorbs heat from the cold reservoir and work from the outside to dump heat in the hot tank. Purpose of the refrigeration cycle is to transfer heat from a source to a lower temperature to another at a temperature higher: for the second law of thermodynamics, this result is only possible if there exists an effect compensator. Therefore, the air conditioner operates as a real freezer or refrigerator, as it is able to transfer a certain amount of heat from the interior to be cooled, the external environment. The air conditioner can be installed in every room, at home, in offices, in means of transport (car, camper, etc.)..
