DUALJET NEW FAN COIL UNIT WITH CONTROLLED OUTLET Floor installation Environmental comfort and dynamic terminals.

Environmental comfort and dynamic terminals. The term environmental comfort means the particular condition of well-being determined by temperature, humidity of air, sound and lighting levels found within an environment in relation to the subjective perception of each person. Studies of environmental comfort show that optimal well-being is achieved depending on the relationship established between the subjective variables and the environmental variables. Subjective variables Relative to the individual it is the activity undertaken within the environment. Environmental variables - Air temperature...

The problem. One of the main causes of discomfort is the perception of a non-homogenous vertical distribution of temperature in the space. This is the situation that can happen in heating, during the winter season. The vertical intake of warm air can lead to effects of stratification: the warm air, being less dense, tends to occupy the higher part of the room leaving the lower part to the colder air with a consequent reduction of perceived comfort. In recent years there is the widespread belief that the best way to overcome this stratification of air is obtained by using under floor radiant installations...

Description of the tests. Aermec has subjected the new DUALJET fan coil unit to rigorous tests, both inside a Real Room, to verify the distribution of heat, as well as inside a special anechoic chamber, to verify the acoustical performance. The expected results were amply confirmed by the tests undertaken. Results With the new DUALJET fan coil unit (with downward warm air discharge) the thermal gradient is highly contained in the whole heating period and it can be noted how a steady state condition is achieved in a gradual manner with the complete absence of annoying temperature fluctuations....

The advantages of DUALJET. The substantial absence of the stratification phenomenon reflects on the level of comfort perceived in the space in normal conditions and avoids even the unpleasant sensation, in the presence of strong thermal gradients, when getting up from seated as there is a significant homogeneity of space temperature. Besides this the new system maintains, with respect to under floor radiant systems, all the undoubted advantages of the fan coil unit: - short system start-up time - precision in setting up and in control - single system for summer conditioning and for environmental...
