Climate-conditioning fan and coil apparatus

Abstract

An apparatus for conditioning of air has an air inlet and an air outlet. The apparatus includes a heat exchanger, having a major longitudinal axis and having a shell through which an airflow is forced to circulate, and an exchange coil, fitted within the shell, which contains a heat exchange fluid. The heat exchange is simultaneously, parallel and longitudinal to the air transport, along the major heat exchanger's longitudinal axis. A fan, associated with a motor, produces the flow of air to be conditioned. The fan has an air inlet and an air outlet connected to the heat exchanger. At least one silencer is coupled to the entrance or to the exit of air.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This nonprovisional application claims priority under 35 U.S.C. § 119(a) on Patent Application No. PA / a / 2006 / 007633, filed in Mexico on Jun. 30, 2006, the entirety of which is incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to an air conditioning apparatus. More particularly, the present invention relates to an air conditioner of the fan-and-coil type.[0004]The present invention refers to a climate conditioning system having an electric motor associated with a fan. The fan generates an air flow passing through a heat-exchanger element in a co-linear distribution, on the same axis to which modules in the form of filters can be added for handling of particles or bacteria, dust filters, as well as in the form of elements for controlling moisture, among others.[0005]2.

AI Technical Summary

Benefits of technology

[0016]Therefore, an objective of present invention is to provide an air-conditioning apparatus having reduced equipment volume.

[0017]Another objective of present invention is providing air-conditioning equipment, of the “fan-and-coil” type that has reduced noise characteristics.

[0018]Another objective of present invention is to provide an air-conditioning apparatus that has low requirements for its installation and maintenance.

Problems solved by technology

Equipment such as those of the “fan-and-coil” type of the background art have some drawbacks, among others: (a) excessive dimensions, (b) noise, (c) high requirements for installation and maintenance and (d) they need additional and costly components.

Also, the installation of such systems is limited by the ancillaries for mounting, water supply and condensing water collection, and require a system of ducts and grilles to distribute air flow and for the proper operation of the systems.

To this end, several motors are used, working simultaneously, which generate a considerable noise level.

Due to the design in the apparatus of the background art, it was not possible to use silencers, as these silencers would occupy very large dimensions, and the airflow would be considerably decreased.

Equipment according to the background art necessarily requires an installation specialist after being acquired, in order to be able to operate them, because they are not functional without the proper adjustment and manufacture, nor without special fastenings and adapters to additional elements, such as ducts and fittings.

Finally, “fan-and-coil” systems according to the background art, because of their design, have restrictions for using air-purification accessories and for separating particles or bacteria.

Both chambers cause the equipment to be bulky.

Also, the use of several fans acted upon by the same motors involve high power requirements, which translates into a noisy system.

Furthermore, the equipment has the drawback in that it is not possible to add accessories, for example units for air purification or air treatment.

Although it occupies a space smaller than other systems, it also shares other drawbacks of the background art.

The main drawback is that the apparatus provides a low-volume of conditioning.

This means longer time for conditioning a given space.

Also, such apparatus is noisy, because the fan's motor is exposed over the rooms on which it is installed.

Foreseeably, the noise will increase when more than one unit is used, as in the case of wide halls.

Also, it is not possible to add purifier units or other accessories.

Furthermore, it also shares the drawback of high technical requirements for its installation and maintenance.
