DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to a system which, in order to be able to condition the air in a number of rooms, comprises a heating/cooling unit, distribution pipes and discharge units.
In some prior art building air conditioning systems, a centrally-located heating/cooling unit is employed to provide a large number of rooms with cool, conditioned air. Use of such prior art systems causes the conditioned air supplied to all of the rooms to be thermodynamically uniform, i.e. the air supplied to all of the rooms has the same temperature and humidity.
The situation inside a building of the rooms to be air-conditioned (i.e. north or south exposure) and the use for which each room is intended (number of persons present, whether or not heat-emitting devices are being operated inside the room, etc.) determine the optimal temperature and humidity levels for the conditioned air that is to be supplied to each individual room.
SUMMARY OF THE INVENTION
The object of the present invention, therefore, is the development of an air conditioning system that allows for maximum adaptability to the particular temperature and humidity levels of the air present in each room. The design of the proposed system must, besides permitting functional adaptability, lend itself both to inexpensive production methods and ease of servicing.
It is proposed that the above objects be satisfied by an arrangement of a prior art air conditioning system whose construction is modular, whose vertical height, by not surpassing 22 cm, permits installation in a suspended ceiling, and the configuration of whose discharge units permits regulation of the circulation of conditioned air in accordance with conditions prevailing in each of the rooms to be air conditioned. The proposed air conditioning system embraces the following distinguishing features that are required to provide a high degree of operational flexibility: the modular construction of the proposed air conditioning system both permits reduction of production costs to a level at which a complete heating/cooling unit can be installed in each room at a cost comparable to that of the installation of conventional central systems, and permits regulation of the thermodynamic characteristics of the supplied air to the particular environmental characteristics of each room.
The arrangement of the entire system in a suspended ceiling obviates its taking up otherwise useful space. In addition, the spatial proximity of the heating/cooling unit to the discharge units permits the use of much shorter distribution pipes.
The modular arrangement of the proposed system moreover permits any number of combinations of its discrete components. This feature gains strength from its combination with the shape of the system, and permits installation in a suspended ceiling. The proposed component configuration permits ready access to individual components of the air conditioning system, an advantage that implies that the proposed system can easily be modified for use in a number of different roles. By way of example, if the use of any given room is changed (e.g. furnished with heat-emitting equipment) or if the sectioning of a given enclosed area is changed (e.g. by shifting the positions of moveable partitions in a open-plan office), the heating/cooling unit can be easily replaced by a unit having different performance characteristics. The modular construction, which lends itself well to long and profitable production runs, moreover permits relatively low cost production of the proposed air conditioning system, which allows the system to be fully competitive with conventional central air conditioning systems.
The configuration of the discharge units, by permitting the flow of air to be individually regulated by each of such units, allows each of the several areas of any given room to be fed with conditioned air in accordance with different conditions prevailing in each of such areas.
In order for each discharge unit to be able to optimally modify the flow of air in accordance with the i
