A heat exchanger 7 in the unit body exchanges heat between the in-drawn outdoor air and air drawn from the chamber by the discharge blower, and a filter 10 in the unit body filters the mixture of in-drawn outdoor air and the air drawn from the chamber by the circulation blower 9. <IMAGE>

Description

SPECIFICATION An air conditioning unit The present invention relates to an air conditioning unit and more particularly to an air conditioning unit which carries out ventilation of the air in a chamber and a cleansing treatment of the air therein.
A conventional air conditioning unit of this kind has a constitution such as that shown in Fig. 1 of the accompanying drawings. An air conditioning machine room 1 is provided within a building and the air sucked by the air conditioning unit from the outside is passed through an air filter unit 2 and a heat exchanger unit 3, and then supplied to the respective chambers through air supply ducts 4.
The contaminated air within the respective chambers is returned to the machine room 1 through air discharge ducts 5, and after it is subjected to the cleansing treatment, its heat is exchanged and it is supplied to the chambers together with air coming from the outside.
However, the conventional air conditioning unit having such an arrangement and operation has various defects as listed below: 1. Since the air conditioning machine room 1 must be provided inside the building, the effectively usable space within the building is decreased; 2. Since air treatment equipment of a large capacity is required, a full-time superintendent is necessary; 3. Spaces for the supply and discharge ducts 4, 5 are necessary; 4. Since the respective chambers are in communication with each other through the ducts 4, 5 prevention of disasters such as a fire is made difficult; and 5. Since the individual operation for the respective chambers is impossible, the operation of equipment of large capacity is made unavoidable even if only one chamber is to be air conditioned, causing uneconomical operation.
It is a principal object of the present invention to provide an air conditioning unit of the kind as described above which can eliminate all of the defects in the conventional unit as listed above.
It is another object of the present invention to provide an air conditioning unit which can be combined with a unitary-type air conditioner or a terminal unit of a central air conditioner.
It is a further object of the present invention to provide an air conditioning unit which does not require a large-size air conditioning machine room or large-size air treatment equipment.
It is a still further object of the present invention to provide an air conditioning unit which can be economically operated.
It is also an object of the present invention to provide an air conditioning unit which requires minimum space for ducts.
It is other object of the present invention to provide an air conditioning unit which is advantageous from the standpoint of disaster prevention because of the elimination of ducts between adjacent chambers.
In accordance with the present invention an air conditioning unit is provided which comprises a body adapted to be installed within a space above the ceiling of a chamber, the body being provided therein with an air suction opening and an air discharge opening from and into the chamber as weil as an air intake connecting means to suck the outdoor air into the chamber and an air discharge connecting means to discharge the air in the chamber to the outside, a blower to suck the air within the chamber through an air suction opening formed in the ceiling of the chamber and to discharge it outside through the air discharge connecting means, an air circulation blower to suck the air within the chamber through another air suction opening formed in the ceiling as well as to suck the outside air through the air intake connecting means and to discharge the air from both sources into the chamber through an air discharge opening formed in the ceiling, a heat exchanger to effect heat exchange between the outdoor air and the air within the chamber, and a filter means adapted to filter the air within the chamber sucked into the unit body by the air circulation blower and the outdoor air sucked by the blower after the outdoor air passes through said heat exchanger.
These and other objects of the present invention will become more readily apparent upon reading the following specification and upon reference to the attached drawings, in which: Fig. 1 is a diagrammatical representation illustrating a general arrangement of a conventional air conditioning unit; and Fig. 2 is a longitudinal sectional side elevation of a principal portion of one embodiment of the present invention.
Referring now to Fig. 2 of the accompanying drawings wherein reference numeral 6 shows a body of an air conditioning unit adapted to be installed with a space A above a ceiling of a chamber 18, the body 6 housing therein a stationary heat exchanger 7, a blower 8 to discharge air within the chamber 18 to the outside, a circulation blower 9 to circulate the air within the chamber 1 8, and an air filter 1 0. 11 shows a ceiling service panel provided with an air suction opening 12 therein, the panel 11 being mounted to the surface B of the ceiling within an opening formed therein, and adapted to be opened and closed, and 1 3 shows a panel exposed to the surface B of the ceiling so as to be integral with the panel 11 and formed with an air discharge opening 14 to discharge the air into the chamber 1 8. 1 5 shows an air discharge connecting means to discharge the air within the chamber 18 and 1 6 shows an outdoor air intake connecting means to suck the outdoor air, both being provided in one of the sides of the body 6, the connecting means 1 5 and 1 6 being in communication with the outdoors through an air discharge duct 1 7a and an air intake duct 1 7b, respectively.
During the operation of an air conditioning unit having the constitution described above, the air within the chamber 18 is sucked by the blower 8 through the air suction opening 12 into the body 6 and discharged to the outdoor through the discharge connecting means 1 5 and the air discharge duct 1 7a after passing through the stationary heat exchanger 7 as indicated by the dot-and-dash line with solid black arrows.On the one hand, the outdoor air is sucked from the outdoors by the air circulation blower 9 through the air intake duct 1 7b from the outdoor air intake connecting means 16, the outdoor air exchanging heat with the air discharged from the chamber 1 8 in the stationary heat exchanger, and after the outdoor air thus recovers the heat from the air within the chamber 1 8 and passes through the air filter 10, it is blown into the chamber 1 8 from the air discharge opening 14. See the dotted line with a hollow white arrow shown in Fig. 2.On the otherhand, the air within the chamber 1 8 is sucked by the air circulation blower 9 from the suction opening 12, and after it is combined with the outdoor air which has been heated in the stationary heat exchanger 7 it also passes through the air filter 10 to be filtered, and it is discharged again into the chamber 18 through the discharge opening 14.
That is, the outdoor air which has recovered heat from a portion of the air within the chamber 1 8 is mixed with a portion of the air within the chamber 1 8 to refresh it, and after the air thus combined has been subjected to the cleansing treatment by the air filter 10, it is supplied to the chamber 1 8.
Therefore, when a number of chambers are to be air conditioned, if the respesctive chambers are provided with separate cooling and heating devices, or if they are each provided with a terminal device of central cooling and heating equipment together with the air conditioning unit in accordance with the present invention as described above, one or more separate chambers which require cooling or heating can be air conditioned by operating the air conditioning units belonging to those chambers.
From the foregoing it will be appreciated that the present invention provides an air conditioning unit in which the ventilation of the air and the recovery of the waste heat of the air within the chamber can be carried out by the heat exchanger and at the same time the air within the chamber can always be kept clean. As a result, the air conditioning unit in accordance with the present invention can be combined with a separate cooling and heating device or a terminal device of central air conditioning equipment without necessitating a large air conditioning machine room or large air treatment equipment such as required for conventional air conditioning equipment, and the requisite maintenance and management therefor are also eliminated. Since the venting duct can be installed within a space above a ceiling, the space necessary for the ducts can be reduced. The ducts conventionally necessitated for conducting adjacent chambers are also not required, minimizing the chances of fires and disaster occurring, and since the individual operation of the air conditioning units in separate chambers is possible, operation is made more economical.
It is to be understood that although a single embodiment of the present invention has been illustrated and described, it is not to be limited thereto except insofar as such limitations are included in the following claims.
