ABSTRACT:
ORIGIN OF THE INVENTION
The invention described herein was made in the performance of official duties by an employee of the Department of the Navy and may be manufactured, used, licensed by or for the Government for any governmental purpose without the payment of any royalty thereon.
BACKGROUND OF THE INVENTION
1.0 Field of the Invention
The present invention relates to an air-conditioning system and, more particularly, to an air-conditioning system that is portable and modular so that it may be capable of being carried and moved about and can be arranged into many configurations so as to meet various thermal, filtration and power requirements.
2.0 Description of the Prior Art
A person's ability to accurately and repeatedly perform assigned tasks is dependent, in part, on the temperature of the environment in which the person is placed. If the environment can be maintained at a relatively constant temperature at a relatively low humidity, such as achievable by air-conditioning systems, the ability of a person to successfully perform the tasks increases.
Air-conditioning systems that clean air and control the humidity and temperature of the air are well known and find plentiful usage in stationary buildings, as well as moving vehicles. However, once the air-conditioning system is situated at a location in the building or moving vehicle, it commonly remains there for its operational life.
In addition to stationary air-conditioning systems, man-mounted, portable air-conditioning systems find usage in domestic and commercial buildings, but once again, once the air-conditioning system is situated at a location it commonly remains at that location for the remainder of its operational life. It is desired to provide an air-conditioning system that is easily capable of being carried and moved about so that it may be easily relocated so as to satisfy various thermal requirements in various buildings.
Air-conditioning systems, both stationary and portable types, are commonly removed and replaced with other air-conditioning systems so as to meet various thermal, filtration and power requirements as the need thereof arises within a building. It is desired that an air-conditioning system be constructed with module units so as to provide flexibility to satisfy various thermal, filtration and power requirements.
OBJECTS OF THE INVENTION
It is a primary object of the present invention to provide an air-conditioning system having modular construction so that it may be configured to provide flexibility in satisfying various thermal, filtration and power requirements as the need thereof arises.
It is a further object of the present invention to provide an air-conditioning system that is portable and man-mounted so that it is capable of being carried and moved about in order to satisfy various thermal, filtration and power requirements as the need thereof arises.
It is a further object of the present invention to provide for a modular portable air-conditioning system that inefficient in its operation while at the same time is modular so as to provide add-on capabilities for the air-conditioning systems.
SUMMARY OF THE INVENTION
The present invention is directed to an air-conditioning system that is portable and man-mounted as well as having a modular construction.
In one embodiment of the present invention, an air-conditioning modular system comprises a heat exchanger, and means for transferring water from a reservoir to a heat adsorbing material. The heat exchanger comprises an upper compartment having entrance and exit ducts and containing a water adsorbing material. The heat exchanger further comprises a lower compartment having entrance and exit ducts and containing water and also housing heat-exchanging fins. The air-conditioning module utilizes tubes for interconnecting the upper and lower compartments of the heat exchanger. The pressures of the upper and lower compartments are maintained so as to reduce the boiling point of water therein to be near room temperature.
