As shown in
There may be more than one fan 40 mounted in the housing 21. If more than one fan 40 is utilized in the housing 40, it may be desirable to have adjacent fans to operate in the opposite direction.
The fan module 20 may include a small heating unit (not shown) to operate in conjunction with the fan 40. When a small heating unit is used, the fan 40 can operate to distribute the warmed air toward the person using the monitor 10. During the summer months, the heating unit would not be activated. Thus, the fan 40 would operate to have a cooling effect on a user. Alternatively, instead of utilizing a heating unit 60 the fan 40 and housing 21 may be configured to take advantage of the heat generated by the monitor 10 and distribute the heat in the direction of a user. The purpose of the fan 40 is to provide a cooling effect in a warm environment and a heating effect in a cold environment to optimize the comfort level of the user. The fan module 20 may be rotated 32 about the axis 31 to direct air from the fan 40 toward user of the monitor 10. The fan module 20 may be configured such that the fans 40 are positioned in proximity to a fan inlet 42. The fan inlet 42 could be positioned near an outlet 11 of the monitor 10 from which the heat generated within the monitor 10 is dissipated from the monitor 10 and distributed toward a user The fan module 20 can be positioned to direct air from the fan 40 toward a user.
The fan 40 may be powered by electrical energy. The fan module 20 may incorporate a power cord 44 to supply energy to the fan module 20. The monitor typically has an AC power cord 46 The power cord 44 could be plugged directly into the power source, the monitor, or into a USB plug 48 in the monitor 10.
The fan module 20 may also incorporate a MERV or MEPA filter in conjunction with the fan. The filter could be positioned near the vent 50. A MERV filter refers to a minimum efficiency report valve to provide air-cleaning properties of a filter. MERV filters rated between 1 to 4 control contaminates like pollen, dust mites, dust, fibers, etc. MERV filters rated between 5 to 8 control contaminates such as mold, spores, hair dander, pudding mix etc. HEPA filter is a type of mechanical air filter that forces air through a fire mesh that traps harmful particles, such as, pollen, pet dander, dust mites and smoke. The MERV and HEPA filters improve the environment of the user.
The fan module 20 may include an LED light source or a UV light source. U.S. Pat. No. 10,316,141 is directed to a built-in air flow mechanism and UV air purifying device built into a ceiling tile. This disclosure incorporates by reference the entirety of U.S. Pat. No. 10,316,141. Particular reference to specific examples, from U.S. Pat. No. 10,316,141, can be seen in FIGS. 6, 7 and 8 as well as Columns 13, Lines 17 through Column 16 line 47.
Embodiments of the invention further include the functionality of irradiating germs out of the air using UV light fixture positioned in the fan module. Such embodiments provide the advantage of not only circulating air in an environment, but also killing viral, bacterial, and fungal species which may be living in the environment's air. While the UV light degrades organic materials, inorganic materials (including metals or glass) are not affected by UV light. Therefore, UV light is effective for reducing organic matter which may be airborne in the air. Reducing airborne contaminants may be important in any environment, but especially in hospitals or schools, which may be particularly susceptible to disease. Regardless of the environment, disinfecting the air of contaminants is helpful to reduce the spread of disease.
It is preferable to reduce or eliminate contact with UV lighting because UV light can be harmful to humans and/or animals (particularly over prolonged durations). Embodiments of the invention therefore provide the advantage of positioning a UV light source in the fan module, where the UV rays may be contained in the fan module. For example.
The UVC light source 170 emits light in a range that irradiates organic matter residing in air as air flows from the kill chamber 123 to the vent 124. A person of skill in the art would recognize that UV light sources include a power source and may optionally include an on/off controller (not shown). The UV light source 170 may be activated by an on/off button, or it may be controlled by the remote-control feature described further herein. In such an embodiment, a remote control may include the ability to activate or de-activate a UV tight source 170.
In some embodiments, light source(s) 170 may emit UVC light, which has a wavelength of approximately 200 to 280 nanometers. A person of skill in the art would recognize the UVC light is optimal for irradiating airborne contaminants (such as viruses, superbugs, mold, and the like) in most environments. In embodiments of the invention, the upper baffle 122 and/or the lower baffle 126 may be made of, or coated with, a UV-reflective material. A person of skill in the art would recognize that a UV-reflective material could include a metal, such as stainless steel, or a specialty coating. Lining the airway with a reflective material and/or reflective coating provides the advantage of creating a “kill chamber,” or “kill zone” inside the airways 123 where UV rays may bounce to increase their exposure to air passing through the kill chamber 123 and by extension, increase the irradiation of organic matter contained in the air.
Furthermore, some embodiments of the inventions may include a UV-screen in the form of flange or protective shield 125 which may be positioned in the vent 124 or kill chamber 123 to shield UV rays from exiting the airways and entering an environment (such as a room or commercial space). In this way, including protective shield 125 in the vent 124 or kill chamber 123 prevents the UVC light rays from exiting the kill chamber 123. Although
A test of a unit utilizing the UV-C light source 170 was conducted. The study was conducted to verify the unit's microbial reduction efficacy of aerosolized contaminants. The unit was mounted on the ceiling in a sealed 11′ 10″×11′ 10″×8′1″ (1125 cu.ft) controlled environment room. The unit's fan and UV lamps were powered on and allowed to warm up over the course of 2-hours as part of conditioning. Aliquots of the microorganisms were added to a pre-sterilized nebulizer reservoir. The testing room was sealed; all equipment activation was performed remotely. The nebulizer was powered to aerosolize the microbial suspension. Following 5 minutes, the UV-C right source and fans were powered on. Samples of the air were collected immediately after unit activation using Bio-aerosol air impinger (Biosampler, SKC, Inc.). The air sample were collected over the course of three minutes. Air samples were collected again following 1 and 2-hours following start. The system was deactivated, and the room was exhausted for 25 minutes before entry for sample retrieval and subsequent analysis. The study was repeated as described with only the fans running and then again with the unit completely powered off. All collected samples were analyzed in triplicate at the minimum as per standard lab operating procedures. Analysis was conducted as per laboratory—s accredited ISO17025:2005 methodology: bacteria were analyzed as per SM 9215 (APHA 2012) and MS-2 as per EPA 1602. Analysis was conducted using calibrated and/or validated Instruments to traceable standards (NIST). All QC was within method acceptance limit. No general environmental conditions are specified in the standard or have been identified that could affect the test results or measurements.
The test results demonstrated the following: The test resulted in a finding that 99.6% of K. pneumoniae was eliminated from the air after 1-hour of operation, and 99.998% of K. pneumoniae was eliminated from the air after 2-hours of operation. There was a 30% reduction of K. pneumoniae from the air after 1-hour of operation when the UV light source was not activated. The tests further found that 98.4% of the MSZ virus was eliminated from the air after 1-hour of operation and 99.6% of the MSZ virus was eliminated after 2-hours of operation There was a 27.2% reduction of MSZ virus from the air after 1-hour of operation when the UV light source was not activated.
