High impact information on Air Conditioning

• The climate sensitivity parameter (gamma, the equilibrium response of global mean surface temperature to doubled CO2) was used to define the control climate [1].
• Two species of amoebae were isolated from the cooling tower of an air-conditioning system and examined for effects of exposure to four cooling tower biocides, a thiocarbamate compound, tributyltin neodecanoate mixed with quaternary ammonium compounds, another quaternary ammonium compound alone, and an isothiazolin derivative [2].
• We conducted 2 episodes of superheat-and-flush based on the published recommendations from the Department of Health, Taiwan; US Centers for Disease Control and Prevention; and American Society of Heating, Refrigerating, and Air-Conditioning Engineers [3].
• The influence of air conditioning, humidity, temperature and other household characteristics on mite allergen concentrations in the northeastern United States [4].
• We report the first study of R-134a (also known as HFC-134a and CF3CFH2) refrigerant leakage from air conditioning (AC) systems of modern vehicles [5].

Biological context of Air Conditioning

• Reflexes that serve to optimize the air-conditioning function of the nose by altering sinus blood flow, or serve to protect the nasal mucosal surface by mucus secretion, vasodilatation, and sneezing, can be initiated by a variety of stimuli, including allergen, cold air, and chemical irritation [6].

Associations of Air Conditioning with chemical compounds

• Alternative forms of air conditioning to evaporative cooling may be useful for control of mite allergen in dry regions [7].
• 1,1,1,2-Tetrafluoroethane (R-134a) is a non-ozone-depleting alternative to dichlorodifluoromethane for use as an air-conditioning refrigerant and as a propellant in anti-asthmatic and other pharmaceutical preparations [8].
• Under 5% O2, intact follicle survival up to day 12 was significantly reduced as compared to the 5% CO2 in air conditioning [9].
• We have developed protocols to deliver 2% d-phenothrin at a dose of 35 g per 100 m3 in various aircraft, and trials undertaken on Boeing 747 and 767 aircraft showed that their air-conditioning systems do not preclude effective disinsection [10].
• Indoor CO2 concentrations often exceeded 1000 microl/l in air-conditioning and ceiling fan classrooms, indicating inadequate ventilation [11].

Gene context of Air Conditioning

• Aeroallergen sensitization in pediatric allergic rhinitis in Singapore: is air-conditioning a factor in the tropics [12]?
• These staff were likely to have worked in areas of the hospital ventilated by the contaminated air conditioning plant, but not necessarily the OPD [13].
• Air conditioning systems may increase the prevalence of SBS-symptoms relative to natural ventilation if not clean [14].
• 4. Simple air-conditioning can reduce the temperature sufficiently for the viability of the embryo to be preserved for up to a week [15].
• The ECLSS Test Program encompasses the Water Recovery Test (WRT), the Integrated Air Revitalization Test (IART), and Life Testing, which permits ECLSS design evaluation [16].
