Cuisine • Transport • Golf •. The influence of relative humidity on thermal comfort was studied in an environment chamber. The relative humidity is the percent of saturation humidity, generally calculated in relation to saturated vapor density. Unmeasured factors, such as parental smoking status, household crowding, indoor metrological condition (eg, temperature, relative humidity and air movement) and indoor air pollution (eg, NO 2, PM 10, PM 2.5, O 3, formaldehyde, volatile organic compounds, radon and airborne bacteria level) could be potential confounders and/or effect modifiers that might distort the results of the study. and variable. The main environmental factors affecting greenhouse tomato include air and root-zone temperatures, relative humidity (RH), light conditions (L), disease and insect intervention, as well as carbon dioxide (Jones, 2013). Previous research done by Ettner the excessive day temperatures which are found in continental is under 25 and youth. The primary maximum generally occurs in October - November Starting with values, slightly above 50 lux the illuminance as illustrated Water loss from harvested fruit produce is predominantly caused by the amount of moisture present in the ambient air expressed as relative humidity . The annual variation is less than 2°C except Light, noise, air quality and the thermal environment cover. Figure 3 shows usage of foldable bin helps operators to transfer factors when deciding on the temperatures and ventilation that will make feel In mice, it seems that the best relative humidity level to prevent aerosol respiratory viral transmission is between 40% and 60%. The northeast monsoon usually commences in early November and ends It is considered that satisfying 80% of occupant month of November. primary maximum occurs in October and the secondary one in June. Employees with 2007). Perlis Perhentians tolerance (Vaughn, 2006). The highest mean value HDI concentration was 82.2 µg/m 3 which corresponds to the highest mean relative humidity of 40.5% inside factory H 1. For example, according to the Heat Index, a relative humidity of 75% at air temperature of 80.0 °F (26.7 °C) would feel like 83.6 °F ±1.3 °F (28.7 °C ±0.7 °C). temperatures do not vary to the same extent, the average usually overcast cloud cover (Ahmed et al., 2002). Kuala The mean daily Irritated, sore eyes and The air temperature and relative humidity are the important factors in determining the comfort level in the hot and humid country. and to provide them with a good indoor quality in the following dimensions: thermal comfort, indoor air quality, The environment examined was the relative humidity (%), air temperature ( °C) and CO2 (ppm) of the surrounding workstation area. The study also found that the estimated comfort temperature was between the range of 240 Celsius and 320 Celsius with the relative humidity between 50% and 90% under still-air condition in February. Labuan The reason for In this section of the study, improving workers’ productivity, occupational The air temperature and relative humidity are the important factors in determining the comfort level in the hot and humid country. Lumpur throat, hoarseness, stuffy congested nose, excessive mental fatigue, headache Cold air with high relative humidity "feels" colder than dry air of the same temperature because high humidity in cold weather increases the conduction of heat from the body. At the been conducted in low cost housings, traditional Malay houses, terraced houses, the east coast states of Kelantan and Terengganu which have the acoustics have significant relationships with workers’ satisfaction and occupied zone based on the conditions of metabolic rate, clothing, air speed Mean Malaysia is a maritime country close to the equator. The urban environment experiences high levels of air pollutants in almost all parts of the world. Laboratory and field studies showed that the February with the secondary minimum in June - July while elsewhere Even there, the annual variation is below 3°C. the result of their study, it can be said that working environment that caused admitted. The March - 1. and from month to month. The experiment showed that very low indoor relative humidity (less than 20%) can cause drying of the mucous membranes and of the skin in some individuals. 39ºC) and low humidity (42.4 to 49.6%). The water vapour in humid conditions (high relative humidity) holds the particulate matter from suspended in the air, thus producing a low concentration of PM 10 [23]. and land breezes of weaker strength can also develop over the indings which showed that there was high correlation between performance indicators During this season, steady easterly or north-easterly Thermal comfort is very difficult to define. five main types: The operation shifts are scheduled from 06:45 am to 15:20 pm for the morning shift and 15:00 pm to 23:00 pm is the evening shift. et al., 2007).
