Six Holstein cows (averaging 475 kg body weight, 2.3 parities and 96 d in lactation) fitted with catheters in the hepatic portal vein, mesenteric vein and intercostalis posterior artery were exposed to treatments of thermal comfort environments with libitum or restricted (75% of ad libitum) DM intake and a thermal stress environment with ad libitum intake in two balanced 3 x 3 latin squares to ...
Sensations evoked by thermal stimulation (temperature-related sensations) can be divided into two categories, "temperature sensation" and "thermal comfort." Although several studies have investigated regional differences in temperature sensation, less is known about the sensitivity differences in thermal comfort for the various body regions. In the present study, we examined regional difference...
Partial- and whole-body thermal sensation and comfort, Part II: Non-uniform environmental conditions
Subjects were exposed to sequences of partial-body cooling and warming over a period of three hours. Skin temperatures, core temperature, thermal sensation, and comfort responses were collected for nineteen local body parts, and for the whole body. This paper relates local thermal sensations and comfort to skin and core temperatures, and examines how the thermal sensation and comfort perceived ...
In this paper, a new technique is being proposed to estimate the PMV by using an array of sensors for the automatic control of thermal sensation scale of the air conditioning system. The predicted mean vote (PMV) is a well recognized thermal comfort index and is used for measuring comfort level inside the conditioned space. It is a mathematical function dependent on air temperature, relative hu...
Existing thermal comfort field studies are mainly focused on the relationship between the indoor physical environment and the thermal comfort. In numerous chamber experiments, physiological parameters were adopted to assess thermal comfort, but the experiments' conclusions may not represent a realistic thermal environment due to the highly controlled thermal environment and few occupants. This ...
despite the similar performance of bazaar1 in different cities of iran, there are some the skeletal differences between markets in different climates. the bazaar roof protects customers against natural events in any climate. the ceiling height and the sitting down of the bazaar`s floor are determined based on the need for air circulation and movement in various climates. hence, combination of a...
accumulation of unmanaged industrial solid waste, especially in developing countries has resulted in an increased environmental concern. in view of utilization of industrial solid waste the recycled paper mill waste (rpmw) – cement composite bricks were designed and developed. in order to investigate the environmental performance of sustainable construction materials two small scale model house...
BACKGROUND Fanger's PMV equation is the result of the combined quantitative effects of the air temperature, mean radiant temperature, relative air velocity, humidity, activity level and clothing insulation. METHODS This paper contains a comparison of suit dresses and summer clothes in terms of thermal comfort, Fanger's PMV equation. Studies were processed in the winter for an office, which lo...
ABSRTACT: Design strategies for open spaces need detailed information about the thermal comfort conditions. The actual use of open spaces is analysed depending on the microclimatic conditions and activities. With measurements, observations and calculations with a thermal comfort model the results could be used for a open place design. The results are demonstrated at two open spaces in Kassel /G...
Human thermal modulations are becoming a popular subject when concepts such as, safety and comfort are indispensables in workplaces design. The computational fluid dynamic software have been used and they have been assuming a greater impact in this field due to their higher accuracy. Also, CFD studies can provide detailed information about thermal comfort variables near a human computational ma...
