Showing papers on "Thermal comfort published in 1979"
TL;DR: In this paper, the relative sultriness of warm-humid and hot-arid summer climates is assessed using the amount of clothing needed to achieve thermal comfort and the reduction in the skin's resistance needed to obtain thermal equilibrium.
Abstract: Using as bases the amount of clothing needed to achieve thermal comfort and the reduction in the skin's resistance needed to obtain thermal equilibrium, the relative sultriness of warm-humid and hot-arid summer climates is assessed. Conditions of equal sultriness are referred to a vapor pressure of 1.6 kPa in order to prepare a table of apparent temperature corresponding to summer temperatures and humidities.

TL;DR: In this article, a series of laboratory tests involving almost 3000 people were conducted to determine the factors that contribute to the thermal comfort of automobile passenger while using air conditioning under summer heat loads.
Abstract: From 1973 to 1977 a series of laboratory tests involving almost 3000 people were conducted to determine the factors that contribute to the thermal comfort of automobile passenger while using air conditioning under summer heat loads. Four studies will be reviewed.

TL;DR: The PASOLE/SUNSPOT, a thermal network code for direct gain enclosures, has been developed and validated for a quantitative comparison of thermal comfort within the two generic types of buildings as mentioned in this paper.
Abstract: Until recently only the thermal storage wall passive solar heating system had been characterized by thermal network calculators using hour-by-hour historical weather data. The greater popularity and market acceptability of direct gain systems has led to a lively, but inconclusive debate concerning the relative effectiveness of the two configurations. The recent development and validation of PASOLE/SUNSPOT, a thermal network code for direct gain enclosures, has provided the tool necessary for a quantitative comparison. The results of performance analysis calculations for both Trombe wall and direct gain systems in Albuquerque, New Mexico, and Madison, Wisconsin, are reported. The comparative analysis includes parametric variation of fundamental design parameters including building load, glazing area, total mass, mass thickness, number of glazings, night insulation value and allowable temperature swing. Thermal comfort within the two generic types of buildings is considered as well as energy efficient performance.

TL;DR: In this article, Fanger's equation for Pre-dicted Mean Vote does predict comfort in a tractor cab for summer conditons, and a person's idea of comfort does not change significantly after the first half hour in the tractor cab.
Abstract: THERMAL comfort predicted by Fanger's equation for 16 tractor cab occupants is presented and dis-cussed. Results show that Fanger's equation for Pre-dicted Mean Vote does predict comfort in a tractor cab for summer conditons. Also, a person's idea of comfort does not change significantly after the first half hour in the tractor cab. Finally, cab temperature alone is not an adequate indicator of comfort.

TL;DR: In this paper, the authors present a computing process that permits prognoses of the air-flow velocities downstream from the fresh air outlets, and verify compliance with the air flow requirements.
Abstract: Passenger cars sold in moderate climatic zones frequently come without factory-installed air conditioning. Therefore, the temperatures in the vehicle occupant compartment may rise above the thermal comfort range during hot summer months. In order to provide for a maximum of thermal comfort under those circumstances, occupant compartment ventilation should satisfy certain clearly defined requirements. The paper submits the physiological rationale and a concrete description of these requirements. The so-called isotach method was developed to permit a quantitative determination of the vehicle occupant cell air flow and to verify compliance with the air flow requirements. While the application of the isotach method to given vehicles does not pose any problems, there are frequent requests for air-flow data projections during the first stages of new vehicle development. The paper presents a computing process that permits prognoses of the air-flow velocities downstream from the fresh air outlets.

TL;DR: In this article, a thermal comfort model was developed to relate skin surface temperature to ambient air temperature and windspeed, and it was shown that relatively low wind assaults on clothing appreciably reduce the air boundary layer effective thermal resistance and further equal increases in wind speed have decreasingly less effect in reducing the thermal resistance.

TL;DR: In this paper, the Fanger thermal comfort equation is linearized and used to develop a procedure for assessing thermal comfort levels in passive solar heated buildings, and a new thermal index called the equivalent uniform temperature is introduced.
Abstract: The Fanger thermal comfort equation is linearized and used to develop a procedure for assessing thermal comfort levels in passive solar heated buildings. In order to relate comfort levels in non-uniform environments to uniform conditions, a new thermal index called the “equivalent uniform temperature” is introduced.
