Effects of temperature and humidification in the office environment

In this paper, the links between temperature and Sick Building Syndrome symptoms on the one hand and temperature and workers'perceptions of air dryness in environments with and without humidification on the other hand are evaluated .The average intensity of symptoms and perceptions of dry air relative to room temperature in humidified and non-humidified conditions are studied. The results are presented then analysed .

Ground heat exchangers Erd-Luft-Wärmetauscher

Describes the principle of ground heat exchangers for outside fresh air, giving indications about their design rules and their energy performance, as well as recommendations for their hygienic operation.

Energy savings potentials in air conditioning of industrial buildings Einsparpotentiale bei des Klimatisierung von Industriehallen

Using results from dynamic simulations, the article compares the energy consumption for the air conditioning of an industrial building with mixing and displacement ventilation.

Efficient air conditioning of swimming pools buildings Effiziente Klimatizierung von Schwimmhallen

The article discusses the design of the system with heat recovery to be used for the ventilation/air conditioning of a swimming pool building, in which air reaches high temperatures and humidities. The systems described and analysed use heat recovery through air to air heat exchanger or heat recovery through heat exchanger and heat pump.

Optimal selection and position of swirl air diffusers Dralldurchlässe optimal dimensionieren und anordnen

The author points out the importance of a good selection of the dimensions of swirl air diffusers, using data provided by the manufacturers. It also gives information about the method for deciding of their number and position in the room.

The uncertainty associated with thermal comfort

The purpose of the current study is to compare experimental thermal comfort results with those predicted by the Fanger model. In making this comparison, the uncertainty of the data will be considered along with the uncertainty of the Fanger model predictions based on the uncertainty of the model input parameters. A primary outcome of the study will be a better understanding of the uncertainty associated with thermal comfort predictions. A qualitative comparison illustrates that the Fanger model can predict the experimental results for many of the cases.

A field study of the thermal environment in residential buildings in Harbin

This paper presents the main findings of Project HIT.2000.25 supported by the Scientific Research Foundation of Harbin Institute of Technology, a field study of indoor climates and occupant comfort in 66 residential buildings in Harbin, located in northeastern China.

Literature review of the advances in thermal comfort modeling

Fountain and Huizenga (1995) conducted a comprehensive literature review of thermal comfort models. Significant advances in thermal comfort modeling have been achieved since that review. The present paper summarizes the advances in thermal comfort modeling for both building and vehicle HVAC applications that have occurred since Fountain and Huizengas literature review. This paper is intended to describe the potential use of these models and to demonstrate their suitability for predicting comfort during complex transient and non-uniform environmental conditions.

Investigation of human thermal comfort under highly transient conditions for automative applications Part 2 : thermal sensation modeling

This paper focuses on the mathematical modeling of dynamic human thermal comfort under highly transient conditions for automotive applications. A combined physiological and psychological modeling approach was taken. First, the transient environmental and human activity data, plus the
clothing insulation data, were used as inputs to a human thermal model to determine the physiological responses for the vehicle thermal environmental conditions. Secondly, a series

Investigation of human thermal comfort under highly transient conditions for automative applications Part 1 : experimental design and human subject testing implementation

This paper focuses on the experimental research of developing models to effectively predict the dynamic whole body and local thermal comfort under highly transient conditions. Two approaches were taken subsequently. The first step was to collect environmental data with a testing vehicle under transient and non-uniform conditions. An environmental chamber was used to simulate 16 typical winter and summer conditions, which fully covered the range of thermal conditions necessary
