The purpose of this study was to examine the effects of skin cooling and heating on the heart rate (HR) control by the arterial baroreflex in humans. The subjects were 15 healthy men who underwent whole body thermal stress (esophageal temperatures, approximately 36.8 and approximately 37.0 degrees C; mean skin temperatures, approximately 26.4 and approximately 37.7 degrees C, in skin cooling an...

WEATHERS, WESLEY W., AND FRED N. WHITE. Physiological thermoregulafion in turtles. Am. J. Physiol. 22 l(3) : 704-7 10. 17 I. .The physiological capacity of turtles for altering rates of heat exchange was partially assessed by measuring rates of change of body temperature (Tb) during heating from 10 C to 30 C, and during cooling from 30 C to 10 C, in both air and water. In water, turtles heated ...

In this study, a new proposed multi-generation system as a promising integrated energy conversion system is studied, and its performance is investigated thermodynamically. The system equipped with parabolic trough collectors and biomass combustor to generate electricity, heating and cooling loads, hydrogen and potable water. A double effect absorption chiller to provide cooling demand, a proton...

Geothermal energy piles (GEPs) are an environmentally friendly heat exchange technology that dualizes the role of structural foundation pile for load support and in meeting building heating/cooling need. Energy loops made from high-density polyethylene, which allow carrier fluid circulation, fitted into elements to extract or inject store soil surrounding pile. This paper reports results a nume...

A new type of district energy network capable of providing simultaneously heating and cooling is being investigated. It is based on the use of CO2 as a heat transfer fluid by taking advantage of the latent heat of vaporization, to store and transfer heat across the network. The goal of the present study is to determine the performance of a CO2 network when applied to a real urban area. It focus...

This paper is published by Euroheat & Power. Our aim is to inform about district heating and cooling as efficient and environmentally benign energy solutions that make use of resources that otherwise would be wasted, delivering reliable and comfortable heating and cooling in return.

A predictive functional control (PFC) technique is applied to the temperature control of a pilot-plant batch reactor equipped with a mono-fluid heating/cooling system. A cascade control structure has been implemented according to the process sub-units reactor and heating/cooling system. H p c m d

The mau requirements of arrcraft static tests are stated. The extent and effects of kinetx heating are described, and various methods of simulating and controlL.ng heatug In the laboratory are discussed. The further problem of kin&x cooling leads to the technique of heating and cooling by convection where the heating rate 1s low. Xecsurenents and test observations are d~s-cussed with reference ...

A moving metallic plate subject to heating and cooling boundary conditions is considered in this work. The plate is heated by an imposed heat  ux, and cooled down by an array of impinging jets through convection and radiation. The objective of the present work is determination of operating conditions for controlling the temperature distribution at the end of both heating and cooling sections. ...

This paper discusses the theory and experiments of heating and air cooling of battery modules. The heating mechanisms are shown first. Then, cooling of a single battery is examined. Optimum air flow speed is discussed. © 2014 The Authors. Published by Elsevier Ltd. Peer-review under responsibility of the Scientific Committee of IICST 2014.
