HEAT EXCHANGER FOR IN-GROUND HEAT STORAGE
Chemical Engineering Communications, 1980The first phase of a research project using undisturbed soil for sensible heat storage is described. A laboratory scale model of a heat exchange system was constructed and tested. Thermal charging and recovery rates, modes of heat transport and transient temperature conditions, as well as over-all heat storage performance of the unit are given.

Matériaux & Techniques, 1992
Plastic properties may be used in the manufacturing of heat exchangers. Considering their advantages, their field of application is quite large: low temperature heat recovery, concentration of solutions. Three equipment are described: a liquid-liquid shell and tube exchanger, a gas-gas shell exchanger and a falling flow evaporator.

The Laryngoscope, 1981
AbstractStudies of the effects of nasal respiration on the lower respiratory tract, and on metabolic processes generally, have largely been confined to those occurring during inspiration. Expiration through the nose has equally profound effects and has been studied in detail in some animals.Under certain circumstances both heat and water loss from the ...

Turbulent flows in a spiral double-pipe heat exchanger
International journal of numerical methods for heat & fluid flow, 2019Purpose This paper aims to study the fluid flow and heat transfer through a spiral double-pipe heat exchanger. Nowadays using spiral double-pipe heat exchangers has become popular in different industrial segments due to its complex and spiral structure,

Heat exchangers are used to transfer heat from a hot fluid to a cold fluid. In general, the two fluids flow through appropriate channels (tubes, spaces between parallel plates or between tubes) within the equipment. Solid surfaces made of metal or, less often, of some polymer (teflon, e.g.) separate the fluids.

The research of optimal design of heat exchanger in heat exchanger heat meter
Proceedings of 2011 International Conference on Modelling, Identification and Control, 2011In heat exchanger heat meter, the heat exchanger is equivalent to a flowmeter. The flow and heat can be calculated by measuring the inlet and outlet temperature of heat exchanger. It greatly prevents the flowmeter from the problem of inaccuracy and damage which are caused by the quality of water.
