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.

This chapter provides a review of the methods used in the thermal analysis of heat exchangers. Equipment used in double-pipe (hairpin), shell-and-tube, and plate heat exchangers is described. The overall heat-transfer coefficient, fouling factors, LMTD (logarithmic mean temperature difference) correction factor, and heat-exchanger effectiveness are ...

Metal Finishing, 1995
Fluoropolymer heat exchangers are the only polymeric heat exchangers to offer thetemperature capabilities and corrosion resistance necessary to heat and cool acid- and caustic-based plating baths. They offer economical solutions to the problems of maintaining precise temperature control of baths for optimum product quality.

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 ...

Dynamic models for heat exchangers and heat exchanger networks
Computers & Chemical Engineering, 1994Abstract Dynamic models are needed to assess controllability of heat exchangers and heat exchanger networks. A simple model is desirable, but all important model features must be included. We discriminate between important and less important model features by order of magnitude argumentation, comparison of controllability measures and dynamic ...

: Briefly summarized what is commonly referred to as classical thermodynamics, a young science that relies mainly on what should be more appropriately qualified as equilibrium thermodynamics or thermostatics (by analogy with statics in mechanics, electrostatics, magnetostatics, chemical equilibrium, etc.).

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.

Stream-Symmetry of Heat Exchangers and Heat Exchanger Assemblies
Heat Transfer Engineering, 1984Sufficient conditions are given for a heat exchanger or an assembly of heat exchangers to be invariant under the interchange of the two fluids. Analysis of this symmetry is performed on tht basis of geometrical or topological properties of the exchanger, and no prior knowledge of the exchanger solution is required.
