Heat exchanger - Wikipedia

A heat exchanger is a system used to transfer heat between two or more fluids.Heat exchangers are used in both cooling and heating processes. The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. They are widely used in space heating, refrigeration, air conditioning, power stations, chemical plants, petrochemical plants, petroleum refineries, natural

Practical Fundamentals of Chemical Engineering - EIT

R = the gas constant, whose value depends on the units of P, V, n, and T T = absolute temperature of the gas The equation may also be written as PV=nRT Where = (V/n) is the molar volume of the gas. A gas, whose P-V-T behavior is well represented by the above equation, is said to behave as an ideal gas or perfect gas. 4.2.2 Standard conditions

Evacuated Tube Solar Collector - an overview

Evacuated tube solar collectors operate in a different way from the collectors presented so far. These usually consist of a heat pipe inside a vacuum-sealed glass tube. As the area of one tube is small, to increase the heat collection area a number of tubes are connected to one manifold although just one tube is shown in Fig. 8.Depending on the collector size 1020 tubes are used.
