Heating and cooling systems
Heat exchangers are technical devices which are used to transfer thermal energy from one medium to another. Usually the heat exchangers use water, but sometimes other fluids and even solids may be utilized. Normally the function of heat exchangers is to maintain heat during ventilation or passive cooling. In addition, heat exchangers are used to recycle heat from engines and exhaust gas.
A heat exchanger helps to transfer heat from one liquid or gas to another. Some types of heat exchangers mix the two different liquids, but other types include a solid wall which separates the liquids and prevents them from mixing. In addition, heat exchangers are available in which so-called fins are used in connection with the wall to increase the surface while reducing the resistance. To make the most efficient heat exchangers possible, usually the wall space between fluids must be maximized while minimizing fluid flow resistance. JUMO's temperature and pressure sensors control and monitor the process.
