Ziel dieses Buches ist es, die thermische Leistung und die Machbarkeit der Integration eines Erd-Luft-Wärmetauschers (EAHE) in das Dampfkompressions-Luftkühlsystem eines Gebäudes im hei en Klima der arabischen Golfregion oder in ähnlichen Klimazonen zu bewerten. Bei dem vorgeschlagenen System wird die Umgebungsluft von einem Axialventilator durch einen in einer bestimmten Tiefe unter der Erdoberfläche vergrabenen EAHE gedrückt. Der EAHE nutzt die niedrige Temperatur des Untergrunds und die thermischen Eigenschaften des Bodens, um die Temperatur der Kühlluft zu senken. Die Abluft aus dem EAHE wird zur Kühlung des Kondensatorregisters einer Klimaanlage auf Basis des Dampfkompressionszyklus (VCC) verwendet, um deren Leistungszahl (COP) zu verbessern. Die potenzielle Verbesserung des COP wurde für zwei verschiedene Kältemittel (d.h. R-22 und R410a) in Kühlsystemen untersucht. Es wurde ein mathematisches Modell entwickelt, um die Bodentemperatur in verschiedenen Tiefen zu schätzen, und die entsprechende Luftaustrittstemperatur des EAHE wurde berechnet.
