Toplinske pumpe

Ovaj diplomski rad opisuje rashladne sustave s mogućnošću hlađenja, grijanja i ventilacije ili ukratko toplinske pumpe. Opisuju se osnovne komponente takvih sustava: kompresor, isparivač, kondenzator, prigušni element i radna tvar. Radna tvar je plin ili kapljevina koja se najviše proučava i prilagođava ekološkim zahtjevima današnjice (smanjenje štetnog utjecaja na ozonski omotač, manji troškovi proizvodnje). Vrlo bitan faktor je energetska učinkovitost toplinskih pumpi pa se u ovom radu navodi i klasifikacija uređaja po faktoru hlađenje, odnosno toplinskom množitelju.This thesis describes air conditioning systems that provides heating, ventilating, and air conditioning, called heat pumps. It describes basic components of such systems: compressor, evaporator, condenser, expansion valve and refrigerant. Most studies are done on refrigerant, gas or liquid, in order to adjust heat pumps to new ecological requirements (lowering adverse effect on ozone layer, reduction of production costs). Big importance of energy efficiency coefficient of heat pumps is described in this thesis and also listed classification based on energy efficiency ratio and coefficient of performance
