Dans la conception de l'évaporateur-absorbeur en deux étages, l'évaporateur et l'absorbeur sont divisés en sections inférieure et supérieure. YORK® YHAU-CW Double-effect, Steam-fired Absorption Chillers offer a broad range of capacities from 120 to 4,000 TR. The principle behind an absorption process is to separate and recombine to fluids (refrigerant and absorbent) to create a cooling effect. A chiller is a machine that removes heat from a liquid via a refrigeration cycle. The chiller consists of an open motor mounted to a compressor (with integral speed increasing gears) condenser, cooler and vari-able flow control. In the 2-step evaporator-absorber design, the evaporator and absorber are split into lower and upper sections. Please use this form to submit an inquiry. Par conséquent, l'absorption nécessite des températures de générateur plus basses - qui produisent moins de gaz incondensables et moins de fréquence de purge. Cela crée deux niveaux de pression différents, améliorant l'absorption par rapport à un cycle conventionnel. Cette combinaison assure un fonctionnement plus loin de la ligne de cristallisation (29 ° C / 84 ° F), améliorant ainsi la fiabilité de fonctionnement. This creates two different pressure levels, enhancing absorption compared to a conventional cycle.
