LOW TEMPERATURE HOT WATER DRIVEN SINGLE EFFECT DOUBLE LIFT ABSORPTION REFRIGERATOR WITH IMPROVED HEAT EXCHANGER ARRANGEMENT

摘要

The present invention relates to a cold water two-stage absorption chiller suitable for a mall or apartment in a district heating area, and more specifically, an auxiliary regenerator is disposed at an upper part and an auxiliary absorber is located at a lower part for a secondary cycle that was conventionally installed therebetween. The cold water two-stage absorption chiller having an improved heat exchange arrangement structure configured to reduce the production cost and the operating power cost by removing the concentrate pump. According to the present invention as described above, an auxiliary regenerator is positioned at the top of the apparatus and an auxiliary absorber is disposed at the bottom of the apparatus. It is possible to reduce the manufacturing cost and operating power cost by configuring the auxiliary concentrate to be supplied to the auxiliary absorber through the auxiliary heat exchanger from the auxiliary regenerator only by gravity without installing the auxiliary concentrate pump by arranging the auxiliary concentrate pump.;Absorption Chiller, District Heating, Auxiliary Concentration Pump, Auxiliary Heat Exchanger, Gravity, Cost Reduction
