2熱源駆動一重二重効用併用型吸収式冷凍機の特性 第3報 : 吸収溶液循環流量の操作による高効率運転に関する検討 Characteristics of Single/Double-Effect Combination Absorption Refrigerator 3rd Report : Study on high efficiency operation by absorbent flow rate control
This report refers to the single/double effect combination absorption refrigerator (parallel flow type), which is driven by waste heat from fuel cells, and investigates its characteristics whenthe solution flow rate and the distribution ratio of solution are controlled. Since the waste heat of fuel cells can be recovered in the form of steam and warm water, this absorption refrigerator utilizes them both simultaneously, and can thereby be applied to year-round cooling.<br>In controlling the solution flow rate and distribution ratio of solution, it becomes necessary to clarify the conditions under which the above factors are controlled. The extent to which these conditions can be satisfied becomes the domain in which the operations can be undertaken. Therefore the domain is clarified, and it is shown that an operating point at which the cooling capacity is greatest does exist. In addition to this, it is stated that this operating point varies according to the operating conditions. As a result, an indicator of the high efficiency operation of the absorption refrigerator due to the control of the solution flow rate, and distribution ratio of solution is obtained.
