CAPACITY DIAGNOSIS SYSTEM AND CAPACITY DIAGNOSIS METHOD FOR ABSORPTIVE REFRIGERATOR

PROBLEM TO BE SOLVED: To enable capacity diagnosis even in low refrigeration output, in a case where refrigeration output of an absorptive refrigerator is low.SOLUTION: A system for diagnosing capacity of an absorptive refrigerator includes an absorber, an evaporator, a regenerator, a condenser and a heat source configured to heat the regenerator; and uses cold water cooled by the evaporator and cooling water for removing heat generated in at least one of the absorber and condenser. The system has a calculator configured to calculate refrigeration output using the difference between an inlet temperature and an outlet temperature of the cold water, and calculate a ratio of predetermined temperature difference and refrigeration output. The system is configured to diagnose refrigeration capacity using the ratio.SELECTED DRAWING: Figure 2 【課題】吸収式冷凍機の冷凍出力が低下した場合に、冷凍出力が低い状態でも能力診断を可能とする。【解決手段】吸収器と、蒸発器と、再生器と、凝縮器と、再生器を加熱する加熱源と、を備え、蒸発器で冷却される冷水と、吸収器及び凝縮器のうち少なくともいずれか一方で発生する熱を除去する冷却水と、を用いる、吸収式冷凍機の能力を診断するシステムにおいて、冷水の入口温度と出口温度との差を用いて冷凍出力を算出し、所定の温度差と冷凍出力との比を算出する演算装置を有する。上記の比を用いて冷凍能力を診断する。【選択図】図２
