摘要:
量热计法室内侧制冷量计算公式,未考虑测量中小冷量空调器制冷量时空气处理柜除湿造成的误差。为排除此误差对测试结果的影响,采用称重法分别测量量热计内、外室加湿水及被测机的凝结水。利用基于称重法设计的量热计测得5台被测机的2组数据并进行分析,结果表明,当空调器的额定制冷量低于测试室输入功率时,空气处理柜的除湿量会增大测量偏差,且随着空调器制冷量的降低偏差增大。并对室内侧制冷量计算公式进行修正,以提高计算精确度。

Abstract:
During the cooling capacity measurement of small and medium size air conditioner, the indoor cooling capacity calculation formula of room-type calorimeter didn’t take the dehumidification of air handling cabinet into consideration. In order to eliminate the impact of this influence on the test results, the mass weighing method was proposed to measure the humidification water of inner and outer chamber of the calorimeter, as well as the condensate water of air conditioner under test respectively. By analyzing the two sets of test results of five test units which were tested by means of room-type calorimeter based on the mass weighing method: It turns out that, when the rated cooling capacity of the air conditioner under test is smaller than the input power of the test chamber, the test error is increased by the air handling cabinet’s dehumidification amount, and the test error arises with the decrease of cooling capacity of air conditioner. The indoor cooling capacity calculation formula is modified to improve its accuracy according to the test results.
Key words:  room-type calorimeter  weighing method  condensate measurement  validation
