The partial load performance tests of multi-type package air-conditioner for buildings, the rated cooling performance of which was 56kW, were carried out by using the air-enthalpy method testing apparatus. The annual energy consumption measured by those tests was closely compared with that estimated from the current calculating method. It was found that the current calculating method could not reproduce the deteriorations of COP that appeared under the low thermal load condition in both the cooling and heating seasons. As a result it seriously underestimated the annual energy consumption ; the error amounted to as large as about 20% of the measured annual electric power consumption.
