This study was compared the experiment results with Flowmaster V7 results using a simple mock-up model, in order to examine the applicability of the Flowmaster V7 in the performance prediction of cooling and heating circulation system. As a result of comparison, error rate of the inlet pressure has been calculated to be 0.07 ~ 12.86%, and the average error rate was to be 4.66%. The outlet pressure was 0.00 ~ 6.14%, and the average was 2.38%. The flow rate was 0.02 ~ 9.29%, and the average was 4.66%. The RPM of pump was 0.79 ~ 5.12%, and the average was 3.00%. All four results showed high accuracy by less than 10.00%. Electric power consumption of the pump was calculated the error rate to be 0.19 ~ 23.00%, and the average error rate showed a low accuracy to be 9.60%. But, both experiment and Fowmaster V7 showed similar characteristics.

본 연구에서는 냉·난방 순환계통의 시스템 예측에 있어 시뮬레이션의 적용 가능성을 검토하기 위해 간이 mock-up모델을 이용하여 실험 및 시뮬레이션 결과를 비교하였다. 비교결과 압력은 최대 15.88%, 최소 0.00%, 유량은 최대 11.97%, 최소 0.02%, 펌프의 회전수는 최대 5.12%, 최소 0.79%의 오차율을 보였다. 실험 중 휴먼에러로 사료되는 일부 결과를 제외하면, 대부분 약 10%이내의 오차율을 보였다. 소비전력의 경우 회전수와의 상관관계에서 실험 및 시뮬레이션 모두 유사한 결과를 보였다. 따라서 시뮬레이션을 이용한 냉·난방 순환계통의 시스템 예측이 적합한 것으로 사료된다.
