Abstract |
The basic facility efficiency of a small building was represented by a value at the time of rated power, but it is difficult to evaluate the actual energy consumption or calculate the energy consumption by the period load, so Europe and the United States are converting it to the period energy efficiency. Considering this trend, the period efficiency of each mode is applied in Korea, but despite similar devices, the evaluation methods are all different. In particular, the applicable evaluation criteria are insufficient for integrated facilities that are expected to be highly applicable to small buildings. Therefore, it is considered necessary to analyze the processing load mode for integrated facility systems that are expected to be installed in small buildings in the future and evaluate the period energy efficiency of the energy consumption compared to the processing energy. The COP based on monthly total integrated power was 3.1, 3.5, and 4.3, respectively, and the partial load rate was 28.8%, 38.1%, and 71.2%, respectively. In the mid-April and May, the COP of the integrated facility was somewhat reduced when hot water and ventilation were integrated. As a result of the COP analysis of the integrated facility, it was analyzed that when the load amount of the building is calculated, it is possible to predict energy consumption by applying COP according to the change in the partial load rate. |
