Description

<p>Variable refrigerant flow (VRF) heat-pump systems are quite popular in Japan, and their efficiency affects energy consumption. In this study, the actual conditions of VRF heat-pump systems were evaluated by analyzing data obtained during maintenance operations. The data showed that the performances of the systems were affected by the partial load rate. In particular, during hot seasons, a low partial load resulted in a low energy efficiency. Considering 30% of measured outdoor units, the maximum heat load in the cool season was lower than 0.5. This indicates the possibility of reducing the cooling capacity, which can in turn reduce the heating capacity and increase the system efficiency.</p>
