“…The first step is the selection of the weather conditions that are boundaries of the test sequence. Then, a short sequence is defined with a clustering classification (Menegon et al, 2017a). The main advantage is that different climates can be easily selected to define the test sequence.…”

Dynamic whole system testing methods are applied to evaluate the performance of heating system driven by renewable energy. The application of dynamic methods is needed to perform a reliable performance evaluation since these systems work under dynamic conditions. However, some procedures described in literature are defined for a specific application.The PLPE procedure has been developed with the aims of simplification of its application and of having a general applicability. Nevertheless, the PLPE was validated only for a solar assisted heat pump system. The present paper wants to investigate the applicability of the PLPE procedure for the test of a solar cooling system. The paper shows the representability of the emulations and the accuracy of estimating the seasonal performance for different climates in the case of solar cooling systems. The PLPE can estimate the thermal SPF with an accuracy of the 10%.

“…The CCT does not foresee any other climate in order to perform a benchmark test for the different systems that are tested. Differently, the PLPE applies a clustering methodology to define the short boundary condition for a climate that the user can choose (Menegon et al, 2017a). With this method, the user can also choose to variate the length of the test sequence.…”

To perform a reliable performance evaluation under realistic boundary conditions, in the last twenty years, different research institutes have developed and applied whole system test methods. The methodologies are based on a common approach but the literature presents several differences on the steps that compose the test methods. This leads to different advantages and drawbacks. The paper compares two methodologies in order to investigate on the different results that could be obtained in the same conditions applying two different methodologies. In this paper, we analyze the difference between the CCT method and the PLPE method in terms of boundary conditions (test sequences and load) and present a common application case. Despite the different procedures in the definition of test sequence and emulations, the two methods bring to similar results in the characterization of the seasonal performance of a solar and heat pump system. The CCT method estimates a SPF of 4.09 while the PLPE 4.13.
