Abstract This study investigates energy-efficient design solutions for secondary equipment rooms in renewable energy integration stations, employing the typical climate of Ningxia in Northwest China as the temperature condition for simulation. Through numerical simulations, the temperature regulation ability and energy-saving effects of phase-change energy storage materials (PCMs) on the building body of the secondary equipment room were explored, providing data support for practical construction. Three typical climates within a year were selected for simulation, and the results showed that applying PCM panels to indoor walls exhibited remarkable advantages compared to ordinary concrete walls without PCM. Specifically, PCMs help reduce the interior temperature fluctuation of the secondary equipment room, keeping the room at comfortable temperatures for a significantly prolonged duration. The walls with PCMs can store more heat, which enables the room to resist external temperature changes and further reduce the energy consumption of indoor HVAC systems. In terms of energy-saving results, PCMs have optimal effect in summer, moderate effect in spring and autumn, and insignificant effect in winter. This indicates that the effect of PCMs is closely related to the environmental temperature variations and the selection of phase change temperatures. Practical applications should also consider additional factors to make effective use of PCMs.
