Analysis of operational performance of a mechanical ventilation cooling system with latent thermal energy storage

摘要: Abstract Latent Thermal Energy Storage (LTES) is a promising solution to reduce cooling energy consumption in buildings. Laboratory and computational studies have demonstrated its capabilities while commercial passive active systems are available. This paper presents data analysis of the performance an LTES ventilation system two case-studies, seminar room open plan office UK. Analysis using environmental from system’s control as well additional space monitoring indicates that (a) internal temperature maintained within adaptive thermal comfort limits, (b) acceptable Indoor Air Quality also (using metabolic CO2 indicator) (c) costs low compared air-conditioned CFD indicate purging charging duration associated set-points for air flow rate important parameters optimised given design. These should be according use prevailing external conditions maintain upper (usually afternoon) lower morning) limits.
