Novel ventilation cooling system for reducing air conditioning use in buildings.

Author(s) : TURNPENNY J. R., ETHERIDGE D. W., REAY D. A.

Summary

The paper describes the construction and testing of a latent heat storage system which uses a novel combination of night cooling, heat pipes and phase change materials (PCMs) and has the distinct advantage that it is suitable for fitting to existing buildings. The design of the heat pipe/PCM heat storage unit is briefly discussed. The test rig was constructed in a room of approximately 14 m2 floor area, and consisted of a number of heat pipe/PCM units mounted radially close to the ceiling with forced convection from a large propellor fan. Test results from the prototype over a range of summer weather conditions are presented. The advantages of the system compared to existing concrete beam systems are briefly described.
