SIMULATION OF A NOVEL HEAT PIPE/PCM SYSTEM FOR COOLING OF NATURALLY VENTILATED BUILDINGS

The paper describes the numerical simulation of a novel ventilation cooling system. The ultimate aimof the mathematical model is to facilitate the design of the system for specific buildings and climates.The model directly takes account of time dependency in that the diffusion equation for the heat flow inthe fabric of the room is solved. This approach means that important parameters (e.g. ventilationrates and internal heat gains) can be arbitrarily specified as functions of time.
