Colt CoolShaft is a combined smoke and climate control ventilation shaft system which cleverly uses evaporative cooling technology to provide active pre-cooling of the incoming air, without compromising the ability of the shaft system to ventilate the common area in a fire – and this with exceptionally low energy consumption
We recently carried out CFD modelling of the conditions in a corridor of a multi-storey residential building.

This corridor has a low temperature hot water pipework system shown as the heat source in yellow, which is situated above a false ceiling. Supply air is provided by mechanical plant in the roof plant room, connected to the smoke extract shaft. Air is delivered to each corridor via a small day to day damper at low level in the shaft (below the smoke dampers). Air is exhausted at each corridor level via a small day to day damper within the ceiling void and then extracted by mechanical plant at the head of the stairwell. |

With no ventilation, the predicted temperatures in the corridor at 1.8m above FFL will be at an average of 31C at average summer time temperatures |

With simple ventilation, the predicted temperatures in the corridor at 1.8m above FFL will be at an average of 29C at average summer time temperatures. |

With CoolShaft, the predicted temperatures in the corridor at 1.8m above FFL will be at an average of 23C at average summer time temperatures. |
