The optimization of the mechanical night cooling system in office buildings.

Author(s) : LAIN M., HENSEN J.

Summary

The need of optimization for the mechanical night cooling system was discussed in many cases. The paper deals with the use of computer simulations both for the design support of a new building and HVAC system development and for the optimization of the system control strategy in the finished building. In an early design of a new commercial building in Prague, computer simulations were carried out to prove possible effects of night cooling ventilation. Predictions of the indoor environment and energy consumption for optional solutions regarding cooling capacities and different rates of ventilation by outdoor air helped to design an air-conditioning system, which comprises of daytime top cooling and night ventilation by outdoor air combined with accumulation of cold in building constructions. Long-time monitoring and further computer simulations were performed in order to optimize the control strategy for the top cooling system.
