OPTIMAL CONTROL OF CIRCUIT TYPE DOUBLE SKIN FAÇADE USING EXHAUST HEAT OF AIR CONDITIONING SYSTEM IN A CASCADE MANNER

Abstract

We verified the basic performance of the circuit-type double skin, which uses air-conditioning exhaust from the subject building and adjacent building, based on unsteady CFD analysis. Furthermore, we proposed the control method to improve the dynamic actual operation performance of this double skin and clarified its effectiveness by unsteady CFD analysis. Following results were obtained.

1. Air temperature in double skin was stabilized and heat-load was reduced by cascade use of air conditioning exhaust.

2. Introduction of the proposed optimal control method further improved the reduction effect of the thermal transmission load.
