Comfort and energy efficiency of air-conditioning equipment is dependent on the three-dimensional flow in the area where the equipment is installed. On the other hand, selection and layout design of air-conditioning equipment are mainly carried out using one-dimensional heat load calculations, and three-dimensional airflow and temperature simulations are not widely used because it requires height level expert knowledge, high cost, and a large amount of time to use. Mitsubishi Heavy Industries, Ltd. has developed an easy-to-use GPU cloud simulator that can rapidly calculate airflow and temperature. With this cloud simulator, even first-time users can model a typical office conference room in about 20 minutes and complete the simulation in about 3 minutes. Furthermore, when the test results were compared with the predicted results, the practical accuracy of the developed cloud simulator could be confirmed. Consequently, a comfortable air-conditioned environment can be created using this simulator.
