As one type of perimeter air conditioning (AC) systems, there is a through-wall unit (TWU) that processes perimeter heat by exchanging heat with an outdoor fan from an exterior grill on the outer wall of a building. In this study, we improved the TWU by adding a new operation mode to cascade-use room exhaust air for the compressor heat exchange and developed a high efficiency perimeter air-conditioning system. This paper shows the outline of the new air-conditioning system by combining various operation patterns of the TWU. This enables selection corresponding to various air-conditioning needs in an office building, and it improves comfort and saves energy. In addition, the TWU exhaust performance tests of a sash shape model and a full scale model were carried out. From the viewpoint of exhaust performance when using a TWU in a high-rise building, and achieving the necessary cooling and heating capacity, it was confirmed that this would perform well.
