Abstract

PURPOSE:To reduce the number of parts for pipe joints and construction components for obtaining an air conditioner with a hot-water supply unit which is small in size, light in weight and low in cost and does not require to strengthen construction members of the hot-water supply unit, by stacking the hot-water supply unit on top of an outdoor unit to integrate them into one body. CONSTITUTION:An air conditioner with a hot-water supply unit is furnished with a fan support 6, a separator 7, hot-water supply unit base support 10 and a hot-water supply unit base 11 as construction members by which a hot-water supply unit is stacked on top of an outdoor unit to integrate them into one body. Newly provided construction components for integrating the hot-water supply unit and the outdoor unit into one body include a hot-water supply unit cabinet 3, a hot-water supply unit base support 10, hot-water supply unit base 11, an erect cover 13, an electric control box 16 for hot-water supply unit and a joint holder 21. Therefore, it is not necessary for the construction members to be separately provided for the outdoor unit and the hot-water supply unit, so that the number of parts can be reduced. And also, as it is unnecessary for the construction members of the hot-water supply unit to increase their strength, the hot-water supply unit can be built smaller in size and lighter in weight. Thereby, the entire outdoor unit 1 can be made smaller in size and lighter in weight.
