Cooling water is supplied through a supply pipe during the heating/hot water supply preheating mode and hot water supply preheating mode, and hot water is supplied through the supply pipe during the heating mode, and the cold/hot water that has passed through the water heat exchanger for hot water supply returns through the return pipe. In an air conditioning system for a residential building equipped with a device, a bypass pipe connects the supply pipe and the return pipe in parallel with the cold/hot water inlet/outlet of the water heat exchanger for hot water supply, and a cold/hot water supply amount arranged in the bypass pipe. An adjustment water supply valve, a temperature detection sensor disposed at the cold/hot water outlet of the water heat exchanger for hot water supply, and a temperature detected by the sensor that is input during each of the cooling and hot water preheating, heating and hot water preheating, and hot water preheating modes. Outputting a closing signal to the water supply valve when the temperature detected by the sensor input during the heating mode is equal to or higher than a preset first threshold value and when the temperature is equal to or lower than a preset second threshold value, and and a control unit that stops outputting the closing signal when the temperature detected by the sensor becomes lower than the first threshold value or higher than the second threshold value in each mode. This air conditioning system for residential buildings is characterized by:
