Air conditioning apparatus

An air conditioning apparatus which increases a room temperature by supplying a fluid heated by a heat pump device to a heat exchange device installed in a room, comprising:

• a hot water outflow temperature detection part which detects a hot water outflow temperature being a temperature of the fluid after being heated by the heat pump device;
• a return temperature detection part which detects a return temperature being a temperature of the fluid before being heated by the heat pump device;
• a temperature difference checking part which checks whether or not a temperature difference between the hot water outflow temperature detected by the hot water outflow temperature detection part and the return temperature detected by the return temperature detection part is smaller than a predetermined first threshold;
• and
• a notification part which, when the temperature difference checking part judges that the temperature difference is smaller than the first threshold, notifies that the heat exchange device has a heat dissipation amount that is insufficient.
