<p><P>PROBLEM TO BE SOLVED: To provide a system which effectively recovers unused energy in a heat storage type air conditioning system having a storage pump. <P>SOLUTION: A heat storage type air conditioning system includes a heat storage tank 16 for manufacturing heat at an upstream, and a heating source machine 4, and manufactures cold water or warm water by utilizing cheap commercial power supplies 18 such as night time electrical power. A system linkage device 20 is formed between a motor 2 and a power supply 19 which actuate the storage pump 1. The system linkage device and the motor 2 are connected via a cable 21. Furthermore, an output of the inverter is connected to the motor 2 via a cable 14a. The system linkage device 20 operates in a direction supplying electric power to the motor 2 from a commercial power source 19 while a water wheel does not operate, and operates in a direction covering electric power wile adding commercial power supply if electric power generated by a generator 13 is not sufficient depending on a load condition of the storage pump 1 while the water wheel operates. When generated electric power is surplus, surplus electric power is fed back from an inverter to the commercial power supply through the system linkage device. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
