<P>PROBLEM TO BE SOLVED: To provide a technology for continuously achieving local air conditioning. <P>SOLUTION: This local environment preservation device includes: a mobile main robot (50A) equipped with a heat exchanger (52) for lowering the temperature of a local space by autonomously moving; mobile sub-robots (60A, 60B, 60C, 60D) mountable to the mobile main robot (50A) and movable independently of the mobile main robot (50A); and a heat pump (70) carrying out heat exchange to the mobile sub-robot (60A). At least one mobile sub-robot (60A) is equipped with a heat accumulator for absorbing heat stored in the heat exchanger (52) when mounted to the mobile main robot (50A). Even when not mounted to the mobile main robot (50A), when the heat accumulator accumulates heat, the mobile sub-robot (60A) autonomously moves to the heat pump (70) to exhaust the heat. <P>COPYRIGHT: (C)2012,JPO&INPIT |
