Temperature and humidity adjusting device and temperature and humidity adjustment method

摘要

PROBLEM TO BE SOLVED: To solve a problem in a conventional temperature/humidity control device that it is difficult to sufficiently save energy.;SOLUTION: In this temperature/humidity control device including two-way valves 20a, 20b for distributing a heat medium of high temperature compressed and heated by a compressor 18 to a heating circuit side including a heater 14 and a cooling circuit side including coolers 16, 16 to control a temperature of the air as a target of temperature/humidity control, and a two-fluid nozzle 15 for controlling a humidity, a compressor control section 60 is disposed for changing a rotational frequency of the compressor 18 so that a distribution ratio of the heat medium of high temperature distributed to a heating flow channel or a cooling flow channel is kept within a prescribed range, and the rotational frequency of the compressor 18 is controlled to be lowered by keeping the air as the temperature/humidity control target under the prescribed temperature and humidity, when the rotational frequency of the compressor 18 is higher than a predetermined set rotational frequency.;COPYRIGHT: (C)2011,JPO&INPIT
