AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2018/070421
Kind Code:
A1
Abstract:
[Problem] To provide an air conditioner that uses less energy to perform a separation treatment for latent heat and sensible heat, and that maintains comfortable indoor temperature and humidity conditions. [Solution] This air conditioner 1 is characterized in that: a latent heat treatment system 3 comprises a latent heat treatment system higher-temperature cold water section 11 where outside air OA and recycled air RA can be cooled/dehumidified, and a latent heat treatment system lower-temperature cold water section 13 where, downstream from the latent heat treatment system higher-temperature cold water section 11, cold water of a lower temperature than the latent heat treatment system higher-temperature cold water 11 can be used to cool/dehumidify the outside air OA and recycled air RA; a sensible heat treatment system 4 comprises a sensible heat treatment system higher-temperature cold water section 12 where cold water of a higher temperature than the latent heat treatment system lower-temperature cold water section 13 can be used to cool/dehumidify the recycled air; and the sensible heat treatment system 4 is further provided with a communicating section 33 that is able to open or close between the latent heat treatment system higher-temperature cold water section 11 and latent heat treatment system lower-temperature cold water section 13 of the latent heat treatment system 3, and open or close a downstream side of the sensible heat treatment system higher-temperature cold water section 12 of the sensible heat treatment system 4, to adjust the volume of passing air.
