PROBLEM TO BE SOLVED: To provide an air conditioner and an air conditioning system capable of sophisticated temperature/humidity control with a simple configuration.SOLUTION: An air conditioner includes: a cold water coil 4 to which cold water for cooling/dehumidification is supplied from a cold source device, and including a cold water control valve； and a hot water coil 6 to which hot water for heating/re-heating is supplied from a heat source device, and including a hot water control valve. The cold water coil is constituted by two cold water coil units 4a water volumes of which can be independently controlled by the cold water control valve, respectively, and arranged in front of the hot water coil in parallel. The cold water coil, the hot water coil, an air fan 14, and a humidifier 15 are incorporated in a casing 11. A temperature/humidity sensor 20 is disposed at a position near an air inlet within the casing. The air conditioner, which is arranged at a position facing an operation room 1, sucks in return air RA and blows out processed supply air SA into the operation room. Outdoor air OA is treated by an outdoor unit 25 and blown out into the operation room.COPYRIGHT: (C)2014,JPO&INPIT【課題】簡易な構成で高度の温湿度制御が可能な空調機および空調システムを提供する。【解決手段】冷熱源装置から冷却・減湿用の冷水が供給される冷水制御弁を備えた冷水コイル４と、温熱源装置から加熱・再熱用の温水が供給される温水制御弁を備えた温水コイル６を具備してなり、冷水コイルをそれぞれが冷水制御弁によって独立に水量制御可能な２台の冷水コイルユニット４ａにより構成して温水コイルの前段に並設する。ケーシング１１内に冷水コイル、温水コイル、送風機１４、加湿器１５を組み込む。ケーシング内の吸込口の近傍位置に温湿度センサー２０を設置する。上記空調機を手術室１に面する位置に配置して還気ＲＡを吸引し、調製した給気ＳＡを手術室に吹き出す。外調機２５により外気ＯＡを処理して手術室に吹き出す。【選択図】図１
