特開2020-67200号公報Japanese Unexamined Patent Publication No. 2020-67200

この放射空調機の熱交換器は、熱交換用水の下限通水量の制御が難しく低空調負荷の場合、能力過多となって冷やし過ぎや温め過ぎが生じ、省エネ性と快適性に問題が生じやすかった。 In the heat exchanger of this radiant air conditioner, it is difficult to control the lower limit of the amount of water for heat exchange, and if the air conditioning load is low, the capacity will be excessive and overcooling or overheating will occur, which may cause problems in energy saving and comfort. rice field.

本発明は上記課題を解決するため、熱交換器を有するコイルユニットと、室内空気と屋外空気の一方又は両方を前記コイルユニットに取込んで前記熱交換器で熱交換して空調用空気として送風するファンユニットと、前記ファンユニットから送風された前記空調用空気を室内に給気する給気ユニットと、前記コイルユニットと複数台の前記ファンユニットとをつなぐ送風ダクトと、制御装置と、を備え、前記熱交換器が、熱交換用水が通水される伝熱管群を複数のグループに分配しかつ一部又は全部の前記グループの前記熱交換用水の限界通水量の割合が異なるように分配した分流回路を、備え、前記制御装置が、前記室内が低空調負荷の場合に前記分流回路の最少限界通水量の第1の前記グループで前記熱交換用水の通水量を増減させる空調負荷対応部を、備え、前記熱交換器を通過する空気の気流方向から見たときに、前記分流回路の前記第1グループを除いた第2の前記グループに、前記第1グループと重ならない不重複ゾーンが、形成されるように構成すると共に、前記第1グループが前記不重複ゾーンで挟まれるように前記分流回路を構成したことを最も主要な特徴とする。 In order to solve the above problems, the present invention takes in one or both of a coil unit having a heat exchanger and indoor air and outdoor air into the coil unit, exchanges heat with the heat exchanger, and blows air as air conditioning air. A fan unit, an air supply unit that supplies air for air conditioning blown from the fan unit into the room, a blower duct that connects the coil unit and a plurality of the fan units, and a control device. , The heat exchanger distributes the heat transfer tube group through which the heat exchange water is passed to a plurality of groups and distributes a part or all of the heat exchanger so that the ratio of the limit water flow amount of the heat exchange water of the group is different. The control device is provided with an air-conditioning load corresponding unit that increases or decreases the amount of heat exchange water in the first group of the minimum limit water flow of the diversion circuit when the room has a low air-conditioning load. When viewed from the direction of the flow of air passing through the heat exchanger, the second group excluding the first group of the diversion circuit has a non-overlapping zone that does not overlap with the first group. The most important feature is that the first group is configured to be formed and the diversion circuit is configured so that the first group is sandwiched between the non-overlapping zones.

請求項1の発明によれば、低空調負荷の場合に熱交換器の分流回路の第1グループで熱交換用水の通水量を増減させて下限通水量をさらに最少化できる。そのため、熱交換器の下限能力制御範囲が広がって低空調負荷の場合でも能力過多とならず、エネルギー浪費及び冷やし過ぎや温め過ぎが無くなって省エネ性と快適性が向上する。
冷房時に熱交換用水を熱交換器の分流回路の第1グループに流通させて第2グループに流通させないようにし、第1グループを通過して過冷却除湿した空気を、不重複ゾーンを通過した前記過冷却除湿空気よりも高温のバイパス空気で再熱し、不快な冷感がないドライエアーを得ることができる。このとき、前記過冷却除湿空気が逃げないように前記バイパス空気で挟むので混合が促進されて確実に再熱することができる。そのため、湿度が高くてジメジメする中間期でも、コールドドラフトのないカラッとした気流で空調ができ快適性が向上する。しかも、バイパスダンパ等の機器が不要でコストダウンとコンパクト化を図れる。
According to the first aspect of the present invention, in the case of a low air conditioning load, the lower limit water flow rate can be further minimized by increasing or decreasing the water flow rate of the heat exchange water in the first group of the heat exchanger diversion circuit. Therefore, the lower limit capacity control range of the heat exchanger is widened, and even in the case of a low air-conditioning load, the capacity is not excessive, energy wasted, and overcooling and overheating are eliminated, and energy saving and comfort are improved.
During cooling, the heat exchange water is circulated to the first group of the heat exchanger's diversion circuit so that it is not circulated to the second group, and the overcooled and dehumidified air that has passed through the first group has passed through the non-overlapping zone. It is possible to obtain dry air without an unpleasant feeling of cold by reheating with bypass air having a temperature higher than that of supercooled dehumidified air. At this time, since the supercooled dehumidified air is sandwiched between the bypass airs so as not to escape, mixing is promoted and reheating can be reliably performed. Therefore, even in the middle period when the humidity is high and it is damp, air conditioning can be performed with a crisp air flow without cold draft, and comfort is improved. Moreover, equipment such as a bypass damper is not required, and cost reduction and compactness can be achieved.

請求項3の発明によれば、給気ユニットで空調用空気と室内空気を誘引混合して、混合空気の温度を室内の温度に近づけることができるため、コールドドラフトがなく冷房時の結露防止効果が得られる。誘引放射ユニットの熱放射の作用によりドラフト感や温度ムラがなく快適性が向上する。
According to the second aspect of the present invention, the fan units (the number of units smaller than the total number) in the room can be used to control the air flow amount (supply air amount) for arbitrary time air conditioning, or the total number of fan units can be increased from the maximum. The entire building can be air-conditioned for 24 hours by controlling the minimum amount of air to be blown.
According to the third aspect of the present invention, the air supply unit can attract and mix the air conditioning air and the indoor air to bring the temperature of the mixed air close to the indoor temperature, so that there is no cold draft and the effect of preventing dew condensation during cooling is achieved. Is obtained. Due to the action of heat radiation of the attract radiation unit, there is no draft feeling or temperature unevenness, and comfort is improved.

請求項5の発明によれば、蒸気加湿なので加湿不足がなく快適性が向上し、加湿暖房もできる。
請求項6の発明によれば、伝熱管群の通風抵抗が小さくてさらに省エネとなり、熱交換効率が向上するので、熱交換器及びコイルユニットの小型化を図れる。
According to the invention of claim 4, the energy saving performance can be further improved by the total heat exchanger.
According to the invention of claim 5, since it is steam humidification, there is no insufficient humidification, comfort is improved, and humidification and heating can be performed.
According to the invention of claim 6, since the ventilation resistance of the heat transfer tube group is small, energy saving is further improved, and the heat exchange efficiency is improved, the heat exchanger and the coil unit can be miniaturized.

請求項7と8の発明によれば、通常一体設置されているコイルユニットとファンユニットを分けてセパレート化して各室に分散設置し、床下や屋外に熱源装置を設置するので、生活スペースが無駄に制限されず、保守点検も容易となる。
請求項8の発明によれば、熱源装置が、エクセルギーの高い室内空気を混ぜて熱源用空気として利用するので、デフロスト運転の軽減と熱交換用水の温度調整能力の高効率化を図れる。
