口部１ａで混入した高温多湿の空気を予め、除湿冷却器
８でもって除湿を行うものであり、主冷却器７よりも温
度レベルは高くしてありＯ℃近辺で作動するようになっ
ている。In the refrigerated open showcase configured in this way, the hot and humid air mixed in through the opening 1a is dehumidified in advance by the dehumidifying cooler 8, and the temperature level is higher than that of the main cooler 7. It is designed to operate at around 0°C.
従って、第２図に示すように除湿冷却器８の冷媒回路を
なす冷凍ユニット１４ａは主冷却器７のものとは独立し
て設置する方が冷凍効率が高いことは良く知られている
。Therefore, it is well known that refrigeration efficiency is higher if the refrigeration unit 14a forming the refrigerant circuit of the dehumidifying cooler 8 is installed independently of the main cooler 7 as shown in FIG.
そのため凝縮器は、主冷却器のものと独立して設置され
ることが多かった。Therefore, the condenser was often installed independently of the main cooler.
また、凝縮器用送風機１５の電気的接続は、それぞれの
圧縮器１２ ａ 、１２ｂ毎に分かれているため、凝縮
器の構成や送風機の電気的接続が繁雑であった。Further, since the electrical connection of the condenser blower 15 is separated for each of the compressors 12a and 12b, the configuration of the condenser and the electrical connection of the blower are complicated.
本考案は上記点に鑑みてなされたもので、第３図〜第５
図にて以下説明する。This invention was made in view of the above points, and is shown in Figures 3 to 5.
This will be explained below using figures.
図に示すように凝縮器はその側板１６および凝縮器用プ
レートフィン１７を一体的に形成し、凝縮器配管１８．
１９のみ、それぞれの冷凍ユニット毎に分割して配設さ
れている。As shown in the figure, the condenser has side plates 16 and condenser plate fins 17 integrally formed, and condenser piping 18.
Only 19 units are divided and arranged for each refrigeration unit.
また、凝縮器用送風機１５は凝縮器２０の正面に平行し
て設置している。Further, the condenser blower 15 is installed parallel to the front of the condenser 20.
そして、ショーケースの外囲空気の温湿度が低下した場
合、除湿冷却器の温度レベルが低下し、着霜による除湿
冷却器の目詰まりや凍結防止するために冷凍ユニット制
御スイッチ２１ ａが設置されている。When the temperature and humidity of the air surrounding the showcase decreases, the temperature level of the dehumidifying cooler decreases, and a refrigeration unit control switch 21a is installed to prevent the dehumidifying cooler from clogging and freezing due to frost formation. ing.
この冷凍ユニット制御スイッチ２１ ａは、主冷却器７
側の冷凍ユニット制御スイッチ２１ ｂよりも早く運転
が停止するように設定されている。This refrigeration unit control switch 21 a is connected to the main cooler 7
The operation is set to stop earlier than the refrigeration unit control switch 21b on the side.
したがって主冷却器７側の冷凍ユニットは必らず除湿冷
却器８側の冷凍ユニットより稼動率は高くなるので、凝
縮器用送風機１５は、主冷却器７側の冷凍ユニットと連
動するように電気的に接続されている。Therefore, the operating rate of the refrigeration unit on the main cooler 7 side is necessarily higher than the refrigeration unit on the dehumidification cooler 8 side, so the condenser blower 15 is electrically connected to the refrigeration unit on the main cooler 7 side. It is connected to the.
