【発明の詳細な説明】
技術分野：本発明は二次冷媒液（以下ブライン）式冷凍
方式の冷凍設備での空気冷却器のデフロスト方法に関す
る。DETAILED DESCRIPTION OF THE INVENTION Technical Field: The present invention relates to a defrosting method for an air cooler in a secondary refrigerant liquid (hereinafter referred to as brine) type refrigeration equipment.
従来技術、その問題点：従来は空気冷却器の一環プライ
ンを冷凍時には〜３２〜−３５Ｃとしていたものをデフ
ロスト時には＋５〜１０Ｃに加熱して用い、デフロスト
完了後は再び−３２〜−一３５Ｃに戻すという方法をと
っていた。これではブラインを加熱、冷却するため熱損
失が多い。Conventional technology and its problems: Conventionally, the air cooler's continuous pline was heated to ~32 to -35C during freezing, but was heated to +5 to +10C during defrosting, and then heated to -32 to -35C again after defrosting was completed. The method was to return it. This causes a lot of heat loss as the brine is heated and cooled.
問題解決の手段：それで本発明ではブラインの加熱冷却
しなくてもずむよう冷凍用ブラインとデフロスト用のブ
ラインとを個別にし、それらの貯蔵タンクを夫々おいて
それらブラインの作用時以外はこれらのタンクに貯蔵し
ておくこととした。Means for solving the problem: Therefore, in the present invention, the freezing brine and the defrosting brine are separated so that the brine does not need to be heated or cooled, and a storage tank for each is provided, so that these tanks are not used except when the brine is in operation. I decided to store it in.
この貯蔵タンクは冷、熱別個に置いてもよく、亦一つの
タンク内に移動仕切りを置いてこれに冷・熱タンクを兼
ねさせてもよい。This storage tank may be placed separately for cold and hot storage tanks, or a movable partition may be placed in one tank to serve as a cold and hot storage tank.
実施例：ここでは一つのタンク内に移動仕切りをおいて
これを冷熱向ブライン貯蔵用に兼用する場合（１タンク
方式）について説明する。Embodiment: Here, a case will be described in which a movable partition is provided in one tank and used for storing brine for both cooling and heating (one tank system).
冷熱別個にタンクをおく２タンク方式でもブライン制御
はこの場合と全く同様である。Brine control is exactly the same in a two-tank system with separate tanks for cold and hot water.
第１図は本方法におけるブラインの系統図で。Figure 1 is a systematic diagram of the brine used in this method.
鎖線内が本り法のために従来系統に付加された部分であ
る（冷棟機は省略）９図で１は空気冷却器。The part inside the chain line is the part added to the conventional system for this method (the cold ridge unit is omitted).In Figure 9, 1 is the air cooler.

５はバルブである。2 is a brine heater, 3 is a brine pump for defrosting, 4 is a brine storage tank, 4a is a movable partition in the tank, 4b is a hot brine storage compartment in the tank, 4c is a cold brine compartment, 10.11. 12.13, 14.1
5 is a valve.
１）デフロスト開始時：デフロストの開始時にはタンク
４では移動仕切り４ａが図で最も右に寄り、４ｂ区画は
すなわちタンク４仝体が然ブラインで満たされている。1) At the start of defrost: At the start of defrost, the movable partition 4a of the tank 4 is closest to the right in the figure, and the section 4b, that is, the entire body of the tank 4, is filled with brine.
この状態でバルブ１０〜１５を所要の通過方向に置いて
熱ブラインを４ｂ区画からブライン加熱器２を通じて空
気冷却器１に送り込む。空気冷却器１では熱ブラインが
送り込まれただけ冷ブラインが排除され、冷ブラインは
タンク４の４ａ区画に仕切り４ａを移動させながら蓄積
される。In this state, the valves 10-15 are placed in the required passage direction to send the hot brine from section 4b through the brine heater 2 to the air cooler 1. In the air cooler 1, the cold brine is removed as much as the hot brine is sent, and the cold brine is accumulated in the 4a section of the tank 4 while moving the partition 4a.
２）デフロスト時：空気冷却器１が熱ブラインで満たさ
れた状態でタンク４では仕切り４ａが図で最も３１．：
寄り４ａＩ％画はつまりタンク４仝休は冷ブラインで満
たされる。この状態でブライン貯蔵タンク４をラインか
ら切離し、ポンプ３−〉ブラ、イン加熱器２−〉空気冷
却器１−〉ポンプ３によリゾフロストを行う。2) During defrosting: When the air cooler 1 is filled with thermal brine, the partition 4a in the tank 4 is at the most 31. :
The 4aI percentage point means that tank 4 is filled with cold brine. In this state, the brine storage tank 4 is disconnected from the line, and resofrost is performed using the pump 3->brush, in-heater 2->air cooler 1->pump 3.
３）デフロスト終了時：デフロスト終了すればブライン
加熱器２を短絡しタンク４をラインに入れ、ライン中の
熱ブラインを冷ブラインに入れ替え、タンク４が熱ブラ
インで満たされた状態でタンク４をラインから切離し、
熱ブラインはタンク４に貯蔵されてラインは冷凍サイク
ルに入る。3) At the end of defrosting: When defrosting is completed, short-circuit brine heater 2, put tank 4 into the line, replace the hot brine in the line with cold brine, and put tank 4 into the line with tank 4 filled with hot brine. separated from
Thermal brine is stored in tank 4 and the line enters the refrigeration cycle.
効果：このように本発明では冷熱２種のブラインを使い
分【ブることにより従来のような一つの１ラインを加熱
冷却する熱損失が避けられることとなる。Effect: In this way, in the present invention, by using two types of cold and hot brine, the conventional heat loss caused by heating and cooling one line can be avoided.
また１貯蔵タンクを用いる方法ではタンクは冷熱の何れ
かまたは双方のブラインにより常に充満されていること
になるのでブラインが空気に触れることがなくその酸化
を防ぎつると共に２タンク方法よりタンク容積を小さく
することができる。、In addition, in the method using one storage tank, the tank is always filled with either cold or hot brine, so the brine does not come into contact with air, preventing its oxidation, and the tank volume is smaller than in the two-tank method. can do. ,
