(57) [Summary] [Purpose] This invention makes it impossible to use the conventional refrigerant CFCs due to environmental problems. Therefore, by using alternative refrigerants, etc. The stable operation of the refrigerator is performed without impairing the temperature. Therefore, the discharge gas temperature should be suppressed, and therefore, the invention is to inject the liquid refrigerant directly into the cylinder of the reciprocating refrigerator. [And] The purpose is to inject liquid cooling soot into the cylinder even in the compression stroke. [Structure] An injection port is provided on the side of the cylinder and is connected to a refrigerant liquid pipe via a linear control injection valve and a solenoid valve.
Description
この考案はレシプロ（往復動）冷凍機装置に関して、低温度域の使用時 における吐出温度の上昇を防止し、冷凍機の仕様範囲を低温度域まで拡大 し、冷凍機油の炭化、劣化を防止することによって安定で持続力ある運転 ができる。 又圧縮行程におけるインジェクションは冷凍機における汲み上げ量の減 少には影響無く冷凍能力は低下しない。 This invention prevents a rise in discharge temperature when using a reciprocating refrigerator device in a low temperature range, expands the specification range of the refrigerator to a low temperature region, and prevents carbonization and deterioration of the refrigerator oil. This enables stable and sustainable driving. Also, the injection in the compression stroke does not affect the reduction of the pumping amount in the refrigerator and the refrigerating capacity does not decrease.
この考案は冷凍装置の冷媒（Ｒ−２２）、新冷媒において、冷凍機の圧 縮行程における吐出温度の上昇を抑え、冷凍機の使用範囲を低温域まで広 げ且つ冷凍機油の劣化等に因る影響を低減し、安定した運転が持続できる 装置を提供するものである。 This invention suppresses the rise of the discharge temperature in the compression stroke of the refrigerator in the refrigerant (R-22) of the refrigeration system and the new refrigerant, expands the operating range of the refrigerator to a low temperature range, and causes deterioration of the refrigerator oil. It is intended to provide a device that reduces the effects of the above and can maintain stable operation.
低温用の冷凍装置（蒸発温度−３５°Ｃ以下）は主にフロンＲ−５０２ の冷媒を使用して冷凍をおこなっている。環境問題によりフロンもも順次 製造停止にもとずき、代替フロンＲ−２２，又新に冷媒が開発途上にある なかで、低温域をカバーする方法として、スクロール冷凍機による方法、 圧縮機の吸入管、又はクランクケースにリキッドインジェクションする方 法が行なわれている。この装置により吐出ガス温度を抑えている。此の為 吸入側に冷却負荷以外の冷媒を流入することによる動力ロス、冷凍能力の 低下をまねき、１ランクアップの冷凍機を必要とする。又吸入管等にイン ジェクションするため、クランクケース内の冷凍機油のフォーミングをま ねき圧縮機の損傷の原因となっていた。 The low-temperature refrigeration system (evaporation temperature -35 ° C or lower) mainly uses the refrigerant of Freon R-502 for refrigeration. Due to environmental problems, due to the sequential stoppage of CFC production, alternative CFC R-22 and new refrigerants are in the process of development. Liquid injection into the suction pipe or crankcase is used. The temperature of the discharged gas is suppressed by this device. For this reason, power loss and refrigerating capacity decrease due to refrigerant other than the cooling load flowing into the suction side, and a refrigerator with one rank higher is required. Further, since the fuel is injected into the suction pipe, etc., forming of refrigerating machine oil in the crankcase causes damage to the compressor.
この考案は以上の点を背景にしてなされたもので従来からのレシプロ冷 凍機のシリンダーに直接且つ圧縮行程においてもリキッドインジェクショ ンする装置を付設した点を特徴とするものである。 The present invention has been made in view of the above points, and is characterized in that a device for liquid injection is attached directly to the cylinder of a conventional reciprocating refrigerator / freezer and in the compression stroke.
以下、この考案の実施例、図面に基づいて説明すれば第１図は冷凍機の レシプロ圧縮機、この圧縮機のシリンダーに穴をあけこれを噴射口（６） とする。これに継ぎ手を加え銅管により第２図の冷媒配管系統図の（１５ ）噴射弁、（１１）電磁弁、を経由して冷媒液管（１６）に接続する。（ １５）の膨張弁の感温筒は吐出温度を感知するよう吐出管に取付ける。ピ ストン（７）は上下運動をし、噴射口（６）はピストンヘッドが（５）の 位置まで下がるまではピストン側面により封鎖されている。（５）の位置 以下から圧縮行程に入って（５）に戻るるまで噴射口（６）は開放され液 冷媒はシリンダー内に噴射を続ける。以上の様にピストン（７）の往復動 行程を繰り返す中でインジェクションが行なわれ、その流量は吐出温度に より制御される。尚電磁弁（１１）は冷凍機の運転中のみ開とする配線に より、従来と変わらぬ制御が可能である。又ピストンの口径により噴射口 （６）に正対する位置にもう一個の噴射口を設ける事でバランスよく運転 できるのである。 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a reciprocating compressor of a refrigerator, a cylinder of which is provided with a hole for use as an injection port (6). A joint is added to this, and a copper pipe is connected to the refrigerant liquid pipe (16) via (15) injection valve and (11) solenoid valve of the refrigerant piping system diagram of FIG. The temperature sensing tube of the expansion valve of (15) is attached to the discharge pipe so as to detect the discharge temperature. The piston (7) moves up and down, and the injection port (6) is blocked by the side surface of the piston until the piston head is lowered to the position (5). The injection port (6) is opened and the liquid refrigerant continues to be injected into the cylinder until the compression stroke starts from the position (5) and the flow returns to (5). Injection is performed while the reciprocating stroke of the piston (7) is repeated as described above, and the flow rate thereof is controlled by the discharge temperature. The solenoid valve (11) can be controlled as before by wiring that is opened only during operation of the refrigerator. Also, by providing another injection port at the position directly facing the injection port (6) depending on the diameter of the piston, it is possible to operate in a well-balanced manner.
従ってこの考案の実施例で示す様にシリンダーに直接インジェクション する装置を備えたものであるから、噴射流入量の大半が圧縮行程でインジ エクションされ（流入タイミングの遅れにより）冷凍能力の低減は極めて 少なく、特に吐出温度を抑える効果は代替冷媒等に充分に発揮でき、安定 した運転が持続出来る。その上軸動力の低減により、エネルギーの節約に なる。 Therefore, as shown in the embodiment of the present invention, since it is equipped with a device for directly injecting into the cylinder, most of the injection inflow amount is injected in the compression stroke (due to the delay of the inflow timing), and the reduction of the refrigeration capacity is extremely small. Especially, the effect of suppressing the discharge temperature can be sufficiently exerted for the alternative refrigerant, etc., and stable operation can be maintained. On top of that, the reduction of shaft power saves energy.
