Abstract
Description
本発明は、濾過構造を備えた二回絞り二方膨張弁を提供するものであり、それは、蒸気圧縮式熱ポンプ型冷凍システムの絞り(スロットル)技術領域に属し、特に、熱ポンプ型空気調節装置の冷凍システムに適用する絞り部品である。 The present invention provides a double-throttle two-way expansion valve with a filtration structure, which belongs to the throttling technology area of a vapor compression heat pump refrigeration system, and in particular, heat pump air conditioning It is a throttle part applied to the refrigeration system of the apparatus.
公知の熱ポンプ型空気調節装置冷凍システムの絞り部分の二方膨張弁は、ダイアフラムで温度を感知し弁口絞り通路断面を自動調節することにより、一回だけ絞るものであり、絞り前と絞り後の通路断面は、どちらも、弁口絞り通路の最大断面より大きく、その左右液体連接管及び弁体内はどちらも、濾過構造を持たないものである。冷凍過程と製熱過程において必要とされる流量は異なり、ダイアフラムが温度感知した時の弁口絞り通路断面と要求する弁口通路断面が合わない場合、冷凍システム中に残された混合物が膨張弁の調節機構に入り込み、引っ掛かりやつまり現象を引き起こし、冷凍システムの効果は低下して正常運転が不可能となる。 The two-way expansion valve in the throttle part of a known heat pump type air conditioner refrigeration system is a diaphragm that senses the temperature and automatically adjusts the cross-section of the valve mouth throttle passage. Both of the subsequent passage cross-sections are larger than the maximum cross-section of the valve orifice throttle passage, and neither the right or left liquid connecting pipe nor the valve body has a filtration structure. The flow rate required for the refrigeration process and the heat production process is different, and if the diaphragm of the valve orifice passage when the diaphragm senses the temperature does not match the required orifice passage cross section, the mixture left in the refrigeration system will expand into the expansion valve. The control mechanism of the refrigeration system enters and causes a catch or phenomenon, and the effect of the refrigeration system is reduced to make normal operation impossible.
解決しようとする問題点は、公知の熱ポンプ型空気調節装置冷凍システムの絞り部分の二方膨張弁は、一回だけの絞りであり、濾過構造を持たず、冷凍システム中に残された混合物が膨張弁の調節機構に入り込んでつまりを引き起こす点である。 The problem to be solved is that the two-way expansion valve in the throttle portion of the known heat pump type air conditioner refrigeration system is a one-time throttle, does not have a filtration structure, and the mixture left in the refrigeration system This is the point that enters the adjustment mechanism of the expansion valve and causes clogging.
上述課題の解決する本発明の主目的は、合理的な設計、簡単な構造を持ち、熱ポンプ型空気調節装置の冷凍システムにおいて、冷凍過程と製熱過程が必要とする異なる流量を満足させ、冷凍システムの正常運転を保証する、濾過構造を備えた二回絞り二方膨張弁を提供することにある。 The main object of the present invention to solve the above problems is to have a rational design, simple structure, satisfy different flow rates required for the refrigeration process and the heat production process in the refrigeration system of the heat pump type air conditioner, An object of the present invention is to provide a double-throttle two-way expansion valve with a filtration structure that guarantees normal operation of a refrigeration system.

And a right connecting pipe, and a throttle hole is provided on the passage before (or after) the throttle opening (rear) or after (the front) passage of the valve opening, and the passage section of the throttle hole is smaller than the maximum section of the valve throttle passage.

本発明の濾過構造を備えた二回絞り二方膨張弁に関する第一実施例を図1に示す。 FIG. 1 shows a first embodiment relating to a double-throttle two-way expansion valve equipped with the filtration structure of the present invention.
絞り孔8は、弁体1との直接加工により形成され、絞り孔8の通路断面は、弁口絞り通路6の最大断面より小さく、濾過ネット2は、弁体1両端、及び左液体連接管9、右液体連接管10間にそれぞれ配置する。その作業工程は、図5及び図1に示すとおりである。 The throttle hole 8 is formed by direct machining with the valve body 1, the passage cross section of the throttle hole 8 is smaller than the maximum cross section of the valve mouth throttle passage 6, and the filtration net 2 includes both ends of the valve body 1 and the left liquid connecting pipe. 9. Arrange between the right liquid connecting pipe 10 and the right liquid connecting pipe 10, respectively. The working process is as shown in FIG. 5 and FIG.
もし、熱ポンプ型空気調節装置冷凍システムが冷凍過程であるなら、気体冷凍剤は、圧縮機41によって圧縮されて高圧高温気体冷凍剤となり、四方電磁弁42を経て室外熱交換器43に入り冷却凝結され高圧液体冷凍剤となり、高圧液体冷凍剤は、濾過構造を備えた二回絞り二方膨張弁44の左液体連接管9から濾過構造を備えた二回絞り二方膨張弁44に入り、弁口絞り前(後)通路4、5を経て、ダイアフラムによって温度感知され、通路断面を自動調節した弁口絞り通路6に入り、第一回目の絞りを施す。高圧液体冷凍剤は、第一回目の絞り後、低圧低温気体液体混合冷凍剤となり、弁口絞り後通路7を経て、絞り孔8に入り、第二回目の絞りが行われる。低圧低温気体液体混合冷凍剤は、第二回目の絞り後、圧力と温度が更に低くなり、また、気体冷凍剤の比率が更に高い気体液体混合冷凍剤となる。右液体連接管10を経て、進入室内熱交換器45に入り、熱吸収し蒸発して低圧気体冷凍剤となり、四方電磁弁42を経て、圧縮機41に戻り冷凍過程のサイクルを終了させる。 If the heat pump type air conditioner refrigeration system is in the refrigeration process, the gas refrigerant is compressed by the compressor 41 to become a high-pressure and high-temperature gas refrigerant, enters the outdoor heat exchanger 43 through the four-way solenoid valve 42, and is cooled. When condensed, it becomes a high-pressure liquid freezing agent, and the high-pressure liquid freezing agent enters the double-throttle two-way expansion valve 44 with the filtration structure from the left liquid connecting pipe 9 of the double-throttle two-way expansion valve 44 with the filtration structure, Through the passages 4 and 5 before the throttle opening (rear), the temperature is sensed by the diaphragm and enters the throttle opening passage 6 in which the passage section is automatically adjusted, and the first throttle is applied. The high-pressure liquid cryogen becomes a low-pressure low-temperature gas-liquid mixed refrigerant after the first throttling, enters the throttling hole 8 via the post-throttle passage 7, and the second throttling is performed. The low-pressure low-temperature gas-liquid mixed refrigerant becomes a gas-liquid mixed refrigerant with a lower pressure and temperature and a higher ratio of the gas refrigerant after the second squeezing. Through the right liquid connecting pipe 10, it enters the heat exchanger 45 in the entrance room, absorbs heat and evaporates to become a low-pressure gas refrigerant, returns to the compressor 41 through the four-way solenoid valve 42, and ends the cycle of the refrigeration process.
もし、熱ポンプ型空気調節装置が製熱過程である場合は、気体冷凍剤は、圧縮機41によって圧縮されて高圧高温気体冷凍剤となり、四方電磁弁42を経て室内熱交換器45に進入して冷凍凝結されて高圧液体冷凍剤となり、高圧液体冷凍剤は、濾過構造を備えた二回絞り二方膨張弁44の右液体連接管10から、濾過構造を備えた二回絞り二方膨張弁44に進入、絞り孔8によって第一回目の絞りが行われ、また、弁口絞り前通路7を経て弁口絞り通路6に入り第二回目の絞りが行われる。第二回目の絞り後の気体混合冷凍剤によって弁口絞り後通路4、5及び左液体連接管9を通過し室外熱交換器43に進入、熱を吸収、蒸発し、低圧気体冷凍剤となり、四方電磁弁42によって圧縮機41に戻されて製熱サイクルを完成する。 If the heat pump type air conditioner is in the process of producing heat, the gas refrigerant is compressed by the compressor 41 to become a high-pressure and high-temperature gas refrigerant, and enters the indoor heat exchanger 45 through the four-way solenoid valve 42. The high-pressure liquid cryogen is condensed from the right liquid connecting pipe 10 of the double-throttle two-way expansion valve 44 with the filtration structure, and the double-throttle two-way expansion valve with the filtration structure. 44, the first throttling is performed by the throttling hole 8, and the second throttling is performed through the valve throttling pre-passage 7 and the valve throttling passage 6. After the second throttling, the gas mixed freezing agent passes through the after-throttle passages 4 and 5 and the left liquid connecting pipe 9 and enters the outdoor heat exchanger 43, absorbs heat, evaporates, and becomes a low-pressure gaseous freezing agent. The four-way solenoid valve 42 returns to the compressor 41 to complete the heat production cycle.
冷凍過程である場合、通路断面を自動調節する弁口絞り通路6は第一回目の絞りを行い、絞り孔8は第二回目の絞りを行う。また、製熱過程である場合、絞り孔8は第一回目の絞りとなり、通路断面を自動調節する弁口絞り通路6では第二回目の絞りが行われる。熱ポンプ型空気調節装置において、正、逆方向の作業を行うことにより、冷凍過程と製熱過程で必要な異なる流量を満足することができ、同時に、第二回目の絞りは、膨張弁が普遍的に存在させている波動と振動を根本的に克服し、冷凍システムの効率を高めるものである。弁体1と左液体連接管9、右液体連接管10間には、どちらも濾過ネット2を設け、正方向もしくは逆方向の作業に関わらず、どちらも、冷凍システム中に残った混雑物が膨張弁の調節機構に詰まるのを阻止する外、冷凍システムの正常運転を保証する。 In the refrigeration process, the valve throttle passage 6 that automatically adjusts the cross section of the passage performs the first throttling, and the throttling hole 8 performs the second throttling. In the heat production process, the throttle hole 8 is the first throttle, and the second throttle is performed in the valve throttle passage 6 that automatically adjusts the passage cross section. In the heat pump type air conditioner, by working in the forward and reverse directions, different flow rates required for the refrigeration process and the heat production process can be satisfied. At the same time, the expansion valve is universal for the second throttle. It fundamentally overcomes the existing waves and vibrations and increases the efficiency of the refrigeration system. A filter net 2 is provided between the valve body 1 and the left liquid connecting pipe 9 and the right liquid connecting pipe 10, both of which are left in the refrigeration system regardless of whether the work is in the forward or reverse direction. In addition to preventing the adjustment mechanism of the expansion valve from clogging, it ensures normal operation of the refrigeration system.
