Abstract
Description
本開示は、空調の技術分野に属し、特に空調室内機・室外機の自己清浄方法に関するものである。 The present disclosure belongs to the technical field of air conditioning, and particularly relates to a method of self-cleaning an air-conditioning indoor unit and an outdoor unit.
空調製品は、蒸発器としてフィンチューブ熱交換器を採用することが一般的である。一定年数使用された場合、室内空気中のほこりは流入空気と共に蒸発器内を流れることで、そのほこり粒子の一部が湿った蒸発器のフィン表面（主に蒸発器の風上面）に貼り付き、空気側汚れが形成されるようになる。この汚れは、必ず蒸発器の熱伝達や圧力降下に悪影響を与え、蒸発器が有する性能の低下を招くとともに、細菌が熱交換器表面で急速に繁殖しやすくなる。細菌が繁殖して集まると、粘り気のある様々な分泌物が生じ、より多くのほこりが蒸発器表面に吸着されてしまうという悪循環に陥る。そのため、空調室内機はその使用中常に清浄を行う必要がある。 Air conditioning products generally employ a fin tube heat exchanger as an evaporator. When used for a certain number of years, dust in the indoor air flows through the evaporator together with the incoming air, and some of the dust particles stick to the fin surface of the wet evaporator (mainly the wind surface of the evaporator). Thus, air-side dirt is formed. This fouling always has an adverse effect on the heat transfer and pressure drop of the evaporator, causing a decrease in the performance of the evaporator, and also makes it easier for bacteria to rapidly grow on the surface of the heat exchanger. As bacteria grow and collect, they produce a variety of sticky secretions, creating a vicious cycle in which more dust is adsorbed to the evaporator surface. Therefore, the air-conditioning indoor unit needs to be constantly cleaned during use.
一方、空調室外機の凝縮器は経年的に室内よりも悪い室外環境に曝されるため、汚れによって詰まりやすくなり、その場合、室外機による空気導入量に影響がおよび、空調の冷房／暖房性能の劣化に繋がっている。そのため、空調室外機の清浄も非常に必要とされている。 On the other hand, the condenser of the air conditioner outdoor unit is exposed to a worse outdoor environment than the indoors over time, and is easily clogged with dirt. In this case, the amount of air introduced by the outdoor unit is affected, and the cooling / heating performance of the air conditioner is affected. Has led to the deterioration of Therefore, it is also very necessary to clean the air conditioner outdoor unit.
従来技術においては、空調室内機及び／又は室外機の清浄方法は多く提案されている。例えば、空調室内機の自己清浄技術に関する中国特許出願ＣＮ１０６８３９２７８Ａ、ＣＮ１０５９２８１３９Ａ、ＣＮ１０７５１４６８３Ａ、ＣＮ１０７６４２８６６Ａ、ＣＮ１０７７６３８７４Ａ、ＣＮ１０７７６３７９６Ａ等、及び、空調室内機・室外機の両者の自己清浄技術に関する中国特許出願ＣＮ１０６５９４９７６Ａ、ＣＮ１０６１５２４１３Ａ、ＣＮ１０６１９６４７６Ａ等がある。しかしながら、これらの技術では、空調室内機と室外機に対する自己清浄機能の要求が十分に満たされていなかった。本発明は、自己清浄を可能とするとともに、省エネルギー且つ高効率のものとなる新たな空調室内機・室外機の自己清浄方法を提案する。 In the prior art, many cleaning methods for air-conditioning indoor units and / or outdoor units have been proposed. For example, Chinese patent applications CN10683278A, CN105988139A, CN107514683A, CN107642866A, CN107763874A, CN107763796A, etc. concerning the self-cleaning technology of the air-conditioning indoor unit, and Chinese patent applications CN1065994976A, CN106152413A, CN1061964476A, etc. concerning the self-cleaning technology of both the air-conditioning indoor unit and the outdoor unit. There is. However, these technologies have not sufficiently satisfied the requirements of the self-cleaning function for the air-conditioning indoor unit and the outdoor unit. The present invention proposes a new self-cleaning method for air-conditioning indoor units / outdoor units that enables self-cleaning and saves energy and has high efficiency.
従来技術の上記問題点に鑑みて、本開示は、空調室内機・室外機の自己清浄方法を提供することを目的の一つとする。この方法によれば、空調室内機と室外機の自己清浄が可能になり、長期間の使用につれて室内機の蒸発器やエアダクト及び室外機の凝縮器にほこりが堆積するという問題が解決され、空調の冷房／暖房性能への影響や利用者の健康被害が回避されるようになる。 In view of the above problems of the related art, an object of the present disclosure is to provide a method for self-cleaning an air-conditioning indoor unit and an outdoor unit. According to this method, self-cleaning of the air-conditioning indoor unit and the outdoor unit becomes possible, and the problem that dust accumulates on the evaporator and air duct of the indoor unit and the condenser of the outdoor unit over a long period of use is solved, The effect on the cooling / heating performance and the health damage of the user can be avoided.
