本考案は、空気調和設備のドレーン配管を簡易

関する。[Detailed Description of the Invention] The present invention relates to an improved piping structure that allows drain piping of air conditioning equipment to be cleaned easily and reliably.
空気調和機のドレーン配管はこれを放置してお

パイプの腐食等のドレーン配管の損傷が不可避で
あり、やつかいな作業となつていた。 If the drain piping of an air conditioner is left unattended, it will become clogged with dirt, water scale, etc., leading to water leaks and bad odors. Conventionally, in such cases, countermeasures have been taken, such as cutting the drain pipe and mechanically removing the clogged object, or injecting a chemical solution into the drain pipe to dissolve the foreign object. However, these measures are measures taken after an accident occurs and are not preventive measures. Moreover, damage to the drain piping, such as pipe cutting or corrosion of the pipe due to the chemical solution, is inevitable, making the work difficult.
本考案は、このような空気調和機のドレーン配

である。 The present invention relates to a piping structure that prevents clogging of the drain piping of such an air conditioner.

７に制水弁６を取付ける。 To explain this according to the embodiments in the drawings, the first
In the figure, 1 is a water heat source heat pump unit or fan coil unit located at various locations in the building, 2 is a water side heat exchanger installed in each unit, 3 is a heat source water outgoing pipe, and 4 is a heat source water return pipe. , 5 is a drain pipe, and in the present invention, the heat source water outgoing pipe 3 leading to the water side heat exchanger 2 of each unit 1 and the drain pipe 5 are connected by a connecting pipe 7 with a water control valve 6 interposed. It is characterized by More specifically, in the drain piping of a group of units on a certain floor, a part of the drain piping on the uppermost side is connected to a nearby heat source water outgoing pipe by a connecting pipe 7, and a water control valve is connected to this connecting pipe 7. Install 6.
これにより、制水弁６を一定の開度まで開く

清掃が行ない得る。 Thereby, when the water control valve 6 is opened to a certain opening degree, the heat source water in the heat source water outgoing pipe 3 flows into the drain pipe 5, and the deposits in the drain pipe are washed away, thereby cleaning the inside of the pipe. Therefore, the drain pipe 5 can be cleaned by simply opening the water control valve 6 at an opening that prevents backflow from the drain pan in the unit immediately before or after the air conditioner starts cooling operation. .

高いものである。 In this way, the present invention provides an air conditioning system in which a plurality of water heat source heat pump units or fan coil units 1 are arranged in a building. Since the heat source water outgoing pipe leading to the exchanger is connected with the connecting pipe 7 with the water control valve 6 installed, just by opening the water control valve 6 to a certain opening immediately before or after cooling operation, Various troubles caused by conventional clogging accidents can be prevented. Moreover, with this invention, it is only necessary to leave the existing piping as it is and attach a connecting pipe with a water control valve to it, so the equipment cost is extremely light, and the existing equipment can also be used during the interim period. Since it can be easily installed, it is extremely practical as a preventive measure against water leakage from drains, which has caused serious problems in the past.
