Problems solved by technology

[0014] (c) In addition, if the accuracy of processing and processing dimensions of the extension pipe is deteriorated, sufficient sealing performance cannot be ensured, and in the worst case, the extension pipe cannot pass through the hole, and the processing of the extension pipe itself The case of rework
[0015] In other words, in order to ensure the airtightness of the hole portion of the sealed box, the hole itself can be formed with high dimensional accuracy, although it can be handled by the manufacturer (manufacturer) of the air conditioner, but on the other hand, it is desired to form the hole itself in the same way as the hole portion. The high precision corresponding to the high dimensional accuracy itself may not be easy for the on-site installers to process the extension piping, which will make the workability worse

Abstract

The interior of a housing (110) forming an indoor unit (101) of an air-conditioning device (100) is partitioned in the left-right direction by an air passage partition plate (20). An air passage chamber (21) accommodating an indoor blowing fan (7f) and an indoor heat exchanger (7) is formed on a housing lateral surface (117) side, and by means of a partition plate (30) in which through-holes (31a, 31b) are formed a housing lateral surface (118) side is further partitioned in the up / down direction, thereby forming on the upper side a pipe connection chamber (22), in which a portion of extension pipes (10a, 10b), flare connectors (15a, 15b), and indoor pipes (9a, 9b) are accommodated, and forming on the lower side a pipe extraction chamber (23), in which the extension pipes (10a, 10b) are routed. Insulation (19a, 19b) fills a gap between the respective outer circumferences of the extension pipes (10a, 10b) and the inner circumferences of the through-holes (31a, 31b).

Description

technical field [0001] The present invention relates to a refrigerating cycle device, in particular to a refrigerating cycle device using a refrigerant with a low global warming coefficient to perform a refrigerating cycle. Background technique [0002] Conventionally, non-flammable "HFC refrigerants" such as R410A have been used as refrigerants in a refrigeration cycle performed by an air conditioner which is one of refrigeration cycle devices. Unlike conventional "HCFC refrigerants" such as R22, this R410A has a zero ozone layer depletion coefficient (hereinafter referred to as "ODP") and does not destroy the ozone layer, but has a global warming coefficient (hereinafter referred to as "GWP") higher nature. [0003] Therefore, as a step to prevent global warming, studies have been advanced to switch from high-GWP HFC refrigerants such as R410A to low-GWP refrigerants. [0004] As a candidate for the above-mentioned low-GWP refrigerant, there is R290 (C 3 h 8 : propane)...
