CN2256078Y - Pipes for separate refrigerating and air-conditioning apparatus - Google Patents

Abstract

The utility model relates to a matched pipe for a separated refrigerating and air-conditioning apparatus, which is a matched pipe for communicating an indoor apparatus and an outdoor apparatus of a separated refrigerating and air-conditioning apparatus, composed of a reflux pipe and a liquid pipe, wherein, a front and a back opposite inserting openings for an inner pipe are arranged on the reflux pipe which is communicated between an evaporator and a compressor. The liquid pipe with a smaller diameter is used for communicating the evaporator and a cooling medium flow controller or the condenser and enters the reflux pipe from the front and the back opposite inserting openings for an inner pipe. Moreover, the liquid pipe is extended through the reflux pipe to be formed into an inner pipe. The utility model has the advantages of easy construction, beautiful appearance, low thermal insulation material cost and saving energy, and reaches the aim of reducing the space taken by the matched pipe for communicating the outdoor apparatus and the indoor apparatus.

Description

The pipe arrangement of separate type freezing air conditioner

The utility model relates to a kind of pipe arrangement of separate type freezing air conditioner, refers to a kind of indoor set of separate type freezing air conditioner and pipe arrangement of off-premises station of being communicated in especially.

At first see also the systematic cyclic graph of a separate type freezing air conditioner shown in Figure 1, its off-premises station A mainly comprises a compressor 1, a condenser 2, a magnetic valve 3 and a cold medium flux controller 4, and indoor set B then comprises a fan motor 5 and an evaporimeter 6; In addition, the circulation pipe arrangement that is communicated with this indoor set B and off-premises station A has two, one is the liquid line 71 that is communicated with evaporimeter 6 from refrigerant flow controller 4 (or self cooling condenser 2), another is the return duct 72 (as shown in Figure 2) that flash-pot 6 is communicated with compressor 1, and liquid line 71 is made of two 711,712 of metal bodys side by side respectively with return duct 72, and be coated with one deck insulation material 712,722 in its caliber, to isolate ambient temperature, the temperature maintenance of the refrigerant in guaranteeing to manage is in a preferable states, yet this kind matched tube structure but has following shortcoming:

When 1, being communicated in two pipe arrangement installings of off-premises station A and indoor set B, must get through two perforation at hard metope W (or on beam), very expend man-hour, add two pipe arrangement diameter differences, need again to be communicated with indoor unit and outdoor unit in mode side by side, institute takes up space very big, when not only causing construction pipeline dig establish difficult, and influence attractive in appearancely, also waste simultaneously indoor space.

2, the considerable insulation material of the essential coating in the pipe arrangement outside causes cost to increase.

Because above-mentioned shortcoming, main purpose of the present utility model is to provide a kind of pipe arrangement of separate type freezing air conditioner, be easy to construct to reach, attractive in appearance, reduce the insulation material cost, reduce that pipe arrangement takes up room and the effective purpose of energy savings.

The pipe arrangement of the separate type freezing air conditioner that provides according to the utility model, it is to be communicated in the indoor set of separate type freezing air conditioner and the pipe arrangement of off-premises station, this pipe arrangement is made up of a return duct and a liquid line, wherein, the return duct that is communicated with evaporimeter and compressor chamber is provided with two opposed interior pipes in front and back and inserts mouth, one diameter is less and be used to be communicated with liquid line between evaporimeter and cold medium flux controller or condenser and manage to insert in two front and back are opposed and mouthful enter, and in this return duct of extend past and form pipe in.

Following conjunction with figs., introduce structure of the present utility model in detail and reach benefit as after.

Fig. 1 is the system schematic of split type air conditioner.

Fig. 2 is the matched tube structure schematic diagram that habit formula split type air conditioner is communicated with indoor set and off-premises station.

Fig. 3 is the utility model matched tube structure schematic diagram.

See also the structural representation (promptly being communicated with the indoor set B of separate type freezing air conditioner and the matched tube structure schematic diagram of off-premises station A) that the utility model shown in Figure 3 is communicated with the pipe arrangement 8 of evaporimeter 6, cold medium flux controller 4 (or condenser 2) and compressor 1, the return duct 81 that one connection evaporimeter 6 and compressor are 1 is the bigger body of a diameter, and this body is provided with two opposed interior pipes in front and back and inserts mouth 812,811; And another liquid line 82 that is communicated in 6 in cold medium flux controller 4 (or condenser 2) and evaporimeter is the less body of a diameter, and make this liquid line 82 insert mouthfuls 812,811 to enter and extend in the body of this return duct 81 by pipe in two of return duct 81, form pipe in, and at the periphery of above-mentioned pipe arrangement 8 coating one deck insulation material 83, so that pipe arrangement 8 is effectively isolated with external environment, refrigerant temperature is not subjected to the influence of environment temperature in guaranteeing to manage.

Improvement by above-mentioned matched tube structure, make when systemic circulation operates, the refrigerant that flow to evaporimeter 6 from refrigerant flow controller 4 (or condenser 2) is a kind of refrigerant of low temperature liquid, and flow to the refrigerant of compressor 1 (in return duct) by evaporimeter 6, because of evaporation is a kind of refrigerant of cryogenic gaseous, wherein this liquid line 82 is because of being installed in the return duct 81, will be because of the heat exchange action that is produced between pipeline, make the refrigerant in this interior pipe can obtain a preferable cooling or a heat insulation effect, improve the heat exchanger effectiveness of evaporimeter 6, the benefit of performance energy savings, simultaneously, and can save this section pipeline heat insulation material cost, and when the installing construction, only need to play a perforation, and do not have past two pipe arrangements and mingle the not aesthetic problem of shuttling back and forth at metope W (or on beam).

In sum, the utility model spy can improve the shortcoming that habit formula block form pipe arrangement consumption takes up space, and effective energy savings has construction of being easy to, attractive in appearance and reduce multiple Practical Benefit such as insulation material cost, really tool progressive.

Claims (1)

1. A kind of pipe arrangement of separate type freezing air conditioner, it is the pipe arrangement that is communicated in separate type refrigerator indoor set and off-premises station, this pipe arrangement is made up of a return duct and a liquid line, it is characterized in that: the return duct that is communicated with evaporimeter and compressor chamber is provided with two opposed interior pipes in front and back and inserts mouth, one diameter is less and be used to be communicated with liquid line between evaporimeter and cold medium flux controller or condenser and manage to insert in two front and back are opposed and mouthful enter, and in this return duct of extend past and form pipe in.
