Abstract

The utility model relates to a separable air adjusting device, which is composed of an outdoor machine which has a compressor, and more than one indoor machine which is connected with the outdoor machine by pipelines, wherein, the compressor compresses cooling mediums, and conveys the cooling mediums to each indoor machine for doing heat exchange; expansion chambers and main jet pipes are arranged in the outdoor machine; the quantities of the expansion chambers are as same as the quantities of the indoor machines; the main jet pipes are respectively connected with the compressor and each expansion chamber refluxing; jet pipes are also connected near the connecting positions of all the expansion chambers and the main jet pipes. When any one or a plurality of the outdoor machines are closed, the surplus cooling mediums are automatically sucked in other indoor machines for accelerating the refrigeration of the indoor machines.

Description

Separate air conditioning system

The utility model relates to a kind of conditioner, relates to a kind of by an off-premises station and at least two separate air conditioning systems that indoor set is formed or rather.

Existing separate air conditioning system as the separate cold machine, can comprise the pattern one to one of the corresponding indoor set of an off-premises station and the one-to-many pattern of at least two indoor sets of an off-premises station correspondence from the function branch.With regard to the latter, also can be subdivided into two kinds of patterns, the first is installed a plurality of compressors in single off-premises station corresponding with a plurality of indoor sets respectively, and it two is that only to install a compressor in single off-premises station corresponding with at least two indoor sets.

Conditioner with at least two indoor sets of a compressor correspondence in the single off-premises station, when having a shutdown or a certain the residing room temperature of indoor set to reach preset temperature in each indoor set, traditional practice is to make unnecessary refrigerant be back to compressor.But owing to the single compressed machine designs for satisfying many indoor set needs, the refrigerating capacity that outputs to each indoor set is also fixed, thereby till compressor will remain in operation when the residing room temperature of all indoor sets all reaches preset temperature, in other words, an indoor set closes, suspends and can not make other indoor sets obtain more refrigeration power.

The purpose of this utility model is a kind of separate air conditioning system of design, with at least two indoor sets of at least one compressor supply in the off-premises station, when one or more indoor set is closed or the residing room temperature of indoor set when reaching preset temperature, compressor makes its residing indoor temperature reach preset temperature value rapidly in the refrigerating capacity that stops to increase other indoor sets in its supply refrigerant.

The purpose of this utility model is to realize like this, separate air conditioning system, constitute with the indoor set that is connected with off-premises station by pipeline more than by off-premises station with a compressor, include in the off-premises station and the same number of expanding chamber of indoor set and the main injection pipe that is connected compressor and each expanding chamber respectively, each expanding chamber is connected with each indoor set by pipeline respectively, it is characterized in that:

Also be connected with the backflow playpipe between described each expanding chamber, each playpipe that refluxes stretches in each expanding chamber and is positioned at the side position place that expanding chamber is connected with the main injection pipe.

The described length that stretches into the main injection pipe in the expanding chamber that is shorter in length than that stretches into the interior backflow playpipe of expanding chamber.

When any one or more off-premises station is closed or room temperature of living in when reaching predetermined temperature, its refrigerant more than needed will be sucked into still in the indoor set of work through the backflow playpipe, accelerate its refrigerating speed, the saving energy.

Referring to Fig. 1, Fig. 2, separate air conditioning system of the present utility model comprises an off-premises station 10 and two indoor sets 21,22.Off-premises station 10 contains knockout 11, compressor 12, condenser 13, drier 14, main injection pipe 15,16, expanding chamber 17,18 and control valve V1, V2.Knockout 11 is used to collect the refrigerant after indoor set 21,22 uses.Compressor 12 is used for compression refrigerant after being connected knockout 11.After condenser 13 is connected compressor 12, after drier 14 is connected condenser 13, article two, main injection pipe 15,16 is connected on the drier 14, two expanding chambers 17,18 are connected with two main injection pipes 15,16 respectively, and two control valve V1, V2 then are connected in the connecting line of 21,22 of two expanding chambers 17,18 and indoor sets.

A side that inserts main injection pipe 15,16 at expanding chamber 17,18 is provided with backflow playpipe 31, and the main injection pipe 15,16 that is shorter in length than that backflow playpipe 31 stretches in the expanding chamber 17,18 stretches into the interior length of expanding chamber.When indoor set 21 is closed or its residing indoor temperature when reaching default temperature, control valve V2 closes and stops to indoor set 21 supply refrigerants, expanding chamber 17 interior main injection pipes 15 is the true pressure condition of low pressure because of coolant injection on every side at this moment, near it backflow playpipe 31 is pumped to expanding chamber 17 with the refrigerant that can't send in the expanding chamber 18, promptly when control valve V2 closes, the refrigerant of original supply indoor set 21 can be by auto-pumping to expanding chamber 17, and send indoor set 22 through control valve V1, increase the refrigerating capacity of indoor set 22, make its residing room temperature reach default temperature rapidly, saved the energy.

Referring to Fig. 3, Fig. 4, when with corresponding three indoor sets of the compressor 12 in the off-premises station 21,22,23, main injection pipe 15,16,19 stretches into respectively in the expanding chamber 17,18,20, backflow playpipe 31 is arranged on 17,18 of expanding chambers, backflow playpipe 32 is arranged on 18,20 of expanding chambers, and 33 of backflow playpipes are arranged on 17,20 of expanding chambers.When arbitrary or wantonly two indoor sets are closed or its residing room temperature when reaching default temperature, refrigerant more than needed promptly is pumped to other still in the indoor set of work, to strengthen its refrigerating capacity by backflow playpipe 31 to 33.

By project organization of the present utility model, can be widely used in any separate air conditioning system with many indoor sets such as corresponding four, five of compressors.

Claims (2)

1, a kind of separate air conditioning system, constitute with the indoor set that is connected with off-premises station by pipeline more than by off-premises station with a compressor, include in the off-premises station and the same number of expanding chamber of indoor set and the main injection pipe that is connected compressor and each expanding chamber respectively, each expanding chamber is connected with each indoor set by pipeline respectively, it is characterized in that:

Also be connected with the backflow playpipe between described each expanding chamber, each playpipe that refluxes stretches in each expanding chamber and is positioned at the side position place that expanding chamber is connected with the main injection pipe.
