a kind of external supercooling apparatus, hang over outside this device on off-premises station, include subcooler, electric expansion valve and filter, described subcooler has the first arrival end, first port of export, the second arrival end and second port of export, the first described port of export is connected with liquid pipe outlet, the entrance of described filter is connected with described liquid pipe outlet, the outlet of described filter is connected with the entrance of described electric expansion valve, and the outlet of described electric expansion valve is connected with the second described arrival end.
preferably, the first described arrival end exports with the liquid pipe stop valve of off-premises station and is connected, and the second described port of export fills mouth with the tracheae stop valve of off-premises station and is connected; Described liquid pipe outlet is connected with the pipeline of indoor set.
preferably, the second described port of export is connected with a filled mouth.
preferably, the first described arrival end, second port of export are respectively arranged with sensor.
further preferably, described electric expansion valve, sensor are connected on the mainboard of off-premises station.
preferably, described external supercooling apparatus also includes housing, and the first described arrival end, second port of export and liquid pipe outlet lead to described hull outside.
further preferably, the thickness of described housing and the width of stop valve close.
preferably, described subcooler and plate type heat exchanger.
because technique scheme is used, the utility model compared with prior art has following advantages:
hang over unit side outside the utility model only needs, be connected in series in system by maintenance valve, when not changing unit, provide a kind of scheme of quick increase system degree of supercooling, making Transformation of Unit become very simple and convenient.
Accompanying drawing explanation
accompanying drawing 1 is connected to the schematic diagram between side air-out multi-online indoor machine and off-premises station for the utility model.
wherein: 1, subcooler; 10, the first arrival end; 11, first port of export; 12, the second arrival end; 13, second port of export; 2, electric expansion valve; 3, filter; 4, housing; 5, liquid pipe outlet; 6, mouth is filled; 7, off-premises station; 70, liquid pipe stop valve outlet; 71, tracheae stop valve fills mouth; 8, indoor set; 80, stop valve.
Detailed description of the invention
below in conjunction with drawings and Examples, the utility model is further described:
the external supercooling apparatus of one as shown in Figure 1, hang over outside this device on off-premises station, include housing 4 subcooler 1, electric expansion valve 2 and filter 3, subcooler 1 specifically can be selected as plate type heat exchanger, subcooler 1 has the first arrival end 10, first port of export 11, second arrival end 12 and second port of export 13, concrete connected mode is: first port of export 10 is connected with liquid pipe outlet 5, the entrance of filter 3 is connected with liquid pipe outlet 5, the outlet of filter 3 is connected with the entrance of electric expansion valve 2, the outlet of electric expansion valve 2 is connected with the second arrival end 12, and the first arrival end 10, second port of export 13 and liquid pipe outlet 5 lead to outside housing 4.
in addition, second port of export 12 is connected with a filled mouth 6, and this filled mouth 6 can be used for interior machine and vacuumizes and supplement cold-producing medium.First arrival end 10, second port of export 13 is respectively arranged with sensor.Consider installation and maintenance space after sale, the thickness of the housing 4 of design supercooling apparatus and stop valve similar width, do not add unit to space volume demand.
the concrete step set forth lower external subcooler device and install below:
1, cold-producing medium is reclaimed to off-premises station 7;
2, external supercooling apparatus is installed: the liquid pipe stop valve departing from indoor set 8 pipeline and off-premises station 7 export 70, tracheae stop valve fills connection between mouth 71, the liquid pipe stop valve of off-premises station 7 is exported 70 and is connected; First arrival end 10 of subcooler 1 exports with the liquid pipe stop valve of off-premises station and is connected, and second port of export 13 fills mouth 71 with the tracheae stop valve of off-premises station 7 and is connected; Liquid pipe outlet 5 is connected with the stop valve 80 of indoor set 7 pipeline, is inserted on the mainboard of off-premises station by the connector of electric expansion valve 2 and sensor; Again vacuumize and stop leakage in the roof; System recover;
3, sensor connects and software upgrading;
4, system debug and on-the-spot cleaning.
like this, by the liquid refrigerants after the heat exchange of off-premises station 7 condenser, flow through after liquid pipe stop valve flows to subcooler 1, a part flows to indoor set 8 by newly-increased liquid pipe outlet 5, another part is by after electric expansion valve 2 throttling, refrigerant in cooled cooler 1 main hydraulic pipe, and final suction line of getting back to off-premises station 7 through tracheae stop valve.
the key issue of machine coolant noise in solving, the system that ensures exactly has more than 10 ° stable degree of supercoolings, and now choose the unit that in the present embodiment series (AMS), sales volume is maximum and capacity is maximum and done performance test, data are as follows:
series one (TXM548AMAB):
series two (TXM596ADAA):
above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
