Summary of the invention
Main purpose of the present utility model is to provide a kind of throttling arrangement of indoor set, is intended to effectively solve in prior art when refrigerant evaporation, and gaseous coolant washes away the technical problem that electric expansion valve causes larger noise.
In order to realize the utility model purpose, the utility model provides a kind of throttling arrangement of indoor set, described indoor set is provided with electric expansion valve, described throttling arrangement comprises refrigerant heat exchanger and first throttle spare, described refrigerant heat exchanger is arranged between the condenser and electric expansion valve of off-premises station, described first throttle spare is connected with described refrigerant heat exchanger by skirt, and its outlet is connected with the refrigerant entrance of electric expansion valve.
Preferably, also be provided with check valve between described indoor set and described refrigerant heat exchanger.
Preferably, described first throttle spare is electric expansion valve.
Preferably, described refrigerant heat exchanger is bushing type or board-like.
The utility model also provides a kind of multi-connected machine system, comprises compressor, off-premises station and indoor set, and it also comprises the throttling arrangement of indoor set.Described indoor set is provided with electric expansion valve, described throttling arrangement comprises refrigerant heat exchanger and first throttle spare, described refrigerant heat exchanger is arranged between the condenser and electric expansion valve of off-premises station, described first throttle spare is connected with described refrigerant heat exchanger by skirt, and its outlet is connected with the refrigerant entrance of electric expansion valve.
The utility model can will be evaporated by the coolant distribution of compressor output by the refrigerant heat exchanger in throttling arrangement and first throttle spare, carry out heat exchange with the main refrigerant of condensator outlet, make main refrigerant in refrigerant heat exchanger in heat release be cooled and obtain desirable degree of supercooling, thereby improve the stability of complete machine operation.Due to when refrigeration refrigerant shunted, therefore can reduce the gas that it produces when evaporation, thereby reduce gas to the washing away of indoor set electric expansion valve, reduce noise.
Description of drawings
Fig. 1 is the structural representation of the throttling arrangement of indoor set in the utility model one preferred embodiment.
The realization of the utility model purpose, functional characteristics and advantage are described further with reference to accompanying drawing in connection with embodiment.
The specific embodiment
Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
The utility model provides a kind of throttling arrangement of indoor set, with reference to shown in Figure 1, be provided with electric expansion valve 9 between indoor set 10 and off-premises station 4, the throttling arrangement of indoor set comprises refrigerant heat exchanger 7 and first throttle spare 8, described refrigerant heat exchanger 7 is arranged between off-premises station 4 and electric expansion valve 9, described first throttle spare 8 is connected with described refrigerant heat exchanger 7 by skirt, and the outlet of described first throttle spare 8 is connected with the refrigerant entrance of electric expansion valve 9.
In the utility model embodiment, the refrigerant that flows out from off-premises station 4 condensator outlets is through after refrigerant heat exchanger 7, and a part enters first throttle spare 8 reducing pressure by regulating flows, enters refrigerant heat exchanger 7 by skirt, carries out heat exchange with the main refrigerant of off-premises station 4 condensator outlets.Make winner's refrigerant in refrigerant heat exchanger 7 in heat release be cooled and obtain desirable degree of supercooling.The utility model can be controlled the flow of bypass refrigerant as required, thereby reaches the purpose of controlling degree of supercooling, has effectively solved the phenomenon of refrigerant shwoot before entering evaporimeter, and the reduction refrigerant washes away electric expansion valve 9, thereby reduces noise; And after obtaining certain degree of superheat after bypass refrigerant heat absorption evaporation, enter into the evaporimeter of indoor set 10, improved to a certain extent the degree of superheat of system, prevented the band hydraulic compression of compressor, improve system's reliability of operation.
With reference to shown in Figure 1, in the throttling arrangement embodiment of the utility model indoor set, except above-mentioned refrigerant heat exchanger 7, first throttle spare 8, also comprise the check valve 11 that is arranged between indoor set 10 and described refrigerant heat exchanger 7, flow in order to control refrigerant, the utility model throttling arrangement can only be worked when cooling system.As shown in Figure 1, in the utility model embodiment when refrigeration refrigerant flow to as follows: the gases at high pressure that compressor 1 is discharged after oil eliminator 2, cross valve 3, enter the condenser of off-premises station 4, then enter into indoor set 10 through off-premises station throttle part 5.Before evaporimeter due to indoor set 10, throttling arrangement is installed, refrigerant is got back to off-premises station 4 after being evaporated in the evaporimeter of indoor set 10, and the low-pressure liquid storing tank 13 of flowing through is got back to compressor 1, completes a circulation.
In the utility model embodiment, first throttle spare 8 is preferably electric expansion valve.The present embodiment can be controlled the flow of bypass refrigerant by the aperture of regulating electric expansion valve, reach the purpose of controlling degree of supercooling.
