Poor refrigerating efficiency.
How to improve the structure of floride-free direct current varied-frequency air conditioner, can be when worst hot case the compressor operating high-frequency, refrigerant circulation is big; Reduce condenser duty; Improve the evaporimeter utilization rate, promote the indoor set refrigeration greatly, this is the present problem demanding prompt solution in present technique field.
Summary of the invention
The utility model is for solving the problem that prior art exists; A kind of floride-free direct current varied-frequency air conditioner is provided; Can be when worst hot case the compressor operating high-frequency; Refrigerant circulation is big, reduces condenser duty, improves the evaporimeter utilization rate; Promote the indoor set refrigeration greatly; The purpose of the utility model realizes through following technical scheme: a kind of floride-free direct current varied-frequency air conditioner, comprise four-way change-over valve, triple valve, two logical stop valves, three-way cut-off valve, device for drying and filtering, capillary, indoor machine evaporation and outdoor condenser on compressor, fluid reservoir, pipeline, the pipeline, and it is characterized in that the import of described triple valve is connected with exhaust outlet of compressor; First outlet of said triple valve is connected to described four-way change-over valve through pipeline, and second outlet of said triple valve connects on the feed liquor pipeline that an one-way throttle valve is connected to indoor machine evaporation through pipeline.
Improvement to technique scheme: other three interfaces of described four-way change-over valve are connected with fluid reservoir, condenser and evaporator outlet end respectively through three pipelines, are connected said three-way cut-off valve on the pipeline of connection four-way change-over valve and evaporator outlet end.
Further improvement to technique scheme: described condenser is connected to and sets gradually said device for drying and filtering, capillary, device for drying and filtering, two logical stop valves on the pipeline of indoor machine evaporation.
Further improvement to technique scheme: described compressor is a DC frequency-changeable compressor.
The utility model compared with prior art has many advantages and good effect:
1, the utility model compressor operating high-frequency when worst hot case, refrigerant circulation is big, reduces condenser duty, improves the evaporimeter utilization rate, and refrigeration system is more stable, promotes the indoor set refrigeration greatly;
2, the one-way throttle valve of the utility model employing plays the throttling step-down.Design has many good qualities in indoor set as throttle mechanism to use this device: concentrating of structure, shortened the flow path of refrigerant, and avoided refrigerant at the noise that vibrations caused that flow in capillary tube produces, help reducing the noise of air-conditioning system; The metal spool structure helps heat transmission, eliminates the stifled phenomenon of ice, need not use device for drying and filtering.
Description of drawings
Fig. 1 is the johning knot composition of a kind of floride-free direct current varied-frequency air conditioner embodiment of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Referring to Fig. 1; The embodiment of a kind of floride-free direct current varied-frequency air conditioner of the utility model; Comprise four-way change-over valve 5, triple valve 4, three-way cut-off valve 3, two logical stop valves 8, device for drying and filtering 9,11, capillary 10, indoor machine evaporation 1 and outdoor condenser 7 on compressor 6, fluid reservoir, pipeline, the pipeline; The import of described triple valve 4 is connected with compressor 6 exhaust outlets; The first outlet 4-1 of said triple valve 4 is connected to described four-way change-over valve 5 through pipeline, and the second outlet 4-2 of said triple valve 4 connects on the feed liquor pipeline that an one-way throttle valve 2 is connected to indoor machine evaporation 1 through pipeline.Other three interfaces of described four-way change-over valve 5 are connected with fluid reservoir, condenser 7 and evaporimeter 1 port of export respectively through three pipelines.Be connected described three-way cut-off valve 3 on the pipeline of the connection four-way change-over valve 5 and evaporimeter 1 port of export.Described condenser 7 is connected to and is connected in series device for drying and filtering 11, capillary 10, device for drying and filtering 9, two logical stop valves 8 on the pipeline of indoor machine evaporation 1 successively.Above-mentioned compressor 6 is a DC frequency-changeable compressor.
The method of operation of a kind of floride-free direct current varied-frequency air conditioner of the utility model is following:
The one-way throttle valve 2 that between compressor 6 exhaust outlets and indoor machine evaporation 1 feed liquor pipeline, is connected, is judged through automatically controlled outer shroud temperature sensor detected temperatures when outdoor environment is worst hot case as the bypass throttle mechanism, gets into the load removal refrigeration mode.Triple valve 4 second outlet 4-2 open; The HTHP refrigerant of discharging from compressor 6 exhaust outlets flows out from 4 fens two-way of triple valve; Flow out refrigerant from triple valve 4 first outlet 4-1 and carry out cooling condensation through four-way change-over valve 5 entering condensers 7; The liquid refrigerants that flows out cryogenic high pressure from condenser 7 gets into capillary 10 through device for drying and filtering 11 backs and carries out the throttling step-down, and the gas-liquid two-phase refrigerant that flows out low-temp low-pressure from capillary 10 flows into indoor machine evaporation 1 through two logical stop valves 8 with pipeline after flowing through device for drying and filtering 9; Flowing out refrigerant entering one-way throttle valve 2 from triple valve 4 second outlet 4-2 carries out flowing into indoor machine evaporation 1 by the road after the throttling step-down; Flow out refrigerants and flow out refrigerants from triple valve 4 second outlet 4-2 and converge and get into evaporimeter 1 and evaporate heat absorption from triple valve 4 first outlet 4-1; The gaseous coolant that flows out low-temp low-pressure from evaporimeter 1 flows into four-way change-over valve 5 through pipeline and three-way cut-off valve 3; Flowing out refrigerant from four-way change-over valve 5 compresses through fluid reservoir inflow compressor 6 cylinder bodies; Refrigerant is compressed into the gas of HTHP and discharges through compressor 6 exhaust outlets, carries out circularly cooling so repeatedly.
