Description
Technical field
The present invention relates to field of air conditioning, when being specifically a kind of gas-liquid separator and air conditioner refrigerating of air-conditioning, utilize this gas-liquid separator to carry out the method for noise reduction to the indoor set of air-conditioning.
Background technology
The gas-liquid separator of the air-conditioning of prior art is arranged on off-premises station, is specifically the entrance front end of compressor, and its effect realizes gas-liquid separator, stored by liquid refrigerants, guarantees that the refrigerant entering compressor is all gas, prevent liquid hammer compressor.And during air-conditioner set refrigerating operaton, desirable situation be refrigerant after outdoor heat exchanger condensation, whole liquefy refrigerant enter indoor set indoor heat exchanger evaporation.But in actual motion, often there is various working, as higher in outdoor environment temperature or blower fan wind shelves are less, cause the quantity not sufficient that refrigerant liquefies in outdoor heat exchanger, like this, just there is gas-liquid two-phase state when refrigerant enters into indoor set, and gas-liquid two-phase refrigerant can produce abnormal sound and noise when indoor set carries out throttling, interference user is had a rest, and causes poor Consumer's Experience.
Summary of the invention
The technical problem that the present invention will solve is, provides a kind of gas-liquid separator of air-conditioning liquid refrigerants can discharged by gaseous coolant storage.
A technical solution of the present invention provides a kind of gas-liquid separator of air-conditioning, and it comprises tubular shell, an inlet pipe flowed into for gas-liquid two-phase refrigerant and one are flowed out for liquid refrigerants goes out pipe, and an end plate is respectively established at tubular shell two ends; Inlet pipe inserts the inner chamber of tubular shell through an end plate, the port of export of inlet pipe and the inner space of tubular shell and the port of export of inlet pipe upwarp, go out pipe inserts tubular shell inner chamber through another end plate, go out the arrival end of pipe and the inner space of tubular shell and the arrival end going out pipe is downward elbow, also be provided with one piece in the inner chamber of tubular shell for blocking from the baffle plate of the refrigerant of inlet pipe port of export ejection, the cylinder inwall of baffle plate upper end and tubular shell is fixed.
Another technical problem that the present invention will solve is, provides a kind of gas-liquid two-phase refrigerant of effectively avoiding to utilize gas-liquid separator to carry out the method for noise reduction to the indoor set of air-conditioning when the refrigeration of indoor set throttling.
Technical solution of the present invention is, provide during a kind of refrigeration and utilize gas-liquid separator to carry out the method for noise reduction to the indoor set of air-conditioning, it comprises the following steps:
Gas-liquid separator is arranged in indoor set, the outlet of the arrival end of the inlet pipe of this gas-liquid separator with the outdoor heat exchanger of off-premises station is connected, the port of export of pipe that goes out of gas-liquid separator is connected with the entrance of the throttling arrangement of indoor set, start refrigerating operaton, the gas-liquid two-phase refrigerant that heat exchanger is discharged outdoor flows through gas-liquid separator, and gaseous coolant is stored by gas-liquid separator and liquid refrigerants flows into the throttling arrangement throttling of indoor set.
Utilize gas-liquid separator to carry out the method for noise reduction compared with prior art to the indoor set of air-conditioning when the gas-liquid separator of air-conditioning of the present invention and refrigeration, have the following advantages.
First, gas-liquid two-phase refrigerant is discharged from the port of export of inlet pipe, and the port of export upwarps, and this strand of refrigerant also upwards sprays naturally, and liquid refrigerants just in time bumps against baffle plate, the whereabouts that is blocked deposits to tubular shell bottom, and gas is owing to gently swimming in tubular shell top, and liquid refrigerants constantly accumulates in bottom, liquid level rises, and then enter out tube inlet end, be finally all the refrigerant of pure liquid state from what go out that pipe discharges, namely this gas-liquid separator achieves and is stored by gaseous coolant and discharged by liquid refrigerants; And the method is due to by before the throttling arrangement of machine disposed in the interior for this gas-liquid separator, therefore ensure that what enter throttling arrangement is all pure liquid refrigerants, noise when avoiding problems gas-liquid two-phase coolant throttle and abnormal sound, eliminate noise, perfect Consumer's Experience.
