Of the present utility model operation principle and preferred embodiment are described below
A kind of this utility model novel gas-liquid separator device, this device be used for steam compression system in, throttle mechanism with Between vaporizer, the automatical and efficient separation of refrigerant gas after this device can be realized throttling, and isolate gas Loop, gas can be led back the branch of compressor air suction mouth or vaporizer by this loop.Another road fluid path can directly be entered Enter in evaporator pipeline, realize efficient heat exchange.
The technical problem solving:
1st, the vaporizer pressure drop that gaseous refrigerant causes in the flowing of dry evaporator pipeline high speed is bigger than normal.
2. gaseous refrigerant prevents the contact of liquid refrigerant and heat exchange tube wall in dry evaporator pipeline, increases Thermal resistance, reduces the heat exchange efficiency of vaporizer.
Beneficial effect:
Reduce the flow velocity of cold-producing medium in dry evaporator, reduce pressure drop, indirectly reduce the power of compressor, from And lift the performance of unit.
By reducing the thermal resistance of vaporizer, improve the heat exchange efficiency of vaporizer, the area of vaporizer can be reduced, save material Material.
The structure of special gas block panel and leakage plate realizes the high efficiency separation of liquid refrigerant and gaseous refrigerant.
As Figure 2-3:Cold-producing medium after throttling enters cylinder 1 by two phase refrigerant import, diffusion fall in cylinder 1 Speed, in the presence of gas block panel 6 and leakage plate 5, liquid refrigerant is deposited on the least significant end of cylinder 1, gas by the hole of leakage plate 5 Body filters after gas block panel with leakage plate in defecator 7, filters down liquid refrigerant further, and gaseous refrigerant leads to Cross upper gas outlet 3 discharge of cylinder.
This device is used in steam compression system, between throttle mechanism and vaporizer, can realize throttling by this device The automatical and efficient separation of refrigerant gas afterwards, and have the loop isolating gas, gas can be led back by compression by this loop Machine air entry or the branch of vaporizer.Another road fluid path can be directly entered in evaporator pipeline, realizes efficient heat exchange.
This novel gas-liquid separator device is used in steam compression circulating system, and cold-producing medium is within the condenser after condensation Become the liquid of high pressure, become gas-liquid two-phase state through the throttling action of choke valve.Gaseous refrigerant can weaken liquid refrigerant Evaporation in vaporizer.Thus affecting the high-efficiency operation of whole refrigeration system, by this device, can be by after throttling Two phase refrigerant in gaseous refrigerant separate from system, thus avoid gaseous refrigerant to liquid refrigerant steam The evaporation sent out in device produces impact.Realize the separation of the two-phase fluid after throttling, ensure that entrance evaporation pipeline is all liquid Cold-producing medium, is capable of more efficient heat exchange, meanwhile can return to the gaseous refrigerant separated by other pipelines Compressor machine air entry, or by single evaporator circuit carry out overheated after return compressor inlet.
The shape of cylinder arbitrarily can be changed according to practical situation and needs, adapter position also dependent on practical situation and Needs are arbitrarily changed.
Those skilled in the art is it is easily understood that on the premise of not conflicting, above-mentioned each advantageous manner can be free Ground combination, superposition.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all this Any modification, equivalent and improvement made within the spirit of utility model and principle etc., should be included in this utility model Protection domain within.The above is only preferred implementation of the present utility model it is noted that for the art For those of ordinary skill, on the premise of without departing from this utility model know-why, some improvement and change can also be made Type, these improve and modification also should be regarded as protection domain of the present utility model.
