Description
Technical field
The utility model relates to the air-cooled evaporimeter of a kind of air source heat pump and divides liquid systems.
Background technology
Air source heat pump is a kind of efficient energy conversion device, and it absorbs heat from air in the winter time, and by compressor work, it is heat of high temperature that the low-temperature heat quantity of air is promoted, and this heat is used for building winter heating and health hot water.Energy-conservation along with country, as to reduce discharging situation development, this efficient heat energy conversion equipment more and more obtain paying attention to and using.But because air source heat pump efficient decay under the low temperature condition in the winter time, wherein one of greatest factor is air-cooled evaporimeter because the separatory inequality time, it is inhomogeneous that the wind speed of air-cooled evaporimeter is crossed in circulation of air, causes air-cooled evaporator effectiveness low, and the heating effect of heat pump descends.The air-cooled evaporimeter of present air source heat pump normally " V " font arranges that top is provided with axial flow blower 4 (as shown in Figure 1), is characterized in this air-cooled evaporation structure compactness, and the refrigerating system coolant line arrangement is simple.But because this air-cooled evaporimeter " V " font arranges, the air stream of the top and the bottom by this evaporimeter is inhomogeneous.The heat transfer intensity of refrigerant and air is big in the air velocity height on the air-cooled evaporimeter of " V " type 1 top wherein, evaporimeter, and refrigerant fully evaporates, and is not with liquid.And form one " V air-flow dead band " in the lower part of air-cooled evaporimeter 1, and as a-quadrant among the figure, air velocity is low, and refrigerant and air heat transfer intensity are little in the heat exchanger, and refrigerant can not fully evaporate, and band liquid phenomenon is arranged.In addition, the length of each road capillary separating tube 2 of air-cooled evaporimeter 1 is equally long, vapour, the flow resistance of liquid two-phase refrigerant in capillary separating tube 2 after knockout 3 mixes and distributes are identical, its flow is also identical, cause the air-cooled evaporimeter of this " V " type lower part because air-flow is little, inadequate another key factor of refrigerant evaporation.Because the refrigerant evaporation in the air-cooled evaporimeter is insufficient, the heating effect of unit is poor, simultaneously, owing to there is not the liquid refrigerants of evaporation to suck compressor, cause the compressor liquid hammer, influenced the security and the reliability of compressor, compressor is with the liquid operation for a long time, its short in service life, and this is the difficult problem that the air source heat pump of the air-cooled evaporimeter of " V " type at present faces.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provides a kind of and evaporates the air-cooled evaporimeter abundant, that heat exchange efficiency is high and divide liquid systems.
The technical scheme that the utility model adopted is: the branch liquid systems of some the capillary separating tubes that the utility model comprises vaporizer body, is positioned at the axial flow blower on described vaporizer body top and comprises knockout and draws from knockout, the other end of described some capillary separating tubes is connected to each the road evaporimeter in the vaporizer body respectively, be provided with a segment distance between the evaporimeter of both sides, described vaporizer body bottom, the described vaporizer body longitudinally cross sectional shape of axis is down trapezoidal shape.
The branch liquid systems that comprises the knockout and some the capillary separating tubes of drawing is distributed to the capillary separating tube with the refrigerant in the pipeline and is entered each road evaporimeter on the vaporizer body, the length that is connected in some capillary separating tubes on the described vaporizer body is elongated gradually along with reducing of air velocity from top to bottom, and its separately length and the linear distribution of air velocity be complementary.Be that the separatory capillary is the shortest, branch liquid measure maximum is the air-cooled evaporimeter top first via, and the separatory capillary is the longest, the branch liquid measure is minimum to be a road of air-cooled base of evaporator, and middle separatory capillary pipe length is linear distribution.
The caliber of described some capillary separating tubes is identical.
The beneficial effects of the utility model are: owing to be provided with a segment distance between the evaporimeter of both sides, described vaporizer body bottom, the described vaporizer body longitudinally cross sectional shape of axis is down trapezoidal shape, so the air-cooled evaporimeter face velocity of this structure is linear distribution along air-cooled evaporimeter height, bottom air stream face velocity at air-cooled evaporimeter still satisfies the heat exchange requirement simultaneously, and comparing existing air-cooled evaporimeter does not have " V air-flow dead band ".Because the fluid on-way resistance is directly proportional with length under identical caliber condition, the separatory capillary pipe length is short, and the resistance that vapour, liquid two-phase refrigerant pass through is little, and its flow is big, and what be complementary with it is the cold evaporimeter of a transportation work style big by air velocity, that heat transfer intensity is big; Separating tube length is long, and the resistance that vapour, liquid two-phase refrigerant pass through is big, and its flow is little, and what be complementary with it is the road evaporimeter little by air velocity, that heat transfer intensity is little.According to the above-mentioned air-flow linear distribution that is down the air-cooled evaporimeter of trapezoidal shape, corresponding separatory capillary pipe length with tool also is linear distribution, the refrigerant that makes each road knockout of air-cooled evaporimeter distribute like this can both evaporate fully, realizes that whole air-cooled evaporimeter efficiently moves.
