Abstract
The invention discloses a multifunctional gas-liquid separator used for a heat pump system. The multifunctional gas-liquid separator is a columnar cylinder, and is equipped with a middle clapboard with a ascending pipe for dividing the gas-liquid separator into an upper cylinder and a lower cylinder, a overheat pipe for overheating gaseous condensing agent at low pressure side is arranged in the upper cylinder, can effectively avoids liquid drop from directly entering into a compressor and liquid impact phenomenon, and improves life of the compressor; a supercooling pipe for supercooling liquid condensing agent at high pressure side and reboiling liquid drop at the low pressure side is arranged at the lower cylinder, improves heat transferring performance of a evaporator, working environment of a expansion valve, and low-temperature performance of a heat pump, and effectively increases heating capacity. The separator has multiple functions and simple structure, and can be used for heat pump circulation, especially heat pump heat supply circulation.
Description
Technical field
The present invention relates to field of air conditioning, particularly the heat pump heat supply cycle art.
Background technology
In order to prevent that drop from directly entering compressor, before the suction inlet of compressor, gas-liquid separator is installed usually, produce liquid hit phenomenon to avoid compressor.
But, even gas-liquid separator in fact has been installed, can not avoid drop to enter compressor, sometimes even also can be very serious, for example heat circulation time, because of environment temperature reduces at low temperature environment, the evaporimeter caloric receptivity is few, unevaporated liquid condensation agent is increased, thereby increased drop suction compressor, thereby the possibility that produces liquid hit phenomenon increases.
In order to reduce liquid condensation dosage in the separator, the certain external energy of input in separator that has is as solar energy, electric energy and heat energy etc., in the hope of evaporate a part of drop again in separator.Yet even so, it can't avoid drop to enter compressor fully, moreover extraneous input energy has increased energy consumption, influences the Energy Efficiency Ratio of heat pump.
Summary of the invention
At the deficiencies in the prior art, the invention provides and a kind ofly can effectively avoid drop to enter compressor, prevent liquid hit phenomenon, simultaneously, can make the high-pressure side condensate liquid cold excessively again, improve heat pump cold operation performance, increase the multifunctional gas-liquid separator of heat pump heating capacity.
Gas-liquid separator of the present invention is a pillar buoy, and high 2/3 place is provided with a central dividing plate at tube, and it is divided into upper and lower two, and described top cylinder is provided with the superheater tube that makes the low-pressure side condensed gas overheated in this; Described doffing is provided with in this tube the low-pressure side liquid refrigerant is seethed with excitement again, the supercooling tube that the high-pressure side condensed fluid is cold excessively, described central dividing plate which is provided with tedge, make after doffing separates the condensation of gas agent through it rise to top cylinder carry out overheated.
Described superheater tube is a kind of thermal source that provides, heating makes its overheated device from the condensation of gas agent of doffing, thereby effectively avoids drop to enter compressor, prevents liquid hit phenomenon, the import of this superheater tube links to each other with the condensator outlet arm, and its outlet links to each other with the outlet of doffing supercooling tube.
Described supercooling tube be a kind of provide liquid refrigerant in the vapour mixture that thermal source makes flash-pot seethe with excitement again and manage in the cold excessively device of high temperature condensed fluid, the import of this supercooling tube links to each other with the outlet of condenser, its outlet links to each other with expansion valve.Outside supercooling tube, because vapour mixture is heated a part of liquid condensation agent is seethed with excitement again, this has increased condensation of gas dosage on the one hand, thereby has improved heat pump cold operation performance, has improved heating capacity.On the other hand, can make vapourator full-liquid work, thereby improve the evaporimeter heat transfer property, meanwhile, supercooling tube inner high voltage side condensed fluid is cold excessively because of heat release, and this has improved the working environment of expansion valve on the one hand, has improved the heat pump heating capacity on the other hand again.
Also can establish some baffle plates before tedge, rising steam is through baffling, because inertia, in the liquid layer, gas then entered top cylinder through tedge, to improve gas-liquid separation effect at the bottom of drop fell after rise tin again.
Description of drawings
Fig. 1 is the heat pump heat distribution system flow chart of multifunctional gas-liquid separator of the present invention.
Fig. 2 is the structural representation of multifunctional gas-liquid separator of the present invention.
The specific embodiment
Among Fig. 1,1 is compressor, and 2 is condenser, and 3 are gas-liquid separator of the present invention, and 4 is throttling arrangement, and 5 is evaporimeter.
Among Fig. 2,4 is central dividing plate, and it is divided into upper and lower two with gas-liquid separator, and 1 is doffing, and 5 is top cylinder, and 6 is superheater tube, and 7 is supercooling tube, and 3 is vapor uptake, and 2 is hydraulic barrier.
When the heat pump heating operation, in top cylinder, enter superheater tube 6 top cylinder from being responsible for a1 through arm a11 from the high temperature condensing agent behind the condenser,, and carry out heat exchange here, make the gaseous state condensing agent that to a certain degree overheated be arranged from the cryogenic gaseous condensing agent in the doffing, then, enter compressor by the b2 adapter, the effective like this situation of having avoided drop directly to enter compressor has prevented liquid hit phenomenon.
In doffing, enter in the supercooling tube 7, here through taking over a1 from the high temperature condensing agent of condenser, carry out heat exchange with coming flash-pot through the vapour mixture that the b1 adapter enters, a part of liquid condensation agent is seethed with excitement again, like this, improved heating capacity on the one hand, on the other hand, can make vapourator full-liquid work, improve its heat transfer property, meanwhile, the high-temp liquid condensing agent is cold excessively in the pipe, has improved the expansion valve working environment and has improved the operation of heat pump performance.
For the compressor suction degree of superheat is controlled, on the a11 arm, be provided with the valve (not shown) that band control opens and closes, temperature can be used as a kind of control signal, when inlet temperature surpasses certain limit, makes valve close and open under the effect of control signal.
