Background technology:
In existing heat pump circulating system, after refrigerant is compressed by compressor, be discharged in the radiator by compressor, to high temperature heat source release heat and condensation, by throttling, the refrigerant pressure and temperature all reduces when passing through throttling arrangement again, enter evaporimeter then, absorb heat and evaporation from low-temperature heat source, reenter compressor at last and be compressed, finish a complete cycle.But the liquid refrigerants in this heat pump circulating system after the cooling becomes the vapour-liquid of low pressure lower temperature after throttling arrangement throttling step-down mixes refrigerant (about 90% liquid state, 10% gaseous state), owing to be mixed with gaseous coolant in the liquid refrigerants, refrigerant skewness after entering evaporimeter has influenced the refrigeration of evaporimeter.
The utility model content:
The purpose of this utility model be exactly the deficiency that exists at prior art and provide a kind of and can export pure liquid refrigerants, guarantee that refrigerant is evenly distributed on the evaporimeter, the heat pump of good refrigeration effect is with binodal stream imbibition type liquid distributing device.
To achieve these goals, the technical solution adopted in the utility model is:
Heat pump flows the imbibition type liquid distributing device with binodal, it includes a nuclear one-stage throttling device, the outlet of one nuclear one-stage throttling device is connected with the two-step throttle liquid distributing device, the two-step throttle liquid distributing device comprises liquid storage cylinder, feed tube and Duo Gen separatory capillary, the inlet of feed tube is connected with the outlet of a nuclear one-stage throttling device, the outlet of feed tube is passed and is stretched in the inner chamber of liquid storage cylinder by the bottom of liquid storage cylinder, many separatory are capillaceous goes into mouth down and stretches in the inner chamber of liquid storage cylinder, and the outlet of feed tube is higher than separatory inlet capillaceous.
The outlet of described feed tube is higher than separatory inlet capillaceous 10mm at least.
Described feed tube adopts brazing mode to fixedly connected with the junction of liquid storage cylinder.
A described nuclear one-stage throttling device is heating power expansion valve, electric expansion valve or capillary-compensated device.
The utility model beneficial effect is: the utility model includes a nuclear one-stage throttling device, the two-step throttle liquid distributing device, the two-step throttle liquid distributing device comprises liquid storage cylinder, feed tube and Duo Gen separatory capillary, the outlet of feed tube is passed and is stretched in the inner chamber of liquid storage cylinder by the bottom of liquid storage cylinder, many separatory are capillaceous goes into mouth down and stretches in the inner chamber of liquid storage cylinder, liquid refrigerants after the cooling becomes the liquid refrigerants of low pressure lower temperature after a nuclear one-stage throttling device throttling step-down, enter in the liquid storage cylinder by feed tube, utilize the liquid storage function of liquid storage cylinder, make gaseous state and liquid refrigerants layering after a nuclear one-stage throttling device throttling step-down, because of the feed tube outlet is higher than the separatory capillary inlet, the feasible pure liquid refrigerants that is the low pressure lower temperature that enters in the separatory capillary; And utilize separatory siphon capillaceous, Throttle Principle, make that refrigerant is evenly distributed good refrigeration effect on the evaporimeter.
Description of drawings:
