Brief description of the drawings
Fig. 1 is the cooling device of a kind of adjustable refrigerant effective dose under the utility model one embodiment.
Detailed description of the invention
The utility model provides a kind of cooling device of adjustable refrigerant effective dose, comprise return line, heat pump 1, condenser 3, throttling arrangement 4, evaporimeter 5 and refrigerant, heat pump 1 outlet connects condenser 3 imports, condenser 3 outlets connect the import of throttling arrangement 4, the outlet of throttling arrangement 4 connects the import of evaporimeter 5, the outlet of evaporimeter 5 connects the import of heat pump 1, and return line is provided with flow control valve 6, between throttling arrangement 4 and condenser 3, is provided with filter 2.The import of return line is connected in the pipeline between heat pump 1 and condenser 3 by three-way pipe, and the outlet of return line is connected in the pipeline between evaporimeter 5 and heat pump 1 by three-way pipe.
The utility model is by arranging return line at heat pump 1 both ends, when after heat pump 1 entry into service, refrigerant in evaporimeter 5 is inhaled into heat pump 1 from heat pump 1 suction inlet and compresses, pressure in evaporimeter 5 reduces gradually, low-pressure low-temperature refrigerant becomes high pressure-temperature refrigerant after heat pump 1 compression, again through condenser 3 to the processing of lowering the temperature of the refrigerant of HTHP, become the liquid refrigerants of high pressure low temperature, after filter 2 impurity screenings, again by the throttling processing of throttling arrangement 4, the refrigerant that the liquid refrigerants of high pressure low temperature becomes low-pressure low-temperature is in the interior vaporization of evaporimeter 5 and absorb heat, complete the air entry that refrigerant after heat exchange returns heat pump 1 and complete next circulation.After load lightens, when the interior heat exchange amount minimizing that needs heat exchange of evaporimeter 5, the refrigerant total amount that heat pump 1 compresses is out constant, load pressure when heat pump 1 moves is constant, the refrigerant total amount entering in evaporimeter 5 from throttling arrangement 4 still remains unchanged, refrigerant does not have enough heats can carry out heat exchange in evaporimeter 5, pressure and temperature in evaporimeter 5 can decline gradually, in the time setting value lower than flow control valve 6, flow control valve 6 is opened gradually, and a part of gases at high pressure come back to the suction inlet of heat pump 1 by flow control valve 6.Pressure and temperature in evaporimeter 5 is lower, the aperture that flow control valve 6 is opened is larger, by the capacity regulating of flow control valve 6, can reduce the running load pressure of heat pump 1 outlet side, the reduction that heat pump 1 exports refrigerant pressure can effectively reduce the refrigerant total amount that enters evaporimeter 5 heat exchange, realizes the constant control to relevant parameter with this.Avoided cold or overheated phenomenon to occur, when heat pump 1 moves under low load pressure state, the power consumption can effectively reduce operation time, realizes economize on electricity object.In the service life that has simultaneously extended device, make the utility model be suitable for various operating modes.
Such scheme, has effectively regulated the refrigerant effective dose that enters evaporimeter 5, has reduced load pressure when heat pump 1 moves, and effectively reduces the power consumption of heat pump, realizes the target of constant cryogenic temperature, reaches the object of saving the energy.
Above-mentioned refrigerant effective dose refers to that refrigerant enters the amount that is transferred to gas phase after evaporimeter 5 by liquid phase, because refrigerant effective dose is characterizing the size of heat exchange amount, therefore controls refrigerant effective dose and can effectively regulate heat exchange amount.The loop that generally, heat pump 1, condenser 3, throttling arrangement 4, evaporimeter 5 can be formed becomes refrigeration pipe.
The filter 2 arranging between throttling arrangement 4 and condenser 3 can filter the impurity in refrigerant, prevents that the impurity in lubricating grease and the pipeline in heat pump 1 from sneaking into the work generation harmful effect to refrigerant and throttling arrangement 4.
It should be pointed out that return line of the present utility model is connected in the pipeline between heat pump 1 and condenser 3 with its import, outlet is connected in the pipeline between evaporimeter 5 and heat pump 1.Can connect by three-way pipe, also can be two-tube by the import and export of heat pump are all set to, connect respectively refrigeration pipe and return line.The present embodiment is in the mode of three-way pipe as example, and it has the feature of easy enforcement simple in structure.
Further, in the time that the utility model is applied to air conditioner, can be by indoor dress temperature sensor, when temperature sensor is surveyed lower compared with the temperature of the temperature that obtains and setting time, aperture that can augmented flow control valve 6, can effectively reduce the load of heat pump 1.Aforesaid operations can also further arrange by the introducing automation of single-chip microcomputer.
Should also be noted that the pipeline that the import of above-mentioned return line can also be connected between condenser 3 and throttling arrangement 4 also can realize the utility model, other technologies feature is described above, repeats no more.
The above is only optimal way of the present utility model; it should be pointed out that to those skilled in the art, do not departing under the prerequisite of the utility model creation design; can also make some similar distortion and improvement, within these also should be considered as protection scope of the present invention.
