Description

[0001] The present invention relates to an agitation apparatus for refrigerant having impeller,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a refrigerant agitating apparatus having an impeller, and more particularly, to a refrigerant agitating apparatus having an impeller which stirs refrigerant circulated in a cooling / heating system for a heat pump with fine particles, .

Generally, a heat pump is used to transfer heat from a low temperature to a high temperature by applying a work to a refrigerant circulating along a pipeline. When heat is discharged from a refrigerant, it can be used as a heater or a water heater. The process of absorbing heat can be used as a cooler or a freezer.

The system of such a heat pump is composed of an evaporator, a compressor, a condenser and an inflator as shown in Fig. 1, and the refrigerant can be repeatedly circulated via the components.

Specifically, the system of the heat pump absorbs the heat source as the refrigerant travels to the evaporator and becomes a gas when it meets various heat sources such as the waste heat. The vaporized low temperature and low pressure refrigerant is delivered to the condenser at high temperature and high pressure in the compressor. The heat exchanger exchanges heat with the cold water in the condenser to absorb the heat of the refrigerant, liquefies the refrigerant into a high-temperature and high-pressure liquid, expands the refrigerant in the expander, reduces the pressure and temperature, Lt; / RTI >

Here, the evaporator is a heat exchanger, which recovers the discarded heat source. When the sludge is introduced and accumulated, the efficiency is lowered and the system of the heat pump can be damaged. Compressor is used as a compressor to compress low temperature and low pressure refrigerant vaporized in an evaporator to high temperature and high pressure. The condenser is a condenser, which cools the refrigerant compressed at a high temperature and a high pressure in a compressor to cool the refrigerant to a high-temperature, high-pressure liquid. The inflator can expand the refrigerant, which is a liquid at high temperature and high pressure, to reduce the pressure and the temperature, and then maintain the liquid at a low temperature and a low pressure.

However, Korean Patent Registration No. 10-1128389, which is a system of a conventional heat pump, has a problem in that the refrigerant, which is a fluid repeatedly circulated through the constituent elements, performs repetitive circulation so that the refrigerating oil partially contained in the refrigerant is not finely distributed, And the viscosity of the entire refrigerant increases. In addition, since the frictional resistance and the flow resistance in the conduit are increased by increasing the viscosity of the refrigerant, it is pointed out that it is a factor that greatly increases the power consumption during operation of the heat pump system.

Refrigerant Stirring  process

8 is a block diagram showing a refrigerant agitation procedure of a refrigerant agitation apparatus equipped with an impeller of the present invention.

 Hereinafter, with reference to FIG. 8, a description will be made of a process in which the refrigerant agitator 10 of the cooling system for the heat pump and the refrigerant agitator 20 of the heating / cooling system for the heat pump agitate the refrigerant.

First, the refrigerant agitators 10 and 20 cause the refrigerant circulating through the evaporator 1, the compressor 2, the condenser 3 and the inflator 4 to flow into the interior of the stirring tank 100 (S100 ). At this time, in the refrigerant agitator 10 and the refrigerant agitator 20 in the cooling mode, the refrigerant flows along the inflow pipe 120 and flows into the inside of the fluid tank 110. On the other hand, in the case of heating, the coolant agitator 20 flows the coolant along the outflow pipe 130 and into the inside of the fluid tank 110.

When the refrigerant flows into the flow tank 110, the refrigerant agitators 10 and 20 firstly stir the refrigerant (S200). At this time, in the refrigerant agitator 10 and the refrigerant agitator 20 in the cooling mode, the first impeller 210 first stirs the refrigerant. On the other hand, in the case of heating, the refrigerant agitating device 20 causes the second impeller 310 to firstly stir the refrigerant. On the other hand, the first impeller 210 and the second impeller 310 induce atomization of the refrigerant through the primary agitation, thereby lowering the overall viscosity of the refrigerant.

When the refrigerant is firstly stirred, the refrigerant agitators 10 and 20 agitate the refrigerant, which is firstly stirred and stirred, in the second stage (S300). At this time, in the refrigerant agitating device 10 and the refrigerant agitating device 20 in the cooling mode, the second impeller 310 secondarily stirs the refrigerant. On the other hand, in the case of heating, the refrigerant agitator 20 causes the first impeller 210 to secondarily stir the refrigerant. On the other hand, the first impeller 210 and the second impeller 310 further induce atomization of the refrigerant through the secondary agitation and lower the overall viscosity of the refrigerant.

At this time, if the ultrasonic vibrator 400 is provided in the refrigerant agitators 10 and 20 and the ultrasonic wave inducing the evaporation phenomenon occurs in the refrigerant in the ultrasonic vibrator 400, the secondary agitation process of the refrigerant is performed by the ultrasonic vibrator 400) by ultrasonic waves. As a result, the two refrigerants are more atomized than the stirring process through the first impeller 210 and the second impeller 310, and the overall viscosity of the refrigerant can be further lowered. Meanwhile, if the second stirring process of the refrigerant is a stirring process of the ultrasonic vibrator 400 through ultrasonic waves, the process of second stirring the refrigerant by the first impeller 210 or the second impeller 310 may include It would be desirable to look at the tea stirring process. However, when the ultrasonic vibrator 400 does not generate ultrasonic waves, the process of stirring the refrigerant through the first impeller 210 or the second impeller 310 may be a second stirring process of the refrigerant.

When the refrigerant is secondarily stirred, the refrigerant agitators 10 and 20 discharge the refrigerant to the outside of the flow tank 110 (S400). At this time, the refrigerant agitator 10 and the refrigerant agitator 20 in the cooling mode flow out the refrigerant to the outside of the flow tank 110 through the outlet pipe 130. On the other hand, when the refrigerant is heated, the refrigerant agitator 20 discharges the refrigerant to the outside of the flow tank 110 through the inflow pipe 120.

If the second stirring process of the refrigerant agitators 10 and 20 is a stirring process of the ultrasonic vibrator 400 through ultrasonic waves, the refrigerant flows through the first impeller 210 or the second impeller 310, And may be discharged to the outside of the fluid bath 110 after the stirring process.
