Description
Technical field
The utility model relates to a kind of cold coal circulatory system.
Background technology
At present, general multi-joint machine coolant circulating system causes the refrigerant throughput of restricting element to reduce because the influence of factors such as drop, pipe range, elbow, reducing, shunting descends dynamic pressure decline, flow velocity, thereby the underfed that causes distance individual air-conditioner far away, refrigerating capacity descends.
As shown in Figure 1, traditional coolant circulating system comprises compressor A, condenser B, tube connector C, restricting element D, evaporimeter E.As shown in Figure 2, in this traditional coolant circulating system, after refrigerant flows through tube connector C (promptly, after point 3 point of arrivals 4 from figure), as can be seen, the pressure drop that is caused by drag losses is Δ P1 from p-h figure, that is to say, because refrigerant is because friction loss and pressure reduce (as shown in Figure 2, choke pressure drop is Δ P), thereby refrigerant flows through the also corresponding minimizing of flow of restricting element as can be known.
The utility model content
The utility model is devoted to overcome the above-mentioned defective of prior art just and is made.
The purpose of this utility model is to provide a kind of coolant circulating system, and it comprises: compressor, condenser, tube connector, restricting element, evaporimeter and be arranged at condenser and tube connector between supercharging device.
Preferably, supercharging device is a booster pump.
Booster pump comprises impeller, pump case, pump shaft, fluid intake, liquid outlet, and preferably, pump case is the volute pump case.
Preferably, impeller has the blade of 4 to 12 palintropes.
Preferably, supercharging device is suitable along the pressure loss in the described tube connector flow process to the supercharging amount and the refrigerant of refrigerant.
Can be used for according to coolant circulating system of the present utility model in the air-conditioning system of remote feed flow of needs or high-rise feed flow, the supercharging device of this system carries out supercharging to the liquid refrigerants in the pipeline, in order to overcome owing to flow resistances such as pipe range, elbow, reducing, shuntings, improve the dynamic pressure of liquid refrigerants, the flow velocity of raising refrigerant, eliminate the adverse effect that the refrigerant pressure loss is brought, thereby improve the flow that refrigerant flows through restricting element, improved refrigerating capacity.
Other features and advantages of the utility model provide in explanation subsequently, partly can be apparent from the description, and maybe can find out from enforcement of the present utility model.The purpose of this utility model and other advantage can be understood, obtain from the structure that following written explanation, claim and accompanying drawing provide especially.
Should be appreciated that above generality is described and the following detailed description is all enumerated and illustrative, purpose is in order to provide further instruction to claimed the utility model.

Fig. 6 illustrates difference according to coolant circulating system and the traditional coolant circulating system of the utility model embodiment with p-h.
The specific embodiment
Below the detailed description of some embodiment has been provided various explanations to the utility model specific embodiment.This description taken in conjunction accompanying drawing carries out, and identical in the accompanying drawings parts are represented with identical label.
With reference to Fig. 3, comprise according to coolant circulating system of the present utility model: compressor A, condenser B, tube connector C, restricting element D, evaporimeter E and supercharging device F, wherein supercharging device F is arranged between described condenser B and the described tube connector C.
Supercharging device F can be booster pump, as shown in Figure 4.Booster pump F comprises: impeller 11, pump case 12, pump shaft 13, fluid intake 14, liquid outlet 15.Wherein, impeller 11 constitutes the high speed rotating part of booster pump F, and pump case 12 constitutes the stationary part of booster pump F.
Before the booster pump F work, earlier with the full liquid of stream in the pump, start booster pump then, impeller 11 quick rotation, the blade of impeller 11 orders about liquid and rotates, when rotating, liquid rely on inertia to impeller 11 outer rim diffluences, impeller 11 is from suction line inspiration liquid simultaneously, in this course, the liquid in the impeller streams blade, and liquid is to blade effect one lift in streaming motion, blade is to liquid effects lift equal and opposite in direction, power that direction is opposite therewith conversely, this power is done work to liquid, makes liquid obtain energy and flows out impeller, and the dynamic pressure of liquid at this moment increases.
Below, in conjunction with p-h map analysis shown in Figure 5 according to the pressurization with coolant circulating system of supercharging device of the present utility model.After refrigerant is flowed out by compressor A, pressure increases to p ' (1-2 Fig. 3) from p, after this in condenser B, arrive supercharging device F through isobaric change procedure (2-3 among Fig. 3), the pressure of refrigerant via supercharging device F supercharging after, pressure increases to p from p " (3-3 ' Fig. 3).
Preferably, supercharging device F is chosen to and the pressure of refrigerant can be increased to p from p ' ", wherein; wherein " and the difference of p ' is the drag losses of restricting element to p, be Δ P1, that is supercharging device F is suitable along the friction loss in the tube connector flow process to the supercharging amount and the refrigerant of refrigerant.
With reference to Fig. 6, the figure shows difference according to coolant circulating system and the traditional coolant circulating system of the utility model embodiment.As can be seen from Figure 6, in traditional coolant circulating system, when refrigerant arrives tube connector C (when arriving 3 among Fig. 1), the pressure of refrigerant is p ', so (when promptly arriving 4 among Fig. 1) pressure becomes (p '-Δ P1) after refrigerant flows through tube connector C.And in the coolant circulating system according to the utility model embodiment, because the existence of supercharging device F, make when refrigerant arrives tube connector C (arriving 3 ' time among Fig. 3), the pressure of refrigerant is p "; so, after refrigerant flows through tube connector C, (promptly arrive 4 ' time among Fig. 3) pressure becomes (p " Δ P1).From the above, p "＞p '; so (p " Δ P1)＞(p '-Δ P1), that is to say, compare with traditional coolant circulating system that does not have supercharging device, according to the pressure when arriving restricting element D of the refrigerant in the coolant circulating system of the utility model embodiment bigger, therefore correspondingly improved the flow that refrigerant flows through restricting element D, improved refrigerating capacity.
Although the utility model is illustrated with reference to accompanying drawing and preferred embodiment, obviously, for a person skilled in the art, under the prerequisite that does not deviate from spirit and scope of the present utility model, can make various changes and variation to the utility model.Various change of the present utility model, the content that changes by appending claims and equivalent thereof contain.
