Alternate path and second heat exchanger 1-2 the first access sequential flowing.Although the attachment device 2 of second embodiment
Width go out to be equivalent to greatly than the width of the attachment device 2 of first embodiment a fluid inflow and outflow opening it is wide
Degree, but can have the effect of dual refrigeration cycle, and the installation space of refrigeration machine can be reduced.
Next, referring to Fig.1 1 to Figure 14 in order to form three in the inside of substantially cylindric attachment device main body 21
The structure of the attachment device 2 of a room R1, R2, R3 illustrates.In order to the inside of attachment device main body 21 formed three room R1,
R2, R3 and be provided with 2 pieces of demarcation strips 22, in the following description, in order to distinguish 2 pieces of demarcation strips 22 and after reference numeral 22 it is attached
A, B is added to illustrate.
Figure 11 and Figure 12 is the stereogram from first heat exchanger 1-1 unilateral observations attachment device 2.Such as Figure 11 and figure
Shown in 12, attachment device 2 has the first Room R1 and second Room R2 in first heat exchanger side.First Room R1 is by substantially semi-circular plate
The space that the inner peripheral surface of the demarcation strip 22A of shape, the demarcation strip 22B of substantially rectangular plate and attachment device main body 21 surround.The
Two Room R2 are the spaces surrounded with the inner peripheral surface of attachment device main body 21 by the demarcation strip 22B of above-mentioned rectangular plate-like.First opening
A1 is connected to the first Room R1.
Figure 13 and Figure 14 is the stereogram from second heat exchanger 1-2 unilateral observations attachment device 2.Such as Figure 13 and figure
Shown in 14, attachment device 2 has second Room R2 and third room R3 in second heat exchanger side.Second Room R2 is and Figure 11 and figure
The identical rooms second Room R2 shown in 12.Third room R3 is by point of the demarcation strip 22A of substantially semicircle plate, substantially rectangular plate
The space that partition board 22B and the inner peripheral surface of attachment device main body 21 surround.Second opening A2 is connected to third room R3.
As shown in Figure 11 to 14, in the attachment device of the utility model 2, by the inside of attachment device main body 21
2 pieces of demarcation strips 22A, 22B are set, to form two rooms R1, R2 in first heat exchanger side, are formed in second heat exchanger side
Two rooms R2, R3.Thereby, it is possible to make the first Room R1 and the access of a side of first heat exchanger 1-1 be connected to, make second Room R2 with
The access of another party of first heat exchanger 1-1 is connected to, and is connected to the access of a side of second heat exchanger 1-2, makes the
Three Room R3 are connected to the access of another party of second heat exchanger 1-2.
Next, to single in the refrigerator system for connecting the shell-and-tube exchanger of two paths of two refrigeration machines
The difference that refrigeration cycle is circulated in dual refrigeration in efficiency illustrates.In the following description, illustrate the first evaporation
The case where device is first heat exchanger, the second evaporator is second heat exchanger.
Figure 15 (a) is denoted as the connection method of the first evaporator and the second evaporator of single refrigeration cycle, Figure 15 (b)
It is denoted as the connection method of the first evaporator and the second evaporator of dual refrigeration cycle.Connection method shown in Figure 15 (b)
It can implement in the first embodiment of the utility model.
(1) in the connection method shown in Figure 15 (a), cold water is according to access, the second evaporator on the upside of the first evaporator
The sequential flowing of the access on the downside of access and the first evaporator on the downside of the access of upside, the second evaporator.
(2) in the connection method shown in Figure 15 (b), cold water is according to the first access on the downside of the first evaporator, the first steaming
Send out the sequence of the alternate path on the upside of device, the alternate path on the upside of the first access and the second evaporator on the downside of the second evaporator
Flowing.
Generally, in the case where connecting two heat exchangers, there are the companies as single refrigeration cycle shown in Figure 15 (a)
The connection method 2 recycled as dual refrigeration shown in method 1 and Figure 15 (b) is connect, and connection method 1 and connection method 2 divide
Do not consider not as described below.
In the current method of connection method 1, if so that cold water is flowed in the first evaporator and the second evaporator, and with evaporation
Device is same, makes cooling water in the flowing (not shown) of the first condenser and the second condenser, then the first evaporator and the second evaporator
Inside temperature and pressure it is roughly the same, equally, the temperature and pressure of the inside of the first condenser and the second condenser
Also roughly the same therefore identical as the case where there are two simple subprograms.
In the current method of connection method 2, if so that cold water is flowed in the first evaporator and the second evaporator, and with evaporation
Device is same, makes cooling water in the flowing (not shown) of the first condenser and the second condenser, then the first evaporator and the second evaporator
Inside temperature and pressure it is different, equally, the temperature and pressure of the inside of the first condenser and the second condenser are not yet
Together, therefore it is identical as there is the case where 1 dual refrigeration recycles.
Next, illustrating the difference of the work done during compression of above-mentioned single refrigeration cycle and dual refrigeration cycle.
Figure 16 is the relationship of the cold water or cooling water temperature and specific entropy that indicate single refrigeration cycle and dual refrigeration cycle
Curve graph (indicates the work done during compression in Ideal Cycle).Dotted line indicates that simple subprogram, solid line indicate dual refrigeration cycle.Dual refrigeration
Cycle is made of two cycles of high pressure and low pressure, and upside indicates that the cycle of high pressure, downside indicate the cycle of low pressure.
The cartographic represenation of area work done during compression of Figure 16.Although compressor makes the temperature fall from evaporating temperature to condensation temperature rise,
But there is in dual refrigeration cycle in refrigeration machine the cycle of two systems, therefore average temperature fall (drop can be reduced
The differential pressure of the sucking and discharge of low each compressor) improve efficiency.The area of the oblique line of Figure 16 become single refrigeration cycle with
The difference of the work done during compression of dual refrigeration cycle.
In this way, in the case where connecting two heat exchangers, compared with single refrigeration recycles, it is connected as dual refrigeration cycle
Connection work done during compression smaller, as a result can reduce the electric power of main motor.
Figure 17 (a), Figure 17 (b) are to indicate to utilize attachment device by the evaporator of the first refrigeration machine and condenser and second
The figure of the surface structure for the compression refrigerating machine system that the evaporator and condenser of refrigeration machine are connected with each other, Figure 17 (a) is main
View, Figure 17 (b) are rearviews.
As shown in Figure 17 (a), Figure 17 (b), the first refrigeration machine REF1 has the first evaporator E1, the first compressor Comp1
And the first condenser C1.Second refrigeration machine REF2 has the second evaporator E2, the second compressor Comp2 and the second condenser
C2。
The second evaporator E2 of the first evaporator E1 and the second refrigeration machine REF2 of first refrigeration machine REF1 are new by this practicality
The attachment device 2 of type connects.The second condenser C2 of the first condenser C1 and the second refrigeration machine REF2 of first refrigeration machine REF1
It is connected by the attachment device 2 of the utility model.
So far, the embodiment of the utility model is illustrated, but the utility model is not limited to above-mentioned implementation
Mode can be implemented in a variety of ways certainly within the scope of its technical ideas.
