Time, improve production efficiency.
Further, the outdoor unit also includes throttle part 5, and throttle part 5 was arranged on communicating pipe 2.It can so lead to
Throttle part 5 is crossed to throttle to the refrigerant to circulate between outdoor heat exchanger 1 and indoor heat exchanger 4, to reduce the temperature of refrigerant,
Improve heat transfer effect.
Specifically, throttle part 5 includes the first capillary 51, and the both ends of the first capillary 51 are respectively with communicating pipe 2 and cutting
Only valve 3 connects.It is a kind of coolant throttle mode commonly used at present to coolant throttle using the first capillary 51, its work is former
Reason is no longer described in detail herein.In actual use, communicating pipe 2 can be shortened, replace being shortened communicating pipe 2 by the first capillary 51
Part, such as from the communicating pipe 2 for needing 3 meters between the refrigerant of stop valve 3 to the second interface 41 originally, it now is possible to by communicating pipe
2 become 2.1 meters, are supplemented additionally by 0.9 meter of the first capillary 51, to meet to connect the requirement of distance, due to capillary
Diameter (being usually 1.5 millimeters) is more much smaller than the diameter (being usually 6 millimeters) of communicating pipe 2, therefore can reduce material cost.Its
In the first capillary 51 and can continuously be welded together by reducer union between communicating pipe 2.
It should be noted that throttle part 5, which can also be heating power expansion valve or electric expansion valve etc., can realize throttling action
Part.
More preferably, in addition to connecting tube 6, the first capillary 51 are connected on stop valve 3 by connecting tube 6.Wherein, connect
Pipe 6 can use diameter to make more than the ordinary copper civil service system of the diameter of the first capillary 51, and length can depend on the circumstances, such as 20 lis
Rice, can continuously be welded together between the first capillary 51 and connecting tube 6 by reducer union.More preferably, connecting tube 6 has
First attaching nut 61；The first connection screw thread to match with the first attaching nut 61, the first connection spiral shell are provided with stop valve 3
Mother 61 is connected in the first connection screw thread, and connecting tube 6 is connected on stop valve 3.Can so make the first capillary 51 with
Disassembly and installation work between stop valve 3 becomes simpler, conveniently.
It should be noted that the mode that the second end of communicating pipe 2 can also be connected through a screw thread is connected to indoor heat exchanger 4
The second refrigerant interface 41 on, as shown in Figure 2, the second end of communicating pipe 2 can have the second attaching nut 21, indoor heat exchange
Second refrigerant interface 41 of device 4 is provided with connection member 42, has what is matched with the second attaching nut 21 in connection member 42
Second connection screw thread；Second attaching nut 21 is connected in the second connection screw thread, communicating pipe 2 to be connected by connection member 42
It is connected on the second refrigerant interface 41, the installation and removal to communicating pipe 2 provide conveniently.
As a kind of embodiment, as depicted in figs. 1 and 2, throttle part 5 is also more than the first capillary 51 including length
The second capillary 52.The both ends of second capillary 52 are connected with communicating pipe 2 and stop valve 3 respectively, and refrigerant can pass through second
Capillary 52 flows to outdoor heat exchanger 1.The first check valve 511 is provided with the first capillary 51, to prevent refrigerant through
One capillary 51 flows to outdoor heat exchanger 1.
The operation principle of the first capillary 51 and the second capillary 52 is illustrated by taking air conditioner as an example below：
In actual use, outdoor heat exchanger 1 is the condenser in air conditioner, and indoor heat exchanger 4 is the steaming in air conditioner
Send out device.When carrying out refrigeration work, refrigerant is exited into after the first capillary 51 is throttled from outdoor heat exchanger 1 makes refrigerant
Temperature reduces, and the refrigerant after cooling gets in after heat exchanger 4 carries out refrigeration work (absorption heat) and is converted into high temperature gas flow, and
Outdoor heat exchanger 1 is flowed back to by return duct 7.Experiment proves can be from 30 by the temperature of the refrigerant after the throttling of the first capillary 51
DEG C it is reduced to below 10 DEG C of degree, and room temperature is typically more than 20 DEG C, therefore refrigerating efficiency can be higher.
Refrigerant exits into the second capillary from indoor heat exchanger 4 (now equivalent to the outdoor heat exchanger 1 in heating work)
Pipe 52 enters outdoor heat exchanger 1 (now equivalent to the indoor heat exchanger 4 in heating work) after being throttled, due to the second capillary
The length of pipe 52 is more than the first capillary 51, therefore the refrigerant temperature of the second capillary 52 throttling can become lower, experiment card
It is bright, when the length of the second capillary 52 is twice of the first capillary 51, the temperature of refrigerant can be reduced to from 30 DEG C 0 DEG C with
Under, the refrigerant after now cooling is easier to absorb outside heat, and compressor will absorb more outside after outdoor heat exchanger 1 is entered
The refrigerant of heat is converted into high temperature gas flow, and flows to indoor heat exchanger 4 by return duct 7 and realize heat-production functions.Due to
The first check valve 511 is provided with one capillary 51, refrigerant can be avoided directly by the first capillary 51, to be not reaching to mesh
Enter outdoor heat exchanger 1 in the case of mark temperature.
This programme, can using refrigeration and the function of heating is realized by the first capillary 51 and the second capillary 52 respectively
Refrigeration or the efficiency of heating work is set to become higher.
It should be noted that in specific installation, the both ends of the second capillary 52 can directly with communicating pipe 2 and stop valve 3
Connection.Can also as shown in Figure 2, the both ends of the second capillary 52 are both connected on the first capillary 51, while single by first
The particular location being arranged on to valve 511 on the first capillary 51 is two connecting portions of the second capillary 52 and the first capillary 51
Between position, such refrigerant can be in the second capillary 52 and the first capillary of part 51 by extending restricted flow path, Jin Erti
High restriction effect.
Further, the second check valve 521 is provided with the second capillary 52, to prevent in outdoor heat exchanger 1
Refrigerant flows out through the second capillary 52.It is cold so to prevent that the second capillary 52 from flowing out to outdoor heat exchanger 1 in refrigeration work
Matchmaker is shunted, and then improves the flow velocity of refrigerant in the first capillary 51, is improved refrigerating efficiency.
To realize purpose of utility model, the utility model also provides a kind of air conditioner, including has above example above
Described in outdoor unit.
To realize purpose of utility model, the utility model on the one hand also provide a kind of refrigeration plant (can be refrigerator or its
His refrigeration plant), including heat transmission equipment, the heat transmission equipment are the outdoor unit described in above example.
It is reasonable in design that above example has the utility model, simple in construction, easy for installation, makes to vacuumize and irrigates system
The time of cryogen greatly shortens, and improves production efficiency.
Embodiment of the present utility model is the foregoing is only, is not limited to the utility model, for this area
Technical staff for, the utility model can have various modifications and variations.It is all within the spirit and principles of the utility model,
