Embodiment
The preferred embodiment of the present invention described with reference to the accompanying drawings.It will be apparent to a skilled person that this
A little embodiments are used only for explaining the technical principle of the present invention, it is not intended that limit the scope of the invention.
As shown in figure 1, the air conditioner cooling cycle system of the present invention includes being connected on the compressor 1 of major loop, indoor heat exchange
Device 2, first throttle device 3 and outdoor heat exchanger 4.Wherein, bypass circulation N is provided between major loop and compressor 1；From interior
A part of refrigerant that heat exchanger 2 flows out flows into bypass circulation N, and another part flows along major loop.
Specifically, when heating circular flow, the high pressure gaseous refrigerant that compressor 1 is discharged reaches indoor heat exchanger
2 (being now condenser) carry out heat exchange, are changed into the liquid refrigerants of medium temperature high pressure, and the liquid refrigerants of medium temperature high pressure arrives along major loop
Up to A points, now, refrigerant circulation is divided into two-way, and a curb major loop continues to flow, and another way flows into bypass circulation N.
In the present embodiment, bypass circulation N is provided with second throttling device 5, and it is used to control into the cold of bypass circulation N
Matchmaker measures.Specifically, gas-liquid mixed liquid of the medium temperature high-pressure liquid refrigerant of A points through the formation low-temp low-pressure of second throttling device 5 is cold
Matchmaker.
In the present embodiment, heating recycle system also includes heat exchanger 6, and major loop and bypass circulation N pass through the heat
Exchanger 6.Specifically, by the major loop of heat exchanger 6 be positioned at indoor heat exchanger 2 export (being specially the A points in Fig. 1) with
Section between first throttle device 3；Bypass circulation N by heat exchanger 6 is positioned at compressor 1 and second throttling device 5
Between section.That is, when heating circular flow, the liquid refrigerants of medium temperature high pressure is divided into two-way in A points, all the way successively
Through 3 → outdoor heat exchanger of over-heat-exchanger 6 → first throttle device 4；Another way passes through 5 → heat exchange of second throttling device successively
6 → compressor of device 1.
Heat exchanger 6 is used to make the refrigerant in the refrigerant and major loop in bypass circulation N be exchanged heat.So, it is other
The gas-liquid mixed state refrigerant of the low-temp low-pressure formed in logical loop N by second throttling device 5, with major loop without first
The liquid refrigerants of the medium temperature high pressure of throttling arrangement 3, it can be exchanged heat by heat exchange 6.For example, heat exchanger 6 can be one
The individual water tank (heat exchanger 6 can also be the form of other any suitables, and water tank is merely illustrative) for filling water, from interior
The medium temperature high-pressure liquid refrigerant that heat exchanger 2 flows out changes with the water in heat exchanger 6 first before by first throttle device 3
Heat, equally handed over when the gas-liquid mixed state refrigerant of the low-temp low-pressure formed through second throttling device 5 flows in bypass circulation N with heat
The water changed in 6 is exchanged heat.Also it is equivalent to, the medium temperature high pressure liquid of gas-liquid mixed state refrigerant and major loop in bypass circulation N
State refrigerant carries out heat exchange.
Gas-liquid mixed state refrigerant in bypass circulation N and the medium temperature high pressure in major loop are realized by above-mentioned heat exchanger 6
Liquid refrigerants is exchanged heat, and on the one hand can be effectively increased system super cooled sect, i.e. point A to the segmented portion of first throttle device 3
Refrigerant can continue to heat release cooling；On the other hand, the medium temperature high-pressure liquid refrigerant flowed out from indoor heat exchanger 2 divides two-way to be steamed
Hair heat absorption, i.e., at first throttle device 3 and at second throttling device 5, so equivalent to the disengagement area for adding refrigerant, so that
Effectively improve the exchange capability of heat of system.
More specifically, the low-temp low-pressure liquid state refrigerant in bypass circulation N returns after heat exchanger 6 absorbs heat of vaporization
It flow to the gas returning port of compressor 1；Medium temperature high-pressure liquid refrigerant in major loop is after heat exchanger 6 releases heat, then through first
Throttling arrangement 3 formed low-temp low-pressure gas-liquid mixed state refrigerant, into outdoor heat exchanger 4 carry out heat exchange, after be back to compression
The gas returning port of machine 1.
Preferably, compressor 1 is provided with gas-liquid separator 11, no matter from bypass circulation N or major loop enters compressor 1
Gaseous coolant first pass around the gas-liquid separator 11 after, then sucked by compressor 1, so as to open subsequent cycle.
In summary, heating recycle system of the invention is by making the refrigerant in the refrigerant and major loop in bypass circulation N
Exchanged heat, on the one hand can be effectively increased system super cooled sect, i.e. the refrigerant of point A to the segmented portion of first throttle device 3 can
Continue heat release cooling；On the other hand, the medium temperature high-pressure liquid refrigerant flowed out from indoor heat exchanger 2 divides two-way to be evaporated heat absorption,
I.e. at first throttle device 3 and at second throttling device 5, so equivalent to the disengagement area for adding refrigerant, so as to effectively carry
The exchange capability of heat of system is risen.
Present invention also offers a kind of air conditioner, the air conditioner be provided with it is above-mentioned in the air-conditioning heating circulatory system.It is above-mentioned
The purpose of heating recycle system is to strengthen heating capacity, heats required more refrigerants according to ultralow temperature and carries out filling accounting, increases
The mass flow and heat exchange amount during thermal cycle are added, and the air conditioner of the present invention may be used also after above-mentioned heating recycle system is installed
To set four-way valve to realize switching of the air conditioner between kind of refrigeration cycle and heating circulation.
Specifically, reference picture 2, Fig. 2 are a kind of structural representations of the air conditioner of the present invention.As shown in Fig. 2 in this reality
Apply in example, air conditioner include it is above-mentioned in heating recycle system (referring in particular to described above, will not be repeated here), and four-way
Valve 7.Air conditioner can realize the switching of refrigeration mode and heating mode by four-way valve 7, show that four-way valve 7 switches in Fig. 2
For kind of refrigeration cycle.In air conditioner refrigerating operaton, second throttling device 5 can be closed.
Preferably, with continued reference to Fig. 2, the bypass that air conditioner also includes being arranged between compressor 1 and outdoor heat exchanger 4 is removed
White loop M, bypass defrosting loop M are provided with the 3rd throttling arrangement 8.When refrigerating/heating is run, the 3rd throttling arrangement 8 is closed
It is not involved in refrigerating/heating circulation.When needing defrosting in heating operations, the 3rd throttling arrangement 8 is opened, what compressor 1 was discharged
HTHP refrigerant divides two-way, gets in heat exchanger 2 all the way and carries out heat exchange, heat is brought to interior；Another way passes through
The outdoor heat exchanger 4 that one throttling arrangement 8 enters frosting is defrosted, this ensure that the continuous operation of heating.
So far, combined preferred embodiment shown in the drawings describes technical scheme, still, this area
Technical staff is it is easily understood that protection scope of the present invention is expressly not limited to these embodiments.Without departing from this
