Abstract
The invention discloses an air conditioner heat exchange system and an air conditioner comprising the same. The air conditioner heat exchange system comprises a distributor and a heat exchanger consisting of multiple heat exchange units, wherein the distributor is provided with multiple flow splitting holes in one-to-one correspondence and communicated with the heat exchange units; and a throttle valve is arranged between each flow splitting hole and the corresponding heat exchange unit. According to the heat exchange system disclosed by the invention, as the throttle valves are arranged between the heat exchange units and the flow splitting holes of the distributor, by adjusting the throttling aperture of the throttle valves according to the different heat exchange efficiencies of the heat exchange units, the refrigerant of corresponding flow is enabled to pass through the heat exchange units, and the heat exchange efficiency can be maximized.
Description
Technical field
The present invention relates to the air-conditioning technical field of heat exchange, relate in particular to a kind of air-conditioning heat-exchange system and comprise its air-conditioning.
Background technology
Present air-conditioning system is that throttling element and distribution member are separately used, in most cases, throttle part is at off-premises station, and is an independent stream throttling basically, fluid after the throttling enters separate system again, by separate system fluid is assigned in each heat exchange unit of heat exchanger.
There are the following problems for existing heat-exchange system: at first, distributor front end import majority is the fluid that gas phase and liquid phase are mixed, because layering can appear in gravity effect, causes the fluid maldistribution, finally causes the heat exchanger heat exchange efficiency lower.Secondly, the design of distributor need reach corresponding uniformity, stability and repeatable requirement, causes manufacturing cost higher.At last, all at present distributors are all according to even shunting design, but heat exchanger is actually uneven to flow requirements.Existing air-condition heat exchanger shape is various, and it normally cooperates with fan realizes heat exchange function, and each heat exchange unit air quantity on the heat exchanger is inequality, so the heat exchange of each heat exchange unit load is also different.
Because the inhomogeneities of heat exchange unit, prior art personnel are often by adjusting the purpose that the tube side formula reaches uniform heat exchange of walking of heat exchange unit, not only workload is very big, nor can reach fully evenly, and heat exchanger generally can only be brought into play 90～95% heat exchange efficiency.
Summary of the invention
The invention provides a kind of air-conditioning heat-exchange system, solved existing air-conditioning heat-exchange system because the distributor distributing fluids is even, and the required fluid of each heat exchange unit of heat exchanger is inhomogeneous, finally causes the lower problem of heat exchange efficiency.
A kind of air-conditioning heat-exchange system, comprise distributor and the heat exchanger of forming by some heat exchange units, described distributor is provided with the tap hole that some and heat exchange unit are corresponding one by one and be communicated with, and is provided with choke valve between described each tap hole and the heat exchange unit corresponding with it.
Described distributor comprises distributing pipe, and tap hole is arranged on the tube wall of distributing pipe, and choke valve is fixed on the distributing pipe.
Described choke valve is the fixation type throttle valve or is unidirectional recreation room choke valve.
A kind of air-conditioning comprises compressor, the outdoor heat exchange series indoor heat-exchange system of unifying, and described indoor heat-exchange system, outdoor heat-exchange system or their both structures are:
Comprise distributor and the heat exchanger of being made up of some heat exchange units, described distributor is provided with the tap hole that some and heat exchange unit are corresponding one by one and be communicated with, and is provided with choke valve between described each tap hole and the heat exchange unit corresponding with it.
The pipeline that described outdoor heat exchange series is unified between the indoor heat-exchange system is provided with throttling element, this throttling element is born a part of throttling action or is not played throttling action, distributor of the present invention plays other a part of throttling action, because the adaptability difference of different type of machines, the most of situation of dispensing arrangement is welded on the heat exchanger, in case determine seldom to adjust, and different type of machines has difference a little to the demand of overall throttling, adjust whole restriction effect so need this throttling element, by adjusting the throttle diameter of throttling element, can adjust the throttling ratio between distributor and the throttling element, be that only throttling element or distributor play restriction effect under the extreme case.
Heat-exchange system of the present invention is arranged on choke valve between heat exchange unit and the distributor tap hole, therefore can be according to the heat exchange efficiency difference of heat exchange unit, by adjusting the throttle diameter of choke valve, allow the refrigerant of corresponding discharge pass through heat exchange unit, can be so that the heat exchange efficiency maximization.
Air-conditioning of the present invention has been removed traditional throttling element, by the choke valve on the heat-exchange system refrigerant is carried out throttling, owing to can adjust the aperture of choke valve, so refrigerant can be realized distribution according to need.

The specific embodiment
As shown in Figure 1, a kind of distributor of air-conditioning heat exchange medium, this distributor comprises distributing pipe 11, distributing pipe 11 1 ends are entrance point, other end sealing, tube wall is provided with some tap holes, and each tap hole place is welded with a choke valve 12.This choke valve can be unidirectional movable choke valve or fixation type throttle valve.
As shown in Figures 2 and 3, a kind of unidirectional movable choke valve, the valve body 100 that comprises tubulose, be provided with valve seat 111 in the valve body 100, the opening 115 and the slideway 114 that have dead in line on the valve seat 111 and be interconnected are provided with movably tape spool to the spool 112 of aperture 116 in the slideway 114, spool 112 and slideway 114 inner chamber interference fits, and an end sphere fitted seal that is connected opening 115 with slideway 114 can certainly be that the linear sealing of other shape cooperates, as the conical surface etc.Slideway 114 is provided with pod apertures 118 near the sidewall of openings 115, leaves the gap that is communicated with pod apertures 118 between valve seat 111 outer walls at slideway 114 places and the valve interior wall.Slideway 114 is away from the radially reducing of an end of opening 115, spool 112 carried out spacing, prevents that it from deviating from.
