Description
Technical field
The utility model relates to field of Refrigeration and Air-conditioning, particularly a kind of wide voltage air-conditioner.
Background technology
Along with constant development of economy, air-conditioning is widely used in residential houses, commercial building.At present the throttling arrangement that adopts of family expenses fixed frequency air conditioner device generally is single capillary, the voltage range that this air-conditioning can operate as normal general only at 187V between the 242V.If brownout or overtension, the air-conditioner cisco unity malfunction influences cooling or heating effect.Particularly under the relative very high situation of outdoor temperature in summer, be easy to cause the stoppage protection of air-conditioning, and then influenced the refrigeration of air-conditioning.In order to widen the voltage range of air-conditioner work, just need to regulate refrigerant flow.What have in the market that the throttling arrangement of part air-conditioning adopts is the structure that capillary and electric expansion valve are connected in parallel, though this can regulate refrigerant flow within the specific limits, but costing an arm and a leg and the difficult grasp of control method of electric expansion valve is so be difficult for promoting.
Summary of the invention
The purpose of this utility model is to provide a kind of wide voltage air-conditioner, this air-conditioner can be in than wide-voltage range operate as normal, guaranteed the stability of air-conditioning work.This air-conditioner comprises indoor unit and outdoor unit, and on the basis of original system architecture, throttling arrangement adopts at least two capillary parallelings to connect, and other capillaries except are connected with the by-pass governing switch separately.When overtension, compressor exhaust temperature raises; When brownout, the operation of air conditioner current value increases.After in case wherein any one value surpasses setting value, the by-pass governing switch opens, all there is cold-producing medium to flow through in a plurality of capillaries, increased refrigerant flow, so just can reduce the electric current of compressor exhaust temperature or operation of air conditioner rapidly, thereby guarantee air-conditioner operate as normal under too high or too low voltage.After voltage recovered normally, the delivery temperature of compressor and operation of air conditioner electric current all were reduced in the setting value, and the by-pass governing switch cuts out, and air-conditioner can recover normal operation again.
The purpose of this utility model is achieved in that and comprises indoor unit and outdoor unit, indoor unit comprises indoor heat converter, outdoor unit comprises compressor, gas-liquid separator, cross valve, outdoor heat converter, throttling arrangement, each assembly connects to form complete loop by pipeline, blast pipe place at compressor is provided with temperature sensing device, described throttling arrangement is connected by at least two capillary parallelings, and other capillaries except are connected with the by-pass governing switch separately.
Its second is characterised in that: the indoor heat converter place at indoor unit is provided with central controller, be provided with current sensing means in the described central controller, described central controller is connected with temperature sensing device, by-pass governing switch by holding wire.
The utility model has the advantages that: (one), guaranteed that air conditioner can operate as normal in than wide-voltage range; (2), guaranteed whole air-conditioning unit reliability of operation; (3), to add the element cost in original system lower, control method is simple, is easy to promote the use of.
Description of drawings
Fig. 1 is among the utility model embodiment one, the schematic diagram that each system component connects.
The specific embodiment
Embodiment one:
As shown in Figure 1, whole circulation system is made up of indoor unit (A) and outdoor unit (B).Indoor unit (A) comprises indoor heat converter 1, outdoor unit (B) comprises compressor 2, gas-liquid separator 3, cross valve 4, outdoor heat converter 5, throttling arrangement 6, each assembly connects to form complete loop by pipeline, wherein is provided with temperature sensing device 7 at the blast pipe place of compressor 2.Throttling arrangement 6 is connected in parallel by two capillaries 8 in the present embodiment, and one of them is connected with by-pass governing switch 9.
1 place is provided with central controller 10 at indoor heat converter, and current sensing means 11 is arranged in the central controller 10, and central controller 10 is connected with temperature sensing device 7, by-pass governing switch 9 by holding wire 12.
When air-conditioner freezes, the cold-producing medium of 2 pairs of suctions of compressor compresses, the steam of the HTHP that produces enters into outdoor heat converter 5 by cross valve 4, after carrying out heat exchange with outside air, cold-producing medium becomes highly pressurised liquid, through throttling arrangement 6 throttlings, at this moment throttling arrangement 6 is single capillary 8.The cold-producing medium of low-temp low-pressure enters indoor heat converter 1 and room air carries out heat exchange after the throttling, enters into compressor 2 by cross valve 4 through gas-liquid separator 3 through the cold-producing medium after the heat exchange, circulates next time.
Air-conditioner is in the process of work, current sensing means 11 in the temperature sensing device 7 at compressor 2 blast pipe places and the central controller 10 detects in real time to the delivery temperature and the operation of air conditioner electric current of compressor 2 respectively, detected data are passed to central controller 10, and central controller 10 compares data and the setting value of receiving.When overtension, the delivery temperature of compressor will raise; When brownout, the current value of operation of air conditioner will increase.After as long as wherein any one value has surpassed setting value, central controller 10 will be opened by-pass governing switch 9 by holding wire 12, at this moment throttling arrangement 6 is the state of two capillary 8 parallel connections, can strengthen refrigerant flow, thereby can reduce the delivery temperature or the operation of air conditioner electric current of compressor 2, guarantee the normal operation of air-conditioning under too high or too low voltage.After voltage recovered normally, the delivery temperature of compressor 2 and operation of air conditioner current value all were reduced in the setting value, and central controller 10 cuts out by-pass governing switch 9 by holding wire 12, and air-conditioner recovers operate as normal.
When air-conditioner heats, the cold-producing medium of 2 pairs of suctions of compressor compresses, the steam of the HTHP that produces enters into indoor heat converter 1 by cross valve 4, after carrying out heat exchange with room air, cold-producing medium becomes highly pressurised liquid, through throttling arrangement 6 throttlings, at this moment throttling arrangement 6 is single capillary 8.Cold-producing medium inlet chamber outer heat-exchanger 5 and outdoor air after the throttling carry out heat exchange, enter into compressor 2 by cross valve 4 through gas-liquid separator 3 through the cold-producing medium after the heat exchange, circulate next time.
Air-conditioner is in the process of work, current sensing means 11 in the temperature sensing device 7 at compressor 2 blast pipe places and the central controller 10 detects in real time to the delivery temperature and the operation of air conditioner electric current of compressor 2 respectively, detected data are passed to central controller 10, and central controller 10 compares data and the setting value of receiving.When overtension, the delivery temperature of compressor will raise; When brownout, the current value of operation of air conditioner will increase.After as long as wherein any one value has surpassed setting value, central controller 10 will be opened by-pass governing switch 9 by holding wire 12, at this moment throttling arrangement 6 is the state of two capillary 8 parallel connections, can strengthen refrigerant flow, thereby can reduce the delivery temperature or the operation of air conditioner electric current of compressor 2, guarantee the normal operation of air-conditioning under too high or too low voltage.After voltage recovered normally, the delivery temperature of compressor 2 and operation of air conditioner current value all were reduced in the setting value, and central controller 10 cuts out by-pass governing switch 9 by holding wire 12, and air-conditioner recovers operate as normal.
