The invention relates to a dehumidification device and a dehumidification method for an air conditioner. Especially in low-temperature and low-humidity climate conditions, it is an air-conditioning dehumidification device and dehumidification method that dehumidifies while maintaining room temperature while reducing noise. Thanks to the invention, the refrigerant discharged from the compressor is allowed to flow into the outdoor heat exchanger during cooling. During dehumidification, since the driving of the outdoor heat exchanger and the outdoor fan are stopped, it is possible to prevent the problem of aggravation of power consumption and the noise generated by the continuous driving of the outdoor fan.
Description
The present invention relates to air conditioner.The dehydrating unit and the dehumanization method that particularly relate to such air conditioner do not drive the outdoor fan that forms the noise reason in the dehumidifying of air conditioner action, only drive chamber's internal fan action that dehumidifies.
The work of general air conditioner is divided into two kinds according to circulation.
First kind mainly is in usefulness in the summer of heat, the type of cooling of using in the high office of temperature and humidity.
Second kind is to be used in the high bai-u rainy period of temperature low humidity, and indoor temperature is kept former state, only is to remove the dehumidification mode of following that humidity moves like that.
Fig. 1 is the flow chart of the cold-producing medium when being in the type of cooling in top two kinds of modes saying.Compressor reducer (1) on this figure drives, and electronic valve (8) just disconnects, and the triple valve of Chan Shenging (7) is connected downwards therefrom.Cold-producing medium by compressor reducer (1) and outdoor heat converter (2), afterwards, is depressurized on the 1st decompressor (3) in order.
At this moment, outdoor heat converter moves with condenser, and the above-mentioned cold-producing medium that has been depressurized by heat-heat exchanger (4) and triple valve (7) again, flows to indoor heat converter (5) in order again.
Indoor heat converter (5) carries out the cold-producing medium that flows into after the heat exchange, and reduction is on compressor reducer (1).
At this moment heat-heat exchanger (4) and indoor heat converter (5) become with evaporimeter and move again.
On the other hand, when dehumidification mode, it is shown in Figure 2 that cold-producing medium mobile seen.Compressor reducer (1) one closes, and electronic valve (8) closes downwards, and triple valve disconnects.The cold-producing medium of being discharged by compressor reducer (1) passes through outdoor heat converter (2).Do not had after the heat exchange, by above-mentioned electronics valve (8), flowed into again heat-heat exchanger (4) again.
At this moment, outdoor heat converter (2) has become with condenser and has worked.Heat-heat exchanger (4) also becomes with condenser and works again.
And, the cold-producing medium of discharging from heat-heat exchanger (4) again, after on second decompressor (6), having reduced pressure, through triple valve (7), inflow indoor heat exchanger (5).
After this, the cold-producing medium on the inflow indoor heat exchanger (5) after not had heat exchange, is reduced on above-mentioned compressor reducer (1).
At this moment, indoor heat converter (5) is used evaporator operation, because the driving of indoor fan (11) has become and the low-temperature refrigerant heat exchange.The air of humidity that has been removed low temperature carries out heat exchange more again being reduced on the heat-heat exchanger (4) again.When it and indoor inflow air during, discharge successfully at same state.Because like this, can dehumidify.
But, former such air-conditioning, when dehumidifying between the bai-u rainy periods that low temperature wets more, indoor temperature can not be fallen very lowly.This air-conditioning is kept the temperature of regulation on one side, Yi Bian dehumidify.At this moment, the cold-producing medium in the cold-producing medium circulation is owing to also will allow it through outdoor heat converter, and outdoor fan will be rotated further, and consumed power has just been strengthened certainly.Because the rotation of continuous outdoor fan has just had the problem that produces noise.
On the other hand, allow the air quantity of indoor fan (6), and facilitate and carry out the delayed heat conduction than the lower air of evaporating temperature of the cold-producing medium of inflow indoor heat exchanger (5) in driven at low speed.Because like this, under the occasion of, high humidity low in indoor temperature, because the conduction of present heat, in dehumidifying, indoor temperature is lowered by.Cause indoor temperature too low.So under the occasion of, high humidity low in indoor temperature, want the requirement of satisfied temperature and humidity simultaneously, it is very difficult obtaining a comfortable environment.
Main purpose of the present invention provides a kind of dehydrating unit and dehumanization method of air conditioner, can keep the weather conditions of low temperature and low humidity on the one hand, can reduce noise on the other hand, accomplishes the low humidity operation.
In order to reach the such purpose of the present invention, technological means is so a kind of desiccant cooling agent control device.I.e. cold-producing medium of discharging from the cooled compressor reducer is with its inflow outdoor heat exchanger.The cold-producing medium of being discharged by said compressor during dehumidifying allows it flow into heat-heat exchanger again, prevents the cold-producing medium inflow outdoor heat exchanger during dehumidifying.
In addition, main purpose of the present invention is to be to provide a kind of air conditioner and its method of operation.This air conditioner usually can promptly arrive suitable state to indoor temperature satisfactorily.Therefore can obtain comfortable indoor environment very soon.
To achieve the above object, air conditioner of the present invention has compressor reducer, outdoor heat converter, decompressor, in-room switch and indoor fan and outdoor fan; It is characterized in that between decompressor and indoor heat converter, being provided with heat-heat exchanger again, junction chamber outer heat-exchanger and the bypass of heat-heat exchanger (bypass) again.And has a triple valve.This valve is that to be used for regulating the cold-producing medium that is come out by outdoor heat converter be by one in following two devices: decompressor or by bypass.Between heat-heat exchanger and the indoor heat converter electric expansion valve is being set again.The invention provides the method for operation of air conditioner simultaneously, it is characterized in that with above-mentioned feature:

Fig. 6 shows the workflow diagram of Fig. 5.
Below, with reference to accompanying drawing the present invention is done a detailed explanation.
Fig. 3 and Fig. 4 adopt air conditioner structure figure of the present invention.By diagram as can be known, air conditioner is made of following several parts.
Desiccant cooling agent control section (62) is arranged.This part function is when the type of cooling, from the cold-producing medium that compressor reducer (51) is discharged, allows its inflow outdoor heat exchanger (52).And when dehumidification mode, the cold-producing medium from said compressor (51) is discharged allows it flow into heat-heat exchanger (54) again.
Outdoor heat converter (52) is arranged.This part function is to allow carry out heat exchange by the resulting cold-producing medium of above-mentioned desiccant cooling agent control part.
First decompressor (53) is arranged.This part function is to allow the cold-producing medium of discharging from above-mentioned outdoor heat converter (52) heat exchange reduce pressure.
Heat-heat exchanger (54) is arranged again.Its function is that the cold-producing medium that allows the 1st decompressor (53) reduce pressure carries out heat exchange again and discharges.
Triple valve (57) is arranged.Its function is to instruct control section (59) to remove to control cold-producing medium.This cold-producing medium is discharged by above-mentioned heat exchanger (54), reduces pressure again.From second decompressor (56), can obtain.
Have its function of indoor heat exchanger (55) be the cold-producing medium of regulating by above-mentioned triple valve after heat exchange, reduction is on said compressor (51).
Prevent that in addition outdoor fan (60), indoor fan (61) that outdoor heat converter (52), indoor heat converter (55) temperature rise from constituting.
When being shown in type of cooling operation by Fig. 3, if compressor reducer (51) drives, desiccant cooling agent control section (62) and triple valve (57) are all in off-state.
Under such state, the cold-producing medium of being discharged by compressor reducer (51) is depressurized on the 1st decompressor (53) after outdoor heat converter (52) heat exchange again.
At this moment, outdoor heat converter (52) is with condenser action, the decompression that comes from above-mentioned first decompressor (53) cold-producing medium in order by heat-heat exchanger (54) and triple valve (57) again, afterwards, on said compressor (51), be reduced again.
At this moment, heat-heat exchanger (54) and indoor heat converter (55) move with evaporimeter again.
On the other hand, when the dehumidifying operation, as on Fig. 4, compressor reducer (51) drives, and desiccant cooling agent control section (62) and triple valve (57) are all connected downwards.
So, the cold-producing medium of being discharged by said compressor (51) is because desiccant cooling agent control part (62) control flows into heat-heat exchanger (54) immediately again.
Flow into the cold-producing medium of heat-heat exchanger (54), after heat exchange was discharged, the cold-producing medium of such discharge was gone up decompression at second decompressor (56) again, through triple valve (57), and inflow indoor heat exchanger (55).
At this moment, heat-heat exchanger (54) is used condenser work again, and indoor heat converter (55) is used evaporator operation.
So, because the driving of indoor fan (61), indoor heat converter (55) and low-temperature refrigerant have become heat exchange.The air of having removed the moisture of low temperature reenters heat-heat exchanger (54) again.The cold-producing medium of HTHP is reduced on compressor reducer (51).
On the other hand, heat-heat exchanger is being obtained by above-mentioned indoor heat converter (55) there again, and the air that the moisture of high temperature has been removed carries out heat exchange again.Above-mentioned air and indoor inflow air are just discharged when same state.So just finished dehumidification function.
By above-mentioned detailed description as can be known, the present invention when the dehumidifying operation, owing to do not use outdoor heat converter, does not need outdoor fan to rotate, and can have to prevent owing to outdoor fan rotates the effect that produces noise.
Equally, the present invention is owing to prevented the outdoor fan rotation, and the tube impedance loss is little, therefore has the compressor reducer load and can reduce the effect that original power consumption can reduce.
Fig. 5 and Fig. 6 are the structure chart and the flow charts of other practice examples of the present invention.If set the design temperature Ts of expectation, just begin to start.When control section (120) starts compressor reducer (101), outdoor fan (103) and indoor fan (108) have also been started.
Compressor reducer (101) one starts, and cold-producing medium flows along the illustrated direction of arrow, and cool cycles is formed.
When the type of cooling was worked, design temperature (Ts) was at the high temperature (T of regulation
4) when above (be the practice example of Fig. 6, T
1=24 ℃), indoor temperature (T
1) reaching design temperature (Ts) before, control section (120) has been carried out the type of cooling in strong stage now so.
At this moment, the type of cooling in strong stage, the high-speed rotation of outdoor fan (103) and indoor fan (108), cold-producing medium will pass through outdoor heat converter (102), decompressor (105), heat-heat exchanger (107) again, solenoid valve (104) action, electric expansion valve (109) is in full-gear.
That is to say that cold-producing medium passes through compressor reducer (101), outdoor heat converter (102), screw pipe valve (104), decompressor (105), heat-heat exchanger (107), electric expansion valve (109), indoor heat converter (110), the also oriented compressor reducer reduction of cold-producing medium are simultaneously flowed again.
As a result, outdoor heat converter (102) is used condenser work, and heat-heat exchanger (107) and indoor heat converter (110) are all used evaporator operation again.
On the other hand, design temperature (Ts) is than the high temperature (T of regulation
1) low, and indoor temperature (T
1) than the high temperature (T that stipulates
4) the low refrigeration modes of all carrying out the strong stage before.Afterwards, the low temperature (T of design temperature (Ts) and regulation
1) compare (on Fig. 6, the actual example that uses, T=20 ℃), if design temperature (Ts) is the low temperature (T at defined
2) more than, indoor temperature (T so
1) reaching the type of cooling that design temperature (Ts) is the stage in the implementation before.
Here, be under the type of cooling in stage in so-called, the operation of indoor fan (108) middling speed, outdoor fan (103) is at middling speed or low cruise.Cold-producing medium is by outdoor heat converter (102), bypass (bypass) (106) and just action of heat-heat exchanger (107), solenoid valve (104) again.The so-called state of using electric expansion valve (109) work in the type of cooling in middle stage exactly.
Just, cold-producing medium flows through compressor reducer (101), outdoor heat converter (102), solenoid valve (104), bypass (bypass) (106), heat-heat exchanger (107), electric expansion valve (109), indoor heat converter (110) again, flows to compressor reducer (101) again.
As a result, outdoor heat converter (102) is worked with condenser.Heat-heat exchanger (107) is used another condenser again, and electric expansion valve (109) is used decompressor, and indoor heat converter (110) works with evaporimeter.
At this moment, because the driving of indoor fan (108) forms heat exchange by indoor heat converter (110) and refrigerant of low temperature, the air of having removed the low temperature moisture passes through heat-heat exchanger (107) more again, heating is discharged from again, has carried out indoor dehumidification now.
On the other hand, the temperature of setting (Ts) compare fixed low temperature (T
2) low, indoor temperature (T
1) to than fixed low temperature (T
2) low before, the type of cooling in stage in carrying out.Afterwards, indoor temperature (T
1) arrive design temperature (Ts) before, be the type of cooling of carrying out the weak stage.
Here, the type of cooling in so-called weak stage, flow of refrigerant is the same with such state in the type of cooling in middle stage.Indoor fan (108) slowly runs, and outdoor fan (103) is not that low speed is interrupted rotation.
Therefore, compare with the type of cooling in middle stage, all refrigeration plant power is little, because present heat and the remaining heat ratio that produces, the heat that causes conduction is big.Decision is kept indoor temperature on one side, Yi Bian dehumidify.
By above detailed description like that, air-conditioner of the present invention owing to do not use outdoor heat converter, there is no need drive chamber's external fan when the dehumidifying operation, therefore have can prevent because the outdoor fan rotation produces the effect of noise.
Owing to prevented the rotation of outdoor fan, the tube impedance loss is little simultaneously, therefore has the compressor reducer load and can reduce the effect that original power consumption can reduce.
And, because by the refrigerant flowpath of design temperature defined and different in the past, so indoor temperature can not descend.So just can keep on one side fixed temperature, dehumidify Yi Bian following, so the present invention has the effect of the indoor environment that can reach comfortable fast.
