Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, the present invention provide firstly a kind of constant-temperature dehumidification system, and described system comprises:
Compressor 200, condenser 100, first throttle element 500, evaporimeter and controller 800, described evaporimeter comprises heating fumigators 300 and dehumidifying evaporimeter 400, be connected by second section fluid element 600 between described heating fumigators 300 with dehumidifying evaporimeter 400, described controller 800 is connected with described second section fluid element 600 with outer blower fan, described compressor 200, described first throttle element 500, the windward side that described heating fumigators 300 is arranged at the leeward side of air-conditioning internal machine, described dehumidifying evaporimeter 400 is arranged at air-conditioning internal machine.
As shown in Figure 2, present invention also offers a kind of control method of constant-temperature dehumidification system, this method is applied to the controller 800 of the constant-temperature dehumidification system shown in Fig. 1, and this method comprises the following steps:
Step S101: obtain current first environment humidity;
Controller 800 gathers the first environment temperature of Current ambient air by humidity sensor, judges whether described first environment humidity is greater than described dehumidifying and enters humidity; When first environment humidity be greater than dehumidifying enter humidity time, then represent that the humidity in current environment is comparatively large, easily form condensation, therefore now need to dehumidify.
When described first environment humidity be not more than described dehumidifying enter humidity time, then enter normal refrigerating mode, when first environment humidity be not more than described dehumidifying enter humidity time, then show that now humidity is less in environment, not easily generate condensation, so now perform special control mode without the need to controlling air-conditioning system, perform normal refrigerating mode.
Step S102: when described first environment humidity be greater than dehumidifying enter humidity time, enter constant temperature dehumidification process, described constant temperature dehumidification process comprises the described first throttle element 500 of control and the action of described second section fluid element 600, control described condenser 100 transfer part condenser heat to described heating fumigators 300, to make surrounding air after described dehumidifying evaporimeter 400 cool-down dehumidification, flow through described heating fumigators 300 to heat up, control outer rotation speed of fan and make the cooling temperature of dehumidifying evaporimeter 400 identical with the warming temperature of heating fumigators 300;
In dehumidification process, if environment temperature is too high, the cold comfort of human body reduces, if environment temperature is too low, easily produce condensation, comprehensively above-mentioned two aspects, the present invention carries out constant temperature dehumidification to surrounding air.
Constant temperature dehumidification process is specially: in constant temperature dehumidification process, control first throttle element 500 action, the restriction effect of first throttle element 500 is almost eliminated, controlling the action of second section fluid element 600 makes refrigerant can only flow through from second section fluid element 600, now heating fumigators 300 is in HTHP side, be equivalent to second piece of condenser 100, can play the effect adding hot-air, and the evaporimeter 400 that dehumidifies is in low-pressure side, the effect of cooling, dehumidifying can be played.Owing to dehumidifying in native system, evaporimeter 400 is arranged on windward side, heating fumigators 300 is arranged on leeward side, and the processing procedure of surrounding air after interior machine becomes first cool-down dehumidification (with the heat exchange of dehumidifying evaporimeter 400), heat up (with heating fumigators 300 heat exchange) again.
Because now condenser 100, heating fumigators 300 are condensation, the wherein heat exchange amount of a piece is regulated, the heat exchange amount of second piece will be affected, the heat exchange amount that outer machine rotation speed of fan can reduce heating fumigators 300 is improved by theory analysis and experimental verification, under dehumidifying evaporimeter 400 pairs of environment temperature moisture removal and cooling measure constant prerequisite, reduce the intensification amount of heating fumigators 300 pairs of air, then can reduce environment temperature; Improve the heat exchange amount that outer machine rotation speed of fan can improve heating fumigators 300, under dehumidifying evaporimeter 400 pairs of environment temperature moisture removal and cooling measure constant prerequisite, improve the intensification amount of heating fumigators 300 pairs of air, then environment temperature can be increased, so the application in the specific implementation, raise according to environment temperature and reduce, in real time the outer rotation speed of fan of adjustment, thus keep environment temperature-resistant, realize the process of constant temperature dehumidification.
Step S103: obtain current second environment humidity, when described second environment humidity be greater than dehumidifying exit humidity time, continue to perform described constant temperature dehumidification process, until current ambient humidity is less than described dehumidifying exit humidity, wherein, described dehumidifying enters humidity and is more than or equal to described dehumidifying and exits humidity.
After a constant temperature dehumidification process, again obtain content and the second environment humidity of vaporous water molecule in air, whether judgement second environment humidity is now less than dehumidifying is exited humidity, it is the humidity value preset that humidity is exited in dehumidifying, be used for representing that now humidity is lower and not easily produce dew condensation phenomenon, humidity is exited when second environment humidity is greater than dehumidifying, prove that second environment humidity is now still larger, so need to proceed constant temperature dehumidification process, humidity is exited when second environment humidity is less than dehumidifying, then represent that now humidity is lower, not easily produce dew condensation phenomenon, constant temperature dehumidification process can be exited.
Wherein, dehumidifying enters humidity and dehumidifying, and to exit humidity can be identical humidity value, simple and convenient when realizing, certainly both also can be different humidity values, and dehumidifying enters humidity is greater than dehumidifying and exits humidity, between two kinds, there is certain psychrometric difference, can avoid frequently switching being embodied in enter constant temperature dehumidification process and exit between constant temperature dehumidification process, waste system resource.
In above-mentioned steps S102, as shown in Figure 3, the process of the outer rotation speed of fan of concrete adjustment is:
Step S201: the rotating speed of outer blower fan is reduced to preset rotation speed;
This preset rotation speed is for presetting a rotating speed, in theory under this rotating speed the warming temperature of heating fumigators 300 and the cooling temperature of initial evaporator consistent, but theoretic rotating speed is also necessarily applicable to actual conditions, so constantly adjust outer rotation speed of fan in constant temperature dehumidification process, to reach accurate Regulation of Constant Temperature.
Step S202: obtain current first environment temperature, and the size of more described first environment temperature and preset temperature;
In constant temperature dehumidification process, first environment temperature is gathered by temperature sensor, and first environment temperature should be contrasted by holding temperature i.e. (preset temperature) with in Regulation of Constant Temperature, if consistent, without the need to adjusting outer rotation speed of fan, if inconsistent, external rotation speed of fan is needed to adjust.
Step S203: when described first environment temperature is greater than preset temperature, improve the rotating speed of described outer blower fan, when described first environment temperature is less than described preset temperature, reduces the rotating speed of described outer blower fan.
When first environment temperature is greater than preset temperature, prove that the warming temperature of heating fumigators 300 is higher, so now improve outer rotation speed of fan, reduce the heat dissipation capacity of heating fumigators 300, to make the heat dissipation capacity of heating fumigators 300 reduce, so that it is constant to maintain environment temperature.
When first environment temperature is less than preset temperature, prove that the warming temperature of heating fumigators 300 is lower, so now reduce outer rotation speed of fan, improve the heat dissipation capacity of heating fumigators 300, to make the heat dissipation capacity of heating fumigators 300 improve, so that it is constant to maintain environment temperature.
Introduce specific embodiments of the invention below, as shown in Figure 4, the present invention provides a kind of thermostatic control system, and wherein said first throttle element 500 is expansion valve, and described second section fluid element 600 is choke valve and the capillary in parallel with choke valve.
Below in conjunction with the system shown in Fig. 4, constant temperature dehumidification process of the present invention is described in detail:
Air-conditioning internal machine evaporimeter divide into two parts: heating fumigators 300 and dehumidifying evaporimeter 400, and has the intermediary agency of choke valve 601 parallel capillary tube 602 between heating fumigators 300 and dehumidifying evaporimeter 400.
When entering constant temperature dehumidification process, controller 800 controls expansion valve 500 standard-sized sheet, its restriction effect is almost eliminated, controller 800 controls choke valve 601 coil and obtains the electric choke valve 601 that makes and cut out, thus refrigerant can only be flow through from the capillary 602 in parallel with choke valve 601, and now heating fumigators 300 is in HTHP side, be equivalent to second piece of condenser 100, can play the effect adding hot-air, and the evaporimeter 400 that dehumidifies is in low-pressure side, the effect of cooling, dehumidifying can be played.When building native system, dehumidifying evaporimeter 400 is arranged on windward side, heating fumigators 300 is at leeward side, namely the air in environment is first and dehumidifying evaporimeter 400 heat exchange through interior machine, again with heating fumigators 300, thus make the processing procedure of air after interior machine become first cool-down dehumidification (with the heat exchange of dehumidifying evaporimeter 400), then heat up (with heating fumigators 300 heat exchange).
The environment temperature of air is first lowered the temperature, is heated up, and in order to realize constant temperature dehumidification process, the present invention adopts and regulates the rotating speed of off-premises station blower fan 700 to keep the environment temperature of air constant.Because condenser 100, heating fumigators 300 are condensation in constant temperature dehumidification process, so regulate the wherein heat exchange amount of a piece, the heat exchange amount of second piece will be affected, namely regulate the heat exchange amount of condenser 100 can affect the heat exchange amount of heating fumigators 300.
Through present inventor by theory analysis and experimental verification, the rotating speed finding to improve outer blower fan 700 can reduce the heat exchange amount of heating fumigators 300, and then reduce the intensification amount of heating fumigators 300 pairs of air, under dehumidifying evaporimeter 400 pairs of environment temperature moisture removal and cooling measure constant prerequisite, and then reduce environment temperature; In like manner, the rotating speed reducing outer blower fan 700 can improve the heat exchange amount of heating fumigators 300, and then improve the intensification amount of heating fumigators 300 pairs of air, under constant prerequisite is measured in dehumidifying evaporimeter 400 pairs of environment temperature moisture removal, cooling, and then improve environment temperature.
So in dehumidification process, when environment temperature is lower than thermostat temperature, then reduce the rotating speed of outer blower fan 700, when environment temperature is higher than thermostat temperature, then improve the rotating speed of outer blower fan 700, thus by detected temperatures and the outer rotation speed of fan of adjustment, the moment makes air-conditioning be in constant temperature dehumidification state.
The present invention is after ambient humidity is comparatively large, just the control of constant temperature dehumidification is entered into, the requirement of dehumidifying can be met, simultaneously because leaving air temp is higher, ensure that the place such as panel, air port cannot reach the dew-point temperature of surrounding air, make vaporous water molecule in environment cannot condensation, fundamentally avoid the possibility of condensation, although go out environment temperature to remain unchanged in constant temperature dehumidification process, but because air-conditioning is still in dehumidifying, relative humidity reduces the comfort of human body and remains lifting, thus solves condensation problem and improve human comfort simultaneously.
In constant temperature dehumidification process, consider the refrigeration demand of user, so the present invention also add following content on the basis of the method shown in Fig. 2, as shown in Figure 5, comprising:
Step S301: obtain current second environment temperature;
Step S302: judge whether described second environment temperature is greater than preset comfort temperature;
Preset comfort temperature is the temperature value preset, for representing the boundary of user awareness comfort level, when the first environment temperature of surrounding air is greater than preset comfort temperature, then represent that users'comfort is poor, in order to improve human comfort, need to carry out suitable refrigeration, when the first environment temperature of surrounding air is less than preset comfort temperature, then represent that users'comfort is better.
Step S303: enter process of refrigerastion when described second environment temperature is greater than described preset comfort temperature;
Step S304: the 3rd ambient humidity that Real-time Collection is current;
Due to the effect reducing ambient humidity, so it is normal humidity in air likely to be made to return by process of refrigerastion when humidity is little in atmosphere, so after process of refrigerastion is complete, the 3rd ambient humidity of environment can be obtained while process of refrigerastion.
Step S305: judge whether described 3rd ambient humidity is greater than dehumidifying and exits humidity, if be greater than, enters step S307, if be less than, enters step S306;
Step S306: when described 3rd ambient humidity be less than dehumidifying exit humidity time, enter normal refrigerating mode.
If the 3rd ambient humidity is less than dehumidifying when exiting humidity, then without the need to carrying out constant temperature dehumidification process, directly carry out normal process of refrigerastion, if the 3rd ambient humidity is greater than dehumidifying when exiting humidity, prove that now the 3rd ambient humidity is still higher, needs to enter constant temperature dehumidification process and dehumidifies.
Step S307: directly enter described constant temperature dehumidification process when described second environment temperature is not more than described preset comfort temperature.
When first environment temperature is not more than preset comfort temperature, illustrate that environment temperature is now in human body humidity range, so now only carry out constant temperature dehumidification to current first environment temperature.
A period of time is run to reduce environment temperature by controlling compressor 200 high frequency at refrigeration Time Controller 800, the frequency that compressor 200 runs is higher, and to represent its refrigeration dynamics larger, the humidity of environment can be reduced while refrigeration, so after refrigeration terminates, verify whether the 3rd current ambient humidity is greater than dehumidifying and exits humidity, when described 3rd ambient humidity be not more than dehumidifying exit humidity time, just illustrate that the process of the same double dehumidifying of refrigeration just can reach dehumidification requirements, so can normal refrigerating mode be entered, when the 3rd ambient humidity be greater than dehumidifying exit humidity time, illustrate that the dynamics dehumidified in process of refrigerastion is less, need again to carry out special dehumidification process, namely described constant temperature dehumidification process is entered.
Compressor 200 high frequency controlling air-conditioning in above-mentioned steps S303 runs the step reducing current environment temperature, specifically when performing, and can by following two kinds of modes:
As shown in Figure 6, first kind of way comprises the following steps:
Step S401: compressor 200 high frequency controlling air-conditioning runs;
Step S402: the 3rd environment temperature that Real-time Collection is current;
Step S403: judge whether described 3rd environment temperature is greater than described preset comfort temperature; If be greater than, enter step S401, if be less than, enter step S404;
Step S404: enter normal refrigerating mode.
The core thinking of first kind of way is that compressor 200 high frequency controlling air-conditioning runs the 3rd environment temperature that also Real-time Collection is current, until described 3rd environment temperature is not more than described preset comfort temperature, namely continue to freeze to surrounding environment, until ambient temperature reaches the comparatively comfortable temperature of human body.
The second: control compressor of air conditioner 200 high frequency and run Preset Time.
Preset Time is the time value preset, and after being used for representing that compressor of air conditioner 200 high frequency runs this Preset Time, just can reach the comparatively comfortable temperature of human body, Preset Time can be determined according to concrete condition, in this no limit.
The refrigeration demand of user is considered in the process of constant temperature dehumidification, environmentally temperature and ambient humidity judge surrounding environment, if refrigeration demand is comparatively large, powerful refrigeration a period of time, because air-conditioning while refrigeration is still in dehumidifying, so cooling, dehumidifying can be taken into account, and realizing known for a long time according to technical staff, the refrigeration in the short time can not cause condensation consequence.
As shown in Figure 1, the invention provides a kind of control system anti-condensation in advance, comprising:
Compressor 200, condenser 100, first throttle element 500, evaporimeter and controller 800, wherein, described evaporimeter comprises heating fumigators 300 and dehumidifying evaporimeter 400, be connected by second section fluid element 600 between described heating fumigators 300 with dehumidifying evaporimeter 400, described controller 800 is connected with described second section fluid element 600 with outer blower fan, described compressor 200, described first throttle element 500;
Described controller 800 is for performing processing procedure anti-condensation in advance, and described processing procedure anti-condensation in advance specifically comprises: obtain current first environment humidity; When described first environment humidity be greater than dehumidifying enter humidity time, enter constant temperature dehumidification process; Described constant temperature dehumidification process comprises the described first throttle element 500 of control and the action of described second section fluid element 600, control described condenser 100 transfer part condenser heat to described heating fumigators 300, to make surrounding air after described dehumidifying evaporimeter 400 cool-down dehumidification, flow through described heating fumigators 300 to heat up, control outer rotation speed of fan and make the cooling temperature of dehumidifying evaporimeter 400 identical with the warming temperature of heating fumigators 300; Obtain current second environment humidity, when described second environment humidity be greater than dehumidifying exit humidity time, continue perform described constant temperature dehumidification process, until current ambient humidity is less than described dehumidifying exit humidity, wherein, described dehumidifying enters humidity and is more than or equal to described dehumidifying and exits humidity.
Described processing procedure anti-condensation in advance also comprises:
Obtain current second environment temperature, and judge whether described second environment temperature is greater than preset comfort temperature; Enter process of refrigerastion when described second environment temperature is greater than described preset comfort temperature, directly enter described constant temperature dehumidification process when described second environment temperature is not more than described preset comfort temperature.
The invention provides a kind of constant-temperature dehumidification system, the present invention enters constant temperature dehumidification process when ambient humidity is larger, specific implementation is: first throttle element 500 action in constant temperature dehumidification process, its restriction effect is almost eliminated, second section fluid element 600 action makes refrigerant can only flow through from second section fluid element 600, now heating fumigators 300 is in HTHP side, be equivalent to second piece of condenser 100, the effect adding hot-air can be played, and the evaporimeter 400 that dehumidifies is in low-pressure side, the effect of cooling, dehumidifying can be played.Because dehumidifying evaporimeter 400 is arranged on windward side, heating fumigators 300 is arranged on leeward side, and the processing procedure of air after interior machine becomes first cool-down dehumidification (with the heat exchange of dehumidifying evaporimeter 400), heat up (with heating fumigators 300 heat exchange) again.
