It quickly exchanges heat in phase, the purpose that long-term interior outlet air is soft.
It is further to note that air is at different temperatures different the saturation degree of vapor, high-temperature gas
Usual humidity is big, and the usual humidity of cryogenic gas is small, and air-conditioning is easy to form condensed water on heat exchanger 2 in refrigeration.Likewise,
Due to the setting in the first air duct 11, the second air duct 12, the air of two bursts of different temperatures is when crossing in ceiling machine 100, hot-air
In vapor because to the cold condensation form condensed water.If condensed water does not make any processing, ceiling machine 100 in use can
The phenomenon that dripping, or there is the phenomenon that air-conditioning is sprayed water outward.Wherein, since 2 position of heat exchanger is fixed, when heat exchange
On device 2 formed condensed water when be easily processed, but when in ceiling machine 100 hot and cold air cross generate condensed water when, at air
In flow regime, easily collecting does not exclude resulting condensed water.
And it can be reduced at the second air inlet 102 when the temperature difference is larger according to inlet air temperature, leaving air temp in the application
Air inlet ratio, reduce hot and cold air the case where crossing in ceiling machine 100, can also reduce the production that crosses because air is cold and hot in this way
Raw condensed water.When the temperature difference is smaller, increase the air inlet ratio at the second air inlet 102, ensures that outlet air is soft.
Here, incoming air area control piece 7 can only control the incoming air area of the first air inlet 101, can also only control
The incoming air area of two air inlets 102 can also control the incoming air area of the first air inlet 101, the second air inlet 102 simultaneously.Under
Text illustrates so that incoming air area control piece 7 can control the incoming air area of the first air inlet 101, the second air inlet 102 respectively as an example, into
The structure of wind area control part 7 can be blinds, can also be sliding door, retractable door, rolling screen door etc., be not restricted here.
In the embodiment of the present invention propose ceiling machine 100 on be arranged dehumidification device 9, dehumidification device 9 for reducing from second into
The relative humidity for the air that air port 102 enters.That is, dehumidification device 9 is for removing the sky entered from the second air inlet 102
Steam in gas makes the reduction of its humidity.
Ceiling machine 100 according to the ... of the embodiment of the present invention is made by the way that the first air duct 11 and the second air duct 12 is arranged through heat exchange
Outlet air after air is mixed with the air without heat exchange, outlet air is softer, is also beneficial to increase air output.By inlet air temperature,
The temperature difference of leaving air temp controls incoming air area, to using through heat exchange in temperature difference adjustment ceiling machine 100 air with without changing
The air inlet ratio of the air of heat improves the comfort that ceiling machine uses, and is also beneficial to solve cold wind and hot wind in ceiling machine
The problem of condensation, easily occurs for mixing.By the way that dehumidification device 9 is arranged, condensation problem is further solved.
In embodiments of the present invention, the position of air inlet test section 81 is very flexible, and air inlet test section 81 can be located at first
At air inlet 101, either enters the wind test section 81 and be located at the second air inlet 102 or the first air inlet 101 and the second air inlet
Air inlet test section 81 is respectively equipped at 102.
Optionally, air inlet test section 81 is multiple, and multiple air inlet test sections 81 detect that the average value of temperature is into wind-warm syndrome
Degree, the inlet air temperature detected in this way are more accurate.
In some embodiments, outlet air test section 82 is located at air outlet 103, is arranged so fairly simple.Optionally, go out
Wind test section 82 is multiple, and multiple outlet air test sections 82 detect that the average value of temperature is leaving air temp.What is detected in this way goes out
Air temperature is more accurate.
In some embodiments, when the temperature difference be more than the first preset temperature when, incoming air area control piece 7 completely close second into
Air port 102；When the temperature difference is less than or equal to the first preset temperature, incoming air area control piece 7 opens the second air inlet 102.In the reality
It applies in example, thoroughly closes when the temperature difference between inlet air temperature and leaving air temp is larger, at the second air inlet 102 and no longer enter the wind,
Ensure that the wind of the blowout of ceiling machine 100 is all the air after heat exchange, indoor people can be allowed obviously to experience sendible temperature in this way
Variation.Optionally, the first preset temperature is more than 10 degree, preferably 15 degree.
In some embodiments, when the temperature difference be less than or equal to the first preset temperature and more than the second preset temperature when, second into
It is entered the wind with the first preset area in air port 102；When the temperature difference is less than or equal to the second preset temperature, the second air inlet 102 is pre- with second
If area is entered the wind, the first preset area is less than the second preset area.It is different that the second air inlet 10 is controlled by the different temperature difference
Incoming air area, to make 102 incoming air area of the second air inlet at least there are two adjust automatically shelves, control is more accurate.
Specifically, the first preset temperature is more than the second preset temperature.Optionally, the first preset temperature is more than 10 degree, preferably
15 degree.Optionally, the second preset temperature is more than 6 degree, and still optionally further, the second preset temperature is 8 degree.
Specifically, the second preset area is less than or equal to the maximum incoming air area of the second air inlet 102.Optionally, first is pre-
If area is less than or equal to the 1/2 of the maximum incoming air area of the second air inlet 102, still optionally further, the first preset area is equal to
The 1/3 of the maximum incoming air area of second air inlet 102.Optionally, the second preset area is the maximum air inlet of the second air inlet 102
The 80%-100% of area.
Specifically, after the booting of ceiling machine 100, when detecting that the temperature difference is more than the first preset temperature, the second air inlet 102
It completely closes；When detecting that the temperature difference is less than or equal to the first preset temperature, the second air inlet 102 is opened and with the first preset area
Air inlet；
After the second air inlet 102 is initially opened and continues the first preset time, if the temperature difference is more than the second preset temperature,
Second air inlet 102 keeps entering the wind with the first preset area, if the temperature difference is less than or equal to the second preset temperature, the second air inlet
102 adjust to the second preset area air inlet.
That is, between detecting twice, certain interval of time (i.e. the first preset time) is filled to ceiling machine 100 in this way
The operation heat-exchange time divided, ensures the stability of air-conditioning work.Optionally, the first preset time was more than or equal to 15 minutes, preferentially
Ground, the first preset time are 20 minutes.
More specifically, the second air inlet 102 is closed when ceiling machine 100 is just switched on, it is switched in ceiling machine 100
And after running the second preset time, incoming air area control piece 7 controls the second air inlet according to the temperature difference that temperature detection part 8 detects
102 incoming air area.It is understood that when ceiling machine 100 is just opened, coolant circulating system is just transported in air-conditioning
Turn, there are no enough colds or heat for heat exchanger 2 to exchange heat.The air for flowing through heat exchanger 2 at this time is unable to get heat exchange, into
Almost without the temperature difference between air temperature and leaving air temp.So need first to wait for the booting of ceiling machine 100 and operate the second preset time,
Just start to control incoming air area control piece 7 according to the temperature difference.Optionally, the second preset time is less than or equal to 5 minutes.
In above-described embodiment, the first preset area is less than or equal to the 1/2 of the maximum incoming air area of the second air inlet 102, into
Optionally, the first preset area is the 1/3 of the maximum incoming air area of the second air inlet 102 to one step.In this way when the temperature difference is larger, control
The less intake of the second air inlet 102 is made, cold and hot combined amount is reduced, is conducive to quickly exchange heat when the temperature difference is larger in this way.
In the above-described embodiments, the second preset area is the 80%-100% of the maximum incoming air area of the second air inlet 102.
In this way when the temperature difference is smaller, the larger intake of the second air inlet 102 of control increases cold and hot combined amount, is conducive in this way in temperature
The smaller guarantee outlet air of difference is soft.
In the above-described embodiments, incoming air area control piece 7 closes the second air inlet 102, and dehumidification device 9 is inoperative always.
When the second air inlet 102 of opening of incoming air area control piece 7, the switch for controlling dehumidification device 9 is just needed.Wherein, whenever air intake surface
Product control piece 7 opens the second air inlet 102, needs to meet setting condition, dehumidification device 9 just operates.
For example, in the above-described embodiments, when incoming air area control piece 7 controls the second air inlet 102 with the first preset area
When air inlet, the operating dehumidifying of dehumidification device 9；It is entered the wind with the second preset area when incoming air area control piece 7 controls the second air inlet 102
When, dehumidification device 9 shuts down.
For example, in the above-described embodiments, in the first setting time after the second air inlet 102 starts air inlet, dehumidifying dress
Set 9 operatings dehumidifying；Later, dehumidification device 9 does not rerun dehumidifying.In some embodiments, as shown in Figure 1, ceiling machine 100 also wraps
It includes：Humidity Detection part 90 is relatively wet when the air that Humidity Detection part 90 is used to detect the second air inlet 102 of inflow does not dehumidify
Degree, dehumidification device 9 are electrically connected with Humidity Detection part 90, to control the operation of dehumidification device 9 according to Humidity Detection value.
It is understood that when the air humidity for entering the second air inlet 102 is larger, it is easy to be formed in ceiling machine 100
Condensed water influences device operation, needs timely hydrofuge.And when air humidity is smaller, the probability for forming condensed water becomes smaller.Using
Humidity Detection part 90 controls the operation of dehumidification device 9, is conducive to the energy consumption for saving ceiling machine 100.
In embodiments of the present invention, the position of Humidity Detection part 90 is very flexible, and Humidity Detection part 90 can be located at first
