Detailed description of the invention
Fig. 1 is the structural block diagram according to a kind of unit of the utility model embodiment.
Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments, it should be understood that this place
The specific embodiment of description is only used to explain the utility model, is not used to limit the utility model.
In subsequent description, it is only using the suffix for indicating such as " module ", " component " or " unit " of element
The explanation for being conducive to the utility model, itself does not have a specific meaning.Therefore, " module ", " component " or " unit " can be with
Mixedly use.
In order to solve air conditioner in the related technology, in dehumidifying, room temperature is reduced, and influences the feelings of the usage experience of user
Condition.The utility model embodiment provides a kind of unit, as shown in Figure 1, the unit includes: the first valve 6, the second valve 4, dehumidifying
Reheating heat exchanger 1,
First valve 6 is arranged on the connecting line between the compressor 5 of unit and the condenser 8 of unit, in machine
It is closed when group operation dehumidification mode；
Second valve 4 is arranged on the connecting line between compressor 5 and the reheating heat exchanger 1 that dehumidifies, in unit fortune
It is opened when row dehumidification mode, so that the refrigerant that compressor 5 is discharged flow to dehumidifying reheating heat exchanger 1；
Dehumidify reheating heat exchanger 1, and the air outlet side of the evaporator 2 of unit is arranged in, for refrigerant to be precooled,
To save the heat of refrigerant, and heated using air of the heat to air outlet side.
As a result, when unit is in dehumidification mode, after high temperature and high pressure gas is precooled via dehumidifying reheating heat exchanger, then into
Enter condenser, so that heat exchanger can be added using the cold wind that the heat saved when precooling blows out evaporator again for dehumidifying
Heat avoids room temperature from reducing, to improve the usage experience of user.
In one possible implementation, unit can be air conditioner, and the first valve 6, the second valve 4 can be two
Port valve, dehumidifying reheating heat exchanger 1 and the evaporator 10 of unit be oppositely arranged, dehumidifying reheating heat exchanger 1 both ends respectively with compression
Machine 5 and condenser 8 connect.It will be appreciated that the first valve 6 is closed when unit runs dehumidification mode, then compressor 5 is discharged
High-temperature high-pressure refrigerant will not flow to condenser 8 and cooled down.And second valve 4 open, then the high temperature that compressor 5 is discharged is high
Compression refrigerant can flow directly into dehumidifying reheating heat exchanger 1 through the second valve 4 and be precooled, and dehumidifying reheating heat exchanger 1 is being pre-chilled
But during, it can be reserved for the heat of refrigerant.After refrigerant is precooled via dehumidifying reheating heat exchanger 1, followed by cold
After condenser 8, throttling set 9, evaporator 10, it is back to compressor 5.And refrigerant is when being evaporated in the vaporizer 10, blowout
Cold wind can be heated via the dehumidifying reheating heat exchanger 1 being oppositely arranged with evaporator 10, then can avoid room temperature reduce,
To improve the comfort and usage experience of user.
Wherein, 10 it is shown the cold wind direction that evaporator is blown out, 11 show the final air-out direction of unit.And condenser
8 sides are provided with outer blower 7, and 10 side of evaporator is provided with inner blower 3.
And when environment temperature is lower, unit provided by the embodiment of the utility model, which can avoid temperature in dehumidification process, to be reduced
To minimum temperature threshold compressor emergency shutdown is protected, to guarantee that stablizing for unit is dehumidified, improves the adaptability of unit.
In one possible implementation, the first valve 6 is also used to the unlatching when unit runs refrigeration mode, so that
Refrigerant flows through condenser 8 and is cooled down, the second valve 4 is also used to the closing when unit runs refrigeration mode, to avoid system
Cryogen flows into dehumidifying reheating heat exchanger 1.When air-conditioning is normally carried out refrigerating operaton, the high-temperature high-pressure refrigerant of the discharge of compressor 5
Enter the cooling of condenser 8 after being directly over the first valve 6, condensed liquid refrigerant enters throttling set 9, finally flows into and steams
Hair device 10 is evaporated.Since refrigerant is not by dehumidifying reheating heat exchanger 1, the cold wind of evaporator blowout is by dehumidifying reheating
It will not be heated when heat exchanger 1, room temperature lowering can be sent to protect the cold wind of evaporator blowout, realize the purpose normally freezed.
