Therefore, the auxiliary heater needs to heat the cold air and blow the cold air into the room as hot air. The heating process of the constant temperature and humidity unit can cause serious energy waste and is not beneficial to indoor temperature control.

With the improvement of the energy-saving requirement of the air conditioner, the energy consumption of the constant temperature and humidity unit during operation becomes the most power-consuming air conditioner product in the air conditioner products, the power of the constant temperature and humidity unit is nearly doubled compared with that of the air conditioner unit under the same cooling capacity, and the space for reducing the energy consumption of the constant temperature and humidity unit is still large. The constant temperature and humidity machine is used as a special air conditioner, when the air conditioner is used, the air flow organization meeting the use place can normally circulate, the constant temperature and humidity machine can always run, the inner fan always runs when heating and defrosting, the running of the inner fan can not provide heat for the use place but provide cold for the use place, and after defrosting is finished, heat is supplemented to the use place through a system and electric heating, and the defrosting treatment mode causes serious waste of energy. In order to solve the above problems, the present application provides an air conditioner, which has the following specific structure:
as shown in fig. 1, an air conditioner of the present application includes a case 10, a heat exchanger 20, and a heating device. An air duct 11 is formed in the housing 10, and the housing 10 is provided with a first air inlet 12, a second air inlet 13 and an air outlet 14 which are communicated with the air duct 11. The heat exchanger 20 and the heating device 30 are disposed in the casing 10 and located in the air duct 11, wherein the air conditioner has a first air outlet mode and a second air outlet mode, when the air conditioner is in the first air outlet mode, an air flow entering from the first air inlet 12 passes through the heat exchanger 20 and the heating device 30 and then blows out from the air outlet 14, and when the air conditioner is in the second air outlet mode, an air flow entering from the second air inlet 13 passes through the heating device 30 and then blows out from the air outlet 14.
By applying the technical scheme of the embodiment, when the air conditioner is in the ordinary refrigeration and heating mode, the air conditioner is in the first air outlet mode. When the air conditioner is in the defrosting mode and the air conditioner is in the heating mode, the air conditioner is in the second air outlet mode, and at the moment, the air flow is blown out from the air outlet 14 after passing through the heating device 30, so that the condition that the air flow is heated by the heating device 30 after being cooled by the heat exchanger 20 and needs a large amount of energy is prevented. Therefore, the technical scheme of the embodiment solves the problem that more energy is wasted when the air conditioner in the prior art heats.
In this example, the airflow may be guided in various ways, such as arranging the heat exchanger 20, the heating device 30, the first air inlet 12 and the second air inlet 13 in the housing 10, or providing an air guiding structure in the housing 10, so that when the airflow enters from the first air inlet, the airflow can pass through the heat exchanger 20 and the heating device 30, and when the airflow enters from the second air inlet, the airflow only passes through the heating device 30. The specific guiding manner for the airflow can be determined according to actual working requirements.
As shown in fig. 1, in the solution of the present embodiment, the first air inlet 12 and the second air inlet 13 are both disposed on a side wall of the housing 10. The first air inlet 12 and the second air inlet 13 are arranged oppositely, and the heat exchanger 20 and the heating device 30 are arranged between the first air inlet 12 and the second air inlet 13, wherein the first air inlet 12 is arranged on one side of the heat exchanger 20 far away from the heating device 30, and the second air inlet 13 is arranged on one side of the heating device 30 far away from the heat exchanger 20.
As shown in fig. 1, in the solution of the present embodiment, the heat exchanger 20 and the heating device 30 are stacked. The heat exchanger 20 and the heating device 30 are disposed obliquely in the housing 10. The distance between the upper end of the heat exchanger 20 and the side wall where the first air inlet 12 is located is smaller than the distance between the lower end of the heat exchanger 20 and the side wall where the first air inlet 12 is located. Specifically, the first air intake vent 12 and the second air intake vent 13 are disposed on both sides in the thickness direction of the heat exchanger 20. I.e., the heat exchange surface of the heat exchanger 20 faces the first air inlet and the second air inlet. The heat exchanger 20 and the heating device 30 are stacked, and the heating device 30 is located above the heat exchanger 20. The heating device 30 is disposed opposite to the second air inlet 13, and the heat exchanger 20 is disposed opposite to the first air inlet 12. The above structure forms the following structure: as can be seen from fig. 1, the second air intake 13, the heating device 30, the heat exchanger 20 and the first air intake 12 are arranged in sequence in the left-to-right direction. Meanwhile, the upper portions of the heating device 30 and the heat exchanger 20 are both inclined toward the first air inlet 12. With the above structure, how the air conditioner of the present embodiment performs the function of "when the air flow enters from the first air inlet, the air flow can pass through the heat exchanger 20 and the heating device 30, and when the air flow enters from the second air inlet, the air flow only passes through the heating device 30" will be described below:
as shown in fig. 2, the airflow flow in fig. 2 shows the airflow direction when the air conditioner is in the first wind outlet mode. Specifically, the first intake vent 12 is in an open state, and the second intake vent 13 is in a closed state. When the air conditioner is operated, the fan generates negative pressure, and air flow enters from the first air inlet 12, passes through the heat exchanger 20 and then passes through the heating device 30. When the air conditioner is cooling, the heat exchanger 20 is an evaporator, and the heating device 30 does not operate. When the air conditioner heats, the heat exchanger is a condenser, and the heating device 30 selectively performs auxiliary heating according to the working condition.
As shown in fig. 3, the airflow flow in fig. 3 shows the airflow direction when the air conditioner is in the second outlet mode. Specifically, the first air inlet 12 is in a closed state, the second air inlet 13 is in an open state, when the air conditioner is operated, the fan generates negative pressure, air flows through the second air inlet 13, the air flow firstly passes through the heating device 30, and then the air flow directly flows to the air outlet 14 under the action of the negative pressure of the fan. It should be noted that in this example, a small portion of the airflow entering from the second air inlet passes through the heat exchanger 20, but under the driving of the negative pressure of the fan 50, most of the airflow does not pass through the heat exchanger 20 and directly flows to the air outlet 14.
Of course, the air conditioner may have other air outlet modes, for example, in an embodiment not shown, the first air inlet 12 and the second air inlet 13 may be opened simultaneously when the air conditioner is operated, so as to realize the opposite air inlet of the air conditioner.
As shown in fig. 1, in the solution of the present embodiment, a water pan 40 is disposed at the bottom of the heat exchanger 20 and the heating device 30. The water pan is used for collecting condensed water generated on the heat exchanger 20.
As shown in fig. 1, in the solution of the present embodiment, the air outlet 14 is disposed at the top of the housing 10. A fan 50 is arranged between the air outlet 14 and the heat exchanger 20. The first air inlet 12 and the second air inlet 13 are both located below the fan 50, and the first air inlet 12 and the second air inlet 13 are located at two sides of the fan 50 respectively.
Preferably, the heating device 30 is an electric heater.
Preferably, a first baffle is disposed at the first air inlet 12, and the first baffle can open or close the first air inlet 12. A second baffle is arranged at the second air inlet 13, and the second baffle can open or close the second air inlet 13. The first baffle and the second baffle can control the opening or closing of the first air inlet 12 and the second air inlet 13, so as to realize a first air outlet mode and a second air outlet mode.
In the present application, besides the above-mentioned structure, the first air outlet mode and the second air outlet mode can be realized, and other arrangements of the heat exchanger 20, the heating device 30, the first air inlet 12 and the second air inlet 13 can be selected. For example, in an embodiment not shown, the heat exchanger 20 and the heating device 30 are disposed between the first air intake 12 and the second air intake 13, wherein the first air intake 12 and the second air intake 13 are disposed on a side wall of the housing 10 corresponding to a vertical side of the heat exchanger 20 and the heating device 30, the first air intake 12 is located at a lower side of the heating device 30, and the second air intake 13 is located at an upper side of the heat exchanger 20.
Specifically, referring to fig. 1, the specific arrangement positions of the first intake vents 12 and the second intake vents 13 described above are a position on the inner side of the paper and a position on the outer side of the paper. The first air inlet 12 is disposed below the heating device 30. When the airflow passes through the first air inlet 12, the airflow passes through the heat exchanger 20 and the heating device 30 from bottom to top. The second intake vent 13 is disposed above the heat exchanger 20, and there is an overlapping portion between the second intake vent 13 and the heating device 30. When the air flow enters from the second air inlet 13, the air flow firstly passes through the heating device 30 and then is discharged out of the air outlet 14 upwards.
