The present embodiment provides an air conditioner that performs a cooling and heating cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The cooling and heating cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and cools or heats an indoor space.
The compressor compresses refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.
The expansion valve expands the high-temperature and high-pressure liquid-phase refrigerant condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigerating effect by heat exchange with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner can adjust the temperature of the indoor space throughout the cycle.
The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor, an outdoor heat exchanger, and an outdoor fan, the indoor unit of the air conditioner includes a portion of an indoor heat exchanger and an indoor fan, and a throttling device (e.g., a capillary tube or an electronic expansion valve) may be provided in the indoor unit or the outdoor unit.
The indoor heat exchanger and the outdoor heat exchanger serve as a condenser or an evaporator. The air conditioner performs a heating mode when the indoor heat exchanger serves as a condenser, and performs a cooling mode when the indoor heat exchanger serves as an evaporator.
The indoor heat exchanger and the outdoor heat exchanger are switched to be used as a condenser or an evaporator, a four-way valve is generally adopted, and specific reference is made to the arrangement of a conventional air conditioner, which is not described herein again.
The refrigeration working principle of the air conditioner is as follows: the compressor works to enable the interior of the indoor heat exchanger (in the indoor unit, the evaporator at the moment) to be in an ultralow pressure state, liquid refrigerant in the indoor heat exchanger is rapidly evaporated to absorb heat, air blown out by the indoor fan is cooled by the coil pipe of the indoor heat exchanger to become cold air which is blown into a room, the evaporated and vaporized refrigerant is compressed by the compressor, is condensed into liquid in a high-pressure environment in the outdoor heat exchanger (in the outdoor unit, the condenser at the moment) to release heat, and the heat is dissipated into the atmosphere through the outdoor fan, so that the refrigeration effect is achieved by circulation.
The heating working principle of the air conditioner is as follows: the gaseous refrigerant is pressurized by the compressor to become high-temperature and high-pressure gas, and the high-temperature and high-pressure gas enters the indoor heat exchanger (the condenser at the moment), is condensed, liquefied and released heat to become liquid, and simultaneously heats indoor air, so that the aim of increasing the indoor temperature is fulfilled. The liquid refrigerant is decompressed by the throttling device, enters the outdoor heat exchanger (an evaporator at the moment), is evaporated, gasified and absorbs heat to form gas, absorbs the heat of outdoor air (the outdoor air becomes cooler) to form gaseous refrigerant, and enters the compressor again to start the next cycle.
Referring to fig. 1, according to some embodiments of the present application, an indoor unit of an air conditioner for connecting an outdoor unit of the air conditioner includes:
the air conditioner comprises a shell 1, wherein an air inlet 11 and an air outlet 12 are arranged on the shell 1, an air supply channel 13 is arranged in the shell 1, and the air supply channel 13 is positioned between the air inlet 11 and the air outlet 12;
the indoor heat exchanger 2, the indoor heat exchanger 2 is set up in the air supply channel 13;
the fan 3 is arranged in the shell 1, and the fan 3 is used for driving air introduced from the air inlet 11 to be conveyed through the air supply channel 13 and output from the air outlet 12;
a mounting part 4, wherein the mounting part 4 is provided with a mounting opening 41 and at least one ventilation opening 42;
the mounting member 4 is disposed in the air supply passage 13, the mounting member 4 divides the air supply passage 13 into an air inlet section 101 and an air outlet section 102, and the indoor heat exchanger 2 is disposed in the mounting port 41.
Specifically, in the actual use process, after the fan 3 is powered on, the indoor air enters the air supply channel 13 through the air inlet 11, and the air flow is conveyed to the mounting component 4.
After the airflow flows to the mounting part 4, part of the airflow passes through the indoor heat exchanger 2 and exchanges heat with the refrigerant flowing in the indoor heat exchanger 2, so that the air passing through the indoor heat exchanger 2 is cooled or heated, and the heat exchanged air enters the air outlet section 102.
Since the mounting member 4 is provided with the ventilation opening 42 to directly communicate the air inlet section 101 and the air outlet section 102, the remaining air flow directly enters the air outlet section 102 from the ventilation opening 42.
In this way, the air flow generated after the fan 3 is started does not need to exchange heat with the indoor heat exchanger 2 completely, and more importantly, the air flow output from the ventilation opening 42 can effectively increase the whole air output of the air conditioner indoor unit. Therefore, indoor air can flow circularly and fully, and the indoor heat is uniformly distributed.
Through set up the installation component in the air supply passageway at the shell, the installation component is used for fixing the installation of indoor heat exchanger in the air supply passageway on the one hand, form the vent on the other hand installation component, the vent is located one side of indoor heat exchanger, and then when fan drive air current flows in the air supply passageway, partial air current carries out the heat exchange with indoor heat exchanger and continues to flow to the air outlet direction, and remaining air current then directly crosses indoor heat exchanger through the vent and continues to flow to the air outlet direction, thus, in order to guarantee the normal heat transfer of indoor heat exchanger, guarantee that the whole air output of indoor set of air conditioner satisfies the abundant circulating flow's of indoor air requirement, so that indoor temperature distributes evenly, improve the air output of indoor set of air conditioner, in order to improve user experience nature.
In some embodiments of the present application, the air output from the vent 42 is mixed with the air heat-exchanged via the indoor heat exchanger 2 in the outlet section 102.
Specifically, for the air flow sent by the air supply channel 13, part of the air flow exchanges heat with the indoor heat exchanger 2, and the rest of the air flow does not exchange heat with the indoor heat exchanger 2. After the air current after heat exchange and the remaining air current enter the air outlet section 102 of the air supply channel 13, the two air currents are mixed in the air outlet section 102, so that the mixed air current is output from the air outlet 12, the air current can be softer, the condition that the user is uncomfortable due to the fact that the air current output from the direct blowing air outlet 12 is reduced, and the use experience of the user is better improved.
The specific structural form of the fan 3 can be selected according to the type and characteristics of the indoor unit of the air conditioner.
In an embodiment of the present application, the fan 3 is a centrifugal fan.
Specifically, under the condition that fan 3 adopts centrifugal fan, then can be according to the corresponding configuration of length size of indoor heat exchanger 2 and have a plurality of centrifugal fan, and then satisfy the requirement of air supply.
In another embodiment of the present application, the fan 3 is a crossflow fan.
Specifically, when the cross-flow fan is adopted as the fan 3, the cross-flow fan extends along the length direction of the indoor heat exchanger 2, so that the air flow output by the fan 3 is uniformly distributed, and the uniformity of the air flow distribution is improved.
The installation position of the fan 3 includes at least the following two modes, which will be described below with reference to the drawings.
As shown in fig. 1, the fan 3 is located in the air intake section 101.
Specifically, the fan 3 is installed inside the housing 1 and located in the air intake section 101, and after the fan 3 is started, air is blown toward the installation part 4. Wherein, the air flow blown by the fan 3 is directed towards the indoor heat exchanger 2 and the ventilation opening 42 to ensure smooth flow of the air flow.
Preferably, the outlet of the fan 3 outputs an air flow toward the indoor heat exchanger 2.
Specifically, the air outlet direction of the fan 3 faces the indoor heat exchanger 2 to ensure that sufficient air flow exchanges heat with the indoor heat exchanger 2, and further ensure the heat exchange efficiency.
As shown in fig. 2, the fan 3 is located in the air outlet section 102.
Specifically, the fan 3 is located in the air outlet section 102 so that the mounting component 4 is located on the air inlet side of the fan 3, and after the fan 3 is started, negative pressure is formed on the air inlet side of the fan 3, so that the outside air enters the air supply channel 13.
Wherein, in order to ensure that the indoor heat exchanger 2 can fully exchange heat, the inlet of the fan 3 can be arranged close to the indoor heat exchanger 2, so as to ensure that the indoor heat exchanger 2 can obtain enough air flow to perform sufficient heat exchange.
In some embodiments of the present application, the mounting member 4 is of a plate-like structure and is arranged obliquely in the air blowing passage 13.
Specifically, the mounting member 4 is used to mount the indoor heat exchanger 2, and also needs to satisfy the requirement of ventilation, and for this purpose, the mounting member 4 is installed in the air supply passage 13 in an inclined manner.
Thus, the whole area of the installation part 4 can be effectively increased, the installation requirement of the indoor heat exchanger 2 with larger heat exchange area can be further met, the ventilation opening 42 can be simultaneously increased, and the requirement of increasing the whole air supply quantity of the indoor unit can be finally met.
In another embodiment, the indoor heat exchanger 2 is also disposed in an inclined manner, that is, the indoor heat exchanger 2 is also disposed in the air supply passage 13 in an inclined manner.
Specifically, the indoor heat exchanger 2 is obliquely arranged in the air supply passage 13, so that the heat exchange area of the indoor heat exchanger 2 is increased in a smaller volume.
In other embodiments, an openable and closable damper (not shown) is provided in the vent 42.
Specifically, in the using process of the user, when the user needs to perform forced cooling or heating, the air flow needs to be reduced and is not directly output through the indoor heat exchanger 2, and for this reason, the opening and closing degree of the ventilation opening 42 can be controlled through the air door, so that the flow of the heat exchange air flow is adjusted.
Among them, as for the vent 42, it is possible to provide a plurality of vents 42 as needed. For example: ventilation openings 42 may be provided at upper and lower portions of the indoor heat exchanger 2, respectively.
Specifically, the plurality of ventilation openings 42 can increase the overall air output of the indoor unit of the air conditioner, and the ventilation openings 42 are respectively arranged above and below the indoor heat exchanger 2, so that corresponding air flow control and adjustment can be performed during cooling and heating.
In the cooling mode, the air heat-exchanged by the indoor heat exchanger 2 is formed into cold air having a large specific gravity, and in order to increase the air blowing distance, the vent 42 above the indoor heat exchanger 2 may be closed by a damper and the vent 42 below the indoor heat exchanger 2 may be opened. In this way, the air output from the ventilation opening 42 is located below the cold air after heat exchange in the indoor heat exchanger 2, and the room temperature air is used to extend the air supply distance of the cold air, thereby improving the uniformity of the indoor temperature distribution.
In the heating mode, the air heat-exchanged by the indoor heat exchanger 2 forms hot air, and the specific gravity of the hot air is light. Similarly, in order to increase the air supply distance, the vent 42 below the indoor heat exchanger 2 may be closed by a damper, and the vent 42 above the indoor heat exchanger 2 may be opened. In this way, the hot air after heat exchange in the indoor heat exchanger 2 is located below the air output from the ventilation opening 42, and the room temperature air is used to push down the hot air to extend the air supply distance, thereby improving the indoor temperature distribution uniformity.
In some embodiments of the present application, the ventilation opening 42 is a strip-shaped hole extending in the length direction or the width direction of the indoor heat exchanger 2.
Specifically, the ventilation opening 42 is designed to be of a strip-shaped structure, so that the air outlet area can be effectively increased, and the integral air outlet quantity of the indoor unit of the air conditioner can be increased.
The foregoing is directed to preferred embodiments of the present invention, other and further embodiments of the utility model may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow. However, any simple modification, equivalent change and modification of the above embodiments according to the technical essence of the present invention are within the protection scope of the technical solution of the present invention.
