The heat pipe in the embodiment can be arranged in an air conditioner with an outdoor fan, and can also be used in an air conditioner without the outdoor fan.

Through the mode, the size of the shell of the unit is reduced while the unit is convenient to install and maintain.

The design and a specific operation of the air conditioner will be described below with reference to other relevant components of the air conditioner.

As shown in fig. 1, the integrated air conditioner without a fan at the outer side in this embodiment has an overall structure including a compressor, an outdoor heat exchanger 7 (condenser), a throttle mechanism, an indoor fan 9, an indoor heat exchanger 8 (evaporator), a water pan 13, a water pipe 6, a heat pipe 14, an electromagnetic water valve 11, a level gauge, a metal plate and a pipe. The part arranged in the outdoor space of the air conditioner mainly comprises a compressor, a condenser, a throttling mechanism, an evaporation part (serving as the evaporation side part of a heat pipe), a part of water conveying pipeline 6 (extending out of a water drain port of a water receiving disc and being arranged at the outdoor side), a part of matched sheet metal and pipeline parts; the part of the indoor space of the air conditioner mainly comprises an evaporator, an indoor fan 9, a water receiving disc 13, an electromagnetic water valve 11, a liquid level meter, a condensation part (serving as a condensation side part of a heat pipe), a part of water conveying pipeline 6 (extending out of a water outlet of the water receiving disc and being positioned at the indoor side) and an electric cabinet.

The metal plates are arranged in the middle of the indoor side and the outdoor side for sealing and separating, so that the cold quantity and the air flow on the indoor side and the outdoor side are not influenced. And a few pipe penetrating holes are formed in the middle of the metal plate and are used for connecting a refrigerant flow path between the evaporator and the condenser, a heat pipe evaporation side flow path and a condensation side flow path, and a water conveying pipeline 6 communicated with the water receiving disc 13. Considering that the pipe penetrating hole needs to have good sealing performance, the machine needs to be strictly glued.

The indoor evaporator 8 is arranged at the middle height, and the centrifugal fan at the evaporation side is arranged on the upper side, so that the whole wind direction of the indoor side is from bottom to top. Because the evaporator needs to vertically intake air to achieve higher heat exchange efficiency and the air intake mode of the centrifugal fan. Therefore, the air conditioner is integrally provided with the air inlet at the upper front side and the air outlet at the lower front side. The lower part of the indoor side evaporator is provided with a water pan 13, and the condensation side of the heat pipe is arranged at the bottom of the water pan 13, so that the cold energy of the condensed water can be used for precooling the air input by the outdoor side air inlet 3 at the first time. Because the water pan 13 cannot always receive the condensed water, when the condensed water reaches a certain height (upper level gauge) in the water pan 13, the electromagnetic water valve on the water conveying pipeline 6 communicated with the water pan 13 is opened, and the condensed water is directly communicated to the top of the condenser of the air conditioner for water spraying. Under the condition, the heat transfer of the condensation side is changed into a heat dissipation form similar to spraying of water on the heat exchanger, and the heat exchange efficiency is greatly improved. In order to avoid affecting the continuous cooling effect of the heat pipe on the precooling of the condenser, the height of a lower limit liquid level meter of the water receiving tray 13 needs to be set, namely the height of the condensed water of the water receiving tray 13 just smeared on the condensation side of the heat pipe is generally determined according to the pipe diameter of the heat pipe and is generally about 10 mm. And (4) draining water by the water receiving disc 13 until the liquid level meter at the lower side, closing the electromagnetic water valve 11 and stopping the drainage process. And the water receiving disc 13 continues to collect the condensed water until the condensed water reaches the upper side liquid level meter again, the electromagnetic water valve 11 is opened, the drainage process is started, and the like.

It should be noted that: the reason why the above-mentioned condensed water is not directly sprayed on the condenser of the air conditioner is as follows. The condensed water of the air conditioner has a collecting process, and is directly sprayed to the air conditioner to be little when the air conditioner is just started, so that the effect of heat exchange on the condensation side is poor. More importantly, the water sprayed on the condenser quickly evaporates after meeting the surface of the condenser at about 60 ℃ to generate phase change heat absorption. And the water vapor can quickly rise after evaporation and flows to the air outlet at the top of the outer side along with the chimney effect to be discharged. This results in a low utilization efficiency of the cold energy of the low-temperature condensed water, and a large amount of water falls out of the outdoor air inlet 3 (including the first air inlet and the second air inlet) as soon as possible after spraying. Therefore, in the embodiment, the heat pipe mode is adopted to fully utilize the temperature difference heat, and then the condensed water with slightly high temperature and slightly poor quality is sprayed, so as to achieve the purpose of fully utilizing the cold energy of the condensed water. Meanwhile, after condensed water is discharged through the condenser, the structure shows that the condensed water is directly adjacent to the two air inlets on the outdoor side, so that the drainage is smooth; meanwhile, if part of water drops are attached to the two air inlets, the water drops can be further evaporated after being subjected to heat transfer by the temperature difference of the outdoor environment, and the water drops float up through the condenser, so that the heat exchange effect of the condenser is enhanced again.

The outdoor condenser is arranged at a downward position, and the evaporation side of the heat pipe is arranged obliquely below the condenser. The outdoor air inlet 3 is arranged at the lower position of the outdoor part of the air conditioner shell, and the final air inlet direction is ensured to be vertical to the surface of the condenser through sheet metal flow guide. In this embodiment, two air inlets are preferably provided on the outdoor side. One air inlet is arranged at the bottom of the shell and used for sucking normal outdoor air by utilizing a chimney effect, one air inlet (a second air inlet) is arranged at the lower position of the outdoor side panel 10 of the shell, and the air inlet is an air suction opening at the outdoor side when the air exhaust function is started at the indoor side. First, the second air inlet of the outdoor side panel 10 is directly perpendicular to the air inlet of the condenser, and the second air inlet is provided with an air valve 18 structure, because the air enters the outdoor part of the air conditioner when the indoor side has air exhaust. When the indoor exhaust fan is started, the air valve 18 is opened, and the outdoor side air intake is mainly indoor side air exhaust. When the indoor side fan 9 is closed, the air valve 18 is closed, and at the moment, the air valve 18 is in a sealing structure. Air entering from the bottom of the outdoor side passes through the cavity and is blocked by the top metal plate and the air valve 18, and all air is precooled by the evaporation side of the heat pipe and then enters the condenser for heat exchange. Because the condenser has a temperature of about 60 ℃, and the temperature difference can reach 30-40 ℃ due to the fact that the air is pre-cooled through the heat pipe in addition to the inlet air. The air intake is heated by the condenser and then rises to generate driving force, and the air conditioner is provided with the air inducing cover 19 to improve the height difference of the air entering and leaving the outdoor side of the air conditioner, so that the driving force of a chimney effect can be easily generated, and the natural convection is changed into the forced convection with certain driving force. But consider that the vertical position of the evaporator must be higher than the vertical position of the condenser for this layout. Because of the gravity heat pipe principle, the evaporation side of the gravity heat pipe is only arranged below, and the gravity heat pipe can float to the condensation side of the heat pipe (exchanges heat with the condensed water of the water receiving tray) after absorbing heat to release heat and then condense and flow downwards to complete a whole set of circulation. The outdoor air outlet 4 is arranged at the top of the air conditioner, and is used together with the optional air draft cover 19 to increase the height difference of the outdoor air inlet and outlet.

The air inducing cover 19 at the outdoor side is connected with the outer part of the air conditioner in a buckling or sliding way, the cross section size of the first end of an air inducing channel formed by the air inducing cover 19 is equivalent to the size of the air outlet 4 at the outer side of the air conditioner, and the second end of the air inducing channel formed by the air inducing cover is used as an air outlet. The draft cover 19 is arranged in a stretchable and contractible structural layout, sufficiently considering whether there is enough space in an environment where the air conditioner is actually installed. Meanwhile, when the space is enough, the telescopic induced draft cover 19 is stretched to the longest, so that the chimney effect can be greatly improved. The heat exchange efficiency of the outdoor side is greatly improved under the condition of practical installation feasibility. Meanwhile, the outdoor fan is not installed in the air conditioner, so that the power actually consumed by the air conditioner can be reduced, and the operation energy consumption is further reduced.

When the indoor side independent fresh air system of the air conditioner works, in order to keep the pressure balance of the indoor side, a corresponding exhaust fan 16 can lead away a part of air. The indoor side exhaust pipe can be led to the bottom of the outdoor side of the air conditioner, and the cold energy of indoor side exhaust is fully utilized. Meanwhile, the exhaust fan 16 can just provide the condition of forced convection heat exchange for the outside of the air conditioner, namely, under the condition that the fan is not arranged on the outside of the air conditioner, the driving force of the exhaust fan 16 is fully utilized, so that the outdoor heat exchanger 7 is in the state of forced convection heat exchange, and the running energy consumption of the air conditioner is improved. The condensate from the refrigeration system is still being collected and this condensate still needs to be drained. Considering that the air conditioner has very little precooling of the evaporation part of the heat pipe under the condition that the exhaust fan 16 leads the indoor airflow to forcibly exchange heat with the outdoor fan. Therefore, the electromagnetic water valve 11 on the water conveying pipeline 6 is normally opened, the generated condensate water is directly communicated to the upper part of the condenser of the air conditioner, and heat exchange of the condensing side of the air conditioner is enhanced.

In the present embodiment, a description is also given of a control logic between some components of the air conditioner.

1) When the exhaust fan 16 is started, the outdoor side air inlet valve 18 is opened, and at this time, outdoor side air inlet is mainly provided by indoor side exhaust, that is, mainly air inlet from the air inlet 2, and at this time, the electromagnetic water valve 11 is kept in a normally open state.

2) When the exhaust fan 16 is closed, the outdoor side intake air valve 18 is closed, and at this time, the outdoor side intake air can only enter from the air inlet 1.

The on-off condition of the electromagnetic water valve is controlled as follows according to the water quantity height of the water receiving tray 13:

1) when the water level of the water receiving tray 13 rises to the height of the upper liquid level meter, the electromagnetic water valve is opened;

2) when the water level of the water receiving tray 13 is lowered to the height of the lower volume liquid level meter, the electromagnetic water valve is closed.

Wherein, based on the above control logic, the water level in the water receiving tray 13 can be controlled between the height of the upper level meter and the height of the lower level meter. Therefore, the condensed water is ensured not to overflow the water receiving disc 13, and not to be completely discharged to cause the heat exchange of the heat pipe to be influenced.

Exemplary embodiments of the present disclosure are specifically illustrated and described above. It is to be understood that the present disclosure is not limited to the precise arrangements, instrumentalities, or instrumentalities described herein; on the contrary, the disclosure is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
