Detailed Description
A specific embodiment of the air conditioning unit according to the present embodiment will be described in detail below with reference to fig. 1 to 8. In the following description, when the side of the air conditioning unit, which is close to the wall, is rear, the side opposite to the wall is front, the side contacting the ground is lower, and the side opposite to the ground is upper, the user faces the front panel of the air conditioning unit, and the left and right sides of the air conditioning unit are the left and right sides of the air conditioning unit.
As shown in fig. 1 to 4, the air conditioning unit of the present embodiment mainly includes a condensing unit 100 and an evaporating unit 200 that are disposed in a split manner, and both of the units are rectangular parallelepiped, and in an assembled state, the two units are combined together from top to bottom in a vertical direction, and the two units are disposed in alignment in a front-rear direction and a left-right direction, respectively. The specific structure of the foregoing two units is described in detail below.
Condensing unit 100
As shown in fig. 1 to 8, the condensing unit 100 is formed in a rectangular parallelepiped shape, and has a condensing unit housing 110 formed in a rectangular parallelepiped shape, a water receiving tray 111 is installed in the condensing unit housing 110 and is arranged approximately centrally in the up-down direction, the periphery of the water receiving tray 111 is hermetically connected to the inner wall surface of the condensing unit housing 110, and a water outlet of the water receiving tray 111 is communicated with a water drainage system of an air conditioning unit through a water pipe. The inner space of the condensing unit housing 110 is substantially divided into an upper condensing unit first chamber 120 and a lower condensing unit second chamber 130 by the water tray 111, and the first chamber of the present invention is constituted by the condensing unit first chamber 120. Because the inner space of the condensing unit 100 is directly divided by the water pan 111, the additional addition of the partition plate in the condensing unit 100 to form the two chambers can be avoided, the inner structure of the air conditioning unit can be simplified, the number of required parts is reduced, and the installation process of the air conditioning unit is simplified. In addition, since the water pan 111 is generally pressed by a plate, that is, the water pan 111 is an integral component rather than being formed by splicing a plurality of plates, the air tightness of the separation between the first chamber 120 of the condensing unit (for outdoor air and/or indoor air to circulate) and the second chamber 130 of the condensing unit (for outdoor air to circulate) can be improved, so that the cooling capacity loss of the air conditioning unit when the air conditioning unit operates in the natural cooling mode or the mixed mode is avoided. In addition, in rainy and snowy days or when the condenser 140 is cleaned, water can be timely discharged to the outside of the unit through the water discharge outlet of the water receiving tray 111, so that the unit is prevented from being broken down or the water is prevented from being blown into the room due to the water entering the indoor air circulation side.
A condenser 140 is installed in the first chamber 120 of the condensing unit, and the condenser 140 is formed of two fin type heat exchangers symmetrically arranged and arranged in a V shape as viewed from the side of the air conditioning unit, and the top of the V-shaped structure is generally in sealing connection with the inner wall surfaces of the front and rear sides of the first chamber 120 of the condensing unit. A pair of baffles for sealing the V-shaped opening are generally symmetrically disposed at both left and right sides of the condenser 140, and the interior space of the condensing unit first chamber 120 is partitioned into a condenser air-intake side chamber and a condenser air-outlet side chamber below the condenser 140 by the condenser 140 and the pair of baffles.

The condensing fan 150 is installed on the top plate 117 of the condensing unit 100, in this embodiment, the condensing fan 150 is an axial flow fan, and is installed on the top plate 117 in such a way that its axial direction is perpendicular to the top plate 117, so that an air inlet of the condensing fan 150 is opposite to a V-shaped opening of the condenser 140, and an air outlet thereof is upward, thereby realizing top air exhaust of the air conditioning unit. The condensing fan 150 discharges hot air upwards from the top, so that poor condensation caused by large difference of air inlet quantity of two condensers due to different wind directions in windy weather can be avoided. In addition, the top exhaust also avoids the interference of strong wind to the condensing fan 150, and also avoids the mutual interference among the groups when a plurality of units are operated simultaneously.
In particular, the top plate 117 is integrally formed with a slope portion 117a, and the slope portion 117a is inclined downward from the rear to the front when seen from the side of the air conditioning unit, and by using the slope portion 117a, rainwater at the top of the air conditioning unit can be rapidly drained away, so that the damage to the unit caused by water accumulated at the top of the unit or the infiltration into the air inlet along a gap between the unit and the wall body can be avoided.
An outdoor air inlet 118 for allowing outdoor air to enter the second chamber 130 of the condensing unit is formed in the lower part of the front panel 112 of the condensing unit 100, and a detachable air inlet grille or filter screen is also generally installed at the outdoor air inlet 118; a first filter 131 is installed on the outdoor air inlet 118 in the second chamber 130 of the condensing unit, and in this embodiment, the first filter 131 is a nylon mesh filter; an indoor return air inlet 119 for allowing indoor air to enter the second chamber 130 of the condensing unit is formed in the lower part of the rear panel 115 of the condensing unit 100, and an indoor return air valve 132 is installed at the indoor return air inlet 119; a condensing unit opening is formed at the bottom of the condensing unit 100, and a medium-efficiency filter 133 is installed on the condensing unit opening in the condensing unit second chamber 130; an outdoor air intake valve 134 for controlling the volume of the outdoor air introduced thereinto is also installed in the condensing unit second chamber 130.
As shown in fig. 4 and 6 to 8, a rain cover 160 may be further installed on the front side of the condensing unit 100 at the outdoor air intake 118, and the rain cover 160 is typically formed by pressing a steel plate or by injection molding a plastic, and in this embodiment, the rain cover 160 includes a rain cover main body, and rain cover side plates located on both sides of the rain cover main body, and the rain cover main body includes a horizontal portion 161, an inclined portion 162 and a vertical portion 163 (see fig. 4) which are connected in this order, as seen from the side of the air conditioning unit. The outdoor air inlet enters the air conditioning unit from the lower opening of the rain cover 160, and the rain cover 160 can prevent the rainwater from entering the unit when the outdoor air enters the unit.

As shown in fig. 7, under the suction of the evaporation fan 241, the outdoor air enters the unit through the outdoor air inlet 118, flows through the first filter 131, the outdoor air inlet valve 134, the intermediate filter 133, the evaporator 231, and the evaporation fan 241 in this order, and finally enters the room through the indoor air outlet 213.
Under the positive pressure of the indoor air, the indoor hot air enters the first chamber 120 of the condensing unit through the residual pressure exhaust outlet 116, most of the hot air is exhausted to the outside from the outdoor air inlet 118, and a small part of the hot air flows through the condenser 140 and is exhausted to the outside from the top of the condensing unit 100.
In addition, when the outdoor temperature is low, the supply air temperature can be adjusted by opening the indoor return air valve 132. The opening ratio of the outdoor air inlet valve 134 and the indoor air return valve 132 can be specifically adjusted to adjust the ratio of indoor air return to outdoor air inlet, so as to ensure that the air supply temperature is within a reasonable range.
3. Partial natural cooling mode
When the outdoor temperature is in a proper range, the unit operates in a partial natural cooling mode. The residual pressure exhaust valve 121, the outdoor air intake valve 134 and the indoor return air valve 132 are opened, and the condensing fan 150, the evaporating fan 241 and the compressor 222 are operated.
As shown in fig. 8, under the suction of the evaporating fan 241, outdoor air enters the unit through the outdoor air inlet 118 and the outdoor air inlet valve 134, indoor return air enters the air conditioning unit through the indoor air return port 119 and the indoor air return valve 132, and after the two gases are mixed, the two gases sequentially flow through the intermediate-efficiency filter 133, the evaporator 231 and the evaporating fan 241, and finally enter the room through the indoor air supply port 213;
under the suction of the condensing fan 150, the outdoor air enters the air conditioning unit through the condensing air inlets 114 positioned at the front and both sides, flows through the condenser 140 and absorbs the heat emitted by the condenser, and is discharged to the outside from the top;
under the positive pressure of the indoor air, the indoor hot air enters the first chamber 120 of the condensing unit through the residual pressure exhaust port 116, flows through the condenser 140 under the suction of the condensing fan 150, and finally is exhausted to the outside from the top of the condensing unit 100.
As can be seen from the above, after the outdoor air enters the air conditioning unit, the outdoor air enters the room through the outdoor air inlet 118, the outdoor air inlet valve 134, the intermediate filter 133, the evaporator 231 and the evaporating fan 241 in sequence, and finally enters the room through the indoor air outlet 213, so that even if the outdoor air brings a small amount of water drops into the air conditioning unit, the outdoor air can intercept and filter the small amount of water drops for many times through the components when flowing through the components, and the air finally entering the room is ensured to be clean and dry.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
