First, as shown in FIGS. 1 and 2, the integrated air conditioner 100 for a heavy equipment cabin according to the present invention is disposed on the outer side of the cabin 10 for the heavy equipment, more specifically, on the rear side, and is described below. The front side discharge port 134 of the base 130 is configured to discharge cold air into the cabin 10 as it passes through the rear wall of the cabin 10 and communicates with the room.

2 and 4, the integrated air conditioner 100 for a heavy-duty cabin according to the present invention is an outdoor unit and an indoor unit in which the outdoor unit 120 and the indoor unit 130 are built in the main body casing 110. It is composed. Here, the outdoor unit 120 is a long-axis outdoor unit formed in a horizontal direction in the left and right and includes a compressor and a condenser 122, and the indoor unit 130 is an evaporator 132 arranged side by side on one side of the outdoor unit 120. ). 4 is a view of the inside of the integrated air conditioner 100 for a heavy-duty cabin according to the present invention as viewed from the rear side, as shown, the first outdoor partition 120 and the indoor base 130 are spaced apart from each other at regular intervals It is configured to be disposed separately by 115 and the second partition (116). And, the front of the body casing 110 between the first partition 115 and the second partition 116, the cabin 10 so that the internal air (hereinafter referred to as 'bet') of the cabin 10 flows into the indoor base 130 ( 10) A bet inlet 114 communicating with the interior is formed.

The main body casing 110 is a housing for accommodating components such as a condenser 122, an expansion valve 139, and an evaporator 132 therein, and is formed vertically elongated in a horizontal direction on the rear upper side of the cabin 10 It is preferably configured to reduce the space occupied in the direction, it is fixedly installed by a separate fastener (not shown) on the rear upper side of the cabin 10.

The outdoor unit 120 includes a condenser 122 that is formed to be long in the horizontal direction on one side of the body casing 110 as shown. The condenser 122 receives the refrigerant gas compressed at high temperature and high pressure from the compressor and converts it into a liquid at high temperature and high pressure. Here, although the compressor is not shown, it may be disposed inside the main body casing 110, or may be separately configured outside the main body casing 110 and connected to the condenser 122 and the refrigerant pipe. The condenser 122 is provided with refrigerant pipes 122a and 122b serving as headers on both sides of the left and right sides, a plurality of refrigerant pipes (not shown) are connected between the pipes, and heat sinks are provided on the outside, thereby providing high temperature and high pressure. When the refrigerant gas passes, heat is discharged to the outside to change the refrigerant from a gas state to a liquid phase.

More specifically, as shown in FIG. 3, a plurality of intake grills 111 are formed in the main body casing 110 of the outdoor unit 120 in which the condenser 122 is disposed, and external air (hereinafter referred to as 'outside air'). ) To be introduced, a heat dissipation fan 124 is provided on the rear side of the condenser 122, and an exhaust grill 112 is formed on the rear and bottom surfaces of the body casing 110 of the outdoor unit 120 to form a condenser 122 ) It is configured to discharge heat dissipated from the heat sink on the surface to the outside. At this time, since the refrigerant gas passing through the inside of the condenser 122 is deprived of heat by relatively low outside air, it is condensed and changed into a liquid phase.

The high-temperature, high-pressure liquid refrigerant converted into a liquid from the condenser 122 is transferred to the indoor unit 130 through a pipe (not shown). An expansion valve 139 and an evaporator 132 are disposed in the indoor unit 130. The expansion valve 139 expands the liquid refrigerant of high temperature and high pressure formed in the condenser 122 to change it to low temperature and low pressure. Then, the low-temperature, low-pressure liquid refrigerant that has passed through the expansion valve 139 is changed to a low-temperature, low-pressure gas state in the evaporator 132 disposed on one side of the condenser 122.

More specifically, the evaporator 132 evaporates a low-temperature low-pressure liquid refrigerant to a low-temperature low-pressure gas by introducing a relatively high temperature inside air and exchanging heat with the refrigerant. 4 and 5, such a bet is introduced through a bet inlet 114 formed between the first partition 115 and the second partition 116 of the body casing 110. Here, the first partition wall 115 is a wall adjacent to the outdoor unit 120 side to block the incoming air from entering the outdoor unit 120, and the second partition wall 116 is the indoor unit 130 An opening formed in the center as a wall adjacent to the side is configured to allow the inside air introduced through the inside air inlet 114 to flow into the indoor base 130. At this time, the opening of the second partition wall 116 is provided with a purification filter 118 to perform an air cleaning function by filtering contaminants of the bet flowing into the indoor unit 130. The purification filter 118 is configured to slide in and out along the filter guide rail 119 formed on the second partition wall 116 to allow cleaning after separation.

On the other hand, a pipe passage through a refrigerant pipe (not shown) for transferring refrigerant between the outdoor unit 120 and the indoor unit 130 passes through the corners of the first partition 115 and the second partition 116 ( 115a, 116a) are formed. The gap between the piping through holes 115a and 116a and the refrigerant piping is sealed with silicone or the like to prevent air or air from leaking.

The inside air introduced into the indoor unit 130 is cooled by heat exchange with the evaporator 132 and then discharged back into the cabin 10 through the discharge port 134. 6 is an external perspective view (a) and a partial exploded view (b) of the indoor base 130. As illustrated, the evaporator 132 of the indoor unit 130 is built in the evaporator casing 133, and a fan 136 is provided on the rear side of the evaporator casing 133. The fan 136 is provided with a total of two, one on each of the left and right sides, a fan motor 137 for rotating the fan 136 on both sides is disposed in the center. The fan motor 137 is provided with rotating shafts on both left and right sides so that both fans 136 can be simultaneously rotated. The fan 136 is sucked through the openings of the air inlet 114 and the second bulkhead 116, and the air flowing into the indoor unit 130 is sucked and blown, and then discharged through the evaporator 132 to the discharge port 134. As possible. The inside air is lowered by heat exchange with the evaporator 132 to be changed into cold air, and discharged into the cabin 10 through a plurality of outlets 134 provided on the rear side of the evaporator casing 133 to cool the air.

Meanwhile, the condensate generated inside the evaporator casing 133 by heat exchange in the indoor unit may be discharged to the outside through the condensate discharge pipe 138 shown in FIG. 6 (a).

The refrigerant that has been exchanged with the inner air in the evaporator 132 and changed to a low-temperature and low-pressure gas is recovered back to the compressor through a refrigerant gas recovery pipe (not shown), and the cooling cycle is terminated once and continuous cooling is performed by repeating the cooling cycle. do.

As described above, inside the main body casing 110 of the integrated air conditioner 100 for a heavy-duty cabin according to the present invention, the outdoor unit 120 and the indoor unit 130 are integrally built, so that the indoor unit and the outdoor unit are separately equipped with conventional cooling. Compared to the device, the occupied space can be reduced, and in particular, the indoor unit does not protrude into the cabin 10, so it has an advantage of securing a wide indoor space.
