Description

Air conditioner.

The present invention relates to an apparatus of air conditioning with an indoor module provided within a local that is about air conditioning, with a first heat exchanger heat, as well as an external module functionally linked with the inner module by means of connecting ducts such as electrical cables, a conduit of refrigerating agent or the like, and which is planned outside the enclosure that is to be heated, in The outside atmosphere The outer module has a blower with blades to generate a stream of directed air over a second heat exchanger, and a bottom provided below the blower to collect the condensation water that may drip, in which is provided a drain hole through which you can drain the condensation water that has been accumulated.

An air apparatus is known from EP 1660517 conditioning according to this species. The air apparatus conditioning carries an internal module located inside a enclosure that is about air conditioning as well as an outdoor module provided in the outside atmosphere. In the outer module is provided a condenser that cools with condensation water with in order to increase performance. Condensation water that dripping from the condenser is collected in an accumulator container, which it can be emptied through a drain hole that can close.

The object of the present invention is in provide an air conditioner that works well reliable regardless of the weather conditions of the outside atmosphere

The objective of the present invention is solved by means of an air conditioner that presents the characteristics of claim 1. According to the part characterizing claim 1, has been formed in a bottom of an outer module located in the outer atmosphere an element of separation that subdivides the fund into two sections of the fund. A first section of the bottom leads the condensation water to drain into a drain hole in the outer module. The element of separation prevents the accumulation of condensation water in the second section of the bottom, under the blades of the blower. The second section of the bottom located under the blades of the blower it is therefore inaccessible to the condensation water that is accumulates in the first tranche of the fund. This avoids the danger that in the case of outside temperatures correspondingly low, ice may form below the blower blades. This prevents contact between blower blades and ice formed in the bottom, which would negatively influence the operation of the air apparatus conditioned.

According to an embodiment example advantageously, the separator element is formed as a partition separator, which separates the first section of the bottom of the second section From the bottom. This way you can safely prevent water from condensation that is falling accumulates under the blades of the blower

According to another embodiment, the element separator can be formed by an elevation that protrudes from the First section of the fund. An upper face of the elevation forms the second section of the bottom, under the blades of the blower.

It is advantageous that the second tranche of the fund also be in communication with the drain hole. This way the condensation water that eventually drips onto the second section of the bottom can be evacuated through the hole of sewer system.

The gravity drain of the condensation water of the first or second tranche of the fund can be improved, giving to the bottom sections an inclination, in particular of 2 °, towards the drain hole.

Since, according to the invention, no ice forms under the blades of the blower, can be reduced notably the construction height of the blower in the module Exterior. The outer contour line of the blower blades It can approach up to 2 or 3 mm above the bottom. In this way, the outdoor module can be built compact and sparse height.

It is especially advantageous if the device air conditioning object of the invention can work not only as an ambient cooling device but also in regime of ambient heating. In cooling regime of ambient, the second heat exchanger provided in the module Outside acts as a condenser. In this case, the hole of External module drain is closed by an element of closing. Condensation water is conducted from the indoor module to the external module through a connection duct. In the module outside the condensation water is distributed over the second heat exchanger in order to increase its performance of condensation The dripping condensation water is collected in the background. Due to the low construction height of the blower, the condensation water collected at the bottom is collected by the blades of the blower and thrown back on the second heat exchanger. On the other hand, under heating ambient, the second heat exchanger of the outdoor module It acts as an evaporator in which water condenses. In this If the drain hole of the outdoor module is open. From this way the condensation water can drip from the second heat exchanger on the first section of the bottom, and evacuate through the drain hole. This avoids the  risk of icing in the outdoor module, which Presents when outside temperatures are low.

Two examples of embodiment of the invention, using the attached figures. These can be seen:

Fig. 5 a view corresponding to Figure 4, according to the second embodiment.

In Figure 1 it is represented, according to the first embodiment, an air conditioner with an internal module 3 and an external module 9. The internal module 3 of the air conditioner is located inside the enclosure that is about air conditioning 1. The outdoor module 9 is provided in the outdoor atmosphere 11. The two modules 3 and 9 are linked together by means of a conduit mallet 7. The mallet of pipes 7 passes for example through an open window up to the outer module 9. In this case the outer module 9 it can be placed on an exterior wall in the area of the window. In conduit deck 7 they are assembled for example electrical wires, a conduit of refrigerating agent or the condensation water line 8 which is represented in the Figure 2. The inner module has a first known form heat exchanger 5, and the outer module 9 a second heat exchanger 17. The second heat exchanger 17 It is represented in detail in Figure 2. It follows that the second heat exchanger 17 is U-shaped. Among the two arms of the U-shaped exchanger 17 is located a blower 13 with blades 15. Blower 13 is mounted on a clamp 18. A lower end of clamp 18 is placed in the bottom 19. An upper end of the fastener 18 is mounted on the outer module housing, which is not represented. The heat exchanger 17 seats with a shaped front end of U on the bottom 19 of the outer module 9. As is shown in Figure 4, the bottom 19 is inclined at an angle to in the direction of a drain channel 31. The drain channel 31 is in communication with the outside atmosphere 11 through a drain hole 32. In Figures 2 to 4 there is an element of closure 33 that keeps drain hole 32 closed. Figure 2 further deduces that bottom 19 is formed a partition wall 29. The partition wall 29 subdivides the bottom 19 in a first section of fund 23 and in a second section of fund 25. The second tranche of fund 25 is limited according to the Figure 2, on the one hand by the separating wall 29 as well as by the drain channel 31. From Figure 4 it follows that the line of outer contour 27 of the blades of the blower 15 approaches the second section of bottom 25 to a small distance (a) from approximately 3 mm.

The following describes the operation in cooling system of the air apparatus environment conditioning 1: Under ambient cooling, the second heat exchanger 17 in the outdoor module 9 works as condenser The first heat exchanger 5 in the module interior 5 acts as an evaporator, in which the water condenses of condensation of the ambient air. The condensation water is accumulates in the indoor module 3. By means of a pump, which is not represented, the condensation water is conducted to the module outside 9 through the condensate line 8 which is represented in Figure 2. Condensate line 8 flows in the outer module 9 in the area above the blades of the blower 15. Therefore, under refrigeration ambient, the condensation water drips on the blades of the blower 15, which throws it towards the heat exchanger 17 U-shaped. In this way the condensation water will mainly distributes the heat exchanger 17. In this way the condensation efficiency of the second heat exchanger 17. Operating the air apparatus air conditioning cooling system, the drain hole 32 is further closed by means of the close 33. Therefore, dripping water accumulates in the bottom 19. For that reason, the level of condensation water accumulated in fund 19 may rise while operating ambient cooling When the water level approaches the outer contour line 27 of the blades of blower 15, the blades of blower 15 collect the water accumulated in bottom 19 and the they launch again against the heat exchanger 17. So so much, the condensation water that drips from the water line of condensation 17 is collected, on the one hand, directly by the  blades of blower 15 and distributed over exchanger 17. By On the other hand, the blades of blower 15 can also collect water directly from bottom 19 and distribute it on the exchanger of heat 17.

Operating the air conditioner in ambient heating regime, the first exchanger of heat 5 of the indoor module 3 works as a condenser for heating the enclosure 1. The second exchanger 17 of the module exterior 9 acts as an evaporator. In this case, the water of the outside atmosphere condenses on the second heat exchanger heat 17. In the second heat exchanger 17 the water from condensation drips in the direction of the arrow to the second leg from bottom 23. The second section of bottom 23 conducts water from accumulated condensation 21 to the drain channel 31. In the ambient heating, this channel is not closed by the closing element 33. Therefore condensation water 21 flows through the drain channel 31 outside the outer module 9.

Due to the separation wall 29, the first bottom section 25 located under the blades of blower 15 It is inaccessible to the water that drains in the second section of the fund 23. In this way there is no risk that when the air conditioner run on heating from the environment, the condensation water 21 dripping from the exchanger 17 reaches the first section of the bottom 25. Therefore, in the case of outside temperatures below the point of freezing can not form ice in the first section of the bottom 25. This advantageously prevents ice from entering contact with the outer edges of the blades of the blower 15. That contact would negatively influence the operation of the blower 13.

The second embodiment of the invention is shown in Figure 5. In contrast to the first embodiment, the two sections of the bottom 23, 25 are not subdivided by the separation wall 29. Rather, an elevation 30 of the first section of the bottom 23 protrudes. An upper face of the elevation 30 forms the second bottom section 25. The second section of bottom 25 on elevation 30 is therefore inaccessible to the condensation water 21 that drains into the first section of the
background 23.
