Description

  The present invention relates to an air conditioner that self-treats drain water.

An air conditioner installed in a place where it is difficult to secure a drainage route, such as the upper part of the elevator car's outside, the condenser that dissipates the heat of the compressed refrigerant, and the surroundings by evaporating the liquefied refrigerant An evaporator for cooling the water, a water tray provided below the evaporator and the condenser, and drain water sent from the water tray provided above the condenser and dripping the drain water onto the top surface of the condenser And a drain water dripping device.
In addition, a water-absorbing ventilation member made of thick cloth-like water-absorbing plastic is substantially the same size as the condenser, and the lower edge is located at the upper part of the water basin, provides a predetermined space, faces the leeward side, and protrudes from the condenser It is held by a holding frame. Moreover, the evaporating dish of the drain water dripping device is extended to the upper part of the water absorption ventilation member, and a plurality of drain water dripping holes are provided at the upper position of the water absorption ventilation member. In addition, a drain transpiration filter is interposed between the transpiration dish and the condenser in order to spread the drain water dripped from the drain water drips hole of the transpiration dish of the drain water dripping device uniformly over the entire surface of the condenser.

Since the condenser is heated to approximately 50 to 60 ° C. by the high-temperature refrigerant, the drain water evaporates by the heat, evaporates into the atmosphere by the wind power of the blower, and is discharged from the ventilation port by an exhaust fan or the like. The drain water remaining without transpiration is led to the water tray and the transpiration operation is repeated.
Moreover, a part of drain water is dripped from the drain water dripping hole part provided so that it may be located in the windward side of a water absorption ventilation member, and dripping focusing on the surface of the wind absorption side of a water absorption ventilation member. In this way, the drain water adhering to the water-absorbing ventilation member is evaporated by the warm air from the blower heated by the condenser (see, for example, Patent Document 1).

JP-A-8-303813 (FIG. 14)

  However, since the drain transpiration filter is pressed against the upper surface of the condenser with only the transpiration dish, there is a partial gap between the upper surface of the condenser and the drain transpiration filter when replacing the drain transpiration filter during maintenance work. However, there is a problem that the drainage water does not fall uniformly into the condenser, the transpiration efficiency is lowered, and the air conditioner cannot be fully operated in a season when the amount of the drain water is large.

  An object of the present invention is to provide an air conditioner in which a drain transpiration filter is arranged without a gap from the upper surface of a condenser and has a large self-treatment capacity of drain water.

  An air conditioner according to the present invention is an air conditioner in which drain water generated in an evaporator and stored in a water tray is sent to a evaporating dish located above the condenser by a drain pump, dripped and evaporated to self-process, The drain transpiration filter that covers the upper surface of the condenser, the water-absorbing ventilation member that faces the side surface of the condenser, and the lower surface of the transpiration dish, and uniformly presses the drain transpiration filter against the upper surface of the condenser and And a comb-shaped spacer that positions the drain transpiration filter so as to contact the water-absorbing ventilation member.

  The effect of the air conditioner according to the present invention is that when the water-absorbing ventilation member is in wide contact with the drain transpiration filter, the drain water penetrating the drain transpiration filter penetrates more into the water-absorption ventilation member and increases the transpiration amount of the drain water. it can.

FIG. 1 is a schematic view of a portion related to self-treatment of drain water of an air conditioner according to the present invention.
The air conditioner 1 according to the present invention is installed in a place where it is difficult to discharge the drain water generated by an evaporator of a refrigeration cycle (not shown) to the outside and to process it, for example, in a building. It is installed at the top of the elevator car outside.
The air conditioner 1 includes a compressor (not shown) that compresses the refrigerant gas, a condenser 2 that radiates and liquefies the compressed refrigerant gas, and an evaporator (not shown) that evaporates the liquefied refrigerant. Has a connected refrigeration cycle.

As shown in FIG. 1, a water basin 5 is disposed below the condenser 2 and the evaporator. A drain pump 10 for sending drain water to the upper side of the condenser 2 and a water level meter 11 for detecting the water level of the drain water for controlling the start / stop of the drain pump 10 are arranged at the corners of the water reservoir 5. .
In addition, a drain water dropping device 13 that once receives drain water sent from the drain pump 10 and drops it from above the condenser 2 is provided above the condenser 2. The drain pump 10 and the drain water dripping device 13 are communicated with each other through a drain hose 14. A drain transpiration filter 15 that contacts the upper surface of the condenser 2 and spreads drain water over the entire upper surface of the condenser 2 is disposed above the condenser 2.

The drain water dripping device 13 is in contact with the evaporating dish 16 for distributing the drain water sent via the drain hose 14 over the entire upper surface of the condenser 2, and the lower surface of the evaporating dish 16. A comb-shaped spacer 17 that uniformly presses the drain transpiration filter 15 covering the entire surface against the upper surface of the condenser 2 is formed.
As shown in FIG. 2, the evaporating dish 16 is provided with a drain water dripping hole portion 21 for dripping drain water, and the drain water sent from the drain hose 14 passes through the drain water dripping hole portion 21 to be a drain transpiration filter. Drip on 15. The evaporating dish 16 is provided with an upper positioning member 22 for positioning the upper portion of the water-absorbing ventilation member.
As shown in FIG. 3, the comb-shaped spacer 17 has a large number of comb teeth 17a.

The air conditioner 1 further includes a water-absorbing ventilation member 18 made of thick cloth-like water-absorbing plastic having substantially the same dimensions as the condenser 2 on the leeward side of the condenser 2. The water-absorbing ventilation member 18 is positioned by inserting a lower portion into a lower positioning member 23 fixed to the water storage tray 5 with a lower edge in contact with the bottom of the water storage tray 5 and an upper edge in contact with the drain transpiration filter 15. ing. Further, the upper positioning member 22 extending downward from the bottom surface of the evaporating dish 16 is positioned by inserting the upper portion thereof.
Since the drain transpiration filter is pressed by the comb spacer 17 from above 15, the upper edge of the water-absorbing ventilation member 18 is in contact with the side surface of the drain transpiration filter 15 over the entire surface.
In addition, the air blower 7 raises the wind so that the air flows from the condenser 2 to the water absorption ventilation member 18.

Next, a state until drain water is generated and evaporated is described.
In the evaporator, the surroundings are cooled by evaporating the liquefied refrigerant. As the surroundings cool, water molecules contained in the surrounding air condense into water droplets and flow down as drain water. This drain water is received by the water reservoir 5 and is sent by the drain pump 10 to the evaporating dish 16 disposed above the condenser 2. And it is dripped on the drain transpiration filter 15 through the drain water dripping hole 21 from the transpiration dish 16. One of the drain water dropped onto the drain transpiration filter 15 penetrates to the upper surface of the condenser 2, and is evaporated on the surface of the condenser 2. On the other hand, it penetrates to the water-absorbing ventilation member 18 and is evaporated in the water-absorbing ventilation member 18.
In addition, since the drain water is directly sucked into the water-absorbing / ventilating member 18 by the capillary phenomenon, the drain water is also evaporated in the water-absorbing / venting member 18. In this way, the lower edge of the water-absorbing ventilation member 18 is in contact with the bottom of the water basin 5 and is directly sucked from the water basin 5 due to capillary action. Can be transpired.

  Thus, if the water absorption ventilation member 18 contacts the drain transpiration filter 15 widely, the drain water which permeate | transmits the drain transpiration filter 15 will osmose | permeate a lot in the water absorption ventilation member 18, and the transpiration | evaporation amount of drain water can be increased. On the other hand, when the comb-shaped spacer 17 is not provided, there is a gap between the drain transpiration filter 15 and the water absorption ventilation member 18, and the drain water does not smoothly penetrate from the drain transpiration filter 15 into the water absorption ventilation member 18. There is a possibility that the air conditioner 1 may be temporarily stopped at a time when the amount of transpiration is reduced and the amount of drain water generated is large.

  Moreover, since the water absorption ventilation member 18 contacts the side surface of the condenser 2 by positioning the water absorption ventilation member 18 with the lower positioning member 23 and the upper positioning member 22, heat is transferred from the condenser 2 to the water absorption ventilation member 18. As a result, the temperature of the water-absorbing / venting member 18 is greatly increased, the transpiration rate of the drain water penetrating the water-absorbing / venting member 18 is increased, and the transpiration amount of the drain water is increased. On the other hand, if the water-absorbing ventilation member 18 is disposed away from the condenser 2, the heat conduction from the condenser 2 to the water-absorbing ventilation member 18 becomes extremely small, and the temperature rise of the water-absorbing ventilation member 18 is small. The transpiration rate of drain water that permeates the water becomes slow, and the transpiration amount of drain water is small.

It is the schematic of the part in connection with the self-treatment of the drain water of the air conditioner concerning this invention. It is a top view of the evaporating dish concerning this invention. It is a top view of a comb-shaped spacer concerning this invention.
