Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an individual air conditioner used for adjusting a working environment, particularly in an office.

<Conventional technology> Air conditioning management is one of the ways to improve the working environment in the workplace.

This air conditioning is generally performed by arranging an air duct from a central heating system or the like in each required air-conditioned room or installing a heat exchange terminal device such as a fan coil unit. ing.

However, if the room is relatively large and the sunshine changes depending on the time of day, it may be difficult to comfortably air-condition the entire room as described above.

In addition, since there is individual difference in comfort with respect to the air-conditioning temperature, the above-mentioned overall collective air-conditioning is not always the optimum method.

Therefore, in recent years, as so-called individual air conditioning, an idea has been presented in which an air conditioner unit is arranged on an individual's work desk, for example, so that air conditioning can be performed according to each person's preference.

<Problems to be Solved by the Invention> One of the problems in performing air conditioning is treatment of drain water such as dehumidifying water generated by an air conditioner unit as a terminal device.

As the drain water treatment method in the case of the individual air conditioning described above,
For example, drain water discharge pipes of a plurality of air conditioner units may be installed outdoors with water gradients, or they may be concentrated in the middle and drained to the outside with the main pipe, or even pumped up. A method of mechanically draining water is considered.

However, in the drainage system as described above, since the discharge pipe is routed inside the room, if there is a possibility of a leak due to an unexpected situation, copying equipment, computer equipment, etc. installed in the room There is a risk that equipment and machinery will be adversely affected such as breakdown. In addition, there is a concern that mechanical drainage such as a pump will cause a malfunction.

The present invention was made in order to solve the problems of the individual air conditioning system as described above, and its purpose is to:
It is an object of the present invention to provide a drain water treatment device for an individual air conditioning device, which is capable of individually treating the drain water generated by the individual air conditioning system with a simple configuration.

<Means for Solving the Problems> In order to achieve the above object, the present invention provides an individual air conditioner configured to blow out conditioned air from an air conditioner unit to an indoor air-conditioned space, and a drain pan of the air conditioner unit. Connect one end side of the hollow tube to and open the other end to the outside,
A part of the high temperature side refrigerant pipe of the air conditioner unit is inserted into the hollow pipe and a capillary substance is attached to the high temperature side refrigerant pipe of this insertion part, and drain water generated in the air conditioner unit is converted into the capillary substance. It is configured so that it is permeated by a capillary action and is vaporized by heat of a refrigerant to be discharged.

<Operation> The drain water generated by the operation of the air conditioner unit accumulates in the drain pan and flows out into the hollow pipe from the connection portion of the hollow pipe. Since the high temperature side refrigerant pipe of the air conditioner unit is inserted with the capillary substance in the hollow pipe, the drain water permeates the capillary substance and proceeds in the hollow pipe. Then, in the course of this progress, the drain water is heated by the heat of the refrigerant and rises in temperature, so that it is sequentially vaporized and vaporized, and discharged from the outlet side of the hollow tube to the outside of the room.

As described above, the drain water of the air conditioner unit is quickly evaporated and discharged to the outside of the room each time it is generated, so that there is no problem of causing a water leakage accident on the way unlike the drainage of piping. In addition, since power equipment such as a pump is not used for drain water discharge, reliability and economic efficiency are improved.

<Embodiment> A preferred embodiment of the present invention will be described below with reference to the drawings when it is applied to a floor-standing type individual air conditioner.

FIG. 1 is a side view illustrating a configuration of a drain water treatment device of an individual air conditioner according to the present invention, and FIG. 2 is an enlarged explanatory view of a main part of the drain water treatment device.

In the figure, reference numeral 1 is a work desk body, and the operator is positioned with the left side of the figure as the front side of the desk body 1.

Reference numeral 2 denotes an air conditioner unit, which is a refrigeration cycle unit as a terminal unit in which a specific configuration is omitted, for example, an indoor heat exchanger, a fan, etc. are integrated in a casing.
Therefore, in the air conditioner unit 2, a suction port (not shown) for taking in nearby air and a conditioned air duct for blowing out conditioned air whose temperature and the like are adjusted by heat exchange to the air-conditioned space around the worker (see FIG. (Not shown). Reference numeral 3 is a refrigerant pipe connected to one of the indoor heat exchanger of the air conditioner unit 2 and an outdoor heat exchanger (not shown) for forming a refrigerant circulation circuit, that is, a high temperature refrigerant in the case of cooling operation. Is used as the high temperature side refrigerant pipe.

Reference numeral 4 denotes a drain pan, which is arranged near the bottom of the air conditioner unit 2 so as to receive drain water such as dehumidifying water generated during cooling. Reference numeral 4a denotes a dust removing filter provided at the drain water discharge port of the drain pan 4.

Reference numeral 5 is an elongated hollow tube, one end side 5a of which is connected and opened to the drain water discharge port of the drain pan 4, and the other end side 5b thereof penetrates the chamber partition wall W and is opened to the outside of the room.

Further, in the present invention, a part of the high temperature side refrigerant pipe 3 is inserted into the hollow pipe 5, and the refrigerant pipe 3 at the insertion portion penetrates water such as cloth or sponge. It is attached by winding or adhering a capillary material with good properties.

With such a configuration, the drain water D generated by the operation of the air conditioner unit 2 is drained from the drain pan 4 to the hollow pipe 5.
Spills in. Then, in the hollow tube 5, it penetrates into the capillary substance 6 and proceeds, but in the process, the temperature is raised by the high temperature side refrigerant tube 3. The refrigerant flowing in the high temperature side refrigerant pipe 3 is 50
Since the drain water D is at a relatively high temperature of about 0 ° C., it is in a so-called heated state. Then, in the process of permeating the capillary substance 6, the drain water D gradually starts to evaporate, that is, vaporizes. Then, the vaporized steam drain water Da flows out of the room from the other end side 5b of the hollow tube 5.

In addition, the outflow of the steam drain water Da, that is, the discharge, is practical even if the pipe diameter of the hollow pipe 5 is relatively large, especially on the other end side 5b, and if it is arranged as an upslope, the pressure rise due to the temperature may increase. However, if the connection opening of the one end side 5a of the hollow pipe 5 to the drain pan 4 receives the fan blowing pressure of the air conditioner unit 2, the steam drain water Da can be discharged more efficiently. Can be done.

<Effect of Device> As described above, according to the present invention, the drain water from the air conditioner unit is quickly vaporized without being passed through the indoor pipe, so that it is possible to prevent the water from leaking in the middle of the pipe. There is no problem that causes an unexpected accident to equipment.

In addition, since it is not necessary to use a power device such as a pump for discharging drain water, maintenance can be omitted, reliability can be increased, and economic efficiency can be improved.
