Description

SLEEVE ASSEMBLY BURIED UNDER VERANDA FOR CARRYING AIR CONDITIONER PIPES}

The present invention relates to a structure for embedding a sleeve connecting body for embedding air conditioner piping, for example, on the veranda floor of an apartment or a town house. In particular, the indoor unit is located in the living room and the outdoor unit is a refrigerant circulation pipe of a separate air conditioner placed outside the building. In connection with the problem of exposing to the outside across a veranda, the present invention relates to a sleeve connector embedding structure for embedding an air conditioning pipe so that the air conditioning pipe can be embedded in the floor of the veranda.

In general, a separate type air conditioner using a phase change circulation cycle of a refrigerant includes an indoor unit 6 placed in an interior including an evaporator 2 and a blowing fan 4 and a compressor (as shown in FIG. 1). 8), an outdoor unit 16 placed outdoors including the condenser 10 heat radiating fan 12 and an expansion valve 14 and a refrigerant passage pipe 18 for circulating and connecting the indoor unit 6 and the outdoor unit 16 to each other. 20) is provided. The gaseous refrigerant evaporated from the evaporator 2 is compressed to a gaseous state of high temperature and high pressure by the compressor 8 in the outdoor unit 16, and then heat-exchanged by the action of the heat radiating fan 12 and the condenser 10. The liquefied refrigerant is passed through the expansion valve (14) and the pressure is reduced, the first valve 22 on the pipe 18 (ie, liquid pipe) side, the second on the pipe 18 and the pipe 18 side. The valve 24 flows into the evaporator 2 of the indoor unit and evaporates to absorb surrounding heat. The cold air formed at this time is discharged into the room by the blower fan 4 located adjacent to the evaporator 2. The refrigerant evaporated in the evaporator 2 is the first valve on the side of the pipe 20 (ie, the gas pipe). (26), the pipe 20 and the pipe 20 are supplied to the compressor 8 of the outdoor unit again through the second valve 28 and circulated.

When installing an air conditioner in which the outdoor unit 16 and the indoor unit 6 are separated, the pipes 18 and 20 through which the refrigerant flows are generally liquid pipe insulation 32 around each pipe, as shown in FIG. 2. And gas pipe insulation 32 is installed, and the PVC tape 36 is wound around them and installed integrally. The refrigerant pipes 18 and 20 connect the outdoor unit 16 and the indoor unit 6 so that the outdoor unit and the indoor unit are separated and placed on the veranda floor of the apartment or the townhouse or along the veranda ceiling. It can only be exposed to the outside. The external exposure of the pipes 18 and 20 not only harms the interior aesthetics, but it also catches the foot during the passage of the porch or is hit by the object when it is transported, resulting in the leakage of high-pressure refrigerant to the outside and when cleaning the porch. Uncomfortable. In FIG. 2, reference numeral 30 is a pipe for discharging condensation condensate generated during heat exchange of the evaporator 2, and reference numeral 31 is an electric wire for driving the compressor 10 of the outdoor unit, which is not shown in FIG. 1.

On the other hand, in each room and living room of an apartment or townhouse, hot water pipes for heating are installed, and cement mortar is finished thereon, so that the floor is raised by a predetermined thickness, for example, about 100-110 mm above the reference slab layer, but the front or rear side of the house is increased. The floor height of the veranda is about 90-100mm lower than the floor height of the living room because the floor of the veranda, which is divided into the floor, is generally not covered by heating pipes and is finished by attaching tiles directly on the surface of the slab. However, the recent tendency of finishing the floor height of the living room side of apartments or townhouses to be almost the same as the height of the living room floor is because, firstly, considering the frequent entry and exit between the living room and the balcony during living, In order to reduce the inconvenience of entering and exiting by reducing the step of the veranda floor as much as possible, and to improve the ease of expansion when the second living room is to be extended to the veranda. However, since there is usually no door and only a predetermined height of window between the room and the veranda, the height of the veranda is almost the same as that of the living room floor. Only, the part facing the inner room is tiled on the reference slab surface as in the prior art, so the height is low. Therefore, in recent years, the front porch floor of an apartment or townhouse is often composed of a two-stage configuration with a high living room side and a low interior side.

It is an object of the present invention to provide a sleeve connection embedding structure for embedding air conditioner piping, so that the piping of the separate air conditioner is not exposed to the outside.
