Abstract

Provided is a blowout port for low temperature air conditioning free from the generation of dew condensation even in a low temperature air conditioning system, having high conditioned-air diffusing function, and exercising superior air conditioning function. A plurality of gas flow channels 10, 11 are formed by coaxially arranging a plurality of cone members 7, 8, 9 respectively composed of square cylindrical basic end parts 7a, 8a, 9a and square conical enlarged parts 7b, 8b, 9b, at the blowout port 1 for low temperature air conditioning. An airflow diffusing member 12 wider than an opening area 7s of the basic end part 7a is mounted on a position opposite to the basic end part 7a in an area surrounded by the enlarged part 7b of the central cone member 7. A central airflow squeezing rate P is determined to be two times an average value of a main airflow squeezing rate Q, when a rate of a minimum clearance area 7t to the opening area 7s is the central airflow squeezing P, and rates of minimum opening areas 10t, 11t to the opening areas 10s, 11s are the main air flow squeezing rate Q.

Description

technical field [0001] The invention relates to an exhaust port for low-temperature air conditioners, which has a structure formed by coaxially arranging a plurality of cone parts in multiple layers. The enlarged diameter part (diameter part). Background technique [0002] The air-conditioning equipment for cooling and heating in the building generally has: air-conditioning pipes, which are installed in the ceiling of the building, and are used to transport the conditioned air adjusted to a specified temperature by the air conditioner to the destination; and air-conditioning exhaust pipes. The opening is arranged on the surface of the ceiling or on the wall, and is used to discharge the conditioned air conveyed through the duct for the air conditioner into the room. [0003] As a kind of such an air-conditioning exhaust port, the technique shown in FIG. 7 is known, that is, a wind starter type air-conditioning exhaust port in which the exhaust opening 91 is arranged on the ...
