Radiation and air supply composite structure

Abstract

The invention relates to a radiation and air supply composite structure which comprises a unit body, a jet flow air supply terminal and a radiation terminal, wherein the jet flow air supply terminal and the radiation terminal are arranged on the unit body in a composite mode. The jet flow air supply terminal is arranged on the upper portion of the unit body and connected with an all-air air supply system. The radiation terminal is arranged on the lower portion of the unit body and connected with a radiation system through a water supply pipe and a water return pipe. The unit body is mounted on a building floor, and the mounting height covers the activity range of personnel. According to the radiation and air supply composite structure provided by the invention, a building space is divided into a non-air-conditioning area located on the upper portion of the jet flow air supply terminal and an air-conditioning area located on the lower portion of the jet flow air supply terminal through jet flow air supply of the jet flow air supply terminal, the layered air-conditioning effect is achieved, and compared with the prior art, the radiation and air supply composite structure has the advantages of reducing air-conditioning energy consumption of high and large space buildings, lowering cost and the like.

Description

technical field [0001] The invention relates to a technique for improving indoor heat and humidity environment in a tall space, in particular to a radiant air-supply composite structure. Background technique [0002] In recent years, the number and scale of tall and large space buildings such as airport terminals and high-speed railway stations have developed rapidly, which has also brought about the problem of high building energy consumption of tall and large space buildings. Due to the large space, large number of people, long running time, and large area of ​​glass curtain walls in this type of building, the energy consumption of the air conditioning system is high and the operating cost is high. It is necessary to adopt a reasonable air conditioning method to reduce the energy consumption of the air conditioner while improving Indoor hot and humid environment. [0003] For tall and large spaces, the traditional air supply methods are side air supply such as nozzles and...

AI Technical Summary

Problems solved by technology

Among them, the air supply mode on the side of the nozzle has a limited range and needs to meet the requirements of construction and decoration, especially in the face of the increasing volume and span of various large-scale traffic buildings, the air supply distance often reaches 80-90m, which is easy The range of the spray nozzles on both sides cannot meet the demand; and the air supply method at the top of the nozzle will bring the waste heat from the upper part of the large space into the personnel activity area, which will increase the energy consumption of the air conditioner

[0004] Therefore, for tall and large space buildings, such as terminal buildings, high-speed rail stations, etc., the current common practice is to set up air supply unit columns, electromechanical compass boxes, etc. to solve the air supply problem, that is, through the form of equipment units, the information Screen, fire hydrant, vertical air conditioning box, etc. are integrated together, and jet air outlets are arranged on the upper part of the compass box to meet the air supply in large spaces. However, due to the integration of various mechanical and electrical equipment, this kind of design has defects such as bulkiness and difficulty in coordinating with interior decoration; If only the traditional air-conditioning system is used, that is, air ducts supply air to adjust the indoor environment, problems such as excessive air duct size may occur in tall spaces, and only relying on the air system for heat exchange is not conducive to energy saving

[0005] In order to reduce the disadvantages of traditional air conditioning systems, radiation systems are often used in tall and large space buildings in severe cold or cold regions. Generally, cooling and heating are provided through floor radiation, ceiling radiation, etc., but this method has a large laying area and high equipment investment.
