Multi-pipe air inlet air mixing cabin

Abstract

The invention relates to a multi-pipe air inlet air mixing cabin which comprises a shell, an indoor air inlet pipe set, an outdoor air inlet pipe set and down draught preventing valve plates. An air mixing region and a mixed air outlet are formed in the shell, holes allowing indoor air inlet pipes and outdoor air inlet pipes to be inserted are formed in the shell, the indoor air inlet pipe set comprises the indoor air inlet pipes, the outdoor air inlet pipe set comprises the outdoor air inlet pipes, one end of each indoor air inlet pipe and one end of each outdoor air inlet pipe are arranged in the air mixing region, the other end of the corresponding indoor air inlet pipe and the other end of the corresponding outdoor air inlet pipe are arranged outside the shell, all the ends, in the air mixing region, of the indoor air inlet pipes and all the ends, in the air mixing region, of the outdoor air inlet pipes are provided with the down draught preventing valve plates, the down draught preventing valve plates are connected and fixed to the indoor air inlet pipes and the outdoor air inlet pipes through hinges, and the hinges are located in the centers of openings of the indoor air inlet pipes and the centers of openings of the outdoor air inlet pipes. Air inlet amount is disintegrated through multi-pipe air inlet, and control over air mixing proportions and air mixing temperature is facilitated; the problems of air leakage and down draught can be solved through the tiny air inlets and the down draught preventing valve plates.

Description

technical field [0001] The invention belongs to an air mixing bin for air conditioning equipment, in particular to a multi-pipe air inlet mixing bin. Background technique [0002] The air mixing chamber can also be called the air mixing chamber or the air mixing device. It is an important part of various fresh air devices. The fresh air device has two main functions, one is to change the air, to remove the indoor turbid air and introduce the fresh air from the outside. The second is to adjust the temperature and use the temperature of the outdoor natural wind to improve the indoor air temperature. Fresh air devices are currently mainly used in large-scale building central air-conditioning and high-temperature boilers and furnace smelting. Among them, the efficiency of ventilation and temperature adjustment, and the amount of energy consumption are the main evaluation indicators for measuring fresh air devices.

AI Technical Summary

Problems solved by technology

[0003] There are still many shortcomings in the existing air mixing chamber technology. First, the air inlet and outlet are single, and the air output is small; second, the control of the air intake is mostly realized by electric dampers, which is not conducive to intelligent control; third, The utilization rate of natural wind is not high, and it mainly relies on air compressors for cooling, which consumes a lot of energy

In addition, most of the air mixing chambers used in the fresh air system are complex in structure or bulky, which is not conducive to manufacturing and maintenance, and the scope of application is limited
