Two-way equally-divided fresh air induced dry coil pipe air conditioner device

Abstract

The invention discloses a two-way equally-divided fresh air induced dry coil pipe air conditioner device. The two-way equally-divided fresh air induced dry coil pipe air conditioner device comprises afresh air main pipe, multiple fresh air branch pipes, an air hose, a fan coil pipe and a tuyere. The air supply end of the fan coil pipe communicates with an air supply opening of the tuyere throughthe air hose. The fresh air branch pipes are arranged on the fresh air main pipe. The output ends of the fresh air branch pipes communicate with the air hose. Compared with the prior art, by the adoption of the two-way equally-divided fresh air induced dry coil pipe air conditioner device, fresh air and the air supplied by the fan coil pipe can be uniformly mixed, the air quality is high, the costis low, and the structure is simple.

Description

【Technical field】 [0001] The invention relates to an induced air supply mode in which the fresh air is evenly divided into two channels, in particular to an air supply mode in which the fresh air and the air supplied by the fan coil unit are fully and evenly mixed in a fan coil unit adding fresh air system. 【Background technique】 [0002] Fan coil plus fresh air air conditioning is a main form of air-water air conditioning system, and it is also the most common air conditioning method used in civil buildings in my country. The main advantage of the fan coil unit plus fresh air air conditioning system is that it can control the cooling and heat supply through the fan coil unit to control the temperature of the local area, which can meet the different temperature requirements of the air-conditioned rooms. Sufficient air volume is the guarantee of comfort in the air-conditioned space. Insufficient air volume will lead to low supply air temperature, uneven indoor temperature fie...

AI Technical Summary

Problems solved by technology

This air supply method has the following problems: 1. The actual supply of indoor fresh air varies with the speed of the fan in the fan coil unit. The closer the fresh air outlet is to the fan coil unit, the more obvious this change is; 2. When the fan coil unit When the duct fan stops running, the fresh air may be blown out from the return air outlet with the filter, which is not conducive to indoor sanitation; 3. Since the fresh air volume occupies a part of the air supply volume of the fan coil unit, it weakens the fan coil unit’s ability to process indoor return air. ability

This air supply method improves the shortcomings of the previous method to a certain extent, but there are some disadvantages: 1. Since the system mode is still parallel operation of the fresh air system and the air conditioning air supply system, it is difficult to balance the pressure of the air supply and fresh air, Especially when the speed of the fan in the fan coil unit changes, it directly affects the supply of fresh air; 2. When the fresh air is mixed with the air supplied by the fan coil unit, there is often uneven mixing, resulting in poor air quality

But his disadvantage is that there are at least two air supply outlets in the room, which will have some impact on the decoration of the indoor ceiling.
