Displacement ventilation air conditioner room air supply device and method

Abstract

The invention discloses a displacement ventilation air conditioner room air supply device and method. The air supply device comprises an air supply system, an air supply opening is formed in the lowerportion of the side wall of an air conditioner room, and an air return opening is formed in the top of the air conditioner room; and the air supply system comprises an axial flow fan and an air supply nozzle, the axial flow fan comprises an axial flow fan motor, the air supply nozzle is connected with the axial flow fan through a spiral hose and a straight pipe which is connected with the spiralhose, and a wind speed and air volume adjusting valve is arranged on the straight pipe. The displacement ventilation air conditioner room air supply method comprises the following steps that 1, freshair is sent into the air conditioner room from the air supply opening to form a fresh air layer; and 2, the fresh air in the fresh air layer enters the air supply system under the suction effect of the axial flow fan and is sent out by the air supply nozzle. According to the displacement ventilation air conditioner room air supply device and method, acting areas can be adjusted freely along with changes of room division or positions of an indoor table / working table, the action range is flexible, a comfortable and healthy hot environment can be created for indoor personnel at a higher room background temperature, and the energy consumption of an air conditioner is effectively saved.

Description

technical field [0001] The invention belongs to the technical field of displacement ventilation, and in particular relates to an air supply device and method for a displacement ventilation and air-conditioning room. Background technique [0002] With the increasing energy, health and environmental issues, how to create a healthy, comfortable and low-energy indoor environment will become the main task of air conditioning system design and operation. In general, conventional air distribution methods used in air-conditioned rooms can be roughly divided into three categories: hybrid ventilation systems, displacement ventilation systems, and personalized (station) air supply. [0003] Mixed ventilation is a widely used traditional ventilation method. It uses mechanical ventilation as the main power, and uses its high wind speed to send low-temperature air through the top of the room, so that the air flow can be fully mixed with the indoor air, and the residual heat in the room ca...

AI Technical Summary

Problems solved by technology

But in practice, it is necessary to configure nozzles and air ducts for various room layouts, or it is not easy to achieve, or the cost is too high

In addition, the air supply pipes of the personalized air supply system are usually placed in the raised floor, which limits the flexibility

If the room is re-divided, the decoration is updated, or the position of the workbench is moved, the pipeline needs to be re-arranged, causing additional waste
