Abstract
The invention comprises a cabinet, in which is disposed an air duct with an air intake at one end and an air blowing port at the other end. In the air duct is disposed an induction room with an opening via a baffle and on the side of the cabinet is set an induction port in communication with the induction room. In the air duct between the induction room and the air intake is disposed a throttle, one end of which is connected with a side wall of the air duct and the other end is located between the outside of the induction room and the inner wall of the air duct. After the primary air enters into the air intake, the throttle is used for changing its flow velocity and flow rate to produce a negative pressure at the opening of the induction room for inducing the room air into the induction room through the induction port to mix with the primary air. The mixed air flow is blown out through the air blowing port.
Description
Technical field
The present invention relates to air-conditioning technical, relate in particular to the central air-conditioning variable air volume system, particularly a kind of induced blast-variable adjusting mechanism at end of air conditioner.
Background technology
In the prior art, the terminal control device of central air conditioner system needs device air diffuser or accessory fan just can carry out the air quantity adjusting, and air diffuser the cold airflow sinkage can occur when low discharge, influence indoor comfort degree, and simultaneously, accessory fan also can produce noise.
Summary of the invention
The purpose of this invention is to provide a kind of induced blast-variable adjusting mechanism at end of air conditioner, described this induced blast-variable adjusting mechanism at end of air conditioner will solve the terminal control device of central air conditioner system in the prior art needs device air diffuser or accessory fan just can carry out the technical problem that air quantity is regulated.
This induced blast-variable adjusting mechanism at end of air conditioner of the present invention is made of a cabinet, be provided with the air channel in the described cabinet, wherein, one end of described cabinet is provided with air inlet, the other end of described cabinet is provided with air outlet, be provided with an induction room by dividing plate in the described air channel, described induction room has an opening, described opening is towards described air inlet, the side of described cabinet is provided with an induction port, described induction port is communicated with described induction room, be provided with an air door in the air channel between described induction room and described air inlet, one end of described air door is connected with a side inwall in air channel, and the other end of described air door is between the outside and air channel inwall of induction room, and described air door is parabolic shape in the vertical cross-section through the air channel axis.
Further, described air channel is provided with homogenizing plate in the air outlet end.
Further, described cabinet is provided with an air outlet at least in the side of air outlet end.
Operation principle of the present invention is: the air inlet that at first enters cabinet through the primary air of air-conditioning system processing, air door changes the flow velocity and the flow of primary air, can produce a negative pressure at the opening of induction room simultaneously, negative pressure-induced room air enters induction room by induction port, and room air mixes at induction room and primary air.Mixed air communication is crossed air outlet and is blown out.
The present invention and prior art contrast, and its effect is actively with tangible.The present invention is not needing under the special air diffuser or the situation of accessory fan, just can realize the adjusting of throttling range from 20% to 100%, sufficient air motion and thermal comfort can also be kept, and the cold airflow sinkage of air diffuser when low discharge can be eliminated.Operating pressure of the present invention is low, can carry out recuperation of heat in heat pattern, and static pressure can also be converted into the useful energy of inducing, and makes system can adopt a wind of low temperature.The present invention has eliminated the heat of low-level or radiation effectively, and noise is little, and energy consumption is low.
Concrete, the present invention is in refrigeration mode, and the induced blast-variable adjusting system has three characteristics that are better than other variable air volume systems:
(1) can adopt low-temperature primary air (being not less than 9 ℃), allow the designer just can reach same refrigeration duty with the less air amount.Reduced the size of pipe-line system and relevant airhandling equipment simultaneously, can provide more practical space for the user.
(2) can under the prerequisite of not damaging thermal comfort, will regulate than being transferred to 20%, thereby reduce requirement, and allow the AHU of adjustable speed under than the littler air quantity of conventional variable air volume system, to work air mass flow.Be particularly useful under sub-load and nobody situation.
(3) when minimum air output, can as other existing control device, not produce air immobilising " dead band ".And can offer the enough air in room, and make the room that enough air movements be arranged, guarantee occupant's comfortableness.
In refrigeration mode, traditional variable air volume system only can keep indoor thermal than being adjusted to 50%-60% with regulating.This just shows that heating must reach the 50%-60% of heap(ed) capacity again.It is the very low and consumes energy of efficient that the bigger primary air of flow is heated again.And the present invention only heats induced blast-variable adjusting again and need reach 20% of heap(ed) capacity.
