Air conditioning system having a terminal chest to provide optimal airflow

Abstract

An air conditioning system having a terminal chest to provide an optimal airflow mainly includes a first adjustable baffle in a return air inlet of each terminal chest that is openable to a desired degree to regulate second time return air volume and a corresponding first time air intake volume according to alterations of air conditioning energy requirement of individual air conditioning area. A variable speed air fan motor is provided that can automatically adjust the rotation speed to deliver optimal airflow volume to automatically balance the air conditioning energy supply with the air conditioning load, thereby to save energy and prevent cool air effect, and maintain a desired air quality.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The invention relates to an air conditioning system that has a terminal chest to provide and deliver an optimal airflow volume for each air conditioning area according to airflow and air conditioning energy requirements. [0003] 2. Description of the Prior Art [0004] The conventional air conditioning system has a terminal chest 2 (referring to FIGS. 1 and 2) which delivers heat source (cool air or warm air) provided by a first heat source supply system 1 to one or more air conditioning area AO. The terminal chest 2 of each air conditioning area AO has an air vent 21 which contains an adjustable baffle 211 to control airflow of a first time air intake. An air fan motor 22 sends the air through an air outlet 25 to the air conditioning area AO. The terminal chest 2 has a return air inlet 24 on one side that has a selected cross section to provide a second time return airflow. A setting face panel 23 is provided for sett...

Benefits of technology

[0008] In view of the aforesaid problems occurred to the conventional air conditioning systems, the present invention aims to provide an air conditioning system with a terminal chest to provide an optimal airflow. The terminal chest according to the invention has a return air inlet which contains a first adjustable baffle. The first adjustable baffle can be opened to a desired degree according to air conditioning energy requirement alteration of each air conditioning area to regulate the second time return airflow volume, and also regulate the first time air intake volume of the air conditioning. The terminal chest has an air fan motor of variable speed that can be controlled to rotate at a speed to generate an optimal airflow volume according to the required airflow volume in the air conditioning area when the ambient temperature reaches the set temperature. Supply of air conditioning energy of each air conditioning area can also be regulated to achieve an automatic balance with the air conditioning load. When the ambient temperature of each air conditioning area approaches or reaches the set temperature, and the optimal airflow volume is provided, energy can be saved and cool air effect can be prevented, and a desired air conditioning quality can be achieved.

Problems solved by technology

While this control method is economic and simple, temperature and humidity fluctuate too much in the air conditioning area, and energy control is difficult.

It cannot achieve the desired goal.

Such an approach cannot meet the requirements of the modern time.

While this approach has some improvements in limiting the fluctuation of the temperature and humidity, the temperature of the piping fluctuates and is difficult to reach an optimal balance point when the volume of cooling and hot water changes.

Hence the temperature and humidity in the air conditioning area are difficult to reach a desired condition.

In a low sensible heat loading environment, to reach a desired humidity is difficult to control.

But in the low loading operation, airflow is not sufficient and air circulation in the air conditioning area is undesirable.

In the event of uneven temperature distribution and not adequate external air replenishment, people could feel uncomfortable.

The cool air effect could even impair the health of people who are not physically fit.

Because of the conventional VAV and CAV systems cannot meet the requirement of providing a comfortable condition for users, and the air conditioning system controlled manually consumes a lot of energy, they become a big concern in energy conservation.
