Clina Shaft Unit Study

Abstract

Purpose:

This study has made to measure the effectiveness of Clina Shaft-unit in UAE.

Method:

Install Clina system in the Constructional model Considering the following

elements:

- 4 shaft-units

- Control System.

- Constructional model ( 43.8 m ²). Drawing(1)

- Glass Flats (Windows ,Doors)

- External Walls

- External Walls Directions

- The non-exposed parts to the direct Sun radiation of the constructional

model.

- 2 Split Unit A/C (2 Ton each) –for Consumption Comparison Study

Sample used LG split unit, power input under normal operation 2.4 Kwh and

the maximum power input 4.0 Kwh, in our study we choose the normal

operation.
