I am a doctorate in mechanical engineering at Tishreen University (thermal machinery). I have researched the use of one of the alternative types of energy for heating and air conditioning buildings in the most successful and least expensive ways .
I am always aware of everything related to heating, air conditioning and sustainable development
I practiced the teaching profession in the Faculty of Mechanical Engineering at Tishreen University (fifth- and third-year students specializing in heating and air conditioning), and I acquired leadership skills in transferring information and instilled in me the desire to achieve more with passion and will. It is an experience rich in knowledge and communication with the capabilities of young people, familiarity with their educational problems, and working within a collective team spirit.

The Effect of Geometric Factors and Groundwater Velocity on Improving the Performance of a Finned Helical Tube for a Heat Pump (Groundwater-Air) in Damsarkho
Improving the heat exchanger of the heat pump (air-groundwater) used for heating and air conditioning purposes is what will improve the efficiency of the heat pump more than improving the rest of its components. Since the groundwater in Damsarkho can be used in a heat pump for heating and air conditioning purposes, it was necessary to improve the exchanger that will be placed in these water wells. With the help of the laws of heat and mass transfer, a number of design calculations were performed to calculate the effect of factors that included: (fin thickness, change Shape the fins into round and square with different diameters and coil curvature ratio. And other factors directly affecting the convective heat transfer coefficient for water and Freon, which included: (groundwater flow, groundwater velocity, coefficient of friction and pressure drop). After obtaining the results, they were presented, using the Excel program, in tables and represented in graphs.
The results showed that the priority in improving the overall heat transfer coefficient of the spiral coil heat exchanger is to increase the groundwater velocity by an increase of 63.3%, then comes in second place by changing the shape of the spiral fins to 7.34 squares. %, then to circles: 6.9%, then to curvature ratio: 3.8%, while changing the thickness of the fins did not have a significant effect.
