Deep breathing is good for everybody, and should be practiced for optimal lung expansion.aking the world better, one answer at a time. when the diaphragm contracts down it flatten the thoracic cavity floor thus expanding the lungs in a inferior direction.
The heating and ventilating industry installs innovative systems and new technologies such as air and ground source heat pumps to make buildings as energy efficient as possible. To do this, the industry requires highly-trained engineers who have the skills to install increasingly complex systems. Heating and ventilating engineers may be involved in a diverse range of duties: Pipework and Ductwork Installers use their skills to cut, form, weld and join a wide range of materials used within a heating and ventilating system.
Glossary of HVAC terms. HVAC (heating, ventilation, and air conditioning) is a major subdiscipline of mechanical engineering. The goal of HVAC design is to balance indoor environmental comfort with other factors such as installation cost, ease of maintenance, and energy efficiency.
