HVAC systems are milestones of building mechanical systems that provide thermal comfort for occupants accompanied with indoor air quality. HVAC systems can be classified into central and local systems according to multiple zones, location, and distribution. Primary HVAC equipment includes heating equipment, ventilation equipment, and cooling or air-conditioning equipment. Central HVAC systems locate away from buildings in a central equipment room and deliver the conditioned air by a delivery ductwork system. Central HVAC systems contain all-air, air-water, all-water systems.

Weber Comechanics was established in as a research and design entity undertaking development of analytical instruments — pyrometric control devices for resistance welders — which attracted significant interest of engineering experts in the industry. At close cooperation with production plants, it became obvious that many processing areas lack necessary equipment or tooling. In order to increase production efficiency, a unified engineering approach had to be applied to all stages of processing. Eventually, the company has entered into over 20 exclusive representative agreements with internationally acclaimed equipment manufacturers from Europe, South-East Asia and the USA.

Heating, ventilation, and air conditioning
The safe and efficient operation of boilers and domestic water heaters is essential for the smooth operation of most institutional and commercial facilities. But good design practices alone do not ensure safety and efficiency. In addition to good system designs, an ongoing inspection and testing program carried out by a well-trained staff of technicians results in safe and efficient operations. Maintenance and engineering managers who ignore any one of these elements run the risk of compromising not only safety and efficiency but also the operation of the equipment.SEE VIDEO BY TOPIC: How Air Handling Units work AHU working principle hvac ventilation

Romina Ronquillo. Heat exchangers are devices designed to transfer heat between two or more fluids—i. Depending on the type of heat exchanger employed, the heat transferring process can be gas-to-gas , liquid-to-gas , or liquid-to-liquid and occur through a solid separator, which prevents mixing of the fluids, or direct fluid contact. Other design characteristics, including construction materials and components, heat transfer mechanisms, and flow configurations, also help to classify and categorize the types of heat exchangers available. Finding application across a wide range of industries, a diverse selection of these heat exchanging devices are designed and manufactured for use in both heating and cooling processes. This article focuses on heat exchangers, exploring the various designs and types available and explaining their respective functions and mechanisms. Additionally, this article outlines the selection considerations and common applications for each type of heat exchanging device.

Doosan is also making substantial inroads into the eco-friendly power generation business including wind power, ESS Energy Storage System and microgrid. A gas turbine is a piece of equipment that rotates a turbine by using the hot gas produced by burning compressed air and fuel, and is core item of equipment for combined cycle and cogeneration power plants. With the growing interest in environmental preservation and power generation load issues in recent years, it is expected that the demand for gas turbines with high performance, reliability, fuel diversity and toxic emissions reduction will increase. We undertook the national project for the development of a large H-class gas turbine in and plans to develop our own model by

Heating, ventilation, and air conditioning HVAC  is the technology of indoor and vehicular environmental comfort. Its goal is to provide thermal comfort and acceptable indoor air quality. HVAC system design is a subdiscipline of mechanical engineering , based on the principles of thermodynamics , fluid mechanics and heat transfer.
In the simplest systems, the current generated by your system is connected directly to the equipment that it is powering load. However, if you want to store power for use when your system isn't producing electricity, you will need to purchase batteries and a charge controller. Depending on your needs, balance-of-system equipment for a stand-alone system could account for half of your total system costs.
