Static pressure calculation in HVAC design

Image
  What do you mean by Static Pressure? Static pressure describes the resistance experienced by air as it travels through an  HVAC system . In other words, it is the pressure a fan must overcome to move air through ducts, as needed for heating, ventilation and cooling. Static pressure and airflow are the two main aspects that determine the operating point of a fan, as well as power consumption. Various types of HVAC equipment establish an airflow through ducts, and two common examples are air-handling units (AHU) and packaged rooftop units (RTU). These pieces of equipment are designed to deliver a specific performance in terms of airflow and velocity. For an HVAC system to operate normally, equipment capabilities must match the needs of the air duct system. In particular, air handling systems must be capable of overcoming the static pressure. Other parameters considered by HVAC designers include the installed cost, operating expenses, maintenance, noise and vibration. Air Duct D

A Brief look into IPLV/NPLV

Image
The Integrated Part Load Value (IPLV) is a performance characteristic developed by the Air-Conditioning, Heating and Refrigeration Institute (AHRI). It is most commonly used to describe the performance of a chiller capable of capacity modulation.  Unlike an EER (Energy Efficiency Ratio) or COP (coefficient of performance), which describes the efficiency at full load conditions, the IPLV is derived from the equipment efficiency while operating at various capacities. Since a chiller does not always run at 100% capacity, the EER or COP is not an ideal representation of the typical equipment performance. The IPLV is a very important value to consider since it can affect energy usage and operating costs throughout the lifetime of the equipment. Energy codes such as ASHRAE Standard 90.1 specifies minimum values for the equipment. Fig 1: Water Cooled Chiller The IPLV is calculated using the efficiency of the equipment while operating at capacities of 100%, 75%, 50%, and 25%. For the purpose

How MEP Coordination adapts BIM?

Image
In the construction industry, new technology is most often embraced. For AEC (architectural, engineering, construction) professionals and firms, the development of the Building Information Modelling technology has proved to be a boon. Mechanical, Electrical and Plumbing or MEP coordination is an integral part of the constructability review process and this process is easily facilitated utilizing BIM. MEP services are a crucial part of a functioning building structure. They include gas piping, fire protection, data systems, pneumatic tubing, etc. Coordination of MEP services ensures that the layout of these services does not clash with each other or with the structural or architectural disciplines. Before beginning actual construction, all coordination challenges must be addressed. When it comes to the coordination of MEP, it has always been a challenge to stay within budget. Also, the conventional process of MEP is not very efficient. There is always the risk of human error in an exte

Why do you need MEP Engineering Consultants Help Your Company?

Image
  MEP stands for mechanical, electrical, and plumbing engineering and experts from these technical controls are who design the systems that make building interiors suitable for people. These building systems must be defined and installed correctly to achieve their purpose, and must also be maintained at frequent intervals to stay under optimal operating conditions. Although MEP consultants can offer you a broad range of engineering services, they usually accomplish one of the following purposes: Making sure the building systems in new construction are outlined and fitted properly. Knowing insufficiencies in existing buildings, and introducing measures to improve them and improve performance. In a way, MEP consulting can be deemed an investment - you pay for an expert service to make sure your building systems perform optimally during their service life. This yields substantial financial benefits such as more economical operating costs and enhanced productivity, along with qualitative

Prompt Consulting: MEP Services and their Significance in Construction Business

Image
MEP Engineering Services  are some of the crucial services that are needed for building projects by architects and engineers. MEP systems are popular among AEC professionals for their technicalities and complexities, and their modeling requires quite an effort. Professional modelers of service providing company must be involved in the execution of  MEP services . MEP is a sunshade word for mechanical, electrical and plumbing systems of the construction. And therefore when we say MEP modeling, these services are performed for developing mechanical, electrical, and plumbing models for designing MEP models the involvement of mechanical engineer, electrical engineer and plumbing engineer is extremely important.  MEP engineering consultants  are technical experts in this region and they know it very well that how to deal with the complexities of these projects. Before executing modeling services for mechanical, electrical, and plumbing systems specific layouts are generated for MEP compo

Top 3 Benefits of Outsourcing CAD Services to India

Image
Outsourcing was initially recognized as a viable business model in the 90s. It enabled companies to free up some resources and develop other aspects of business all the while saving up on costs. Furthermore, outsourcing is an excellent way to enhance inter-market relations on a global level and promote free-market economies. As the world is becoming technologically superior everyday AEC firms are also going the digital way. One of them is through CAD software which enables companies to plan, execute and produce their plans in a single program. Major difficulties that are encountered involve cost and time restrictions as well as lack of experienced professionals. The answer to these difficulties lies in outsourcing. India is one of the prominent contenders when it comes to Outsourcing CAD Services . Top 3 Benefits of Outsourcing are listed below: Better Quality with Cost affordability: One of the major benefits of outsourcing your CAD Services is that India offers a magnitude of extre
