For example, room increases greatly affect the ventilation work, including the overall cooling and warming of your home or business building. Indeed, even 200 square feet of expansion may require critical changes to your ventilation work framework.  To guarantee you take care of business, it's essential to comprehend what ventilation work is, the job it plays and its key segments. Equipping yourself with the data in regards to the cycle won't just assist you with taking care of business the first run through yet additionally guarantee your undertakings run all the more easily. This guide will assist you with seeing more about HVAC ventilation work.  The Basic Function of the Duct System  A ventilation work framework is intended to disseminate wind current from your HVAC hardware to your whole home or business building. This incorporates the ai...

Efficiency of Process Chiller    Chiller is a machine that removes heat from water or air via vapor-compression cycle or vapor-absorption cycle.This cooled water or air further used for cooing purpose for equipment or for Chillers are widely used in every field like in industry, commerce and in building air conditioning.Air conditioning and chillers both are the heat pumps, chiller uses water for heat exchange media and air conditioning uses air . After the heat exchange process waste heat exhausted in ambient or recovered it for heating purpose.     Chillers efficiency depends on the energy consumed by the chiller and cooling delivered by the chiller in that consumed energy.The chiller efficiency always measured in "COP" which stands for   Coefficient Of Performance.    Coefficient of performance is just simple, it is the ratio of refrigeration effect produced by the chiller to the energy consumed by the chiller to produce that refrigeration effect.B...

  Cleaning Of HVAC unit and PPM of HVAC What is HVAC ?    Hvac system is a system which is used to provide indoor air comfort by heating, ventilation and air conditioning.  The main purpose of hvac system is to provide comfort and good quality filtered air. HVAC air Filters    To provide good quality filtered air, HVAC system uses a different types of air filter in a air handler as per the area which is to be air supplied.In pharmaceuticals industries air filtration quality is very precisely maintained by using Pre filters, fine filters, HEPA filters and return air filters .    Pre filters size is varies depending on the company and criticalness of area. Which is ranging from 20 micron or 10 micron and both filters also used in one frame as Double filters.    Fine filters are used in Air handler after the pre filters. The micron size of fine filters are 5 micron or 3 micron.    After that Pre and fine filters hepa filter are...

HVAC TECH  Building Management System    Today, it is quite difficult to manually control a building's equipment, utilities, power, lighting and other energy resources  without a reliable and effective control system that ensures the comfort and safety of the people who live and work in the building. Moreover, it is difficult to maintain the equipment and utilities and optimize the resources used. For this reason, building management systems are used to control all systems and energy efficiently and effectively. What is Building Management System? A Building Management System is a system for controlling, managing and monitoring devices such as: air conditioning system, lighting system, heating system, ventilation, power supply, door locks, etc.  A Building Management System is a computer-based system that is installed in a building. Building Management System hardware and software were originally developed in the 1960s. Over the years, the IT infrastructure for ...

  Common Issue's In Refrigeration And HVAC System  The Refrigeration systems not only provide us a comfort air and sufficient temperatures but also provides us productivity, energy Bill's and product safety.  The Refrigeration system runs almost continuously all time with providing us comfort air and temperature. Doing a sufficient preventive maintenance on scheduled basis to keep Refrigeration in proper working condition and efficient in all time. Some time we'll maintained and operational system may give us some operational problems. Then knowing the problem is big challenging for us, because the Refrigeration systems are very critical.  Below are the some common problems with its causes in Refrigeration system which we should have to aware about it. Room Temperature High or worm:- Causes  Low Refrigerant or a under charged refrigerant level in system. Incorrect oil and refrigerant ratio can cause a increased Suction temperature of compressor.  Dirty ...
