CHILLER COMPRESSORS

Image
 CHILLER COMPRESSORS In HVAC industry, the refrigeration machine that produces chilled water is referred to as a “Chiller”. A chiller package operates either on the principles of vapor compression or vapor absorption. The vapor compression system uses mechanical energy in the form of electric motor to drive the cooling cycle whereas absorption chillers use heat to drive the process. The vapor compression chiller system, which is far more prominent in commercial buildings, consists of four major components: the compressor, evaporator, condenser and expansion device all packaged as a single unit. The classification of vapor compression chiller packages is generally by the type of compressor: centrifugal, reciprocating, and screw being the major ones.                                                        Chillers are the largest consumer of energy in a commercial building and it is therefore important to understand the relative benefits and limitations of various types in order to make t

Building Services

HVAC 

Building Services (MEP):-
                                            It is branch of study where we want to import various services such as Electrical, Mechanical, Plumbing & Fire Fighting in an energy efficient building to get benefit of luxurious life style.  

Energy Efficient Building:-
                                                A building which consume energy in an efficient with respect to cheap  and economic cost to get benefits of luxuries lifestyle. 
                              A building is one which use less water optimize energy efficiency, conserve natural resources generate less wastages & provide healthier for occupancies or resident as compare to conventional buildings.

PSYCHROMETRICS

 PSYCHROMETRICS PSYCHROMETRIC:-                                    Psychometric is the science of studying the thermodynamic properties of moist air. The amount of moisture vapor in the air varies quite significantly under different conditions. When the air is hot, it can contain a large amount of moisture vapor sometimes as much as 5% by volume. When it is cold, its capacity to hold the moisture is reduced. When the temperature of warm air begins to fall, the vapor also cools and, if cooling continues, it will condense into tiny moisture droplets. In the atmosphere this results in the formation of clouds and eventually rain. DEFINITION OF AIR:-      Three basic definitions are used to describe air under various conditions: 1.ATMOSPHERIC AIR:-                                                        It contains nitrogen, oxygen, carbon dioxide, water vapor, other gases, and miscellaneous contaminants such as dust, pollen, and smoke. This is the air we breathe and use for ventilation. 2.

Heat Recovery Ventilation

  HEAT RECOVERY VENTILATION Introduction of Heat Recovery Ventilation(HVR) :-                An HRV is a mechanical ventilation device that helps make your home healthier, cleaner and more comfortable. It does  by continuously replacing the indoor air with fresh outdoor air. Their ability to exchange heat between the supply and exhaust air reduces the cost of heating or cooling of fresh air circulating through the home. HRVs are sometimes called air-to-air heat exchangers because they preheat or cool incoming air using exhaust air.                                                                                      There are many types of HRVs on the market, as well as different installation strategies. That depends on the size of your house, type of heating system and geographical location. Mechanical Ventilation:- The new homes are built to be airtight. This limits the uncontrolled flow of air in and out of the home and reduces heat loss and moisture damage to the building structure.

BASICS OF AIR CONDITIONING

Image
AIR CONDITIONING HVAC HEATING:-   It is form of energy which transfer form one body to another due to change in  temperature. VENTILATION:-  Providing out side air or Fresh air inside the room from outside to improve the indoor Air quality (IAQ) there by removing bad odor  gases called as  ventilation. AIR CONDITIONING:-   It is conditioning  of air according to human comfort zone condition & human comfort  zone criteria as mentioned by ASHRAE (American Society  of  Heating Refrigeration & Air Conditioner Engineer)   Comfort zone temperature  are 76 ℉ / 24 ℃ & 50% RH (Relative Humidity)                               The term Air conditioning can also be defined as conditioning the air by conditioning the temperature humidity air motion, air quality & quantity within the space for satisfying the requirement of the comfortness is known as air conditioning  Application of Human Comfort Zone:- Residential Buildings. Commercial Buildings. Hotels & Restaurants. Supermarke
