             Basics of HVAC System
HVAC system is a basic requirement of a pharmaceutical manufacturing facility. It has different parts those help to maintain the requiredtemperature and humidity in the manufacturing area.
Air conditioning has changed over years, HVAC system is used to control the environment in the manufacturing as well as the storage area of the pharmaceutical facility. 


Heating, Ventilation and Air Conditioning is a system that is used to control the air temperature by controlling the air filtration and the moisture in the air.
This system is used to control the temperature of a designated space with the control of the moisture in the air, supply the area with fresh air by controlling the carbon dioxide and oxygen level.
It alsocontrols the contaminationof airborne particles by regulating the movement of air.
The HVAC system can effectively control the air conditions of a given parameter through heating by adding the thermal energy in an area to increase the temperature; the cooling is done through decreasing the thermal energy in an area to decrease the temperature.
Humidifying is done by adding steam or water vapor in an area to increase therelative humidity while dehumidifying is done through getting rid of the humidity or water vapor in an area.The air is cleaned by removing the smoke, dust or pollens that contaminate the air.
The air is ventilated by maintaining the gas ratio which can be done through adding external fresh air. Lastly, the system controls the air movement that is supplied in a space which ensures that those in the place are comfortable.
The following re the basic components of an HVAC system and the role they play to keep the condition the suitable;
Furnace. This is the largest and the main component of theHVAC system. It heats the air that is supplied the system; this can be done through the heat pump, solar energy, or the burning of the natural gasses. Inside the furnace, there  is a heat exchanger which helps to switch on when the furnace is activated. It pulls the cold air and heats and circulates the air out through the vents.
Thermostat.   The thermostat can either be set manually or programmed in advance to the desired temperature. It is easily visible and accessible part of the system. The thermostat can trigger theheat exchanger or evaporator coil-condensing unitto circulate a space with cold or warmed air.
Evaporator  coilThis helps to cool the heated air. It is connected to the condensing unit which is filled with refrigerant gas. The unit is usually installed outside the room. It pumps the condensed liquid to the evaporator coil which is evaporated to gas again.
Refrigerant lines  This unit carries the refrigerant substance to the condensing unit for vaporization and returns it to the evaporator in liquid form. They are narrow tubes usually resistant from heat and cold.
Ductwork  This unit transports the cooled or the heated air across the room. The ducts are made from lightweight aluminum. The ductwork is connectedwith the vent that transfer cooled or heated air to individual rooms. They are usually located near the ceiling and are fronted with angled slats. The can be manually controlled to regulate the heatingor cooling of space that they are directed.

Requirement of Active and Passive Air Sampling in Controlled Areas

-
Air sampling is a mandatory procedure to be followed in pharmaceuticals to produce the contamination free quality product. What would you say if I ask for the causes the most contamination of products during the manufacture of pharmaceuticals? However, air is another keysource of contaminationthat most pharmaceutical facilitiesoften ignore to take precaution from. Air samplingor air monitoring is essential for Quality Control(QC) purposes especially in companies that manufacture pharmaceutical products in controlled areas or clean rooms with filtered air.Well, what pharmacists, health care practitioners, and microbiologists refer to as air sampling can simply be defined as taking a correct measurement of the practical airborne bacteria, mold, yeast, spores and fungal cells which can be collectively referred to as bioburden in the surrounding air. The two main methods used to sample air are: 1 .Active air sampling/ monitoring 2.Passive air sampling/ monitoring 1. Active Air Sampl

Purified Water Storage and Distribution System Learn about the purified water storage and distribution system and procedure for validation. The purified water is prepared by purified water generation system (Reverse Osmosis System) and collected in purified water storage tank of required capacity and distributed by a centrifugal pump for loop recirculation.At different points of use separate heat exchangeris provided (if required) to bring down temperature of hot circulating water as and when required. There is a back pressure valve in the return line. Instruments and on/off valve are for controlling and monitoring the system  operation and water quality. These are controlled from a centralized control panel consisting of a PLC board. The distribution piping consists of sanitary tubes, fittings, valves with orbital welding and triclover clamp in manufacturing area and for instrument connections. The water through this piping is supplied to various user points and circulated back
