HVAC System in Pharmaceutical Industry

HVAC System in the Pharmaceutical Industry

HVAC is an important part of any pharmaceutical industry. HVAC abbreviated for Heating, Ventilation and Air Conditioning system.
HVAC has different parts that help to maintain the required temperature and humidity in the manufacturing area.
The HVAC system is used to control the environmental temperature and humidity in the manufacturing and storage area of the pharmaceutical industry.
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.
HVAC System

The HVAC system is used to control the temperature of a designated area with the control of the humidity in the air, supply the area with fresh air by controlling the level of carbon dioxide and oxygen. It also controls the contamination of airborne particles by regulating the air movement. 

The HVAC system can adequately control the air conditions of a given parameter through
  • Heating by adding the thermal energy in an area to increase the temperature.
  • Cooling is done by decreasing the thermal energy in an area to decrease the temperature.
  • Humidifying is done by adding steam or water vapour in an area to increase the relative humidity.
  • Dehumidifying is done by getting rid of the humidity or water vapour 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 by adding external fresh air. The system controls the air movement that is supplied in a space which ensures that those in the place are
comfortable. The following are the basic components of an HVAC system and the role they play to keep the condition suitable.
Furnace
This is the largest and main component of the HVAC 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 the heat exchanger or evaporator coil-condensing unit to circulate a space with cold or warmed air.
Evaporator Coil
It 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 to the condensing unit for vaporization and returns it to the evaporator in liquid form. They are narrow tubes usually resistant to heating and cooling.
Ductwork
This unit transports the heated or cooled air across the room. The ducts are made of lightweight aluminium. The ductwork is connected with the vent that transfers heated or cooled air to individual rooms. They are usually located near the ceiling and are fronted with angled slats. It can be manually controlled to regulate the heating or cooling of space that they are directed.
