Laws of Thermodynamics

 Law's of Thermodynamics


Thermodynamics Laws describe the physical quantities such as Energy, Temperature, entropy that define the Thermodynamics systems at Thermodynamics equilibrium.The laws explain the relation between this quantities
There are four laws of Thermodynamics let's check it out.



1) Zeroth Law of Thermodynamics:-


Zeroth Law state that the when the two bodies are in a thermal equilibrium with the third body, Then that two bodies are in a thermal equilibrium with each other's.

2) First Law of Thermodynamics


The first law of Thermodynamics is a version of law of energy conservation
It state that the total energy of an isolated system is constant,it can be transferred from one form to another form, but can neither be created nor be destroyed.
For a Thermodynamics process without transfer of matter first law is 
Often formulated

3) Second Law of Thermodynamics:-

When two initially isolated body separate but in a nearby region,each in Thermodynamics equilibrium with itself not necessarily with each other, are then allowed to interact.Then will eventually reach a mutual Thermodynamics equilibrium.The sum of entropies of the initially isolated system is less than or equal to the final combination.

4)Third Law of Thermodynamics:-

This law indicates that as a system's temperature nears absolute zero (0 Kelvin), its entropy approaches a minimum level. In essence, it suggests that reaching absolute zero in a finite number of steps is unattainable, and at absolute zero, the system achieves a state of perfect order characterized by zero entropy.

How to control Temperature and Humidity in Air Handling Unit

  How to control Temperature and Humidity in Air Handling Unit Overview Air Handling unit is a system used to supply temperature and Humidity controlled filtered air to the cleanroom. For air filtration various types of filters are used in AHU. And for temperature and Humidity controlling cooling and heating coils are provided in AHU. Goals Control the temperature of air used in the cleanroom  Control the humidity of air used in cleanroom  Air filters Specifications    The air Handling unit consists of Air filter  Cooling coil Heating coil Air blower HEPA Filter  Controlling of Temperature and Humidity  By Cooling Method  The cooling coil recirculates the chilled water having temperatures between 4°C to 6°C. This chilled water comes from the Chiller through centrifugal pumps. When we start the Air Handling unit blowers sucks the air through the pre filters of the air Handling unit. When blowers sucks air, it passes through the cooling co...

Why ice forms at cooling coil and Suction line in Refrigeration system

 Why ice forms at cooling coil and Suction line in Refrigeration system       it's all about the relationship between a temperature and pressure and how the pressure affect the boiling point of the refrigerant. As the pressure of refrigerant increases then the temperature and boiling point also increases,  when pressure decreased temperature and boiling point also decreases. Refrigeration and air conditioning systems take use of it to cool the air or liquid.   Normal Refrigeration System      In normal refrigeration system compressor compresses the refrigerant which causes the increase in pressure and temperature of refrigerant. The hot vapour refrigerant pass through the condenser in condenser heat exchange happens and refrigerant condensate into liquid forms.Before entering in the evaporator high pressure liquid refrigerant pass through the expansion of valve. The actual device used depends on the Refrigeration system but capillary t...

HVAC Validation In pharma Industries

HVAC VALIDATION As per ISO guidelines for HVAC validation. In HVAC Validation  below points are determined and validated that they are in within range as per designed which will pass the respective ISO standard class acceptance criteria. 1)Air velocity and CFM calculation 2)Air changes per hour 3) Installed filter leakage test 4) HEPA filter integrity test 5)Air flow pattern test or smoke test 6)Partical count test 7)Total variable count 8) Temperatur and pressure monitoring 9) Temperature and Humidity recovery test 10) Fresh air calculation All this points are determined recorded in documents.All this validation process done by validation contractors under observation of respective company Engineer. 1) Air velocity and CFM calculation :-   - Scan the area of the HEPA filter with probe of anemometer 6 inches from the filter face. - For accurate velocity take the velocity of air at five place of filters ( Four corners and centre of filter) - Record the air velocity i...
