What is Refrigeration System?

 What is Refrigeration System?






    Refrigeration is a process of moving heat from one place to another by the use of Refrigerant in a closed cycle. Oil management, gas and liquid separation, subcooling, superheating, desuperheating, piping of refrigerant gas or liquid, and two phase flow are the parts of refrigeration system. The refrigeration system used widely in various types of ues like in air conditioning, industrial Air Conditioning, commercial Refrigeration and industrial Refrigeration. This blog focuses on the system that uses halocarbons( halogenated hydrocarbon) as a refrigerant. The most commonly used halogen refrigerant are chlorine(Cl) and fluorine(F).
      Halocarbons refrigerant are mainly classified in four groups 

1)chlorofluorocarbon(CFCs), which contains chlorine, fluorine, carbon.

2)Hydrochlorofluorocarbons(HCFCs) which consists of carbon, hydrogen, Fluorine, chlorine.

3)Hydrofluorocarbons(HFCs), which contains hydrogen, fluorine, carbon.

4) Hydrofluoroolefins(HFOs) which are HFC refrigerant derived from an alkene (Olefin, i.e., an unsaturated compound which is having atleast one carbon-to-carbon double compound)

   Desired characteristics of halocarbons refrigerant are include.

- Year round operation, regardless of outdoor ambient condition.

-Possible wide load variations( 0 to 100% capacity) during short periods without series disruption of the required temperature levels.

-Frost control for continuous performance application.

-Oil management for different refrigerant under the varying load and temperature.

- The wide choice of heat exchange method (i.e., dry expansion, liquid overfeed or flooded feed refrigerants) and use of secondary coolant such as a salt brine, alcohol, glycol and carbon dioxide

- System efficiency, maintainability and operating simplicity.

  The successful and efficient Refrigeration System depends on the piping design and the understanding of required accessories.

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...

AIR FLOW, AIR VELOCITY, ACPH, AHU CAPACITY

Air Changes per Hour AIR VELOCITY AND ACPH OF ROOM OR AREA   Procedure to be followed: Air Velocity Measurement and Calculation of Air Changes: Objective : To demonstrate  that the   air system is balanced and capable of delivering air velocities and providing number of air changes per hour in the respective rooms as   per requirement. Equipment to be used: Hotwire Anemometer or capture Hood Pre Requisite: Air Volumes through supply and return grills and filters should be adjusted as per the design requirement of Air Change Rate and Differential Pressure. Test Method : Ensure that the Supply blower of the AHU is "ON" prior to the start of the observations. For compliance of air change rate, velocity to be measured at 5   different locations to below the each terminal or Grill (Four Corners and center) with the help of calibrated Anemometer. Calculate the   average  velocity of the air coming from Plenum HEPA filter / supply air grill. Calculate the air...

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...
