What are the advantages of refrigeration?
Advantages of Refrigeration System:
- The basic advantage of air refrigeration is the working substance which is always available in the atmosphere.
- The refrigerant (air) is free of cost and the system is simple to understand.
- The refrigerant keeps the container cool by breaking the bacterial involvement.
What is laboratory refrigerator?
The refrigerator in a laboratory is one of the most important equipment. Its function is to maintain, in a controlled environment (refrigerated space), various fluids and substances, so that they are kept in good condition the lower the temperature, the lower chemical and biological activity.
What checks are necessary for a medication fridge and why?
Recording temperature
- record the temperature of the fridge daily.
- you should record minimum, maximum and current temperatures, using a minimum/maximum thermometer.
- the thermometer should be reset after each reading.
- make sure that your staff understand how to read and reset the thermometer and why this is necessary.
What is the working principle of a refrigerator?
Refrigerators work by causing the refrigerant circulating inside them to change from a liquid into a gas. This process, called evaporation, cools the surrounding area and produces the desired effect. You can test this process for yourself by taking some alcohol and putting a drop or two on your skin.
What is the necessity and application of refrigeration systems?
Now-a-days refrigeration has become an essential part of food chain- from post harvest heat removal to processing, distribution and storage. Refrigeration has become essential for many chemical and processing industries to improve the standard, quality, precision and efficiency of many manufacturing processes.
What is refrigeration system?

When should fridge temperatures be checked?
Your refrigerator should be able to keep the food at a temperature between 1 and 5°C and frozen food should be stored at -18°C or below. Fridges should be checked at least twice per day. We would always recommend a check is carried out as soon as possible at the beginning of your working day.
How often should medication fridge temperatures be checked?
daily
The temperature of the medicine refrigerator should be monitored daily when it is in use – a maximum/minimum thermometer is recommended for this purpose. The thermometer should be read and reset daily, and the maximum and minimum temperatures recorded.
Why do you need a refrigerator and freezer in a laboratory?
When you work in a scientific or medical laboratory, you need a safe and secure place to store the different materials, samples, and products you work with. Lab refrigerators and freezers are the dependable solution to temperature control and preservation of these resources.
What is the function of the refrigerator?
Its function is to maintain, in a controlled environment (refrigerated space), various fluids and substances, so that they are kept in good condition the lower the temperature, the lower chemical and biological activity. To achieve this it is required that the internal temperature of the refrigerator be lower than the ambient temperature.
What are the standards for laboratory refrigerators?
Additional standards include A-A-52150 which defines technical and quality assurance requirements for a non-food, explosion proof, laboratory refrigerator and BS 4376-1 for electrically operated blood storage.
Do laboratory reagents need to be refrigerated?
Laboratory Reagents. The majority of reagents used for laboratory testing are temperature sensitive, with most requiring routine refrigeration. A small subset of materials require freezer, or below freezer-level conditions (ranging from freezing to 70 degrees below freezing). Without refrigeration, most reagents will deteriorate within hours.
