Refrigeration System

Refrigeration is a general term. It describes the process of removing heat from spaces, objects, or materials and maintaining them at a temperature below that of the surrounding atmosphere. To produce a refrigeration effect, the material to be cooled needs only to be exposed to a colder object or environment. The heat will flow in its NATURAL direction-that is, from the warmer material to the colder material. Refrigeration, then, usually means an artificial way of lowering the temperature. Mechanical refrigeration is a mechanical system or apparatus that transfers heat from one substance to another.
It is easy to understand refrigeration if you know the relationships among temperature, pressure, and volume, and how pressure affects liquids and gases.



Purpose of use:

  • Foods of different kinds should be wrapped separately or stored in containers with lids to prevent cross-contamination in the refrigerator;
  • Always remember to place cooked food above raw food in the same refrigerator, i.e. ready-to-eat food or cooked food should be kept in the upper compartment while rawfood should be stored in the lower compartment of a refrigerator.
  • Ensure the temperature of the refrigerator to be kept at less than 5°C and the freezer at - 18°C or below.
  • Canned food should be transferred to a non-metal container after opening and properly covered before it is stored in the refrigerator.
  • It is not necessary to put unopened sterilized food or unripe fruit in the refrigerator.
  • Allow leftovers to cool before refrigerating.
  • Food taken out of the refrigerator should be thoroughly cooked or reheated until the core temperature of the food reaches 75°C or above.
  • Food should not be stored in the refrigerator for a long period. In general, leftovers should not be stored in the refrigerator for more than three days
  • Non-perishable food, such as beverages, can be kept on the door shelves.
  • The refrigerator should be sufficiently ventilated; avoid overstocking the refrigerator to maintain even distribution of cold air inside.
  • Keep the door closed as often as possible to prevent the rise of temperature inside the refrigerator.


Longibility:

The longibility of spiral fin is 2 to 3 years. We only provide lifetime warranty of the L-fin coils manufactured by us.

Technical effort:

  • We make the refrigeration sytem by using both "L-fin" and "Spiral fin"
  • The refrigeration components are attached to the cabinet using screws and clips. The tubing is soldered together, and a protective coating is sprayed on the joints. The order of this assembly varies between manufacturers and models. The copper tubing from which the coils (condensers and evaporators) have separately been cut, bent, and soldered is then attached to the refrigerator as a unit.
  • The seal on the refrigerator door is created by means of magnet laden gaskets that are attached to the doors with screws. Handles and hinges are also screwed onto the door before its hinges are screwed onto the cabinet. Some adjustment is allowed for proper operation of the door.


Market abilities:

In terms of freon, several intermediate steps have been taken to minimize CFC emission as researchers attempt to identify safe coolant alternatives. Refrigerator designs have been improved to reduce the amount of freon needed; leak detection systems have been installed; maintenance has been limited to trained, authorized personnel; and refrigerant is recovered and recycled whenever possible. Moreover, long-term replacements for freon are being explored. Thus far, the most promising among them is HCFC-22, which, although still a chlorofluorocarbon, contains an additional hydrogen atom that reduces the molecule's ozone-depletion capacity by 95 percent. While its cost (three to five times greater than that of freon) is problematic, HCFC-22 is presently undergoing tests to determine its toxicity.
