   2-1 Panel part

1) Non-corrosive stainless steel (internal: 2B 0.6t, external: 2B H/L 0.6t) is used and each of the

    component parts must be manufactured according to the intended use, and sufficient mechanical

    strength and feature made to apply

2) It should be installed easily both indoors and outdoors, and should be manufactured for the

    maintenance in convenience.

3) It should be used the panel with over 50 mm of thickness of urethane foam which can minimize

    heat transfer

4) It should be foamed not to get a foreign substance stuck in the corner between the lower panel

    and upper panel (refer to the attached figure)

    This makes it convenient assembling or disassembling for the side panel, the upper and lower panels

    so as to maintain airtightness.

5) It should be attached an overheat prevention heater at the door frame of the refrigerator to prevent

    overheating and heat rays. It should be prevented from the dew condensation through no temperature

    difference with the outside.

6) Door locks and fixing hinges must be manufactured to withstand the load. Must be stainless or chrome

    plated.

7) Handle and hinge fixing bracket (3.2T burring tap) is used to prevent corrosion. It must be galvanized.

8) It should be attached the caster (swivel and fixing) and high poles at the lower side of refrigerator so as

    to install the refrigerator and move in convenience. 

9) As for the panel dedicated to the infected, it is sealed between the upper and the lower compartments, 

    and operates independently.

  the repairing in convenience.  

2) Condenser

- The thermocouple must be a seamless phosphorus deoxidized copper tube (KSD 5301) or equivalent

  with a purity of 99% or higher, and there should be the uniformity of the copper tube and no harmful

  defects in use.

- As for the copper tube and the FIN, these are mechanically expanded and closely contacted so that they

  have sufficient  thermal contact surface.

- It uses the FIN which is 0.11T of Aluminum foil with a purity of 99.9% or more. 

  It should be coated with thermosetting resin on FIN in order to improve excellent corrosion resistance and

  thermal efficiency.

- It should be implemented for the pressure test at 37.5kg/cm2.G, and the airtight test at a pressure of

  25kg/cm2.G or above. There should be no abnormalities such as leakage and deformation.

3) Hermetic reciprocating compressor (Compressor)

- The compressor is an internationally verified hermetic compressor.

- Use alternative refrigerants R-134 and R-404 for refrigerant.

- When connecting the compressor with pipe, the welding area is 

  coated with an anticorrosion paint, and wiring use a contactor.

- To protect the winding of the compressor motor, it is used the Compressor

  coverload relay F.O.C.R or the overload protector MPDULE to prevent from the damage to the motor.

- When assembling the compressor with the base, vibration-proof rubber and vibration-proof spring are

  used to prevent      from the vibration.

- It is installed a CHARGE NIPPLE on the compressor for refrigerant supplement and air tightness test.

- Make sure to drive the compressor at about 70% of the maximum load.

4) Fan for condenser

- Make sure to use a fan with a low-noise propeller type, and it should be able to blow a sufficient air for

  condensation.

- It has sufficient strength for the required RPM, and performs static and dynamic balance tests for a quiet

  operation.

- The motor is insulation class F, and its structure and general characteristics are in accordance with KSC

  4201~4206 conformity.

- The drive method is a direct connection method.

5) Control box and operation panel

- Make it possible to display various operating conditions of the device. (run/stop, defrost timer switch,

  temperature controller, thermometer and various indicators)

- All parts should have no abnormality in the withstand voltage test.

 

6) Evaporator

- The thermocouple must be a seamless phosphorus deoxidized copper tube (KSD 5301) or equivalent

  with a purity of 99% or higher, and there should be the uniformity of the copper tube and no harmful

  defects in use.

- As for the copper tube and the FIN, these are mechanically expanded and closely contacted so that they

  have sufficient thermal contact surface.

- It uses the FIN which is 0.11T of Aluminum foil with a purity of 99.9% or higher. It should be coated with

  thermosetting resin on FIN in order to improve excellent corrosion resistance and thermal efficiency.

- It should be implemented for the pressure test at 22kg/cm2.G, and the airtight test at a pressure of

  15kg/cm2.G or above. There should be no abnormalities such as leakage and deformation.

7) Fan for Evaporator

  over 99% or equivalent one, and there should be uniformity of the copper tube and no harmful defects in

  use.

- Make sure to be minimized bends during piping work.

- After the piping is installed, perform a leak test with nitrogen gas to confirm no abnormality.
