2. Material and feature
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.
2-2 All-in-one refrigerator
1) Casing
- The material is used 1.2T of electric galvanized steel sheet (EGI) which has mechanical
feature, hardness, flexure, shape, dimension and thickness. These are in accordance with
KSD 3528
- The coating method is spray coating with a coating film thickness of 20μ ±1 using powder
coating. Dry for 20 minutes at a temperature of 130 ℃.
- The standard color is ivory.
- It should be easy assembling structure. In case of A/S, it should be manufactured easy
disassembling for 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 overload 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.
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
- 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.
8) Piping for Refrigerant
- For the thermocouple, use a non-seamless phosphorus deoxidized copper tube
(KSD 5301) with a purity 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.
9) Insulation for Refrigerant pipe
- Insulation of the pipe is made as the same size as the copper pipe.
- Make sure that there are no cracks in the seam of the insulation material.
- Insulation is carried out by wrapping with primary vinyl, insulating secondary, and
applying aximum pressure with the tape for cooler.
(Pipe is applied when installing outdoor unit)
10) Protection device
- Over current relay, Module, Fusible plug, Fuse
- Expansion valve
- Use a thermostatic expansion valve or capillary tube (2.2~2.6mm).
- When using a thermosensitive type, be careful about the sensing point.
- When using a capillary tube, wind it using a 50mm tube and install it.
- Insert the capillary tube sufficiently into the pipe to avoid clogging the welding area
before welding.
11) Defrost water evaporator
- Create a clean and hygienic environment by installing a forced or automatic evaporator
12) Scope of supply
