  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.

- 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 

- 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 maximum

  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

  - Supplier

     Assembling the mortuary refrigerator Trial run

  - User
