In the demanding world of domestic refrigeration, the choice of a compressor determines the longevity and efficiency of the appliance. Two of the most prominent contenders for the 14-foot Kiriazi and similar medium-sized refrigerators are the Huayi HYE55YL63 and the ZMC EGM60AF. Both are engineered for Low Back Pressure (LBP) applications using R134a gas, but they offer distinct technical nuances that every field technician and engineer should understand.
The Huayi HYE55YL63 is a compact powerhouse with a 5.5cc displacement, optimized for balanced energy consumption. In contrast, the ZMC EGM60AF is often viewed as a slightly more robust alternative, providing a higher cooling capacity and a larger oil reservoir, which can be advantageous in high-ambient temperature environments. Understanding the intersection of these two models is essential for achieving “first-time-right” repairs.
| Feature | Huayi HYE55YL63 | ZMC EGM60AF |
| Model | HYE55YL63 | EGM60AF |
| Utilisation (LBP) | LBP (Low Back Pressure) | LBP (Low Back Pressure) |
| Horsepower (HP) | 1/5 HP | 1/5 HP (High Efficiency) |
| Refrigerant Type | R134a | R134a |
| Cooling Capacity (-23.3°C) | 155 W (529 BTU/h) | 182 W (621 BTU/h) |
| Displacement | 5.5 cm³ | 6.0 cm³ |
| Oil Type and Quantity | POE / 200 cm³ | Ester / 270 cm³ |
| Motor Type | RSCR | RSIR / RSCR |
| Power Supply | 220-240V / 50Hz | 220-240V / 50Hz |
| LRA (Locked Rotor Amps) | 6.5 A | 11.72 A |
| Weight | 7.9 kg | 8.58 kg |
| Winding Material | Copper | Copper |
While both compressors are rated at 1/5 HP, the ZMC EGM60AF features a larger cylinder volume of 6.0cc compared to the 5.5cc of the Huayi model. This translates directly into a higher mass flow of refrigerant.
