The Engineering Standard: Technical Analysis of the Jiaxipera TT1113GY Compressor
In the modern refrigeration landscape, precision engineering and environmental sustainability are no longer optional—they are foundational. The Jiaxipera TT1113GY stands at the forefront of this evolution, serving as a high-performance <u>Low Back Pressure (LBP)</u> compressor optimized for the eco-friendly R600a refrigerant. Designed for residential refrigerators and high-efficiency chest freezers, this unit exemplifies the shift toward high volumetric efficiency and low acoustic impact.
Technical Specifications and Thermodynamic Characteristics
The TT1113GY is built on a robust platform that balances power density with thermal stability. Below are the definitive parameters for technicians and refrigeration engineers:
| Feature | Detailed Specification |
| Manufacturer | Jiaxipera Compressor Co., Ltd |
| Model | TT1113GY |
| Horsepower (HP) | 1/5 HP |
| Refrigerant Type | R600a (Isobutane) |
| Cooling Capacity (-23.3°C ASHRAE) | 183 Watts (624 BTU/h) |
| Displacement | 11.3 cm³ |
| Power Supply | 220-240V ~ 50Hz (Single Phase) |
| Motor Type | RSCR / RSIR (Dependent on Start Device) |
| Cooling Type | Static Cooling (S) |

| Oil Charge | 180 ml (Mineral / Alkylbenzene) |
Comparative Analysis: Displacement vs. Cooling Efficiency
When evaluating the <u>TT1113GY</u> against legacy R134a systems, the difference in displacement volume is striking. R600a compressors require larger cylinders to achieve the same cooling capacity due to the lower gas density of isobutane.
- Jiaxipera TT1113GY (R600a): 11.3 cm³ displacement produces 183W.
- Standard R134a Equivalent: A similar capacity often requires only 7.0 – 8.5 cm³.
This increase in displacement is countered by a significantly higher COP (Coefficient of Performance). While older R134a models might operate at a COP of 1.15 W/W, the Jiaxipera TT1113GY typically achieves values between 1.35 and 1.50 W/W, drastically reducing electricity consumption in domestic applications.
Electrical Schema and Connection Protocols
For professionals in the field, understanding the electrical architecture is vital for system safety. The unit employs a single-phase induction motor with a split-phase winding.
- Main Winding (M): Low resistance, carries the running load.
- Start Winding (S): Higher resistance, used during the initial acceleration.
- Safety Tip: The use of a PTC (Positive Temperature Coefficient) starter is standard. When upgrading to RSCR (Resistance Start Capacitor Run) mode, a run capacitor (usually 4µf – 5µf) must be integrated across the ‘S’ and ‘R’ terminals to further improve electrical efficiency and lower the running amperage.
Comparison with Competitive LBP Models
| Brand & Model | Gas | HP | Displacement | Output (Watts) |
| Jiaxipera TT1113GY | R600a | 1/5 | 11.3 cc | 183 W |
| Secop NLE11KK.4 | R600a | 1/4 | 11.1 cc | 191 W |
| Embraco EMX70CLC | R600a | 1/5+ | 11.1 cc | 182 W |
| Huayi HYB11.5 | R600a | 1/4 | 11.5 cc | 188 W |
Engineering Best Practices: Advice and Benefits
Operating with <u>R600a (Isobutane)</u> requires a heightened level of awareness due to its flammability (A3 safety classification).
- Vacuum Procedure: Always pull a vacuum down to 200 microns. Moisture in an R600a system with mineral oil can cause rapid mechanical acidification.
- Copper-Aluminum Joints: Ensure vibration dampeners are secure. The 11.3cc stroke creates significant torque oscillation; poorly brazed joints will leak over time.
- Filtration: Utilize a filter drier specifically labeled for XH-9 molecular sieves to maintain refrigerant purity.
- No Flame Braze: In field repair environments, ultrasonic welding or Lokring technology is preferred for sealing R600a process tubes to eliminate the risk of explosion.
Benefits of the Jiaxipera TT1113GY:
- Ultra-Quiet Performance: Specially damped valve plates reduce “click” noises during startup.
- Global Standard Compliance: Fully meets ROHS and CE regulations for environmental safety.
- Energy Efficiency: Direct contribution to reaching A++ or A+++ energy ratings in residential refrigerators.
