Efficiency Metrics (COP) and Performance Data

Efficiency in a compressor is defined by the Coefficient of Performance (COP). For the TLES6FT.3, the relationship between evaporating temperature and energy consumption is crucial for maintaining energy ratings.

Evaporating Temp (°C)	Cooling Capacity (Watts)	Power Consumption (Watts)	COP (W/W)
-35	82	98	0.84
-30	112	114	0.98
-25	148	131	1.13
-23.3	156	138	1.14
-20	188	150	1.25
-15	240	170	1.41
-10	295	192	1.54

Note: The COP is calculated using the formula: $COP = \frac{Q_c}{P}$, where $Q_c$ is the cooling capacity and $P$ is the power input.

Application and Capability

This compressor is typically found in medium-sized domestic refrigerators.

• Cooling Capacity in Liters: It can efficiently handle cooling for units between 250 to 350 Liters.
• Cubic Feet: Approximately 8.8 to 12.3 cubic feet.

Replacement Guide

If you are in the field and cannot find the exact TLES6FT.3, here are the professional-grade alternatives.

5 Direct Replacements (Same Gas: R134a)

1. Embraco EMT55HLP: Very common, slightly higher efficiency.
2. Danfoss TL5G: The classic predecessor, extremely durable.
3. ACC / Cubigel GVY57AA: A direct fit for many European cabinets.
4. Jiaxipera ND1112Y: Often used in Bosch and Siemens units.
5. Tecumseh THG1358YKS: A robust alternative with similar mounting.

5 Indirect Replacements (Alternative Gas: R600a)

Caution: Gas conversion requires a complete system flush, different oil, and a specific R600a charging procedure.

1. Secop TLES6.5KK.3: The natural R600a evolution of this frame.
2. Embraco EMX55CLC: High efficiency R600a model.
3. Jiaxipera NT1113Y: Standard R600a replacement.
4. ACC HXK95AA: Known for very low noise levels.
5. Wanbao ATA72XL: Budget-friendly R600a alternative for 1/6 HP range.

Professional Advice & Field Tips

• Oil Management: The TLES6FT.3 uses POE oil. This oil is highly hygroscopic (absorbs moisture quickly). Never leave the compressor open to the atmosphere for more than 15 minutes.
• System Cleanliness: When replacing a burnt-out compressor, always replace the filter drier and perform a nitrogen purge to ensure no acid remains in the lines.
• Starting Device: This model supports both LST (Low Starting Torque) and HST (High Starting Torque). If you are working in an area with unstable voltage, adding a start capacitor (HST kit) can significantly extend the motor’s life.

Troubleshooting the TLES6FT.3

Problem	Potential Cause	Action
Compressor runs but no cold	Gas leak or partial blockage	Check high-side pressure and capillary.
Clicking sound (Thermal Protector)	Faulty relay or seized piston	Check LRA and relay resistance.
High vibration	Worn internal springs	Ensure the external rubber grommets are intact.

The Technician’s Guide: R134a vs. R600a Compressor Conversion

In the evolving world of refrigeration repair, the transition from HFCs (R134a) to Hydrocarbons (R600a) is no longer a choice—it is the standard. For the artisan bricoleur, understanding the relationship between these two refrigerants is critical. You cannot simply swap one for the other without understanding the physics of displacement and pressure.

This guide breaks down exactly what happens when you compare an R134a system to an R600a system, and how to correctly calculate the replacement if you are retrofitting a cabinet (changing the compressor and gas).

The Golden Rule: Displacement is King

The biggest mistake technicians make is matching “Horsepower to Horsepower” (e.g., swapping a 1/5 HP R134a with a 1/5 HP R600a). Do not do this.

R600a gas is much less dense than R134a. To pump the same amount of heat, the R600a compressor must have a larger cylinder volume (displacement).

• R134a Displacement Factor: 1.0
• R600a Displacement Factor: ~1.7 to 2.0

If you remove an R134a compressor with a 5.0 cc displacement and replace it with a 5.0 cc R600a compressor, the fridge will never get cold. You need an R600a compressor with approximately 8.5 cc to 10 cc to do the same work.

Technical Comparison: R134a vs R600a

Here is the data you need to understand the behavior of these gases inside your pipes.

Feature	R134a (Tetrafluoroethane)	R600a (Isobutane)	The Difference
Operating Pressure (Low Side)	0 to 2 PSI (Positive pressure)	-5 to -10 inHg (Vacuum)	R600a often runs in a vacuum. Leaks suck air in.
Displacement Required	Low (Dense gas)	High (Light gas)	R600a compressor needs ~70-80% bigger cylinder.
Charge Amount	100% (Baseline)	~45% of R134a mass	If R134a took 100g, R600a takes only ~45g.
Oil Compatibility	POE (Polyolester)	Mineral or Alkylbenzene	R600a is compatible with mineral oil (cheaper/less hydroscopic).
GWP (Global Warming Potential)	1430 (High)	3 (Very Low)	R600a is eco-friendly.
Flammability	A1 (Non-Flammable)	A3 (Highly Flammable)	Requires spark-proof tools and care.

Retrofit Table: Equivalent Displacement (Estimated)

Use this table when you are forced to replace a dead R134a compressor with a new R600a model on an existing fridge.

Original R134a Compressor	Approx. Displacement	Target R600a Compressor	Approx. Displacement
1/6 HP	4.0 cc	1/5 HP	~7.0 – 8.0 cc
1/5 HP	5.5 cc	1/4 HP	~9.0 – 10.5 cc
1/4 HP	7.5 cc	1/3 HP	~13.0 – 14.0 cc
1/3 HP	9.0 cc	3/8 HP	~16.0 cc

Note: These are estimations. Always check the Cooling Capacity (Watts) at -23.3°C (LBP) in the datasheet. The Watts must match!

Exploitation: The Capillary Tube & Oil Dilemma

When converting a system designed for R134a to use an R600a compressor, you face two hurdles:

1. Capillary Tube: R600a has a higher latent heat of vaporization. Ideally, it requires a slightly different restriction than R134a. However, in practice (for repair jobs), the original R134a capillary tube often works “acceptably” because the lower mass flow of R600a balances out with its higher specific volume. Do not shorten the capillary unless you have high superheat issues.
2. Oil Mixing: R134a systems contain POE oil stuck in the evaporator. R600a compressors come with Mineral oil. While R600a can tolerate some POE, it is best to flush the system with nitrogen and a flushing agent to remove as much old POE oil as possible before brazing the new compressor.

---

Safety First: Working with Isobutane

• No Brazing on Charged Systems: Never use a torch if there is any chance of gas in the system. Use tube cutters.
• Ventilation: R600a is heavier than air. It settles in low spots (floors, inspection pits). Ensure good airflow.
• Spark-Free: When vacuuming, ensure your pump switch and relay are not sparking sources near the vents.
