Mbsmpro.com, White Point, WPMR91S, Refrigerator, 1/12 hp, R600a, 13g, 0.50 A, 220-240V 50Hz, LBP, Made in Turkey

The White Point WPMR91S represents the modern standard for compact, energy-efficient refrigeration. Manufactured in Turkey, this unit is specifically designed for domestic cooling applications, utilizing the thermodynamic advantages of R600a (Isobutane). Unlike older systems that used heavy refrigerant loads, this high-efficiency cycle operates with a precision charge of only 13 grams.

Thermodynamics and Efficiency

The WPMR91S is built around a Low Back Pressure (LBP) cycle. With a rated current of 0.50 Amperes, the electrical footprint is remarkably low. The integration of R600a allows the compressor to operate at lower pressures compared to R134a, which reduces mechanical wear on the piston and valves, extending the lifespan of the motor.

Engineering Comparison: R600a vs. R134a

Technical Parameter	WPMR91S (R600a)	Equivalent R134a Unit
Mass Charge	13g	~45g – 60g
Operating Pressure	Below Atmospheric (Vacuum)	Positive Pressure
COP (Efficiency)	Higher	Lower
Environmental Impact	GWP 3 (Eco-Friendly)	GWP 1430 (High Impact)

Professional Maintenance Notice

As an expert in the field, I must emphasize that when servicing the WPMR91S, the 13g charge is critical. Because the volume is so small, traditional manifold gauges can trap a significant percentage of the gas in the hoses.

• Scale Precision: Use a digital scale accurate to 1 gram.
• Vacuum: A deep vacuum is mandatory as R600a systems are highly sensitive to moisture and non-condensables.
• Safety: R600a is flammable. Ensure no open flames or sparks are present during the charging process.

Benefits for the End User

The primary benefit of this specific engineering setup is the Isolation Degree IPX4, which provides protection against moisture ingress, making it ideal for various climates. The use of a PTC relay instead of a mechanical start relay further reduces the “click” noise during startup, providing a quieter user experience.

Excerpt: The White Point WPMR91S is a high-efficiency 91-liter refrigerator utilizing a specialized 13-gram R600a refrigerant charge. Operating at 0.50A, this Turkish-made unit is designed for optimal LBP performance. This guide provides comprehensive technical specifications, compressor cross-references, and engineering insights for professional technicians and hobbyists looking for reliable maintenance data and replacement parts.

Based on the technical specifications of both compressors, it is not recommended to replace the burnt-out compressor (Jiaxipera N1113Y) with the second one (ACC HTK70AA).

Here is the technical comparison:

1. The Original Compressor (Jiaxipera N1113Y)

• Displacement: 8.9 cm³
• Cooling Capacity: Approximately 154 Watts
• Horsepower Equivalent: Roughly 1/6 HP
• Gas Type: R600a

2. The Replacement Compressor (ACC HTK70AA)

• Displacement: 6.64 cm³
• Cooling Capacity: Approximately 117 Watts
• Horsepower Equivalent: Roughly 1/8 HP
• Gas Type: R600a

---

Why this is a bad match:

While both compressors use the same refrigerant (R600a) and voltage (220-240V), the ACC HTK70AA is significantly weaker than the original Jiaxipera.

If you install it, the following problems will occur:

1. Poor Cooling: The fridge will take a very long time to get cold, and it may never reach the desired temperature, especially in hot weather.
2. Continuous Running: Because the compressor is undersized, it will stay “on” almost all the time to try to cool the unit.
3. Short Lifespan: Working continuously will cause the replacement compressor to overheat, leading to a very short life before it burns out as well.

Conclusion:

You should look for a replacement compressor that has a cooling capacity of around 150–160 Watts or a displacement of 8.9 cm³ (equivalent to 1/6 HP). Using the 1/8 HP compressor (the ACC model) will likely result in a failed repair.

Technical Article: The Engineering Reality of Compressor Sizing

In the field of refrigeration, a compressor is the heart of the system. For an expert technician, replacing a unit isn’t just about finding a motor that fits the mounting bracket; it is a calculation of thermal dynamics. A common question arises when a Jiaxipera N1113Y fails: Can an ACC HTK70AA serve as a reliable substitute?

The short answer is no. To understand why, we must look at the displacement and the cooling capacity (Watts). The Jiaxipera N1113Y is a powerhouse in its class, designed for medium-to-large domestic refrigerators. It features a displacement of 8.9 cm³ and delivers approximately 154 Watts of cooling at Low Back Pressure (LBP) conditions.

In contrast, the ACC HTK70AA is a smaller unit. With a displacement of only 6.64 cm³, it produces around 117 Watts. When an undersized compressor like the HTK70AA is installed in a system designed for a 154W load, the compressor will run continuously, overheat, and eventually experience mechanical failure or winding burnout.

Comparative Analysis Table

Feature	Jiaxipera N1113Y	ACC HTK70AA	Impact of Difference
Displacement	8.9 cm³	6.64 cm³	Lower volume per stroke
Cooling Capacity	154 W (~1/6 HP)	117 W (~1/8 HP)	24% loss in cooling power
Current (LRA)	~7.5 A	~6.1 A	Different torque characteristics
Efficiency (COP)	High Efficiency	Standard Efficiency	Increased energy consumption

Why “Close Enough” Isn’t Good Enough

When you install a 1/8 HP compressor where a 1/6 HP unit is required, the internal pressures of the refrigeration cycle change. The suction pressure will remain higher than intended because the smaller piston cannot evacuate the evaporator quickly enough. This leads to poor frost patterns and higher cabinet temperatures, especially during high ambient summer conditions.

Copper Pipe Flaring: Common Mistakes and How to Avoid Them in HVAC and Plumbing Installations

Improper flaring can lead to refrigerant leaks, system inefficiency, and costly repairs. This guide outlines the most frequent errors and how to engineer flawless connections.

Mbsmpro.com, Copper Pipe, Flaring, HVAC, Plumbing, R600a, Mini-Split, Leak Prevention, Soft Copper, Flaring Block, 1/4″, 3/8″, 1/2″, 5/8″, Refrigerant Line

Understanding Copper Pipe Flaring

Flaring is the process of shaping the end of a copper pipe into a conical form to create a tight seal with flare fittings. It’s widely used in HVAC systems, refrigeration lines, and plumbing to ensure leak-proof connections—especially when working with R600a, R134a, or R410A refrigerants.

Common Mistakes in Copper Pipe Flaring

Mistake	Impact	Correction
Uneven flare	Causes leaks	Use calibrated flaring tools
Over-tightening	Damages flare face	Torque to spec using flare nut wrench
Under-tightening	Loose connection	Confirm seal with leak detector
Dirty pipe ends	Poor seal	Clean and deburr before flaring
Wrong pipe size	Misfit with flare nut	Match pipe with fitting size (e.g., 1/4″, 3/8″)
No lubrication	Cracked flare	Use flare oil or refrigerant-safe lubricant
Using hard copper	Cracks during flaring	Use soft copper tubing only

Comparison: Flaring vs. Brazing

Method	Seal Quality	Ease of Repair	Tool Cost	Leak Risk
Flaring	High (if done right)	Easy	Low	Medium
Brazing	Very High	Difficult	High	Low

Flaring is preferred for mini-split systems and field repairs, while brazing is ideal for permanent joints.

Engineering Tips for Perfect Flares

• Use a flaring block or hydraulic flaring tool for consistent results.
• Heat the pipe slightly if working in cold environments to prevent cracking.
• Inspect flare face for concentric rings and smooth finish.
• Always pressure test after installation to verify seal integrity.

Benefits of Proper Flaring

• Leak-free connections reduce refrigerant loss and environmental impact.
• Improved system efficiency due to stable pressure.
• Longer equipment life with reduced wear on compressors and valves.

Guide to Common Refrigerants: Standing, Suction and Discharge Pressures for Modern HVAC Systems

Refrigeration technicians today work with a mix of legacy and new-generation refrigerants, each with its own safe pressure range and boiling temperature. Understanding these values is essential for accurate diagnostics, safe charging and long compressor life in air‑conditioning and commercial refrigeration.​

---

Key role of pressure charts

Pressure–temperature charts and standing/suction/discharge tables give technicians a fast reference for what a system “should” be doing at a given ambient or evaporating temperature.​
Using wrong reference values can lead to over‑charging, overheating, liquid slugging or misdiagnosis of a healthy system as faulty.​

---

Overview of common refrigerants

The image groups the most used refrigerants in residential and light commercial systems: R22, R134a, R600a, R32, R290, R407C, R404A, R410A and R417 (R417A).​
Each gas has a typical standing pressure (static pressure at rest), an evaporating suction pressure, a condensing discharge pressure and a characteristic boiling point at atmospheric pressure.​

Safety, cylinder colours and replacements

Many countries use conventional cylinder colour codes to identify refrigerants quickly on site, although some regions are migrating to neutral colours with clear labelling.​
Hydrocarbons such as R290 and R600a are flammable, so working pressures must always be combined with strict leak‑prevention, ventilation and ignition‑control procedures.​

When phasing out ozone‑depleting R22, blends like R407C or R417A are often used in retrofit projects, while new high‑efficiency equipment typically relies on R410A or R32 with different design pressures.​
Comparing the standing and operating pressures during commissioning helps ensure that a replacement refrigerant is compatible with existing components such as compressors, valves and heat‑exchangers.​

Practical use for technicians and trainers

• Technicians can laminate similar tables and keep them in the toolbox or on the workshop wall as a quick‑reference during charging and troubleshooting.​
• Training centres and HVAC content creators like Mbsmgroup and Mbsm.pro can turn these values into interactive quizzes, infographics or mobile‑friendly charts for students and new technicians.​​
