2. Technical Specifications of

Compressor Specifications:

1. Model Name: LG LBP MB88NA
   • This is the specific model number of the compressor manufactured by LG.
2. Power Consumption: 151 W
   • The compressor consumes 151 watts of electrical power during operation. This indicates the energy efficiency of the unit.
3. Horsepower (HP): 1/5 HP
   • The compressor has a motor rated at 1/5 horsepower , which is equivalent to 0.2 HP . This is a relatively small compressor, typically used in compact refrigeration systems or appliances like mini-fridges or beverage coolers.
4. Refrigerant Type: R600a
   • R600a (isobutane) is an eco-friendly refrigerant with low global warming potential (GWP). It is commonly used in domestic refrigerators and freezers due to its energy efficiency and minimal environmental impact. However, it is flammable, so proper handling is required.
5. Electrical Configuration: 1 Phase, 220V, 50Hz
   • The compressor operates on a single-phase power supply with a voltage of 220 volts and a frequency of 50 hertz . This configuration is typical for residential applications in regions like Europe, Asia, and parts of Africa.

Applications:

Given the specifications, this compressor is likely designed for use in low-back pressure (LBP) systems. LBP compressors are typically used in:

• Household refrigerators
• Freezers
• Beverage coolers

The P14TY is a refrigerant compressor model listed in the provided datasheet, designed for use in refrigeration or air conditioning systems. Below is a summarized technical breakdown of its key specifications:

P14TY Compressor Specifications

Key Observations

1. Refrigerant (R12):
   • The P14TY is designed for R12, an obsolete CFC refrigerant banned under the Montreal Protocol due to ozone depletion. Modern alternatives (e.g., R134a, R404A) require retrofitting or replacement.
2. Applications:
   • Likely used in medium-temperature refrigeration (e.g., commercial refrigerators, chillers) given its capacity and COP at -25°C evaporating temperature.
3. Efficiency (COP 1.73):
   • Lower COP compared to modern compressors, indicating higher energy consumption.
4. Replacement Considerations:
   • If retrofitting for alternative refrigerants, ensure compatibility with oil type (e.g., POE for HFCs) and system components.
   • Verify electrical specs (voltage, starting torque) for new installations.

Testing Conditions (CECOMAF/ASHRAE)

• Evaporating Temp: -25°C (LBP testing for low-temperature applications).
• Condensing Temp: 55°C.
• Ambient Temp: 32°C.

Actionable Recommendations

• For Maintenance:
  • Check oil levels and contamination if still using R12.
  • Inspect capacitors/relays (common failure points in CSIR motors).
• For Replacement:
  • Consider modern equivalents (e.g., Panasonic/Copeland models for R404A/R134a).
  • Consult HVAC technician for system compatibility and retrofitting.

• Do not tamper with the pre-filled specialized oil in the compressor.
• Use appropriate tools and equipment to ensure safe handling of R600a.

4. Refrigerator Size Estimation

The cooling capacity of a compressor determines the refrigerator size it can support. For example:

• BTF60AA (1/7 HP):
  • Cooling Capacity: 105 W
  • Approximate Refrigerator Size: 157.5 – 210 liters
    • Calculation: $105\text{W}\times 1.5\text{to}2=157.5\text{to}210\text{liters}$

6. General Requirements for Installation and Operation

• Store compressors in a dry, well-ventilated area.
• Avoid tilting or inverting during transportation.
• Install within 10 minutes after removing protective plugs.
• Ensure reliable grounding during operation.
• Avoid high-voltage or vacuum conditions during startup.

To determine the refrigerator size (in liters) that a 1/7 HP compressor can cool, we need to refer to the performance data of the compressors listed in the provided files. Specifically, the BTF60AA compressor (1/7 HP) is a good reference point for this calculation.

Key Specifications for BTF60AA (1/7 HP):

• Cooling Capacity: 105 W
• Refrigerant: R600a
• Voltage: 220-240V / 50Hz

The cooling capacity of a compressor directly correlates with the volume of the refrigerator it can cool. Typically:

• 1 W of cooling capacity can cool approximately 1.5 to 2 liters of refrigerator volume.

Calculation:

For the BTF60AA compressor with a cooling capacity of 105 W , the approximate refrigerator volume it can cool is:

$$\text{Refrigerator Volume}=\text{Cooling Capacity (W)}\times \text{Factor (1.5 to 2)}$$$$\text{Refrigerator Volume}=105\text{W}\times 1.5\text{to}2$$$$\text{Refrigerator Volume}=157.5\text{to}210\text{liters}$$

Table for 1/7 HP Compressor:

Below is a table summarizing the approximate refrigerator size (in liters) based on the cooling capacity of a 1/7 HP compressor:

Compressor Model	Power (HP)	Cooling Capacity (W)	Approximate Refrigerator Size (Liters)
