Electrical and performance data

Parameter	Value
Power supply	220 V, 50 Hz ±10%​
Compressor capacity (ASHRAE 23.3 °C)	156 W tropical hermetic compressor​
Approx. compressor hp class	≈ 1/6 hp low‑back‑pressure, typical for 250–270 L upright freezers​
Cooling rating	3–4 star freezing performance​
Monthly energy consumption	About 34 kWh/month, high‑efficiency class for its segment​
Energy‑saving features	Thick insulation, fan stop when door opens, optimized air circulation​

The 156 W ASHRAE rating places the compressor firmly in the 1/6 hp category, widely used for domestic vertical freezers because it balances pull‑down speed with low running consumption.​

Refrigeration circuit: refrigerant, capillary and oil

Official retail pages specify cabinet and compressor wattage but not full circuit details; the following values combine what is published for KH256VF with standard practice for similar Kiriazi no‑frost systems.​

Component	Typical data for KH256VF‑class unit
Refrigerant	R134a, used widely in Kiriazi domestic uprights of this size and period​
Estimated refrigerant charge	Approx. 120–150 g R134a (230 L Kiriazi uprights use ≈120 g; 270 L models usually fall slightly higher)​
Expansion device	Capillary tube feeding a forced‑air evaporator (no‑frost)​
Practical capillary range (service reference)	Internal diameter about 0.7–0.8 mm with 2.5–3.0 m length for 1/6 hp R134a low‑temperature application; exact factory size is not published and should be copied from the original tube when available.​​
Compressor type	Tropical hermetic LBP compressor, designed for high ambient temperatures​
Recommended oil type	POE (polyolester) oil for R134a domestic compressors, viscosity ISO 22–32​
Typical oil quantity	Around 200–300 ml for 1/6 hp hermetic can, exact value depends on compressor model plate​​

Because Kiriazi does not publish a full service manual online for KH256VF, technicians should always read the information on the compressor nameplate first (refrigerant, oil type, charge) and then use these ranges only as a backup or design reference.​

Practical service notes for technicians

• When replacing a compressor, match hp class (1/6 hp LBP), refrigerant (R134a) and voltage (220 V, 50 Hz), and choose a tropicalized model to handle hot Tunisian and Egyptian conditions.​
• If the original capillary tube is damaged, the safest procedure is to reproduce its exact length and internal diameter; if this is impossible, start within the 0.7–0.8 mm × 2.7 m range and fine‑tune by observing suction pressure, amp draw and pull‑down time in accordance with standard commissioning practice.​​
• Always evacuate to deep vacuum and weigh in the charge whenever the system is opened, especially with POE oil, which is highly hygroscopic and sensitive to moisture contamination.​

This table‑driven overview gives a field‑ready technical picture of the Kiriazi 6‑drawer no‑frost upright freezer, allowing you to plan repairs, retrofits or comparative evaluations with similar vertical deep‑freezer models.​
