The backbone of the P series features displacements ranging from 14 to 20 cm³, with power ratings covering 1 HP to 1.5 HP. These are the mainstay models for residential split air conditioners, cabinet air conditioners, and light commercial refrigeration equipment.
Features and Advantages
1. Clear Power Gradient for Precise Selection
The three models feature displacements increasing from 14 to 20 cm³, with cooling capacities ranging from 2220W to 3245W, forming a clear power gradient. This allows for precise matching based on room area and cooling load, avoiding energy waste or insufficient cooling caused by oversizing or undersizing.
2. Excellent Energy Efficiency Performance
Taking the 2P14S225ANJ as an example, it achieves a COP of up to 3.15 and an EER of 10.74. This energy efficiency level is among the best in its class, significantly reducing long-term operating electricity costs for residential air conditioning.
3. Outstanding Cooling Output Capacity
2P14S225ANJ: Cooling capacity 2220W (7575 BTU/h), input power 705W
2P17S225ANQ: Cooling capacity 2770W, input power 885W
2P20S225BNG: Cooling capacity 3245W, input power 1080W
The incrementally designed power ratings ensure comprehensive coverage from bedroom air conditioners to living room cabinet units.
4. Mature and Reliable R22 Platform
As a mature platform optimized for R22 refrigerant, this compressor series features a well-established technical system, abundant spare parts supply on the market, and lower maintenance costs. It continues to have extensive application demand in the existing stock air conditioning market.
5. Low-Noise Operation
The P series is renowned for high efficiency and low noise. Through optimized balanced design and precision machining, it operates smoothly and quietly, meeting the strict silence requirements of both residential and commercial environments.
Q1: How to select among the three P-series models?
A: The three models form a clear power gradient — the 2P14S225ANJ is 1 HP (2220W), the 2P17S225ANQ is 1+ HP (2770W), and the 2P20S225BNG is 1.5 HP (3245W). Selection guideline: choose the 2P14S for bedrooms of approximately 10–15 m², the 2P17S for master bedrooms or small living rooms of 15–22 m², and the 2P20S for living room cabinet units of 22–30 m². Undersizing will result in insufficient cooling and long-term high-load compressor operation; oversizing will cause frequent on/off cycling and energy waste.
Q2: How is the energy efficiency of the P series?
A: Taking the 2P14S225ANJ as an example, it achieves a COP of up to 3.15 and an EER of 10.74. This efficiency level is among the best in its class for 1 HP compressors, significantly reducing long-term operating electricity costs for residential air conditioning.
Q3: What should I do if the P series compressor is noisy during operation?
A: The P series is renowned for high efficiency and low noise, achieving smooth and quiet operation through optimized balanced design and precision machining. If noise increases, possible causes include: ① worn internal valve plates; ② contaminants in the system or insufficient refrigerating oil; ③ aged shock-absorbing pads on the mounting base. These should be checked one by one, and the compressor should be replaced if the problem is severe.
