III. Detailed Explanation

Feature – Technical Characteristics

The Small-Capacity Group adopts Copeland's axial and radial compliant scroll technology, allowing the scrolls to separate slightly during operation, enabling liquid refrigerant and impurities to pass through without damaging the compressor.
The entire series uses R410A environmentally friendly refrigerant with zero ODP (Ozone Depletion Potential).
ZP34K5E and ZP36K5E are equipped with built-in motor protectors to ensure motor safety under abnormal operating conditions.

Advantage – Technical Advantages

This group's core advantage is its compact lightweight design. ZP34K5E has a net weight of only 28.9 kg and ZP36K5E 29.2 kg, achieving over 50% weight reduction compared to semi-hermetic compressors of the same cooling capacity.
COP reaches 2.90–2.93, EER reaches 9.9–10.0 Btu/Wh, and energy efficiency outperforms traditional reciprocating compressors.
Noise level is controlled at 68 dBA, suitable for residential and light commercial scenarios with strict acoustic requirements.

Benefit – User Benefits

For applications such as residential central air conditioning, small commercial split systems, and rooftop units, this group reduces equipment integration and on-site installation difficulty with its lightweight design and flexible power compatibility.
For equipment manufacturers, the 16 capacity grades from ZP20K5E to ZP54K5E provide precise cooling capacity matching, avoiding selection waste from over-sizing.
For end-users, the high energy efficiency ratio of R410A systems significantly reduces annual operating electricity costs.

IV. Application Quick Selection Guide

Application Scenario	Recommended Model	HP	Key Advantage
Residential central A/C (small units)	ZP20K5E – ZP25K5E	1.9–2.1	Compact lightweight, low noise
Residential central A/C (medium/large units)	ZP28K5E – ZP36K5E	2.4–3.0	EER 10.0, high energy efficiency
Small commercial split systems	ZP38K5E – ZP44K5E	3.2–3.7	COP 2.90+, economical operation
Rooftop units / Unitary systems	ZP49K5E – ZP54K5E	4.1–4.5	Large cooling capacity, ideal for commercial use
