I. Core Configuration & Technical Features

1. Core Component Configuration

· Compressor:Utilizes a high-efficiency EVI (Enhanced Vapor Injection) scroll compressor, specifically optimized for low-temperature environments. Significantly enhances low-temperature heating capacity, substantially improves COP value, and broadens the operational range.

· Heat Exchanger: High-efficiency double-tube water-side heat exchanger, featuring a stainless-steel tube + inner grooved copper tube structure for enhanced heat transfer. Offers high pressure resistance (standard 1.6MPa), strong anti-fouling capability, and suitability for various water quality environments.

· Fan System: Large-diameter, low-speed axial fanwith aluminum alloy blades and an IP54-rated motor. Provides high airflow, low noise, stable operation, and adaptability to all-weather outdoor conditions.

· Refrigerant: Environmentally friendly R410a refrigerant.

2. Core Technical Features

· Ultra-Low Temperature Powerful Heating Technology:EVI technology ensures stable heating operation even at -25°C ambient temperature, reducing heating capacityAttenuation by over 30% compared to standard models.

· High-Efficiency Defrost Technology:Intelligent multi-parameter defrost control logic, combined with water temperature sensing from the double-tube heat exchanger, enables faster defrosting (approx. 3-5 minutes) with minimal water temperature fluctuation during the cycle.

· Adaptive Control:Flexible compressor modulation based on load demand and outdoor temperature, achieving 10%-100% stepless capacity control and superior part-load efficiency (IPLV).

· High-Reliability Design:The double-tube heat exchanger features an integral structure with no internal weld points, eliminating leakage risk. The compressor includes multiple protections (overload, phase loss, high/low pressure protection).
