一、Overview

Model Groups

二、Group A — 9 HP Large Heat Pump Compressors

• Feature: Adopts EVI (Enhanced Vapor Injection) technology, increasing refrigerant flow through a second suction port (vapor injection port). Axial compliant design allows scrolls to separate slightly during operation, improving compression ratio and pressure differential tolerance.

  
  

• Advantage: COP up to 4.16—every 1 kW of electricity consumed produces 4.16 kW of heat. Single-unit heating capacity of 35.6–35.9 kW, the highest in the ZW series. Heating range extended to -35°C. Capable of producing 85°C high-temperature hot water. Supports parallel compressor units with oil and refrigerant balance ports.

  
  

• Benefit: Reduces system complexity and installation costs for large projects. Suitable for coal-to-electricity retrofit projects—stable heating even in extreme cold. 85°C high-temperature hot water directly meets industrial drying and electroplating needs.

  
  

三、Group B — 5 HP Medium Heat Pump Compressors

• Feature: EVI technology and axial compliant scroll design enable operation under wider conditions than standard heat pump A/C compressors—especially stable performance in harsh conditions of low ambient temperature and high water outlet temperature.

  
  

• Advantage: 19.6–20.3 kW heating capacity with only 4.9–5.0 kW input power. Compact 30 kg design, over 50% weight reduction compared to semi-hermetic compressors of the same heating capacity. Zero ODP refrigerant, effectively reducing CO₂ emissions.

  
  

• Benefit: 5 HP is the most mainstream power specification for heat pump hot water and heating. Suitable for 150–200 m² residential heating. Provides stable hot water for hotels, restaurants, and factories.

  
  

四、Group C — 2.5–3 HP Compact Heat Pump Compressors

• Feature: Dual power versions—single-phase 220V (PFS suffix) and 3-phase 380V (TFP suffix). Single-phase versions eliminate the need for 3-phase power upgrades, significantly reducing grid modification costs for rural coal-to-electricity projects.

  
  

• Advantage: 22 kg net weight, among the lightest models in the ZW series. 10.1–11.8 kW heating capacity meets heating and hot water needs for 100–150 m² residences. EVI technology ensures stable heating at -30°C.

  
  

• Benefit: Rural coal-to-electricity projects using single-phase 220V reduce installation costs. Compact design for residential hot water systems, easy integration with storage tanks. Small commercial drying with stable heating ensures drying efficiency.

  
  

五、ZW Series Core Advantages

• EVI Scroll Heating Technology: Increases refrigerant flow through vapor injection port, achieving two-stage compression. Heating capacity increased by ~40%, energy efficiency improved by 22%, heating range extended to -35°C.

  
  

• High-Temperature Hot Water Capability: Capable of producing hot water up to 85°C, meeting both industrial production and domestic hot water needs.

  
  

• Flexible Parallel Expansion: Compressors can be assembled into parallel units with oil and refrigerant balance ports to meet higher heating demands.

  
  

• Zero ODP Environmental Protection: Compatible with zero-ODP refrigerants, effectively reducing CO₂ emissions and meeting environmental regulations.

  
  

• Dual Refrigerant Options: KSE series for R407C eco-friendly refrigerant, KS series for R22 traditional refrigerant, allowing flexible selection based on system requirements.
