Compared with the use of electric heaters or fuel boilers to heat hot water and indoor heating, Copeland Scroll ZW series compressors for heat pumps have a higher energy efficiency ratio and are widely used in domestic hot water, home heating and industrial applications such as drying and plating, as well as drying, plating and other industrial applications, which have been widely recognised for their reliability and high efficiency.
Case Details
Copeland Scroll ZW series compressor features are as follows:
1. High-efficiency performance: Adopting EVI Scroll Strong Heat Technology and Digital Scroll Technology, it is able to work stably at extreme low temperatures (-30℃), improving the heating efficiency and energy efficiency ratio.
2. Capacity Adjustment: Supports 0%-100% stepless capacity adjustment to ensure precise temperature control.
3. Environmentally friendly features: ZW series compressors can use environmentally friendly refrigerants to reduce the damage to the ozone layer and lower CO2 emissions.
4. Durability: Dual-flex design ensures a tight seal between the scroll discs, allowing the discs to separate radially and axially, allowing debris or liquids to pass through the discs without damage to the compressor.
5. Low noise and vibration: Designed with a smooth sound spectrum and soft sound quality, the compression chamber is always symmetrically distributed, very low unbalanced stress, high precision manufacturing process, no vibration absorbing devices required.
6. Start-up technology: unloaded start-up technology, compression parts separate from each other after shutdown, full pressure balance inside the compressor, no additional start-up devices.
7. Bearing technology: high-efficiency ‘Teflon’ bearings, upper main bearings and drive bearings.
8. Parallel compressor packages: can be assembled into parallel compressor packages for greater heat production. Equipped with oil and refrigerant balancing port to improve the stability and reliability of the system.
9. Structural design: Unique scroll disc design improves compression ratio and differential pressure, enabling efficient operation in a wider range of operating conditions. Equipped with high-efficiency and high-power motor, suitable for extreme application conditions.
10. Technical parameters and models: a variety of models and configurations, each corresponding to a different displacement and features to meet the needs of different applications.
The above features make Copeland Scroll ZW series compressors ideal for use in heat pump systems, especially for domestic hot water, home heating, drying, electroplating and other industrial applications.
Example1ZWD81KA-TFD-532:Voltage: 3φ/380-420V/50Hz;460V/60Hz
Refrigerant: R134a
Heat production capacity: 16.1kW
The ZWD81KA-TFD-532 compressor uses axial flexibility to regulate capacity by forcing the scroll discs to separate, stopping refrigerant compression without stopping the compressor. When the scroll disc is in the unloading state, the compressor capacity output is 0; when the scroll disc is in the loadeding state, the compressor capacity output is 100%. In a certain cycle time (e.g. 15 seconds), the output capacity is the sum of the average of the loading and unloading state times. By changing the loading state time and unloading state time, the compressor capacity can be infinitely adjusted from 10% to 100% to achieve the effect of precise temperature control.

ZW150KBE-TFP-522:
Voltage: 3φ/380V/50Hz
Refrigerant: R134a
Heat production capacity: 31.5kW
It incorporates Copeland's TMEVI Scroll Thermal Technology and a variety of new design features, which reliably extends the heating range of heat pumps and water heaters to ambient temperatures of -30°C and increases heating capacity by approximately 40 per cent, with a 22 per cent increase in energy efficiency.
