Product Description

1. Super High Energy Efficiency Ratio (+12%)

This compressor adopts a scroll-type structure, achieving a volumetric efficiency of up to 98%. Its energy efficiency ratio is significantly higher than that of traditional piston compressors, saving substantial electrical power consumption under identical operating conditions. 1 4

2. Outstanding Reliability

• Few moving parts, with flexible axial and radial designs providing unprecedented tolerance for liquid slugging and impurity ingestion.

• Built-in motor protection device effectively safeguards the motor from damage caused by high temperature and overcurrent.

• The dual-flexible design allows the scroll wraps to separate radially and axially, enabling debris or liquid to pass through without damaging the compressor. 2 3

3. Low Noise/Low Discharge Pulsation

The noise level is more than 5 dB lower than that of piston compressors. The compression chambers are always symmetrically distributed, with minimal torque variation, ensuring smooth operation and extremely low vibration. 1 3

Other Significant Advantages

• Simplified System Design: The unique unloaded start design eliminates the need for starting capacitors/relays for single-phase compressors. In most applications, crankcase heaters and suction accumulators are not required.

• Near 100% Volumetric Efficiency: Delivers exceptional heating capacity.

• Compact Structure: Small footprint, lightweight, easy to install and maintain. 2 10

These advantages make the ZR34K3-TFD-522 an ideal choice for commercial air-conditioning refrigeration equipment, central air-conditioning systems, and other related fields.

Applicable scenarios

This Copeland ZR34K3-TFD-522 compressor, with its 2.8 HP power rating and 8200W cooling capacity, is highly suitable for various commercial air-conditioning and refrigeration equipment, especially in applications that prioritize high energy efficiency and stable operation.

Selection and Usage Considerations

To ensure the compressor delivers optimal performance within the system, the following key points should be taken into account:

• System Compatibility: During the design or modification of the system, ensure that the compressor's operating conditions (such as maximum refrigerant pipe length, equipment elevation difference, etc.) are compatible with the overall system requirements. 12 14

• Refrigerant Selection: This compressor is designed to use R22 refrigerant. 2 5 It should be noted that R22 is an HCFC-type substance, and its use in new equipment may be restricted in some regions. Environmental regulations should be considered when planning new projects.

• Professional Installation and Maintenance: The installation, commissioning, and subsequent maintenance of the compressor must be carried out by qualified professionals to ensure stable system operation and extend the equipment's service life.
