R410A Hermetic Scroll Compressors ESP-130-5
R410A Hermetic Scroll Compressors ESP-130-5
The ORBIT 8 series is a line of hermetic scroll compressors designed for R410A refrigerant, primarily used in air conditioning applications. These compressors are recognized for their high efficiency, smooth operation, and reliability. They are optimized for low energy consumption, particularly in part-load operations typical of seasonal air conditioning use. The design emphasizes reduced sound emissions and weight, offering compact dimensions compared to standard models.
Technical Features
The compressors provide high capacity and efficiency for both air conditioning and heat pump applications with R410A. They are designed to minimize annual operating costs and ensure low sound levels. The compressors feature a low oil carry-over rate and are suitable for parallel operation, capable of operating with a frequency inverter from 35 to 75 Hz.
Application Limits for R410A
The compressors are engineered to function within specific temperature ranges for evaporating and condensing temperatures, with defined limits for suction gas superheat.
Performance Data
Performance data is based on the European Standard EN 12900 and 50 Hz operation. The data excludes liquid subcooling, resulting in lower rated cooling capacity and efficiency compared to data that includes subcooling.
Energy Efficiency and Part Load Behavior
Two compressor families are developed: the "BITZER ORBIT" standard series for medium to high condensing temperatures, and the "BITZER ORBIT Boreal" series for low to medium condensing temperatures. These compressors achieve superior ESEER/IPLV values, up to 15% better than competitive models.
Scope of Standard Delivery
The standard delivery includes a built-in motor, electronic motor protection, various connection options, an oil sight glass, anti-vibration mountings, and a terminal box with IP54 protection. Optional accessories include an oil heater and temperature sensors.
Maximum Applied Pressure Limits
The compressors have a maximum applied pressure limit of 31 bar on the low-pressure side and 45 bar on the high-pressure side.
Performance Specifications
The document provides performance data for ORBIT 8 compressors operating at 50 Hz, based on a 10 K suction gas superheat without liquid subcooling. It includes detailed tables of cooling capacity (Q) and power consumption (P) across various saturated suction temperatures and condensing temperatures for different compressor models. The data is optimized for air-cooled systems and reversible chillers, with additional performance data available for 60 Hz operation via BITZER Software.
Technical Data
The compressors are charged with polyvinyl ether oil BVC32 and are available with direct brazing or Rotalock connections. The document specifies the displacement, oil charge, weight, and connection sizes for each compressor model. It also provides electrical data, including maximum operating amps, power consumption, and starting current. Conversion factors for different voltages are provided.
Dimensional Drawings
Dimensional drawings for ORBIT 8 compressors with both direct brazing and Rotalock connections are included. These drawings detail the connection positions for high and low-pressure lines, discharge and suction lines, and mounting positions for vibration dampers and fixing rails.
Connection Positions
The document outlines the connection positions for high pressure, discharge gas temperature sensors, low pressure, sight glass, and oil service connections. It also specifies the mounting positions for vibration dampers and fixing rails.
Additional Notes
The document notes that specifications are subject to change and provides contact information for BITZER Kühlmaschinenbau GmbH in Germany.
