LG Unitary Duty Rotary Compressor

The Unitary Duty Rotary Compressor is custom-designed for split- and packaged-system unitary HVAC applications such as single-family homes, apartments and multi-family residential units. The compressor, designed to produce the same results in capacity and efficiency as today’s scroll compressors, features two patented enhancements that contribute to its enhanced performance and improved durability: the new restarting solenoid valve and new discharge check valve.

The unitary duty rotary compressor was developed to start under a system load without the aid of harsh electrical start components.

Under certain conditions, these electrical devices may damage the compressor and affect the unit’s overall reliability. Instead, LG’s design team engineered a unique approach that relieves any load that may exist while the compressor is beginning to run. And while rotary compressors are commonly used in smaller settings, such as window units, the unitary duty rotary compressor is optimized for unitary applications. Its enhanced overload protector and reinforced mechanical parts serve applications requiring 1.5- to 2.5- ton capacity targeted at the 14 SEER level.

Its patented restarting solenoid valve mechanically equalizes pressure between the compressor shell and the low side of the system, creating a start-up process that is much smoother and less taxing on the components. The solenoid valve opens when power is interrupted to the compressor and closes when the compressor is energized.

LG’s patented discharge check valve, located in the discharge tube, increases system efficiency by managing refrigerant in the high side of the system during off cycles. Designed for the rigors of unitary operation, this check valve maintains pressure on the expansion device to preserve the lingering refrigeration effect when the compressor stops. This function is critical to achieving ever-increasing efficiency goals in the U.S. residential HVAC market.
