  • Page 40: Operating Principles

    Operating Principles General The refrigeration cycle of RTXC-XE/XE-HSE is conceptually similar to that of other Trane air- cooled screw heat pumps, including single refrigerant circuit unit, dual refrigerant circuit unit, and assembly unit with master-slave control system. RTXC110XE/XE-HSE apply single refrigerant circuit with one compressor with economizer and one water loop.

  • Page 41: Oil Filter

    Economizers can be used with the compressor to increase cycle capacity and in some cases improve cycle efficiency, depending on the port machined into the rotor housing for economizer gas injection. The economizer should only be modulated once the compressor is running at 100% load and closed before the compressor shut down.

  • Page 42: Fan

    In cooling condition, all fans operate in high speed when ambient temperature is high, automatically adjust fan stage for AC fans or fan speed for EC fans when ambient temperature decreased. In heating condition, all fans run in high speed except warmup and defrost. The fans are propeller-type and not recommended for use with ductwork, filters, or other impediments to airflow in the fan air stream.
