Main performance characteristics of air-cooled heat pump unit RTXA+: Under the national standard conditions, the unit energy efficiency ratio COP is up to 3.0, the ambient temperature is higher than 40OC and normal cooling, and the ambient temperature is lower than -10OC. The noise reduction measures are advanced, and the defrosting process is stable and energy-saving. The CH530 controller with Chinese touch screen is installed, with adaptive control function, feedforward control function, remote operation and group control function, which can directly communicate with third-party control system through LonTalk protocol.
â—†High reliability
The twin-screw compressor has fewer moving parts and uses 5-stage aerospace bearings for high reliability.
Direct drive low speed motor, suction cooling motor, long service life of the motor.
Strong resistance to liquid slamming.
The electronic expansion valve regulates the flow of the refrigerant and uses adaptive control logic to provide a more stable operation in the event of constant changes in system load and pressure.
â—†High efficiency and energy saving
The CHHN screw compressor is machined by precision machine tools with tight clearance and high operating efficiency.
The screw compressor adopts stepless adjustment of the slide valve, and the partial load efficiency is increased by 15~35% compared with the stepwise adjustment.
Double circuit design, part load is more efficient.
The electronic expansion valve precisely regulates the flow of the refrigerant, and the partial load efficiency is high.
W type air-cooled condenser design, high heat exchange efficiency.
â—†Advanced control
CH530 controller with Chinese touch screen
New feedforward control, cold water outlet temperature is more stable
Adaptive control, unit operation is more reliable
Communicate with the Tracer Summit system or communicate with third-party control systems via the LonTalk protocol
Remote operation function: unit start and stop, hot and cold switching, water temperature setting, etc.
Numerous parameter display and fault diagnosis functions for easy unit operation and maintenance
â—† Easy to install
The integrated unit design is flexible and convenient to install. It can be directly installed on the roof or outdoor space, eliminating the need for a dedicated machine room and saving installation space.
It is fully charged with refrigerant and lubricating oil at the factory. It is only necessary to connect the cold water pipeline and power wiring in the field installation.
According to market demand, Trane Air Conditioning Co., Ltd. introduced a new air-cooled heat pump unit RTXA+. This model has an innovative heat transfer design. Compared with the original model, the unit has higher energy efficiency ratio, more reliable operation, more compact structure and less space for heat dissipation.
