Copeland (USA Emerson) compressor:
High efficiency, stable performance, and special designed for heat
Long life (at least 15 years) and free from normal working abrasion
Various protection systems, which ensures the heat pump running
under smooth condition.
Over current protection, Over temperature protection
High voltage and low voltage protection.
Resisting the liquid hammer strongly and run steadily on bad
Great Noise isolated material
By using high quality aerial noise isolated material, noise and
vibration is avoided perfectly.
Good inside Layout
Well selected axial T6 fan motor combined with large fan blade,
which provide heavy air blow at low rotate speed, reducing
vibration and noise.
High Efficient Tube in Shell Condenser (heat exchanger)
Optimize design of both inner and outer screwed tube, it helps to
increase heating exchange efficiency, and provide better heating
capacity. The special design of liquid refrigerant circulating tube
on the bottom of condenser ensures the heat pump system run
smoothly in severe working condition.
And also TRT heat exchangers are designed with double coil design,
which water flows inside the coil and refrigerant runs outside the
coil. And their strong countercurrent design are helpful for
improving the efficiency and not easy to freeze and scaling for the
Eaton (USA) AC contactor and Thermal relay
High quality contactor and thermal relay can freely turn on/off
more than 100,000 times.
Wide voltage transformer
By using 220V-240VAC,50/60Hz wide voltage transformer in case of
voltage fluctuation, ensure unit work smoothly. Current transformer
protecting over-current ensure unit working current more accurate.
The temperature sensors detect the ambient temperature correctly,
and transfer the information to the controllers accurately.
When the temperature sensor detect the ambient temperature is low
enough, heat pump system will turn to four-way valve automatically,
then the units begin to defrosting.
The air exchangers(fins-coil) with hydrophilic coating have high
efficient heat exchange, after salt fog testing, prove that these
exchangers also have strong anti-corrosion feature.
TRT adopt the world’s famous brand expansion valves, which control
the volume of the refrigerant accurately and reduce energy
