Screw-Type Water Source Heat Pump

Heating & Cooling

R410a

Max. heating capacity: 238.7kw/h

01

High efficiency compressor

 

  •  Advanced twin screws compressor with optimum structure can  realize automatic stepless or 4 steps capacity control to achieve high efficiency.

  • Running noise is low thanks to low friction area inside the compressor.

  • The compressor has a long lifetime profiting from high performance of interior oil segregator.

02

New Condenser

 

 

  • It adopts the double-side reinforced condenser tube to optimize the tube bundle arrangement design in the condenser.

  • The unique design of the built-in oil separator helps address the problem of lubricating oil separation.

  • The product optimizes the subcooler design, improves the supercooling temperature, and reduces the pressure loss ofsubcooler, improving heat exchange performance efficiency.

  • This product implements uniform gas transmission without any heat transmission blind spots.

05

Quiet Operation

 

  • The sound level is as low as 65 dB(A) when the unit operates with a partial load.

  • A standard shock-absorbing cushion is configured between the compressor foot and the metal support, achieving a good damping effect.

  • The built-in discharge mufler for the compressor cuts off transmission from the sound source.

06

Intelligent Control

 

  • Intelligent load control: Real-time load changes are predicted according to historical data, and the real-time load is prospectively revised to avoid frequent fluctuations in the unit water temperature.

  • Safe and intelligent unit control: The system monitors the trends of change in the unit’s parameters and adjusts the operating status of the unit as necessary to ensure safe operation.

  • Intelligent failure response: When the unit fails, in addition to executing the corresponding protective measures, the fault parameters are recorded for manual inspection and troubleshooting.

07

Interface Display

Controller: MIC Interface display:7-inch touch screen Communication interface: RS485 Communication protocol: Modbus-RTU Protection measures: more than 20 protection measures include the power supply, compressor, pressure, and temperature.

08

Environmentally Friendly Refrigerant

 

R134a environmentally friendly refrigerant achieves high cooling efficiency, without destroying the ozone layer. The refrigerant complies with the Montreal Protocol.
