螺杆式地源热泵

Screw type ground source heat pump

螺杆式地源热泵
Product Description
 Features

  CTEDB series of ground source heat pump products are mature stereotyped products developed by Shandong Zhongkeneng Artificial Environment Co.,Ltd.on the basis of fully absorbing the latest development technology in the international and domestic refrigeration and air conditioning field.The unit is designed and manufactured strictly in accordance with international industry standards.The unit uses high-quality,high-reliability compressors,refrigerant system control components and computer control components produced by world-renowned manufacturers.


Application

     1.The temperature range of the water source used by the unit is wide:10~35℃
   2.It can provide 7℃or 50℃air-conditioning hot and cold water,as well as domestic hot water.
   3.It can also be used as a heat source for urban area heating
      It is widely used in office buildings, hotels, hospitals, entertainment places, factories, residences and other comfortable central air conditioning systems.

 Optimized design
    ■ Designed in full compliance with international standards and combined with China's actual conditions.
  ■ The technical idea of"large temperature difference and small flow"can save users the precious water resources to the maximum.At the same time reduce operating costs.
  ■ Computer-assisted optimal design ensures that the unit is in the best operating state under any operating conditions.
  1、Separate the strong and weak electric control systems to ensure maximum safety
  2、High-pressure elastic system design,greatly extending product life
  3、Precision rotor machining technology,efficient and robust moving parts
  4、Multiple energy extraction methods,make full use of customer resources
  5、The optional heat recovery design truly reflects the multi-purpose use of the machine;while cooling,the domestic hot water is made to achieve the purpose of value-added enjoyment.

 Good quality
  1、The original imported compressor has the most advanced twin-screw structure,which has extremely small unbalanced rotation force and extremely low vibration and noise.Partial load operation is balanced and high efficiency.
  2、Adopting the most advanced DAE/DAC high-efficiency heat transfer tubes,multiple spiral thin ribs and spiral protrusions on the heat transfer surface,the heat transfer coefficient and heat transfer capacity are greatly improved.
  3、The refrigeration system accessories used in the unit are all selected from brand-name manufacturers,such as detachable drying filters,external balanced thermal expansion valves,liquid supply solenoid valves,sight glasses,high and low pressure controllers,etc.to ensure that the unit has an excellent level of performance.

 Simple and reliable operation
      1、Full computer control and backup manual operating system。
  2、Perfect computer control and multiple protections make the whole machine safe and reliable.
  3、Adopt advanced high-speed embedded microprocessor,which runs fast.
  4、The short message function control is reserved,and the user can easily control the unit through the short message of the mobile phone.
  5、PC monitoring system is reserved.Users can implement PC monitoring through converter and adding PC software.
  6、With self-diagnostic capabilities,hardware faults can be automatically eliminated,and the software uses redundancy,trap technology and hardware WATCHDOG to improve the overall anti-interference ability.
  7、Adopting advanced touch technology,its touch screen has good touchability,and the life of continuous touch at each point is more than 1 million times,which guarantees the life of the whole machine
  8、It adopts independent power supply mode to realize power supply isolation and strong anti-interference.
  9、External interlocking function can be realized to ensure the safe operation of the unit.
