Scroll Modular Ground Source Heat Pump

This product closely follows the development trend of the times,adhering to the design concept of "efficient,reliable,energy saving,and environmental protection", and has become a newer and more economical excellent product provided to users.

Product Description

　　CTEDM series modular ground source heat pump is a new generation of ground source heat pump carefully developed by Shandong Zhongkeneng Artificial Environment Co.,Ltd.,which has gathered many years of ground source heat pump components and product design and production experience product.

It can be widely used in various comfortable central air-conditioning systems such as office buildings,hotels,hospitals,entertainment venues,factories,houses and so on.

　Features:

　　 1. It can replace the boiler room system during heating.There is no combustion process,which avoids smoke pollution.The cooling tower is omitted during cooling.The cooling tower noise and mold pollution are avoided,making the environment cleaner and more beautiful.

　　2. In the winter,1KW of electric energy can be used to obtain about 4KW of thermal energy;in the summer,1KW of electric energy can be used to obtain more than 5KW of cooling capacity,and the energy utilization rate is 3--4 times that of the electric heating method.

　　3. The boiler room and the associated coal yards and coal mines are omitted,saving land resources.

　　4. Taking water as the source body,it absorbs or releases heat to it to achieve heating or cooling.It neither consumes water nor causes pollution to it.

　　5. Through a system to achieve cooling and heating,the one-time investment is only 1/2-2/3 of the traditional cooling and heating investment;the operating cost is only 1/2-2/3 of the traditional method.

　　6. Energy saving and reliable

　　Multi-level energy regulation easily solves the practical problem of long-term cooling chiller that is low in cooling efficiency during partial load operation.Users can experience the benefits and happiness of energy saving when paying the electricity bill at the end of the month.

　　In modular installation,each module unit has unparalleled independence.Each module unit is an independent and complete refrigeration system.It operates in an orderly manner under the control of a computer controller.When one or more of the module units fails,it will not affect the operation of other module units,and allows users While the unit remains running,the faulty module is overhauled and maintained.

　　7. Easy installation

　　Make handling work zero and easy.The standard module units in the modular installation are assembled on the site.The entire transportation and handling process does not require large lifting machinery and special internal passages,and a large refrigeration unit can be easily delivered to the basement or roof of the building.

　　8. Flexible expansion

　　The flexibility of free expansion during modular installation allows users and designers no worries.The feature of modular installation and free expansion allows users to arrange purchases in stages and install in stages according to the needs of their own business development;Because the module unit can be arbitrarily added to expand capacity when needed in the future,without any additional costs in addition to the device itself.In particular,large-scale projects or renovation projects that are constructed in phases can be invested in phases in accordance with the funding situation to improve the utilization rate of funds.

　　9. Quiet running

　　The fully enclosed unit adopts a box-isolated design,multiple noise reduction processing,and the use of a low-noise fully enclosed scroll compressor.In the cooling mode,it has a quiet function at night and the vibration occupies the industry-leading level;Relying on the national precision noise room and noise spectrum analysis,the components were strictly compared,selected and improved,and the structure and piping were professionally designed to reduce noise,and the unit noise was significantly improved.

　　（1）The closed structure design eliminates the safety hazards of the refrigeration system and the electrical system being damaged。

　　（2）Advanced microcomputer control system,with full automatic control function,with protection items such as high and low pressure,overload,under voltage,phase loss,low temperature,etc.,and has an external water pump chain function to realize fault display and alarm.
