Environmentally-Friendly Refrigerant-Type Modular Air-Cooled Heat Pump Unit

Specifications:

Note:
■ Test conditions for nominal cooling capacity: nominal water flow for cooling mode; outlet water temperature 7°C; outdoor ambient
temperature 35°C.
■ Test conditions for nominal heating capacity: nominal water flow for heating mode; outlet water temperature 7°C; temperature of outdoor
dry/wet bulb: 7°C/6°C.
■ Water resistance at the air conditioner side includes water pressure drop of the unit and the attached Y-shaped filter.
■ The operating weight of the unit is about 1.05 to 1.1 times its net weight.
■ The water main of the modular unit needs to be customized and installed on site. The diameter of the pipe must meet design requirements.
EK does not provide the pipe.
■ Modular units can be formed using 1~16 basic modules of the same model or different modules as required. The above table lists the
parameters for common module combinations formed using 1 to 5 modules.

Description:

1. The 130 kW modular unit saves investments on water systems. Compared with two 65 kW modules, one 130 kW modular unit saves the investment on the pipeline and accessories of one water system.

2. Compared with a combination of two 65 kW modules, one 130 kW,  modular unit saves the land area by 14%.

3. The 130 kW modules support seamless installation and save the land area by 30% compared with 65 kW modules when multiple modules are combined during installation.

4. Sixteen 130kW modules may be combined, which easily expands the capacity of an air-cooled modular unit from 130 kW to 2080 kW.

5. The unit inherits the advantages of the 65 kW module, and uses the precise flow control technologies by using electronic expansion valves and efficient plate-type heat exchangers. The system performs optimal matching to ensure that the energy efficiency of the unit is above the energy performance certification standard of.

6. The RoHS certified environment-friendly galvanized steel sheet and 120μm-thick orange-peel spraying endow the unit shell with anti-erosion, hard fall-off, and slow fading. This makes the unit work a long time.

7. The unit adopts high-performing inner grooved copper pipes provided by well-known suppliers, which help the refrigerant form liquid film on the inner walls of the pipes, greatly increasing the heat exchange efficiency.

8. Compared with the traditional air-cooled modular unit that uses a thermal expansion valve, EK air-cooled modular unit uses 500-step PMV electronic pulse for precise adjustment to implement precise PID control. The system implements real-time matching and precise water temperature control, fully improving the optimal performance of each component inside the system. This makes the unit operate steadily at any workload and automatically adapt to varying ambient temperatures, solving the oscillation issue of a cooling system. In addition, the temperature output of the system is more steady, and the indoor temperature is more balanced, improving comfort.

9. The genuine dual-system panel-type heat exchanger can bear a 3.0 MPa pressure at the water side, and provide the pressure bearing capability for a water system in a high building. Compared with a shell-and-tube heat exchanger, this heat exchanger delivers higher heat exchange efficiency, and provides a cleaner internal environment. Compared with a traditional back-to-back heat exchanger, it provides higher heat exchanger efficiency and delivers higher anti-freeze capability at partial workload. When operating at partial workload, it provides higher heat exchange efficiency. A standard configuration provides a water pressure drop switch to monitor the unit water flow in real time as well as precise anti-freeze control.

10. Different from a traditional secondary pumping system, the primary Pumping Variable Flow System features variable flows at the refrigerant side and workload side and shares one transducer pump group. Its flow may drop with the workload of the air conditioner, greatly saving the operating expenses for the chilled water pump of the air conditioning system.

11. The unit may send out 2-way valve water control signals to cut off chilled water. This enables automatic flow control for pumps in line with the transducer, which helps easily implement primary Pumping Variable Flow System.

12. It is applicable to projects where the cooling workload of the air conditioner changes greatly, and the air conditioner works at partial workload for a long time.

13. Compared with the secondary pumping system, it saves the initial investment on the cooling water pump and pipes at the primary pumping system and on the power distribution system, and requires a smaller area
