Features and Benefits ( Centrifugal chiller R134a ) 

 

1. High Efficiency

Under  the AHRI conditions, Midea Dual-stage Falling-film Centrifugal Chiller has a COP up to 7.06 W/W.

  

 

 

2. Dual Stage Compression Technology

• Enhances the heat absorption capacity of refrigerant, and lowers the power consumption, which increases 6% of efficiency over the single stage compressor. 


• Dual stage impeller is an equal ratio compression design, which helps to reduce the rotate speed and enhance the reliability.


• Unique three-stage separation economizer simplifies the system design

 

 

3. Creative Heat-exchanging Technology

 

• Full falling-film evaporating technology

• Condenser

 

4. Free Cooling Technology-Refrigeration Migration

• Midea 3G Centrifugal Chiller features the ‘Free Cooling Technology’.

 ♦ When the outdoor temperature is low and large commercial buildings’ interior spaces may need cooling, the main unit will work on ‘Free Cooling’ mode. Free cooling is the production of chilled water Without running compressor.

 

♦ The relative warm, and the energy is carried directly to the low pressure condenser, where it is cooled and condensed by the water from the cooling tower. Then the low temperature liquid refrigerant flows to the evaporator driving by gravity, then naturally circulates.

 

♦ The cost is saved due to the compressor’s inactivity, zero power consumption of the main unit. The principle is that the refrigerant tends to move towards the coldest point in a refrigeration circuit. It can be used generally in the transition season such as late fall, winter and early spring.
