Large temperature difference and partial second air independent dehumidification air conditioning is a new type of health and energy saving of the central air conditioning, adopting the  patent technology . 

The air conditioning adopt a part of the second air independentdehumidification.  Then  mix with first air to supply for room , belonging to the low temperature difference of precision air delivery, healthy and comfortable. In the summer, after the air through the sensible heat exchanger, part of the second air enter the latent heat exchanger to dehumidify. Then mixture with first air to supply. Because it need not  send the wind at a machine dew point, the temperature difference is low, the room temperature is also small , better comfort. In winter, the air go through duble heat exchanger in turn, energy can be effectively used, more energy saving.

Chiller use of large temperature difference and small flow cool water, summer entering water and return water temperature using 17 and 7℃, winter use 35 and 45 ℃, effectively reduce energy consumption of the conveying system , and improve the efficiency of the chiller. The main features are as follows:
Energy saving:
  The use of  patented technology of separation thermal and wet , energy full cascade utilization, effectively improve EER.
The use of large temperature difference between 10 degrees and small flow technology, the flow is only 50% of the traditional central air-conditioning, effectively reducing the transmission energy consumption of the pump.
To the whole system, compared with the same type of traditional central air-conditioning energy saving 30%.
Comfort:
  Air conditioning air temperature is different from the traditional central air conditioning, the use of the air temperature is higher than the machine dew point temperature, air temperature difference is small, the room temperature fluctuations
Smaller, control precision, high comfort.
Healthy
The traditional air conditioning uses the machine dew point to send air, easy to take the wet，to spay. And cause a vent condensation, easy to breed bacteria, poor health condition.
Because of the traditional air conditioning air temperature is too low, the temperature fluctuation is large, easy to get air conditioning disease.
Second independent dehumidification air-conditioning air temperature is high, it will not cause condensation, good health conditions, temperature fluctuations small, more conducive to physical and mental health.
Multi evaporation temperature
The refrigeration system uses a variety of  evaporation temperature, as far as possible to reduce the irreversible loss, improve the EER about 20%. .
Overall investment less
Due to the use of large temperature difference and low water flow for cooling and heating, reducing the air conditioning pipe diameter, reducing the pump power, so reducing the investment .
