Why choose Fresh Air Free Cooling Air Conditioner?


Aspects   in contrast

General   split air conditioning

 

Free-cooling   All-in-one Type Air Conditioning

 

Industrial practicality

Design based on human physiological   characteristics; The indoor air flow is less than 1000m3 / h, and the   temperature difference between the inlet and outlet air is large;

 

 

Designed based on the working   characteristics of electronic components, the temperature difference between   the inlet and outlet air is minor, the temperature drops slowly, and the   indoor temperature is uniform;

 

Dehumidification, 50% - 70% sensible   heat accuracy;

 

Light dehumidification, 85% - 95%   sensible heat accuracy;

 

Unable to meet various industrial   standards; It is difficult to start in winter in low temperature area;

 

 

Base station dedicated air   conditioning, natural cooling function to achieve energy saving, 1 / 3 time in   a year can use natural cooling in most areas;

 

Safety of use

With outdoor machines, not   convenient for high-rise maintenance, not safe, not anti-theft; Split   structure, refrigerant is easy to leak.

 

 

No outdoor machine, easy to guard   against theft, installation and maintenance, refrigerant is not easy to leak;

 

There are many plastic parts in   indoor unit, which are easy to produce static electricity;

 

The shell of the unit is a metal   part, which is not easy to produce static electricity;

 

Ease of use

No intelligent control system, need   daily management;

 

Remote monitoring function, Intelligent   control, no need for special management;

 

Economy of use

The refrigeration function runs all   year round with high cost and fast loss;

 

Long working life.
