Problems solved by technology

[0006] In North America, the sensible heat equipment of the independent fresh air system basically uses radiant panels. The main disadvantages are: a) condensation on the cold surface. When the surface temperature of the cold radiant panel is lower than the dew point temperature of the room air, the surface of the cold radiant panel will Condensed water will be generated; b) The cooling capacity per unit area is too low. Currently, the cold radiation panel with the best performance in the world has a cooling capacity per unit area of ​​only 140W/m 2 , generally 30~80W/m 2 , often the entire ceiling is covered with radiant panels, and the cooling capacity is not enough; c) the one-time investment is high; d) an automatic control system is required to prevent condensation on the cold surface
[0009] The common disadvantages of these two floor air supply syst

Abstract

The present invention is one air conditioner system with independent fresh air unit and variable blowing rate unit. The air conditioner system includes one fresh air unit with full heat exchanger, one air conditioner unit, one variable blowing rate box or terminal unit, one cyclonic air outlet, one temperature controller and one variable blowing rate controlling system. Compared with traditional air conditioning system, the air conditioner system of the present invention has over 50 % lowered power consumption, and possesses the advantages of high efficiency, low power consumption and health.

Description

technical field [0001] The invention relates to an air conditioning system, in particular to an independent fresh air floor air supply variable air volume air conditioning system. Background technique [0002] Due to the continuous power shortage situation, energy saving has become a major concern of various countries, and the energy saving of air conditioners is the first to bear the brunt. The energy saving of the air supply system of the air conditioning system is one of the most important factors affecting the energy saving of air conditioners. At present, the most commonly used air-conditioning systems in commercial buildings in the world are independent fresh air system (DOAS) and floor air supply system (UFAD). [0003] Independent fresh air system (DOAS) and floor air supply system (UFAD) are listed by the U.S. Department of Energy as one of the most energy-saving and promising air-conditioning technologies promoted in the United States. Its outstanding energy-saving...
