Development and prospect of central all-air air conditioning systems

Based on the analysis of the unitary split air conditioning system and variable refrigerant volume air conditioning system, considers that the scale-up production is the certain trend of central all-air air conditioning systems and to carry out the design and manufacture of this system in normalization, modularization and series is the key point. Puts forward a new type of air handle unit which can realize the scale-up production. Optimizing the system compositions and cancelling the secondary return air, the system can carry out the best energy using and conservation, and has merits such as simpleness, easy installation and maintenance and high reliability.
