Heat recovery modularization air conditioning system

The utility model provides a heat recovery modularization air conditioning system. The heat recovery modularization air conditioning system comprises a fresh air module, an air inlet module, an air return module, an air exhaust module and a heat exchange module. All the modules are independent of one another and are used for being spliced and combined into the air conditioning system. A fresh air section is formed by the fresh air module, the heat exchange module and the air inlet module which are adjacently arranged. An air return section is formed by the air return module, the heat exchange module and the air exhaust module which are adjacently arranged. The heat recovery modularization air conditioning system is small in occupied space and high in operating efficiency, all the parts are sorted and allocated, fresh air and return air are subjected to heat recovery, and thus energy is saved.
