The rooftop air conditioner concentrates the fresh air and return air, and all the components of the refrigeration system are in a box, and the processed air is directly sent into the room through the air duct, so it is also called direct expansion AHU. The rooftop precision air conditioner can provide constant temperature and humidity. It is available for the place which has high requirements for the temperature and humidity.

The unit adopts a direct expansion high-efficiency circulation system with direct heat exchange between refrigerant and air, and there is no intermediate link of indirect heat exchange of chilled water system, which reduces the loss of energy utilization of the entire air conditioning system and increases 10%~15% compared with the chilled water air conditioning system.In addition, each unit has multi-stage capacity regulation, automatic load increase and decrease to adapt to the load change on the user's use side, and the unit can run with fresh air in the transition season, saving energy and low consumption, and reducing operating costs.

The integral multi-functional roof machine can be installed on the roof or outdoor space, without the need for a machine room, saving building space and saving installation costs.The unit has no

chilled water system, which saves the investment in auxiliary equipment such as cooling towers,

pumps, pipelines, etc.,and reduces the project cost. When the user equipment is installed,only a small number of control wires and power lines and air supply and return air pipes need to be connected to put the unit into operation, saving construction time and costs.
