Rooftop air conditioning cooling mode:

The outdoor fin heat exchanger is used as a condenser, and the indoor fin heat exchanger is used as an evaporator. The high-temperature refrigerant gas discharged from the compressor is condensed into liquid in the outdoor fin heat exchanger, and is throttled and reduced by an expansion valve. It becomes a low-temperature gas-liquid mixture, and then flows into the indoor fin heat exchanger, absorbs heat and evaporates, returns to the compressor to complete a refrigeration cycle; at the same time, the return air (or fresh air) from the indoor passes through the indoor fin heat exchange After the evaporator (in this case, the evaporator), it is cooled down, and the treated cold air is sent into the room by the indoor side fan.

Direct expansion air conditioning units are widely used, and rooftop air conditioning units are widely used in supermarkets, shopping malls, conference and exhibition centers, theaters, stadiums, factories and other occasions where centralized air treatment is required.

Product features: 1. DX Rooftop central air conditioner units is the roof type air-conditioning unit has its own cold and heat source, which is air-cooled direct evaporative expansion air-conditioning equipment. The entire air-conditioning system is only composed of outdoor hosts and indoor air ducts, without cooling water and chilled water systems. It is easy to install and use, saving User investment, especially suitable for water-scarce areas.

2. The roof air-conditioning indoor system has no moving machinery and water pipes, which avoids noise and water leakage.

3. The roof air-conditioning unit （DX Rooftop central air conditioner units ) is designed to be installed on the roof or in the outdoor open space. It has the performance of anti-sun exposure, anti-corrosion and rain-proof, and can save the cost of air-conditioning machine room and civil engineering.
