Supply-Small rooftop air conditioner 5ERSN series

The series is the fifth generation of small integrated rooftop air conditioners newly developed by Yilong based on the original series. All units are designed and manufactured in accordance with the /3-standard and have been rigorously tested in the enthalpy difference laboratory of Yilong factory to ensure excellent performance in the outdoor -℃-℃ working environment.

The series has three standard models:
< Single cooling type, heat pump type, constant temperature and humidity type, the whole series adopts high-efficiency double-layer sheet metal structure
< Sealed - Smooth and flat inside, no dust, no air leakage. Dry - No metal channels between double-layer metal sheets, no cold bridges. Quiet - Better sound insulation than fiberglass. Strong - Double-layer metal structure is not easy to deform. High efficiency value is glass. Twice the fiber's applicable scope
All R series are designed as high static pressure models. Longer ducts can be used for air supply, making design and installation more flexible.
Product Features Capacity R series has more than twenty varieties of cooling capacity - heating capacity. - Such a wide range of varieties can meet the air conditioning needs of many small and medium-sized places.
The unit has two or more independent refrigeration systems, which can automatically turn on one or more systems according to load changes, which is particularly energy-saving. The heat exchanger uses internally threaded copper tubes and aluminum foil mechanical expansion to greatly improve the heat transfer efficiency. The use of expansion valves allows the unit to operate within a wider range and always ensure high efficiency.
The use of adjustable pulleys can meet different indoor air supply requirements. All fans are statically and dynamically balanced tested. The inclination direction of the impeller and the design of the volute have been rigorously tested many times to obtain the lowest noise and a wider air volume and pressure range.
The casing is made of high-quality galvanized steel plate and painted and has been tested in salt water for at least an hour to comply with the test procedures, making the whole machine resistant to all harsh environmental conditions. The axial flow motor has a fully enclosed design, high-grade insulation, high temperature resistance, and can adapt to various climate conditions.
The refrigerant charging of the series units has been completed at the factory, and only the air ducts and single-point power supply need to be connected on site.
All coils are mechanically expanded with internally threaded copper tubes and aluminum foil. A large area condenser is the basic design concept. The increased coil area makes the whole machine more efficient than the old machine
Using advanced micro- processor. The large high-definition LCD screen clearly displays various operating parameters of the unit, and can be set for a week, displaying indoor air, coil temperature, outdoor air, and coil temperature. Monitor the operating status of the entire machine. Powerful programmable function automatically adjusts operating conditions according to the program.
Economic control option
If the outdoor temperature is lower than the indoor return air temperature, the compressor will automatically stop running, the economizer will automatically open the fresh air valve, and at the same time the return air valve will automatically close, and the outdoor air will directly enter the room. Pre-cooling is particularly energy-saving. At this time, only the fan is running, reducing operating costs
