Shanghai Yilong Supply-Large Multifunctional Rooftop Air Conditioner 5ERL Full Heat Recovery Type

The R series is a powerful, high-efficiency and energy-saving large-scale integrated multi-functional rooftop air conditioner. Due to the continuous advancement of technology, there is an increasing demand for high-efficiency and energy-saving large-scale multi-functional rooftop air conditioners. R series large rooftop units are a new generation of air conditioning products developed by Yilong based on its exquisite production technology and rich experience in the field of air conditioning. Yilong R series rooftop air conditioner is an all-air system with no water pipe system and terminal equipment. It does not require a machine room. The evaporator directly cools the air, avoiding the energy loss in the refrigerant-water-air transfer process in traditional air conditioners. And the evaporation temperature is higher than that of conventional systems, so the refrigeration energy efficiency is relatively high. The R series has very powerful functions. It is a rooftop air conditioning unit that integrates cold source, heat source, exhaust air, fresh air, and heat recovery. It can be placed with a variety of filters (primary effect, medium effect, high efficiency, etc.), and a variety of heating methods (electric Heating, hot water, steam, natural gas, etc.), a variety of humidification (electrode, wet film, steam, etc.). In addition to standard models, Yilong also has the following three models:
Smooth operation
Copy of large multifunctional rooftop air conditioner/>
The use of volute-less centrifugal fans can meet the requirements of different air supply directions. All fans are statically and dynamically balanced tested. The inclination direction of the impeller has been rigorously tested many times to obtain the lowest noise and a wider range of air volume and pressure.
Durable
bThe casing is made of high-quality galvanized sheet paint and has been tested for at least 1 hour of salt spray corrosion in compliance with the test procedures, so that the whole machine can withstand all harsh environmental conditions. The external fasteners are made of stainless steel. The axial flow motor is a fully enclosed design, with high-grade insulation, high temperature resistance, and adaptable to various climate conditions.
High-quality thermal insulation
b The body of the machine is made of thick double-layer sandwich steel plate structure and lined with thermal insulation materials, which greatly improves the thermal insulation performance of the whole machine and ensures that no dust particles enter the indoor air.
Convenient maintenance
The b unit is equipped with many access doors. The boxes where the core operating components of all models are located can be stepped into. It is spacious and bright, making it easy to inspect the compressor, fan, control components and filters. wait.
Refrigerant
b All R series units have been filled with refrigerant at the factory, and only need to connect the air duct and single-point power supply on site.
Coils
All coils are mechanically expanded with internal threaded pipes and aluminum foil and have undergone 3/pressure test and helium leakage inspection to ensure there is no leakage. The increased coil area makes the overall machine more efficient than the old machine.
Compressor
b adopts a fully enclosed and high-efficiency scroll compressor. Equipped with a thermal protector and oil heater, it has a normal operating life of up to several hours, no vibration and low noise. State-of-the-art oil-free magnetic levitation compressors (, ) are available when required.

.Coated coil, anti-corrosion inspection light
3. Low temperature operation - in low temperature environment, The speed of the condensing fan or motor is adjustable, and is also equipped with a relay that bypasses the low-pressure switch when the compressor is started.
.Hot gas bypass-provides anti-freeze protection for the evaporator under low-pressure load operating conditions
Advanced microprocessor
Large high-definition LCD screen clearly displays various operating parameters of the unit . It can be set for a week and displays indoor air, coil temperature, outdoor air, coil temperature and other parameters. Remotely monitor and manage the operating status of the entire machine. Powerful programmable function automatically adjusts operating conditions according to the program. On-site or remote microprocessors are compatible with B, b and protocols.
When the enthalpy value of the outdoor fresh air is lower than the indoor return air enthalpy value or closer to the set enthalpy value, the compressor will automatically stop running, and the economizer energy-saving device will automatically open or increase the opening of the fresh air valve. The return air valve automatically closes or decreases synchronously, and outdoor air directly enters the room. At this time, only the indoor fan is running, which is particularly energy-saving.
