Advantage of package rooftop air conditioning units:
No water system, no secondary heat exchange, no large computer room and control, simple installation and construction
The difference with other air conditioning units:
1. Good sealing, heat preservation and pressure bearing performance (low air leakage rate, low deformation rate, no cold bridge);
2. Avoid secondary pollution (dry water tray, hydrophilic membrane surface cooler, no belt dust, no bacteria breeding)
3. Adjustable air volume (fan motor frequency conversion);
4. High filtration level (primary, middle and sub-high efficiency);
5. Complex functional sections (filtration, cooling, heating, dehumidification, humidification, noise reduction, disinfection);
6. The front wind speed should not be too high;
7. Centralized control is required (reserved information panel interface).
1, Frequency conversion technology: The DC frequency conversion compressor is used to adjust the operating frequency of the compressor according to the temperature change, which is efficient and energy-saving
2, Low ambient temperature cooling: The outdoor unit adopts EC fan, and the speed of the outdoor fan is controlled by the condensing pressure sensor to achieve -20℃ low temperature cooling operation;
3, Low temperature air supply: Shenglin's unique technology, through the grading and separate control of the evaporator, reduces the evaporation temperature, and the minimum air supply temperature is 5℃;
4, Precise temperature control: electric reheating and electric preheating are steplessly adjusted by SCR to accurately control the indoor temperature
5, Low ring temperature heating: advanced air jet enthalpy technology, normal heating operation at an ambient temperature of -20°C.
Multi-function: four-pipe, frequency conversion adjustment, cooling and heating operation can realize energy recovery at the same time, no need to add a hot water tank to adjust the water capacity on the hot water side;
Low-temperature heating: Adopting jet enthalpy and high-temperature liquid injection technology, heating operation at minus 20℃, and energy efficiency ratio higher than 2.1;
Low temperature refrigeration: EC fan is used to detect the discharge pressure of the compressor to achieve normal refrigeration at -20°C,
Cooling and heating balance: automatic cooling and heating balance under partial cooling and heating load, automatic distribution of refrigerant flow;
System stability: Adopting single four-valve design, consistent operation, mature system technology, stable and reliable operation;
Energy saving and environmental protection: annual heat recovery can be realized, energy recovery can be adjusted, cooling energy efficiency ratio ≥ 4.0, while heat energy efficiency ratio ≥ 5.0, combined cooling and heating energy efficiency ratio ≥ 9.0, operation energy saving effect is more significant ；
Intelligent control: Microcomputer PLC control technology, automatically detects the operating status, and realizes energy-saving operation;
Fault self-check: automatic fault detection system can detect operation faults such as suction and exhaust pressure, exhaust temperature, phase loss and reverse phase, overcurrent and overload;
Unique technology: the perfect combination of single four-way valve design, ultra-low temperature heating design, low temperature refrigeration design, and stable mode conversion.
