What are the characteristics of rooftop air conditioning units?

1. Wide scope of application
This series of products includes constant temperature and humidity type, heat pump type, cooling and heating type, cold air type and other series. The constant temperature and humidity type unit can meet the requirements of places with high temperature and humidity. The heat pump, cooling and heating type, and roof-mounted air conditioning units can meet the comfort requirements. In particular, the heat pump type unit can be used for two purposes, which greatly saves heating operation costs. It can easily meet the needs of air-conditioned places with large spaces and large air volumes.

2. Saving investment and easy installation.
The unit is an all-air system and can be installed on the roof or outdoor space without a machine room, saving building space and civil construction costs. The unit does not have cooling or chilled water systems, which saves investment in cooling towers, water pumps, pipelines and other ancillary equipment, and reduces project costs. When installing user equipment, you only need to connect a small number of control lines, power lines, and supply and return air ducts to put the unit into operation, saving construction time and costs.

3. The direct-expansion high-efficiency, energy-saving and low-consumption
unit adopts a direct-expansion high-efficiency circulation system that directly exchanges heat between refrigerant and air. There is no intermediate link for indirect heat exchange in the chilled water system, which reduces losses. The energy utilization of the entire air conditioning system is 10% to 15% higher than that of the chilled water air conditioning system. In addition, each unit has multi-level energy regulation, which automatically increases and decreases load to adapt to load changes on the user side. In transition seasons, the unit can operate with fresh air, saving energy, lowering consumption, and reducing operating costs.

4. Quiet operation and ultra-low noise
The unit adopts a low-noise fully enclosed flexible scroll compressor and is equipped with a patented bowl-shaped shaft-disc noise-absorbing direct-coupled transmission large twist angle and low-noise axial flow fan. Other moving parts of the unit have adopted complete isolation measures to ensure smooth and reliable operation, low noise and small vibration. The unit is installed outdoors, and there are no moving parts such as fans in the air conditioning system, so the indoor air supply is quieter.

5. Green air, quality assurance
The unit's efficient air filtration and adjustable fresh air device, coupled with multi-functional air treatment, can easily realize functions such as air purification, cooling, dehumidification, heating, humidification, and fresh air volume adjustment. The direct expansion circulation system has unique low evaporation temperature and low dew point processing characteristics, ensuring the quality of process parameters at any period. The fresh air operation during the transition season and the dry water tray design of the unit eliminate humid environment, making the air supply healthier and greener.

6. Unique structure, outdoor-specific
integrated unit design, compact structure, non-cold bridge insulation board structure, carefully designed unit frame, simple and lightweight, elegant appearance, large operating space, the unit can realize conventional transportation without over-width or over-height. The entire process of automatic spraying line processing of structural parts, plastic spraying, and aluminum alloy frames, and high-pressure foamed color steel insulation panels have good thermal insulation properties, are non-toxic, odorless, and have good self-extinguishing properties, and no condensation will occur on the surface during operation. The unique rainproof structural design of the special outdoor type ensures that the unit is anti-corrosive and anti-rust when used outdoors, and there is no risk of rain leakage.

7. Diverse functions and flexible layout.
The air treatment function of the unit has absorbed the most mature combined air conditioning technology at present. Users can select various function combinations according to actual needs on site. In addition, there are more than ten combinations of air supply and return of the unit, as well as integral or split on-site installation methods of the unit, as well as the selection of explosion-proof functions in specific places. It can meet the user's use under various environmental conditions, making the user's selection, design, installation and layout convenient, flexible and free.
