Standard comfort type AHUs support the filter, cooling coil, and fan sections. By installation method, they can be classified into floor type units and ceiling type units. Floor type units are further divided into horizontal type (7 models) and vertical type (1 model), and the air volume ranges from 2000 to 50,000 CMH. Ceiling type units cover conventional type, jet type, heat recovery type, fresh air type, cool warehouse special type, and industrial large space special type, and the air volume ranges from 1000 to 10,500 CMH. Standard units are widely used in common comfort type places such as shopping malls, hotels, office buildings, supermarkets, factories, workshops, stadiums, and departure lounges.
Polyurethane foamed under high pressure and sealing strips contribute to AHRI1350 CB2 (among CB0~CB4) cold bridge factor; sheet metal edges are protected to avoid rusting.
Optimized structure for the full series, less installation space is required.
Standard order processing, sufficient stock, fast delivery.
Simple mechatronic control configuration, energy efficient and comfortable intelligent control.
For ceiling-mounted units, DC fan is optional. There is no need of belt replacement. The filter is installed through connecting clips, which is easier and facilitates replacement.
Standard models feature complete series and various functions.
The cabinet panel adopting overall foam molding technology is surrounded by an aluminum alloy profile frame with concave and convex grooves. When installed, it forms a labyrinth sealing structure in tenon form, with the concave and convex modules interlocked. Fastened by bolts and embedded nuts, a labyrinth-type sealing cabinet with strong torsion resistance is formed. The mechanical strength rating of the cabinet can reach AHRI1350 CD4 and air leakage rating can reach AHRI1350 CL1 (1/66 of the value as required by national standard).
The coil is integrated with quality RoHS-certified copper tubes and unique corrugated aluminum fins through the advanced mechanical expansion tube process.
The coil passes air tightness test before delivery to ensure no leakage. The heat exchanger is designed using the professional model selection software certified by AHRI to ensure that model parameters are consistent with performance of the actual heat exchanger and the heat exchanger can address model selection requirements of customers in different operating conditions.
Mechanical & electrical integration control enables integrated control of fan, motor, and water valve. The control system is composed of low-voltage apparatuses and temperature controllers from internationally well-known brands. If the unit is equipped with a temperature controller with communication function, the unit can access third-party control systems, such as a building automation and control system, to enable remote and network-based unitmonitoring.
The control cabinet is equipped with multiple protection technologies, such as power supply misphase, power supply phase loss, and current overload, to ensure that the unit operates stably. In addition, the unit reserves diversified external interlocking. Integrated control can save energy of the chiller, while ensuring comfortable room temperature.
