PRECISION AIR CONDITIONING UNITS
Compact direct expansion precision air conditioners equipped with microchannel evaporators for increased capacity and enhanced efficiency
Applications: Server rooms • Clean rooms • Telecom • Banking • Government • Entertainment
Compact DX is the range of ultra-compact precision air conditioning units with enclosure depth as low as 490mm. Despite its narrow design, the Compact DX units feature all the functionality of full-sized cooling units and offer the customers a wide range of options and accessories. This, as well as small footprint, lightweight construction, and easy installation, make Compact DX ideally suitable for retrofit and space-limited applications.
Equipped with microchannel evaporator, Compact DX ensures the highest possible energy efficiency within its cooling capacity range. Inter alia, this cooling solution provides an excellent balance of high predictability, high power density, adaptability, and the best overall TCO.
Compact DX air conditioning units based on newly developed microchannel evaporators with an advanced design that combines high-performance flat tubes, state-of-the-art airside fins and ultra low-pressure manifolds with integrated refrigerant distributors.
The unique geometry of the manifolds and refrigerant distributors make it possible to feed the microchannel tubes equally for evaporation and ensures consistent and predictable heat transfer. Vertically-oriented microchannel tubes allow free condensate water shedding.
Microchannel evaporators permit numerous benefits to be achieved, including low airside pressure drops, higher cooling capacity, significantly reduced weight and minimum refrigerant charge.
OPTIMIZED FOR REFRIGERANT R410A
The scroll compressors employed in our air conditioners’ design are the result of large-scale research and development efforts underway since 1979. These efforts have led to the production of the most advanced scroll compressor design currently available for air-conditioning applications.
Significant design improvements adopted in the latest scroll compressors reduce the load on mechanical parts, provide safer operation at high condensing and evaporating temperatures, improve compressor robustness in low lubrication conditions (e.g., at unit start-up), while on-board electronics provides compressor protection.
The customers of Compact DX systems with R410a-optimized scroll compressors can benefit from the quiet operation, unmatched reliability and low operating cost.
Refrigerant circuit of the Compact DX unit equipped with electronic expansion valve (EEV) which regulates and optimizes the refrigerant quantity to the evaporator based on current requirements. Through the use of microchannel evaporator, the refrigerant charge of the Compact DX air conditioners significantly reduced in comparison to old-style fin/tube designs. Compact DX features refrigerant leak detection system, fast becoming a high priority for many customers, especially considering the potential for loss if a major leak renders a cooling system inoperable.
All the components of unit’s refrigerant circuit are located within the separate compartment, thus allowing easy access for maintenance and servicing.
FLEXIBILITY IN APPLICATIONS
The control system of Compact DX air conditioners is the latest generation controller with the logic specially developed for direct expansion precision cooling units. The software offers advanced control functionality for stand-alone and network operations, monitoring and diagnostics capabilities – locally or remotely.
Users can adopt various control strategies based on either continuous temperature control, or on-demand airflow control, or constant pressure control by maintaining a pressure differential between the cold and hot aisles.
QUIET AND ENERGY-SAVING
Compact DX features new radial fans with unique blade geometry and offers increased airflow based on reduced size and wider efficiency range. In combination with EC-motors with integrated control functionality, a communication interface, and overtemperature protection, these fans provide unbeatable energy efficiency, maximum flexibility, and the lowest possible sound emission. EC motor technology produces significant savings at both full load and part load operation. EC-motors are maintenance-free and have a longer lifetime in comparison to brushed motors. The fans are also fully compliant with the requirements of Energy-related Products (ErP) 2015 Directive.
Compact DX units are available in downflow or upflow configuration.
