The Liebert VH138W-AA0S water-cooled air conditioning unit is a highly efficient and reliable HVAC solution designed for commercial and industrial applications. This upflow HVAC system, with a capacity of 10 tons, is engineered to deliver optimal cooling performance, ensuring indoor comfort in various environments.
Design and Construction:The Liebert VH138W-AA0S is an upflow water-cooled design, which means that the cooled water from the condenser is returned to the building's water source before the warmer water from the building's return system enters the condenser. This design allows for more efficient cooling and is well-suited for applications where external water sources are readily available.
The unit is constructed using high-quality materials to ensure longevity and durability. Its robust design consists of a screw compressor with a compressor motor having a superior energy efficiency rating as per IE3 standards, a hermetic scroll compressor for optimal cooling performance, and a capacitor starting motor for exceptional starting torque.
Cooling Capacity and Control:This water-cooled HVAC unit from Liebert provides a cooling capacity of 10 tons. The chiller cools the water entering the system to a low temperature, allowing the unit to efficiently cool the incoming air. The integrated thermostat control ensures precise temperature maintenance, while the compressor control maintains system efficiency by only running the compressor when necessary.
Power Consumption and Efficiency:The Liebert VH138W-AA0S is designed to minimize power consumption and maximize efficiency. It features a high-efficiency, low-leak scroll compressor and an Integrated Part Load Value (IPLV) control in compliance with EN 14511 standard for optimized energy usage. Furthermore, it is engineered to meet or exceed the minimum energy performance standards set by various organizations, such as ASHRAE 90.1-2016, Energy Star, and ErP.
Additional Features:- Built-in compressor and fan controls for energy optimization
