Industry-Level Air-Cooled Precision Air Conditioning

Introduction

The industry-level air-cooled precision air conditioning series is designed for high heat density computer rooms and micro-module configurations. It can cool close to the heat source, reduce the distance between the return air and the return air temperature, and adjust the output of cooling capacity according to the load changes. It has the characteristics of high sensible heat ratio and high energy efficiency ratio. Full frequency conversion design, with the electronic expansion valve to accurately adjust the flow rate, adapt to different load changes. Achieve 30%-100% variable capacity output and precise temperature control. The 7-inch color touch screen realizes the display of the operating status of each component, and can realize intelligent group control of 32 units to ensure the stable operation of the entire module. According to the load changes, the EC fan speed is dynamically adjusted, and a variety of control methods are optional to ensure system energy saving. Standard RS485 interface and water leakage alarm.

Application

Applied to modular data computer rooms, container data centers, high heat density data computer rooms and other fields.
