IN-ROW AC Series – Chilled-Water

Technical Data:

Frame Structure Description：

The overall frame and bottom plate of the unit are made of galvanized steel sheet whose outer surface has been electrostatically sprayed, so that the unit as a whole is not suitable for rusting. The unit structure is convenient and compact, occupies a small area of the machine room, saves space, and the unit supports full frontal maintenance. In the electric control box of the unit, the strong and weak currents are separated, and the high-power components such as electric heating and humidification are equipped with independent circuit breakers. The unit supports upper and lower pipes and upper and lower wiring, which is convenient for installation.

Control Cabinet：

It is placed on the top of the unit (can be pulled out) or the upper end of the fan, and supports frontal maintenance of electrical components, which is simple and convenient.

Control System：

Using the new generation of CAREL controller, it has a good man-machine interface, excellent control adjustment function, strong expansion ability, monitoring and management ability and strong compatibility. Multiple expansion accessories to increase remote and group control functions. 1. Friendly man-machine interface: The operation screen is embedded in the unit, which is convenient for operation and good protection. Fully computerized automatic control to realize unmanned operation. Intuitive LCD interface, multi-language and multi-menu display data and parameter adjustment, can display the operating status and temperature and humidity parameters of the main components such as the compressor, and the operation status is clear at a glance. 2. Unit control and operation management: advanced microcomputer intelligent control system, built-in control algorithm specially designed by climaveneta, more prominent energy saving and reliability of the unit, can realize the functions such as round-robin, standby machine self-starting, etc. Change the main control strategy to control the unit based on the return air temperature; 3. Network communication and building control functions: support building control connections. 4. Fault protection, alarm and analysis capabilities The microcomputer intelligent controller has perfect fault protection, alarm, recording and analysis functions, and has protection functions such as high and low voltage switches, phase loss, overload, overcurrent, overheating, and exhaust temperature, and realizes The fault record and alarm display can record 100 faults for fault diagnosis after the fault occurs, quickly eliminate the fault, and improve the technical support effect.

Chilled water coil：

The large plate design is adopted, and the fins of the heat exchanger are treated with hydrophilic treatment, which effectively improves the heat exchange efficiency. The pressure bearing capacity of the chilled water coil is greater than or equal to 1.6MPa, which effectively eliminates the hidden danger of leakage.

Water flow control valve：

Using the dynamic balance adjustment method of water flow, two-way or three-way can be configured according to project requirements. The action response is fast, and the cooling capacity adjustment is more precise.

EC fan：

The direct drive technology of EC fans is adopted, which is permanently self-lubricating and does not require maintenance; it supports hot swapping, which is convenient for replacement; it can realize stepless speed regulation and save 20-25% energy compared with ordinary fans; Reliability; 4-5 decibels lower than ordinary fan noise.
