Emerson Precision Air Conditioners Review: Error Codes, Model Comparison

Emerson specializes in the design and manufacture of HVAC equipment for server and telecommunication stations. A feature of the brand's products is the ability to adapt to specific operating conditions. Precision air conditioner Emerson is a modern climatic complex with maximum autonomy.

Main lines of air conditioners and products

The company has developed systems to maintain the required temperature and humidity in rooms with high-precision equipment. The main activity of Emerson is precision air conditioners, their maintenance and repair. To choose the best option, it is recommended that you familiarize yourself with the main assortment of the brand.

In-row air conditioners

Designed for installation in server rooms, between the rows of service equipment. Emerson's in-row air conditioners blow cold air into the corridor or onto the grates of server cabinets. Such an air conditioning scheme is convenient for rooms with a small area or zonal service.

The Liebert CRV Series Emerson In-Row Unit has the following advantages:

• horizontal distribution of flows, the ability to serve a small part of the room;
• power varies from 20 to 50 kW;
• compact dimensions do not affect refrigeration performance;
• a compressor with digital Scroll control is installed, the speed of the fans is automatically controlled.

Integration with other equipment of the company is possible to create complex climatic systems.

In some models, water with special additives is used as a working fluid. A drainage regulator and a module for regulating the humidity in the room were developed for them.

Precision air conditioners for server rooms

With their help, the required level of temperature and humidity is maintained in large server rooms. Emerson's standard cabinet air conditioner can be installed indoors or outdoors. Also in the assortment of the company there is a split system HPM. The characteristics and design features of each series depend on the purpose.

The company offers the following types of cabinet units:

• Liebert W / D / H / F. The power of the units varies from 4 to 100 kW. Air cooled or water cooled options are available.
• Liebert C. Rated power - from 6 to 230 kW. Only water-cooled units can be selected. Autonomous operation is provided by the ICOM electronic control system.
• Liebert general purpose. Cooling capacity - from 15 to 70 kW. Unlike the above models, it is possible to change the configuration of the adaptation equipment for the required operating conditions. The pressure in the lines and the distribution of the cooling zone are automatically regulated.

To choose, you need to take into account the area of ​​the serviced room, the total heat energy released by the installed equipment. In some cases, exposure to a strong electromagnetic field is unacceptable.

The temperature control accuracy for the above models is 1 ° C. This value can be reduced by installing additional measuring equipment and modules to regulate the intensity of the fan operation.

Climatic equipment for telecommunication stations

Unlike the models described above, these complexes have advanced options for server rooms. Features - quick change of operating modes, choice of installation method. For optimization, a common control and monitoring module is used, integration with other climatic units of this manufacturer is also possible.

Lines of equipment for telecommunication stations:

• Cabinet Cooler. Devices with compact dimensions and high cooling density. The choice of air distribution method is possible: frontal, lateral, raised floor or combined.
• Hiline Slim. They differ in compact dimensions, direct mechanical cooling. The rated cooling power is 4 kW. There is a filtration unit, it is possible to take cold air from the street.
• High Performance Split. An innovative solution from Emerson is a split system for high-density premises. The cooling capacity ranges from 6.4 to 14.6 kW.

While the systems are complex, basic maintenance of Emerson air conditioners can be trusted by local personnel. The exception is installation and repair work. The installation of the air conditioner must be carried out by specialized professionals, otherwise the normal operation of the complex is not guaranteed.

For uninterrupted operation of the system, it is recommended to purchase an autonomous power supply, or connect climate modules to an already installed network.

Comparison of characteristics of popular models

The choice of this type of equipment is based on a comprehensive analysis of the required characteristics. The payment for non-observance of this condition is the incorrect functioning of the entire system. To familiarize yourself with the parameters, you need an instruction for air conditioners, which indicates all the characteristics.

But besides this, such factors are taken into account:

• cooling capacity minimum error value;
• the size of the room, the layout of the equipment;
• basic climatic characteristics - the degree of air heating at peak loads and stable operation.

In order not to study each technical data sheet, it is recommended that you familiarize yourself with the parameters of three popular models of HVAC equipment of this brand.

The cost is formed individually for each model. In most cases, a complete package is ordered - with a control system, possible changes in the configuration of the units. You can also buy a standard set.

The price depends on the volume of the order. It is recommended to choose direct company dealers with trained personnel. You can also order professional installation and further maintenance from them.

Emerson Control Panel and Air Conditioners Instructions

The integrated management system ICOM has been developed for normal operation. This module can be integrated into all models of the company's HVAC equipment. A remote control for the air conditioner is attached separately for changing the basic characteristics in manual mode.

The service manual contains the following information about the control unit:

• the ability to connect to a computer for remote transmission of current data;
• there is a code tunable block for setting additional parameters;
• convenient graphical display of information on the liquid crystal display;
• setting up automatic operation.

Particular attention is paid to the maintenance of the units. It is necessary to periodically clean the filters, check the condition of the dampers and louvers. After a long downtime, the start-up is carried out in the minimum mode, gradually increasing the cooling capacity.

Important - for each model, the maximum allowable temperature level in the room is set. If there is a possibility of exceeding this limit, you should choose more powerful complexes.

Emerson air conditioner error codes

The first sign of malfunctioning are error codes that appear on the screen of the control unit or remote control. If the malfunction is not eliminated in a timely manner, it will take a long time to restore the system to work.

To avoid the occurrence of such situations, you should adhere to the following rules:

• carry out activities for the maintenance of blocks;
• check the degree of contamination of the air filters;
• invite specialists for complex diagnostics at least once a year.

In the event of a breakdown, the code should be passed to a service representative. Sometimes the error is systemic and does not affect the performance of the equipment. But this can only be solved by a specialized specialist.

User reviews

Since the company's products are specific, it is problematic to find reviews about it. For a primary analysis of the actual consumer properties, it is recommended to visit specialized forums.

Benefits:

• flexibility of settings;
• the ability to integrate several modules into a common system;
• reliability of work;
• relatively easy maintenance.

The disadvantages include only the high cost. But this indicator is typical for all models of this class.
