RC Group quality standards for modern precision air conditioners

All the variety of modern climate equipment oriented to maintain required temperature settings inside residential or industrial buildings can be classified in many ways. It depends on capacity of used refrigerant (such as: water, refrigerant gas, liquid freon); operational principles (such as: standard chiller-fan-coil system, multi-split system, MRV system based on VRF technology etc.). One of the significant criteria is the main purpose of an air conditioner or refrigerator. According to the purpose of use air conditioners allocate in 3 groups such as: 

 

 

  • Domestic air conditioner;

 

  • Semi-industrial air conditioner;

 

  • Industrial ventilation and air conditioning.

 

 

However, such categorization is approximate and in each group one can find units that are significantly different in its construction, air-conditioning technology, a number of other parameters. Among many models of equipment the very special unit consists of the so-called precision air conditioners. Such units are specially designed to precisely maintain the temperature and humidity parameters within the conditioned space. The range of tasks includes following points:

 

  • accurate maintenance of set temperature (deviations exceeding 10C are not allowed);
 
  • regulation of relative humidity parameters within 5% +/- of predetermined level;

 

  • qualitative conditioning process in complex environments, at extremely high / low temperatures (+500С – -600С).

 

Main implementation areas of precision air conditioners are: data centers, telephone exchanges, server rooms and hardware facilities, laboratories.

 

Given the tendency of technological development nowadays, precision air conditioners gain its own wide niche so-called IT-conditioning. The use of such units becomes the only possible solution for temperature regulation in technical areas with a lot of computer equipment. It is very important to maintain a stable temperature with minimal fluctuations to provide flawless operation of powerful computers and networks. Continuous operations with a large data stream which is running by mobile communication stations, communication points, data centers, offices of computer companies and media organizations require specially designed external conditions. For such consumers were developed precision air conditioners, which today successfully operating in information sites worldwide.

 

One of the first in designing and manufacturing of precision air conditioners was Italian company RC Group which announced itself as a manufacturer of climatic equipment back in 1963. Ever since, the company specializes in creating devices for precise regulation of indoors temperature of special purposes. One of the 2 main RC Group factories located in Zeccone (Pavia) is completely oriented on production of high-precision technology.

 

What are the latest technical achievements in this specific area? They are implemented and presented in the model range of precision air conditioners from RC Group the latest build NEXT EVO. As in any model range the manufacturer provides a large variety of functions in finished equipment. Thus, series modification characterized by the following parameters:

 

 
Modification NEXT EVO INV NEXT EVO CW NEXT EVO CW PLUS
Air delivery Over flow / Under flow Over flow / Under flow Over flow 
Type of refrigerant  Freon 410А Water cooling Water cooling
Cooling capacity 7,3-102 kW 6,2 – 151 kW 114-248 kW
Specific features Scroll compressor with inverter control EC-fan with a separate section EC-fans in separate cavities under the floor

 

 

This series of precision air conditioners are optimally combines high performance with a compact size. Ease of installation, its variability (due to additional equipment) provides economical distribution of free space in technical areas (like server, communication centers, computer labs).

 

RC Group engineering of precision air conditioners elaborate in such a way that machines are qualitatively manage the key task - precise control of temperature indicators, also save energy consumption and coolant flow rate which is positively affects the efficiency and the total operational cost of such equipment.

 

The sphere of information technologies, consider its scale, continues to expand. It is necessary to provide flawless operation of computer equipment to control large information flows within strictly defined circumstances. Such conditions with a high level of reliability provide precision air conditioners from the Italian manufacturer RC Group.
