Non-standard approaches to climate systems organization in data processing centers

The article is devoted to comparison of air conditioning systems in a data processing center, taking into account peculiarities of its location, in Perm Krai, RF. It is established that the use of more expensive, but modern, hybrid air conditioning system is economically feasible in this region. Purpose of work. The aim of the work is to assess the feasibility and effectiveness of different air cooling systems from an economic point of view, under the conditions of the location of the facility in the Perm region. Materials and methods. Two cooling systems are compared. The first cooling system is based on a direct supply of cold air. This system has restrictions on the temperature of application, it can only be used at ambient temperatures lower than the temperature of the cooled room, about 20 °С. Current costs in the form of consumed electricity to cool the room in this case will be less. The second, classic air conditioning system. In which cooling occurs due to boiling of freon in evaporator and the following compression by compressor and transitions to liquid phase in condenser. There are different variations of this system for almost any climate zone. Running costs (electricity) caused by operation of this system are higher. But the initial costs are less, since this system costs less. The task is to determine whether there will be a positive economic effect from the introduction of a system with direct cold air supply. The research is done with the help of theoretical methods. For this purpose, data on the air temperature in the city of Perm for 2021 by day and hour were taken. The results of the study. Determined how many days and hours, can work one or the other system. Classical air conditioning or a hybrid system, with the possibility of direct supply of cooled air. Calculated the cost of electricity when working in the first and second modes. Determined the number of necessary climate control equipment, taking into account its redundancy under the scheme N+1. Approximate costs for the implementation of the systems have been determined. Discussion and conclusion. It was found that the cost of introducing a more expensive hybrid system with the support of direct chilled air, compared with the classical air conditioning system will pay off in a few years. Significant advantages of such systems are also identified. Longer service life due to less use of the compressor in the refrigeration system.
