Refrigeration Systems

ST Solution designs, adjusts and mounts equipment, implements commissioning and service maintenance of refrigeration systems (refrigeration section):

• with immediate cooling

• with intermediate cold carrier (chillers, dry cools, fancoils)

• multi-zonal systems of conditioning with a possibility of simultaneous heating and cooling of different premises

• cascade

Artificial cold is required for companies, warehouses and trade facilities for storage of products, implementation of processes and arrangement of comfort conditions for personnel. Air conditioning has become a routine element of comfortable environment inside residential and office buildings. For centralized conditioning of the building coolers with refrigerating machines, pump units and heat exchangers are required operating according to fine tuned algorithm.

Functionality and efficiency of refrigeration depends on correct designing. At this stage we are calculating heat flows, determine heat loads and the required capacity of the future refrigeration system. Depending on the requirements and tasks of the project we determine the types of the main equipment, develop connection circuits and automation schemes. For power saving and optimization of a refrigeration system we suggest that Customers use a range of options:

• recovery;

• free-cooling;

• cold accumulators;

• heat exchangers with increased working surface;

• installation of variable-frequency drives and soft starters;

• installation of step-by-step and pulse electronic thermal expansion valves;

• power saving algorithms of work.

A correctly designed and mounted refrigeration system will serve for long years providing comfort for people and solving process tasks of the company.

ST Solution also integrates refrigeration systems in the central system of the facility dispatching, which enables to efficiently control conditioning, heating, ventilation and lighting of the building as a common interconnected system.

Industrial Refrigeration Systems

Artificial cold is indispensable in processes of such industries as:

• food

• oil

• gas

• metallurgy

• chemical

• nuclear

• data processing centers

Our company have realized projects on increased complexity and danger facilities with the use of ammonia (NH3), carbon dioxide CO2 and freons as cold carriers.
