Frequency conversion renovation
For the air-conditioning system accounted for 40% -60% of the building's total energy consumption, the growing air - conditioning electricity accounts for a large proportion of the running costs of buildings or factories. And how to carry out energy-saving transformation on the chiller unit which accounted for about 50% of air - conditioning energy consumption is the most important part of the entire system. Due to significant loads changes at different moments in different seasons, the central air-conditioning chiller which is designed to meet peak loads needs of the building is usually run at partial loads, resulting in increased energy consumption of the unit capacity. For frequency conversion renovation of Carrier centrifugal unit, it can maintain the efficient functioning of the central air - conditioning system with a new frequency conversion technology, which has relatively little energy, and the energy saving potential is up to 15% to 40%.
Energy efficiency upgrade
After a long-running of air - conditioning units, many factors shall lead to energy efficiency decreases of air – conditioning system, including heat exchanger fouling, non-standard water treatment, compressor bearing wear, aging electrical system, unreasonable configuration, inexperience or negligence of human management, service life longer than the design of the plant and others. Therefore, after running of the air - conditioning system for some time, it is necessary to conduct a comprehensive assessment on the air - conditioning system so as to understand the situation of energy use of the air-conditioning systems and provide the best maintenance and upgrade program. Carrier energy efficiency upgrade can guarantee customers cold / heat needs, while minimizing the energy consumption of the air - conditioning systems, including the old unit updates, freezing station automatic control, intelligent buildings integrated optimization, overall upgrade of cold station and other local transformation.
Non-chemical water treatment
Chiller cooling water circulating is required to go through the tower, in this process, various impurities can enter into the circulating cooling water through the cooling tower system, leading to serious problems of fouling, corrosion condenser of chillers, and there is thermal resistance increase of the condenser heat exchanger brass, the condensing temperature and condenser temperature difference increases. According to the "Civil Heating, Ventilation and Air - Conditioning Specification (GB50736-2012)", if the condensing temperature is lower, the chiller cooling coefficient may be higher and power consumption may be decrease. When evaporation temperature is constant, condensation temperature is increased by 1 degree, the cooling capacity power consumption of the compressor unit is increased by about 3% -4%. For hard dirt, debris and bacteria and algae organisms of the cooling water system, Carrier has introduced three non-chemical water treatment solutions: ionization suck dirt, ball cleaning and electromagnetic water treatment with on-line cleaning and sustained energy conservation, which do not use chemical agents, but can achieve energy conservation and environment protection.
