 Energy Applications With more than 30 years of worldwide experience ,VAREPEDA has become a key supplier of Condenser Tube Cleaning Systems in several industrial sectors and in particular in the energy sector.Chiller efficiency of affected by evaporating temperature and condensing temperature, evaporating at a certain temperature, condensation temperature is higher, its efficiency is poor.
1997 guide to American air conditioning refrigeration institute (ARI) E (1997 GUILINE for Fouling Factors: A survey of theiapplication in today S air conditioning and refrigeration - in dustry Guideline E) of article 4.3, points out that water side Fouling resistance of the heat exchanger has significant effect on the performance of the air conditioning and refrigeration equipment, such as water cooled water chiller run at full capacity, heat exchange tube wall is clean, the chilled water outlet temperature is 7 ℃, temperature of 35 ℃ cooling water of the chiller, water chiller condensing temperature of the refrigerant is 36 ℃, the evaporating temperature is 6 ℃, the energy consumption coefficient is 0.60 kW/ton. Cooling water temperature can make the condensing temperature of water chiller.In addition in the cooling water at constant temperature if the condenser's heat transfer conditions deteriorate, also can make water chiller condensing temperature, the COP down.
The open cooling water system and air of contacts, causing water quality is not stable, and accumulated a large number of scale, dirt, and microorganisms, etc., in the condenser of the heat exchange tube surface dirt, make condenser of heat transfer deterioration, the efficiency is reduced. Dirt are generally poor conductors of heat transfer, the heat conduction coefficient is only about one over ten of the carbon steel, and compared with copper, etc. A good conductor of heat, thermal conductivity differ bigger. And with the wide application of strengthened heat transfer technology, the fouling resistance to heat transfer effect more apparent.
