Energy Saving in Low Relative Humidity Air Conditioning

Energy savings at Low Relative Humidity air conditioning

Some industrial applications that require the relative humidity will be strictly followed at all levels, ranging from 25% to 45% or less with indoor air at temperatures ranging from 18 24C. traditional method of achieving this goal is to reduce the temperature of air up to a very low level (say 6 8C) seal water, then heat the cold air (with the use of electric heaters or steam coils in a duct) about 14 to 18C satisfy the room temperature and relative humidity conditions. However, there is dual energy fine, payable when you use this system, i.e. the extra energy consumption in duct heaters and additional energy consumption for compressors to dissipate this heat is added in the duct.

Using the above exchangers can transfer heat from the warm return air on 24C (say), to cold air from the air conditioner on 8C (say), thus totally eliminating the need for duct heaters. This saves duct thermal energy, and also reduces the thermal load on the compressor. The use of these heat recovery, heat exchangers have lead to savings in the amount from 30% to 60% in air conditioning energy consumption in some sectors (see case study)...
