Cooling of fresh air through conventional Treated Fresh Air unit (TFA) or Fresh Air Handling Unit (FAHU) is a highly energy intensive process, but the HMX-PCU meets this requirement in the most energy efficient manner. This system has Indirect Evaporative Cooling (IEC) at the 1st stage for sensible cooling and then a cooling coil (DX/CW) at the 2nd stage. By incorporating IEC at the 1st stage of the Treated Fresh Air systems (TFA), substantial energy savings can be gained. The HMX-PCU can be used in conjunction with AHUs/large chiller installations for energy savings while treating the fresh air intake in commercial buildings to improve IAQ (Indoor Air Quality) or as a TFA.
HMX-PCU (Pre-cooling units)
Some amount of fresh air needs to be pumped into air conditioned spaces to maintain a required level of IAQ (Indoor Air Quality). Similarly, for various process requirements (once-through applications), 100% fresh and conditioned air is required. HMX-PCU uses the heat exchanger DAMA to pre-cool the fresh air supplied to treated fresh air units (TFA), air conditioned spaces or air handling units in the most economical manner, thereby reducing the load on the compressors. It can be used in air conditioned industrial and commercial spaces.
