Building on the success of the Ambiator, the first comfort conditioning product launched by HMX, comes a range of high-efficiency, environment-friendly, fresh air pre cooling units, the HMX PCU-F and HMX PCU-R.
HMX PCU-F
The HMX PCU-F supplies cool fresh air to improve indoor air quality while simultaneously reducing the load on the compressor of the installed air conditioning system.
It uses our patented heat exchanger DAMA to pre cool fresh air being supplied to air conditioned spaces or air handling units in the most economical manner. DAMA works on the principle of indirect evaporative cooling (IEC) for sensible cooling of the primary air using water, without any refrigerant or compressor system. This reduces the tonnage load (TR) on the installed HVAC system which would have been otherwise used to cool the fresh air. This in turn reduces the total tonnage (TR) requirement for the project, and saves a large amount of energy that is otherwise required to condition the ambient air. The primary air is cooled without adding moisture to it and in the process the dry bulb temperature and the enthalpy of the fresh air are reduced substantially.
The standard HMX PCU-F consists of an air filter, patented dry air moist air (DAMA) heat exchanger, an optional coil (direct expansion – DX or chiller water –CHW), supply air fan and its motor. The unit is then connected to ducts that supply the clean pre-cooled fresh air to the air handling unit or directly to the conditioned space. The HMX PCU-F is also an excellent option where the entire fresh air load is handled by the chiller or a DX system. Retrofitting of the existing fresh air handling unit is also possible with PCU-F. Here the air is passed only once through the space due to which there is zero contamination. Positive pressure is maintained inside the room and hence, a separate exhaust system is not required.
This machine is available from 500 CFM to 20000 CFM in standard options, and can also be customised to suit project requirements. The PCU-F can be used in various sectors like pharma, hospitals, hotels, theatres and even applications such as process cooling or to retrofit an existing fresh air unit.
HMX PCU-R
HMX PCU-R requires pre cooled fresh air and return air is available. The objective of PCU-R is to replace inefficient and maintenance intensive energy recovery wheels, heat pipes, air-to-air heat exchangers, etc. with a more efficient and economical solution that is both reliable and sustainable. The annual energy savings with the PCU-R is substantially higher to the tune of 50–60 per cent as compared to the existing options for energy recovery devices!
The air flow is made such that the cold return air, by design available at room temperature of 24°C and 55±5 per cent RH, is used as secondary air for the HMX DAMA.
The standard HMX PCU-R is normally a double-decker arrangement consisting of an air filter, our patented dry air moist air (DAMA) heat exchanger, a supply air fan and its motor in the upper deck. The lower deck comprises an air filter, a return air fan and its motor, and a plenum. It is not possible to retrofit an existing system as a separate exhaust system is required to carry the return air to the PCU-R.
HMX PCU-R is available in sizes from 500 CFM to 6000 CFM. The PCU-R can be used for varied applications such as pubs, shopping malls, IT industries, offices, commercial complexes, etc.
