In this write up, an energy-saving device is introduced into the air-handling unit (AHU). Due to increases in energy costs, energy saving devices or systems have become the new preferred trend in tropical countries. A primary cooling coil system is incorporated into the AHU to recycle the condensate water in order to achieve energy savings. The warm outside fresh air is drawn through the primary cooling coil to recover the latent heat of condensate water. The large temperature gradient between the warm fresh air and condensate water enlarges the amount of energy recovered. This system is well applicable to primary AHU which serves primary air to the air-conditioning system. The cost of installing the device is negligible but in returning long term saving. Furthermore, the de-cooled condensate water can be drained off through non-insulated drain pipe. The idea generation is discussed in the introduction. Chapters 2 and 3 describe the preliminary calculation of the energy saving percentage. Chapter 4 shows the detailed theoretical study of the development of the energy saving system. This shows the viability of the idea. Chapter 5 will recommend the design of the primary cooling coil configuration to achieve the desired cooling effect and energy saving strategy. Lastly, the conclusion of the whole study is presented.
We are recognized as an ace trader, supplier, distributor and wholesaler of Air Supply Units, and have emerged as a well-known and trusted name in the market. These are made available to the customers at industry leading rates. It is a unit that removes heat from a liquid via a vapor-compression and absorption refrigeration cycle. This liquid can then be circulated through a heat exchanger to cool air or equipment as required. As a necessary by-product, refrigeration creates waste heat that must be exhausted to ambient or, for greater efficiency, recovered for heating purposes.
The unit is manufactured in HEAVY duty extruded Aluminum profile with without THERMAL BREAK internal coving section.
The unit panels are filled with 25 OR 50mm thick pressure injected polyurethane foam, having 38/40 kg /m3 density.
Various options such as pre-coated galvanized sheets, plain galvanized sheets, aluminum SS 304 SS 316 sheets in various thicknesses are available for inner outer skin of double skin panels.
High efficiency, AMCA certified, imported DWDI PLUG type Blowers are used.
Forward curved blowers for normal applications and backward curved for high resistance application.
Drain pan made of SS 304 with dual slope to facilitate immediate discharge of condensate.
Base frame is made of galvanized steel with die cast aluminum joints having lifting holes.
Access doors are provided with hinges locks made of self extinguishing nylon for perfect air tightness.
