Articlebe mixed with conditioned air from fresh air plant inall cases. Fresh air plant will supply air at 25°C duringsummer and 20°C during winter. WSHP units willcondition the room by recirculation of fresh air andambient air.It is required to use micron filters both at suction ofre-circulated air and transforming ambient air intofresh air. During the operations in jewelry business,precious metals mix with powders, and they gatherround under culverts, channels, clothes and sheetsin significant amounts. Users pay high attention tothis issue and when they observe a powder leakageto the mains, they close all culverts and cause thefailure of entire air balance. In addition to the filters, airspeeds must be evaluated carefully. The appropriatespeed at suction inlets is 0.5-1 m/s average.In case it is required to recover extracted air and releasesufficient amount of air from existing boilers, WSHPunits in the workshop together with closed towers willmeet heating-cooling requirement of entire systemwithout needing any cooling group, by aiming the use ofsystem when the temperature in the condenser of freshair is appropriate and supplying heating battery load.The availability of production load during winter andtransit seasons enables free cooling from closed towers.In conclusion, besides improving comfort conditionsspecified under the transformation of production, anew structure where 54% of former business financeis provided for producers has been introducedwithout changing traditional production methods.38TTMD 2013
