Natural cooling with CoolMaster ®»CoolMaster ® is a cooling system that cools the air with the helpof an evaporative humidifier in the extract air.The refrigerant used is fresh water! The systemcontains no chemicals and needs no refrigerationmachine. CoolMaster ® is easy to install,operating costs are kept low and CoolMaster ®takes up very little space.How does it work?Evaporating water absorbs heat from itssurroundings. For example, you know thatwhen you leave the shower it is the waterevaporating from your skin that causes youto feel cold. That is why evaporativehumidifiers cool as well as humidify the air.Key components in a CoolMaster ® airhandling unit are the evaporative humidifierthat cools the exhaust air and an effectiveheat exchanger that transfers the coolingeffect to the supply air.When the outdoor temperature is high,the humidifier is used to cool the extract air.Via the heat exchanger, the exhaust air thencools the outdoor air before it enters thebuilding.How much cooler is it?Normally the temperature of the supply air canbe reduced by 4-5 degrees. The temperaturereduction is influenced by several factors.The outdoor air temperature and thetemperature and humidity of the exhaust airaffect the result. Naturally it is important tochoose an air humidifier and a heat exchangerwith a high efficiency.As the outline diagram below illustratesyou can lower indoor temperatures by 4-5 °Cand sometimes up to 8 degrees.CoolMaster ® cannot closely give you controlair conditioning, but the temperaturereduction the system gives represents significantimprovements in comfort, productivityand safety in comfort applications.Our user friendly product selection programcalculates the temperature reduction youwill get on the supply air, and providescomprehensive information about your unit.The program also calculates the total annualoperating cost and gives an estimated lifecycle cost (LCC).FloorMaster ®diffuser2127°C10g/kg27°C9g/kg22,5°CCoolMaster ® is an idealpartner for the Floor-Master ® system.14
What is the operating cost?The operating cost depends on the relevantclimate, how the system is used andlocal electricity and water costs.For a standard comfort ventilation system inthe Nordic climate, water consumption isabout 50 m 3 per year and m 3 /s air.The pressure drop across the humidifiermeans a higher energy cost to drive theexhaust air fan. This can be about 1200 kWhper m 3 air and year. However, the increasecan be halved if the cassette is removedduring the winter months.Key components in a CoolMaster ®air handling unit15
