1 Packaged Rooftop Air Conditioners IntelliPak Rooftops with Evaporative-Cooled Condensers 24 - 116 Tons 60 Hz June 2006 RT-PRC018-EN. Introduction IntelliPak Rooftops with Evaporative-Cooled Condensers Why Choose IntelliPak with Evaporative- OnlyTrane offers its years of experience, Cooled Condenser? along with a tradition for technology and For building owners and tenants the cost innovation, to bring total comfort to of energy for air conditioning may be every building specially their single, largest annual operating designed IntelliPak Rooftop with expense. Businesses continually seek evaporative-cooled condenser is a part energy efficient technologies that of that tradition.

2 Provide relief from these rising costs. Trane 's legacy for quality products and In many applications, the energy saving reliable performance carries through benefits of evaporative-cooled with this energy efficient solution for condensing reduces annual operating today's building systems. costs significantly enough to provide short-term payback on the initial investment. After the payback, it's all savings. Reduced operating expense and worry- free comfort has convinced many building owners that Packaged Rooftop equipment with evaporative-cooled condensing is the right choice for their buildings.

4 Water spray wets the entire coil surface. What is evaporative-cooled Upward moving air is drawn over the condensing? wetted surface via a highly efficient large diameter composite propeller fan Unlike air to air condensers, evaporative- powered by a totally enclosed fan- cooled condensing is dependent on the cooled, variable speed drive controlled ambient wet bulb, rather than dry bulb motor. The evaporative effect releases temperature. Wet bulb is generally heat from the condenser coils to the several degrees lower than dry bulb atmosphere and the contained temperature. Utilizing the lower wet bulb refrigerant gas condenses to liquid.

5 Temperature to condense the refrigerant vapor can dramatically decrease Self-Cleaning compressor power consumption. The uniqueTrane evaporative condenser Evaporative-cooled condensers, like air- design greatly reduces mineral scale cooled, are designed with heat buildup. Unlike ordinary evaporative- exchangers and also require a cooled condensers, the design allows sump or basin to contain re-circulating the coils to flex during the refrigeration water, a pump and water spray system. cycle; flexing creates a dynamic surface By re-circulating water over the that reduces potential for scale buildup.

6 Condenser coils the heat transfer process As the coils flex, mineral deposits that is more efficiently maximized. As fresh may be left behind in the evaporation air is drawn over the wet coils, heat is process are rinsed away by the rejected into the atmosphere and the continuous water spray. Normally, no water used in the heat transfer process chemicals are needed and only minor evaporates. annual maintenance may be required. Because the wet bulb temperature is Any scale present in the re-circulating lower than dry bulb, condensing water passes harmlessly through the temperatures are naturally lowered.

In areas with high mineral Since evaporative-cooled condensers concentrations in supply water, are typically more efficient than air- customers may desire some level of cooled, less coil surface area and airflow chemical treatment to minimize scale are means reduced out buildup. door sound levels and even further energy savings.

8 Solidly Efficient The IntelliPak evaporative-cooled condenser combines a cooling tower shell with a multiple circuit heat exchanger and a variable speed drive controlled fan motor. Condenser coils are supported by a structural, welded aluminum frame and nested in a low 4 RT-PRC018-EN.
