1 Unico and Spot Cooling Unispot

2 ASHRAE defines spot cooling as Cooling the air of a limited portion of the enclosed space

4 The Problem A hot environment will make employees less productive, lead to low morale and absenteeism Because of the load required the plant manager may not think it is feasible to provide air-conditioning to a hot environment

5 OSHA Act of 1970 Heat Stroke Heat Exhaustion Heat Cramps Heat rash OSHA Information

6 The Solutions 1. Large Roof Top System 2. Portable Spot Cooler 3. Unico System for Spot Cooling (Unispot)

7 Large Rooftop Very expensive Takes a lot of electrical power Heavy Has to run 24/7 in hot weather

8 Portable Spot Cooler Usually rents by the month Cools one person, dumps the heat onto another Condensate is rarely drained, causing water to wind up all over the floor

9 Unico Unispot Cools the worker, not the workplace Operates only when people are working Much colder and faster air than conventional systems Can contribute to better IAQ

10 Unico for Spot Cooling

11 The Process Sizing the load Providing Fresh Air Unico System Operation

12 Sizing Just look at two factors: How hot does the space get? How many employees will be working in this environment Usually One Ton of Cooling per person, Five Outlets per person

13 Calculating Your UniSpot TM Needs (Continued) Inside Plant Temp Number of Outlets per workstation Number of Outlets per system USK5 10 to USK5 13 to 15 # of workstations heated or cooled USK8 15 to USK8 20 to USK12 25 to USK12 30 to 35

14 Fresh Air Most hot environments also have VERY poor IAQ We usually try to provide 100% outside air because It is cleaner than the air in the space It is cooler than the air in the space Economizers

15 Economizers can provide fresh air from the outside when the outside temperature is below 70F

16 The Unispot System Same as a Unico System in a residential application EXCEPT: Only five outlets per ton Always use metal plenum Keep supply runs short (4 to 6 feet is ideal) Always use aluminum tube supply

17 The Unispot System If people are stationary, such as an assembly line we will have five outlets per person, like shower heads If people are moving about, we put one supply duct for every three feet. Use the standard Unico PSC air handler and a generic 13 SEER condensing unit On/Off Switch
