Pipe system characteristics Design of the heating system for a slab heated warehouse Esteban Goyes Gabriel Cabezas Carlos Jarrín Luis Naranjo Results Simulations Objectives Description of the problem Conclusions • Design a heating method in the building which involves embedding tubing in the concrete slab to reach the objective temperature ( 70 ° F) • Perform a heat transfer simulation using Inventor Nastran to analyze the heat transfer present along the warehouse • Select an appropriate pumping system to transport the heating fluid through the tubing system • It is wanted to design a heating system for a warehouse that stores paint containers at a temperature of 70 ° F Heat Transfer NRC: 1828 Design Parameters Thickness Concrete slab (50 ft x100 ft) 8 in Sheet metal structure (Insulated) Walls (12 ft) 4 - in (Insulation) Ceiling 6 in (Insulation) Time Temperature Daytime 65 ° F Nighttime 40 ° F Desirable temperature 70 ° F • The resultant design has a temperature variation of the water between 73 94 ° F and 89 37 ° F through all the copper pipes, that is enough to maintain the warehouse to a constant temperature of 70 ° F • The pump selected has a head of 40 4 m, with a power input of 2 03 kW and with an efficiency of 19 6 % This characteristics for the pumping system accomplished the required heating temperature • At nighttime there is the highest heat losses, so it is the critical scenario That is why the water temperature is increased to overcome the losses and maintain the constant temperature of 70 ° F Figure 1 Pipe System Design Figure 2 Thermal simulation of the wall (12ftx50ft) Figure 4 Thermal simulation of the ceiling Figure 3 Thermal simulation of the concrete slab
