1 A/C Final Project: Design Builder Tom Christen

2 House Design Back View Front View

3 House Layout

4 Location Information Location: Buffalo, NY Latitude: o N (25 o in Dubai) Longitude: o W Winter Design Weather Data: – Outside Design Temperature: o C – Wind Speed: 16.5m/s Summer Design Weather Data: – Max Dry Bulb Temperature: 30.1 o C – Coincident Wet-Bulb Temperature: – 21.5 o C – Min Dry-Bulb Temperature: 20.6 o C

5 Materials: External Walls: (outside to inside) – Brickwork (Inner Leaf) – 10cm – XPS Extruded Polystyrene – 7cm – Wood Blocks – 10cm – Glass Wool – 5cm – Gypsum Plaster – 1.3cm Roof: – Asphalt Tiles – 2.5cm – Air Gap – 1cm – Roofing Felt – 0.5cm – Glass Wool – 8cm Internal Partitions: – Gypsum Plaster – 5cm – Air Gap – 10cm – Gypsum Plaster – 5cm Ground Floor: – Oak (Radial) – 3cm – Glass Wool – 7cm – Wood Blocks– 10cm – Cast Concrete – 10cm External Windows: – Double Paned – 10% glazed Sunroom Window: – Quadruple Paned – 20% glazed External Door: – Steel – 4cm Internal Door: – Pine – 3.5cm

6 Heating/Cooling Systems Split Central A/C Unit – The outdoor cabinet (shown below) contains the condenser and compressor. An indoor cabinet contains the evaporator. – The indoor cabinet also contains a furnace. Heating: – Fuel: Natural Gas – Heating System COP: 0.8 Cooling: – Fuel: Electricity from grid – Cooling System COP: 1.6

7 Heating and Cooling Loads Overall, I took data for 6 different scenarios – 4 House Orientations (Sunroom facing North, South, East, and West) Looking for best and worst case scenarios – 2 House Relocations (Hot and Frigid Climates) Compare Buffalo, NY to extremely hot and extremely cold climates

8 Heating and Cooling Loads Orientation 1: West Heating Results: – Design Capacity: 24.87kW – Top 3 Room Heating Requirements: Family Room: 4.03kW (16%) Den + Game Room: 3.67kW (15%) Kitchen: 3.12kW (13%) Cooling Results: – Design Capacity: 10.11kW – Top 3 Room Cooling Requirements: Sunroom: 3.47kW (34%) Kitchen: 1.88kW (19%) Family Room: 1.34kW (13%)

9 Orientation 1 Temperature and Heat Gain

10 Heating/Cooling Loads (Continued) Orientation 2: North Heating Results: – Design Capacity: 24.82kW – Top 3 Room Heating Requirements: Family Room: 4.03kW (16%) Den + Game Room: 3.66kW (15%) Kitchen: 3.12kW (13%) – Sunroom: 2.18kW (9%) – Same energy req. when large sunroom window faces N or S. Cooling Results: – Design Capacity: 7.84kW – Top 3 Room Cooling Requirements: Kitchen: 1.56kW (20%) Sunroom: 1.34kW (17%) Family Room: 1.14kW (15%) – Lower than other orientations since large sunroom window faces north. This means that the window sees no sun, and does not absorb any heat.

11 Heating/Cooling Loads (Continued) Orientation 3: 180 degrees (East) Heating Results: – Design Capacity: 24.87kW – Top 3 Room Heating Requirements: Family Room: 4.04kW (16%) Den and Game Room: 3.67kW (15%) Kitchen: 3.12kW (13%) Cooling Results: – Design Capacity: 9.29kW – Top 3 Room Cooling Requirements: Sunroom: 2.95kW (32%) Kitchen: 1.49kW (16%) Den and Game Room: 1.17kW (13%)

12 Heating/Cooling Loads (Continued) Orientation 4: South Heating Results: – Design Capacity: 24.83kW – Top 3 Room Heating Requirements: Family Room: 4.00kW (16%) Den and Game Room: 3.67kW (15%) Kitchen: 3.12kW (13%) – Sunroom: 2.18kW (9%) – Do not save any energy with this large south facing window when compared to orientation 2 (90 degrees). Cooling Results: – Design Capacity: 10.52kW 3kW higher that north orient – Top 3 Room Cooling Requirements: Sunroom: 3.04kW (29%) – faces sun at all times – over 200% higher than when sunroom faces north Kitchen: 1.71kW (16%) Master Bedroom: 1.69kW (16%)

13 Results Best Case: – Heating: Very little fluctuation when rotating house. Maximum heating load change of 0.04kW. – Cooling: Minimum cooling load when sunroom faces north (receives no sunlight). Overall, the best case scenario of my house would be with the sunroom facing north (but then it wouldn’t be much of a sunroom!). – Heating Load: 24.82kW – Cooling Load: 7.84kW Worst Case: – Heating: Very little fluctuation when rotating house. Maximum heating load change of 0.04kW. – Cooling: Maximum cooling load when sunroom faces south (constantly faces sun). Overall, the worst case scenario of my house would be with the sunroom facing south. – Heating Load: 24.83kW – Cooling Load: 10.52kW

14 Relocation 1 Dubai, UAE Latitude: o N Longitude: o E Winter Weather Data: -Outside Design Temp: 12.3 o C Summer Weather Data: -Max Dry Bulb Temp: 42.4 o C -Coincident Wet-Bulb Temp: 24.1 o C -Min Dry-Bulb Temp: 32.6 o C

15 Relocation 1 Heating Results: – Design Capacity: 5.22kW (475% reduction from Buffalo, NY) Heating load likely due to temperature drop at night – Top 3 Room Heating Requirements: Family Room: 1.11kW (21%) Den + Game Room: 0.84kW (19%) Kitchen: 0.54kW (10%) Cooling Results: – Design Capacity: 24.38kW (240% increase from same orientation in Buffalo, NY) – Top 3 Room Cooling Requirements: Master Bedroom: 3.8kW (16%) Kitchen: 3.37kW (14%) Sunroom: 2.83kW (12%) – faces sun at all times

16 Relocation 2 Dikson Island, Russia Latitude: o N Longitude: o E Winter Weather Data: -Outside Design Temp: o C Summer Weather Data: -Max Dry Bulb Temp: 15.4 o C -Coincident Wet-Bulb Temp: 12.5 o C -Min Dry-Bulb Temp: 12 o C

17 Relocation 2 Heating Results: – Design Capacity: 50.29kW (200% increase from Buffalo, NY – 1000% increase from Dubai) – Top 3 Room Heating Requirements: Family Room: 7.79kW (15.5%) Den + Game Room: 7.06kW (14%) Kitchen: 6.56kW (13%) Cooling Results: – Design Capacity: 3.65kW (290% reduction from same orientation in Buffalo, NY – 670% reduction from Dubai) – Top 3 Room Cooling Requirements: Sunroom: 2.84kW (78%) – faces sun at all times Laundry Room: 0.45kW (12%) – laundry equipment heats up room Kitchen: 0.36kW (10%)
