17. Statements An engineer wants to design an ATES system for a large office building in a moderate climate. The annual cooling demand is 200 [MWh], the annual heating demand is 800 [MWh] too. For the heating a heat pump with SCOP 8 is coupled to the warm well. The cooling comes solely from the cold well. All heat exchangers are assumed to be perfect and there are no losses in pipes. Which of these statements are correct? (Note: multiple answers possible) 200 [MWh] heat is loaded at the warm well 100 [MWh] heat is loaded at the warm well 700 [MWh] heat is load at the warm well 800 [MWh] cold is loaded at the cold well 700 [MWh] cold is loaded at the cold well 200 [MWh] cold is loaded at the cold well To balance the ground additional cold should be loaded (e.g. by using an additional heat exchanger with cold outdoor air in winter) or the heating demand should be reduced To balance the ground additional heat should be loaded (e.g. by using additional heat exchanger coupled to a solar boiler) or the heating demand should be reduced

What effects are produced by change in voltage? 1. Iron los..........varies approximately as V². 2. Cu loss..........it also varies as V² but decreases with an increase in voltage if constant kVA output is assumed. 3. Efficiency...........for distribution transformers, efficiency at fractional loads decreases with in- crease in voltage while at full load or overload it increases with increase in voltage and vice- versa. 4. Regulation..........it varies as but decreases with increase in voltage if constant kVA output is assumed. 5. Heating.........for constant kVA output, iron temperatures increase whereas Cu temperatures decrease with increase in voltages and vice-versa.
