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…

3.A multi-million-dollar power plant project to provide power supply for remote communities by GRIDco was stopped by the Environmental Protection agency (EPA) citing violation of the EPA’s protocols. The EPA argues that GRIDco did not conduct environmental impact assessment (EIA) on the project within the community it is located and therefore if the project is allowed to continue, it will pose public health risk to the inhabitants within the catchment area.(a) Why is it necessary to conduct EIA on such an important project? And what will be the expected outcome of the impact assessment?

Automatic lawn sprinkler systems use a digital system to control the opening and closing of water valves. A sprinkler system usually supports several different zones such as the backyard, left side yard, right side yard, front yard etc. Only one zone's value can be opened at a time in order to remain enough water pressure in the sprinklers in that zone. suppose a sprinkler system supports up to 8 zones. Typically, a sprinker system is controlled by a small, inexpensive microprocessor executing a program that opens each value only at specific times of the day and for specific durations. suppose the microprocessor only has 4 output pins available to control the valves, not 8 outputs as required for the 8 zones. We can instead program the microprocessor to use 1 pin to indicate whether a valve should be opened, and use the 3 other pins to output the active zone (0,1....7) in binary. thus we need to design a combination circuit having 4 inputs, e, and a,b,c (the binary value of the active…
