Problem Statement = You install a heat pump to heat a cottage during the winter using the outside air as the heat source. You wish to maintain the interior temperature of the cottage at 22°C. A simplified model of the heat loss through the walls indicates that heat will need to be supplied at a rate of 0.14(Tinterior - Texterior) where Q is the rate at which heat must be supplied to the cottage (in kW), Tinterior is the interior air temperature (in C), and Texterior is the exterior air temperature (in C). You have a 1kW electric motor available to run the heat pump. What is the coldest winter day when the heat pump will be able to keep up to the heating demand?

There is a room with room vol: 300 M3 Maximum room temperature: 22 oC Cooling system: AHU Question : how to calculate ideal cooling capacity (BTU/hour) if 10 people worked inside for 7 hours?
Part 1: Do the Analysis of the Ocean Thermal Gradient Power Plant shown below. Your Analysis will be easier to do in EES but it is up to you. Your EES program must be well documented and documentation in your code should reference system sketches. (The cycle and individual components) These sketches are done on attached engineering or typing paper, unless you are able to draw them in EES. You must validate your results with hand calculations on engineering paper that invoke the 1 and 2 Law from the perspective of the entire cycle, not the individual components. Of course, a system sketch is required. nd 1. An ocean thermal gradient power plant using a simple non-ideal Rankine Cycle operates with a peak boiler temperature of 70 °F and a condenser temperature of 40 °F. The warm surface water of the ocean is supplying the thermal energy to the boiler. Assume a high source temperature of 80 °F. The cooler water deeper in the ocean is the sink for heat rejection at the condenser. Assume a…
