Imagine that you are a chemical engineer who has been given the task of working with a museum curator to create a display case for a rare painting that must be preserved in a controlled environment, meaning elements such as temperature, humidity, exposure to light, etc. must be constantly regulated. What kind of control system would you choose and why?

Aheat pump using refrigerant-134a heats a house by using underground water at 8°c as the heat source. the house is losing heat at a rate of 60,000 kj/h. the refrigerant enters the compressor at 280 kpa and 0°c, and it leaves at 1 mpa and 60°c. the refrigerant exits the condenser at 30°c. determine: (a) the power input to the heat pump, (b) the rate of heat absorption from the water, and (c) the increase in electric power input if an electric resistance heater is used instead of a heat pump
