Question

A heat pump with a motor of 2 kW is used to keep a chicken hatchery at 30°C. This latter loses energy at a rate of 0.5 kW per degree

difference to the colder ambient. The heat pump has a COP that is 50% of a Carnot heat pump. a- Draw a sketch for the entire system showing all energy transfers. b- Illustrate a heat pump operating between two constant-temperature energy reservoirs showing all energy transfers. (5 points) - What is the minimum ambient temperature for which the heat pump is sufficient?
