Cool
Last June the guest cabin on deck 5 of the Africa Mercy was hot than usual. The 30 years old AC unity that serves the area was operating in its lowest capacity. I would not notice it if the instructor I brought onboard was not housed there. I felt bad because my cabin on a different section of the ships was cooler. A new AC unity is being installed in place of the old one; it will improve the overall cooling of the ship, use less fuel and be environment friendly.
