Good evening to everyone.
I`ve been trying to find a rule of thumb in regards to the correct separation (distance) between the return side of a forced air type evaporator and the walk-in wall, in order to achieve an efficient airflow. So far I have not been able to find it, but someone told me that it should be about half of the evaporator total width. Does this rule make any sense to you ? I have an evaporator which is about 3.65 meters wide, which makes about 1.80 meters the recommended distance. Isn`t it too much ?Thank you for your response.
