Portable Air Conditioner/Heater II

This is another portable air conditioner prototype however this one uses an external source of coolant (as opposed to the first that used ice inside it). This model has cutouts for 4mm (or 6mm) diameter copper tubing to run inside in front of the airflow from a 120mm fan. the coolant source then can be whatever you want to be (most might use a cooler filled with ice water and a pump). You can also do the reverse and use a hot coolant source (like hot water) and use it as a heater instead.
