Narrative:

As we were in the climb between FL250 and our final of FL280; a caution message appeared on the EICAS. The caution message for 'left pack temp' led us to the QRH and the MEL (we had the temp knob at 9 o'clock with an output of -3 degrees); we momentarily moved the temp to 12 o'clock during the descent. Because the aircraft had a right pack meled; we elected to [advise ATC] and started a descent to 10 thousand feet in order to complete the 'unpressurized flight' procedure instructed by the MEL. We assessed the situation and agreed that we had enough fuel to continue to [destination]. After a back and forth with the dispatcher regarding the situation; operations concurred and authorized us to proceed to [destination]. Nearing arrival; about 15 mins out; we asked dispatch to have the medics ready just in case as a passenger complained of feeling hot. We landed and parked as soon as possible; the medics met us at the gate to assist the passengers in case of discomfort. We then contacted maintenance and operations; we were later asked to ferry the aircraft with both packs meled.the event occurred because we were dispatched single pack; after losing the second one; we had to continue the flight unpressurized. We should have a limitation on dispatching aircraft single pack at a certain ambient temperature.

Title: CRJ-700 flight crew reported being dispatched with one pack inoperative. They had to shut down the other pack in flight because it overheated. They continued the flight to destination unpressurized.

Narrative: As we were in the climb between FL250 and our final of FL280; a caution message appeared on the EICAS. The caution message for 'Left Pack temp' led us to the QRH and the MEL (We had the temp knob at 9 o'clock with an output of -3 degrees); we momentarily moved the temp to 12 o'clock during the descent. Because the aircraft had a right pack MELed; we elected to [advise ATC] and started a descent to 10 thousand feet in order to complete the 'unpressurized flight' procedure instructed by the MEL. We assessed the situation and agreed that we had enough fuel to continue to [destination].
