Some 200,000 mail carriers have reached a tentative contract deal with the U.S. Postal Service that includes backdated pay raises and a promise to provide workers with air-conditioned trucks.
The new agreement, which still needs to be ratified by union members, runs through November 2026. Letter carriers have been working without a new contract since their old one expired in May 2023. Since then they have continued working under the terms of the old contract.
Both the union and the Postal Service welcomed the agreement, which was announced Friday.
It doesn’t get to cool, for the exact same reason you don’t intake from outside to begin with.
Cool can’t happen without gradual lowering of the input temperature by recirculating it. It takes many cycles to have any impact at all.
cooling can absolutely happen with air from outside, it just takes a much more powerful ac unit. insulation only exists to make it efficient.
You can definitely use outside air for the AC.
