Answer 1

I am hesitant to answer 'cause I'm in the U.S.

We here in Kentucky have tool rental places , where people can rent expensive equipment when they only need it for one job. (jackhammers , cement mixers , generators , etc...)

I have gotten exhaust fans , and have used "blowers.

You suck air out , and exhaust it . Fresh cooler air is pulled in from other windows and exits.

Test out prior to find best direction and location.(wind direction plays an important role.)

Plastic sheeting and duct tape can aide in creating a good vacuum assuring the introduction of fresh air.

I have provided pictures of such fans , but can only tell you where to rent them here in the U.S. (sorry)

search for tool rental in your town.

Answer 2

Check with a local water restoration company(flood repair company) and ask them the cost to rent one of their large HEPA air scrubbers.  These filter a large volume of air and the air is not heated nor cooled.  Ask the restoration if they would also sprinkle a little crystal odor counteractant onto the filter before they leave.  These crystals re-odorize the air and introduces a pleasant fragrance into the air.

Answer 3

You might be able to rent (hire) an ionizer or HEPA air filter though most portable models are designed to be used in fairly small rooms. Fans won't help with odor but can make the heat more tolerable.
