Using air exchanger to cool upstairs
I live in New Brunswick (Canada), climate zone 6. We have cold winters and hot humid summers.
The upstairs of the of my 2-storey houses gets quite warm in the summers. I have an HRV but I turn it off during the summer months to prevent heat and humidity from coming into the house. I don’t run an AC or heat pump during the summer and open the windows at night to bring in some fresh air.
I was wondering if I can/should disconnect my air exchanger from the outside supply line to circulate the cold air from the basement upstairs and return the hot air to the basement (disconnecting the return to avoid depressurizing the house). This would bring hot humid air to the cold basement but I have a dehumidifier that runs in the basement that maintains a constant humidity level and drains to a floor drain.
Would doing this cause and any mold or other issues I am not thinking about?
Any other better suggestions?
