modification of a portable ac into a chiller

hi everyone,
we are trying to convert a portable ac into a chiller to cool bottles,drinks etc by replacing the existing evaporator coils by a freezer box..the objective is to use it both as an AC as well as a chiller.

is it possible.? kindly provide some details about a portable ac like links/e-books etc.

thanks in advance;)

hi akshay, yes could be a great invention, but without seeing which country you reside I canot guess the ambiant temp if it was me I would use a fridge, for the bottles , hope they are not alcoholic.

Re: modification of a portable ac into a chiller

I would just duct the cold air into the bottom of the cooler box and out the top, being careful to arrange the bottles/shelves so as not to impede the air flow.

I would install a thermostat near the top of the cooler box and set it just above the temperature of the supply air. I would wire this parallel with the A/C thermostat. The unit would run until both the room air temp is satisfied and the box temp is satisfied. In cool weather, the unit would run just long enough to fill the box with cold air.
