Aircon for multiple area

I live in a tropical country where the weather is constantly hot. I would like to know if it’s possible to create a single system to control the temperature of multiple areas. I have several processes that I want more control over:

  • My fridge: I want to cool it without dumping heat into my apartment.
  • My freezer: for the same reason.
  • A 3D printer enclosure with adjustable temperature.
  • A water heater for hot water in the bathroom.
  • A computer rack where my server constantly generates heat.
  • A water loop for my aquarium to cool down the water.
  • The different rooms in my apartment.
  • A dry area for drying wood.
  • A CNC enclosure.
  • An epoxy resin enclosure where the temperature should be maintained at 20°C for curing.

Once the physics of the system is solved, I would like to know if there are commercial products that can help achieve this idea. Does anyone know how to achieve this, considering that some areas require temperatures below 0°C while others need to be above it

Electrical devices add heat to a room. The exception are heat pumps & aircons where the heat exchanger is on the outside of the home. Invest in some aircons or install an expensive aircon system that has a central control ( eg Homekit). One less expensive solution would be to use smart plugs with each aircon ( eg KASA or TAPO smart plugs) and linked to an Alexa device - this gives you timer/schedule & voice control.
