Hi guys, i would like to heat up an enclosed area of 40cm x 40cm x 50cm using a heat pump. The maximum temperature should not exceed 122 degrees Fahrenheit.

Is there a way to calculate or derive a value where i can estimate the size of heat pump needed?

A heat pump would be to use the condenser heat instead of the evaporator unit.

That's a very small area to utilise a heat pump on.

Perhaps a Peltier device may be more suitable.

It should, in theory, be possible. Suitable small compressors do exist.

Perhaps you could explain more about what is in this enclosed area. For instance, are you heating air, machine parts, other substances? What temp do you start from? How critical must the final temperature be? Why a heat-pump, in particular - other than for energy-efficiency?

i'm doing it for a school project, which has its requirements set at using heat pump. Its meant to be used as a food dryer. Temperature isn't that critical, just below 122 degrees fahrenheit rising from room temperature.

Have you determined the required heat-load for the food-dryer?

the compressors from waterdispensors,ore domestic icecube makers are very small,and therefore very handy.
