Yes. A refigerator needs to radiate heat.
No. Evaporation and condensation is enough.
Radiation does not require matter.
It's because of radiation that as you know black body is an ideal radiation body for good radiation and so good heat transfer.
The transfer of energy that does not require matter is called radiation. Radiation can propagate through empty space, such as in the form of electromagnetic waves like light or heat.
Radiation refers to energy emitted in the form of waves or particles from a source, such as electromagnetic radiation or particle radiation. It does not require other particles because radiation is capable of propagating through a vacuum, unlike other forms of energy transfer that rely on a medium for transmission.
Radiation is a form of heat transfer that does not require matter as a medium. Energy is transferred through electromagnetic waves, such as from the sun to the Earth.
Refrigerators typically require a type of Freon called R-134a.
Radiation does not require a medium like a heated liquid to transfer energy. Radiation can transfer energy through electromagnetic waves, such as light or infrared radiation, and can travel through a vacuum. Heat transfer by radiation relies on the emission and absorption of electromagnetic waves between objects.

No, heat radiation does not require a medium to travel. It can travel through a vacuum since it consists of electromagnetic waves. This is why the Sun's heat reaches us on Earth through the vacuum of space.
Radiation is the heat transfer that does not require the presence of particles. It can occur through empty space as electromagnetic waves, transferring heat energy in the form of infrared radiation.
Equipment sent into space like satellites require thick radiation shielding due to a lack of an atmosphere. In space, radiation exposure is considerably higher than on Earth.
