What is difference between refrigeration air conditioner?

Answer 1

Air-conditioning is a process that simultaneously conditions air; distributes it combined with the outdoor

air to the conditioned space; and at the same time controls and maintains the required space's temperature,

humidity, air movement, air cleanliness, sound level, and pressure differential within predetermined

limits for the health and comfort of the occupants, for product processing, or both.

Refrigeration is the cooling effect of the process of extracting heat from a lower temperature heat source,

a substance or cooling medium, and transferring it to a higher temperature heat sink, probably atmospheric

air and surface water, to maintain the temperature of the heat source below that of the surroundings.

Answer 2

really not much.. principals are the same but the only thing is that when your lines in central air freeze up it usually means its low on refrigerant.. when lines freeze up on refrigerators and freezers it means there's too much refrigerant in the system..
