Abstract
A refrigeration apparatus includes a refrigerant circuit in which a compressor, a condenser, a liquid receiver, a first opening-and-closing valve, an expansion valve, and an evaporator are connected sequentially by pipes and through which refrigerant circulates. The refrigerant is HFO1123 or a refrigerant mixture containing HFO1123. A ratio of a refrigeration capacity to an opening area of the first opening-and-closing valve is within a range of 0.25 to 0.6 (kW/mm).
