PROBLEM TO BE SOLVED: To provide a heat pump type air cooling device which maintains air-cooling capacity high during a simultaneous operation of air-cooling and heating of a heated fluid, and which can execute pump-down.SOLUTION: A heat pump type air cooling device includes: an evaporator (41); a first condenser (61) for performing heat exchange between a refrigerant and a heated fluid; a second condenser (51) for performing heat exchange between the refrigerant and outside air; a compressor (46) for compressing the refrigerant sent from the evaporator (41); and first refrigerant flow control means (71, 73) for selectively forming a first refrigerant flow in which the refrigerant sent from the compressor (46) is supplied toward the first condenser (61) and the second condenser (51) arrayed in series on a refrigeration circuit (21), and a second refrigerant flow in which the refrigerant sent from the compressor (46) is supplied toward the first condenser (61) and the second condenser (51) arrayed in parallel on the refrigeration circuit (21). |
