1. a conditioner (1), is characterized in that, comprising:

  • Refrigerant loop (10), it is formed by connecting compressor (21), condenser (23), expansion mechanism (41,51) and evaporimeter (42,52), and cold-producing medium can be circulated;

    To the fluid delivery mechanism (28) of described condenser (23) conveying fluid;

    The condensation temperature detecting the physical quantity of the condensation temperature for asking for cold-producing medium knows mechanism (33);

    Detection is used for asking for the fluid temperature (F.T.) of carrying out the physical quantity of the temperature of the described fluid of heat exchange with the cold-producing medium in described condenser (23) and knows mechanism (36);

    WithControl part (8), its using the degree of subcooling of the cold-producing medium near described condensator outlet divided by knowing condensation temperature that the detected value of mechanism (33) is known according to described condensation temperature and knowing that the value of the poor gained of the fluid temperature (F.T.) that the detected value of mechanism (36) is known is as desired value according to described fluid temperature (F.T.), control at least one in described compressor (21), described expansion mechanism (41,51) and described fluid delivery mechanism (28)Described refrigerant loop (10) flow direction had by switching cold-producing medium switches No. four transfer valves (22) for blowdown firing and warming operation,Described control part carries out described control using more than 0.15 and lower than the identical value of 0.75 as described desired value described confession in blowdown firing and arbitrary running of described warming operation.
