    摘要： Provided is a highly reliable refrigerating device in which appropriate protection control is reliably performed even during a startup of a compressor in a case where a temperature of a refrigerant is measured outside of the compressor and the protection control is performed based on this temperature. An air conditioning device (1) comprises a compressor (31) which compresses a refrigerant, a discharge pipe temperature sensor (51), and a protection control section (41c). The discharge pipe temperature sensor detects the temperature of the refrigerant discharged from the compressor on the outside of the compressor. The protection control section judges that a transition following a starting of the compressor is in effect and that a steady state following an end of the transition in which a state of the refrigerant is stable is in effect, performs protection control on the compressor when the discharge pipe temperature detected by the discharge pipe temperature sensor exceeds a first determination temperature during the transition, and performs the protection control on the compressor when the discharge pipe temperature exceeds a second determination temperature during the steady state.

    摘要： A radiator (50) is a radiator that cools an indoor space (50a, 50b) by sucking in cold water from a heat source unit (10) and comprises a heat exchanger (52), a first piping (5a), a three-way valve (54), a heat exchanger temperature detection unit (56), and a control unit (60). In the first piping (5a), the cold water flows from the heat source unit (10) side to the heat exchanger (52) side. The three-way valve (54) adjusts the flow volume of the cold water flowing through the heat exchanger (52). The heat exchanger temperature detection unit (56) is capable of detecting the temperature of the heat exchanger (52). The control unit (60) performs a first cooling control that controls the three-way valve (54) so that the temperature of the heat exchanger (52) detected by the heat exchanger temperature detection unit (56) is greater than or equal to the dew point temperature of air inside the indoor space (50a, 50b).

    摘要： A radiator ( 50 ) cools and/or heats by sucking cold water or hot water from a heat source unit ( 10 ). In addition, the radiator ( 50 ) comprises a heat exchanger ( 52 ), a first piping ( 5a ), a three-way valve ( 54 ), a heat exchanger temperature detection unit ( 56 ), and a control unit ( 60 ). The first piping ( 5a ) is a piping wherethrough water flows from the heat source unit ( 10 ) side to the heat exchanger ( 52 ) side. The three-way valve ( 54 ) assumes a first state and a second state. In the first state, a flow of the water from the heat source unit ( 10 ) side to the heat exchanger ( 52 ) side is permitted. In addition, in the second state, the flow of the water from the heat source unit ( 10 ) side to the heat exchanger ( 52 ) side is blocked. The heat exchanger temperature detection unit ( 56 ) is capable of detecting a water temperature. The water temperature is the temperature of the water flowing to the heat exchanger ( 52 ). The control unit ( 60 ) comprises a water temperature determination unit ( 66 ) and an operation unit ( 64 ). The water temperature determination unit ( 66 ) determines whether the water temperature detected by the heat exchanger temperature detection unit ( 56 ) is within a prescribed temperature range. The operation unit ( 64 ), based on a determination result of the water temperature determination unit ( 66 ), sets the three-way valve ( 54 ) to a state selected from the group consisting of the first state and the second state.

    摘要： An air conditioner has an indoor fan (8) driven by a motor (26), a shutter (30) for opening and closing an lower outlet (22b), a shutter driving section (31) for driving the shutter (30), a fan control section (11a) for controlling a rotation speed of the fan (8), and a shutter control section (11b) for controlling the shutter driving section (31). When the rotating speed of the fan (8) is a prescribed rotation speed or higher at a time of opening or closing the shutter (30) in operation of the fan (8), the shutter control section (11b) controls the shutter driving section (31) in such a way that the shutter (30) is opened and closed at a high speed in a first section and at a low speed in a second section. The first section is a portion of an opening/closing section ranged from a fully closed position to a fully opened position of the shutter (30) and is located beside the fully closed position. The second section is a residual portion of the opening/closing section and is located beside the fully opened position. Meanwhile, when the rotating speed of the fan (8) is lower than the prescribed rotation speed at the time of opening or closing the shutter (30) in operation of the fan (8), the shutter control section (11b) controls the shutter driving section (31) in such a way that the shutter (30) is opened and closed at a low speed in the opening/closing section.

    摘要： An air conditioning apparatus is provided with an indoor fan (8) for blowing air, upper and lower air blowing ports (22a, 22b) for blowing the air supplied from the indoor fan (8) for air conditioning, a lower shutter (30) for opening and closing the lower air blowing port (22b), and a shutter driving section (31) for driving the shutter (30). After stopping operation of the indoor fan (8), the shutter (30) is driven by the shutter driving section (31) to have the lower air blowing port (22b) fully opened. When the shutter (30) is fully opened, a side surface of the shutter (30) forms a part of a lower wall surface among wall surfaces of a lower air blowing path (P2) for leading the air supplied form the indoor fan (8) to the lower air blowing port (22b).
