That is, after the energising, outdoor motor 450 will produce rotary power, and outdoor fan 430 will be rotated motion by the rotary power of outdoor motor 450, and produce inhalation power by rotatablely moving of outdoor fan 430.Under the effect of inhalation power, air outside will flow into the inside of secondary stream 400 by left side grid 126 and right side grid 136 and back grid 142.
The extraneous air that the inside of secondary stream 400 sucks will be by outdoor heat exchanger 420, and with outdoor heat exchanger 420 in mobile refrigerant carry out heat exchange, flow into the inside of throttle orifice 440 subsequently, and be discharged to the outside by top outlet 152.
In addition, use reverse-phase compressor, control the operation of compressor 410, and improve the reliability of compressor 410 by the temperature that detects refrigerant as compressor 410.
At this moment, the temperature of refrigerant will detect by the temperature detection sensor 580 that holds in the sensor accommodating portion part 540, that is to say, temperature as the refrigerant of working fluid will be sent to sensor accommodating portion part 540, thereby temperature detection sensor 580 detected temperatures of holding in the inner space by sensor accommodating portion part 540, and detect the temperature of refrigerant.
Under the situation of carrying out the cold-room operation, when the air themperature in the space of carrying out air conditioning as the temperature of the refrigerant of working fluid smaller or equal to needs, the rotation number of compressor 410 will be reduced, make it not stop the rotation and proceed and operate, at this moment, the temperature detection sensor 580 that will hold by the inside of refrigerant flow duct 520 detects the temperature of refrigerant, and the operation of control compressor 410.
More than be illustrated at the best specific embodiment of the present invention, but the present invention is not limited to the above-mentioned specific embodiment, in the scope that does not exceed the total technical conceive of the present invention, those skilled in the art can carry out various deformation and application to it.
For example, in the specific embodiment, fixedly install temperature detection sensor 580, but temperature detection sensor 580 can be fixed also by other fixture of on-fixed fastener 600 by attachment fastener 600.
The best specific embodiment of the invention described above, the internal fixation of coolant piping is provided with temperature detection sensor, and detects the temperature as the refrigerant of working fluid.
Thus, can detect temperature more accurately as the refrigerant of working fluid.
Under the situation of the temperature that detects refrigerant more accurately, can control the operation of compressor more accurately, thereby can improve the reliability of compressor, and prevent the phenomenon that compressor sustains damage.
And the present invention need not to be provided for the support of fixed temperature detection sensor, thereby has reduced the welding operation on the outer peripheral face of coolant piping, thereby can reduce the heat fatigue phenomenon of the coolant piping that causes owing to welding operation.
Simultaneously, can improve the reliability of coolant piping.
