Title:
FREEZER DEVICE AND AIR CONDITIONER WITH THIS FREEZER DEVICE
Document Type and Number:
Japanese Patent JP3128480
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To enable a burning of a winding of an electric motor for a compressor to be prevented even if no expansion valve is present in an outdoor device by a method wherein a plurality of indoor devices are connected to the outdoor device and a degree of opening of the expansion valve of each of the indoor devices is increased when a temperature of refrigerant discharged from the compressor is increased more than a predetermined value.
SOLUTION: An air conditioner 1 is comprised of a plurality of indoor devices A1, A2, a plurality of outdoor devices B and an inter-device piping 2 for connecting these devices. The indoor devices A1, A2 store an indoor heat exchanger 3 and an indoor fan. The indoor heat exchanger 3 is provided with a control valve 4. As a load applied to compressors 5, 6 is varied in response to a variation of load to be air conditioned, a temperature of the refrigerant discharged from the compressors 5, 6 is changed, so that this change is detected by a sensor 15. Then, if this temperature is more than a predetermined value, a winding of an electric motor for each of the compressors 5, 6 is apt to be burnt, so that a degree of opening of a control valve 4 in the indoor device being operated is set to be higher than the present degree of opening.
