Refrigerant circulating system |
摘要 |
<p>The system uses a non-azeotropic mixture as refrigerant and comprises: a main refrigerant circuit connected by a compressor (1), a four-way valve (2), an outdoor heat-exchanger (3), a first throttling device (4a-c), a plurality of indoor heat-exchangers (5a-c), and a low-pressure receiver (6); a bypass circuit diverging from the discharge portion of the compressor (1) and extending through a composition detecting heat-exchanger (9) and a second throttling device (8) to the low-pressure side; an outdoor fan (7) associated with the outdoor heat-exchanger (3); a first temperature detector (103) to detect refrigerant temperature upstream of the second throttling device (9); a second temperature detector (104) to detect refrigerant temperature downstream of the second throttling device (8); a first pressure detector (102) to detect pressure downstream of the second throttling device (8); a third temperature detector (105a-c) to detect temperature in the main circuit between the first throttling device (4a-c) and the indoor heat-exchangers (5a-c); a fourth temperature detector (106a-c) to detect temperature at the low-pressure side; a second pressure detector (101) to detect the pressure at the high-pressure sides a device (21) for calculating the composition of the mixture refrigerant, a main controller (22) for controlling the speed of the compressor (1) ) and the speed of the fan (7) on the basis of the refrigerant composition and pressure; and a controller (23) for controlling the opening of the first throttling device (4a-c). <IMAGE></p> |
