24 用于检测HVAC系统中故障的方法 CN200580048953.4 2005-12-21 CN101443094A 2009-05-27 P·康; M·法扎德; A·芬; P·萨德夫
蒸发器的旁通系数用来指示何时HVAC的空气过滤器堵塞。旁通系数表示不与蒸发器直接接触而旁通的空气值。当空气过滤器堵塞时,旁通系数减小。旁通系数还可用于空气过滤器堵塞的早期检测。第一旁通系数是利用温度测量值计算的,第二旁通系数是利用空气的气流速率计算的。两个旁通系数之间的差确定误差。误差的增大指示空气过滤器被堵塞。还可以计算蒸发器的性能系数来检测空气过滤器是否堵塞。性能系数的减小指示空气过滤器被堵塞。

Disposed is a contaminant recovery receptacle (40) which is connected, through an inflow pipe (42) and an outflow pipe (43), to the suction side of a compressor (21). The inflow pipe (42) has an exit end which opens towards the inner bottom of the recovery receptacle (40). The outflow pipe (43) has an entrance end which is situated above the exit end of the inflow pipe (42) in the recovery receptacle (40). Firstly, a preliminary operation is carried out which causes refrigerant to circulate in a refrigerant circuit (10) for a predetermined length of time so that gas-liquid two-phase refrigerant flows into the recovery receptacle (40). Thereafter, a recovery operation is carried out, which causes refrigerant to circulate in the refrigerant circuit (10) so that gas refrigerant flows into the recovery receptacle (40). As a result, contaminants are recovered in the recovery receptacle (40).

38 Method for detecting a fault in an HVAC system US11028805 2005-01-04 US20060144232A1 2006-07-06 Pengju Kang; Mohsen Farzad; Alan Finn; Payman Sadegh
A bypass factor of an evaporator is used to indicate when an air filter of an HVAC is clogged. The bypass factor represents the amount of air that is bypassed without direct contact with the evaporator. As the air filter clogs, the bypass factor decreases. The bypass factor can also be used for early detection of clogging of the air filter. A first bypass factor is calculated by using the temperature measurements, and a second bypass factor is calculated by using the airflow rate of the air. The difference between the two bypass factors determines the error. An increase in the error indicates that the air filter is clogged. A coefficient of performance of the evaporator can also be calculated to detect if the air filter is clogged. A decrease in the coefficient of performance indicates that the air filter is clogged.
39 Refrigerating apparatus US09138747 1998-08-24 US06192696B1 2001-02-27 Daisuke Shimamoto; Tomohiko Kasai
In a refrigerating apparatus using a non-azeotropic refrigerant, the composition is included among the quantities of state of a refrigerant, so that it is difficult to detect the state of the interior of the refrigerant circuit. For this reason, it is difficult to stabilize the operation of the refrigerating apparatus by detecting the state of the interior of the refrigerating apparatus, and avoid the malfunction of the refrigerating apparatus. The cyclic composition of the refrigerating apparatus is detected, and the state of the interior of the refrigerating apparatus is detected accurately by using this cyclic composition. In addition, the refrigerating apparatus is arranged such that in a case where there is a quantity of state which cannot be detected accurately owing to an error or the like of the detected cyclic composition, that value can be detected directly. As a result, it is possible to accurately detect the malfunction of the refrigerating apparatus and avoid this state.
