| Tools, methods and systems for detecting and reporting the presence of an obstruction to an AC system of the present disclosure are able to detect the presence of the obstruction using one or more sensors connected to the air conditioning unit and displaying an alert on the computer system of the AC system when the sensors detect the presence of the obstruction. By displaying an alert at the computer system's output device, the presence of the obstruction is brought to the user's attention, allowing the user to take remedial action as needed before initiating the air conditioning system into operation, preventing the obstruction from harming the components of AC system if the system was initiated while the obstruction was still present. Additionally, the AC system may further disable or prevent the operation and initiation of itself when the sensors of the air conditioning system detect the presence of an obstruction. | ||||||

| A microcooler includes a substrate with a first and second microchannel and an orifice disposed between, in fluid communication with both. A pair of electrodes is in a vicinity of the orifice. An electrical resistive heating material is in electrical communication with the electrodes and is in thermal contact with a fluid in the vicinity of the orifice. A system includes the microcooler and a voltage source to apply a voltage across the electrodes, which induces sufficient heating in the heating material to disassociate something clogging the orifice, without significant damage to the heating material. Some systems include a sensor configured to detect an effect of clogging at the orifice. A processor is configured to receive sensor output from the sensor, and if there is an effect of clogging, then cause the voltage to be applied across the electrodes. | ||||||

| 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. | ||||||

| 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). | ||||||
