摘要： A refrigeration system includes a vapor compression loop and a purge system in communication with the vapor compression loop. The purge system includes a separator including for separating contaminants from a purge gas provided from the vapor compression loop to the separator and a movement mechanism operable to increase a pressure of the purge gas. The pressure of the purge gas drives the purge gas through the separator.

摘要： An air monitoring system includes a housing having a housing inlet and a housing outlet. An airflow is configured to pass through the housing inlet into the housing. A sensor is located within the housing. The sensor is configured to monitor at least one of a frequency of dispensation of an air cleaner from an air freshener and a level of a contaminant in the airflow. The air cleaning system is configured to transmit a sensor signal to at least one of the air freshener and a user device to at least one of: recommend a frequency for air freshening, and adjust a frequency of release of the air cleaner from the air freshener.

摘要： A detection system including a smoke detector configured to transmit a detector baseline signal to at least one of a control panel and a server (e.g., to establish at least one indoor air quality trend), and a method for monitoring indoor air quality with at least one smoke detector are provided. The smoke detector includes a processor configured determine whether a current condition indicates a need to trigger an alarm. The smoke detector is configured to measure a baseline. The detector baseline signal is used (e.g., by the control panel and/or the server) to establish at least one indoor air quality (IAQ) trend.

摘要： An air temperature and humidity control device is provided including a heat pump and a humidity controller. The heat pump has a condenser, a first evaporator, a compressor, and a second evaporator. The humidity controller includes a first contactor fluidly coupled to the second evaporator. The first contactor includes at least one contact module having a porous sidewall that defines an internal space through which a liquid desiccant flows. A liquid source is coupled to the first contactor such that a second liquid provided by the liquid source flows through the first contactor adjacent an external side of the porous sidewall. Heat and/or water vapor transfers between the second liquid and the liquid desiccant.

摘要： A contactor configured for use in a dehumidification system is provided including a plurality of contact modules. Each contact module has a porous sidewall that defines an internal space through which a hygroscopic material flows. Adjacent contact modules are fluidly coupled to form a multipass flow path for the hygroscopic material through the contactor.
