For many critical refrigerators and freezers such as for medical applications, the door opening need to be monitored\"refrigerator-monitoring-scheme-drawing\"<\/a> continuously. The door should be opened for only short intervals and there should be sufficient duration between door openings.<\/p>\n

Medical Refrigerators and freezers used for storage of medicine, vaccine, plasma, blood samples etc. will have such restrictions since increase in temperature will affect the stored items.<\/p>\n

This article is applicable for the following types of refrigerators:<\/p>\n

    \n
  1. Clinical refrigerator<\/li>\n
  2. Pharmacy refrigerator<\/li>\n
  3. Medical refrigerator<\/li>\n
  4. Vaccine refrigerator<\/li>\n
  5. Plasma freezer<\/li>\n
  6. Laboratory refrigerator<\/li>\n<\/ol>\n

    Why the door opening of a refrigerator has to be monitored?<\/h2>\n

    As soon as we open the refrigerator door, the ambient air enters the chamber. This causes the inside air to heat up. As the interior of a refrigerator is very small, the temperature rises very quickly. In order to limit damage to the stored goods, we need to monitor and limit the door opening. Combined with the recording of temperature, you can analyze the temperature variations during these door openings. Also this will help you analyze the recovery time after the door is closed. We can provide remote refrigerator monitoring solutions for all these applications.<\/p>\n

    What are the parameters to be recorded for a refrigerator?<\/h3>\n

    The following parameters should be ideally monitored in a refrigerator.<\/p>\n

      \n
    1. Temperature (Please find our page on temperature monitoring of refrigerator<\/a>)<\/li>\n
    2. Door opening to analyze the frequency of opening once a door is closed.<\/li>\n
    3. Door closing delay after a door is opened.<\/li>\n
    4. Any instance of power failure should generate an alert to a number of operators.<\/li>\n<\/ol>\n

      Remote monitoring system\u00a0\u00a0for\u00a0refrigerator door opening & temperature<\/h4>\n

      We are providing our integrated solution which measures the door opening and temperature fluctuations\"medical-refrigerator-door-monitoring\" of a refrigerator. There are two volt free contacts in the door of the refrigerator. These contacts record every opening and closing of the door. This analog signal is converted into a digital signal and is transmitted through a local Ethernet connection to a centralized computer.\u00a0These are remote monitoring systems using which a user can remotely check the conditions.<\/p>\n

      We can program the device for the temperature alert levels and also we can set a duration of the\u00a0door opening.<\/p>\n

      What are the Alarms generated if the\u00a0door is not closed after a gap?<\/h5>\n

      If the door remains open for a duration longer than the programmed time, the system generates a local beeper. Optionally it can generate a phone call, SMS or email alert if the door remains open for a long duration.<\/p>\n

      How to take the report of door opening of a refrigerator using the remote monitoring system?<\/h6>\n

      Our system records the following parameters in a centralized computer:\"recording-of-refrigerator-door-opening\"<\/p>\n

        \n
      1. The temperature inside the refrigerator (sampling interval can be programmed such as 1 min, 3 minutes etc.).<\/li>\n
      2. Every door opening and closing.<\/li>\n
      3. Power failure of the refrigerator.<\/li>\n<\/ol>\n

        We store these data in a centralized software. Customer can genereate the report for any period such as every week, every month etc.<\/p>\n
