A heating, ventilation, and air conditioning (HVAC) system of a building includes a refrigerant loop. A monitoring system for the HVAC system includes a monitoring device installed at the building. The monitoring device is configured to measure a first temperature of refrigerant in a refrigerant line located between a filter-drier of the refrigerant loop and an expansion valve of the refrigerant loop. The monitoring system includes a monitoring server, located remotely from the building. The monitoring server is configured to receive the first temperature and, in response to the first temperature being less than a threshold, generate a refrigerant line restriction advisory. The monitoring server is configured to, in response to the refrigerant line restriction advisory, selectively generate an alert for transmission to at least one of a customer and an HVAC contractor.

A monitoring, control and feedback system for a refrigeration unit is provided that includes a wireless transceiver operably connected to the control circuitry of a refrigeration unit. The transceiver is operably connected to the central processing unit (CPU) of the refrigeration unit and receives signals from the CPU regarding the operation of the refrigeration unit. The transceiver wireless communicates these signals to a program or application stored and operating on a suitable user device that displays the signals illustrating the current operational parameters of the refrigeration unit on the user device while also enabling the user to control the operation of refrigeration unit remotely.

Embodiments of the present disclosure are directed toward systems and method for cooling a refrigerant flow of a refrigerant circuit with a cold cooling fluid flow from a thermal storage unit to generate a warm cooling fluid flow, thermally isolating the cold cooling fluid flow and the warm cooling fluid flow in the thermal storage unit, and cooling the warm cooling fluid flow from the thermal storage unit in a chiller system to at least partially produce the cold cooling fluid flow.

Disclosed herein are an apparatus, method and system for storing perishable items that degrade in the presence of oxygen and/or humidity and that are frequently accessed by a consumer. The apparatus comprises an openable insulated vessel with precisely controlled internal temperature and humidity, which becomes airtight when closed, and a corona ozone generator with an oxygen gas feed tank and fan within the insulated airtight enclosure, which converts ambient oxygen trapped within the airtight enclosure into ozone by circulating the enclosed volume of air through the corona ozone generator after the vessel is opened and then closed. Also disclosed is a refrigerated embodiment of the apparatus, which may be self-contained and transportable. The apparatus is network connected to allow for remote control and monitoring and sends alerts to web applications or mobile applications when monitored parameters substantially vary from their settings.

A system and a method that utilizes wet proppants when creating fracturing fluid by receiving wet fracturing sand at a surge tank, vibrating the wet fracturing sand located within the surge tank, liquefying the wet fracturing sand within the surge tank based on the vibration, and metering the liquefied wet fracturing sand from the surge tank to a blending tub.

A power consumption output device is provided with a power consumption information acquiring unit and an output unit. The power consumption information acquiring unit is configured to acquire power consumption information indicating power consumption of a home appliance. The output unit is configured to output the power consumption of the home appliances along with a reference value. The power consumption of the home appliance is obtained based on the power consumption information acquired by the power consumption information acquiring unit.
