Condition monitoring and fault detection of rolling machine elements is considered a key aspect as it ensures continuously decreased cost, unplanned downtime, and unexpected breakdown. The application of condition indicators is considered one of the most effective and popular methods for the detection of faults in machine elements. Condition indicators play a vital role in fault diagnosis because of their ability to quantify the changes in the vibration signals and thus provide key information about the state of various rolling machinery elements at subsequent levels of a fault i.e. from the initial level of a fault to its substantial level. However, the articles quoting condition indicators for the detection of faults in various rolling machinery elements are still less in number. So, there is a need for more work on the application of condition indicators for fault detection in machine elements. In this paper, various condition indicators are discussed domain-wise along with their mathematical expression & characteristics and then after the various application of the condition indictors to fault diagnosis are also briefed. The goal of the paper is to put forward a comprehensive review on the application of condition indicators for fault detection in machine elements to provide the researchers with a good and wide set of references for their future research works. This paper immensely reviews and classifies important papers and articles on conditional indicators on the basis of adopted methodologies. Finally, open problems are stated and future research prospects are also pointed out.

In this paper, the performance assessment of a hybrid active greenhouse solar dryer is carried out under no load condition. The hybrid greenhouse solar dryer consists of evacuated tube solar collector and heat exchanger kept inside the dryer that also act as the drying bed. The performance of developed dryer is evaluated with and without evacuated tube solar collector. The maximum room temperature inside the dryer with collectors is found 21.4% higher than the dryer without ETC. The average temperature difference between the room and ambient air temperature for the case of dryer with collector is 16°C while in case of dryer without ETC it is 7.51°C only. Hence the developed dryer is effective for drying of high moisture crops.

Air conditioning system is most required element in indoor cooling. Energy demand for indoor cooling is increasing considerably. Also, energy price is not easy to offer. Air conditioning systems will work on Vapor Compression cycle concept, in which Compressor consume most part of the energy input. Compression is done for increasing temperature of the refrigerant before sending to the condenser to achieve super heating of the refrigerant. Energy demand by compressor can be reduced by installing the solar water heater, to heat the refrigerant before sending to compressor, this reduces the energy consumption of the compressor, with this use of the electricity will be reduced by 30-40 %. This Hybrid air-conditioning system is cost effective and environmentally friendly.
