The flat plate solar water heater, using the closed-loop oscillating heat pipes (CLOHP), was constructed and investigated. The flat plate collector consisted of 10 pipes of CLOHP and the collector area was 1.5?1 m2. Each CLOHP was made of a copper capillary tube with a 1.5 mm inner diameter, a 2.8 mm outer diameter and had 20 turns. The distilled water was used as the working fluid with a filling ratio of 50% the tube?s total internal volume. The evaporator section of the CLOHP was placed on the absorber plate of the collector, and its condenser section was wrapped around the copper tube, in which hot water flowed through. The solar water heater was tested under the solar simulator with halogen lamps generating the uniform artificial solar energy. The irradiation intensity and the water flow rate of the solar water heater were adjusted. It was found that the thermal performance of the solar water heater clearly improved with an increase in the irradiation intensity from 480 to 1086 W/m2. However, the water flow rate in the range of 1.5-3.0 L/min, had a thermal performance that was slightly different. The thermal efficiency of 0.67 was archived at the high irradiation intensity of 947-1086 W/m2. Moreover, the mathematical model to predict the thermal efficiency of the flat plate solar water heater with the CLOHPs was obtained.

Smart faucet aims to reduce the wastage of water that happened in the bathroom while using a solar water heater for a bath. It also prevents the hot water scalds due to high temperature in showers and hot water taps. It controls the hot water temperature by mixing required cold water to bring down to user-defined temperature. Users can set the temperature value in the control unit and switch it either by the switch or by using the mobile application using IoT. It takes time to reach hot water in tap from solar water heater due to long pipeline connections. So much water is wasted and time too. Users can switch the unit and make it ready for use before entering the bathroom by using the mobile application. Unless Coldwater stored in the hot water pipeline is underground water storage for recycling. Smart faucet uses NodeMCU as a controller, temperature sensor, motorized ball valves, solenoid valves, temperature knob and relays for switching the solenoid valves. NodeMCU is incorporated with the android application called ‘Blynk’. It receives and sends data to NodeMCU so that the user can monitor all the parameters like flow rate, temperature, the quantity of water used and control the unit from the mobile. The motorized ball valve is used to regulate the water flow rate. So that the ratio of hot water to cold water can be achieved. These adjustments are carried out by means of the control unit as per the decision taken according to the temperature sensor value. In the meantime, the temperature required by the user can be taken as input by means of a potentiometer. By considering the userdefined temperature and temperature sensor signal, the angle of hot water and cold-water ball valve will be modified automatically to achieve the required temperature. The solenoid valve will open and close the line for draining purposes and for use. It acts as a direction control valve. All the above processes will carry out simultaneously once the user switch ON the unit. Hence wastage of water will be stopped and valve automation is achieved.

A unique SFSWH system is proposed for domestic hot water in Kovilpatti, TamilNadu, 9° 10′N 77°52′E. This SFSWH system is successfully simulated in TRNSYS Software and the results are clarified with the similarities of parallel flow solar water heater. Firstly, a complete model of spiral flow flat plate collector is formulated in TRNSYS software and taking into an account of heat transfer, outlet temperature and efficiency which are theoretically compared with parallel flow flat plate collector by means of TRNSYS simulation program. The SFSWH system performs a function with the assist of NASA surface Meteorology and solar energy year readings and with the assist of ISRO’s solar calculator application relative to Kovilpatti, Tamilnadu, India. To prove the accuracy of TRNSYS model of the SFSWH, an experimental setup is done at kovilpatti and required results were obtained under kovilpatti weather conditions. The validation of this SFSWH TRNSYS model simulation program is completed by checking the similarities between the predicted results from software with original results. This SFSWH TRNSYS model result shows the SFSWH is functioned more effectively compared with conventional parallel flow water heater. Thus TRNSYS model is reliable and which alternates the experimentation.

Difficulty in collecting conventional energy sources as well as their economic benefits including saving of time ,money, fertilizer of higher nutrient value, availability of waste easy and comfortable cooking, health benefits including the reduction diseases and environmental benefits such as saving of forest, clear surrounding were the main motivational factors for this research. However, climate temperatures in areas are too low to enable enough biogas production in small unheated digesters to meet the energy requirements of the institute, so the objectives of were to overcome the problem of energy by solar assisted with the hot water storage tank. In this research mathematical modeling of the solar water heater was designed and the analysis of heat transfer coefficient (losses) through the flat plate collector was done and the techniques that used to reduce these losses also mentioned. From the simulation results; the effect of mesh type on flat plate collector, temperature rise, and pressure drop were characterized including flow type in the laminar and turbulent using CFD approach. The FPC was needed for the preparation of the hot water for the heating of the waste food for the selected fixed dome digester with 2m2 was designed. The effect of water mass flow rate 0.01-0.05kg/s on flat plate collector, temperature rise, pressure drop, and velocity was characterized including the variation of flow types intensity using CFD approach. The optimal temperature to this process was 37 °C.The results obtained have been validated with analytical results
